Abstract: Techniques are provided for encoding and decoding image data. The techniques implement a prediction of data of a current block based on at least one already encoded block or reference block, wherein said prediction step takes into account a set of encoded blocks adjacent to said current block and including blocks that have not yet been considered according to said writing path order. Encoding includes the steps of: generating a dependence tree associating a current block with at least one reference block from which the predicted block associated with the current block has been predetermined; and inserting information representative of said dependence tree into said set of data associated with each block.

Abstract: Data associated with transmitted information over a communication network are transmitted. The data are divided into data groups. An information item representative of the importance of the data of the data group is associated with each data group. A transmission cycle for the data groups is determined.

Abstract: A video image sequence including coefficients of frequency sub-bands with different spatial resolutions is coded. A data stream including at least one restitution level (Niv N−2, Niv N−1, Niv N) is formed. The restitution levels have coefficients of frequency sub-bands whose spatial resolution equals a spatial resolution of the restitution level. There are inserted, in at least one restitution level, coefficients of frequency sub-bands with a spatial resolution higher than the spatial resolution or resolutions of the restitution level.

Abstract: In order to code a digital signal, a simplified version of the digital signal is determined, containing only some of the information contained in the digital signal. The simplified version is coded by means of a predetermined single coding technique. This simplified version is subtracted from the digital signal, so as to obtain a residual signal. From each block of the simplified version, there is selected, for each corresponding block of the residual signal, a coding technique amongst a predetermined number M of coding techniques Ci, where i is an integer between 1 and M. Each block of the residual signal is coded by means of the previously selected coding technique.
