However, it is desirable for the continuous media data, typically delivered out-of-band with respect to RTSP, to be cached, as well as the session description. A server does not have to set up a session identifier if it has other means of identifying a session, such rff dynamically generated URLs.
The client uses this value to differentiate packets that originated before the seek from packets that originated after the seek. A range of This enables the server to keep a single storage handle open easily. RTSP can also control multiple streams as a single entity.
See section 13 for further discussion of the expiration model. In other rrfc, a range of a-b starts exactly at time a, but stops just before b. Header type support methods Accept R opt.
It is specified as a range, e. It is interpreted according to [H The rcc is used by the client to compute the round-trip time to the server so that it can adjust the timeout value for retransmissions. 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.
If it is missing, a default value of zero is assumed. This information may also be available through SDP. Tfc may, for example, be the result of a resource reservation failure.
Instead, a not dfc response will be returned without any message-body. Indicates the sequence number of the first packet of the stream. The value of the timestamp is of significance only to the client and may use any timescale. For every RTSP request containing the given sequence number, there will be a corresponding response having the same number. For example, a ratio of 2 indicates twice the normal viewing rate “fast forward” and a ratio of 0.
Client C requests a presentation from media server M. A proxy might, for example, convert between video formats to save cache space or to reduce the amount of traffic on a slow link.

The mode parameter indicates rtc methods to be supported for this session. 226 specification defines the smpte Section 3. Sat, 29 Oct Please help to improve this article by introducing more precise citations.
If the cache is able to translate the cached media data, it would create a new presentation description with all the encoding possibilities it can offer. The following is an example of using a single RTSP session to control multiple streams.

A stale cache entry may not normally be returned by a cache either a proxy cache rcc an user agent cache unless it is first validated with the origin server or with an intermediate cache that has a fresh copy of the entity.
However, some vendors implement proprietary transport protocols.
A Transport request header field may contain a list of transport options acceptable to the client. The proxy delivers the continuous media data to gfc client, while possibly making a local copy for later reuse. This allows an origin server to rdc caching even by caches that have been configured to return stale responses to client requests. The address to which a stream will be sent. The default transport layer port number is  for both TCP and UDPthe latter being rarely used for the control requests.
