video data processing module acquires a video processing unit whose configuration is programmable uniqueness entry bus

According to the invention, the video data processing and programming data are sent to the module via a common data bus. These modules are advantageously concatenated in series on a common bus which routes each module both configuration data and video data to be processed. Preferably, use of dead time periods or "blanking" between two frames of images transmitted on this bus to insert the programming data.
