Problems solved by technology

Therefore, "sender-based" adaptation is highly limited by the fact that the receiver's feedback in RTP is not regular enough and limited to a few "basic" quality metrics

Embodiment Construction

[0129] Figure 6 An example of a system for two-way communication between two terminals A and B is shown, implementing a request signaling method according to an embodiment of the invention. As in Fig. 1, microphones and speakers (101, 151, 102, 152) have been shown. For simplicity and clarity, the operation of the acoustic treatment and the network connecting the two terminals are not in the Figure 6 shown in .

[0130] Terminal A includes a transmitter 601 and a receiver 603 , while terminal B includes a transmitter 651 and a receiver 653 . Typically, the two terminals A and B are configured via respective blocks 600 and 650 in accordance with the exchange of one or more offers / one or more replies according to the SDP protocol. Typically, this SDP configuration is employed at least during the instantiation (initialization or re-initialization) of the transmitter and receiver; in a variant of the invention, this configuration can be considered terminal-internal and allows...

Abstract

The present invention pertains to a method for signalling an adaptation request to adapt to the coding / decoding of real-time signals of a real-time communication session, from a receiver device to a sender device. According to the method, the adaptation request relates to a demand for aggregation and / or redundancy of frames, is generated according to the existence of a signalling parameter arisingfrom the phase of negotiation of 10 codecs used during the initialization of the communication session and is transported via a real-time protocol of RTP type. The invention also pertains to a receiver device implementing the method described as well as to a terminal comprising the device.

Description

technical field [0001] The present invention relates to the field of telecommunications, and more particularly to the field of packet communication networks. In this type of network, data streams associated with real-time services can be transmitted. [0002] The Internet Protocol (IP), developed by the IETF (which stands for Internet Engineering Task Force), is implemented in packet communication networks to support non-real-time services (such as data transmission services, website browsing services, and electronic messaging services) and real-time or conversational services (such as IP telephony, IP video telephony or even IP video streaming) both. [0003] The invention relates more particularly to the signaling of an adaptation request requesting adaptation of the encoding / decoding of a real-time signal, such as a speech signal or a video signal, during a real-time communication session between two communication terminals. Background technique [0004] An example of a...
