PROCESS AND DEVICE FOR CODING VIDEO IMAGES

A process and device for coding video images using a non object-based coding standard that extracts at least one video object from an image originating from a sequence of images, by the construction of a segmentation key defining the contours of the object in the image. The video object is coded according to the MPEG 2 standard so as to form an elementary stream (ES). The segmentation key relating to the video object is coded according to the MPEG 2 standard, so as to form an elementary stream. A background image into which the object is to be inserted is coded according to the MPEG 2 standard, so as to form an elementary stream. The elementary streams relating to one or more objects and to the background image are multiplexed so as to provide a program stream (PS) or transport stream (TS) according to the MPEG 2 standard.
