Pan&Scan/Letterbox

In general, DVD-Video are produced with the intention that they be viewed on a widescreen television with an aspect ratio of 16:9. This means you can view most mater- ial with the intended aspect ratio on a widescreen television.

Material with this ratio will not fit onto a stan- dard television with an aspect ratio of 4:3. Two styles of picture, “Pan&Scan” and “Letterbox”, deal with this problem.

Pan&Scan: The sides are cut off so the pic- ture fills the screen.

Letterbox: Black bands appear at the top and bottom of the picture so the picture itself appears in an as- pect ratio of 16:9.

Playback control (PBC)

If a Video CD has playback control, you can select scenes and information with menus (called menu play in these instructions).

Play list

This is a collection of scenes. It enables you to play these scenes in succession or to se- lect specific ones to play.

Program

This is a division on DVD-RAM.

Sampling rate

This is the number of samples of sound taken per second during conversion to a digital signal. Sampling frequency is ex- pressed in kilohertz (kHz). A high sampling frequency results in a sound close to the original when played back.

Title/Chapter

DVD-Video are divided up into large sections, titles, and smaller sections, chapters. The numbers allocated to these sections are called title numbers and chapter numbers.

Track

This is the smallest division on DVD-Audio, CD, and Video CD, and usually equates to a single song.
