Patent ID: 8832759

Claim:
A resource scheduling method, comprising: distributing, by computer hardware implementing process(es), bandwidth to a Video On Demand (VOD) program according to a received VOD user request and according to a transmission speed corresponding to bandwidth distributed to the VOD program at each time and a transmission time corresponding to the transmission speed, wherein the bandwidth is greater than a bandwidth that is occupied by an inherent code rate of the VOD program and within available bandwidth of a radio frequency point; and reducing, by the computer hardware, according to another received VOD user request as a currently requested VOD program, bandwidth distributed to at least one VOD program to which bandwidth has been distributed, when the available bandwidth of the radio frequency point is smaller than the bandwidth that is occupied by an inherent code rate of the currently requested VOD program, so that the available bandwidth of the radio frequency point is greater than or equal to the inherent code rate of the currently requested VOD program, wherein the reducing the bandwidth of the at least one VOD program is according to a formula R 1 T 1 +R 2 T 2 . . . +R n T n +XT x ≧CT c , wherein R 1 indicates a transmission speed corresponding to bandwidth distributed for a first time VOD program, T 1 indicates a transmission time corresponding to the transmission speed, R n i indicates a transmission speed corresponding to bandwidth distributed for an nth time VOD program, T n indicates a transmission time corresponding to the transmission speed R n , X indicates a transmission speed after the bandwidth of the at least one VOD program is adjusted, T x indicates transmission time required to complete the at least one VOD program transmission at the transmission speed X, C indicates an inherent code rate of the currently requested VOD program transmission, T c indicates time required to complete the currently requested VOD program transmission at the inherent code rate C of the currently requested VOD program transmission.
