Abstract
These exemplary embodiments utilize Sessions Initiation Protocol (SIP) for admission control. The use of the SIP allows a SIP server itself to perform the admission control function. The use of RSVP linkages is reduced. The use of SIP for admission control allows an application to communicate, or “talk,” to a network and to request that resources within the network be reserved. Any communications device that uses sessions may utilize the SIP protocol for admission control. The SIP protocol may be used for unicast and multicast media sessions including video-on-demand and/or multicast video access control.
Claims18
A method for providing media delivery services comprising:
- receiving a session initiation protocol invitation from a multimedia device to request a media stream, the invitation further comprising a private communications address for communicating with the multimedia device;
- communicating the session initiation protocol invitation to a multimedia content server via a communications network;
- receiving a session initiation protocol confirmation from the multimedia content server via the communications network to communicate the media stream, the confirmation further comprising a communications identifier for identifying the media stream;
- receiving and identifying the media stream from the multimedia content server via the communications network;
- and
- communicating the media stream to the private communications address of the multimedia device.
A method for providing a media stream to a multimedia system comprising:
- ordering a media stream via a session initiation protocol invitation over a communications network to a content media source;
- and
- communicating the media stream to a private communications address of a multimedia device.
A method for providing a media stream to a multimedia system comprising:
- initiating an order for a media stream via a session initiation protocol invitation over a communications network, wherein at least one multicast multimedia content server accesses, stores, and manages the media stream;
- translating the session initiation protocol invitation to an internet group management protocol join;
- communicating the internet group management protocol join to order the media stream from the at least one multicast multimedia content server;
- receiving an internet group management protocol acknowledgement via the communications network, the acknowledgement further comprising a communications identifier for identifying the media stream;
- identifying the media stream and communicating the media stream to a private communications address of a multimedia device.
A system comprising:
- a media stream source in communication with a multimedia content server, the media stream source for storing a media stream;
- the multimedia content server for accessing the media stream, managing interactive controls of the media stream, and communicating the media stream;
- and
- at least one processing device using a session initiation protocol communication of a multimedia device to order a media stream from a multimedia content server via a communications network, wherein the at least one processing device comprises instructions for receiving the session initiation protocol invitation from the multimedia device to request a media stream, for communicating the session initiation protocol invitation to the multimedia content server via the communications network, for receiving a session initiation protocol confirmation from the multimedia content server via the communications network to communicate the media stream, for receiving and identifying the media stream from the multimedia content server via the communications network, and for communicating the media stream to a private communications address of the multimedia device.
The system of claim 21, further comprising a distribution network over which the multimedia content server communicates with the at least one processing device.
A storage medium on which is encoded instructions for performing the following:
- receiving a session initiation protocol invitation from a multimedia device to request a media stream, the invitation further comprising a private communications address for communicating with the multimedia device;
- communicating the session initiation protocol invitation to a multimedia content server via a communications network;
- receiving a session initiation protocol confirmation from the multimedia content server via the communications network to communicate the media stream, the confirmation further comprising a communications identifier for identifying the media stream;
- receiving and identifying the media stream from the multimedia content server via the communications network;
- and
- communicating the media stream to the private communications address of the multimedia device.
