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.
