The authors report on a method of delivering multiple aspect videos on demand as an application for broadband video communications. Their method is a client-server video delivery system with the user's terminal representing the client Multiple aspect video programs such as for viewing sports or pursuing education are stored and managed. Each program consists of a group of synchronized video with several aspects, and contents are created and managed in units of individual aspect videos. The user selects a program from the terminal, then directs the delivery and playback of the desired aspect video by selecting the aspect video. Aspect switching is performed by switching to a separate aspect video while the progress of the video being played back is maintained. In addition to proposing 1 a method to control groups of program content, 2 a method to switching aspects at high speed using a quick start video, 3 a method to dynamically and efficiently set the quick start video, and 4 a method to reduce the displacement width with respect to the time displacement accompanying the connection to new and old aspect videos, the authors report on experimental results and a performance evaluation.
