Abstract
A resource scheduling apparatus, a resource scheduling method, a program requesting method, a program requesting system, and a Set Top Box (STB) are provided. The resource scheduling method includes: distributing bandwidth greater than an inherent code rate of a program respectively requested by a user to a Video On Demand (VOD) program of the user within available bandwidth of a frequency point according to a received VOD user request; and reducing the bandwidth distributed to at least one VOD program to which bandwidth has been distributed according to the received VOD user request for currently requesting the program when the available bandwidth of the frequency point is smaller than an inherent code rate of a currently requested program, so that the available bandwidth of the frequency point is greater than or equal to the inherent code rate of the currently requested program. Thus, a transmission speed of the program and a utilization ratio of the bandwidth are increased.
