Abstract


With the rapid development of digital TV technology , MPEG-2 compression coding standard universal standards in the field of digital television applications , especially suitable for the encoding and transmission of digital TV broadcast , digital television broadcasting , the diversification of the program , the increasing demand for high quality audiovisual information , the information from the network , interactive increasingly urgent, in this case, the multiplexing of the program is becoming increasingly important . Based on the development of the MPEG-2 compression coding standard multiplexing , brings the possibility for the effective utilization of the channel bandwidth . The MPEG-2 standard is an open , standards development , research is still in the process of practice development , improve . MPEG standard , for a long period of time , it will build the system on the basis of digital audio and video . This article focuses on the MPEG - 2 multiplexing and demultiplexing . First, the specification of the MPEG-2 standard system layer , in - depth learning MPEG-2 based on the relevant theoretical knowledge reuse , focused on solving a single multiplexed transport stream synchronized audio and video sync issues . The proposed use of the relationship between the program clock reference and a decoding time stamp to determine the order of multiplexing algorithm . For multiplexing the demultiplexed also study and A Solution multiplexed programs . Research , this article provides a set of the transport stream multiplexing and demultiplexing software implementation program , and developed software based on the Windows environment . But profound connotation of MPEG-2 standard , there is no specific provision for multiplexing and demultiplexing , there are a lot of follow-up work can continue , such as multi-channel program multiplexing , multiplexing demultiplexing hardware and software combination .
