Introduction
The Vela CineCast® HD series of high-definition decoders are SCSI-based
MPEG-2 audio/video decoders designed for High Definition Television
(HDTV) applications. Such applications include broadcast, post production,
advertising and other video distribution applications; large-format point-ofinformation applications (such as those found in large theme park and sports
venues) using new plasma display technology and new-generation 16:9 display
devices and projection systems; high-resolution output such as e-cinema; HD
content repurposing; and digital archiving applications.
Examples of CineCast HD users are HD production facilities needing an
upstream decoding device for studio signal monitoring or to feed downstream
HD switchers and routers or HD DVE equipment. Another end use example
would be that of a movie theater requiring decoders for e-cinema applications.
The CineCast HD version 1.0 series of decoders come in one-channel (Model
HD/1) and two-channel (Model HD/2) models designed to be conveniently
mounted in a standard 19-inch equipment rack, occupying one rack unit of
space. The CineCast HD is also available in a standalone board version,
Model 2000-2165.
Features such as genlock capability, a 2x1 A/V switcher, redundant power
supplies, triple stereo AES audio, two to six channels of SMPTE 299M digital
audio, AAC and MPEG audio, Dolby Digital (AC-3) bitstream out, and dual
analog stereo audio make the CineCast HD ideal for high-end professional
applications. In addition, SMPTE 337M AES/EBU compressed bitstream output is
supported. Each decode channel supports individual LTC time code outputs. The
HD supports one General Purpose Interface (GPI) input and output per channel.
The CineCast HD is fully ATSC compliant, supporting all 18 ATSC modes. It
provides LTC time code output support and VIP 2.0 over-the-top video bus for
VGA display of HD resolution video. It also implements the Vela Media Bridge
bus, designed to work in conjunction with another CineCast HD decoder for
switching functionality.

2 CineCast HD Version 2.6 Installation and User Manual
Every effort has been made to maintain software compatibility with the existing
CineCast SCSI family system software. The current release is version 2.6. The
CineCast HD operates under Windows 2000, Windows NT 4.0, and Solaris.
The CineCast HD is built around the TeraLogic TL850 and TL855 HD decoder
chips. The primary differences between the TeraLogic TL850 and TL855 HD
decoder chips is that the TL850 supports only 4:2:0 HD profile decoding while it
offers a broad range of SD to HD, HD to SD, and HD to HD scaling capabilities.
The optional TL855 offers 4:2:2 profile SD and HD playback.
The CineCast HD incorporates some technologies from the existing CineView Pro
XL and CineCast Quad Pro decoders, namely the SCSI Ultra-2 LVDS interface, the
VIP 2.0 interface, transcode bus, AC-3/AAC audio, and miscellaneous I/O components. In addition, the CineCast HD introduces a number of new features and
capabilities not found in other Vela products, including the use of the Teralogic
TL850 and TL855 decoders.
A primary design goal has been to support the CineCast HD as a subset of an
expanded CineCast Quad Pro API. This provides existing customers an immediate upgrade path to the CineCast HD from the CineCast Quad Pro, the CineCast Quad, and the CineCast Prime decoder products.
Configuration
The CineCast HD SCSI decoder is designed to interface to a SCSI Ultra-2
Fast-40 LVDS (or SCSI Ultra-Fast-20) single-ended interface. A sketch of the
decoder, along with pinouts of audio connectors, and views of the front and
back panels, is provided at the end of this chapter.

The SCSI Interface
The Vela CineCast HD decoder connects to the host system through a Small
Computer Systems Interface (SCSI) interface. This interface 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 (SE) Ultra (Fast-20) SCSI.
American National Standards Institute SCSI Standards
SCSI-3 Architectural Model (SAM) X.3.270:1996
SCSI-3 Interlocked Protocol (SIP) X.3.292:1997
SCSI-3 Primary Commands (SPC) X.3.301:1997
SCSI-3 Parallel Interface (SPI) X.3.253:1995
SCSI-3 Parallel Interface-2 (SPI-2) X.3.302:1999
SCSI-3 Fast-20 Parallel Interface (Fast-20)X.3.277:1996
SCSI IDs
Typically, each device on a SCSI bus, including the host adapter, must have a
unique SCSI ID. The SCSI ID serves two purposes:
• It uniquely defines each SCSI device on the bus.
• It determines the device’s priority on the bus during arbitration for the bus.
Setting the Decoder’s SCSI ID
The SCSI ID of the CineCast HD decoder is set via the SCSI ID selector switch
located on the rear of the board or on the rear panel of HD/1 and HD/2 models. It
should be noted that ID7 is usually reserved for the SCSI initiator (host adapter).
On HD/2 decoders, a unique ID should be set for each of the two boards
Priority in Arbitrating For the Bus
• Normally, the SCSI initiator (host adapter) is set for SCSI ID 7, which is the
highest priority.
• 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.
Decoder Installation
Page 22
12 CineCast HD Version 2.6 Installation and User Manual
Bus Termination
A terminator switch is located on the rear of the decoder board. Setting the switch
to the left position (farthest away from the connector area) enables termination.
Model HD/2 decoders should have termination enabled on only one of the two
boards contained within the unit, per general SCSI procedures.
Host Adapter (Initiator) Configuration
The following Ultra-2 SCSI host adapters, based on the PCI bus, are recommended:
• Qlogic™ Ultra-2 Wide SCSI host adapter, model QLA-1080.
• Adaptec™ 29160 Ultra 160 host adapter.

Jumper Information
See Figure 1-22 for jumper locations on the HD circuit board. Most jumpers
should be left in their factory default positions.
In case of a corrupt firmware, situation, Jumper JP6 will need to be reconfigured
from its default 16-bit boot mode to an 8-bit boot mode to enable recovery of
firmware settings. See Figure 1-2 for default and firmware recovery setting.
Jumper JP9 indicates the primary Vela Media Bus decoder board. In board-only
and Model HD/1 versions, the jumper is normally open. In the case of HD/2
models (with two boards), one and only one of the two boards should have this
jumper enabled. See Figure 1-2 for primary VMB jumper placement.
Connector Locations and Pinouts
Refer to Figure 1-22 to locate and identify the various connectors, switches and
jumpers that populate the CineCast HD decoder board. Two BNC connectors
are provided for digital video output and genlock input. Connector P1 is a
Molex brand “Microcross” (P&D) multi-functional connector through which
the decoded signals are output.
CineCast HD Multi-Output Cable Assembly
Figure 1-24 is a representation of an accessory multi-output cable that can be
purchased from Vela to facilitate easy connection of the CineCast HD decoder.

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 detailed information on the SCSI
commands that are supported by the CineCast HD 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 key (read via a
is set to
ILLEGAL REQUEST.
REQUEST SENSE)
Control
The control byte is the ending byte of all SCSI Command Descriptor Blocks and
has the following format:

Table 2-2. Control Byte Format
NOTE: The control byte of each SCSI command must be zero. Linked commands are
not supported by the decoder.
Page 55
Chapter 2 — Decoder Command Set Guide 45
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 to return information about itself. Since the function of the 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 Vital Product Data comprise several
pages of additional data. Each Vital Product Data page requires a separate
INQUIRY command from the initiator.
Table 2-3. INQUIRY Command Descriptor Block
EVPD
Enable Vital Product Data. If 0, the decoder returns the Standard Inquiry Data
page; if 1, the decoder returns the Vital Product page specified in Page Code.
Page Code
Specifies the Vital Product Data page to be returned.
Allocated Length
Specifies the number of bytes of inquiry
information to be returned to the initiator.

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.
The power-up default video resolution is the last selected resolution. To change
resolutions, decoder (45h) command with command code 001Bh must be used.
MPEG PLAY Command
Page 61
Chapter 2 — Decoder Command Set Guide 51
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
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
WRITE (10):
SCSI Status Check Condition
Sense Key 03h Medium Error
Additional Sense Code and Qualifier 0005h End-of-Data Detected
RESET BUFFER command, new data [via WRITE (10)], and a new MPEG PLAY
A
command are required before playback can start again.
When set to 1, the decoder will automatically enter a Pause state when the
MPEG PLAY Command
Page 62
52 CineCast HD Version 2.6 Installation and User Manual
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 decoder will automatically 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 playback, 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.
Trigge r
When this bit is set to 1, the decoder waits for the trigger event (as defined in Trigger
Event) to occur before beginning playback.
Stream Type Hex Code
Autodetect 00h
MPEG-2 Transport Stream 28h
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 stream
to determine stream type. The CineCast HD decoder currently only supports
MPEG-2 Transport streams.
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.
NOTE: The CineCast HD does not currently support pre-black.
MPEG PLAY Command
Page 63
Chapter 2 — Decoder Command Set Guide 53
Post-Black
16-bit post-black interval in video frames. A value of 0h uses the default of eight
frames. In Single playback mode, this field specifies the minimum number of black
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.
NOTE: The CineCast HD does not currently support post-black.
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.
NOTE: The CineCast HD does not currently support frame count.
Trigge r 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 (VMB)
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. GPIN2 is located on the Vela Media Bus (VMB).
DECODER Command (45h)
(OpCode 0x45, 10 bytes)
This is an OpCode taken from CDROM PLAY AUDIO (10), which is used to control
decoder operation. This OpCode is for experienced users who desire additional
control over the decoder’s operation. Format of the command is:

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 time code (used in place of GOP header time code):
1. Send “Set Time Code” (command 0004h) with specific starting
time code.
2. Send “LTC Time Code Configuration” (command 0005h) command
with bits 11&10=01b.
• 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 Timecode Configuration: This command configures the LTC output.

0008 Set Audio Gain: Each audio output has an adjustable gain control from
0dB to -128dB. 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
DECODER Command (45h)
Page 70

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
0dB to -128dB. Default power-up gain is 0dB, which provides unity gain from
Vela encoders through the CineCast HD decoder.
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.

Bits 10–8 Playback Speed
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- and P-frames from the MPEG stream, skipping
all B-frames. Use command 001Ah to resume normal playback rate. This mode is
reset on a new playback.
NOTES: (1) Fast Forward increases the playback rate, which increases the decoder’s
demand for data; therefore, the system must be capable of handling this increased
throughput.
(2) Bit rates higher than 40Mbps may result in break-up and data underflow problems,
forcing a return to Play mode.
(3) An MPEG stream comprised only of I-frames or IP-frames cannot be fast-forwarded.
000F Pause Video/Frame Advance:
Pause (000Fh): 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.
NOTE: Once the decoder has been Paused, additional MPEG data (via the write 10
command) should not be sent. If all the MPEG buffers become full while in Pause, the
next write 10 will never complete. This usually results in a SCSI command timeout from
the host adapter (initiator) which causes a Bus Reset. If more MPEG data is sent, the
application must check Mode Page 30h (via mode sense command) to be sure there is
sufficient room in the MPEG buffers (bytes 14 and 15). When Frame Advance is used,
the decoder will require additional MPEG data when advancing many frames.
0011 Flush Channel Buffer: 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 Forward,
Slow Motion, and Pause.

• Bits 10-15 of the command are 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 Standalone mode and return the following error:
Recovered
Error, Genlock Sync Lost.
SCSI Status Check Condition
Sense Key 01h
Additional Sense Code and Qualifier 6100h
Additional Sense Bytes 18 & 19 0107h
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 enabled and the video output resolution is changed.
DECODER Command (45h)
Page 73
Chapter 2 — Decoder Command Set Guide 63
3. After a loss of genlock. The genlock resync will occur upon reacquisition and detection of the genlock signal.
001A Resume from Slow or Fast Motion: This command is used to restore
normal playback rate after Slow or Fast Motion.
001B Output Resolution Setup: This command is use to select the output video
resolution from the various HD resolutions available 1080i, 720p, 480p, and
480i. The HD decoder hardware provides up-conversion and down-conversion of
source video (MPEG stream) to the selected display format. The CineCast HD
provides Serial Digital, Analog HD RGB or YPbPr, and a down-converted analog
composite SD output. The upper 8-bits of the 16-bit Command (0x001B) are not
used. Three fields within the 32-bit data define the Display Group, Display Timing, and HD Analog Video Output Type.
Table 2-11.Output Resolution Setup Command Description
Display Group
Allows the choice of one of 15 display groups. See table below.
Display Timing Parameter
Allows the choice of one of several format resolutions within the display group, see
the table that starts on the next page. The most common ATSC resolutions are:

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:
1. Send command 0024h “Set Frame Count” with the 32-bits of data set
at desired frame count.
2. Send decoder command (such as Stop or Pause) with fields Inline = 1
and Inline Mode = 011b.
0026 Film Mode (24 frames/second): This command is ignored by firmware,
as it is no longer required. Film mode is automatic.
0029 IIC Register Address Setup: Used in conjunction with command 002A to
allow the user to customize various parameters of the output NTSC/PAL video
encoder. Also provides IIC access to a Serial EEPROM. The 32-bits of data are
defined as follows:
32-bit Data Function
13–15
(Device Select Bits)
8–12
(Command Bits)
0x0 — 7121 (Video Encoder)
0x1 — Serial EEPROM (reserved for factory use only)
0x06 — Register Write
0x07 — Register Read
0–7
(Register Number)
DECODER Command (45h)

Page 81
Chapter 2 — Decoder Command Set Guide 71
002A IIC Data: Used after command 0x29 has been issued. Data to be written
is specified in the 32-bit data field. On a “Register Write” command, the decoder
will write the value supplied in the lower byte (in byte 7) of 32-bit data into the
device and register specified in command 0029h.
Digital Video Encode Adjustments
Adjustments can be made to the composite video output by changing register values within the Philips SAA7121 NTSC/PAL video encoder. Consult Philips
Semiconductor SAA7121 Data sheet for the “SAA7120; SAA7121 Digital Video
Encoder (ConDENC)” dated 1997 Jan 06, for complete register definition and bit
definition. Video adjustments require the use of decoder command 0x0029 and
0x002A.
Provided adjustments:
• Chrominance Phase (Register 0x5A)
• Gain U (Register 0x5B)
• Gain V (Register 0x5C)
• Black Level (Register 0x5D)
• Blank Level (Register 0x5E)
The 0029/002A commands only provide write access to the SAA7121 registers,
register values cannot be read back. Only one status byte can be read back.
The register values must be reloaded after the following events:
• Power is cycled.
• SCSI Reset or Bus Device Reset occurred.
• Changed between different video standards (PAL/NTSC)
Chrominance Phase (Register 0x5a): Phase of encoded color subcarrier (including burst) relative to horizontal sync. Can be adjusted in steps of 360/256 degrees.
Gain U (0x5B): Variable gain for Cb signal; output subcarrier of U contribution,
input representation in accordance with “CCIR 601."
Gain V (0x5C): Variable gain for Cr signal; output subcarrier of V contribution,
input representation in accordance with “CCIR 601."
Black Level (0x5d): Variable black level; input representation is in accordance
with CCIR-601 standard.
Blank Level (0x5e): Variable blanking level.

Serial EEPROM Access
The CineCast HD includes an Atmel AT24C02 (256 x 8) Serial EEPROM. Access to this serial EEPROM is reserved for factory use only.
To write a value to Serial EEPROM, write value 0xAA to address 0x55:
• Decoder Command 0x0029 with 32-bits data = 0x00002655 (write address
0x55)
• Decoder Command 0x002A with 32-bits data = 0x000000AA (write value
0xAA to register 0x55).
To read a value from Serial EEPROM:
• Decoder Command 0x0029 with 32-bits data = 0x00002701 (read address
0x01)
The read data is returned in Mode Page 0x30 in the “Decoded Frame Number” (in
the lower byte, byte 11) for the first access to mode page 0x30 after an IIC Read
command.
002B Error Mask: Used to enable/disable error checking for MPEG stream
decoder errors, audio/video channel buffer errors, and loss of genlock errors.
By default, all these errors are masked (disabled). The 32-bits of data contained

PID Type Operation
7 Set Secondary Channel Audio PID
By default the decoder uses the PSI tables in the stream to play the first Program
found in the stream. This command can be used to force the decoder to play
different program numbers and different audio/video PIDs. This requires this
command to be sent three or four times to set the required PSI information:
1. Set Program Number. Command is 0x013D and the Program Number will
be the lower 16-bits of the 32-bits data field. The Program Number will
specify which program to decode in a Multi-Program Transport Stream.
2. Set Video PID. Command is 0x053D and the Video PID will be the lower
13-bits of the 32-bits data field.
3. Set Primary Channel Audio PID. Command is 0x063D and the Audio No. 1
PID will be the lower 13-bits of the 32-bits data field.
4. Set Secondary Channel Audio PID. Command is 0x073D and the Audio No.
2 PID will be the lower 13-bits of the 32-bits data field. (Optional when
transport stream contains more than one audio stream.) Set PID value to 0 if
not using second channel audio.
To restore the default mode where the decoder automatically parses the PSI tables, set the Program Number to zero. Command is 0x013D, and 32-bits data is 0
(Program Number = 0).
Values may only be changed before a playback begins.
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 – Pause with 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.

0047 Video/Audio Fade
This command provides audio and video fading and switching capability. The
command offers video fade down from video source A to background then fade
up to video source B, with a maximum fade time of 255 frames. Video/Audio
switching is accomplished by setting the fade time to 0 or 1.
Fading and switching requires two CineCast HD decoders connected together via
the Vela media bus cable inside the chassis. Both decoders must be genlocked to
the same video source.
To implement an audio/video switch/fade two commands need to be sent:
• The first command needs to be the Fade Up and is sent to the current nondecoding channel. This command should be sent as an inline command
triggering on GPI2. The Fade Down command will automatically set GPI2.
• The second command needs to be the Fade Down and is sent to the current
decoding channel.
Either of the two decoders can be the primary decoder. The primary decoder is the
decoder that has the audio and video cables attached and whose audio/video output is being monitored. The other decoder is called the secondary decoder.
This command is also used to setup the audio routing on each decoder. To set
routing without performing a switch/fade simply clear the “Video Fade enable”
and “Audio Fade enable.”
Table 2-13.Video/Audio Fade Command Format
Video Fade Enable
This bit must be set to enable video fading operation. When cleared, no video
switch or fade will occur.

Video Source
This selects the new video source:
Video Source Video Selected
0b MPEG Video Decoder Output
1b Video from the Vela Media Bus Output
NOTE: Video Switching/Fading requires both channels to be Genlocked to the same
Genlock source. If Genlock is not valid on both channels when switching video, the
video switch will be ignored and the following error will be returned:
RECOVERED ERROR, GENLOCK SYNC LOST
SCSI Status Check Condition
Sense Key 01h
Additional Sense Code and Qualifier 6100h
Fade to Black
This field is reserved, Fade to Black (background) is the only supported fade
operation.The current video source will fade to black (or background color) and
then fade from black (or background color) to the new video source. Background
color is specified in command 0033h.
Fade Down/Up
Used to determine the direction of the fade, whether up or down:
0 — Fade up
1 — Fade down and set GPI2
GPI2 is an internal signal on the Vela media bus used to signal the secondary
decoder when the Fade Down is complete, so that the secondary can begin the
Fade Up operation.
Secondary Decoder
Determines which decoder is the Primary Decoder (decoder which audio/video
output is being monitored):
1 — Secondary decoder
0 — Primary decoder (this is the one whose output is monitored
where video/audio switching occurs)
One decoder must be set to be Primary and the other decoder must be set to be
Secondary.

2. Issue a Fade Down to Channel 0, usually sent inline to execute on a Frame
Count (inline mode 3) or GOP TimeCode (inline mode 1). The fade down will
start executing when the trigger frame/TimeCode occurs. When the fade down
completes, the primary channel will set GPI2 signal the secondary decoder to
begin the fade up. Also when the fade down is complete, the Audio/Video
Mux hardware will select Channel 1 (secondary) audio and video sources.

MODE SENSE (6)
(OpCode 0x1A, 6 bytes)
The MODE SENSE command allows the initiator to read the mode pages. This is the
complementary command to
Table 2-14.MODE SENSE Command Format
MODE SELECT.
DBD – Disable Block Descriptor
When DBD = 0, the decoder returns the Block Descriptor. If DBD = 1, the decoder
does not return the Block Descriptor.
Page Code
Determines which pages are returned to the initiator. Page Code of 3Fh causes all
supported pages to be returned. See
MODE SELECT for description of Mode Page
Header, Block Descriptor and changeable page formats.
Page Control (PC)
This field defines the type of mode parameter values to be returned by the
SENSE command.

Current Values: The decoder will return the current values of the request mode
page.
MODE SENSE (6)
Page 96

Changeable Values: The decoder returns a mask denoting those mode parame-
ters that can be changed by a
MODE SELECT command. In the returned mask, the
fields of the mode parameters that are changeable are set to a 1 and those that
are non-changeable are set to a 0.
Default Values: The decoder will return the default values of the request mode
page.
Saved Values: The decoder will return the values which are saved in non-volatile
memory. The firmware maintains a place holder for Saved Pages, but since nonvolatile page save is not currently supported, the Saved Values are the same as
the default values.

Table 2-18.Vela MPEG Decoder Status Page Format
GPIN1
Returns the state of the general purpose input discrete 1 (GPIN1):
0 = Input shorted to ground (closed or low)
1 = Input open (high)
GPIN2
Returns the state of the general purpose input discrete 2 (GPIN2):
0 = Input shorted to ground (closed or low)
MODE SENSE (6)
Page 99
Chapter 2 — Decoder Command Set Guide 89
1 = Input open (high)
Note that GPIN2 is dedicated to audio/video switching and fading.
Vela Media Bus Direction
When performing audio/video switching and fading, two CineCast HD decoders
are connected together through a ribbon cable, called the Vela Media Bus. One
card is configured to output video and audio data onto the Media Bus; the second
card is configured as an input.
0b — Vela Media Bus is an input.
1b — Vela Media Bus is an output.
Video Source Select
Determines whether video source comes from this card’s video decoder or from
the other card across the Vela Media Bus.
0b — Video source from this decoder (Primary).
1b — Video source from other HD decoder across the
Vela Media Bus (Adjacent).
Genlock Valid
Returns state of genlock source and Video Switch status. Bit 4 reflects the status
of the video switch; bit 3 reflects the status of the genlock input source.
0b — Genlock loss or standalone mode (non-genlock).
1b — Genlock is valid.
Under
Set to 1 when decoder enters a pause on data underflow condition. See
PLAY (A5h), Error Recovery on Data Underflow (ErrRcvy).
MPEG
Queue
Set after a
RESET BUFFER is received; cleared only after playback has started.
Play
Set to 1 when playback is active; 0 indicates decoder is idle.
Unused FIFO Data After Stop
Reports the number of 64-K blocks of MPEG data unused after a Stop has been
issued.
Last Decoder Command
Indicates the last command code executed by the decoder firmware. See Opcode
DECODER command for command codes.

Frame Reporting
Returns the current frame number (number of video frames decoded). Starts at
0 and increments for each picture decoded. This frame count accounts for all
trick modes (Pause, Slow Motion, Fast Forward, and Frame Advance). Mode
Page 34h provides a frame number, which is derived from the GOP time code.
Data Underflow Error Count
Returns the number of data underflows since power-up/reset. The count is incremented on a data underflow when ErrRcvy = 1 in the
MPEG PLAY (A5h) command.
FIFO Buffer Status
Returns the number of 64-K buffers free on the decoder. The number of buffers is
defined as twenty-four 64K buffers, 1.5MB.
GPOUT1
Returns the state of the general purpose output discrete 1 (GPOUT1):
0 = Output active (closed or low)
1 = Output open (high)
GPOUT2
Returns the state of the general purpose output discrete 2 (GPOUT2):
0 = Output active (closed or low)
1 = Output open (high)
Note that GPOUT2 is dedicated to audio/video switching and fading.
Preload
Indicates that the decoder is loading data into the MPEG hardware but playback
has not begun. After the decoder channel has received the MPEG Play command,
the decoder normally takes some amount of time to preload MPEG data before
audio and video is generated.
During a “Pause on First Frame,” the Play bit (byte 2 bit 0) does not get set until
Resume occurs. The Preload bit will remain set while the decoder is paused on the
first frame. Preload is cleared when playback starts, i.e., when the Play bit is set.
Pause
Set when the decoder enters the paused state. When using “Pause on First
Frame,” this bit gets set when the paused frame is reached. The bit is cleared
when playback is resumed.
