Abstract
An apparatus, method, and program for providing supplemental information related to video programs. Through a computer network interface, a user can request and receive specific supplemental audio/video information related to a video program. Alternatively, the supplemental audio/video information can be retrieved from a CD-ROM, or similar storage device. The video program can be, for example, a live broadcast television program or a time-shifted tape recording of a television program. The supplemental information is synchronized to the video program by using a time code which is integrated with the video program. This enables the supplemental information to be viewed and/or listened to in harmony with the events or action of the video program.
