ABSTRACT:
The present invention relates to a method for regulating, in the read mode, memory areas of a circuit for decompressing a video data flow compressed according to an MPEG standard, with respect to the writing rate of the compressed data flow into the memory areas, the decompression circuit issuing a flow of image data at the rate of signals for horizontally and vertically synchronizing the images issued by a circuit for coding according to a color television standard, this method including generating a clock signal having a fixed frequency for reading from the memory areas and for generating the horizontal and vertical synchronization signals, and shifting the occurrence of an edge triggering the vertical synchronization signal based on a signal indicative of the state of a buffer memory associated with the memory areas.
