1080p Up-Conversion*
1080p Technology
Ordinary TV broadcasts and DVD discs provide SD images with
640 x 480 pixels or 720 x 576 pixels. Today's newest HDTVs, on
the other hand, can display images with 1920 x 1080 pixels.
HD Displays require high-quality image sources suitable for
their large screens. If the optimisation process for high-quality
images is inadequate, the picture can become blurry or grainy.

Up-Conversion
Creating an HD image from a non-HD source, it requires obtain as
much information as possible about each pixel in the original image.
In the up-conversion process, DIGA calculates eight pixels in the
horizontal direction and eight in the vertical direction at the same
time using a high-speed algorithm. The information obtained in this
process is used to create smooth, natural-looking, high-resolution
1080p images.
Intelligent i/p Conversion
DIGA uses Precision Pixel Generation technology in
combination with three advanced functions - Pixel-Based
Motion Adaptive, Diagonal Processing, and 2:2 Detection
and Processing - to apply the type of i/p conversion that
best suits the image.
Pixel-Based
Motion Adaptive
This function detects motion
in the image and classifies
it into one of four levels.
It then applies the type of
processing that's best suited
to the level of motion.
*1080p compatible TV required.
2X LP Horizontal Resolution (500 Lines)
Panasonic original technology enables LP mode recording with the same 500 lines (D1) of horizontal resolution as that in the SP and XP
modes, which is double the horizontal resolution compared to the 250 lines (1/2 D1) of conventional LP mode recording. Thanks to this,
you can enjoy viewing extended recordings (4 hours [single-sided DVD-RAM, DVD-R, DVD-RW, +R, +RW] /7 hours 10 minutes [double sided
DVD-RAM, DVD-R, DVD+R]) with exceptionally detailed images and twice the picture quality.
4x Natural Gradation
The 12-bit Analogue-to-Digital converter provides an extremely dense 4,096 steps of gradation. Compared to the 1,024 steps possible
with a regular 10-bit Analogue-to-Digital converter, this enables recording with four times as many smooth steps. The result is
faithful reproduction of the details in both the bright and dark parts of scenes, so that for the first time you can see everything there is
to see.
Progressive Scan (PAL/NTSC)
Panasonic DVD Recorders are equipped with a high-precision progressive video processor that handles 60-frame progressive scan
images* on NTSC discs and 50-frames progressive scan images on PAL. This lets you enjoy high-resolution progressive playback of
original DVD images. To enjoy a progressive scan picture, you must use a TV with progressive scan capabilities.
*To enjoy a progressive scan picture, a TV with progressive scan capabilities must be used.

DIGA's original i/p conversion and up-conversion
functions solve this problem. These functions
convert SD signal from DVD discs or DIGA's own
hard disk drive into 1080p signals that provide high-resolution
images. The conversion process boosts the amount of image
information by about 5 times, so pictures are clear and beautiful.
