LD terms
Chapter number
Just like the numbers assigned to chapters of a book, the
LD disc is divided into several chapters and each of them is
assigned a chapter number.
If the chapter numbers
are
recorded on the disc, it is possible
to perform
operations
such as the chapter search which quickly searches the de-
sired chapter.
•
Some LD discs do not contain recorded chapter num-
bers.
Frame number
A frame number is assigned to every frame on a CAV disc.
This makes possible operations
such as the frame search
which searches desired images based on their frame num-
bers.
Time number
This refers to the elapsed playing time from the beginning
of the disc that is recorded on CLV discs as well as on CAV
discs with a TOC*I.
This allows operations
such as the
time number search which searches desired images based
on their time numbers.

quickly searches the desired track.
TOC ('1)
CD and CDV discs contain non-audio information called TOC
the (Table Of Contents) at the beginning of the disc. As this
