Controlling multiple data transmission connections and providing a method for selecting a delivery mechanism based on RTP

On the customer side, the data is transferred using the "pull mode". The RTP/RTCP filter continuously accepts RTP messages from the network and passes them to the asynchronous source filter, which transfers the media data all the way down in the pull mode, is decoded during the transfer process, and is finally played back. Two buffer pools are used. These two buffer pools play a key role in ensuring smooth and uniform transmission and reception of media data streams, which can greatly reduce the loss rate of network transmission data packets and effectively improve the transmission quality of the media.

There are five types of RTCP control packets, of which two are used to provide QSo feedback: sender report (SR) and receiver report (erecviererport, RR). The former describes the transmission and reception statistics of the sender; the latter describes the reception statistics of the receiver. These statistics include the number of transmitted packets, the number of transmitted bytes, the total number of lost packets, the maximum sequence number of received messages, and the jitter of the arrival interval. In short, RTP is a data transfer protocol, and RTCP is a control protocol.

RTSP Protocol Real Time Streaming Protocol (RTsp) is an application-level protocol that controls the transmission of real-time data. Provides an extensible framework that enables controlled, on-demand playback of real-time data such as audio and video. The purpose of the protocol is to control multiple data transmission connections, provide a path for selecting transmission channels (such as UDP, multicast UDP, and TCP), and provide a method for selecting a transmission mechanism based on RTP.
