Once initialized, its just a matter of bit banging to change the input channel. Some years ago I saw a simple 8 input board , bt848 based, who after such hack, worked fine. it has a 2x1 multiplexer in each input. Such cards aren`t so hard to find, many windows security and surveillance system use it, instead of those external video input mixers/multiplex. Regards
