IR remote sleep?

I want to implement a sleep/wake button.
Sleep should do the following:
dim the lcd (=backlight off)
stop/pause the playback after say 60min. (I want to continue when I press a wake button)

I can see how to set a sleep on the web page but no way of doing it by a remote control, and I can’t see any way of turning off the backlight via lcdproc.
