A requested title recognizing mechanism recognizes the title of a video requested by the subscriber. A VOD service state monitoring mechanism determines whether or not the broadcast of the video is to be provided in the FVOD or the NVOD service, and if there is any available channel for the broadcast. If the broadcast has not been switched from the FVOD service to the NVOD service, then a busy state monitoring mechanism checks the number of the current simultaneous subscribers for the video. If the number is equal to or larger than a threshold, then the busy state monitoring mechanism instructs an NVOD service providing mechanism to broadcast the requested video in the NVOD service. If the number is smaller than the threshold, then the busy state monitoring mechanism instructs an FVOD service providing mechanism to broadcast the requested video in the FVOD service.
