● Network control protocol designed for use in entertainment and communications systems to control streaming
media servers.
● The protocol is used for establishing and controlling media sessions between end points. Clients of media servers
issue VHS-style commands, such as play, record and pause, to facilitate real-time control of the media streaming
from the server to a client (Video On Demand) or from a client to the server (Voice Recording).
● RTSP defines control sequences useful in controlling multimedia playback. While HTTP is stateless, RTSP has state.
An identifier is used when needed to track concurrent sessions. Like HTTP, RTSP uses TCP to maintain an end-to-
end connection and, while most RTSP control messages are sent by the client to the server, some commands travel
in the other direction.
7. SRT – Secure Reliable Transport
•
EXTREMELY SECURE: Using the same 128/256 bit AES encryption trusted by governments and organizations
around the world, SRT ensures that valuable content is protected end-to-end from contribution to distribution so
that no unauthorized parties can listen.
•
ALWAYS RELIABLE: No matter how unreliable your network, SRT can recover from severe packet loss and jitter,
ensuring the integrity and quality of your video streams.
•
LOW LATENCY ERROR RECOVERY: SRT’s stream error correction is configurable to accommodate a user’s
deployment conditions. Leveraging real-time IP communications development to extend traditional network error
recovery practices, SRT delivers media with significantly lower latency than TCP/IP, while offering the speed of
unreliable UDP transmission without the disadvantages.
•
EASY FIREWALL TRAVERSAL: The handshaking process used by SRT supports outbound connections without the
potential risks and dangers of permanent exterior ports being opened in a firewall, thereby maintaining corporate
LAN security policies and minimizing the need for IT intervention.
•
CONTENT AGNOSTIC: Unlike some other streaming protocols that only support specific video and audio formats,
SRT is payload agnostic. Because SRT operates at the network transport level, acting as a wrapper around your
content, it can transport any type of video format, codec, resolution, or frame rate.
