2.3.12Separate audio masters, digital multichannel audio programs

For DVDs with digital multichannel sound, a separate audio mastertape is required for each soundtrack. These should be of either Sony PCM-3324 format, Sony PCM-800 format or equivalent and must contain the final mix of the 5.1 channels – front left, front right, left surround, right surround, centre low frequency channel – as discrete tracks. The encoding of these tracks to the specified digital multichannel datastream is carried out during the DVD premastering process.

2.3.12.1 General

Menus are the key to navigation on a DVD disc. They allow the user to locate any chapter point on the disc, change the language for the movie or display subtitles in any of the languages provided.

Basic menu structure:

Sony DCE has all the equipment and skills required to prepare menu screens from scratch or by using refer- ences such as existing artwork (e.g. LD or VHS packa- ging) for graphics, movie captures for animations, 3D modelling, Internet convergence, eCommerce integra- tion and other multimedia applications for DVD.

We therefore will readily accept your order to design the menu screens for you.

2.3.12.2

Backgrounds

 

When designing backgrounds, six major issues need to

 

be addressed. These are Image Size, Safe Area, Colour

 

Depth, Interlacing, File Format and Naming Convention.

 

2.3.12.3

Image Size

 

Computer pixels have an aspect ratio of 1:1. However,

 

NTSC pixels are 0.9:1 and PAL pixels are 1.0667:1. This

Video

discrepancy causes the menu background to look dis-

torted when exported to D-1 video; NTSC D-1 menus

are compressed horizontally and PAL D-1 menus are

compressed vertically. The menus should be distorted

at design time to counter the effects of TV distortion.

DVD

For NTSC the menus should be pre-compressed verti-

cally and for PAL, the menus should be pre-com-

pressed horizontically. To accomodate PAL and NTSC

requirements and to compensate for these known dis-

2.

tortions, the menus for NTSC should be designed

at 720x540 pixels and for PAL at 768x576 pixels. For NTSC, resize the image to a height of 480 pixels, keeping the width at 720 and for PAL, resize the image to a width of 720, keeping the height at 576. At this point the menus will look distorted on a computer screen, but this will be compensated for when they are exported to D-1 or DigiBeta.

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.
