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 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, either 4:3
aspect ratio or 16;9 aspect ratio.
DTV Compatibility
This TV 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, Pg, 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.
