With Windows Media Center—a feature included in Windows Vista Home Premium and Windows Vista Ultimate—you can watch and record live TV on your computer. All you need is a TV tuner and a TV signal.
The following sections describe the kinds of tuners and signals that are available, and what you'll need to connect a TV signal properly. For information about setting up your TV signal to work with Windows Media Center, see Set up a TV signal in Windows Media Center.
A TV tuner is a device that enables you to connect an analog or digital TV signal to your computer. Without a TV tuner, you cannot watch and record live TV in Windows 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.
Most computers do not include a TV tuner, but in many cases, it is possible to add one. For information about compatible TV tuners, contact your computer manufacturer or go to the Windows Vista Hardware Compatibility List website.
You might even be able to add multiple tuners (for example, two individual tuners, one dual tuner, or one combo tuner) to your computer. Multiple tuners enable you to record one channel while watching another or to record two shows simultaneously. For more information about adding multiple tuners, see What should I know before adding TV tuners?
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.
For a list of supported signal types, see TV signals that are supported by Windows Media Center.
Before you can watch and record TV in Windows Media Center for the first time, you'll need to physically connect a TV signal to the TV tuner on your computer. This typically involves connecting one end of a coaxial cable to your tuner and the other end to your TV signal source (for example, an over-the-air antenna, a cable TV jack in the wall, a cable TV set-top box, or a satellite TV set-top box).
Windows Media Center supports both standard-definition TV signals and High Definition Television (HDTV) signals. Use the following tables to determine what you'll need to get your TV signal up and running.
