ABSTRACT:
A digital video recording and playback system, and a method for recording video program information on a multiple-channel recording medium, such as tape. The system includes multiple playback devices, such as VCR decks. Each playback device outputs video program data from each of multiple channels of the recording medium at the same time. Synchronizing circuitry controls the playback devices so that alternately one is in playback mode while the other is in non-playback mode. The sequential outputs of the two playback devices can create a continuous and complete video program. One playback device is in playback mode while the other is rewinding. Because the video program data is recorded on the multiple channels with staggered starting times, little wait time occurs between the request for a program by a viewer and the start time of the program.
