Hi Tom,

Most TV's- Even my old Magnavox have a button (Or IR Code) that will call up
the previous channel the TV was on.  Kind of like a recall button or LAST
channel button.  That is what I use.  So when a call comes in, you change
all TVs to the HV channel (using individual IR codes).  After the HV
displays the CID info and after a specific interval, send the LAST channel
IR codes to the TVs.  This should put all TVs back to the channel they were
on.  As long as the codes for the TVs are independent and don't interfere
with each other you should be able to use the same connecting block.

Good Luck

Kevin

Thanks for the replies. I guess I'll have to go for the dedicated HV
channel. Any thoughts on what would be the right modulator to use? Also,
since I'll need to change 4 different models of TV's (unfortunately none
have PIP) can I use a simple 4 output amplified IR connecting block and send
the signals out to all TV's? How do I know which channel each set was on
before changing to the HV channel, so that I can switch back?

Thanks,

Tom
