Clear QAM TV channels are unencrypted digital TV channels broadcast by your local cable operator. Many cable operators in North America are transmitting the high definition ATSC channels on their cable networks. They also broadcast the basic cable channels in using clear QAM. You can use the WinTV v6 application to watch and record these channels. Note: currently Media Center cannot be used for clear QAM digital TV.
ATSC digital TV is the over-the-air HD digital TV for North America. ATSC digital TV typically requires an antenna for reception, and is currently broadcast in 200 cities, with over 1500 TV stations. ATSC broadcasts range in resolution from standard definition up to the high definition 1080i format. The WinTV-HVR can be used to watch and record all ATSC formats. Note: ATSC digital TV is NOT digital cable TV or digital satellite TV. ATSC is digital "over-the-air" TV.
ATSC digital TV brings you sharper pictures and enriches your PCs multimedia experience with near CD quality sound. WinTV-HVRs ATSC digital TV tuner adds great features to your TV viewing: high definition TV reception, automatic identification of channel names plus records high-definition digital TV programs to your PCs hard disk in an MPEG-2 format without any loss in quality.
