Hi,
My home theatre reciever will only switch between two component video sources - but I need to switch between 3 or more.
Generally this means not only switching one of n sets of Y/Cb/Cr signals and associated L/R Audio (or possibly digital audio) but possibly also being smart enough to turn off via IR or RS232 command all the sources except the selected one and turning that one on. My A/V reciever can accept RS232 commands to turn on, and select the source that is the output of the AV switch.
This is all conceptually simple, but I have absolutely no idea about a good way to switch A/V signals. What's a good device to do this? I guess the big issue is to not introduce noise, interference or other signal degredation into the system.
There are off the shelf A/V switches around that do component video, but they are either expensive and/or don't have the smarts to be controled by I/R or RS232 nor control other devices by IR and RS232.
Any pointers or references?
Thanks
