Abstract
The present invention relates to a video server memory management for a video server transmitting video signals (VS) to user stations in response to control signals issued by these stations. This method includes the steps of providing a memory constituted by a plurality of random access memories (HD1/ . . . /HD4) and subdividing each of said video signals in a plurality of distinct blocks (BL1/ . . . /BLQ) each typically corresponding to less than a second of the video signal. It is further proposed to include in this method the step of storing any two blocks (BL1/ . . . /BLQ) which normally are to be consecutively retrieved from the memory in distinct random access memories (HD1/ . . . /HD4). In this way the full interactive video on demand service, giving the user stations control over the way in which the blocks are retrieved from the memory, is improved as is the rate at which a predetermined sequence of blocks is retrieved from the memory.
