摘要:
The present invention relates to a video server (DS) for transmitting video signals (VS) to user stations in response to the receipt of control signals issued by these user stations and including a plurality (HDA) of memories (HDASA, HDASB) which are controlled by a plurality of memory controllers (OBC, SCSIC-A/B).
It is proposed to control the memory controllers based on said control signals by a server control means (DSC, PCM1/PCMN) which includes a server controller (DSC) and a plurality of program control modules (PCM1/PCMN) each of which is associated to a subset (HDA1/HDAN) of said plurality (HDA) of memories (HDASA, HDASB) and to a subset of said plurality of memory controllers (OBC, SCSIC-A/B).
This server control means is kept relatively simple if said server controller activates for each requested video signal the program control module in which associated subset of memories this video signal is stored and if this program control module, upon being activated, operates its associated memory controllers to achieve said transmission.
