2.3.4Subtitels

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.

2.3.5Still Pictures

Still pictures can be utilized as a background for menus in full colour and full resolution, or as a still/slide show.

2.3.6Regional 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.

2.3.7Multibranching

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.

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.

2.3.8Parental 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.

2.3.9Multiangle

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”.

2.3.10Aspect 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.

2.3.11Audio 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.

DVD Rom/DVD Video specifications

Sony DVD-ROM/DVD Video technology has played a significant role in the evolution of home entertainment and data storage. Since its introduction in the late 1990s, this versatile format has enabled users to enjoy high-quality video and audio, making it a standard for movie distribution and video playback.

One of the main features of Sony DVD-ROM is its substantial storage capacity. A single-layer DVD can hold approximately 4.7 GB of data, which is significantly more than a standard CD, while dual-layer DVDs can store up to 8.5 GB. This increased capacity allows for higher-quality video content, including full-length movies, with multiple audio tracks and subtitles included.

In terms of video quality, DVD Video supports a resolution of up to 720x480 pixels, providing a clear and vibrant viewing experience. The technology utilizes advanced compression techniques, such as MPEG-2, to efficiently encode video files while maintaining high fidelity. This level of quality, coupled with the ability to offer surround sound formats like Dolby Digital and DTS, makes DVD a preferred choice for cinema-quality home viewing.

Another significant characteristic of Sony DVD technology is its robustness and durability. Compared to other media formats, DVDs are less susceptible to scratches and degradation, ensuring a longer lifespan for physical media. They also employ error correction technologies that help maintain data integrity, providing a reliable storage medium for both movies and computer files.

One of the innovative features of Sony's DVD technology is the menu and navigation system. Users can easily access different scenes, bonus content, and settings through an interactive graphic interface. This enhances the overall viewing experience, offering flexibility to skip chapters or access special features without hassle.

Sony has also embraced the evolution of DVD technology with the introduction of DVD-Audio and DVD-RAM formats. DVD-Audio provides superior audio quality, supporting multi-channel sound and higher sampling rates, catering to audiophiles. Additionally, DVD-RAM offers rewritable disk capabilities, making it suitable for data storage solutions that require frequent modifications.

In conclusion, Sony DVD-ROM/DVD Video technology has established itself as a cornerstone in digital media. With impressive storage capacity, superior video and audio quality, robust durability, and user-friendly navigation, it continues to influence the landscape of home entertainment. As technology progresses, understanding these characteristics becomes essential for consumers and content creators alike, ensuring they can make informed choices in a shifting digital era.
