A method, receiver device and terminal for signaling an adaptation request to adapt a coding/decoding of real-time signals of a real-time communication session, from a receiver device to a sender device. The method is such that the adaptation request relates to a demand for aggregation and/or redundancy of frames, that it is generated according to the existence of a signaling parameter arising from a phase of negotiation of codecs used during initialization of the communication session and in that it is transported via a real-time protocol of RTP type.

Signaling of a request to adapt a voice-over-IP communication session

A method for adapting an encoding bitrate of real-time signals of a real-time communication session between sender devices and receiver devices of communication terminals. A sender device includes a multi-bitrate encoder using a set of discrete bitrates. The method includes a test step of increasing the encoding bitrate at the sender device by transmitting at least one redundant packet according to selected transmission parameters. A method is also provided for determining a request to adapt the encoding bitrate of real-time signals in order to implement a test of increasing the encoding bitrate at the sender device by transmitting at least one redundant packet according to selected transmission parameters. A sender device and a receiver device implementing the methods are provides as well as a terminal containing these devices.
