Digital Television
Digital Television
(DTV) broadcasts
are now available
in 10 major U.S. markets.
Broadcasts are 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.
SDTV-Compatible
(480p/480i)
SDTV-compatible
"IV 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, either 4:3
aspect ratio or 16:9 aspect ratio.
DTV Compatibility
This "IV is capable of displaying only the 480p/480i SDTV signal using the Panasonic
DTV-STB. In order to view DTV programming,
the STB must be connected to the TV
component video inputs (Y, PB, PR) and audio inputs and in DTV mode. A DTV signal
must be available in your area and the DTV-STB must be tuned to the proper channel.
Progressive
Scan
Progressive scan de-interlaces the incoming 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.
