Patent ID: 7712121

Claim:
A method for controlling a processing of video data including coding or transcoding of video data such that said video data may be transmitted over a connection in a communication network from a source to a receiver, said connection employing a plurality of protocol layers, said method including: performing said controlling of the processing of video data at a first application layer in said source, acquiring from a network control element separate from said source and said receiver a value of one or more transmission condition parameters indicative of transmission conditions in the network, where said one or more transmission condition parameters are specific for a second layer provided lower than said first application layer, deriving one or more values of one or more video control parameters from said value of said at least one transmission condition parameter, providing to said first application layer said derived one or more values, and performing at said first application layer said controlling of the processing of video data including coding or transcoding of video data in accordance with said derived one or more values, wherein said communication network includes a wireless communication network, said connection comprises a radio link for transporting a mobile communication including video data between a mobile station in said wireless communication network and a radio base station in said wireless communication network, said mobile station being currently located in a first cell coverage area, and said one or more transmission condition parameters include information pertaining to one or more handover conditions associated with handing over the mobile communication to a second cell coverage area, and wherein the information pertaining to one or more handover conditions includes information relating to a capacity of the second cell for adapting the coding or transcoding of video data in accordance with that information.
