Which protocol is used for media transport?

Explanation:
Media transport for real-time audio and video relies on a protocol built to carry time-sensitive payloads with accurate timing and sequencing. The Real-time Transport Protocol provides the mechanism to carry the media stream itself, including timestamps for synchronization, sequence numbers for ordering, and payload type identifiers. It’s designed to minimize delay, typically running over UDP to keep latency low, which is essential for live communications. In many setups, RTP works alongside RTCP, which provides quality monitoring and compensates for jitter and packet loss. The other protocols serve different roles. RTSP is used to control streaming sessions—things like starting, stopping, and seeking through a media stream—while RTP handles the actual transport of the media data. SIP is a signaling protocol used to establish, modify, and terminate multimedia sessions, not to carry the media itself. HTTP is the web protocol used for request/response interactions and is not optimized for real-time media delivery. That's why RTP is the correct choice for media transport.
