Abstract:
A Video On Demand system sending data to requesting terminals, comprising:a plurality of disk memory devices coupled to a bus, each of which is allocated time slots to sequentially store divided data of a program;a buffer memory storing data read out from the plurality of disk memory devices and reading out the stored data to be sent to the requesting terminals;a controller, coupled to the buffer memory, controlling to start counting a period during which the bus is occupied for one time slot, if the ""i+1""th time slot is assigned to no user, but the ""i+2""th time slot is assigned to a user, and controlling to read out data for the ""i+2""th time slot from the buffer memory, so as to follow reading out of data for the ""i""th time slot, after the period is counted up; andan interface circuit, coupled to the buffer memory, to the controller, and to the requesting terminals, sending the read out data to the requesting terminals.
