    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: 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.

    Abstract: The methods for transmission of sequences or frames of data provide for retransmitting, with a central device (21), frames of data which reach it, to destination devices, by transmission of downlink frames when the destination device is a peripheral device (24), each downlink frame having systematically a service message activating a protocol controlling access to the transmission medium shared by the central device (21) and the peripheral devices (24), and possibly a frame of data. The central device (21) and at least one peripheral device (24) form a system which is particularly well suited to a local area network, notably with a wireless transmission medium.
