Description
Zoran's SupraHD-640 ATSC reference design is a complete
hardware and software solution for building a low-cost ATSC DTV
Module that upgrades an existing NTSC Television to be ATSC
compliant. The reference design consists of a hardware module ready
for manufacturing and a TV application with complete
middleware software stack, including closed-caption support. The
hardware module accepts all the ATSC formats (480i, 480p, 720p,
1080i) and outputs 480i to a NTSC TV.
The SupraHD-640 DTV System IC is highly integrated, consisting of
an MPEG-2 HD decoder, high-performance CPU, power graphics
engine and video scaler. It also supports a variety of system
interfaces, such as an infrared receiver, flash memory and DDR
SDRAM interfaces. The decoded ATSC video stream can be output in
component (YPbPr), composite (CVBS), and S-video (Y/C) formats.
Audio can be output via an SPDIF interface or in analog format (L/R)
using the chip's integrated audio DAC. Designed to use the minimum
external components, the SupraHD-640 requires only memory, ATSC
demodulator, ATSC tuner, and a small number of passive
components to build a complete ATSC DTV Module.
