摘要
在介绍AVS标准的系统部分的基础上,阐述了与MPEG-2标准系统部分的联系与区别。给出了一种易于实现的以帧为单位打PES分组包的复用方法,实现了完全符合AVS标准的传输流和节目流的复用。并且,利用AVS系统部分与MPEG-2系统部分的高度兼容性,给出了一种成本极其低廉的实现AVS音视频数据流复用解复用的方法。该方法完全不需要研制AVS复用解复用设备,而是利用现有的MPEG-2复用解复用设备就实现了AVS标准的传输流和节目流的复用。
In this paper, based on the introduction of the system of AVS standard, the relation and difference between the system of AVS standard and that of MPEG-2 standard is discussed. Then, an easy-to-realize scheme of AVS system multiplexer is proposed, in which one frame is packed into one PES packet, and by which, the Program Stream and the Transport Stream that are fully in compliance with the AVS standard can be obtained. In addition, using the high compatibility between the AVS and MPEG-2 systems, a very low cost scheme of AVS audio/video multiplexer/demultiplexer is proposed in which no muhiplexer/demultiplexer specially developed for AVS is needed, but the existing MPEG-2 muhiplexer/demultiplexer can be used to do the work instead.
