Patent Issued for Managing Media Resources Utilizing Session Initiation Protocol

By a News Reporter-Staff News Editor at Journal of Engineering -- According to news reporting originating from Alexandria, Virginia, by VerticalNews journalists, a patent by the inventors Pankajakshan, Bejoy (Olathe, KS); Dhanoa, Shingara Singh (Overland Park, KS); Hiser, Randolph Keith (Overland Park, KS), filed on December 9, 2008, was cleared and issued on December 4, 2012.

The assignee for this patent, patent number 8325605, is Sprint Communications Company L.P. (Overland Park, KS).

Reporters obtained the following quote from the background information supplied by the inventors: "Media streams are typically aggregated into a transport stream for communicating the media across cable television networks, satellite networks, and Internet provider networks. The aggregation of multiple media streams into a transport stream is generally performed by a multiplexer. Typically, media is communicated through an upstream network before being multiplexed into a transport stream or encapsulated for delivery in a TCP/IP environment. The transport stream is then communicated through a downstream network for distribution to one or more end users. Unfortunately, available resources in networks upstream and downstream of a multiplexer vary depending on conditions and demands. Therefore, resources upstream of a multiplexer are ineffectively utilized when media is communicated at a quality, compression, or standard that exceed the resources available in a downstream network.

"Available resources, user preferences, and device capabilities typically result in contention when communicating media from a media source to be multiplexed and eventually communicated to an end device. For instance, a media source, such as a mobile communications device, may request to communicate media, such as a captured video, at a high quality level. But, unknown to the media source, sufficient resources are not available further down stream in the communication flow of the media to support the requested level of quality. Therefore, the media source utilizes greater resources than necessary to begin the communication of the media at a higher quality level than is supported at a later point in the communication of the media."

In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventors' summary information for this patent: "Embodiments of the present invention relate to systems, methods, and computer storage media for managing the communication of media communicated to a Session Initiation Protocol (SIP) enabled multiplexer in a media distribution network. Embodiments of the present invention include negotiating resources across one or more networks to effectively communicate media. The methods include receiving information from a SIP enabled multiplexer indicating a level of communication at which media is to be communicated from a media source. The methods also include receiving a request from the media source to communicate media from the media source at a level different than the level indicated by the SIP enabled multiplexer. The methods additionally include communicating to the media source an indication that media is to be communicated at a level commensurate with the level indicated by the SIP enabled multiplexer. The methods also include receiving a second request from the media source to communicate media at the indicated level of communication.

"This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter."
