Function

The TV tuner basically features a co-axial cable plug-in along with a computer connection in order to convert the picture from your cable line to your computer processor.

Types

There are two types of TV Tuners you can purchase. The first is for desktop computers and attaches right to the computer's motherboard. The second is a smaller USB tuner, specifically made for USB ports.

Accessories

Along with the TV tuner, some also come with RCA import plugs so you can capture video camera footage. Remotes are also included with the TV tuners.

Benefits

Newer TV Tuners allow HD reception and even if you do not own an HD television, most monitors can display HD content with just as good quality. You can also connect your video game console to the computer as well.

Prices

TV Tuners range in price depending on the quality and type. TV Tuners for mother boards range around $20 to $70 dollars while USB connections cost anywhere from $50 to $150 dollars.
