| Abstract: | System-level multiplexing principle of TS(Transport Stream)in DVB(Digital Video Broadcasting) system is analyzed. The key technologies of retrieval and reorganization for program specific information and regulation for program clock reference value in system layer are discussed in detail. And then, a software system is designed and implemented to analyze and multiplex the TS. The testing results show that the software multiplexing rate is greatly faster than a single TS speed and the proposed software schem... |
