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.

DIGA's original i/p conversion and up-conversion	Richer
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.

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.

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.

Significant motion Slight motion No motion

Diagonal Processing

This function detects where there are diagonal lines in an image such

as a building, and eliminates jaggies to make the lines smooth and razor sharp.

2:2 Detection and Processing

This function determines whether the playback source is a film or video. It then applies the most suitable type of i/p conversion accordingly.

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.
