发明名称 METHOD FOR TRANSMITTING VIDEO SIGNAL
摘要 PROBLEM TO BE SOLVED: To reduce the number of wired video signal lines at transmitting of video signals from a plurality of video signal sources to one video recorder. SOLUTION: A switching means, which selectively switches the output of video signals to a video signal line M and the stoppage of the output to each other, is provided on the side of each of a plurality of video signal sources 1, and at the same time, one video signal line M connected in parallel with the video signal sources 1, is connected in advance to a reception-side device (video recorder 3). The video signals from the video signal sources 1 are transmitted through the video signal line M connected in parallel with the sources 1 by sending a select signal, which is used for selectively specifying one video signal source 1 out of the signal sources 1 from a selector 3 to the switching means of each signals source 1 through a select signal line L.
