本文提出了一种基于流媒体Location Free电视的解决方案, 既可以实现一般的电视收看功能,而且直接通过内置的视频网络传输模块连接在异地的电视机,收看在异地的电视频道。在解决方案中,视频采用了目前压缩率最高的H.264编解码算法,音频采用目前使用最广的G.711的编解码算法,并使用网络的流媒体传输协议,进行实时处理,从而实现异地电视信号实时传输通信。

This paper presents a Location Free TV solution based on streaming media. Through this solution, we can not only maintain the general television viewing features, but also watch the television channels at a different location through the builtin video network transmission module which connects the television in different locations.In this solution, we use the H.264 codec algorithm for video compression and the G.711 codec algorithm for audio compression, and also use the Internet Streaming Media Transfer Protocol, so as to conduct realtime processing, thus achieve a realtime remote television signal transmission.
