Abstract
The present invention provides a video signal transmission apparatus including: an optical transmitter that uni-directionally transmits video data from a video source; an optical receiver that receives the video data and outputs the received video data to a sink device; a first transmission medium that transmits the video data at a high speed; a second transmission medium that transmits identification information for identifying the sink device at a low speed; an identification information acquisition control section that acquires the identification information from the sink device; a storage section that stores general-purpose identification information used for plural types of sink devices; a acquisition possibility determination section that determines whether the identification information can be acquired from the sink device; and a general-purpose identification information reply control section that replies the stored general-purpose identification information to the video source device if determined that the identification information cannot be acquired.
