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.
