What crucial timing information does RTP incorporate for media packet delivery?
Sequence numbers and timestamps.
The Real-time Transport Protocol (RTP) is the mechanism specifically designed to carry the actual time-sensitive media data packets over the network. To ensure that the receiving client can reconstruct the audio or video stream correctly, RTP must compensate for potential network jitter and delays, ensuring smooth playback. It achieves this by embedding essential metadata directly onto the packets. This metadata includes sequence numbers, which allow the client to reorder packets that may arrive out of sequence, and timestamps, which are vital for maintaining the correct playback timing relative to the source. Without these elements, continuous, synchronized media presentation would be impossible, regardless of how the control commands are issued.
