Introduction
INTRODUCTION
The Digital Processing Systems DPS-475™ and DPS-575™ Multi-Function Analog/Digital AV Synchronizers are equally suited for analog, digital or hybrid
facilities, and represent the ideal choice for broadcasters making the transition to digital television (DTV). Available in video-only and audio/video configurations, these synchronizers provide an ideal bridge from analog video signals, such as satellite and microwave feeds, to digital production facilities. The DPS-475 is an NTSC-only model while the DPS-575 is an auto-sensing dual-standard (PAL/NTSC) device.
The DPS-475 and DPS-575 offer unparalleled I/O flexibility. Four input and five output formats are provided standard:
Serial Component Digital Video (SDI) input and output
Component Analog Video (Betacam) input and output
S-Video (S-VHS / Hi8) input and output
Composite Video input and output
RGB-S output
DV (IEEE-1394) I/O with transport control is available as an option. A built-in auto­sense TBC circuit provides seamless mode switching between direct color and heterodyne sources such as camcorders and VTRs.
The versatile DPS 12-bit comb filter offers three processing modes: Simple, Adaptive-2D and Adaptive-3D. 3D combing utilizes a proprietary DPS algorithm to combine information from previous frames to eliminate residual subcarrier artifacts, such as cross luminance and cross chrominance. 3D combing can also be applied to non-composite sources, to clean up component video that was previously decoded from a composite source using lower-quality combing in other equipment. Combining the high-quality comb filter with DPS’ proprietary advanced 12-bit analog encoding provides maximum signal transparency and optimum transcoding.
The DPS-475 and DPS-575 also feature adjustable temporal and spatial digital noise reduction, as well as variable 2D filtering with separate horizontal and vertical bandwidth controls. Applying digital bandwidth filtering and noise reduction prior to MPEG encoding can improve overall MPEG performance through entropy reduction.
DPS' exclusive DigiDuplex mode provides bi-directional connectivity between analog tape machines and digital audio/video routing systems. DigiDuplex saves space and money by enabling digital to analog transcoding with simultaneous analog to digital frame synchronization - all in one compact box. In DigiDuplex mode, the unit's SDI video input is routed directly to the analog video outputs, which feed the inputs of an analog device. The analog output of the device can be simultaneously connected to the synchronizer's analog inputs, where it is processed and sent to the SDI video outputs. Conversion between digital and analog audio is handled in a similar fashion.
With the addition of the four-channel audio synchronizer module, the DPS-475 and DPS-575 can provide dual stereo audio and video synchronization in a single rack­unit-high package. The internal audio synchronizer option supports analog, AES/EBU
digital, and embedded SDI and DV audio I/O (with the DV I/O Module installed). All audio outputs are simultaneously active, which enables both analog and digital audio devices to be connected at the same time. All four audio channels can dynamically track the internal delay of the video synchronizer, and a fixed delay can also be specified, ensuring proper lip sync regardless of the program source. Audio test tones can be generated at operator-specified frequencies.
The DPS-475 and DPS-575 are more than just synchronizers. In addition to the features listed above, other functions include: Time Base Corrector, Audio Synchronizer, Digital Framestore with Linear Keyer, Digital Noise Reduction, DV Transcoder (optional), Video AGC, 10-bit Video Test Signal Generator with Zone Plate, Audio Test Signal Generator, VITS Inserter, Video Bandwidth Processor, Serial Digital Audio Embedder/De-Embedder and Animated Logo Inserter (optional). These functions can be accessed from the front panel, or from an optional DPS RC-475™ or RC-4000™ remote control.
The DPS-475 and DPS-575 represent ideal choices for broadcasters transitioning to DTV. When interfacing analog audio and video sources to serial digital equipment, nothing offers their flexibility, performance, reliability or economy.
This manual provides operating instructions for both the DPS-475 (NTSC) and DPS­575 (auto-switching NTSC/PAL). Differences between these two units are noted where applicable.

(these may be pre-installed on your unit)
Mounting
The size of the DPS-475 and DPS-575 allows them to fit into most standard consoles or 19-inch racks. If the unit is to be mounted in a rack, then the included rear support bracket must be used. Care must be taken to select a dry, well-ventilated location with a minimum of dust and vibration. Also, leave sufficient clearance from the unit’s sides to allow for proper air circulation.
After unpacking the unit and before installing it in a console or rack, allow at least 30 minutes for temperatures to equalize and to eliminate any condensation that may have developed.
Hardware Options
If you purchased hardware options such as the Audio Synchronizer Module, the Animated Logo Option, or the DV I/O module separately from the main unit, you will need to install them. Please see Appendix C for detailed instructions for installing your options safely and correctly.

CHAPTER 2: CONNECTIONS
This chapter describes the connections on the DPS-475 and DPS-575 used to interface the unit with other video and audio equipment in your system.
DPS-475AV/575AV: Back Panel
Breakout Cables
Some connections to the DPS-475/575 are provided on the supplied breakout cables. These breakout cables must be connected to the following ports on the back of the unit.
Multi-I/O Breakout Cable
This breakout cable, part number 774-753, connects to the DB-15F high-density connector labeled Multi I/O on the right side of the rear of the unit. This cable provides connections for RGB output, sync/key/auxiliary-composite output, S-Video output, and GPI.
AES/EBU Audio Breakout Cable [on audio-equipped units only]
This breakout cable connects to the DB-25F connector labeled AES/EBU on the rear of the unit. This cable provides connections for AES/EBU audio input and output. The standard AES/EBU Audio Breakout cable (part number 774-755) provides BNC connections; an optional Audio Breakout cable, part number 774-470, provides BNC and XLR connections.
Video Connections
The following are the video connections on the rear of the DPS-475/575, in left-to­right order, followed by those on the supplied breakout cable.
DV Input/Output
This 6-pin IEEE-1394 connector, labeled DV I/O, is used to connect DV (often referred to as “Firewire”) devices. In addition to carrying DV video and audio input and output, this port also provides DV device control, allowing control of the DV device directly from the DPS-475/575. This connection is active only if the optional DV I/O Module is installed.

S-Video Input
The 4-pin connector on the rear of the unit, labeled S-Video, is used for S-Video (Y/C) signals, such as from an S-VHS or Hi8 device. It is normally connected to the S-Video output of a playback VTR using a standard 4-pin to 4-pin S-Video cable. Some JVC ‘industrial’ type S-VHS players use a 7-pin connector for their S-Video output. To interface with such machines, a 7-pin to 4-pin adapter cable is required from the manufacturer of the VTR.
Component Analog V ideo Input
These three BNC connectors, labeled CAV-Y In, R-Y In, and B-Y In, are used to input the signals from analog component devices, such as Betacam® VTRs.
If component analog video input is not needed, the CAV-Y In connection can be reassigned as a second composite video input with the CAV-Y Composite option in the Video Setup menu (see Chapter 5, “Menus: Video Setup”).
Composite Video Input
This BNC connector, labeled Composite In, is used to feed composite 1 Vp-p 75Ω video to the DPS-475/575. In Synchronizer mode, the input video signal must be direct color or monochrome (such as from a satellite feed or live camera); in Timebase Corrector or auto switching mode, the input signal can be connected to the video output of a heterodyne source such as a camcorder or VTR.
Serial Digital Input
This BNC connector, labeled SDI In, accepts serial digital ITU-R BT.601 video and embedded audio data at a rate of 270 megabits per second.
Serial Digital Reclocked Output
This BNC connector, labeled SDI Reclocked, provides a digitally-regenerated copy of the SDI Input, with no processing applied.
Serial Digital Outputs
These BNC connectors, labeled SDI Out and SDI Out-2, provide the processed and synchronized serial digital ITU-R-BT.601 video and embedded audio, 270 megabits­per-second output.
Composite Video Output
These BNC connectors, labeled Composite Out and Composite Out-2, provide processed, synchronized/timebase-corrected versions of any of the input signals. If the unit is set to Bypass mode, the Composite Input is bypassed directly to the Composite
Out output (the left-most of the two connectors), providing an unprocessed signal. Composite Out-2 operates as normal (providing processed output from the selected
video input). The Composite Input is automatically bypassed to the Composite Out output when the unit is off.
Component Analog V ideo Output
These three BNC connectors, labeled CAV-Y Out, R-Y Out, and B-Y Out, provide processed, synchronized/timebase-corrected analog component video output.

Chapter 2:
Connections
Genlock Reference
These BNC connectors, labeled Genlock In and Genlock Loop, are used to loop a genlock signal through the unit to establish the timing for its video output signal. The signal for this input must always be stable, such as the output from a black-burst or color-bar generator. Do not attempt to use a signal that has not been timebase­corrected. When a valid signal is connected to the Genlock In input, the video output of the DPS-475/575 will be genlocked to this signal, and the Genlock LED will be on. When no external reference is supplied to the genlock input, the unit will operate using its own internal sync generator. If the Genlock Loop is unused, terminate it with a 75Ω terminator.
S-Video Output
(on breakout cable)
This 4-pin connector on the Multi-I/O breakout cable provides processed, synchronized/timebase-corrected S-Video (Y/C) output.
RGB(S) Video Output
(on breakout cable)
These four BNC connectors on the Multi-I/O breakout cable, comprising auxiliary Red, Green, Blue, and Sync, provide processed, synchronized/ timebase-corrected RGB(S) [RGB with auxiliary sync] video output. If RGB without auxiliary sync is sufficient, the Aux. Sync connection can be reassigned as an auxiliary Composite output. If RGB(S) output is not required, these outputs can be reconfigured to provide a key channel output.
Auxiliary Composite Output (on breakout cable)
The Aux. Sync connection on the Multi-I/O breakout cable, normally used for sync in RGB(S) [RGB with auxiliary sync] video output, can be reassigned to provide an auxiliary Composite video output with the Aux Sync/Comp option in the Video Setup menu.
Key Output (on breakout cable)
The Aux. Sync connection on the Multi-I/O breakout cable, normally used for sync in RGB(S) [RGB with auxiliary sync] video output, can be reassigned to provide a key channel output with the Aux Output option in the Video Setup menu.
Audio Connections
The DPS-475AV and DPS-575AV can process 2 stereo pairs of analog, AES/EBU, Serial Digital (SDI) or DV audio (with the optional DV I/O Module). The audio inputs can be selected from the front panel or Audio Setup menu, and the operator can specify which of the stereo channels are to be processed. All of the outputs are active simultaneously.
Analog Audio Inputs and Outputs
(Terminal Strips)
Two stereo pairs of analog audio input and output are supported, designated Channel 1 and Channel 2 on the rear of the unit. Each is comprised of a left and right
component. Each analog audio input channel can be configured as 600Ω or high­impedance. Each channel can be configured as balanced or unbalanced.
Two terminal strips (one for channel 1, one for channel 2) provide analog audio connections. Each terminal strip uses the following pinouts:
7
AES/EBU Inputs
(on Audio breakout cable)
Two BNC connectors (one for each of Channel 1 and 2) are provided on the standard Audio breakout cable (part number 774-755) for AES/EBU input.
An optional Audio breakout cable, part number 774-470, provides four connectors for AES/EBU input: two XLR (one for each of Channel 1 and 2), and two BNC (one for each of Channel 1 and 2). The XLR connectors are used for AES/EBU balanced audio input, while the BNC connectors are used for unbalanced AES/EBU input. Note that only two of the above input connections can be used at a time (one for Channel 1, and one for Channel 2), and they must be of the same type (XLR or BNC). The AES Source menu option selects between the XLR and BNC connections.
AES/EBU Outputs
(on Audio breakout cable)
Two BNC connectors (one for each of Channel 1 and 2) are provided on the standard Audio breakout cable (part number 774-755) for AES/EBU output.
An optional Audio breakout cable, part number 774-470, provides four connectors for AES/EBU output: two XLR (one for each of Channel 1 and 2), and two BNC (one for each of Channel 1 and 2). The XLR connectors are used for AES/EBU balanced audio output, while the BNC connectors are used for unbalanced AES/EBU output. Both BNC and XLR output is available concurrently.
Audio Delay Pulse/GPI Output (on Multi-I/O breakout cable)
The general-purpose GPI output, a BNC connection on the Multi-I/O breakout cable, can be configured for use as an audio delay pulse output, to be sent to an external audio delay box or synchronizer.
Serial Digital Embedded Audio Input (SDI)
The unit accepts four channels of embedded audio on the SDI input port. The four channels can be selected from any group on the SDI input.
Serial Digital Embedded Audio Output (SDI)
Any of the selected audio inputs can be embedded into the output of the SDI stream. The operator can select which group of four audio channels (of the 16 available in the SDI format) the output will be embedded into.
Remote Control Ports
In addition to GPI input (for remote triggering of functions such as Freeze) and output (for triggering external devices), all functions of the DPS-475 and DPS-575 can be remotely controlled by devices capable of either RS-232 or RS-422. Two additional remote control methods are supported: DPS Coaxial Network (DCN), for use with controllers such as the DPS RC-4000 and RC-475 Remote Control Systems, and 10BaseT Ethernet networking for control through a TCP/IP-based network. The type of control, and any appropriate parameters, are selected in the System Config menu, under the Remote Control sub-menu (see Chapter 12, “Menus: System Config”).

Chapter 2:
Connections
RS-232 and RS-422
This DB-9F connector, labeled RS-232/422 on the rear panel of the unit, is used to remotely control the DPS-475/575 via either RS-232 or RS-422. When this port is in use, a Unit Address must be set to an appropriate value in the range of 1-127 (see Chapter 12, “Menus: System Config”). This allows the unit to be used in a multi-drop configuration where only the unit addressed will respond to remote commands. The RS-232 port is also used for transferring files to the unit from a Microsoft Windows­based workstation via custom software (included). See Appendix D for information on transferring files from a Microsoft Windows system.
Ethernet Port
The 10BaseT Ethernet connector, labeled Ethernet on the rear of the unit, is used to connect the DPS-475/575 to a TCP/IP-based network for remote control and status monitoring. Control of the unit is then handled through web-browsing software or an RC-475 remote control panel. See Appendix F for details of controlling the unit from your web browser. Ethernet can also be used to control additional DPS-475/575 units from the front panel of this unit. When using Ethernet, the IP Address, Netmask, and Gateway settings of the unit must be configured for your network; your network administrator can provide you with these settings. These settings are located in the System Config menu, under the Remote Control sub-menu (see Chapter 12, “Menus: System Config”).
DCN Port
The BNC connector labeled DCN on the rear of the unit is used to provide a DCN (DPS Coaxial Network) interface for remote control and status monitoring. DCN is a proprietary network in which 75Ω coax is used as a multi-drop, bi-directional network. Using a BNC T-connector on the DPS-475/575, loop coax between each unit and the remote controller (such as the RC-4000 and RC-475). At each end of the chain, install a 75Ω terminator. Every DPS-475/575 is assigned a unique DCN address at the factory, so there is no software configuration required. Maximum cable length (total) in a DCN configuration should be limited to 2000 feet. DCN can also be used to control additional DPS-475/575 units from the front panel of this unit.
Use with RC-4000 and RC-475
DCN is used to control the unit from an RC-4000 remote control panel. The Search for devices menu option on the RC-4000 can be used to find all DPS devices attached
to it’s DCN port and configure itself to control them. This may be done for any number of units at one time. DCN also allows multiple RC-4000s to control a single DPS-475/575.
It is possible to remotely disable and enable the front panel of the DPS-475/575 from the RC-4000 using the “KeyLock” option. If this option is not activated, then it is possible for a local user to modify the remote-user’s settings from the front panel. However, the RC-4000 will periodically poll the device and show the new parameters if the local user changes them. If remote control is the usual case, then it is probably best to disable front-panel access once the device has been installed.
The RC-475 remote control provides an Ethernet port, which permits it to be conveniently connected to a TCP/IP network. For instructions on using the DPS RC­475 remote control, please see the RC-475 manual.
For use with the DPS-475/575, the RC-4000 must have firmware version 1.3c or higher. Note that not all functions of the DPS-475/575 will be accessible through the RC-4000 remote control.
9
GPI Inputs (on Multi-I/O breakout cable)
Two RCA-jack GPI inputs are provided on the Multi-I/O breakout cable. These allow a GPI-based external controller to trigger functions of the unit such as Freeze. The function triggered by each GPI input is configured in the System Config menu, under the Misc. Setup sub-menu (see Chapter 12, “Menus: System Config”).
GPI Output (on Multi-I/O breakout cable)
A user-configurable general-purpose BNC output is provided on the Multi-I/O breakout cable This output can be used for feeding an audio delay pulse to an external audio synchronizer, or can be configured as a GPI output to trigger external devices. The functionality of this output is configured with the GPO Output option in the System Config menu (see Chapter 12, “Menus: System Config”).

Menu options, selections, and feedback are shown on the Vacuum Fluorescent Display (VFD) display panel. When the unit is first powered-up, the display will first show the DPS logo and product information, which will then be replaced by the Idle Screen:
The Idle Screen is a real-time status screen which provides feedback about various parameters of the currently selected inputs. The Idle Screen is shown when the user is not adjusting parameters or browsing the menus.
The first three lines of the Idle Screen provide real-time feedback of the Luma, Black, and Chroma levels of the currently selected video input source.
On DPS-475AV and DPS-575AV units , and DPS-475 and DPS-575 units that have the Audio Synchronizer Module installed, the next two lines of the display show real­time feedback of the channel 1 and 2 audio input levels.
On units with the DV I/O Module installed, the bottom line of the Idle Screen displays the current DV Time Code reported by the connected DV device, and just to the left of this, the current DV transport state.
The Machine Name specifed in the System Config menu (see Chapter 12) is also shown on the Idle Screen. On units without DV or audio capability, the Idle Screen will display the current measured video delay through the unit.
Note that at regular intervals, the display will “invert” itself. In the initial state, text and information appears lit, over an “unlit” background. In the inverted state, the background will be lit, with the text and information appearing “unlit” (black). THIS PERIODIC INVERSION IS NORMAL; it does not indicate any kind of problem nor status. The inversion is done to preserve the lifespan of the display panel (leaving the display in a single state can cause display pixels to burn out prematurely).
Resetting the Unit
In the Video Input Selection section of the front panel, just to the right of the CAV and SDI indicators, is a small hole. This hole provides access to the RESET button, which will reset the DPS-475/575 unit. This is equivalent to power-cycling the unit.
Menu Controls
All options and parameters for the DPS-475/575 are accessed through configuration menus, which appear on the display panel. Selecting and using any of the menu and sub-menu options follows the same general procedure. See Chapter 4, “Menu Overview and Feature Cross-Reference,” for a chart of the menu structure.
Moving Through the Menus
1. With the Idle Screen displayed, press the Enter button. (If the Idle Screen is not displayed, press Exit repeatedly until it is.) The display panel will show the Main Menu options.
12
DPS-475/575 Service Manual
Chapter 3:
Operation - Front Panel Controls
2. Scroll through the list using the control knob, until the desired sub-menu is highlighted. Press the Enter button to enter the sub-menu.
3. Use the control knob and Enter button to choose and activate the option you want. If there are further sub-menus, use the procedure in step 2 to select between them, and to select the option you wish to change.
Pressing the Exit button while in a menu or sub-menu will return you to the previous sub-menu, or if you are at the Main Menu, to the Idle Screen.
Changing Parameters
Once you have selected the option you wish to change, use the control knob to set the new value for the parameter. When setting parameters that have discrete value options (such as selecting Field, Frame, or Strobe mode), the control knob will cycle through the valid settings.
For parameters which have a numerical range of values, the display will show both a numeric and a visual representation of the range, and the control knob can be used to set the new value.
Note that adjustments affect the output immediately as the knob is turned.
When setting parameters with a numerical range of values, you can switch the control knob between Fine and Coarse adjustment mode. When you first enter the parameter adjustment screen, the control knob is in Fine mode. Pressing the Enter button switches to Coarse adjustment mode, and the Enter button lights up. This allows you to make large adjustments more quickly. Pressing Enter again returns the control knob to Fine mode.
For example, when setting a parameter, the control knob may adjust the value in increments of 0.02 while in Fine Mode, and 0.50 in Coarse mode.
Pressing the Default button will reset the configuration parameter to its default values. The Default button will be lit whenever the current value of the parameter is equivalent to the default value, whether you reached this value by pressing the Default button, or scrolling to it with the control knob.
Press the Exit button to accept your new value, and return to the previous menu or sub-menu.
Remote Control
By placing the DPS-475/575 in Remote mode, you can control additional DPS­475/575 units on the same DCN or Ethernet network from the front panel of this unit.
Pressing the Remote front-panel key will bring up a list of available units that can be controlled. <local device> will always be an option on this list, representing the unit you are physically using. Use the control knob to scroll through the list of available devices and highlight the unit you wish to control, then press the Enter button to activate it. Selecting <local device> exits Remote mode, resuming normal single-unit operation.
Once you have selected a remote unit to control, all front-panel features operate as if you were actually at the front panel of that remote unit. The VFD display, status indicators and button lights all reflect the status of the remote unit; all buttons and controls, with the exception of the Remote key, control the remote unit, not the one you are physically operating. To stop controlling the remote unit, use the Remote key to select a new unit (or the local device) to control.
The light on the Remote key flashes while the unit is remotely controlling a device.
13
Status Indicators
The status indicator lights provide visual feedback on the current mode and operating conditions of the unit.
Genlock
This light indicates the current status of the external genlock source. If the unit is configured to Auto Genlock mode, this indicator will be lit as long as a stable genlock source is connected to the unit. If no genlock source is present, the unit will automatically switch to Internal Genlock mode, and this indicator will flash.
If the unit is configured to Internal Genlock mode, it will operate on its own internal crystal, and this indicator will be unlit.
EDH
This light indicates the current configuration and status of Error Detection Handling (EDH) in the input Serial Digital video stream. This indicator is unlit when EDH Detection is turned off in the unit.
This indicator will flash briefly when EDH Detection is enabled and EDH errors have been detected and not yet cleared by the operator. The actual count of these errors is reported in the EDH Error Count menu option.
TBC
This light indicates whether or not the composite input signal is being time base corrected by the unit’s TBC circuitry. If the unit is in Synch mode, the internal TBC is not active, and this indicator will be off. If the unit is in TBC mode, the unit will time base correct the input signal (generally for heterodyned signals from sources such as a VTR), and this indicator will be lit. If the unit is in Auto-Switch mode, the unit will sense the incoming composite video signal and select between Synch and TBC modes automatically; in this mode, the indicator will flash when the TBC is active.
Autotrack
This light indicates whether or not the audio Auto Track mode is enabled. When enabled, this indicator will be lit, and the unit will automatically delay the audio data to match the delay of the video data through the synchronizer (up to 4 fields). This indicator will be off when Auto Track is disabled.
DigiDuplex
This light indicates whether or not the unit is in DigiDuplex mode. In DigiDuplex mode, the indicator is lit, and the unit’s SDI video input is routed to the analog video outputs, while the selected analog video input is simultaneously synchronized and sent to the SDI output. With an audio-equipped unit, conversion between digital and analog audio is handled in similar fashion, simultaneously with the video. This indicator is unlit when DigiDuplex mode is off. See Appendix E, “DigiDuplex Mode”, for a detailed explanation of DigiDuplex mode and its settings.
Option
This light indicates the status and/or configuration of the currently installed option card module (if any). The meaning of this indicator varies depending on the particular option installed; please see the documentation for your option module for further details.

Chapter 3:
Operation - Front Panel Controls
Video Input Selection
The current (active) video input format selection is shown by these indicator lights. The current input is selected by pressing the Video In button until the desired input LED becomes lit. Selectable inputs are:
• Comp (Composite)
• S-Video
• CAV (Component Analog Video)
• SDI (Serial Digital)
With the optional DV module installed, DV will also be selectable as an input.
If an option card module is installed that includes an additional video input, it will be selectable as Option.
If no input signal is present on the selected video input, the corresponding indicator light will flash.
Audio Input Selection
On DPS-475AV and DPS-575AV units, and DPS-475 and DPS-575 units with the Audio Synchronizer Module installed, the current (active) audio input format selection is shown for each channel by these indicator lights.
Pressing the Audio In button takes you to a menu for selecting the Channel 1 audio input; this is the same as the Ch1-Input menu option. Pressing the Audio In button a second time takes you to a menu for selecting the Channel 2 audio input; this is the same as the Ch2-Input menu option.
Selectable audio inputs are:
• Analog
• AES/EBU
• SDI Embedded
With the optional DV module installed, DV will also be selectable as an input. If an option card module is installed that includes an additional audio input, it will also be selectable.
The selection menus also provide access to two “special” audio modes:
• Mute disables audio output; while in this mode, all input source indicator lights for that channel will be on.
• Test Tones outputs audio test tones from the unit. The parameters of the test tones (Level, Frequency) are set from the Audio Setup menu (see Chapter 6, “Menus: Audio Setup”). While in Test Tones mode, all input source indicator lights for that channel will flash.
If AFV (Audio-Follows-Video) mode is enabled through the audio menus (see Chapter 6, “Menus: Audio Setup”), the AFV indicator for that channel will be lit. In this mode,
15
each of the selectable video inputs has an audio input selection linked to it. Whenever the video input selection is changed, the audio input selection for any AFV-enabled channel automatically changes correspondingly.
• You can override AFV mode by manually selecting a different audio input even when AFV is enabled. This does not, however, turn AFV mode off; the next time the video input selection is changed, the audio will again follow it. AFV mode can only be disabled through the audio menus.
• The AFV link to each of the video inputs is set through the Audio Setup menu (see Chapter 6, “Menus: Audio Setup”).
The input selection for channels 1 and 2 cannot be selected independently if 96 kHz AES Output mode (see Chapter 6, “Menus: Audio Setup”) is enabled; they must then always be set to the same input source.
When Dolby-E (Data) Mode is enabled (see Chapter 6, “Menus: Audio Setup”), the audio input selection for channel 1 is locked to AES/EBU, and only this channel supports Dolby-E Data. SDI Embedded Audio cannot be used while in this mode.
Pressing and holding the Audio In button for one second will take you to the Audio Setup menu (the same as is available through the Main Menu), from which you can set additional audio configuration options.
When one input channel is being routed to both output channels through the Channel In->Out or Aud Follows Vid menu options (see Chapter 6, “Menus: Audio Setup” for details), only that input channel’s LED will be lit to indicate the audio input source.
On DPS-475 and DPS-575 units without audio capability, the Audio In button is user­programmable; that is, the user can assign the button to a desired menu function. See the “User-Programmable Keys” section later in this chapter for instructions on assigning this button to a menu function.
Freeze Controls
The freeze controls provide instant access to freezing individual frames or fields of the incoming video source, strobing the incoming video, or performing a 3:2 pulldown on the input source.
Pressing the Frz Mode button takes you to a menu setting for selecting which freeze mode will be applied to the incoming video. This is the same as the Freeze Mode menu option under the Video Setup menu.
Pressing the Frz Mode button multiple times will cycle through the different modes, or the control knob can be used for selection. The available modes are:
• Frame - freezes an entire frame of the incoming video
• Field - freezes a single field of the incoming video
• Strobe - strobes the incoming video
• Film - applies a 3:2 pulldown to the incoming video, effectively giving
a simulated 24fps look to the video output
Pressing the Take button activates the selected freeze mode and applies it to the incoming video. The light on the Take button will flash while freeze mode is active. Press Take again to return to the live video feed.
16
DPS-475/575 Service Manual
Chapter 3:
Operation - Front Panel Controls
• If Field freeze mode is selected, the display panel will indicate which field of the video is frozen (1, 2, 3, or 4). This will initially be the same as the value of the Field Select menu option; the control knob changes the currently selected field (and the Field Select menu option is updated accordingly).
• If Strobe freeze mode is selected, the display panel will indicate the current strobe rate (number of frames per update) applied to the incoming video (1 to
255). This will initially be the same as the value of the Strobe Rate menu option; the control knob changes the rate (and the Strobe Rate menu option is updated accordingly).
• Pressing the Frz Mode button while Frame or Field freeze mode is already active will toggle between Frame and Field freeze mode.
• The Mute In Freeze audio menu option (see Chapter 6, “Menus: Audio Setup”) specifies whether or not audio output will be muted while the video is frozen in Frame or Field mode.
Mode Selection
The mode selection controls provide direct access to Bypass, Test Signal Generator, Keyer, and Noise Reduction functions.
Bypass
The Bypass key toggles between Process and Bypass mode. The Bypass key must be held in for one second to activate Bypass mode; a normal press will return to Process mode.Process mode is the normal mode of operation. In Bypass mode, no processing is applied to the Composite In video signal; it is passed directly to Composite Out. Similarly, in Bypass mode, no processing is applied to the analog and AES/EBU audio inputs; they are routed directly to the outputs.
The light on the Bypass button flashes while the unit is in Bypass mode.
Composite In and the analog and AES/EBU audio inputs are also bypassed when the power to the unit is off.
TSG
The TSG key sets the unit to Test Signal Generator mode. Pressing the TSG key activates the Test Signal Generator, sending the currently selected test pattern to all video outputs. This will initially be the test pattern selected in the TSG: menu option of the Video Setup menu. When TSG mode is active, the light on the TSG button flashes, and the display panel shows a list of available test patterns (and indicates which one is active); you can change the displayed pattern by scrolling through the list with the control knob, and pressing the Enter key to select a new pattern.
Pressing the TSG key again returns the outputs to the incoming video feed.
Keyer
The Keyer button provides access to the unit’s linear keyer. Pressing the Keyer button once takes you directly to the Keyer Setup menu, from which you can enable the keyer, and configure the keyer settings.
If a file (animation or still) to be displayed has been selected previously, pressing the Keyer button a second time will fade in the animation or still over the live video; pressing the Keyer button a third time will fade it back out. Note that if it is an
17
animation being keyed, the animation will fade out automatically after the number of repetitions specified in the Repeat option of the keyer settings, if not faded out manually first.
If no file has been previously selected, pressing the Keyer button a second time takes you to the keyer’s file selection list (equivalent to the File option of the Keyer Setup menu), from which you can select a file from among the still images and animations stored in the unit. These images could have been uploaded to the unit from a PC (see Appendix D, “The Uploader Software” and Appendix F, “Ethernet Control”) or grabbed from video from the TSG/Image Grabbing menu.
The image or animation to be displayed or keyed is selected by scrolling through the list with the control knob, and pressing the Enter key to select the desired file. The file will be loaded, and you will be returned to the Keyer Setup menu. Pressing the Keyer button again will fade in the file, and a subsequent press will fade it back out.
The light on the Keyer button will flash while the key is in transition (fading in or fading out), and be lit while the key is being displayed.
See Chapter 7, “Menus: Keyer Setup” for more information about the Keyer Setup menu.
N/R
Pressing the N/R button accesses the noise reduction functions of the unit. Pressing the N/R button once takes you directly to the Noise Reduction menu, from which you can configure noise reduction settings. See Chapter 8, “Menus: Noise Reduction” for a detailed description of the Noise Reduction menu.
Pressing the N/R button subsequent times toggles the noise reduction features on and off. The light on the N/R button will be lit when noise reduction is enabled.
Proc Amp Controls and User Keys
The proc amp controls allow the modification, storing, and recalling of proc amp settings.
Automatic Proc Amp Setup (“Gimme Bars”)
The luminance gain, black level, chrominance gain and hue can all be automatically set by the unit based on incoming SMPTE bars.
To use the “Gimme Bars” automatic setup mode, SMPTE bars (or other 75% bars) must be supplied to the currently selected video input. Press and hold the Luma button; the four proc amp parameters are automatically adjusted.
Luma
Pressing the Luma button allows you to adjust the luminance gain by using the control knob and menu controls (see the Menu Controls section earlier in this chapter). This is equivalent to the Luma Gain menu option in the Video Setup menu.
While setting the luminance gain, the display panel will also show the maximum luminance level (in IRE or mV) of the incoming video signal.
Valid Range: -99.99 dB to 6.00 dB (Y/C, SDI, DV)
-8.01 dB to 4.04 dB (Composite, CAV)

DPS-475/575 Service Manual
Chapter 3:
Operation - Front Panel Controls
User-Programmable Keys
Many of the front-panel keys on the DPS-475/575 are user-programmable; that is, you can program them to take the user to a menu or specific function of your choice.
On all units, the User 1, User 2, and Hue keys are user-programmable. On units that do not have audio capability, the Audio In key is also programmable. On units in which an added option board does not require the Option key to be used, it can be programmed as well.
Of these keys, only the Hue key has a default function. If the user presses one of the other keys before it is programmed, the following message appears on the display panel:
This key has not yet been assigned a function. To program it, select the desired menu or setting that you wish to assign to it, using the normal menu controls. Then press and hold this key for five seconds.
Whether a programmable key already has a function assigned to it or not, it is easy to reprogram the key. Holding down a programmable key for five seconds will assign to it whatever menu or option is currently displayed on the display panel.
For example, to assign the User 1 key to adjust the video AGC Bias, select the AGC Bias option from the Video Setup menu as normal. With the AGC Bias adjustment screen displayed, press and hold the User 1 key for approximately five seconds. All LED’s on the unit will then flash once to indicate successful programming. If programming fails for any reason (for example, if you attempt to program a button to the Idle Screen), all LED’s on the unit will flash three times quickly. Note that if the programming fails, any function previously assigned to that key will have been erased, so the key will have to be reprogrammed.
Programmable keys can be assigned to jump to menus (at a specified point, if desired) in a similar fashion.
Once the key has been programmed, pressing it will jump to the menu or option assigned to it. Pressing it again while already at that screen will cycle through the values (if the key is assigned to an option) or select the active menu choice (if the key is assigned to a menu).
In our above example, pressing the User 1 key will now take the user to the AGC Bias adjustment screen. Each additional press of the User 1 key will cycle through the allowed adjustment values.
Power-Up Keys
Certain special functions of the DPS-475/575 are accessed by holding down specific front panel keys while turning on the unit.
Force Firmware Download
Holding down the Enter key while turning on the unit will force the unit into Firmware Download mode.
Under normal circumstances, the unit will automatically enter Firmware Download mode whenever the Windows-based Uploader software attempts to upload a firmware upgrade file to the unit. (see Appendix D, “The Uploader Software”). However, if the
21
firmware within the unit becomes corrupted (possibly during a failed firmware upgrade), the unit may not start up properly, and thus would be unable to automatically enter Firmware Download mode. Using this power-up key will allow you to upload new firmware to the unit from the Uploader software.
Self-Test Mode
Holding down the Bypass key while turning on the unit will force the unit into Self­Test mode. Self-Test mode will allow the operator to test the front-panel controls and indicators of the unit. The display panel will indicate which particular controls and indicators are being tested.
When testing buttons, each press of a button will be reported on the display panel, with the name of the button. Turning the control knob ends the testing of buttons.
When testing LEDs, each column of indicators on the buttons will light consecutively left-to-right. Each row of indicators on the buttons will then light consecutively top­to-bottom. The columns and rows of the stand-alone indicators will follow the same pattern, and the process will repeat. Press any button to end the testing of LEDs.
When testing the control knob, each turn of the control knob is reflected in a numeric value shown on the display panel. Pressing any button ends the testing of the control knob, and begins the testing of buttons again.
To exit Self-Test mode, the unit must be turned off and back on, or reset using the Reset Button.
Erase Firmware
Holding down the Keyer key while turning on the unit will erase all FPGA and firmware files from the unit’s memory. This will have to be done if you are attempting to upgrade the unit’s FPGA’s or firmware, but there is not enough available memory to upload the new file. WARNING: after performing this
operation, replacement FPGA and firmware files must be uploaded to the unit before the unit will be operational again.
Factory Reset
Holding down the Memory key while turning on the unit will perform a factory reset by clearing the unit’s non-volatile memory. WARNING: all configuration options
will be reset to factory defaults. All saved settings presets will be lost.

Menu Overview and Feature Cross-Reference
CHAPTER 4: MENU OVERVIEW AND F
EATURE CROSS-REFERENCE
Menu Controls
All options and parameters for the DPS-475/575 are accessed through configuration menus, which appear on the display panel. The menus of the DPS-475 and DPS-575 are organized into eight main functional areas:
• Video Setup
• Audio Setup (on audio-equipped units only)
• Keyer Setup
• Noise Reduction
• DV Control (on units with DV I/O Module only)
• Timing Setup
• TSG/Image Grabbing
• System Config
Moving Through the Menus
Selecting and using any of the menu and sub-menu options follows the same general procedure.
1. With the Idle Screen displayed, press the Enter button. (If the Idle Screen is not displayed, press Exit repeatedly until it is.) The display panel will show the Main Menu options.
2. Use the control knob to select one of the sub-menus listed in the main menu. To do so, scroll through the list using the control knob, until the desired sub-menu is highlighted. Press the Enter button to enter the sub-menu.
3. Use the control knob and Enter button to choose and activate the option you want. If there are further sub-menus, use the procedure in step 2 to select between them, and to select the option you wish to change.
Pressing the Exit button while in a menu or sub-menu will return you to the previous sub-menu, or if you are at the main menu, to the Idle Screen.
Changing Parameters
Once you have selected the option you wish to change, use the control knob to set the new value for the parameter. When setting parameters that have discrete value options (such as selecting Field, Frame, or Strobe mode), the control knob will cycle through the valid settings.
23
For parameters which have a numerical range of values, the display will show both a numeric and a visual representation of the range, and the control knob can be used to set the new value.
Note that adjustments affect the output immediately as the knob is turned.
When setting parameters with a numerical range of values, you can switch the control knob between Fine and Coarse adjustment mode. When you first enter the parameter adjustment screen, the control knob is in Fine mode. Pressing the Enter button switches to Coarse adjustment mode, and the Enter button lights up. This allows you to make large adjustments more quickly. Pressing the Enter button again returns the control knob to Fine mode.
For example, when setting the a parameter, the control knob may adjust the value in increments of 0.02 while in Fine Mode, and 0.50 in Coarse mode.
Pressing the Default button will reset the configuration parameter to its default values. The Default button will be lit whenever the current value of the parameter is equivalent to the default value, whether you reached this value by pressing the Default button, or by scrolling to it with the control knob.
Press the Exit button to accept your new value, and return to the previous menu or sub-menu.

In TBC mode, generally for heterodyned signals from sources such as a VTR, the unit will time base correct the composite input signal. The TBC indicator on the front of the unit will be on.
In Auto-Switch mode, the unit will sense the incoming composite video signal and select between Synch and TBC modes automatically as required. In this mode, the TBC indicator will flash when the TBC is active.
The TBC is always used for S-Video input, independent of this setting.
3D Comb Decoder
Configures the operation of DPS’ proprietary 12-bit adaptive 3-dimensional comb filter decoder. This option selects between adaptive 2D and adaptive 3D combing, and for 3D combing, whether to comb luminance, chroma, or both. 3D combing combines information from previous frames in order to cancel eliminate residual subcarrier artifacts such as cross luminance and cross chroma.
3D combing can be utilized even for non-composite input signals. For example, if the component input video source was decoded from composite by a less sophisticated decoder, the 3D comb filter in the DPS-475/575 can be used to clean up the signal and remove cross luminance and chroma artifacts.
Valid Settings: Disable, Luma, Chroma, Both Y+C
Default Setting: Both Y+C (525-line mode)
Luma (625-line mode)
Related Settings: Temporal NR-Luma, Temporal NR-Chroma,
3D Chroma Motion Bias
When set to Disable, 3D combing is disabled; adaptive 2D combing is used.
The Luma and Chroma settings enable 3D adaptive combing on luminance and chrominance, respectively, while Both Y+C enables 3D adaptive combing on both.
Under normal circumstances, Both Y+C will be the desirable 3D combing mode. It is not possible, however, to use both Temporal Noise Reduction and 3D combing on the same channel simultaneously. (For example, if Temporal NR-Luma is enabled, 3D combing of luminance is not possible, so the 3D comb decoder must be disabled or set to Chroma.) This is not a problem; with a sufficient Temporal Noise Reduction setting, there would be no benefit to using the 3D comb filter simultaneously.
Setting this option to Luma or Both Y+C automatically disables Temporal NR-Luma (sets it to 3D Comb mode). Similarly, setting this option to Chroma or Both Y+C automatically disables Temporal NR-Chroma (sets it to 3D Comb mode).
This setting will be automatically changed accordingly (disabling 3D combing on luminance and/or chrominance) when Temporal NR-Chroma and/or Temporal NR- Luma are enabled by the user.
See Chapter 8, “Menus: Noise Reduction” for more information on the Temporal Noise Reduction settings.
3D Chroma Motion Bias
Adjusts the algorithm of the adaptive 3D comb decoder to compensate for high­motion, color-intensive footage.
Valid Settings: Low, Normal, High, Extreme
35
Default Setting: Normal (525-line mode)
Low (625-line mode)
Related Setting: 3D Comb Decoder, Comb Decoder
The Normal setting should be ideal for most applications. If chroma lag is visible in footage that contains color-intensive, high-speed motion, the Low setting should be used. The High and Extreme settings may be useful when processing images with little or no motion, to provide the highest level of cross-color reduction .
Comb Decoder
Selects the mode of the comb filter decoder, between notch filtering and adaptive combing.
Valid Settings: Notch, Adaptive
Default Setting: Adaptive
Related Setting: 3D Comb Decoder, 3D Chroma Motion Bias
The 3D Comb Decoder option detailed earlier in this section specifies whether adaptive combing will be 2D or 3D.
DigiDuplex Mode
Enables or disables DigiDuplex mode. When enabled, the DigiDuplex indicator on the front panel is lit, and the unit’s SDI video input is routed to all analog video outputs, while the selected analog video input is simultaneously synchronized and sent to the SDI output. With an audio-equipped unit, conversion between digital and analog audio is handled in similar fashion, simultaneously with the video.
Valid Settings: Disable, Enable
Default Setting: Disable
Related Settings: DDPlex Gain-R, DDPlex Gain-L, Digiduplex Input,
DDPlex AES/EBU Out (all in Audio Setup menu)
The video input selection front-panel controls and menu option specify the analog video input which will be synchronized and sent to the SDI output. Thus, SDI is not a valid video input selection while in DigiDuplex mode. If the user enables DigiDuplex mode while the currently selected video input is SDI, the video input selection will automatically be changed to Composite.
The audio input selection front-panel controls and menu option specify the audio input (analog, AES/EBU, SDI, Test Tones, or Mute) which will be synchronized and sent to the digital audio outputs (SDI Embedded and/or AES/EBU). Note that in DigiDuplex mode, audio input selection for channels 1 and 2 are locked together, and must have the same input format. The Digiduplex Input option of the Audio Setup menu determines which digital input (AES/EBU or SDI) will be fed to the analog outputs. Audio configuration for DigiDuplex mode is controlled through the Audio Setup menu (see Chapter 6, “Menus: Audio Setup”).
DigiDuplex mode cannot be enabled when the Dolby-E (Data) Mode is enabled in the Audio Setup menu. If DigiDuplex mode is already enabled, it will be automatically disabled if Dolby-E (Data) Mode is then turned on in the Audio Setup menu.
See Appendix E, “DigiDuplex Mode”, for a detailed explanation of DigiDuplex mode and its settings.

Chroma Pairing Filter [DPS-575 Only]
Controls the degree of filtering of chroma line pairing artifacts. This option is only available in 625-line mode [PAL], and is only active when the unit’s TBC is active. This option has no effect when the unit is in 525-line mode or the TBC is not in use.
Valid Settings: Off, Norm, Max
Default Setting: Norm
The Norm setting should be ideal for most situations, while the Max setting should be used in cases of severe chroma line pairing artifacting.
NOTE: Users familiar with the DPS-470 (the predecessor to the DPS-475 and DPS-
575) may notice that the SDI Edge Insertion option available on the DPS-470 is not configurable on the DPS-475/575. SDI Edge Insertion is present in the DPS-475/575, and is always enabled. “Blanking-to-setup” level transitions are dynamically added by the unit based on the current input video signal levels. If the input signal lacks setup (for example, super-black), no unnecessary transitions are generated. If the input signal has setup, correctly shaped edges are added to conform with RS-170A specifications (140ns rise time).

CHAPTER 6: MENUS: AUDIO SETUP
Channel 1 Only, Channel 2 Only, Both Channels
The Channel 1 Only and Channel 2 Only sub-menus of the Audio Setup menu contain the same option settings, and differ only in which channel the settings affect. For example, the Channel 1 Only sub-menu contains the option Ch1-Input, while the Channel 2 Only sub-menu contains the option Ch2-Input. These perform the same function, selecting the audio input, for their respective channels. The functions of these options will be documented only once each below (following the example above, as Input). The Both Channels sub-menu is simply a concatenation of the Channel 1 Only and Channel 2 Only sub-menus, allowing you access to options for each channel from a single menu.
These settings affect the channel specified in the prefix of the option, Ch1 or Ch2, in the audio menus.
Input
Selects which audio input source is active.
Valid Settings: Analog, AES/EBU, SDI, DV*, Option*, Mute, Test Tones
Default Setting: Analog
Related Setting: 96 kHz AES Output

Mute disables audio output; Test Tones outputs audio test tones from the unit. The parameters of the test tones (Level, Frequency) are set in the Tone Level, Test Freq-L, and Test Freq-R options detailed later in this section.
If AFV (Audio-Follows-Video) mode is enabled, changing the Input setting performs a one-time override of AFV mode; the next time the video input selection is changed, the audio will again follow it.
The Input selection for channels 1 and 2 cannot be selected independently if 96 kHz AES Output mode (detailed later in this chapter) is enabled; they must then always be set to the same input source.
When Dolby-E (Data) Mode is enabled (see Chapter 6, “Menus: Audio Setup”), the audio input selection for channel 1 is locked to AES/EBU, and only this channel supports Dolby-E data. SDI Embedded Audio cannot be used while in this mode.

The AFV-<format> options specify which audio input the channel will automatically switch to when the video input selection is changed to that video <format>. (For example, the AFV-SDI option specifies which audio input will be switched to when the video input selection is changed to SDI).
Valid Settings: Off, Analog, AES-EBU, SDI, DV*, Option*, Mute,
Test Tones, Chan 1 or Chan 2
Default Setting: Analog
Related Setting: Aud Follows Vid
* DV and Option settings will only be available if the corresponding hardware module is installed.
If this option is set to Off, the audio input selection will NOT change when the video input selection is changed to the specified format; it will remain at its current selection.
Mute disables audio output; Test Tones outputs audio test tones from the unit. The parameters of the test tones (Level, Frequency) are set in the Tone Level, Test Freq-L, and Test Freq-R options detailed earlier in this section.
When this option is being set for channel 1, Chan 2 will be listed as an option; when this is selected, the audio input selection for channel 1 will switch to match that of channel 2 when the video input selection is changed to the specified format. When this option is being set for channel 2, Chan 1 will be listed as an option; when this is selected, the audio input selection for channel 2 will switch to match that of channel 1 when the video input selection is changed to the specified format. This overrides the swapping of channels with the Channel In->Out option.
For example, if AFV-Composite is set to Analog, the audio input selection for this channel will automatically switch to Analog when the video input selection is changed to Composite.
These settings are ignored when AFV (Audio-Follows-Video) mode is disabled (i.e. Aud Follows Vid is set to Off).
Global Audio Config
The settings in the Global Audio Config sub-menu affect BOTH audio Channel 1 and Channel 2 of the DPS-475 and DPS-575.

Note that the total audio delay will be the sum of the Auto Track delay, and any delay specified in the Fixed Delay option detailed earlier in this chapter.
The Autotrack indicator on the front panel of the unit will be lit when this option is enabled.
Master Mute
When enabled, this option mutes all of the audio output channels.
Valid Settings: Off, On
Default Setting: Off
Audio Bypass
Toggles between bypassing and processing the analog and AES/EBU audio inputs.
Valid Settings: Process, Bypass
Default Setting: Process
Process mode is the normal mode of operation. In Bypass mode, no processing is applied to the analog and AES/EBU audio inputs; they are bypassed directly to the outputs.
The analog and AES/EBU audio inputs are also bypassed when the power to the unit is off.
This setting is overridden by the master Bypass key on the front panel of the unit. If the front panel is used to select the master Bypass mode, the analog and AES/EBU audio inputs will be bypassed regardless of the setting of this option.
AES Data Grade

96kHz AES Output
Enables or disables 96 kHz AES/EBU output mode.
Valid Settings: Disable, Enable
Default Setting: Disable
Related Setting: Sample Rate, Input, Fixed Delay
A number of restrictions apply when this option is enabled:
• The Sample Rate setting is forced to 48 kHz.
• The audio Input source for channels 1 and 2 cannot be selected independently; they must always be the same input source.
• If the audio Input selection is set to AES/EBU, the system will use a 96 kHz sampling rate, thus providing 96 kHz input and output. While using this 96 kHz sampling rate, only AES/EBU outputs are active; all other outputs are muted. The use of the 96 kHz sampling rate results in the maximum valid value of the Fixed Delay option (detailed earlier in this chapter) being reduced.
• If the audio Input selection is set to anything other than AES/EBU, the system will use the 48 kHz sampling rate, and up-sample to 96 kHz for the AES/EBU output. All other outputs remain at 48 kHz.
Digiduplex Input
Specifies which digital audio input source (SDI Embedded or AES/EBU) will be transcoded to the analog audio outputs when the unit is in DigiDuplex mode. If the DDPlex AES/EBU Out option is set to Transcode, this is also the source that will be fed to the AES/EBU outputs.
Valid Settings: SDI, AES-EBU
Default Setting: SDI
Related Setting: DigiDuplex Mode (Video Setup menu),
DDPlex AES/EBU Out
See Appendix E, “DigiDuplex Mode”, for a detailed explanation of DigiDuplex mode and its settings.
DDPlex AES/EBU Out
Specifies the source for the AES/EBU outputs when the unit is in DigiDuplex mode.
Valid Settings: Transcode, Sync
Default Setting: Sync
Related Setting: DigiDuplex Input, DigiDuplex Mode (Video Setup
menu)
When this option is set to Transcode, the source of the AES/EBU outputs in DigiDuplex mode is the digital audio input which has gone through the transcoder, and is also being sent to the analog outputs. This input could be either SDI Embedded or AES/EBU audio, determined by the DigiDuplex Input setting detailed earlier in this section.
When this option is set to Sync, the source of the AES/EBU outputs in DigiDuplex mode is the selected audio input which has gone through the synchronizer.
53
CAUTION: If this option is set to Transcode, and the SDI Embedding option has been disabled (thus disabling the embedding of audio into the SDI stream), the selected audio input which has gone through the synchronizer will not be present on any of the audio outputs.
See Appendix E, “DigiDuplex Mode”, for a detailed explanation of DigiDuplex mode and its settings.
SDI Out
Selects which four channels of the SDI video output the unit’s four audio streams (left and right of channels 1 and 2) will be embedded into. This setting will be ignored if the SDI Embedding option is off.

1-1 / 1-2 routes input channel 1 to both output channels.
2-1 / 2-2 routes input channel 2 to both output channels.
1-2 / 2-2 routes input channel 1 to output channel 2, and input channel 2 to output
channel 1, thus swapping the output channels.
When one input channel is being routed to both output channels, only that input channel’s LED will be lit to indicate the audio input source.
This setting is overriden if Aud Follows Vid (detailed earlier in this chapter) is enabled, and the current video input source is AFV-linked to Chan 1 or Chan 2 (which will re-route the channel settings).
Sample Rate
Adjusts the sampling rate of the audio input.
Valid Settings: 48 kHz, 44.1 kHz, 32 kHz
Default Setting: 48 kHz
Related Settings: Test Freq-L, Test Freq-R, Fixed Delay,
96 kHz AES Output
As the SDI specification requires 48 kHz audio, this option must be set to 48 kHz for SDI audio embedding to work. If the sample rate is set to a value other than 48 kHz,
54
DPS-475/575 Service Manual
Chapter 6:
Menus: Audio Setup
SDI and DV inputs will be converted to the specified sample rate (except in DigiDuplex mode), but SDI audio embedding will not function. The sample rate is forced to 48 kHz when 96kHz AES Output mode (detailed earlier in this section) is enabled.
The Sample Rate setting affects the valid range of the Test Freq-L, Test Freq-R, and Fixed Delay options (detailed earlier in this chapter).

Valid Settings: Normal, Strict
Default Setting: Normal
Pitch Change
Controls the rate of frequency (pitch) change introduced by the system while delaying the audio.
Valid Settings: Fast, Normal, Slow
Default Setting: Normal
Related Settings: Auto Track, Fixed Delay
The Slow setting corresponds to 0.54% (1/64 tone) pitch change for Auto Track delay, and 6.67% for Fixed Delay.
The Normal setting corresponds to 1% pitch change for Auto Track delay, and 10% for Fixed Delay.
The Fast setting corresponds to 1.5% pitch change for Auto Track delay, and 20% for Fixed Delay.
Mute In Freeze
Specifies whether or not audio output should be muted when the incoming video is frozen in Frame or Field mode (see Chapter 5, “Menus: Video Setup”).
Valid Settings: On, Off

Dolby-E (Data) Mode
Enables or disables Dolby-E (Data) mode, which allows Dolby-E compressed data streams to be routed through the DPS-475/575.
Valid Settings: Off, On
Default Setting: Off
A number of restrictions apply when this option is enabled:
• DigiDuplex mode cannot be enabled when the Dolby-E (Data) mode is enabled. If DigiDuplex mode is already enabled, it will be automatically disabled when Dolby-E (Data) Mode is turned on.
• The Dolby-E (Data) mode operates only on channel 1. When Dolby-E (Data) Mode is enabled, the audio input selection for channel 1 automatically switches to AES/EBU.
• When Dolby-E (Data) Mode is enabled, gain for channel 1 is forced to unity. That is, the Ch1-Gain -R and Ch1-Gain-L options (detailed earlier in this chapter) are automatically set to 0.0dB, and cannot be changed until Dolby-E (Data) mode is disabled.
• SDI embedded audio is not supported.
Voice-Over Pgm. Level

Voice-Over
Activates and de-activates audio voice-over mixing.
Valid Settings: Off, Active
Default Setting: Off
Related Settings: Voice-Over Pgm. Level, Voice-Over Fade,
GPI-1 Function, GPI-2 Function, GPO Function
Voice-over mixing in the DPS-475/575 allows the program audio on input channel 1 to be ramped down, mixed with voice-over audio on input channel 2, and ramped back up upon completion of the voice-over.
When Voice-Over is activated, the program audio on input channel 1 will immediately begin ramping down to the setting of the Voice-Over Pgm. Level option. The duration of the ramp-down is specified in the Voice-Over Fade option. The voice-over audio on channel 2 is muted during this ramp-down. Once the ramp-down is complete, the program audio on input channel 1 will be mixed with the voice-over audio on input channel 2. When the Voice-Over option is later set back to Off (upon completion of the voice-over), the voice-over audio on channel 2 is again muted, and the program audio on input channel 1 will begin ramping back up to its original level.
Note that the gain of the voice-over audio on channel 2 will not be automatically adjusted. It is recommended that the user adjust the gain of channel 2 using the Gain- L and Gain-R options detailed earlier in this chapter, to compensate for the averaging/mixing that is occuring between channels 1 and 2 during the voice-over. The recommended gain for the voice-over audio on channel 2 is -0.5 * the value specified in Voice-Over Pgm. Level. For example, if Voice-Over Pgm. Level is set to - 6db, it is recommended that the user set Gain-L and Gain-R for channel 2 to 3db.
Voice-over mixing may be also be triggered through GPI control. When the GPI-1 Function or GPI-2 Function options (see Chapter 12, “Menus: System Config”) are set to Voice-Over, the unit’s audio voice-over mode will be activated by a GPI signal, exactly as if manually enabled. Voice-over mixing remains active while the GPI signal is present. Voice-over mixing is stopped and program audio begins ramping back up upon release of the GPI trigger, similar to setting Voice-Over back to Off.
When the GPO Function option of the System Config menu is set to Voice-Over, a GPI signal will be continuously output while the audio voice-over mixing is active. This signal will NOT be output during the fade-down and ramp-up of program audio that preceed and follow, respectively, voice-over mixing.

Enables and controls the strength of the luminance temporal noise reduction.
Valid Range: Comb-3D, Min, 2 to 15, Max
Default Setting: Comb-3D
Related Setting: 3D Comb Decoder, Temporal NR-Chroma
When this option is set to Comb-3D, luminance temporal noise reduction is disabled, allowing the use of the 3D comb filter decoder on luminance.
The other valid settings control the averaging effect of previous frames on the output; i.e. how heavily the output is weighted towards past frames vs. the current frame being processed.
When this option is set to Min, the output is based almost entirely on the current frame being processed. When this option is set to Max, the output is based almost entirely on information from past frames, creating an undesirable shadowing effect.
It is not possible to use both Temporal Noise Reduction and 3D combing on the same channel simultaneously. (For example, if Temporal NR-Luma is enabled, 3D combing of luminance is not possible, so the 3D comb decoder must be disabled or set to Chroma.) This is not a problem; with a sufficient Temporal Noise Reduction setting, there would be no benefit to using the 3D comb filter simultaneously.
Setting this option to any value other than Comb-3D automatically disables 3D combing of luminance in the 3D Comb Decoder option.
This setting will be automatically disabled (set to Comb-3D) if the user enables 3D combing on luminance (by setting 3D Comb Decoder to Luma or Both Y+C).
This option is ignored if the Noise Reduction option is set to Disabled.

RABBING
The TSG/Image Grabbing Setup Menu is used to capture frames from video for use as test patterns or keyed still images.
Grab 10-bit Video
Captures a 10-bit frame from video for use as a test pattern in the Test Signal Generator.
When this option is selected, a frame is grabbed from the currently selected input video signal. While the frame is grabbed, the video output will be briefly frozen, then resume live operation.
The captured frame is saved as a file named Grabbed. This file must be renamed in
the Flash Memory Mgmt option of the System Config menu, or else it will be overwritten by the next video grab.
Related Settings: Flash Memory Mgmt (System Config menu)
Grab 8-bit Video
Captures an 8-bit frame from video for use with the unit’s linear keyer.
When this option is selected, a frame is grabbed from the currently selected input video signal. While the frame is grabbed, the video output will be briefly frozen, then resume live operation.
When used by itself, this option creates a still image file that will be output full­screen by the keyer. The Grab Linear Key option (detailed later in this section) can be used in conjunction to add a key channel, thus creating a file that will be keyed over the incoming video. The Grab 8-bit Video option captures the fill (the “content” of the keyed image); the Grab Linear Key option is then used immediately afterward to grab an incoming key channel. (The key channel can be captured from a separate input, or the connections of the currently selected video input must be changed to provide the key signal.)
The captured frame is saved as a file named Grabbed. This file must be renamed in
the Flash Memory Mgmt option of the System Config menu, or else it will be overwritten by the next video grab. The file should not be renamed until the Grab Linear Key option has been applied, if a key channel is desired.
Related Settings: Flash Memory Mgmt (System Config menu),
Grab Linear Key
Grab Linear Key
Captures a linear key to be applied to the 8-bit video image just captured.
This option is used only in conjunction with the Grab 8-bit Video option detailed earlier in this section.
71
When this option is selected, a frame is grabbed from the currently selected input video signal, which must contain the key channel to be applied to the captured image. (The key channel can be captured from a separate input from that of the image, or the connections of the currently selected video input must be changed to provide the key signal.)
The key channel is incorporated into the image file named Grabbed. This file must
then be renamed in the Flash Memory Mgmt option of the System Config menu, or else it will be overwritten by the next video grab.

Grab & Apply Luma Key
Captures an 8-bit frame from video for use with the unit’s linear keyer, with its key channel defined by the current settings of the Luma Key Gain and Threshold options (detailed later in this section).
When this option is selected, a frame is grabbed from the currently selected input video signal. While the frame is grabbed, the video output will be briefly frozen, then resume live operation. The settings of the Luma Key Gain and Threshold options are used to define the key channel for the image from a luminance key, thus creating a file that will be keyed over the incoming video by the linear keyer. The settings of the
Luma Key Gain and Threshold options must be specified prior to the use of the Grab & Apply Luma Key function.
The captured frame is saved as a file named Grabbed. This file must be renamed in the Flash Memory Mgmt option of the System Config menu, or else it will be overwritten by the next video grab.

Chapter 12:
Menus: System Config
CHAPTER 12: MENUS: SYSTEM CONFIG
The System Config menu is used for configuration of the DPS-475/575. Settings in the System Config menu are generally used for initial setup of the unit, not in regular operation.
Line Standard (525/625) [DPS-575 Only]
Selects between 525-line (NTSC) and 625-line (PAL) standards.
Current
Displays the line standard currently in use:
525 lines Using 525-line standard, user-specified. 625 lines Using 625-line standard, user-specified. Auto (525) Using 525-line standard, auto-detected. Auto (625) Using 625-line standard, auto-detected
Switch to 525
This option is only available when the DPS-575 is currently running in 625-line mode (either user-specified or automatically detected). Selecting this option disables line standard auto-switching, and switches the unit to 525-line mode.
Switch to 625
This option is only available when the DPS-575 is currently running in 525-line mode (either user-specified or automatically detected). Selecting this option disables line standard auto-switching, and switches the unit to 625-line mode.
Disable Autoswitch / Switch to Auto
Enables or disables line standard auto-switching. When line standard auto-switching is enabled, the unit will automatically switch line standards based on the current input signal, and the Current field (described earlier in this section) will report Auto (XXX), where XXX is the detected line standard.
When line standard auto-switching is disabled, the unit will remain in the currently selected line standard, regardless of the video input.
Misc. Setup
Internal T emp
Reports the internal temperature of the unit, in Celsius.
73
Video Delay
Reports the current measured video delay, in ms.
Keylock
Enables the Keylock feature of the unit, which disables front-panel controls.
Valid Settings: Normal, Enable
Default Setting: Normal
This feature should be used only when the DPS-475/575 is being controlled remotely (for example, from a DPS RC-4000 remote controller). If this option is not activated (i.e. in Normal mode), then it is possible for a local user to modify the remote-user’s settings from the front panel. When enabled, this option disables front-panel access, so all control must be done remotely.
To return to Normal mode, press and hold the Enter and Exit front-panel buttons simultaneously, or change the Keylock setting from the remote controller.
Function Bypass
Toggles between the master Process and Bypass modes. Process mode is the normal mode of operation. In Bypass mode, no processing is applied to the Composite In video signal; it is passed directly to Composite Out. Similarly, in Bypass mode, no processing is applied to the analog and AES/EBU audio inputs; they are routed directly to the outputs.
Valid Settings: Process, Bypass
Default Setting: Process
This is equivalent to the user of the Bypass button on the front panel. The light on the Bypass button flashes while the unit is in master Bypass mode.
Composite In and the analog and AES/EBU audio inputs are also bypassed when the
power to the unit is off.
This option can override the Analog Bypass and AES/EBU bypass options in the Audio Setup menu. If Function Bypass is enabled (set to Bypass), the analog and AES/EBU audio inputs are bypassed, regardless of their setting in the Audio Setup menu.
GPI-1 Function
Selects which function should be triggered when a GPI pulse is received on the GPI-1 connection of the Multi I/O breakout cable.
Valid Settings: Disabled, Freeze, Keyer, Trouble Slide, User 1,
Voice-Over
Default Setting: Disabled
When Disabled, no action will be taken on receipt of a GPI pulse.
When set to Freeze, the currently selected Freeze Mode (see Chapter 5, “Menus: Video Setup”) will be applied to the incoming video while a GPI signal is present, similar to pressing the Take button on the front panel of the unit. The live video feed will be resumed when the GPI trigger is released.
74
DPS-475/575 Service Manual
Chapter 12:
Menus: System Config
When set to Keyer, the unit’s linear keyer will turn on and remain active while a GPI signal is present. The keyer will turn off upon release of the GPI trigger.
When set to Trouble Slide, the currently selected trouble slide is displayed on the outputs while a GPI signal is present. The Trouble File option of the Video Setup menu is used to select the trouble slide to be displayed. The trouble slide is removed from the display upon release of the GPI trigger.
When set to User 1, an incoming GPI pulse is equivalent to pressing the user­programmable User 1 key on the front panel of the unit. In this manner, the unit can be configured to select almost any function on an incoming GPI pulse. See the section on User-Programmable Keys in Chapter 3, “Operation - Front Panel Controls,” for details on assigning a function to the User 1 key.
For example, if the User 1 key is assigned to the AGC Bias function, and the GPI-1 Function option is set to User 1, the first incoming GPI pulse will take the user to the AGC Bias adjustment screen; each subsequent GPI pulse will cycle through the allowed adjustment values.
When set to Voice-Over, the unit’s audio voice-over mode (see Chapter 6, “Menus: Audio Setup”) will be activated by a GPI signal. When the GPI signal is first received, program audio begins fading down, then voice-over mixing begins. Voice­over mixing continues while the GPI signal is present. Voice-over mixing is stopped and program audio begins ramping back up upon release of the GPI trigger. This GPI option is similar to activating and de-activating the Voice-Over option of the Global Audio Config sub-menu.
GPI input can be contact closure to ground or TTL signal (0 to 5 volts max.).
GPI-2 Function
Selects which function should be triggered when a GPI pulse is received on the GPI-2 connection of the Multi I/O breakout cable.
Valid Settings: Disabled, Freeze, Keyer Off, Trouble Slide, User 2,

Default Setting: Disabled
When Disabled, no action will be taken on receipt of a GPI pulse.
When set to Freeze, the currently selected Freeze Mode (see Chapter 5, “Menus: Video Setup”) will be applied to the incoming video while a GPI signal is present, similar to pressing the Take button on the front panel of the unit. The live video feed will be resumed when the GPI trigger is released.
When set to Keyer Off, the unit’s linear keyer will be turned off upon receipt of a GPI pulse.
When set to Trouble Slide, the currently selected trouble slide is displayed on the outputs while a GPI signal is present. The Trouble File option of the Video Setup menu is used to select the trouble slide to be displayed. The trouble slide is removed from the display upon release of the GPI trigger.
When set to User 2, an incoming GPI pulse is equivalent to pressing the user­programmable User 2 key on the front panel of the unit. In this manner, the unit can be configured to select almost any function on an incoming GPI pulse. See the section on User-Programmable Keys in Chapter 3, “Operation - Front Panel Controls,” for details on assigning a function to the User 2 key.
For example, if the User 2 key is assigned to the AGC Bias function, and the GPI-2 Function option is set to User 2, the first incoming GPI pulse will take the user to the
75
AGC Bias adjustment screen; each subsequent GPI pulse will cycle through the allowed adjustment values.
When set to Voice-Over, the unit’s audio voice-over mode (see Chapter 6, “Menus: Audio Setup”) will be activated by a GPI signal. When the GPI signal is first received, program audio begins fading down, then voice-over mixing begins. Voice­over mixing continues while the GPI signal is present. Voice-over mixing is stopped and program audio begins ramping back up upon release of the GPI trigger. This GPI option is similar to activating and de-activating the Voice-Over option of the Global Audio Config sub-menu.
GPI input can be contact closure to ground or TTL signal (0 to 5 volts max.).
GPO Function
Selects the functionality of the GPI Output/Audio Delay Pulse connection of the Multi I/O breakout cable.
Valid Settings: Audio Pulse, Bad Input, Keyer Active,
SDI Input, Voice-Over
Default Setting: Audio Pulse
When set to Audio Pulse, a pulse will be sent on this output at a regular interval (approximately every two frames).
When set to Bad Input, a signal will be continuously output when no valid video signal is present on the currently selected video input.
When set to Keyer Active, a signal will be continuously output when the unit’s linear keyer is active.
When set to SDI Input, a signal will be continuously output when the unit’s input video selection is set to SDI.
When set to Voice-Over, a signal will be continuously output while the audio voice- over mixing is active. This signal will NOT be output during the fade-down and ramp-up of program audio that preceed and follow, respectively, voice-over mixing.
“Active” output is TTL compatible, 5 volts / 20 mA max.
Genlock Changes
Enables or disables the ability of the operator to make changes to the genlock timing settings found in the Timing Setup menu.
Valid Settings: Enabled, Disabled
Default Setting: Enabled
When this setting is disabled, changes cannot be made to the unit’s genlock timing options.

One-T ime Video Setup
Source ID
Specifies the Source ID text. The text can be up to 23 characters long, and is set by using the Enter key and control knob.
Pressing the Enter key cycles through which character position (1 to 23) is to be modified; the control knob selects a new character for that position. Two consecutive spaces are not allowed; attempting to move to the next character position after a space will return to the first character position.
Pressing the Exit key stores the new Source ID.
Setup level (in)
Specifies whether or not the input video signal includes setup. This setting is not applicable in 625-line mode [PAL].
Valid Settings: With, Without
Default Setting: With
Setup level (out)
Specifies whether or not setup should be included in the video output. This setting is not applicable in 625-line mode [PAL].
Valid Settings: Add, No Setup
Default Setting: Add
77
Chroma Coring
Specifies whether or not to disable chroma coring of the video signal.
Valid Settings: Normal, Disable
Default Setting: Normal
Chroma coring should only be disabled when multiple generational passes of the same video signal are being processed through the unit. Disabling chroma coring reduces “chroma contamination” that can occur after four or five recursive passes (Analog -Digital - Analog - Digital, etc.).
Note that disabling chroma coring may have a slight effect on chroma gain, as units are factory-calibrated with the Chroma Coring option in the Normal setting.
VITS/Blanking Fld1
Specifies blanking and Vertical Interval Test Signal insertion options for field 1 of the video.
In 525-line mode (NTSC), the first 9 lines of field 1 are always blanked. The Narrow Blanking option sets lines 10 through 20 of field 1 to Bypass, so they are unchanged from the input. Wide Blanking sets lines 10 through 20 of field 1 to Blank, so they are blanked. Enable Source ID inserts the text specified in the Source ID option into lines 10 through 20.
In 625-line mode (PAL), the first 5 lines of field 1 are always blanked. The Narrow Blanking option sets lines 6 through 22 of field 1 to Bypass, so they are unchanged from the input. Wide Blanking sets lines 6 through 22 of field 1 to Blank, so they are blanked. Enable Source ID inserts the text specified in the Source ID option into lines 6 through 22.
These options can be overriden on a line-by line basis with the remaining settings of this option. Each of lines 10 through 22 can be individually configured. Each of lines 10 through 20 can be set to:
• Blank: the line will be blanked
• Bypass: the line will be sampled from the input video, then passed through a notch filter before output. This mode assumes that color information may be present in the line.
• Data: the line will be sampled from the input video, and output without any processing. This mode should be used for high-speed signals that may be corrupted by filtering.
• Source ID: the text specified in the Source ID option is inserted
• a Vertical Interval Test Signal
In 625-line mode, lines 21and 22 can each be set to any of the above values. In 525­line mode, lines 21 and 22 can each be set to either Bypass or Blank.
Related Setting: Source ID, VITS/Blanking Fld2
VITS/Blanking Fld2
Specifies blanking and Vertical Interval Test Signal insertion options for field 2 of the video.
78
DPS-475/575 Service Manual
Chapter 12:
Menus: System Config
In 525-line mode (NTSC), the first 8 lines of field 2 are always blanked. The Narrow Blanking option sets lines 9 through 19 of field 2 to Bypass, so they are unchanged
from the input. Wide Blanking sets lines 10 through 19 of field 2 to Blank, so they are blanked. Enable Source ID inserts the text specified in the Source ID option into lines 10 through 19. Line 9 of field 2 is always set to Bypass.
In 625-line mode (PAL), lines 314 through 318 are always blanked. The Narrow Blanking option sets lines 319 through 335 to Bypass, so they are unchanged from the input. Wide Blanking sets lines 320 through 335 to Blank, so they are blanked. Enable Source ID inserts the text specified in the Source ID option into lines 320 through 335. Line 319 is always set to Bypass.
These options can be overriden on a line-by line basis with the remaining settings of this option. Each of lines 10 through 21 (525-line mode) or 320 through 335 (625-line mode) can be individually configured. Each of lines 10 through 19 (320 through 335 in 625-line mode) can be set to:
• Blank: the line will be blanked
• Bypass: the line will be sampled from the input video, then passed through a notch filter before output. This mode assumes that color information may be present in the line.
• Data: the line will be sampled from the input video, and output without any processing. This mode should be used for high-speed signals that may be corrupted by filtering.
• Source ID: the text specified in the Source ID option is inserted
• a Vertical Interval Test Signal
In 525-line mode, lines 20 and 21 can each be set to either Bypass or Blank.

Unit Address (serial)
Specifies the address of the unit for remote serial control. The unit will only respond to commands sent to this serial address, allowing it to be used in a multi-drop configuration. Each unit must have a unique address setting.
Valid Range: 1 to 127
Default Setting: 1
IP Address
Specifies the IP address of the unit on a TCP/IP network. The IP address is used when the unit is to be controlled via the 10BaseT Ethernet port.
The IP address must be set to be consistent with your existing TCP/IP network and the remote machine that will be controlling the unit. Your network administrator can provide you with an appropriate IP address to use.
IP addresses are represented as four numbers (each from 0 to 255), separated by periods (for example, 10.0.0.1).
The IP Address option is set by using the Enter key and control knob. Pressing the Enter key cycles through which of the four numeric components of the IP address is being modified; the control knob sets the value of that numeric component, from 0 to
255. Pressing the Exit key stores the IP address.
Default Setting: 10.0.XX.YY where XXYY is the unit serial number
Related Settings: Netmask, Gateway
Netmask
Specifies the subnet mask of the unit on a TCP/IP network. The subnet mask is used when the unit is to be controlled via the 10BaseT Ethernet port, and is represented as four numbers separated by periods (for example, 255.240.0.0).
The subnet mask must be set to be consistent with your existing TCP/IP network and the remote machine that will be controlling the unit. Your network administrator can provide you with an appropriate subnet mask to use.
Valid Range: 128.0.0.0 to 255.255.255.240
Default Setting: 255.255.0.0
Related Settings: IP Address, Gateway
Subnet mask settings are often represented as hexidecimal digits, for example 0xFFFF0000. Translation of this notation is straightforward, as each pair of hexidecimal digits is converted to its decimal equivalent (FF = 255, F0 = 240, etc.). Thus, the above example is equal to 255.255.0.0; 0xFFFFF000 is equal to
255.255.240.0.
Gateway
Specifies the IP address of the network gateway for the unit on a TCP/IP network. The Gateway setting is used when the unit is to be controlled via the 10BaseT Ethernet port.
