ABSTRACT:
A process for source coding which divides image areas of an image, by use of a set of image statistics, into image areas to be intraframe-coded and interframe-coded and, by use of a movement estimation, additionally determines the image areas as foreground or as background. In the course of coding, in the first instance the image areas which belong to the foreground and are to be intraframe-coded are processed. Subsequently, the image areas which belong to the foreground and are to be interframe-coded are coded. Next, the image areas which belong to the background and are to be intraframe-coded are coded. Finally, the image areas which belong to the background and are to be interframe-coded are transmitted until the available data rate has been used up.
