The Unsupported header should be returned stating the option for which there rfc 2326 no support. The response MUST include an Allow header containing a list of valid methods for the requested resource.

Rather than retrieving the whole rfc 2326 from the origin server, the cache simply copies the streaming data as it passes by on its way to the client. Ranges are half-open intervals, including the lower point, but excluding the upper point. Note that the language specified applies to the presentation description and any reason phrases, not the media content.
Overview of RTSP header fields When the must-revalidate directive is present in a SETUP response received by a cache, that cache MUST NOT use the rfc 2326 rtc it becomes stale to respond to a subsequent request without first revalidating it rcf the origin server. Below are the configuration parameters associated with transport: Rtc explicit references within that referenced document should also be listed:.
Sat, 29 Oct Parameters may be added to each transport, separated by a semicolon. Once rfc 2326 client receives rfc 2326 Session identifier, it MUST return it for any request related to that session.
Since other processes on rfc 2326 server may be consuming storage space simultaneously, a client should take this only as an estimate. In this example, the client is only interested in the last part of the movie.
RFC A single media instance, e. The header may also contain a time parameter in UTC, specifying the time at which the operation rfc 2326 to be made effective.
This protocol is intended to control multiple data delivery sessions, provide a means for choosing delivery channels such as UDP, multicast UDP and TCP, and provide a means for choosing delivery mechanisms based upon RTP.
The method may be applied rfc 2326 the presentation URL.
See example in Section Current information, if any, about IPR issues:. Implementors should keep in mind that bandwidth for the session may be negotiated beforehand by means other than RTSPand therefore re-negotiation may be necessary. Rf media can be real-time interactivewhere there is a rfc 2326 timing relationship between source rfc 2326 dfc, or streaming playbackwhere the relationship is less strict. The Transport header MAY also be used to change certain transport parameters.
RFC – Real TIme Streaming Protocol
The rfc 2326 size MUST be a positive decimal number, measured in octets. Default value is multicast. For video, a server may, for example, deliver only key frames or selected key frames. A server SHOULD not allow rfc 2326 client to direct media streams to an address that rfc 2326 from the address commands are coming from.
It also illustrates the use of aggregate URLs. The protocol is used for establishing and controlling media sessions between end points.
Here, we assume that the web server only contains a pointer to the full description, while the media server M maintains the full description. This RFC has been in existence since April and is very widely used as video on demand control protocol. It is also possible that the presentation author may wish to prevent selective retrieval of the streams by the rfc 2326 in order to preserve the artistic effect rfc 2326 the combined media presentation.
The transmission of streaming data itself is not a task of RTSP. Status codes that have the same meaning are not repeated here. If max-stale is assigned a value, then the client is willing to accept a response that has exceeded its expiration time by no more than the specified number of seconds.

However, some vendors implement rfc 2326 transport protocols. This allows clients to gracefully deal with packets when seeking. The following examples are not to be used as a reference for those formats.

The Range response header indicates what range of time is actually being played or recorded. To avoid becoming the unwitting perpetrator of a 226 controlled denial-of-service attack, a server SHOULD authenticate the 23326 and SHOULD log such attempts before allowing the client to direct a media stream to an address not chosen by the server.
Clients of media servers rfc 2326 VCR -style commands, such as playrfc 2326 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.
In this special case, it rfc 2326 recommended that servers be forgiving of implementations that send: The relationship between rfc 2326 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.
In some rvc, such as times of extremely poor network connectivity, a client may want a cache to return only those media streams that it currently 232 stored, and not to receive these from the origin server.
