SupraHD 741
ATSC Converter Box
Overview
Overview
Zoran’s SupraHD® 741 reference design consists of a set-top-box ready for manufacturing and a set-top-box application with complete middleware software stack, including closed-caption support. The set-top-box accepts all the ATSC formats (480i, 480p, 720p, 1080i) and outputs 480i to a NTSC TV.The SupraHD® 741 Processor is highly integrated, consisting of an 8VSB demodulator, an MPEG-2 HD decoder, high-performance CPU, graphics engine, video scaler, channel 3 / 4 modulator, stereo audio DAC and integrated sleep mode support without a microcontroller.
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 composite (CVBS), and S-video (Y/C, optional) and channel 3 / 4 RF modulated formats.
Audio can be output in analog format (L/R). Designed to use the minimum external components, the SupraHD® 741 Processor requires only memory, ATSC tuner, power supply, and a small number of passive components to build a complete ATSC converter box.
