| Abstract: | For the international mainstream solutions for digital television source decoders, special-purpose chips, lacking of extensive adaptability and flexibility in functional change, the overall scheme and hardware implementation of the standard definition digital television source decoder based on the general digital signal processor (DSP) , TMS320C6415, are put forward. The scheme can demultiplex transport stream and decode audio and video by software in real-time. The system runs stably, and the output of audio and video is of high quality. |
