| Abstract: | The paper describes a system for converting the MPEG-2 program streams to the transport streams in order to provide more programs for the digital TV service. The paper covers three main (areas): first, the structure of MPEG-2 program stream and transport stream; second, detailed implementation of the conversion system; and third, key techniques and related components of the system. The results of real-time play and off-line analysis indicate that the system can convert the MPEG-2 program stream to the transport stream correctly and steadily. |
