Managing media resources utilizing session initiation protocol
View Patent ↗Provides management of the communication of media communicated to a Session Initiation Protocol (SIP) enabled multiplexer in a media distribution network. A SIP enabled multiplexer receives information from one or more components of the media distribution network to identify the status of the media distribution networks. Utilizing the information, a level of communication that media is to be communicated from a media source is determined. The level of communication is maintained until a request is received to communicate media from the media source. The request is compared to the determined level of communication at which the media is to be communicated. The media source receives an indication as to the level of communication that media is to be communicated. As a result, the media source communicates a request to communicate media at the indicated level of communication.
1. One or more nontransitory computer storage media having computer-executable instructions embodied thereon for performing a method for managing the communication of media communicated to a Session Initiation Protocol enabled multiplexer in a media distribution network, the method comprising:
at a first component of the media distribution network, receiving from a media source a first request destined for an intended recipient to communicate media at a first level of communication from the media source;
identifying the first level of communication contained within the first request, wherein the first level of communication requires a first amount of network resources and utilizes an H.263 standard;
prior to forwarding the first request to the intended recipient, determining whether the first level of communication exceeds a second level of communication, wherein the second level of communication is based on an available amount of network resources and utilizes an H.264 standard;
when the first level of communication exceeds the second level of communication, then instead of forwarding the first request to the intended recipient, communicating from the first component to the media source an indication that the media source is to communicate the media at a level commensurate with the second level of communication; and
upon receiving from the media source a second request that conforms with the level commensurate with the second level of communication, forwarding the second request to the intended recipient.
2. The media of claim 1 , wherein the second level of communication is determined based on a status of the media distribution network.
3. The media of claim 2 , wherein the status of the media distribution network is determined based on status information received from a second component of the media distribution network.
4. The media of claim 3 , wherein the status information is received from a Session Initiation Protocol (SIP) multiplexer.
5. The media of claim 4 , wherein the status information includes one or more of transport error rate, synchronization information, bit error rate, latency, or bandwidth constraints.
6. The media of claim 3 , wherein the status information is received from the second component of the media distribution network at a regular interval.
7. The media of claim 3 , wherein the status information is received from the second component of the media distribution network at an interval that is based on whether an item of the status information exceeds a threshold.
8. The media of claim 1 , wherein the second level of communication is determined based on a result of a transport error rate exceeding a predefined threshold.
9. The media of claim 1 , wherein the second level of communication is at least one from the following:
a compression ratio;
a transfer rate; or
a communication standard.
10. The media of claim 1 , wherein communicating at the second level communicates less media per unit of time than communicating at the first level.
11. The media of claim 1 , wherein the media distribution network is at least one selection from the following:
a cable television network;
a Direct Subscriber Line network; or
an Internet Protocol network.
12. A method for managing the communication of media communicated to a Session Initiation Protocol enabled multiplexer in a media distribution network, comprising:
at a first component of the media distribution network, receiving from a media source a first request destined for an intended recipient to communicate media at a first level of communication from the media source;
identifying the first level of communication contained within the first request, wherein the first level of communication requires a first amount of network resources and utilizes an H.263 standard;
prior to forwarding the first request to the intended recipient, determining whether the first level of communication exceeds a second level of communication, wherein the second level of communication is based on an available amount of network resources and utilizes an H.264 standard;
when the first level of communication exceeds the second level of communication, then instead of forwarding the first request to the intended recipient, communicating from the first component to the media source an indication that the media source is to communicate the media at a level commensurate with the second level of communication; and
upon receiving from the media source a second request that conforms with the level commensurate with the second level of communication, forwarding the second request to the intended recipient.
13. The method of claim 12 , wherein the second level of communication is determined based on a status of the media distribution network.
14. The method of claim 13 , wherein the status of the media distribution network is determined based on status information received from a second component of the media distribution network.
15. The method of claim 14 , wherein the status information is received from a Session Initiation Protocol (SIP) multiplexer.
16. The method of claim 15 , wherein the status information includes one or more of transport error rate, synchronization information, bit error rate, latency, or bandwidth constraints.
17. The method of claim 14 , wherein the status information is received from the second component of the media distribution network at a regular interval.
18. The method of claim 14 , wherein the status information is received from the second component of the media distribution network at an interval that is based on whether an item of the status information exceeds a threshold.
19. The method of claim 12 , wherein the second level of communication is determined based on a result of a transport error rate exceeding a predefined threshold.
20. The method of claim 12 , wherein the media distribution network is at least one selection from the following:
a cable television network;
a Direct Subscriber Line network; or
an Internet Protocol network.
