I recently built this widget for my parents. Their TV set has only one audio/video input and they have two video sources, a VCR and DVD player. The VCR has two inputs, but using the DVD player involved switching both the VCR and DVD player on and selecting the proper input on the VCR and TV set. I thought it made sense, but they had trouble with it. I designed and constructed this audio/video auto switch to make the switching more automated. The video B input detects the voltage from the video output of the DVD player and connects the DVD player (video B) to the TV set (video COM). When the DVD player is switched off, the VCR is connected to the TV set (video A). If anyone finds this useful, please let me know. Also, I thought of designing a printed circuit board and fitting it into a standard enclosure. Would anyone be interested in purchasing the bare PCB, Assembled PCB, and/or complete assembly?
