There are a number of general topics we should list here and link to. To get things rolling:
- Protocol to describe, setup, play, and tear down (RTP) streams
- Usually on port 554
- Client can request in the setup the port range to transfer RTP back to the client ** per spec it should be a sequential range starting from an even number e.g. 9010-9011
- TCP
- The protocol to move the data from RTSP handshake.
- Usually UDP, but can be TCP
- Protocol to send stream reports between the server and client and vice versa
- Client sends statistic reports about the reliability of the udp stream
- Client sends reports to keep the stream alive from the server
