| Abstract: | CATV STB is not only an end-platform of digital television and integrated services based on CATV, but also the most significant gangplank of holistie shifting to digital television. The building block of it is the digital television decoder core, which decodes the video and audio signal. This paper analyzed the framework, function and system data stream of DTDC, especially studied the accomplishment of video decoding and presented the specific fabric and lively function of it. Finally, it summarized the realization of digital audio, presented the framework of STB and the effect of decoding. |
