Description
Zoran's SupraHD-680 ATSC/NTSC and Unidirectional OpenCable
(UDC) reference design is a complete hardware and software
solution for building an integrated Digital Cable Ready (DCR) Digital
Television (DTV) targeted at the United States market. The reference
hardware module can be implemented in an LCD-based or
CRT-based DTV. The reference TV application software complies
with the ATSC and OpenCable broadcast standards.
The reference design is a full-featured system that allows tuning,
decoding, and display of analog (NTSC) and digital (ATSC) terrestrial
broadcast, and cable transmission.The SupraHD-680 DTV System IC
decodes standard-definition and high-definition content. This IC is
highly integrated, consisting of a MPEG-2 decoder, NTSC video
decoder, HDMI interface, IEEE-1394 interface, CableCARD interface,
high-performance CPU, powerful graphics engine, video scalar, video
enhancement, LVDS driver and various peripherals necessary for
building an integrated DTV. The reference hardware module accepts
the traditional video equipment interfaces, such as composite
(CVBS), S-video (Y/C), and component (YPbPr) inputs, as well as
the more advanced interfaces, such as HDMI from newer DVD
players and IEEE-1394 from digital video recorders. It also accepts
VGA input from a personal computer. For the output interfaces, the
reference hardware module can directly drive an LCD panel or a
CRT TV. Other outputs are L/R audio for its internal speakers and
SPDIF for multi-channel output to an external audio receiver.
The reference TV application supports the basic functionalities
required for a DTV, such as an ATSC/NTSC software stack,
Electronic Program Guide (EPG), closed-caption decoding, parental
control, basic audio control (i.e. bass, treble, balance), and basic
video control (i.e. contrast, brightness, color). In addition, the
CableCARD software stack is provided, thereby meeting the FCC
mandate of requiring DTVs to be digital cable ready. For ease of
connectivity to external devices, such as digital video recorders, the
IEEE-1394 software stack is also bundled with the software package.
