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.

Introduction
2CineCast 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.

Decoder Installation
Chapter 1 — Getting Started11
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
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
12CineCast 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.
Depending on the cable purchased, signals appearing on the cable can include
YUV, RGB and composite video, LTC time code, AES audio, analog audio, GPI
in and out, and VGA monitor signals.
The input end of the cable assembly terminates in a connector that mates with the
Microcross P&D connector located on the CineCast HD decoder board.
Table 1-4 and Table 1-5 contain pinout information for the available pre-fabricated cable assemblies. Vela part numbers are 6000-0165 (YUV and balanced
audio) and 6000-0166 (RGB and balanced audio). Contact your Vela sales representative to order the cable assemblies.
