Implementation method of VCR function in VoD based on transport stream
.一种基于传输流的视频点播VCR功能实现方法*

As an efficient multimedia transport and storage format, TS(transport stream) is widely used in various network VoD systems. However, the inhere format of TS designed for broadcasting application can not provide adequate support for flexible man-machine function (VCR function). Based on the characteristic of TS format,the paper designed a fast localization method according to the time ,and then put forward an efficient data selecting scheme used in fast/back forward to support VCR function of TS and the realization of man-machine function in VoD based on transport stream.
