摘要： The present invention relates to a method and a device for choosing a mode of coding from among a plurality of modes of coding for a subset of blocks included in a set of blocks. An energy function over the set of blocks for each of the modes of coding is calculated and calculation elements of the energy function are stored for at least the subset of blocks. A first mode of coding, minimizing the energy function over the set of blocks is chosen. The energy function over the subset of blocks for each of the modes of coding is thereafter calculated by using the calculation elements stored for the subset of blocks and by said subset, of a cost of coding for the modes of coding distinct from the first mode of coding. The choice of a mode of coding minimizing the energy function over the subset is then effected.

摘要： A method and device for coding an image of a video sequence by image block using the time correlation between images based on movement field calculation. The method includes subdividing the images into blocks of images and a step for configuring the blocks into regions. A region corresponds to a succession of consecutive or non-consecutive blocks, according to the television scanning order of the image. In the inter- or intra-block coding step, the blocks are coded by region according to an ordering of the regions and a region according to the order of succession of the blocks that make up the region. The coded block error correction step includes analyzing the field of movement, a configuring step, and an error correction step. The step for analyzing the field of movement is carried out to calculate a “lifespan” parameter assigned to a block and corresponding to its probability of existence in subsequent images, according to the movement vector associated with this block. The configuring step is performed taking into account the value of this parameter to define and order the regions of the image from most important to least important. The error correction step uses a more effective error correction algorithm for the coded data corresponding to the most important regions than for the data corresponding to the least important regions.

摘要： The present invention relates to a device and a method for the preparation of data to be sent as a continuous stream via a communication network. The device comprises means for obtainment of the data originating from a database, which contains at least two data stream entities for data associated respectively with different transmission throughputs, means of transfer of these data to a sending system, means of connection to one of these entities, and means of switching of the means of connection from one of the entities to another. The preparation device also comprises means of regular addition to the data transferred, of error correction codes. The means of switching switch from a first entity to a second entity of greater throughput, when this augmented data stream reaches the sum of the sending throughput associated with the second entity and of an additional throughput associated with an initial input of error correction codes of the second entity, and the means of addition reinitialize the addition of the codes to this initial input upon this switching.
