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.
Technically speaking: WinTV-HVR-2250 is a PCI Express X1 board
based on the NXP 7164 bus interface chip. The WinTV-HVR-2250 contains
two tuners with a built-in TV splitter. There is one cable TV or TV
antenna connector which is split, providing a video source for both
tuners. For ATSC and QAM digital TV, all 18 ATSC formats including
1080i can be watched or recorded to disk as a MPEG-2 Program Stream.
The NXP 7164 contains two highly integrated MPEG-1/2 hardware encoders
for recording analog cable TV to disk. The playback of the recorded
ATSC and QAM digital TV and MPEG-2 encoded analog programs are done
through a software MPEG-2 player.
