Introduction

The Vela CineCast™ Quad Pro decoder, Model 2000-0422, is an MPEG-2 audio/ video 4-channel deco ding system desi gned for a wide range o f video app licati ons requiring Serial Digital Interface (SDI) video output. The decoder is designed to handle compressed di gital video resolu tions rangi ng from MPEG-1 SIF ( 352×240 pixels) to MPEG-2 digital D-1 4:2:2 video (720×512 pixels). The decoder is designed to be convenien tly mo unt ed i n a st andard 19-i nch equipmen t ra ck, o ccupying one unit of ra ck space. Th e Quad Pro supports Ultr a-2 Fast -40 LVDS SCSI, compatible with single-ended SCSI. The Quad Pro runs under the Microsoft Windows

2000 or Windows NT™ 4.0 operating systems.

An enhanced version of t he Quad Pro, the Model 2000-0422- 1 (“Dash-1”), includes all the features of the Model 2000-0422 and incorporates sev er al oth ers:

• Video Fade: In addition to the au d io fad e/ sw itch a nd vi deo swit ch A/B capabilities of the Cine Cast Quad Pro, this op tion provides the capab ilit y for video fade from or to adjacent channels. Duration of the fade is programmable from 33 msec. up to 5 se conds. The capa bility to fade to a background color between the channel-to-channel fade is also supported.

• Genlock Adjustment: The standard Cine Cast Quad Pro aligns the SDI output with the genlock input. The “Enhanced” Dash-1 version provides the capability of adjusting the SDI output with respect to the ge nlock reference. The Model 2000-0422-2 version of the Quad Pro also supports this same SDI genlock reference adjustment feature.

• Enhanced secondary audio decoder supports MPEG-2 AAC audio.

Unpacking and Mounting

The CineCast Quad Pro 4-Channel Decoder comes packed in a sturdy shipping carton, which contains all relevant hardware, software, cables, and this manual.

1. Carefully un pack the shipping cont ainer and check for damage to the container or its contents.

2. Following electrical safety considerations outlined above, install the decoder unit in a suitable 19-inc h eq uipm ent rac k, insurin g tha t adequa te ventil ation is available.

The following cables are suggested for the CineCast Quad Pro:

• Four video cables with BNC connectors.

• Four genlock cables with BNC connectors.

• Up to eight digital audio output cables with BNC connectors.

• Part No . 60 00- 042 2, audi o out put c a ble wi th ei ght ma le XLR co nnec tors for analog output. Refer to Table 1-6 and Table 1-7 for audio connector pinouts.

Decoder Installation

Page 28

• SCSI interface cable with high-density 68-pin SCSI connector.

• AC power cable (included). Note that if a customer-supplied power cable is used, it mus t be equ al to or exc eed 18 AWG, 1250W, 10A -12 5V.

Depending on whether or not decoder “hot swapping” is required, the installation and removal sequence, SCSI terminat ion cap abil ity, and switch settings will be different.

For an installation where “hot swapping” is not implemented:

• No activity can occur on the SCSI bus while a decoder is being installed or removed (fail ure to adhere to this may cau se the host system to crash and /or may require the host system to be rebooted).

• The decoder’s internal SCSI terminators may be used.

For an installation where decoder “hot swapping” is required:

• Activity between other SCSI Devices is allowed during the installation / removal.

• No bus activity can occur for the decoder that is being installed or removed (failure to adhere to this may cause the host system to crash and/or may require the host system to be rebooted).

• External SCSI bus terminators are to be used.

• “Hot swap” installation and removal procedures are detailed in “Decoder Installation/Removal (Hot Swap),” page 17.

The SCSI Interface

The Vela CineCast Quad Pro decoder connects to the host system through a Small Computer Sys tems In te rf ace (SCSI) interface. This i nterface conforms to the following ANSI standards, except as detailed in this specification. The type of interface is Low Voltage Differential Signal (LVDS) Ultra-2 (Fast-40), which is compatible with single-ended (S E) Ultra (Fast-20) SCS I. Supports Log ical Unit Numbers (LUNs) 0, 1, 2, and 3.

SCSI IDs

Typically, each device on a SCSI bus, including the host adapter, must have a unique SCSI ID. The SCSI ID serves two pur poses:

• It uniquely defines each SCSI device on the bus.

• It determines the d evice’s priority on the bus during ar bitration f or the bus.

Setting the Decoder’s SCSI ID

The SCSI ID of the CineCast Quad Pro Decoder is set via the SCSI ID selector switch located on the rear panel. It should be noted that ID7 is usually reserved for the SCSI initiator (host adapter).

Priority in Arbitrating For the Bus

• Normally, the SCSI initiator (host adapter) is set for SCSI ID 7, which is the highest priorit y.

• Each SCSI device on the bus must have a unique SCSI ID.

• Not all host adapters support SCSI IDs 8–15.

• Some host adapters and operating systems have further restrictions on SCSI IDs for hard disk, CD-ROMs, and tape drives.

• Operating systems and SCSI device drivers may restrict the use of SCSI IDs to SCSI IDs 0 through 7 only.

Bus Termination

The CineCast Quad Pro decod er includ es a selectab le built-in termin ator; however, if “hot swapping” of the decoder is anticipated, an in-line SCSI terminator is recommended. Generally, both ends of a SCSI bus must be terminated.

For systems where only one SCSI cable is used between the host adapter (initiator) and all SCSI devices, the termination is enabled on the host adapter and on the last SCSI device on the SCSI cable.

For systems where two SCSI cables are connected to the host adapter, the termination is disabled on the host adapter. The last SCSI device on each SCSI cable must be terminated.

When mixing both 8-bit and 16-bit de vices consult t he host adapter’s user manual for correct termination requirements.

Decoder Installation

Host Adapter (Initiator) Configuration

The following Ultra-2 SCS I host adapter, based on the PCI bus, is recommended:

• Qlogic Ultra-2 Wide SCSI host adapter, Model QLA-1080.

Note: Adaptec host adapters, such as the Model AHA-2940U2W, have an inherent problem dealing with multiple LUN SCSI devices. This limits their performance and are not recommended at this time.

Uninstalling CineCast Software

If, at some point, you need to uninstall Ci ne Cast dec oder system software, always use the Windows Control Panel > Add/Remove Programs application. Never manually remove any files installed by the installation proc ess, unless specifically directed, as doing so may prevent proper removal of some or all of the files installed. Note that complete removal of the product with Add/Remove Programs is possible only if the produ ct was originally inst alled in the default target folder created by the install process.

In most cases, when you upgrade to version 2.6, you'll be removing a previous version of CineCast software. To uninstall that previous version of software, consult the user's manual that you received when you installed it. At some point, you may need to uninstall CineCast version 2.6 from your system. To do so, just follow the steps below.

• On the software list that is displayed when you select “Add/Remove Programs” from the Control Panel, click on the entry that begins with the phrase “Vela Research, Software Version ….” Then, on the Uninstall Information panel, click OK.

• When asked to select the uninstall method, select “Automatic” and click Next.

• You may see a message indicating that a particular file is no longer being used by any prog r am. Cli ck “Yes to All” to delete it and any other such files.

• On other screens that may appear, Click on Next or Finish until the uninstall process is complete.

• After you click Finish on the last screen of the uninstall procedure, you will be asked to restart the system. Click OK, and allow the system to restart.

When the system has finished rebooting, there should be no file entries in the

C:\Program Files\Vela Research folder. If you find files or folders remaining

in the

C:\Pr ogram F il e s \Vela Research folder, delete them manually.

SCSI Decoder Command Set

This command set f o r t he Vela CineCast Quad Pro decoder f ami l y perf o rm s pe r the SCSI-2 Standard. The Model 2000-0422 and Model 2000-0422-2 decoders use Firmwar e (micr ocode) Re vision Q022. Th e Model 200 0-0422 -1 “Dash-1” vers i on u ses Firmware Revision F022. Any differences in the command set between the two firmware versions will be noted as appropriate. Contact Vela for the latest firmware revision and complete information on the command set, if needed.

SCSI Command Sequence from Power-up, SCSI Reset, or Bus Device Reset

The CineCast Quad Pro decoder will report Check Condition to the first SCSI command (excluding after seeing the check condition, should r espond b y per for ming a

INQUIRY and REQUEST SEN SE). The host adapter (initiator),

REQUEST SENSE.

Per SCSI recommendations, the initiator should renegotiate for syn chronous data transfers and wide transfers. This is done to enable hot swap capabil ity and proper negotiation for Sync and Wide data.

Table 2-1. Command and Status Processing List

The decoder will report Check Condition for all commands except INQUIRY and

REQUEST SENSE from a Power-up, SCSI Reset, or Bus Device Reset.

To enable all commands, the following sequence must be performed:

INQUIRY TEST

UNIT READY (Will report check condition )

REQUEST SENSE TEST

UNIT READY (Optional, will report Good status)

This command sequence is typically performed automatically by the SCSI host adapter (initiator) during power-up. Following the above sequence, all decoder commands will be active.

SCSI Command Description

The following command descriptions contain de tailed information on the SC SI commands that are supported by the CineCast Quad Pro decoder.

Command fields within SCSI Command Descriptor Blocks are supported as follows:

Logical Unit Number (LUN)

Ignored by the decoder. Per SCSI-2 recommendations this field should be set to

0. This field was used for SCSI-1 devices, but is now reserved. SCSI-2 requires Logical Unit Number to be specified in the Identify message, not in this field.

Reserved

Reserved bits, fields, bytes, and code values are set aside for future standardization and must be set to zero. If the decoder receives a command that contains non-zero bits in a reserved field or a reversed code value, the command is terminated with a Check Condition status. The sense k e y (read via a is set to

ILLEGAL REQUEST.

INQUIRY Command (OpCode 0x12, 6 bytes)

The INQUIRY command allows the initiator (host adapter) to determine the kind of SCSI devices attached to its SCSI Bus. It causes a device that is attached to a SCSI bus t o re turn information about itself. Si nce the function of t he SCSI decoder does not fit into any of the standard SCSI device types, a new device type has been defined. The function of the MPEG decoder is similar to a Direct Access Storage Device, e.g., a hard disk, but also has characteristics of a CD-ROM. The MPEG decoder can be viewed as a write-only device.

The decoder can provide two categories of data in response to an

INQUIRY com-

mand: Standard Inquiry Data and Vital Product Data. Standard Inquiry Data contains basic data about the decoder, and Vi tal Product Data comprise several pages of additional data. Each Vital Product Data page requires a separate

INQUIRY command from the in itiator.

MPEG PLAY Command (OpCode 0xA5, 12 bytes)

This is an OpCode taken from the CDROM PLAY AUDIO (12) command which is used to start decoder playback. This command is the primary mechanism for controlling decoder playback.

NTSC frame rate is 30 frames per second (29.97Hz Frame Rate). PAL frame rate is 25 frames per second (25Hz Frame Rate).

Following power-up, the CineCast Quad Pro checks the state of an input discrete (SMU connector, 15-pin D-Sub on pin 7). If the discr ete is open , the defa ult video standard is NTSC. If the discr ete is cl osed (connect ed to ground ) open, the default video standard is PAL. To change between video standards, decoder (45h) command with command code 001Bh must be used.

Table 2-8. MPEG PLAY Command Format

Error Recovery on Data Under Flow (ErrRcvy)

Determines how the decoder handles a data starvation condition. When set to zero (default), and when the decoder uses up all data in the DRAM buffer, the decoder will end playback and force the screen to black. This happens when the

MPEG PLAY Command

Page 74

60 CineCast Quad Pro Version 2.6 In stallation and User M anual

host is not sending data fast enough to keep up with the playback rate. This is a fatal playback error, in which the decoder is informing the host system that playback has stopped. The decoder will return the following on the next

SCSI Status Check Condition

Additional Sense Code and Qualifier 0005h End-of-Data Detected

RESET BUFFER command, new data [via WRITE (10)], and a new MPEG PLAY

WRITE (10):

command are required before playback can start again. When set to 1, the decoder will automatically enter a Pause state when the

decoder detects that the DRAM buffer is empty. The decoder will wait for eight 64-K buffers to be filled before resuming playback. This mode requires that a

RESET BUFFER be sent at the end of a stream, so the decoder knows the differ-

ence between the data underflow and the end of a stream. Also, the decoder keeps a count of the number of times this data underrun condition occurs. Refer to Mode Page (30h).

Mid-Stream Start (Midstrm)

By setting this bit to 1, the de coder wil l auto matically find the first valid sequence header before starting playback. This allows the start of playback in a random position within an MPEG file. (This feature may delay video start-up by a few frames. The end result will be more black between back-to-back videos.)

Autodetect must be used with mid-stream starts. By setting this bit to 0, the decoder assumes that the MPEG stream begins on a valid sequence header.

Automatic Pause on First Visible Frame (Pause)

When this bit is set to 1, the decoder begins play back, but automatically pauses on the first non-black video frame. This depends on the value of Pre-Black. Once paused, use the pause. Alternatively, the

DECODER (45H) command with code 0012h to resume from

FRAME ADVANCE (010F) command can be used to

advance one video frame.

Trigger

When this bit is set to 1, the decoder waits for the trigger event (as defined in Trigger Event) to occur before beginning playback.

MPEG-2 Audio PES 22h

NOTE: All other stream type codes are reserved.

Autodetect

If the stream type is set to 00h, the decoder will parse the beginning of the s tream to determine stream type. The decoder can detect:

• MPEG-1 System stream

• MPEG-2 Program stream

• MPEG-2 Transport stream

• Audio/Video PES

• Video Elementary stream

• Film Mode (24 frames/second; 3:2 pull-down)

• NTSC/PAL

• MPEG Chroma Format 4:2:0 / 4:2:2

Pre-Black

8-bit pre-black interval in video frames. A value of 0h uses default pre-black (first frame). To display the first frame of video with no pre-black frames, set a value of 1.

Frame Count

32-bit frame count in video frames. Video and audio will play back for this specified number of frames. A value of 0h plays in non-frame count mode.

Post-Black

16-bit post-black interval in video frames. A value of 0h uses the default of eight frames. In Single pla ybac k mode , this field speci fies the minim um n umber of b lac k frames until starting the next play. A value of 0h uses the default of eight frames.

In Switched playback mode, this field represents the amount of black which is

inserted between the switched playback. A value of 0 means no black is inserted before changing channels.

Trigger Event

When Trigger = 1, this field determines which event will start (trigger) the playback.

Trigger Source

Value

0000b Hardware trigger using GPIN1 (default)

0001b Hardware trigger using GPIN2

0010b Trigger on LTC input match (used in conjunction

with Set Time Code 0004h command)

0100b Trigger when adjacent channel playback complete

Source Event

To cancel a pending Triggered Playback, use the Stop command (decoder command 45h with command code 0023h). To override the Triggered Playback, send the command “Resume from Pause” (0012h). This will cancel the wait for trigger and force playback to begin immediately.

For a Hardware Trigger based on either GPIN1 or GPIN2, the decoder waits for the trigger discrete input (GPIN1 or GPIN2) to be closed (grounded) before beginning playback.

These inputs are located on the two 44-pin connectors as shown in Table 1-6, “D-Sub Connector Pinout, J13,” on page 39, and Table 1-7, “D-Sub Connector Pinout, J25,” on page 41.

Chroma Format Select (Chroma)

The IBM decoder hardware uses two different loads of microcode depending on the application. One strictly plays 4:2:2 chroma format streams and is optimized for high bit rate streams (>25Mbps). The other plays 4:2:0 or 4:2:2 chroma format. Normally the firmware selects the appropriate MPEG microcode, but the host can override.

Command Code Description

0000 Soft Reset, Audio/Video: This command perf orms a r eset of the audi o and video circuits and forces the screen to black or selected background color.

0004 Set Time Code: This command passes a SMPTE time code to the decoder for use with a subsequent command. The time code is defined in the 32-bits of data as shown: This command has four different uses:

Table 2-10.Time Code Command Description

• Set User Defined starting t ime code (used in place of GOP hea der time code):

1. Send “Set Time Code” (command 0004h) with specific starting time code.

2. Send “LTC/VITC Time Code Configuration” (command 0005h) command with bits 11&10=01b.

DECODER Command (45h)

Page 84

70 CineCast Quad Pro Version 2.6 In stallation and User M anual

• Set Trigger Playback on specific I nput LTC time code:

1. Send “Set Time Code” (command 0004h) with trigger time code.

2. Send “MPEG Play” with fields “Trigger”=1 and “Trigger Mode”=010b (Trigger on LTC input match).

• Modify Start Time: Allows the Playback start time to be modified when using Play on Input

LTC time code. When a Pla y on Input LTC time code trigger is queued or pending, the start time can be modified by sending this commend with byte 4 bit 1 set.

• Execute an Inline trick mode (e.g., Pause or Stop) at a specific time code:

1. Send “Set Time Code” (command 0004h) with specific time code.

2. Send decoder command (such as Stop or Pause) with fields “Inline” = 1 and “Inline Mode” = 011b.

0005 LTC/VITC Timecode Configuration: This command configures the LTC output.

0008 Set Audio Gain: Each audio output has an adjustable gain control from +12dB to -84dB. The host must pass a gain value in dB. The parameter passed to the firmware is the gain in dB times 16, giving a resolution of 1/16 dB. The host passes a 12-bit signed (two’s complement) value of the gain for both the primary and secondary outputs. 32-bits of data are used to pass the gain parameter.

• Byte 4 & 5 — Primary Audio Gain

• Byte 6 & 7 — Secondary Audio Gain

Gain Parameter

(Gain x 16)

Any gain value requested which is outside the valid range will be limited to +12dB to -84dB. When a value of 0dB is requested, the firmware will use the bypass mode provided within the FPGA. Default power-up gain is 0dB, which provides unity gain from Vela Encoders through the CineCast Quad Pro.

Bits 8 and 9 of the command determine the analog headroom of 18dB or 20dB. This only effects the analog outputs and does not affect the digital/embedded audio. Default is 18dB headroom, matching Vela audio/video encoders.

Command Bits Function Name Comments

Bit 8 Primary Headroom 0 = 18dB Headroom

Bit 9 Secondary Headroom 0 = 18dB Headroom

000C Slow Motion: This commands slows the playback rate. A three-bit f i eld (bits 8-10 of the command) determines playback speed.

Bits 10–8 Playback Speed

001b Slower rate (each frame is displayed twice)

111b Slowest rate (each frame is displayed eight times)

Use command 001Ah to resume normal playback rate. This mode is reset on a new playback .

000D Fast Forward: This command increases the playback rate. The decoding hardware will only display the I frames from the MPEG stream, skipping all B and P frames.

Use command 001Ah to resume normal playback rate. This mode is reset on a new playback.

NOTES: (1) Fast Forward increases the playba c k rate w hich increases the decode r's demand for data, so the syste m m ust be c apable of handling this increased throughput.

(2) Bit rates highe r than TBD Mbps ma y exhibit break-up and data under flo w problems. (4) An MPEG stream comprised of only “I” frames cannot be fast forwarded.

3) The Fast Forward command cannot be sent within the first second of playback.

000E Closed Capt ioning Reorder: Closed Captioning data in NTSC MPEG streams is contained in the User Data associated with each picture. CC data can be presented in either bit stream order or display order.

Command Bits Comments

Bit 8 0 = Bit stream order. CC is received in the same order it is

received (default). 1 = Display order. CC data is reordered based on its tem-

poral reference of the associated picture.

Bits 15–9 Reserved

000F Pause Video/Frame Advance:

Pause (000F h): Stops playback on current frame, freezing the video image.

Use Resume command to resume playback. Frame Advance (010Fh): Once in pause mode, sending the Pause command

with bit 8 set will frame advance the number of video frames indicated in the 32 bits of data. When the 32 bits of data is 0 or 1 the decoder will frame advance by 1 video frame.

DECODER Command (45h)

Chapter 2 — Overview and Operation 73

NOTES: (1) The Pause command cannot be sent within the first second of playback. (2) Once the decoder has been Paused, additional MPEG data (via the write 10 com-

mand) should not be sen t. If all the MPEG b u ffers become full while i n Pause, the ne x t write 10 will never complete. T his us ua lly res ul t s in a SCSI c om ma nd t im eou t from th e host adapter (initiator) which causes a Bus Reset.

W hen Frame Advance is u se d, the decoder will require additional MPEG data when advancing many frames.

0010 Freeze Frame: Freezes the video image, but the decode continues in the background. Use Resume command 0012h to resume playback.

0011 Flush Chann e l Buffe r: Stops playback after all data in the decoder’s buffers is used. Equivalent to

RESET BUFFER (0021h).

0012 Resume Play (from Pause): Resumes playback after a pause. 0013 Mute Audio: Mutes the audio output. 0014 Unmute Audio: Unmutes audio output. Disabled during Fast For ward,

Slow Motion, Pause, and Freeze Frame.

0015 Set Stand-Alone Mode (Genlock Disable): Default mode of the decoder. 0016 Set Genlock Mode: This enables the decoder to synchronize to the gen-

lock input source.

• Bit 8 of the command is reserved.

• Bit 9 of the command allows for automatic switching to Standalone mode upon detection of loss of genlock.

• Bits 10-11 is genlock source selection.

• Bits 12-15 of the command is reserved.

Bit 9 Loss of Genlock, switch back to Standalone

0 Feature disabled (default)

1 Enables feature. When the decoder detects a loss of genlock,

the decoder will automatically switch back to standalone mode.

This feature requires that Error Reporting be enabled, i.e., decoder (45h) command, command code 002Bh, with bit 10 set to 1 to enable Genlock Loss reporting. When genlock input is not detected during playback, the decoder will switch back to Standalo ne m ode and re turn th e following error: Recovered

The decoder from that point on will remain in Standalone mode until genlock mode is re-enabled by the host.

The genlock hardware requires a genlock resync, which results in a momentary picture glitch, jump, or white flash when genlock mode is first enabled. The genlock resync will occur 3–4 seconds after one of the following conditions:

1. The first time the decoder is put into genlock mode (via the Genlock command 0x0016).

2. When genlock is en abled and th e vide o stand ard is change d, i.e. , when changing between NTSC and PAL.

3. After a loss of genlock. The genlock resync will occur upon reacquisition and detection of the genlock signal.

Genlock Source Selec t ion: The CineCast Quad Pro allows each decoder channel's genlock source to come from one of three possible sources. This gives the ability to lock one, two or four channels together to a genlock source.

NOTE: The above command must be used to switch the decoder between NTSC and PAL video when not using “Stream Auto-dete ct ” mod e in the MPEG PLAY command.

001D Flush Inline Commands: Commands which are sent as “inline” can be flushed by sending this command.

0021 Buffer Reset/Pause on Last Frame: Used in the playback sequence to reset the MPEG buffer pointers before starting download of MPEG data to the decoder. This can also be used to end playback after all data in the decoder’s buffers are used. When bit 8 of the command is set, the decoder will freeze frame on the last decoded picture of the MPEG stream.

0023 Stop/Stop with Freeze Frame: Stops video playback.

0023 Stop: Forces the screen to black at stop. 0123 Stop: Freezes frame of last image at stop.

0024 Set Frame Count: This command is sent before an “inlined” decoder

command, such as Stop or Pause, to set the desired frame count. The 32-bits of data contain the desired frame count.

• Sequence to execute an inlined decoder command on a specific

frame count:

If an MPEG stream contains only a single MPEG audio track, the IBM audio decoder will decode it. The secondary audio decoder will remain idle. The audio switching circuitry can be utilized to output the audio channel on both outputs.

If an MPEG stream contains two MPEG audio tracks, the first stream ID/PID is sent to the IBM decoder; the second stream ID/PID is sent to the CS49xx audio decoder.

The two output discretes are located on the two 44 pin connector. Each channel also has a relay contact closure (called Playback Active or Tally output) which is activated while playback is active.

003B Video Switch: This command controls the vertical interval video switch between channel pairs. Set bit 8 of command (i.e. 013Bh) to force the video switch (the switch to occur on the next vertical sync). Video switching requires both channels to be genl ock ed to the same genl ock sou rc e. Comman d 003Ch can be used to switch both audio and video. The 32 bits of data determine which output channel is selected:

32-Bit Data Video Source

0 Selects MPEG video output

1 Selects MPEG video output of adjacent channel pair

If genlock is not va lid on both chann els when switching video, the command will be ignored and the following error will be returned: “Recovered Error, Genlock Sync Lost.”

This command sets de fault PSI table values.

• PID type is specified in the upper eight bits of the command.

• PID value is specified in the 32-bit data field.

• ID is 16 bits for program number 13 bits for transport PID.

7 Secondary Channel Audio PID

Current default values are 0x10 (video), and 0x11 (primary channel audio). Defaults may be changed by the Se t Transport PID command. These values will stay set until they are changed by another Set Transport PID command.

To use values specified by the PSI ta bles in the stream (specified in the Transport PMT packet), set t he aud io and v ideo PIDs to zero. Values may be changed at an y time and become effective immediately even during playback.

A soft reset command will set the audio and video PIDs to zero, thus PID values will be pulled from th e PSI tables in the stre am.

003E Set Frame Freeze: This command allows the user to select frame freeze vs. field freeze when using the “Pause” or “Pause on Underrun.”

• 003E – Pau se w it h Field Freeze displays the same data in both video

fields to prevent frame jitter. This is the default.

• 013E – Pause with Frame Freeze displays both fields.
