The BT848 Tweaked Philips WDM TVTuner C2 (NTSC) driver is associated with a TV tuner card that uses the BT848 chipset, which is commonly found in older TV tuner cards. The BT848 chipset was produced by Brooktree (later acquired by AVerMedia) and was widely used in various video capture and TV tuner devices in the late 1990s and early 2000s. The Philips WDM in the name refers to the Windows Driver Model (WDM) driver interface, which was the standard for video capture cards at the time.

The NTSC in the driver name indicates that the card is designed for the NTSC television standard, which is used in regions like the United States, Canada, and Japan.
