Description

The VideoDecoder 4 MOST is a complementary device for testing MOST video sources within a MOST system. The functionality of such Devices Under Test (DUT) can be easily very-fied through outputting the MPEG Transport Stream via the VideoDecoder 4 MOST to a standard monitoring device.

MPEG2 Transport Stream data packets are transmitted over the MOST network via synchronous channels as continuously streamed data bytes. A multimedia processor OS8805 receives this broadcasted audio/video content and rebuilds the MPEG2 packets out of the synchronous data stream. These packets are passed for further processing to the MPEG Decoder, which produces an analog stereo audio signal, a S-Video (Y/C) and a composite video (CVBS) signal. The output signals can be connected to various standard monitoring devices.
