BGR In fact TV's do have OS'es albeit primitive ones. They handle the user inputs(volumeUP, channelDown) by talking to the speaker controls and tuner module etc., handle putting up a menu on the screen and saving user settings(contrast etc.). All this requires some kind of a RTOS(I imagine) which provides services. The digital TVs is a whole new ballgame. They have to have a very sophisticated OS with pre-emptive multitasking, multithreading, communication protocol stack support, sophisticated memory management the works if they are going to do some fairly compute bound jobs(realtime decompression, managing aspect ratio etc.). I know a person working on this stuff and she assures me that its a nightmare!!!
