Method for dynamically adapting the encoding of an audio and/or video stream transmitted to a device

摘要

The present invention concerns a method for dynamically adapting the lossy encoding of an audio and/or video stream (112) transmitted by a first device (101) to a remote device (102), said method comprising the following steps: the remote device (102) receives and decodes said stream (112), called the incoming stream, and transmits an outgoing stream (111) having at least one indicator relating to a state of said remote device (102) that is modified by the execution of the decoding of the incoming stream (112); the first device (101) receives the outgoing stream (111), extracts said at least one indicator therefrom and adapts the encoding of the incoming stream (112) according to said at least one extracted indicator. The method can be applied notably to video conferences conducted on the basis of self-powered terminals for the purpose of maintaining the operating period of these terminals.

1. A method for dynamically adapting the lossy encoding of an audio and/or video stream transmitted by a first device to a remote device, said method comprising at least the following steps:
the remote device receives and decodes said audio and/or video stream, called the incoming stream, and transmits an outgoing stream from the remote device, said outgoing stream having at least one indicator translating a power saving rate desired by said remote device, said indicator corresponding to a reduction rate in decoding operations for the incoming stream into the remote device or in processor P processing cycles, the first device receives the outgoing stream from the remote device, extracts said at least one indicator therefrom and adapts the encoding of the incoming stream into the remote device according to said at least one extracted indicator.
