ATSC Tuner
An ATSC (Advanced Television Systems Committee) tuner, often called an ATSC receiver or HDTV tuner is a type of television tuner that allows reception of digital television (DTV) television channels transmitted by television stations in North America, parts of Central America and South Korea that use ATSC standards. Such tuners may be integrated into a television set, VCR, digital video recorder (DVR), or set-top box that provides audio/video output connectors of various types.
Another type of television tuner is a digital television adapter (DTA) with an analog passthrough.
