Abstract
The present invention relates to a device and a process for adjusting the bit rate of a stream of contents as a function of processing capabilities of at least one receiver. These contents are transmitted by a sender to the receiver according to a communication protocol providing for a return transmission of reception data of the contents by the receiver to the sender, including at least one parameter relating to conditions of communication of these contents in the network. The device comprises a module for estimating a required level for the bit rate as a function of information relating to these capabilities and a writing module modifying this parameter, to transmit, in return, to the sender stream adjustment cues capable of bringing about a modification of the bit rate in relation to the required level. Application to streaming.
