iRTSP Message

An iRTSP message is composed as follows:

Version + CRLF
"Seq" + = + Sequence Number + CRLF
Type + / + Method (+ / + Code) + CRLF
Header (+ = + Value) + CRLF
...
"Submit" + CRLF

All iRTSP messages end with the word Submit, followed by a CRLF.

Example iRTSP request:

iRTSP/1.21
Seq=0
SET/START
t=45850
sc
Submit

Example iRTSP response:

iRTSP/1.21
Seq=0
RSP/START/200
t=45850,1806955874,1806955874
sc=tls
Submit

Version

This represents the iRTSP version used. Example: iRTSP/1.21

Sequence Number

This stores the sequence value of an iRTSP message. It works the same way as the CSeq header of a standard RTSP message.

Message Type

This differentiates if an iRTSP message is a request or a response. If the message is a request, it will have the value SET. If the message is a response, then it will use the value RSP. Both the client and server can send request and response messages.

Method

This stores the method used on the message. The known possible values are:

• START
• SETUP
• KNOCK
• PUSHINFO
• USERINFO
• REMOTECTL
• SET
• PLAY
• ECHO
• TEARDOWN

Headers

All message headers have a header field and value. These are split with an equal sign = and with no spaces, instead of the usual two dots : used in standard RTSP.
