2.3.20Colour Depth

The highlight must be an indexed, 8 bit, 256 color TIFF file. Since DVD specifications allow 4 colours in a high- light at any given time, even though this file has 256 colors in its palette, the actual graphic can only have 4 colours. One of these colours is keyed out to show transparency. The remaining can be any three colours in the spectrum. The figure below is a screen shot of the palette of a highlight file. If you can’t access this option in your graphic program, the file is probably not indexed or has the wrong colour depth. Note that only the first 4 colours of the palette are in use and the remaining are blank. This is the only acceptable format of the highlight palette.

The DVD specification also allows any menu page to have a palette of 16 colours. This allows for different ”not highlighted state”, ”highlighted state” and ”acti- vated state” colours. The figure below shows two images, a ”highlighted state” and an ”activated state”.

Please note that the total number of colours (including black and the registration mark) is more than four. However, at any given time the image has only four colours.

Colour printouts of all backgrounds must be provided for reference. One printout should be provided to demonstrate the effect of the highlighted state and one to demonstrate the activated state. If these are diffe- rent for the Main Menu, Audio Menu, Subtitle Menu, Scene Selection Menus and Special Menus, then two printouts must be provided for every unique colour combination demonstrating both highlight and active colours.

A hard copy of the text or PDF files should also be pro- vided along with a printout of the disc contents.

2.3.21.2 Navigation

Non-standard navigation must be explained on paper and a text or PDF file. For complex navigation, it will be necessary to contact Sony SDCE.

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.
