Important HP Media Center PC Updates 7
HDTV (High Definition Television) is the highest
quality DTV standard. HDTV provides increased
picture detail (720p, 1080i) with a widescreen 16:9
aspect ratio and higher quality audio such as surround
sound, on a display that supports digital TV.
NTSC (National Television Systems Committee) is
standard (analog) TV. Standard TV broadcasts an
image resolution of about 210,000 pixels and is
distributed today through antenna, cable, digital
cable, or satellite.
Connecting an ATSC (DTV) antenna
NOTE: Refer to the Start Here booklet for specific
instructions on connecting an ATSC antenna. The
ATSC connector on the back of the HP Media Center
PC is labeled DTV Ant.
You can attach an external roof UHF antenna to
connect the HP Media Center PC for watching DTV
channels.
You must purchase an indoor or outdoor antenna
separately. A UHF antenna will receive NTSC and
ATSC channels, depending on the quality of the
antenna, geographic location, and broadcast
reception strength.
You might have to reposition the antenna for best
reception. Position the antenna based on the following
general criteria:
• Higher is better than lower. The ideal position is
above the roofline.
• Closer to or facing the broadcast tower is better
than farther away or facing away from the
broadcast tower.
• Larger typically receives stronger signals than
smaller.
• Outdoor is better than indoor because there is less
interference.
Refer to http://www.antennaweb.org for more
information about:
• The channels available in your area. The channels
may be color-coded by zone. Match your antenna
to your zone.
• Selecting the kind of antenna you need, depending
on the channels you want to receive.
• What direction to point your antenna.
• Positioning an HDTV antenna for best reception.
TV signal source overview
You must have a TV signal connected to the HP Media
Center PC for proper operation. The connectors on the
back of the PC are Input 1, Input 2, and DTV Ant:
• For an NTSC cable TV box, digital cable box, or
satellite receiver: use Input 1 or Input 2 (select
models only).
• For an NTSC analog cable RF coaxial connector:
use TV/Cable Ant.
• For ATSC high definition DTV Ant connector: use
DTV connected to a UHF antenna.
For NTSC dual tuner configurations, both TV sources
must be of the same type: either cable TV, digital
cable TV, satellite TV, or antenna. The TV sources must
also have the same, identical channel line-up; for
example, if you are using two satellite TV sources,
they must provide the exact same channels.
All TV viewing and scheduling is provided through the
Guide, so both TV sources must have identical
television guides.
If you are using the TV/Cable Ant input connector on
a dual tuner card to connect an antenna or analog
cable, the dual tuner card has an internal cable that
connects the signal to both TV tuners inside of the PC.
