Abstract
A system, like a video on demand server, retrieves blocks of data from a storage medium,and supplies the data to users in the form of at maximum n,data streams. Upon creation, a data stream is in a new state in which no sufficient data is present for consumption by a user, whereas a user may consume data for a data stream in an active state. A scheduler,repeatedly selects a group of data streams for which a data block of a predetermined size needs to be read and causes a reader,to read the data in one sweep and to store the read data in buffers,The group is formed by active data streams whose associated buffers,have room for storing the data block. The scheduler,variably determines the size of the data block for each next sweeping operation through an expression that, with respect to a number of data streams, is substantially based on an actual number n,of active data streams instead of n,.
