Based On Ts Stream Cable Transmission Of Mpeg <sub> 2 </ Sub>

This paper mainly focuses on the research on how to transmit the MPEG-2 TS by cable communication network. It first introduces the MPEG-2 standard and the grammar structure of the TS. Then it describes the principle of synchronization and multiplexing in digital communication . The synchronization comprises the carrier synchronization, bit synchronization, group synchronization and network synchronization while the multiplexing includes bit multiplexing, word multiplexing and frame multiplexing. Then, two approaches of how to transmit MPEG₂ TS are introduced-transmission using the inverse multiplexing technology through the interface of E1 telecommunication and fiber transmission. As for the inverse multiplexing, its principle and some multiplexing types are introduced. Then, a disassembly program is designed using the FPGA. It divides one MPEG₂ TS whose data rate is 4.096Mbps into two E1 data streams whose data rate are 2.048Mbps. A re-assembly program is also designed which assembles two data streams at 2.048Mbps into one data stream at 4.096Mbps. Both of the programs are simulated on computer. As for the fiber transmission, this paper introduces two ways of fibre transmission which are serial transmission and parallel transmission. The problems met in the hardware debug of fibre transmission are also analyzed. Such work are done by the author:1. consulting the reference books , getting the basic knowledge of inverse multiplexing and fiber transmission .2. accomplishing the design which transmits MPEG₂ TS through the E1 telecommunication interface with the inverse multiplexing technology; completing the inverse multiplexing program using FPGA and simulating it. 3. completing the circuit design based on the serial fiber transmission and the parallel fiber transmission and theirs hardware debug.4．completing the joint-debug on the system which is made up of the serial transmission system or the parallel transmission system with the MPEG-2 multiplexing/de-multiplexing equipments.
