Watch HDTV on your computers, not just on your TV
How many devices do you have in your house that are capable of displaying high-definition content but have no way of getting high-definition content? If you have an HD television you can use your TV’s tuner (or external cable/satellite box) to tune the HD signal. But what if you also have a computer? Or two? Or three? Those devices are probably also capable of displaying HD content but have no easy way of actually receiving HD content. So how do you get that HD content to each of them without having to buy a separate HDTV tuner card for each PC?
