Abstract

The present invention discloses a method for providing video-on-demand, the method comprising : after a video-on-demand server having received an on-demand request from a video-on-demand terminal, it transmitting the program data being demanded to the video-on-demanding terminal in an unicast form; building a multicast for vedio-on-demand terminals which demand the same program data as the said program data, transmitting the said program data in a multicast form, and informing the information on said multicast to the video-on-demand terminals which demand the same program data as the said program data; confirming the coincidence between the unicast program data and the multicast program data, terminating transmitting the program data to the video-on-demand terminals in the unicast form. The present invention also discloses a method ofvideo-on-demand, a server for video-on-demand and a terminal for video-on-demand.
