SupraHD 775

ATSC/NTSC DTV Module Reference Design

Overview

Overview

Zoran’s SupraHD® 775’s reference hardware module can be used in a LCD-based DTV. The reference TV application software complies with the ATSC broadcast standards.

The reference hardware module accepts the traditional video equipment interfaces including four (4) composite (CVBS), three (3) S-video (Y/C), and dual component video (YPbPr) inputs, as well as three (3) HDMI v.1.3 with deep color. It also accepts VGA input from a personal computer, as well as 6 pairs of analog audio inputs.

For the output interfaces, the reference hardware module can directly drive a LCD panel up to 10 bit color. Other outputs are L/R audio for its internal speakers and SPDIF for multi-channel output to an external audio receiver. This chip is highly integrated, consisting of a MPEG-2 decoder, 8VSB/QAM demodulator, two (2) HD analog video inputs, NTSC video decoder, triple HDMI 1.3 interface with deep color, high performance CPU, powerful graphics engine, video scaler, video enhancement, dual LVDS driver and various other peripherals necessary for building an integrated DTV.

The reference TV application supports all 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 and sharpness).

The reference design supports 720P display via LVDS output to FPD.
