If it does then what the OP is wanting should be possible, you could write a bash script that checks XBMC CPU usage and run the above command when it's idle. Of course this wouldn't work 100% of the time because the "home screen" idle usage is almost as high as when playing certain video content. Also if you found yourself on certain plug-in screens or other high CPU usage screens this wouldn't work.

tvservice -o turns off HDMI on RPI but this takes my Samsungs TVs not into standby mode. Not even when TV is set to turn-off on loss of signal. I have no idea which signaling this is, maybe it works for other screens.

Koenn was reporting on github that it works with him, but no idea whether he is using TV or HDMI->DVI converter and and PC/LCD panel. There was one more issue with this and that XBMC wasn't able to get re-attached to the screen again, so restart xbmc was needed. Ugly.

the scripting around XBMC's actual status is already implemented in XBian. package name is "xbian-package-upstart-xbmc-bridge". it generates various upstart events - among others screensaver START and screensaver STOP. included in the package is xbmc-screensaver upstart job which uses this to standby / power-on CEC TVs based on those events and xbmc-priority job which utilizes the other statuses (Playing video, Updating library, idling, etc …).

based on those 'templates', write own script is peace of cake. actually the core code just 5 lines as upstart_job.conf file + 2 lines of command user wishes to run.

@f1vefour
the idle cpu usage is definitely addon and/or skin issue. default install XBian B2 is 14% on homescreen, up to 30% when idle in library view. this with Confluence or Amber skin - didn't try others.
