Abstract (en)
[origin: WO2006075061A1] Successive images (F) of a video sequence 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 effected in Inter mode relative to one or several previous images of the sequence. The output flow also includes long term marking commands for certain images and demarking commands for previously marked images. Each long-term marked image is kept in a memory by the decoder until a corresponding demarking command is received. Return information on the restoration of the images of the video sequence by the decoder is received by the encoder (1) and analyzed in order to identify an image that has been lost by the decoder. It is possible to encode a following image of the sequence in Inter mode in relation to a long-term marked image in response to identification of an image lost to the decoder.
