摘要： The invention concerns a video coding method which consists in: a) encoding successive images (F) of a video sequence to generate encoding parameters; b) including the encoding parameters in an output stream (F) to be transmitted to a station (B) comprising a decoder (2); c) receiving from said station return data on the restoration of the images of the video sequence by the decoder; d) analyzing the return data in order to: d1) identify among the restored images, if at least one image includes at least one part which has been lost at the level of the decoder, d2) identifying, among the successive encoded images between said restored image and a current image to be encoded, at least one image part which refers to said lost part identified at step d1); e) encoding said current image of the video sequence in accordance with an encoding mode which is based on the identification or non-identification of at least one lost part as performed at step d).

摘要： The process involves reconstructing images from video flow, where each reconstructed image is constituted in blocks of juxtaposed pixels. Each image block of a part of reconstructed video images is analyzed by comparing pixels of the block situated all along a part to adjacent pixels belonging to neighborhood blocks to detect wrong blocks by an error detector (6). The wrong blocks are corrected by an error corrector (7).
