Abstract
The invention provides a video on-wall configuration method for an analog TV wall. The method comprises the following steps that a client sends a video on-wall command to a command processing server, and the command processing server forwards the video on-wall command to a video and audio controller; the video and audio controller receives the video on-wall command, forwards a video and audio on-wall command to an Rtsp (real time streaming protocol) server, and also requests a streaming media server to provide a video and audio on demand service; the streaming media server receives the request and then sends a high-bit-rate video and audio stream to the Rtsp server, and then the Rtsp server sends the high-bit-rate video and audio stream with an Rtsp protocol and a control stream to a data matrix or decoder, and the high-bit-rate video and audio stream and the control stream are displayed on a TV wall screen after being processed by the data matrix or decoder; meanwhile, the streaming media server converts the high-bit-rate video and audio stream into a low-bit-rate video and audio stream and sends to the client, and the client displays an image. The invention also provides a video on-wall configuration system for the analog TV wall. The client operation is facilitated and the working efficiency of the client is improved.
