Please note that there are technical restrictions for

seamless playback in the creation of multiple alter-

natives. For example, the playtime variation of the

different alternatives within one block is limited.

2.3.8 Parental Lock

DVD Video Discs can be coded with a number from

1-5. DVD Players can only playback DVDs with a code

number lower than the password protected code set on

the player.

2.3.9 Multiangle

Multiangle allows the creation of different viewing alter-

natives within the same contents of a title. Using this

feature the user can select between different camera

views ”on the fly”.

2.3.10 Aspect Ratio

The video source material may be either of 4:3 or 16:9

anamorphic aspect ratio. Please define the correspon-

ding parameter on the Mastertape Info.

To maintain the maximum vertical resolution, 16:9

anamorphic is preferred for widescreen sources.

However, the aspect ratio must be constant within one

title of a DVD, otherwise different titles will have to be

created on the disc.

2.3.11 Audio Masters

All audio masters must be recorded with 48kHz sam-

pling rate, Linear PCM according to AES/EBU standard.

The use of emphasis is not recommended. For Mono-,

Stereo- or encoded Dolby ProLogic programs the audio

tracks of the video mastertape should be used. As

these mastertapes contain four audio tracks, a max-

imum of four different versions in mono or two stereo

soundtracks can be provided with the videotape.

The video and audio parts of the mastertape must be

synchronised.

2. DVD-Video

2.3.4 Subtitels

Subtitle companies are usually capable of handling

subtitles in almost any language. They usually require a

VHS copy of the program master with VITC or LTC time

code and preferably with a visual TC at the top of the

picture as well as a script of the dialog or lyrics.

2.3.5 Still Pictures

Still pictures can be utilized as a background for menus

in full colour and full resolution, or as a still/slide show.

2.3.6 Regional Coding

Most DVD players imply a certain code, which

corresponds to one of the six defined regions where

they are sold. Such a code, or several codes, can be

applied to the discs. However, the number of both the

player and the disc must match in order to enable disc

playback.

If regional code ”0” is applied, this DVD can be played

on every DVD-Player – no matter which regional code is

adjusted.

2.3.7 Multibranching

The DVD offers the function of playing alternative

blocks with different contents within one title. Using this

feature, different versions of a movie can be created.

For example, it would be possible to create a movie

which consists of an identical main block and an end

block with two alternatives, enabling the user to choose

between a happy or perhaps a tearful end. In general, it

will be useful to set the changeover of such blocks mat-

ching chapter points, if chapter points exist.
