VIDEO SIGNAL TRANSMISSION APPARATUS, IDENTIFICATION INFORMATION ACQUISITION METHOD FOR VIDEO SIGNAL TRANSMISSION SYSTEM AND COMPUTER READABLE MEDIUM STORING IDENTIFICATION INFORMATION ACQUISITION PROGRAM FOR VIDEO SIGNAL TRANSMISSION SYSTEM

摘要

PURPOSE: A video signal transmitting apparatus and recording medium for recording an identification information obtaining program are provided to transmit a video signal from a video source device to a synchronizing device even though a dedicated cable for transmitting a control signal is removed. CONSTITUTION: An optical transmitter(16) transmits video data. An optical receiver(18) receives the video data. An identification information acquisition controller obtains identification information from a synchronizing device. An acquisition determining unit determines whether the identification information is received from the synchronizing device. A general-purpose identification information returning controller returns the identification information to a video source device(10).
