5230 and 6230 OVERVIEW
The 5230 takes serial digital component and converts the signal into either composite or
component analog video outputs. 8x oversampling and 12 bit processing ensure high
quality conversion for use in the most demanding applications.
The 5230 has a full-featured Proc Amp for adjustment of every signal parameter. Proc
controls include video and chroma gain, NTSC style hue rotation, black balance, and
pedestal.
Selective (toothed) vertical blanking lets you choose to pass or strip content in the vertical
interval on a line by line and field by field basis.
The output timing of the 5230 is fully adjustable relative to the reference input signal.
Composite outputs can be precisely color-timed and will also track color framing of the
reference signal. Incorporating a full frame synchronizer, the 5230 accepts serial inputs
that are asynchronous to the reference.
The 6230 is an optional audio submodule for disembedding or converting. This audio
processor option has AES audio inputs and analog outputs, and the ability to disembed
audio from the serial digital video stream. Disembedded audio or signals from any of the
inputs may be mixed, shuffled or level controlled and any of the channels re-embedded
and/or sent to the analog output connectors.
Full audio delay tracking is included as well as the provision to add fixed delay to correct
incoming lip sync errors. There is built-in sample rate conversion allowing use of asynchronous AES inputs, while synchronous AC-3 or Dolby-E audio signals may also be used.
As always, the comprehensive Avenue control system allows for monitoring and adjustment of all parameters through networked Touch Screen or PC control.
Other features include the following:
• Clips and chroma limiting
• Composite legalizer
• Internal color bars test generator
Power is derived from the ± 12 volt frame power. It is regulated to the required + 5 volts
for the digital circuitry and ± 8 volts for the analog circuitry by on-board regulators. The
module is fused with a resettable fuse device. If the fuse opens due to an overcurrent
condition, the module will lose power. After pulling the module, the fuse will reset automatically requiring no replacement fuse.
The on-board CPU can monitor and report module ID information including slot location,
software version and board revision and other data to the optional frame System Control
module. This information can be accessed by the user or set to register an alarm if desired
using the remote control options available.
Every function and parameter on the 5230 module can be controlled from an Avenue
Touch Screen Control Panel, or the Avenue PC Control Application. Memory registers can
be used to save the complete configuration of the module, making it easy to change
instantly between different configurations.

APPLICATIONS
This section provides some typical applications for utilizing the full versatility of the 5230
Video Processor module and the optional submodule, the 6230 Audio Processor.
Video Server Feeding an Analog Switcher
As illustrated in the block diagram below, the 5230 accepts a serial digital video input
with embedded audio from a video server. The digital video will be converted to composite
analog and fed to an analog switcher. The embedded audio in the serial digital stream will
be disembeded and converted to analog audio outputs in the 6230 submodule.
Proper audio/video timing can be assured when the tracking audio delay of the 6230 Audio
Processor is employed. Any timing or delay modifications to the video are tracked by the
6230 whether you wish to use disembedded audio or audio input from an AES source.
Properly timed audio from any of these sources is available directly when routed to the
analog audio outputs. A fixed delay of up to 1000 mS can be inserted by the 6230 to
correct for signals which have previously passed through frame stores without audio delay
compensation.

INSTALLATION
6230 Submodule Installation
The optional 6230 Audio Processing submodule installs on the component side of the 5230
Video Processing module circuit board. If the option is ordered with the 5230 module, it
will come already installed.
To install the 6230 Audio submodule, locate the three connectors on the left side of the
circuit board as shown below and line the connectors up, checking the alignment. Press
carefully into place to seat the submodule.
5230 Video Processing Module
Plug the 5230 module into any one of the slots in the 1 RU or 3 RU frame and install the
plastic overlay provided onto the corresponding group of rear BNC connectors associated
with the module location. Note that the plastic overlay has an optional adhesive backing
for securing it to the frame. Use of the adhesive backing is only necessary if you would
like the location to be permanent and is not recommended if you need to change module
locations. This module may be hot-swapped (inserted or removed) without powering down
or disturbing performance of the other modules in the system.
CABLING
Refer to the 3 RU and 1 RU backplane diagrams of the module on the following page for
cabling instructions. Note that unless stated otherwise, the 1 RU cabling explanations are
identical to those given in the 3 RU diagram.

MODULE CONFIGURATION AND CONTROL
The configuration parameters for each Avenue module must be selected after installation.
This can be done remotely using one of the Avenue remote control options or locally using
the module front panel controls. Each module has a REMOTE/LOCAL switch on the
front edge of the circuit board which must first be set to the desired control mode.
The configuration parameter choices for the module will differ between Remote and
Local modes. In Remote mode, the choices are made through software and allow more
selections. The 5230/6230 Parameter Table later in this section summarizes and
compares the various configuration parameters that can be set remotely or locally and the
default/factory settings. It also provides the default User Levels for each control. These
levels can be changed using the Avenue PC application.
If you are not using a remote control option, the module parameters must be configured
from the front panel switches. Parameters that have no front panel control will be set to a
default value. The Local switches are illustrated in the Front Panel Controls and
Indicators section following the 5230/6230 Parameter Table.
Avenue module parameters can be configured and controlled remotely from one or both of
the remote control options, the Avenue Touch Screen or the Avenue PC Application. Once
the module parameters have been set remotely, the information is stored on the module
CPU. This allows the module to be moved to a different cell in the frame at your discretion without losing the stored information. Remote configuration will override whatever
the switch settings are on the front edge of the module.
For setting the parameters remotely using the Avenue PC option, refer to the Avenue PC
Remote Configuration section of this document.
For setting the parameters remotely using the Avenue Touch Screen option, refer to the
Avenue Touch Screen Remote Configuration section of this document following
Avenue PC.
Configuration Summary
This section provides a general overview of the configuration for the 5230 module. The
controls available for configuration with remote control are summarized and tips and
examples are given for using particular controls to achieve the best results.
Video Processing
The 5230 has a full-featured Proc Amp for adjustment of every signal parameter. Proc
controls include video and chroma gain, NTSC style hue rotation, black balance, and
pedestal. Black and white clips can be set to prevent excessive signal excursions.
Certain values represented in serial digital component may be illegal in the NTSC or PAL
composite domains. The Predictive Composite Clipper mode identifies picture elements
that would be illegal in analog composite, and limits color saturation and luminance
excursions. You can be confident that the work you’re doing in digital component will look
its best in composite.
Selective (toothed) vertical blanking lets you choose to pass or strip content in the vertical
interval on a line by line and field by field basis.
5230/6230-8
Model 5230/6230 Video Audio DAC
The 5230 has analog composite or analog component outputs. They are fully timed to your
house reference, including the subcarrier and ScH phase of the composite output. The
analog output is constructed at 8x oversampling with 12 bits of quantizing resolution.
The available video processing remote control menus are summarized below:
• Proc Menu: Gain, Chroma, Pedestal and Hue are standard Proc Amp controls.
Even though the input is SDI, the Hue control gives phase rotation of the color
vectors in the manner of an NTSC composite Proc Amp.
• Clip: The Legalizer is a predictive clipper which insures signal levels will not
exceed those permitted in the composite domain. Thus its use can insure a television transmitter will not be presented illegal video input. If Off or Legal are
selected other adjustments are grayed and may not be changed. While Legal automatically puts in values to insure signals will not exceed composite legal limits,
selecting Custom allows the operator to insert a range of clip values.
• Timing: The 5230’s comprehensive range of timing allows complete flexibility in
placement of the output picture relative to the applied reference input. Fine Phase
and Hor Timing take the horizontal timing across the entire line with nanosecond
accuracy. A Vert Timing adjustment completes the range in allowing any output
timing desired by the operator.
• Status: This dynamic monitoring display provides indicators of video and audio
inputs and EDH error status. The 6230 will show in the Option window when
present.
• Trim: Cb and Cr offsets allow black balance to be corrected while Cb and Cr gains
permit trimming of levels on these two axes. Y/C delay allows the operator to
correct inaccuracy of timing of color information relative to luminance. These trims
are functional regardless of the input or output formats in use.
• Blanking: There are Wide, Narrow or Custom blanking choices. Wide gives
blanking through line 20 (NTSC) or line 22 (PAL), while narrow produces blanking
through line 9 (NTSC) or Line 6 (PAL) of both fields. In the Custom mode any individual lines from 9 through 23 may be selectively blanked, with different choices
allowed for each field. Some systems recognize position of the V-bit to control end
of blanking. In the 525 standard V-bit position can be set to line 10, line 20 or line
23. In 625 mode V-bit is fixed at line 23 as this is the only position permitted by
the 625 Standard.
• Memory: Up to five configurations of the 5230 may be saved into memory
registers for later recall. All parameters – gains, input format, filters, blanking,
etc. - are saved in each memory. The 5230 can be used with component analog
outputs in a particular application. In another application it is used with
composite input, noise reduction and embedding of audio from an analog audio
input source. These two setups could be stored in memory registers and one or the
other recalled for instant restoration of the required configuration.
5230/6230-9
Model 5230/6230 Video Audio DAC
6230 Audio Processor Configuration
The 6230 Audio Processor will accept audio from the AES input connectors and can
disembed audio from the incoming SDI video stream. Between the input and output is a
4x4 audio mixer with tracking audio delay. Any incoming audio can be mixed, level controlled and/or shuffled to another output channel by means of the integrated audio router.
The tracking audio delay allows synchronization and timing to be maintained with time
base corrected video passing through the video frame synchronizer of the 5230.
A built in sample rate converter allows use of asynchronous AES input signals. The 6230
also supports encoded audio formats such as AC-3 and Dolby-E. All audio processing is
performed at the full 24 bit resolution of the system. At the output side of the 6230
submodule the four audio channels are routed to analog output connectors. An adapter is
also available to allow the AES I/O to be converted from BNC to 110 ohm balanced.
The available audio processing remote control menus are summarized below:
• Audio In: Status indicators show presence of AES and embedded (SDI) audio
inputs. The In 1/2 Sel and In 3/4 Sel controls provide for selection of inputs to the
4x4 audio mixer. The choices for each are AES 1/2, SDI 1/2, AES 3/4, and SDI 3/4.
Thus any pair of input audio signals can be routed to either pair of input buses of
the 4 input 4 output audio mixer. This allows full flexibility of audio routing.
• Audio Mix: This menu gives full access to the 4x4 audio mixer controls. Any input
channel can be routed to any or all output busses. Sliders or Touch Screen rotary
knobs permit levels to be adjusted from -70dB to +12dB. Alternatively a value can
be put in the numeric window, followed by the Enter key, and this will become the
new gain setting. Default buttons are provided for return to zero level.
The Tie function is used for stereo operation where gain of a pair of channels is
usually desired to be the same. An invert selection allows inversion of a channel to
permit phase correction.
• Audio Delay: With the Auto Track switched On, audio will be delayed the same
amount as the video passing through the 5230 frame synchronizer thus preserving
lip sync. If incoming audio is early due to signals passing through an upstream
frame sync without a compensating audio delay, Bulk Delay can be used to correct
the problem. Up to 1000 mS of fixed delay can be added to compensate for
upstream timing errors.
