| Abstract: | This paper introduced the transmission of MPEG-2 transport stream in the modulator of ATSC, and mostly discussed how to receive TS data from the asynchronous serial interface (ASI). Then the difference rates of TS from MPEG-2 encoder and ATSC modulator are illustrated in detail. So an efficient way of inserting null packets is applied to the modulator. Finally the experimental results on hardware are presented, which confirm its correctness and strong reliability. |
