Patent attributes
In conventional technology, when a program which operates in synchronization with reproduction of video and audio instructs a trick play of video and audio such as fast-forward and rewind, the trick play of the video and audio continues even after the program is terminated. This makes it impossible to cancel a redundant trick play which continues for an interval of time which is not expected by the program. In the present invention, a program which instructs a trick play of video and audio is retained, and when the program is terminated, it is determined whether or not the program has instructed the trick play, and if that program has instructed the trick play, the trick play of the video and audio is cancelled. As a result, it is possible to cancel such a redundant trick play which would otherwise continue for some interval of time which is not expected by the program.
