Digital Teievision
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-Compatibte (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 PTV is capable of displaying only the 480p/480i SDTV signal using the
Panasonic DTV-STB, model TU-DST50 or TU-DST51. In order to view DTV
programming, the DTV-STB must be connected to TV component video inputs (Y, P
0,
P
r
) and audio inputs and in component 1 or 2 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.
