A USB TV Tuner driver is a software component that allows your computer to recognize and interface with a USB TV Tuner device. A USB TV Tuner is a hardware device that enables your computer to receive and display television broadcasts, either via over-the-air signals (using an antenna), cable, or satellite. It converts the analog or digital TV signals into a format that your computer can understand and display.
The Windows driver for a USB TV Tuner ensures that Windows can detect the device, install the appropriate communication protocols, and make it available for use with TV-watching software or applications, such as Windows Media Center, third-party TV applications (e.g., VLC, MediaPortal), or streaming services that support TV tuners.
