摘要： A trellis filtering of a digital signal is disclosed. A method is provided of analysis filtering of an original digital signal including original samples representing physical quantities. Original samples of the digital signal are transformed by successive calculation steps into high and low frequency output samples. Any sample calculated at a given step is calculated by a predetermined function of original samples, and/or previously calculated samples, the samples being ordered in increasing rank. The signal is processed by successive series of samples, the calculations made on any series not taking into account the samples in a following series, and in that the any series terminates in a low-frequency sample.

摘要： A method and a device by which original digital signals are analysis-filtered, where the original digital signals include original samples representing physical quantities, and where the original samples are transformed by successive calculation steps into high and low frequency output samples. Any sample calculated at a given step is calculated by a predetermined function of the original samples and/or previously calculated samples, where the samples are ordered by increasing rank. The signal is processed by successive input blocks of samples, where the calculations made on an input block under consideration take into account only the original or calculated samples belonging to the input block under consideration, and where the input block under consideration and the following input block overlap over a predetermined number of original samples. Output blocks are formed, where each output block corresponds respectively to an input block.

摘要： 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.

摘要： A method of encoding a digital image signal comprising a plurality of samples. The method comprises the following steps, applied during the encoding of each sample with a view to its storage in a buffer. The level of occupancy of the buffer is determined, and the level of occupancy is compared with a predetermined threshold. An encoding mode is determined from among a plurality of encoding modes when the level of occupancy is above the predetermined threshold, and encoding the sample according to the determined encoding mode, and the sample is encoded according to a default encoding mode when the level of occupancy is below the predetermined threshold.
