A TV tuner is either an internal card—installed inside your computer like a video card—or external hardware that is connected to your computer's USB port. When you have a TV tuner that's designed for Windows Vista Home Premium or Windows Vista Ultimate, you can watch and record TV on your Windows Media Center PC by connecting to a TV signal and receiving the signal from an antenna or cable TV source. Some PCs that run Windows Vista Home Premium or Windows Vista Ultimate are sold with a TV tuner installed. If your PC didn't come with a TV tuner, you can add one at any time. With one TV tuner, you can: - Watch, pause, and rewind live TV on one channel
- Record TV on one channel
- Watch a show that you have previously recorded while you record another show
With two TV tuners, you can: - Watch live TV on one channel and record a show on a different channel
- Record two different TV shows that are on two different channels at the same time
- Watch a show that you have previously recorded while two shows are recording at the same time, on two different channels
To find the appropriate TV tuner and remote for your PC, you may also: Refer to the hardware documentation that came with your PC. Visit the hardware manufacturer's website. Contact the hardware manufacturer directly.
