Introduction

PQM300 Program QoS Monitor Service Manual

Specifications

Product Description

This section lists the electrical, physical, and environmental characteristics of the PQM300 Program QoS Monitor.

NOTE. Version 2.0 of the PQM300 application software must be installed to support the Alarm Relay board and the Local Control Flat Panel Display options.

The program monitor is implemented on a platform that uses Microsoft’s Windows NT operating system. Operating an a networked system, the PQM300 program monitor application is configured to begin automatically after the power-on initialization and program loading are completed.

An optional SVGA monitor can be connected for a local display and the program monitor can be controlled using a keyboard and a mouse.

The PQM300 program monitor provides program service quality assessments of live Rec. 601 digital video signals. Quality of Service (QoS) monitoring provides the following assessments and capabilities:

MPEG Defects

H Real-time MPEG defect (Discrete Cosine Transform based blockiness

artifacts) monitoring and reporting when a signal is present. The PDI level (Picture Defect Indicator) provides immediate and continuous indication of the video image quality.

H Fixed (manual) setting of blockiness period for a given pixel block size for

the MPEG defects measurement.

H Adaptive settings to automatically determine blockiness periods used for the

MPEG defects measurement.

H Period selection to monitor the detected blockiness period. This is a tool to

find the correct period for the fixed period setting and to monitor the incoming video for blockiness period changes.

Frozen Frame, Repeated Frames, Loss of Service

H Video content constant (consecutive fields exactly identical)

PQM300 Program QoS Monitor Service Manual

Specifications

H Repeated frame found in a moving sequence H Absence of a serial digital video signal H Absence of video content on the input

Uncorrelated Noise

H Indicates the amount of white Gaussian noise in the video signal (such as

that injected by analog video circuits)

Alarm Level Monitoring

H Individual alarm settings for all measurements (including blockiness period) H Level thresholds for amplitude of error H Time thresholds in number of fields for duration of error condition H Percentage thresholds for an amount of error within a defined time threshold

Remote Control and Networking

H Web Browser control and monitoring of any program monitor accessible

over a TCP/IP network. Access is through the Netscape (4.5 or higher) or the

Internet Explorer (4.0 or higher) Web browser. An applet provides a remote

user interface to make all the configuration setups and display the measure-

ment results. H SNMP agent (Simple Network Management Protocol) and MIB (manage-

ment information base) for integration into an existing SNMP infrastructure

to monitor picture quality from a central control point H Multi-machine networking. A networked Windows NT PC or a PQM300

program monitor with local display, keyboard, and mouse, can be used to

control and monitor all PQM300 program monitors accessible over the

network.

NOTE. A locally attached SVGA monitor, mouse, and keyboard are used for the initial set up of the PQM300 Program QoS Monitor.

Continuous Measurements

1–2

Measurements run continuously to monitor program quality in real-time. An operator at a central control station can control the operation of the program monitor installed in a system network.

Program Channels

Program Monitor

Connections

One channel of program monitoring is provided for each installed program monitor module in a PQM300. Two Rec. 601 serial digital video monitor channels are included with the standard configuration. Up to six additional program monitor modules can be installed for a total of eight digital video channels. Composite video programming can be monitored using a composite decoder to provide 601 digital video to the program monitor modules. Use either your own high quality decoder or install the Tektronix PQM3F01 composite decoder modules in the PQM300 to handle the composite decoding task. You can choose to install one or more composite decoder modules to provide monitor channels for composite video. Up to four composite decoder/program monitor pairs can be installed in each machine when using the Tektronix composite decoder modules.

Before you start the PQM300 application, connect the 601 serial digital video program material (either 525 or 625 video standard) to be monitored to the Program Monitor CHANNEL A IN BNC connector as shown in Figure 2–3. The applied signal is either direct 601 serial video program material or it can be a 601 serial video signal obtained from a composite video decoder. When the measurements on a monitored channel start, the video standard connected to the program monitor module input is automatically recognized. The composite decoder does not recognize the applied video standard and must be preset to the correct standard. If you use the composite decoder, select the video standard of the composite video using the decoder initialization dialog box prior to starting the measurements (see Configuring the Composite Decoder on page 2–27).

NOTE. Do not change the video standard applied to a Program Monitor module input while the PQM300 measurements are running.

Optional Alarm

Relay Board

The Tektronix PQM3FRB alarm relay board option uses two 25-pin sub-D male connectors to the relay contacts. The PQM300 program monitor can be ordered with the alarm relay board installed or the board can be added later as an upgrade. If installed as an upgrade, Version 2.0 of the PQM300 application software must also be loaded to support this option.

The alarm relay connector pins described in Table 2–2 are two contacts (one normally open and the other normally closed) and the center (common) connector of each relay. The relay closes during each error recorded by the program monitor channel that is assigned to the relay. More than one channel can be assigned to the same alarm relay, and it also possible to assign the same channel to multiple relays. See Table 2–2 for the pin assignments for the relay board. Refer to Configuring the Alarm Relay Board on page 2–30 for information on how to make the channel assignments to the relay contacts.

NOTE. Use the provided alarm board cable, Tektronix part number 174-3562-00 on the alarm board connectors and twist them together to meet the demonstrated EMI performance given in the Specification section of this manual.

First Time Operation

Local Operation

This section contains the procedure for powering on the instrument for the first time. After the initial setup to install the program monitor in a network, it is ready to operate. The program monitor can also act as a stand-alone monitoring instrument when configured for local operation as described in the following paragraphs.

For the initial setup, access the controls of the PQM300 locally by connecting an optional SVGA monitor for local display and a keyboard and mouse for entering commands and operating the controls. The mouse cursor and buttons are used to select and activate the on-screen menu selections. Use the keyboard to enter parameter changes, file names, and edit any other user configurations choices that permit keyboard entries. The SVGA monitor connection is on the rear panel as one of the connections from the mainframe controller (see Figure 2–1 on page 2–3). The hot-pluggable mouse and keyboard may be connected either to the left front side connectors on the side of the bezel or to the mouse and keyboard connectors on the rear panel.

If your program monitor was ordered with the local control option, you can use the LCD flat panel display and touch screen on the instrument for the display. Use the keyboard and mouse that are provided with the option to aid in making the data entries and selections needed for the initial setup for operation. Refer to Local Control Option Front Panel Controls on page 2–33 for operating instruction for the keypad and touch screen.

Operating Information

To power off the instrument, refer to Powering off the Program Monitor on page 2–19.

First Time Power On

Power on the program monitor for the first time as follows:

NOTE. If the PQM300 program monitor has the local control front panel display installed, you do not need to connect an external SVGA monitor.

1. Connect an SVGA monitor for a display and a keyboard and mouse for user

command inputs. See Figure 2–1 and Figure 2–2 for the connector locations. You can connect the keyboard and mouse either to the rear panel connectors or to the left side connectors.

2. Press the On/Stby switch to power on the instrument (see Figure 2–6 for the

switch location). Whenever you power on the program monitor, it goes through the initializa-

tion and starts the PQM300 application without the need to enter a user name and password as normally required for a Windows NT operating system.

6. If autologin is disabled as described in the preceding note, use the key

sequence CTRL + ALT + Delete to display the log-in dialog box. Login as

TEKMONITOR and use TEKMONITOR as the password.

7. Check and set the program monitor clock to the correct system time.

NOTE. Check and set program monitor clocks against GMT (UTC) for the best accuracy. Do not set the program monitor clock back while the application is running. The time stamps for the history files and defects logs are obtained from the picture monitor clock. If conflicting times are found on the files, an error can occur. If you must reset the time, either set the time ahead, if needed, or wait until the new time setting is later than previous time setting to begin the PQM300 application again.

The PQM300 program monitor can be used as a stand-alone instrument, but it will seldom be used that way except initially to get the networking configured. To install the program monitor in a network, it must be configured for the network and provided with a network IP address. Specific items that need to be configured in the networking properties can vary depending on the local network requirements.

Networking the PQM300

Web Browser Remote

Control

24. Save and close the file.

The PQM300 program monitor must be installed in a network system if it is to be controlled and accessed using remote control features. The IP address, or the computer name assigned to the IP address, identifies the machine location for proper operation within the managed network. Refer to Configure the Network Properties on the preceding page.

NOTE. Limit the total number of connections (Web browser, SNMP Network, and ethernet) to a PQM300 program monitor to no more than three for best performance. More connections can be made, but the response of the program monitor server slows down. There is a imposed limit of three Web browser connections to a program monitor.

A good choice of a PC for the control and monitor task is one with Pentium processor of 200 MHz or better, 64 Mbytes or more of RAM memory, and with either a direct network connection or a fast modem. Computers with less capability may be used with good results, but expect slower update rates. You can control and monitor the quality of service measurements of any networked PQM300 program monitor through the virtual front panel (UI) using a Web Browser.

PQM300 Program QoS Monitor Service Manual

2–13

Operating Information

Web Browser Requirements. You can use Netscape version 4.5 or higher, or Internet Explorer, version 4.01 with SP2 (Service Pack 2) or higher. To be able to use the Internet Explorer browser, the JVM (Java Virtual Machine) version 5.0 must also be installed. The security setting on the Internet Explorer must also be set low enough to permit the Java applet to run.

Web Browser Access. Access any networked program monitor that is on the internet by starting the Web browser on your PC and entering either the network computer name or IP address for the PQM300 you want to access in the URL Location block. For example, if the host name for the machine on the network is PQM1 and its network address is PQM1.tek.com, enter http://PQM1.tek.com. If its IP address is known, enter that number (for example, http://128.181.39.60). The program monitor must be properly configured in your network. The virtual user interface displayed by the applet provides an interactive window for operating the accessed PQM300 program monitors.

SNMP Remote Control

A second networking approach is to control the program monitor in a networked system using SNMP (Simple Network Management Protocol). Refer to Appendix D, SNMP Networking in the PQM300 Program QoS Monitor User Manual for information on configuring and installing the program monitor in an SNMP network. You can use third party software for SNMP network control for the management application. If you have an SNMP network manager installed to control your networked devices, the PQM300 MIB and SNMP agent supplied with the application software can be added to the system. Refer to Installing and Using SNMP Services on page A–11 in Appendix A for important file configuration requirements. Refer to your third party SNMP software instructions for the information needed to install the PQM300 program monitor MIB in your networked system.

SNMP Agent. An SNMP agent is a processing entity that conveys the management information between the agent and the management station. The necessary agent software is provided as part of the PQM300 application software, but it does not start automatically. An SNMP shortcut icon is provided on the desktop. Double click the icon to launch the SNMP agent that enables SNMP network connections.

MIB. The PQM300 management information base (MIB) provides the information needed to control the operation, conFigure the measurements, and monitor the activity of the program monitor from a management station. The management information base for the program monitor is shown in Appendix D, SNMP Networking of the PQM300 Program QoS Monitor User Manual.

Operating Information

program monitor with a local display, keyboard, and mouse connected using the Windows NT networking facilities. Each PQM300 program monitor that is connected through a network to another PQM300 program monitor can be controlled, configured, and monitored by the control PC. Your system administrator must provide the IP addressing and configuration settings needed to properly network PQM300 program monitors in your local network.

DNS T able. To locate the PQM300 program monitors on a local network, a DNS (dynamic name server) Table must be created. If the DNS server is maintained by a centralized administration, that service has to make the appropriate entries to enter the program monitors on the network. For a local network without a centralized administration, the appropriate information must be available on the program monitors in the network. The name server looks at the Host file to find the IP addresses and assigned net names to identify a machine on the network. The Host file, shown in Figure 2–7, is in the C:\WINNT\system32\drivers\etc directory.

NOTE. The local machine is listed twice in the Host file; once as the localhost and again with its net name.

Use Notepad to open the file and edit the file to add the machine IP addresses and net names for the PQM300 program monitors on the local net.

PQM300 Remote

Application Program

The PQM300 remote application can be downloaded to a PC from any of the networked PQM300 program monitors using the Web Browser. Once you download the remote application, you can run it on a PC that does not have the PQM300 modules installed. You can use this method of accessing the PQM300 program monitors when the PC is dedicated to monitor and control of the networked program monitors, but it is especially beneficial when you use the PC primarily for other tasks or you monitor through a dial-up modem.

After connecting to the PQM300 program monitor, click on the line Download PQM300 Remote Application (Self Extracting 7Mb)" to download the application.

You can also load the PQM300 Remote Application execuTable directly from the application CD provided with the program monitor with the following procedure:

1. Place the CD in the CD drive of the PC you want the program loaded on.

2. Cancel the installation process that starts automatically.

3. Open the directory of the CD and locate the PQM300 Remote.exe file.

4. Select the file in the directory and drag it to the desktop of the PC.

5. Double click on the PQM300 Remote application icon to start the installa-

tion. The PQM300 Remote application is self extracting and automatically loads to the PC.

Incoming Inspection

After the program is installed, either from the Web download or copied from the CD, double click on the PQM300 icon that is now on your PC desktop to start the application. Operation through the application installed on your PC is the same as operation using the interface that is displayed by the applet, however, the user interface does not have to reload each time you connect to a networked PQM300 program monitor. Simply start the PQM300 application and connect to any PQM300 that is known on the network. Refer to Making Program Monitor Connections on page 2–26 for the procedure.

Incoming inspection consists of verifying basic operation of the PQM300 program monitor. The Power-on diagnostics check basic functionality. These diagnostics run every time you power on the instrument. If a failure is detected, the Power-on diagnostics dialog box opens with the failed test indicated. A functional check of the MPEG Defect measurement is provided in the Perfor- mance Verification section of this manual.

2–16

PQM300 Program QoS Monitor Service Manual

Diagnostics

The PQM300 program monitor has built-in self diagnostics to act as the first level of failure location and to act as part of the functional verification check. The program monitor performs power-on diagnostic testing. This testing consists of running the Windows NT power-on tests for checking the server and the boot-up testing of the program monitor modules. Additional diagnostic tests are performed on all installed Tektronix modules (such as the composite decoder or alarm relay board modules) to determine if they are operational.

Create an Emergency Repair Disk

A disk titled PQM300 Windows NT Emergency Repair Disk is shipped with the instrument. Use this disk to restore system setting for your program monitor in case of a major hardware or software failure. Use the following directions to create a repair disk when software is either added or when software is deleted from the PQM300 program monitor.

Operating Information

1. Mark a High Density 3.5-inch disk clearly as the emergency repair disk for

program monitor serial number B01nnnn (the serial number of your program monitor), and then continue with step 2.

NOTE. The emergency repair disk is program monitor-specific. Make sure that the emergency repair disk is clearly marked with its program monitor serial number. The serial number of your PQM300 Program QoS Monitor appears on the original emergency repair disk and on the server rear panel, near the power input connector.

Powering Off the Program Monitor

The normal shutdown procedure for the rack-mounted program monitor without a local user interface or display is with the front panel On/Stby switch. When the program monitor is operating, press and release the On/Stby switch to begin the soft shutdown of the program monitor. Any open processes are closed and files are saved before the operating system shuts down.

If you are operating the PQM300 program monitor with a local UI (monitor or Option LC flat panel display, keyboard, and mouse connected), you can also use the normal Windows NT shutdown procedure (Start ➨ Shutdown) to turn off the operating system. Use the On/Stby switch to restart the program monitor. The PQM300 application restarts automatically. Disconnect the AC power cord at the rear panel to remove power from the instrument.

Emergency Shutdown. You can turn off the program monitor in a emergency or other priority situation by holding the On/Stby button in for about 3 or 4 seconds. This method is a hard shutdown that can cause missing or corrupted files. When the program monitor is turned on again after a hard shutdown, the program monitor does an abnormal shutdown error check.

Operating Information

Shutting Down the PQM300 Application

There are three steps to shutting down the PQM300 application. These steps shut down the user interface, the PQM core program, and the server. The best practice is to use an orderly shutdown procedure so that the appropriate data for the application is saved and all the PQM300 processes are stopped. You must be able to control the program monitor operating system either locally (refer to Local Operation on page 2–9) or through an appropriate network to shut down the PQM300 application using the following steps:

1. In the PQM300 display, click on File in the display task bar and select Exit

to shut down the user interface.

2. Click on the PQM_Core.exe task in the lower task bar to display the task

DOS window. At the prompt, type in exit and press the enter (return) key.

Operating Information

Field Service

If the PQM300 Program QoS Monitor needs repair or adjustment, you may service it yourself or you can have Tektronix service it.

If you have the ability to diagnose and repair module level defects, the service manual will aid you in module-level trouble isolation. Once a problem module is identified, you can order an exchange replacement module. You will then have to install the module, conFigure the mainframe, and calibrate the program monitor as necessary .

If you prefer to have Tektronix or a Tektronix authorized service center diagnose and repair the PQM300 Program QoS Monitor, contact your local Tektronix representative to arrange for either local service or shipment to Customer Service.

A field service or factory service technician performing the repairs will replace the defective module, verify instrument functionality, and ship it back to the customer. Defective modules are returned to a central repair facility for component-level repair where the boards are repaired, tested, and recalibrated if necessary to support the exchange repair program. Refer to Contacting Tektronix in the Preface of this manual for information on obtaining additional customer support.

PQM300 Program QoS Monitor Service Manual

Theory of Operation

The PQM300 Program QoS Monitor is a picture quality measurement instrument. The measurement set system consists of modules that are installed in a standard mainframe platform. The mainframe processor has the capability to make the calculations and data transfers required to do the signal measurements. The mainframe circuitry also provides the power and user interface connections to the installed modules. The measurement set modules accept serial digital video signal input and analyze it for picture quality.

Mainframe Operation

The functional operation is divided between the mainframe and the measurement set modules. The functional description starts with the mainframe and its capabilities. A simplified block diagram of the mainframe is shown in Figure 3–1.

The System Bus is contained in a backplane circuit board, The bus directly connects to all applications modules shown in the block diagram. Full system bus connections to the application modules are provided. Power and control signal connections are provided for all the plug in modules and other modules installed in the mainframe lower compartment.

System Busses

The System Bus contains three sub-busses plus other signal wires: H Power Sub-Bus

This sub-bus carries power and ground to the applications modules.

H Control Sub-Bus

The control bus is a PCI bus.

H Audio Bus

This bus provides a way to route an audio signal generated on any Application Module to the Internal Speaker and the Headphone Jack

PQM300 Program QoS Monitor Service Manual

Theory of Operation

Power Supply

The Power Module consists of the Power Conditioning Board, a purchased power supply, the ac supply connector with line filter, and the power supply cooling fan. The Power Module supplies the PCI bus voltages through the backplane connectors that engage when the module is bolted in place. Other voltages are provided to the mainframe modules through connectors and ribbon cables.

The power conditioning board distributes power from the main power supply to the backplane, to the front panel, and to the SCSI drive connector. The +5 V and +12 V from the main supply are distributed through current limit circuits to meet safety specifications. Voltages to sensitive circuits in the acquisition circuitry are filtered to provide clean voltages. Six additional voltages are generated by dc-to-dc converters on the power conditioning circuit board. These voltages are the +7.5 V, –7.5 V, +3.3 V, +15 V, –15 V, and +33 V supplies. The power conditioning board also does the power on/off switching, generates the line trigger, provides the fan drive voltage, and drives the power good indication circuitry.

A shorted or overcurrent condition on any of the outputs of the main supply will cause a shutdown and cycling of the main power supply. The dc-to-dc converters will foldback for an overcurrent condition and will also cause shutdown of the main supply for a shorted output.

Mainframe Controller

PCI Backplane

Front Panel Interface

The DTI controller is a high-performance PC based controller that includes SVGA graphics and I/O circuitry. The Internal controller mounts vertically at the left of the mainframe card cage and connects into the PCI backplane through a standard 32-bit PCI connector. A 64-bit PCI connector is used for additional I/O communication to the backplane. Interconnection to other instrument components and rear panel ports is through a Processor I/O board.

The PCI backplane supports up to 8 standard PCI modules in addition to the mainframe controller. Custom application modules installed in the module bay provide the PQM300 application features and functionality. The backplane also interconnects the power supply output voltages to the remainder of the system, including the fans. The precision 33 MHz system clock is distributed on the backplane, and all communication to, from, and between the system modules is supported.

The front panel interface assembly interconnects the system controller with the the floppy disk drive, the CD drive, and the mouse, keyboard, and external USB (universal serial bus) ports. The PC speaker audio is also routed from the controller to the speaker through the front panel interface circuit board. The optional mainframe user interface: display, touch panel, and key-pad assembly, are also routed through the front panel interface assembly when installed.

The key pad module has a blank face on the standard PQM300 program monitor. In the PQM300 program monitor with the flat-panel display installed, the key pad and control knob are functional.

The two hard disk drives (HDD) are standard 9 GB SCSI drives that interface directly to the system controller through a Small Computer Serial Interface (SCSI) extension of the PCI bus. The two hard drives are mounted in the Acquisition compartment.

The floppy disk drive is a standard one-half inch drive that supports 3.5-inch,

1.44 Mbyte high density double sided floppy disks.

The CD drive is a half-height drive similar to standard lap top computers. A CD caddy is not needed. The CD drive drawer is manually operated to insert and extract a CD disc from the drive.

Plug in a PS2 compliant mouse and keyboard to the ports at the lower left side (as you face it) of the bezel. These port are interfaced through the front panel processors to the mainframe controller.

LCD Flat-Panel Display

The flat-panel display is an option for the PQM300 program monitor. A backlighted 10.4-inch diagonal Active Matrix Thin Film Transistor (TFT) LCD panel provides the internal color display for the PQM3FLC option. To extend the life of the backlight and prevent burning of the TFT LCD screen, the coldcathode fluorescent backlight can be dimmed to 60% of its maximum brightness with a custom screen-saver or mainframe utilities applet. A DC switching regulator board, included as part of the display assembly, provides the backlight high voltage supply. The LCD display connects to the front panel interface board through a display adapter board in the display assembly.

T ouch Panel. The touch panel is a standard 10.4 inch panel mounted over the surface of the flat-panel display. The touch panel is active at the same time as the mouse. A second front panel processor combines the mouse and touch screen signals to generate and receive standard mouse scan-codes from the system controller.

Program Monitor Module Operation

The program monitor module processes video data using two on-board DSP processors. The module has a PCI interface, two serial digital video input interfaces with active loop-through outputs (Channel A and Channel B), and a serial digital video output interface. The PCI interface is for control, video data, and DSP program code download. The serial digital video interfaces are for real-time capture of digital video.

Blockiness and noise measurements are made on live incoming digital video signals. When blockiness or noise exceeds prescribed levels or durations, an alarm in indicated. The absence of a video signal (missing frames) or frozen video (duplicate frames) is also monitored to indicate abnormal operation.

The program monitor module can output processed program output video in Rec. 601 serial format. The 601 Out connector provides serial digital component video that can be viewed on a high resolution external digital video monitor.

The DSP system is made up of two DSP processors, 256 MB of single-cycle (SDRAM) main memory, a boot ROM, a 64kB shared memory, some control and status registers, a PCI FIFO (first in, first out), and an I/O Video ASIC. Video from the ASIC (application specific integrated circuit) is transferred in 1Kb blocks into memory to form fields.

Theory of Operation

Serial Digital I/O Block

Description

The serial digital I/O system comprises two serial input connectors (Main In and Ref In) and associated deserializers, two serial active loop-through connectors (Main Out and Ref Out) and associated amplifier, a serial output connector (601 Out) and associated serializer, and a clock generator. The Main In, Main Out, and 601 Out connectors are BNC. The Ref In and Ref Out connectors are SMB. A simplified block diagram of the I/O section of the program monitor module is shown in Figure 3–4.

Main In. The Main In connector feeds a cable equalizer through a return-loss

matching network. A carrier detect output from the cable equalizer is fed to the status port so the system can determine if an input is present. The software looks at the carrier detect bits before attempting to use either the Main In or the Ref In input as the signal source.

The output of the cable equalizer drives the active loop-through output driver and the input multiplexer. The other inputs to the input multiplexer are from the other channel and from the output (to allow loopback for self-test).

Only the primary input to the I/O ASIC has timing extraction. There is a 3:1 input multiplexer into the main deserializer. This allows either input to be used in single channel mode with the data coming through the main deserializer. The second deserializer will only be active in two channel mode. If both input channels are being used simultaneously, they must be identically timed and synchronized to the same clock. The third multiplexer input is a feedback from the serializer that is used for diagnostic testing.

Serial to Parallel Converter. The output of the input multiplexer goes to a reclocking circuit that drives a serial-to-parallel converter (deserializer). The serial-to-parallel converter also does the descrambling. The circuit outputs are

parallel video and clock. Source terminations are used in the lines to the buffer ASIC. The clock goes two places, to the I/O ASIC and to the clock multiplexer.

No precision clocks needed in the DSP section; the I/O functions drive the clock source decisions. The input locks to the incoming stream provided it meets SMPTE 259M specifications. There are no circuit provisions made to lock to very jittery input streams or to attenuate jitter on the active loop-through outputs.

27 MHz Oscillator. An internal 27 MHz oscillator is used when there is no external video signal supplied. The 2:1 clock multiplexer is under software control. There are multiple clock outputs to allow each DSP in the module to have a dedicated clock line.

In internal clock mode (also referred to as free-run mode), the program output must meet the SMPTE 259M frequency accuracy and jitter specifications. To meet these requirements, an accurate crystal oscillator is used as the internal clock source. The oscillator is a 27MHz "1ppm TCXO. The oscillator drives the clock multiplexer as one of the two possible inputs. The output of the clock multiplexer drives a clock buffer.

Decoder Valid. Status bits from the reclocking circuit and the serial-to-parallel converter are combined to derive the main decoder valid signal (MAINDECVAL). This signal is checked by the software before attempting to use the clock or video from the Main input. If the system is deriving the clock from this input, and MAINDECVAL goes low, the clock multiplexer automatically reverts to the internal clock source.

Output. The output serializer drives a connected cable directly. One output of the serializer is fed back to the input multiplexer to for use in a loop-back self-test. The program monitor provides a 270 Mb/s serial digital component video output signal at all times when operating. If video content is absent, the 601 output is video black. If no 601 inputs are connected, the output is free running. If a 601 input is connected to either input, the output is synchronized to the input signal. If a 601 input is connected to both inputs, the channel that the output is synchronized with is designated by software control. (The Channel B loop through inputs are not used for the program monitor application.)

PCI Bus Interface

PCI is the bus interface between the plug in modules and the server. The PCI system is made up of a PCI interface chip, 64kB of Dual Port shared memory, a discrete status register, PCI FIFOs, and a PCI control circuit (PLD). The program monitor module can generate interrupts onto the PCI bus. The PCI system can also generate interrupts to the program monitor modules.

Theory of Operation

The PCI system provides setup and control messages to the DSP processors of the program monitor modules through the Dual Port shared memory system. DMA transfers that bypass the Dual Port shared memory can be initiated by the PCI host (mainframe processor) or by the on-board DSP processors.

Boot ROM

Composite Decoder

The Boot ROM is a 4 Mbit Flash EPROM, 8 bits wide. It contains the boot steps used to start up the DSP module when the server is started. The DSP start up diagnostics are contained in the Boot ROM.

The Boot ROM is not programmable on board the module. It is installed in its socket after programming. The programming stored in the Boot ROM performs the following functions:

H Initializes all hardware devices (for example, it resets the I\O Video ASIC) H Initializes the DSP processors H Performs minimal diagnostics:

H Control port read/write H Quick Dual Port Read/Write H Quick SDRAM Read/Write

After the reset, the DSP processors wait for a signal from the server (PCI) to start download operation. Once the download is complete, the DSP vectors to the starting address of the downloaded programming.

The composite video monitor channel is formed by a serial video program monitor module paired with a composite video decoder module that accepts composite video or S-Video and converts it to 601 video at 270 MHz. The decoder block diagram is shown in Figure 3–6. As are the other modules, the decoder is a plug-in circuit board that communicates with the mainframe processor through the PCI bus.

Input

PQM300 Program QoS Monitor Service Manual

The PQM3F01 decoder module input accepts standard level analog video. Input can be composite or S-Video. The input consist of clamping circuitry, buffering, and multiplexing switching. Composite video input is buffered and goes to the Luma output that is applied to the sync stripper. With an S-video input signal, the separate chroma and luma video information are buffered outputs. A calibration signal is applied to the third input to the multiplexer.

The calibration circuitry applies accurate 2 and 3 volt DC levels to the video input circuitry. The FPGA (field-programmable gate array) device averages the resulting values from the converters and compares them to an internal constant. The results of the comparison drives an LED indication circuit to show if the relative A/D output value is high or low. There is also a diagnostic mode signal, a 2-V ramp, that can be applied to the video output amplifiers for testing. Calibration and diagnostics modes are normally manually selected by setting the mode switch on the board. However, when the mode switch is set to the run position, the diagnostics routines can drive the DAC circuitry for closed-loop testing.

The sync stripper ASIC outputs a signal during the sync portion of the video that is used for coarse timing. The input clamp circuit must be running for this sync stripper to work correctly. The chroma output is applied to 2:1 MUX that selects between the S-Video chroma and the chroma stripped from the composite video signal for the color lock circuit. The sync is applied to the FPGA device.

Theory of Operation

A/D Converters

Decoder

FPGA

The analog inputs are attenuated to fill the A/D converter full scale range and are anti-alias filtered for application to the A/D converters. The output of the A/D converters are buffered then decimated by half-band filters before being applied to the decoder device. When converted to 601 format, the standard video input maps into decimal 16 to 235 output levels in 8-bit mode and 32 to 470 levels in 9-bit mode. Signals with lower amplitudes will result in reduced decoder accuracy and signals exceeding the standard amplitude by a certain amount are clipped.

Conversion clocks are derived from a color lock circuit that compares burst from the input to an Fsc (subcarrier signal) developed by a DDS (direct digital synthesizer) device running on the 27 MHz oscillator frequency.

The Ch A and Ch B decoder inputs are 10-bit data from the FPGA. The standard operating mode of the decoder uses an adaptive notch / 3-line comb filter. The field memory stores a field or frame of data used to develop the optional temporal filtering. Luminance data always goes to channel A of the decoder device. Channel B input can be the chrominance (S-Video mode) or delayed luminance for field and frame comb filter modes. The decoder output is fed back to the FPGA device for rounding, dither, and clipping.

The input and output of the decoder device goes to a field programmable gate array (FPGA) device that handles switching, clipping, and dithering to reduce truncation effects. The FPGA device is programmed with the logic to handle the operation of the decoder module. Operating modes of the decoder module are set by filling the appropriate registers on the decoder board through the PCI bus at the time a decoder operation is started.

PQM300 Program QoS Monitor Service Manual

The Chroma portion of the clamped video or the chroma from the S-Video signal is applied to a Color Lock ASIC that controls the phase of the 27 MHz VCO (voltage-controlled oscillator). The VCO output is then used throughout the decoder module as the clocking signal. The 27 MHz clock signal also drives a circuit (DDS - direct digital synthesizer) that develops the Fsc (subcarrier frequency). The Fsc circuit is reset every color frame to correct for any slight frequency errors. The Fsc output completes the phase-lock-loop back to the Color Lock ASIC.

The data bits are serialized in Rec. 601 format and applied to the 601 Out connector on the rear panel of the decoder module. The 601 serial digital signal is externally connected to program monitor input for service quality monitoring.

The PCI Interface circuitry connects the decoder module to the host (mainframe) processor. A programmable logic device contains the logic circuitry to address the chips on the decoder module. Addressing and data transfers to the devices on the module from the mainframe processor is handled by the PCI interface. The PCI interface is configured from the Boot ROM.
