A TV tuner is a device you can use to connect an analog or digital TV signal to your computer. Without a TV tuner, you can't watch and record live TV in Media Center. TV tuners come in two basic model types: external TV tuners, which usually plug into a USB port on your computer, and internal TV tuner cards, which you must install inside your computer.
With Windows Media Center you can watch and record live TV on your computer. All you need is a TV tuner and a TV signal.
Windows Media Center supports a wide range of TV signal types, including antenna signals, cable TV signals, and satellite TV signals. The type of signal you can set up is determined by the type of TV tuner you have installed on your computer, the area in which you live, and the cable or satellite television provider you subscribe to.
