The Real Time Streaming Protocol (RTSP) is a network control protocol designed for use in Multimedia Session Control Working Group (MMUSIC WG) of the Internet Engineering Task Force (IETF) and published as RFC in RFC Real Time Streaming Protocol (RTSP) (Q). request for comments publication.

If a 2236 extension requires that intermediate devices support it, the extension should be tagged in the Proxy-Require field instead see Section Implementation of scale changes depends on the server and media type. If the request contains a Range parameter, the new scale value will take effect at that time. If the request contains a Range parameter, the new speed value will take effect at that time. If the source address for the stream is different than can be derived from the RTSP endpoint address the server in playback or the client in recordingthe source MAY be specified.

Any retransmitted request must contain the same sequence number as the original i. For audio, it may time-scale the audio while preserving pitch or, less desirably, deliver fragments of audio. Indicates that the client is willing to accept a media stream that has exceeded its expiration time. Below are the configuration parameters associated with transport: The block size MUST be a positive decimal number, measured in octets. The range can be specified in a number of units. Within RTSP, redirection may be used for load balancing or redirecting stream requests to a server topologically closer to the client.
ABNF for SDP – Session Description Protocol
The following examples are not to be used as a reference for those formats. In this example, the client is only interested in the last 226 of the movie. Pages using RFC magic links Articles needing additional references from September All articles 226 additional references Articles lacking in-text citations from July All articles lacking in-text citations Articles with multiple maintenance issues.
The relationship between “funky-feature” and Funky-Parameter is not communicated via the RTSP exchange, since that relationship is an immutable property of “funky-feature” and thus should not be transmitted with every exchange. This page was last edited on 4 Juneat Thus, it does not introduce additional latency. This keeps the syntax of the Transport header simple and allows easy parsing of transport 23326 by firewalls. The movie is stored in a container file.
The address to which a stream will be sent. Retrieved from ” https: Just as an HTTP cache has to store the content type, content language, and so on for the rf it caches, a media cache has to store the presentation description. Views Read Edit View history.
Note that the language specified applies to the presentation description rdc any reason phrases, not the media content. It may also give an indication about the timeline of the movie.
SDP attributes defined in RFC (RTSP )
It also allows treating all the streams equally in case of any prioritization of streams by the server. In that case, the server MUST return a single option which was actually chosen. This error will most likely be the result of a client attempt to place an rfx Destination parameter in the Transport field.
Clients of media servers issue VCR -style commands, such as playrecord and pauseto 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.
The parameter value is expressed as a decimal ratio, e. A Transport request header field may contain a list of transport options acceptable to the client.
The Transport header MAY also be used to change certain transport parameters.
Ranges are half-open intervals, including the lower point, but excluding the upper point. If the 2362 parameter includes RECORD, the append parameter indicates that the media data should append to the existing resource rather than overwrite it. A server SHOULD not allow a client to direct media streams to an address that differs from the address commands are coming from.

In other words, a ratio of 2 has normal play time increase at twice the wallclock rate. For aggregate control, a particular stream may not actually generate a packet for the Range time value returned or implied.
