DVD responds to wide sized screens
From the beginning of its development, DVD was meant to be applicable for wide sizes.
When zoom reproduced (expanding the  mage in vertical and horizontal directions) on a
wide screen monitor, the picture quality isn’t weakened.  Instead, a beautiful and delicate
image is reproduced.

To use its large capacity equivalent to 7 times the time available on a CD in an effective way,
the 96kHz/24bit high sampling/high bit can record a dynamic range of 144dB super hi-fi digital
audio.  It also reproduces sounds beyond the range of human hearing, restoring subtle nuance
to original sounds.

1. Multi-Language Response
(1)
Sound Selection
DVD Video contains a maximum of 8 sound streams.  They flow together like traffic a
digital signal road.  Do not confuse this with “8 channels”.
Including the original language, a maximum of 8 different languages can be recorded.
Additionally, Dolby AC-3, 5.1ch can be included on all 8 streams.
For example, it is possible to put English sound 5.1ch on the first, French sound 5.1ch on
the second and non-compressed linear PCM on the third stream.
However, it requires an amount of data, so the recording time of images will be shortened.
To make the image recording time longer, there are options, such as occupying less streams,
and using 2 Dolby AC-3 channels instead of non-compressed linear PCM.
(2)
Subtitle Selection
Using the maximum 32 channel sub-image, DVD can process subtitles in a maximum of
32 languages.
Each language can be individually recorded on each channel, such as Japanese, English,
French, etc.

Multi-Story Function
If there are a number of subplots or side stories to a show, you can change its flow by
choosing story developments beforehand, or by pulling the menu at each divergence in the
story to choose your favorite stories.
A. Main story and side story function
By selecting stories, it is possible to reproduce not only the main story but a sub story
that develops as a supporting role, just by choosing one.
B. Multi-Version Function
It is possible to edit and reproduce a mixture of different versions, such as a theater
version, a complete version and a director’s cut version, without causing any breaks in
the story.

 How to Reproduce a Multi-Story
These multi-stories can be reproduced only on discs with the recordings of a multiple
number of stories that respond to each specification.
DVD discs respond to each situation’s specification.  Its recorded content and methods are
determined by what is on the disc.  Therefore, it is possible
that discs with various contents will be sold on the market.  Because of this factor, we cannot
now explain certain operating methods.
The following are the expected reproduction methods for multi-stories
1 Packaging of a DVD disc that contains a reproduction method
2 Choosing actions through the menu
3 Operation methods that will be shown every time they are needed, and having the
viewer follows the direction(s)
3. Multi Aspect Function
With its multi-aspect function, DVD discs can be used with any type of TV.
The “Squeeze System”, that compresses wide picture into the standard 4:3 ratio, will reproduce
the picture in full horizontal length on a wide screen TV, so there is no deterioration in the picture
quality.  For big image  projectors and normal TVs (4:3), a high quality picture can be reproduced
with the letter box, which shrinks vertical direction, or by pan & scan, which shows a 4:3 ratio
picture while cutting out the rest of the original image.
A majority of traditional “wide sized pictures” have been shown with black parts across the top
and bottom of 4:3 ratio screens.  Therefore, when these are projected on wide screened TV, they
are widened by magnifying the picture until the black part disappears.
In such a case, the lines of resolution on the black parts were removed, reducing the lines from
425 to 360.  That causes inferior picture quality.
However, “Squeeze Recording System” enables wide screen picture
reproduction that does not sacrifice any of the lines of resolution.
 *However, it is entrusted to the production section of the DVD disc to choose which system
to use and whether the DVD is available for letter box, pan and scan.  Please note that all DVD
discs can do this function.
