OPTIMAL VIDEO DECODER BASED ON MPEG-TYPE STANDARDS

摘要

The invention concerns a method for decompressing compressed animated images by a method comprising a block image processing and comprising a step for reconstructing digital data defining predefined forms, a step for modelling the movement of said forms using a forecast, interpolation and time compensation procedure, a step for composing the image from the reconstructed elements, of the Motion-JPEG, or MPEG type. The invention is characterised in that the step reconstructing the forms comprises a process of separating still forms from mobile forms, a process of recording digital data corresponding to the processed still forms by a filter indissociable from the processes used in the reconstituting step in a first specific memory and digital data corresponding to mobile forms in a second specific memory.
