A TV tuner card is a computer component that allows a computer to receive and decode television signals. This can be useful for watching live TV, recording TV shows, or using a computer as a home theater PC.
TV tuner cards come in a variety of form factors, including PCI, PCIe, and USB. The type of form factor you need will depend on the available expansion slots on your computer’s motherboard. TV tuner cards also come with a variety of features, such as support for different TV standards (ATSC, DVB-T, etc.), picture-in-picture, and electronic program guides. Depending on your needs, you’ll need to consider which features are important to you.
