Digital Television
Digital Television (DTV) broadcasts are available in at least 10 major U.S. markets.
Broadcasts will be in both high definition (HDTV) and standard definition (SDTV). The
HDTV signal formats are 1080i (interlaced scan) and 720p (progressive scan). SDTV
signal formats are 480i and 480p.
HDTV-Compatible
(1080i/720p)
HDTV-compatible
TV models process and display the high definition output from a
DTV Set-top Box (STB) at 1080i (interlaced) or 720p (progressive) lines. When 1080i
or 720p HDTV is available in your viewing area, your TV will be compatible when
using a Panasonic DTV-STB, model TU-DST50 or TU-DST51.
SDTV-Compatible
(480p/480i)
SDTV-compatible
TV models process and display the standard definition output with
the use of a Panasonic DTV-STB at 480 lines, interlaced or progressive scan. When
DTV programming is available, you can view it in the standard format, 4:3 aspect
ratio.
DTV Compatibility
of PT-56WXF95
This TV is capable of displaying
both 1080i and 720p HDTV signals as well as
the 480p/480i
SDTV signals using a Panasonic DTV-STB, model TU-DST50
or
TU-DST51.
In order to view DTV programming, the STB must be connected to the TV
by component video (Y, PB, PR)and audio inputs. A DTV signal must be available in
your area and the DTV-STB must be tuned to the proper channel.
Color Matrix Adjustment
When viewing DTV programming from a DTV-STB, this TV automatically adjusts the
color parameters for 1080i, 720p and 480p transmissions.
However, when viewing a
nonstandard DTV signal format, you can change the color parameters manually in the
Roller Guide PICTURE Menu for best picture quality.
Progressive
Scan
Progressive scan de-interlaces the incoming 480i signal and progressively scans the
image. This allows you to sit very close to the TV and not see the thin black horizontal
scan lines (venetian blind effect) associated with an interlaced picture.
