Channels requires a source to stream your live TV from. It uses HDHomeRun network TV tuners to do this.
What the heck is an HDHomeRun? Put simply, its a TV tuner that provides it’s TV streams over your home network.
Channels uses it on your network to play those streams right in the app.
An HDHomeRun can use either free over-the-air HD television via your HD antenna, or your cable plan via a cable card provided by your operator.
Simply plug your HD antenna into your HDHomeRun instead of your TV and voila, all of your TV broadcasts are available in Channels.
HDHomeRun offers a model that uses cable cards, just like you might be familiar with on TiVo.
By plugging in the cable card provided by your operator, you’ll be able to utilize all of the channels you get with cable right in Channels.
