Actually, some phones have these functions. In 3rd world countries, TV reception is incredibly popular on cell phones. As to the IR led, the original galaxy s5 (not the new edition) comes with an IR and an app that helps configure frequencies for the remotes of different devices. I have an original s5 and can control almost any device that comes with a remote (tv, air conditioners, etc)... its awesome!
