[snip] If you can write down the numbers on the other auxiliary ICs and hunt them down on the Internet, you could get quite far. It is my guess one of them is a 16-to-1 demultiplexer (or some cascaded design), and chances are the 4 pins that select the input are connected to the GPIO port of the bt848, like most TV cards. In that case you can extend the current bttv_card structure with the mask bits, and off you go... NB: not related to this thread: if you must switch between that many cameras there is probably a sync-out signal as well, so that all cameras can be synced and switching latencies are minimal. Might be worth finding the signal. > Could anybody provide me some starting points? What should i look for to > make it work?

Not much; look at the current bttv driver; the only difference is between the number of inputs and the values necessary for the input demultiplexer. - Nemosoft
