just buy any universal remote that lists "Macro" or "Activity" buttons and it will turn on or off any components you want for that activity in the order you specify. They will also go several menus deep into you TV and other components to get the job done (swtiching from Video 1, 2, etc. in TV menues for instance). Obviously, they have to be programmed which you do by hooking it up to your computer via USB and accessing the manufaturers web site. The site will walk you through programming the remote the way you want it. Another big decision is whether or not to stick with infra red or spend a little extra on radio frequency. RF eliminates the need for line of sight or even being in the same room as the TV.
Mine doesn't have an internal timer, clock or sleep button but I could certainly program a button to activate the timer function on my TV or any other device with it's own timer. Sleep function on a remote that would shut down all components in a specified sequence using it's own timer is going to narrow the selection. I don't know which brands and models might have it. I've never thought of that before but it's a good idea.
...that can control an A/V receiver, TV, Cable box
is able to switch the input/ source from the TV (ex. from HDMI to VGA... etc.) and the audio output on the receiver (ex. Video 1, Video 2, TV, DVD... etc...)
has a SLEEP button to function for all devices????
If anyone wants to suggest anything, I would really appreciate it. Thanks.
