  • Method and device for coding a mosaic
    Patent number: 8160159
    Abstract: The process for coding a mosaic of images giving a stream of coded data the mosaic being composed of subimages, the subimages being composed of image elements, resynchronization markers in the stream allowing resynchronization of the data at reception level, wherein the subimages are placed under one another in the image to be coded so as to give a mosaic, the mosaic is coded element by element according to a TV-type scan so as to provide data of the stream, the first element of each subimage being identified, and a resynchronization marker is placed in the stream, before each first element of a subimage, so as to identify the data relating to the subimage.

  • Process for the format conversion of an image sequence
    Patent number: 7415068
    Abstract: A process for converting the format of an image sequence wherein, for a coded pixel group to be converted, if the mode of coding used is of the inter type with no residue, the conversion is performed by a copy of a converted pixel group of a preceding image linked by the motion vector associated with said coded pixel group.

  • Method and device for coding a scene
    Publication number: 20040258148
    Abstract: The process for coding a scene composed of objects whose textures are defined on the basis of images or parts of images originating from various video sources is disclosed by spatially composing an image by dimensioning and positioning on the image, the other images or parts of images originating from various video sources, as to obtain a composed image, and, calculating and coding auxiliary data comprising information related to the composition of the composed image and information related to the textures of the objects.
