I was looking through this old thread about composite video cropping in the interest of creating my own analog 'video wall' type setup.
I want to take in a single video signal and split it out to say 9 tvs. I was imagining splitting the signal and sending it to 9 modules that crop and zoom the incoming signal so only a section of the video plays on each tv. I know this can be done with a raspberry pi video wall setup, but I am more interested in an analog way, more of a learning project then anything super practical. Does anyone have any insight into how the old analog video wall systems worked on a circuit level? its been hard to find much electronics information on the old systems..
