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-of-
information 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.
