Based On Mpeg-2 Transport Stream In The Dvb System Software To Achieve Multi-program Reuse

With the development of multimedia technology, digital video communication has become the trend of development. As ISO/IEC defined MPEG-2 International Standard, many kinds of production show up in the multimedia market. The most representative phenomenon is the rapid development of Digital TV. And the following foundation of DVB standard which based on the MPEG2 Transfer Stream framework and its swift popularization deeply accelerate the application of the digital video communication.The Transport Stream is a stream definition which is tailored for communicating or storing one or more programs of coded data according to MPEG-2 standard in environments in which significant errors may accur. Such errors may be manifested as bit value error or loss of packets.It is possible to construct Transport Stream containing one or more programs from elementary coded data streams. From Program Streams, or from other Transport Streams which may themselves contain one or more programs.The author makes a deep research to the MPEG-2 Standard in this paper. Based on this work, we bring forword the construct of multiplex program through the requirement in the application. In the mean time, we consider not only the modulization of our program, but also the inheritance and maintenance properties of the source code.In chapter 1, this paper introduces the DVB Standard. Chapter 2 introduces the MPEG-2 International Standard. Chapter 3 introduces the definition of Transport Stream. Chapter 4 introduces the realize of the Multiplexing System. Chapter 5 introduces the main blocks of the program. The last chapter gives a testing result of this system.
