RE: [mh] Controlling Access to Television

If you were using video signals I'd have the solution for you (I just
started working on a driver for the Inday serial-controlled products
(http://www.inday.com/index.html).

The remote A/B switchers I've seen (had one of the Radio Shack ones) have
switches on them to manually flip from one to the other. First thought if
you're trying to avoid I/R is to remove that switch and use a relay
controlled by a Weeder Digital I/O board (or other controlling I/O, like an
output from an Omni alarm/automation panel) to do the switching. Take a bit
of soldering but it should be a fairly simple project.

Subject: [mh] Controlling Access to Television


Now that summer is here and the kids are spending more time at home, I'd
like to implement a method of automatically controlling access to the
television.  I've looked around on the net for the necessary hardware.
The most common approach seems to be to cut the power to the set.  This
seems kind of inelegant and it would make my set loose its memory.  I'd
prefer to simply switch the cable signal off with a relay.  I am afraid
that a conventional relay would mess up the signal -- being unshielded
as it is.  There are some A/B switches controlled via IR that could work
but I'd like to avoid the IR part in preference for a hardwired
connection to a weeder board.

Does anyone have something implemented to do this?  What hardware did
you end up using?

Thanks for the help!
