The PC-DTV Receiver is a device typically used to receive digital television (DTV) signals on a computer, allowing users to watch and record TV broadcasts. It can support various types of TV signals, such as over-the-air (OTA) broadcasts or cable TV (depending on the model). The PC-DTV Receiver Windows driver is the software that enables the operating system to communicate with and control the PC-DTV receiver hardware.

In most cases, the driver is necessary to enable proper functionality of the DTV receiver on Windows, including TV reception, video recording, and playback. The Windows driver ensures that the system can detect and use the receiver card or USB device, making it possible for TV viewing software to interact with it.
