Common Application layer protocol HTTP, RTSP, rtmp comparison

HTTP (Hypertext Transfer Protocol), RTSP (Real time Streaming protocol live streaming protocol), RTMP (Routing Table Maintenance Protocol Routing Tables Maintenance Protocol) is the application layer protocol, Theoretically all can do live, on-demand, in fact, live more than rtmp and RTSP, on-demand is more use RTSP and HTTP.

First, common areas:

HTTP (HTTPS) all data as text processing, widely used in network access, is a public agreement, with specialized agencies to maintain. RTSP Streaming protocol, multi-use in the field of surveillance video broadcast on-demand, is a public agreement, with specialized agencies to maintain. RTMP Streaming protocol, used in the Internet Live Broadcast (RTMP+CDN), video conferencing (instead of the original sip), is Adobe's private agreement, not fully disclosed. RTSP transmission generally requires 2-3 channels, command and Data channel separation, HTTP and rtmp generally on a TCP channel to transmit commands and data. The RTMP protocol generally transmits the FLV,F4V format stream, and the RTSP protocol generally transmits the stream in the Ts,mp4 format. HTTP does not have a specific stream.
