MULTIMEDIA DEVICE CONTROLLER, SOURCE DEVICE, SYNC DEVICE AND TRANSMISSION SYSTEM

摘要

Disclosed are a multimedia device controller, a source device, a sync device and a transmission system that can manage multimedia devices capable of simultaneous output of video and audio from multiple Blu-ray discs or the like. A master device (110) references a source/sync device function management table (200) and a band management table (300) and controls the video and audio bands for the source and sync devices during transmission of multiple video and audio signals. When a secured band is changed, the master device (110) also confirms the status of a transmission path (100) and the content usage conditions of sync devices (140, 150) and controls the band. For example, when the master device (110) outputs two sets of video and audio in one set, the band is changed to one band in which the two sets of video and audio are synthesized.
