| Abstract: | The design and implementation of live broadcast system based on DVB is proposed in this paper. The delay is implemented through video server. This system supports multiple-channel live broadcast at the same time, through the software method of extracting single program transport streams from multiplex-program transport streams. This system can be integrated with the hard disk broadcast system. The transport streams are measured according to the measurement guidelines, and the result is discussed in this paper. |

| Keywords: | DVB video server delay live multiple-channel transport stream software de-multiplex |
