Patent ID: 7739399

Claim:
Device for the adjustment of the bit rate of a stream of contents as a function of processing capabilities of at least one receiver, said processing capabilities being the resources of said at least one receiver fit for processing the data received, said contents being transmitted by a sender to said receiver via a network, according to a communication protocol providing for a return transmission of reception data of said contents by said receiver to said sender, said device comprising: a module for inputting information relating to said capabilities, a module for estimating a required level for said bit rate at least as a function of said information, and a module for writing stream adjustment cues that is intended to write said adjustment cues for return transmission with said reception data to said sender, said adjustment cues being capable of bringing about a modification of said bit rate in relation to said required level, wherein said communication protocol providing for a return transmission to said sender of at least one parameter of the protocol normally targeted at conditions of communication of said contents in said network between said sender and said receiver, the writing module is intended to modify said parameter in such a way as to use it to transmit said adjustment cues.
