Abstract (en)
[origin: WO2006075070A1] Successive images (F) of a video image are encoded in order to generate parameters which are included in an output flow (F) that is to be transmitted to a decoder. The encoding of certain images is carried out in inter mode in relation to one or several previous images of the sequence, said previous images being temporarily stored in an image memory (51). Return information on the restoration of the images of the video sequence by the decoder are received by the encoder (1) and analyzed in order to evaluate the time lag of the return channel in relation to the transmission of the output flow. The encoder determines an amount of memory allocated to the image memory in the decoder according to the evaluated time lag and indicates said amount of memory to the decoder.
