With the Sony PlayStation 4 not having an infrared sensor, you couldn't control it with a standard remote control. So, if you wanted to watch a Blu-ray on it, you still had to have the game controller on hand. Sony is fixing this issue with the release of its official PlayStation 4 Universal Media Remote. This remote can control three other devices, such as your TV and receiver, via IR. The remote will be available later this month for US$29.99.
