Abstract

This invention relates to a media server and method for realizing media route thereof, which contains coding unit, decoding unit, code stream conversion unit, main control unit, network management control unit, IP network unit, hard disc storage unit, DVD-ROM driving unit, DVD-S / DVB-C / DVB-T receiving unit, and multicomplexing unit, which features 1, converting various audio-video data stored in different medium into TS stream adapted to digital television broadcast, then outputting through ASI or IP network, to effectively utilize various kind of media data and realize digital broadcast in minimum image loss, 2, converting the real time program received by DVD-S / DVB-C / DVB-T receiving unit through media route, playing more than two times program in one channel after multiplexing.

Description

technical field [0001] The present invention relates to a digital TV broadcasting front-end broadcasting device and a construction method thereof, in particular to a media server for providing streaming media in the front-end broadcasting device and a construction method and a media routing method thereof. Background technique [0002] Channel resources are scarce resources for TV broadcasting, so how to use limited channel resources to transmit more programs has always been the goal pursued by the broadcasting industry. Each channel can only transmit 6 sets of video programs. If it is broadcast on the IP network, even if a set of MPEG2 video programs are transmitted, it is impossible to play them in real time. Although the existing image compression technology has been greatly improved, such as MPEG4, it can save 50% of the bandwidth compared with MPEG2 under the same image quality. If the H264 compression standard is used compared with the MPEG2 standard, the compression ...
