HDMI CEC support

hi everyone, i was wondering if anyone knew of a way to allow hdmi cec passthrough while still using hyperion. I'm a complete newbie but I really hope this is possible in some way as otherwise I have spent my money for no reason. i really enjoy the fluidity of the apple tv being able to control my tv and I would prefer to keep it that way. if its possible please could you send some links as to where I can buy said capture cards or splitters. thank you!
