Title number
Title numbers refer to titles of movies etc. As DVD discs have a
large capacity, many movies can be recorded on one disc. For
example, when 3 different movies are recorded on a disc, they
are divided into TITLE 1, TITLE 2 and TITLE 3. Playback can be
operated by selecting the title number.
Legato Link conversion
Although signal frequencies recorded on the discs are limited to
no higher than 20KHz, because there are frequency components
included in the sound of nature and musical instruments that
exceedthis, it’s not really accurate to say that discs are recorded
with the actual original signal wave forms. Legato Link conversion
is technology that supposes what the original signal was before
it was recorded on the disc in order to realize sound reproduction
that is very close to the original sound.
Chapter number
Chapter numbers are the numbers assigned to sections of a title
on the disc, similar to chapters in a book. If the disc includes
these numbers, you can locate the section you want very quickly
using chapter search and other functions.
Time number
The time number is the playback lapse time of a title in the disc
from its beginning. The scene you want to locate can be searched
for with the time number using the time number function etc..
TOC
TOC (Table Of Contents) information is data other than audio signal
data, recorded at the beginning of a disc. As the name implies,
it’s like the list of contents in a book, with information such as the
number of songs and playback time.
