For example, RTSP (real-time Streaming protocol) it contains both the RTP,RTCP and the RTSP protocol inside. However, in some systems with very few system resources, the independent use of RTP protocol becomes more and more important. The RTP protocol is generally not very complex, but if each

not competitive, so the customer has a rolling channel, that is: the On-Demand files are arranged to form a series of content and an EPG, and then broadcast through the software + device. What the customer sees is the continuous broadcast content. (The rolling Broadcast Channel has a lot of news, sports, music, and so on.) We developed the rolling broadcast and editing single system.
