Reference

Pan&Scan/Letterbox

In general, DVD-Video are produced with the intention that they be

viewed on a widescreen television (16:9 aspect ratio), so images

often don’t fit regular (4:3 aspect ratio) televisions. Two styles of

picture, “Pan & Scan” and “Letterbox”, deal with this problem.

Playback control (PBC)

If a Video CD has playback control, you can select scenes and

information with menus.

(This unit is compatible with version 2.0 and 1.1.)

Progressive/Interlace

The PAL video signal standard has 576 (or 625) interlaced (i) scan

lines, whereas progressive scanning, called 576p (or 625p), uses

twice the number of scan lines. For the NTSC standard, these are

called 480i (or 525i) and 480p (or 525p) respectively.

Using progressive output, you can enjoy the high-resolution video

recorded on media such as DVD-Video.

Your television must be compatible to enjoy progressive video.

Panasonic televisions with 576 (625)/50i · 50p, 480 (525)/60i · 60p

input terminals are progressive compatible.

Protection

You can prevent accidental deletion by setting writing protection or

deletion protection.

RGB

This refers to the three primary colours of light, red (R), green (G),

and blue (B) and also the method of producing video that uses them.

By dividing the video signal into the three colours for transmission,

noise is reduced for even higher quality images.

Sampling frequency

Sampling is the process of converting the heights of sound wave

(analog signal) samples taken at set periods into digits (digital

encoding). Sampling frequency is the number of samples taken per

second, so larger numbers mean more faithful reproduction of the

original sound.

Thumbnail

This refers to a miniature representation of a picture used to display

multiple pictures in the form of a list.

WMA ([EH69] [EH59])

WMA is a compression format developed by Microsoft Corporation.

It achieves the same sound quality as MP3 with a file size that is

smaller than that of MP3.

1080i

In one high definition image, 1080 (1125) alternating scan lines pass

every 1/50th of a second to create an interlace image. Because

1080i (1125i) more than doubles current television broadcasts of

480i (525i), the detail is much clearer and creates a more realistic

and rich image.

1080p

In one high definition image, 1080 (1125) scan lines pass at the

same time every 1/50

of a second to create a progressive image.

Since progressive video does not alternate scan lines like interlace,

there is a minimal amount of screen flicker.

720p

In one high definition image, 720 (750) scan lines pass at the same

time every 1/50

of a second to create a progressive image. Since

progressive video does not alternate scan lines like interlace, there

is a minimal amount of screen flicker.

Pan & Scan: The sides are cut off so the picture

fills the screen.

Letterbox: Black bands appear at the top and

bottom of the picture so the picture

itself appears in an aspect ratio of

16:9.
