Design And Implementation Of MPEG-2TS Monitor Sistem

With the development of technology and the establishment of network, the growingdemand for high-quality video and audio programs, Digital TV is an inevitable process toachieve this requirement. A global digital TV revolution has begun, in the emerginghigh-tech field, Digital TV technology has become one of the most promising hot spot.Digital TV favored consumers greatly with vast market and enormous economic benefits,and popularized rapidly. For security of the digital signal’s quality,the system mustmonitor the digital TV signal’s process,and inform the workers of the monitoring resultstimely and accurately, that make workers can correct troubleshooting quickly.So,MPEG-2TS monitoring system be born at the proper time and conditions.The design and implementation of MPEG-2TS moitoring system has greatsignificance of the research. First, we must understand the Digital TV system and theDigital TV stream monitoring system.Second, we must be familiar with the protocols andstandards of the digital stream and Digital Video Broadcasting. Especially,the specificdefinition and information of the PSI in the MPEG-2’s TS stream,with content of TR101290standard.At this time, we can carry on the demanded analysis of the MPEG-2TSmonitoring system and summarize all kinds of function that MPEG-2TS moitoring systemshould have. Then we get the whole design scheme, basing on the demandedanalysis.Finally,in order to make the system has good scalability,designing with the objectoriented of developed method and the idea of module in detail.MPEG-2TS monitoring system be researched and developed under Windows andVisual C++, which can help the Digital TV operators to diagnosing the problems andfounding the fault signal timely and easily. In order to improve the use of hardwareresources efficiently,using multi threading technology to write software. Throughmonitoring digital signal in the Digital TV front, can take corresponding measures at realtime and improve the quality of service greatly, which play a decisive role in the customersatisfaction of Divital TV operators.
