Abstract: The invention concerns the decoding of a digital signal comprising at least one encoded digital image, a digital image being represented by a plurality of samples. The decoding method comprises, when a part of one said encoded digital image to be decoded is missing, applying a first decoding to the encoded digital image having the missing part so as to obtain a first decoded image, the first decoding involving setting a missing sample, being one of said samples in said missing part, to a first value. A second decoding is applied to said first decoded image using additional data, derived by the encoder from at least part of the encoded digital image and usable during decoding to correct the encoded digital image, to obtain a partially corrected symbol representative of said sample, said partially corrected symbol comprising at least one unknown bit. Finally, a second value for said missing sample is obtained based upon said first value and said partially corrected symbol. Thanks to this method, even a partial correction using additional data can be used to improve the values of missing samples of a digital image at the decoder side. As a result, the quality of reconstruction of missing parts of an image can be improved.

Abstract: A sequence of digital images encoded according to a predictive format is decoded using encoded auxiliary data which is representative of at least part of the sequence of digital images. A current encoded image, received with at least one detected error, is decoded. The decoding includes applying an error concealment decoding on at least part of the current encoded image containing such a detected error to obtain a first decoded image. An item of information representative of reconstruction errors is obtained based upon a reconstruction confidence of the error concealment decoding for at least one pixel of the error-containing part of the current image. The encoded auxiliary data and the first decoded image are processed based upon the item of information representative of reconstruction errors to obtain corrected auxiliary data. The first decoded image is modified to obtain a second decoded image based upon the corrected auxiliary data.

Abstract: The object of the method and devices according to the invention is the optimization of the transmission of data packets, transmitted by several sources, in a network, when there is interference. After having received a data packet and determined its source, this data packet is analyzed in order to determine whether data packets transmitted by this source have been lost. If data packets have been lost, the type of transmission error related to the source is determined and the transmission parameters are modified according to the type of error determined. The parameters for determining the type of errors are related to the comparison of the global loss rate for data packets related to this source with the global loss rate for data packets related to all the sources.
