DTS
Digital audio compression technology
developed by DTS, Inc. This technology
conforms to 5.1‑channel surround. The
surround channel is stereo and there
is discrete subwoofer channel in this
format. DTS provides the same 5.1
discrete channels of high quality digital
audio. The good channel separation is
realized because the all channel data
is recorded discrete and processed in
digital.

GB
DVD VIDEO
A disc that contains up to 8 hours of
moving pictures even though its diameter
is the same as an AUDIO CD. The data
capacity of a single‑layer and single‑
sided DVD VIDEO, at 4.7 GB (Giga
Byte), is 7 times that of an AUDIO CD.
Furthermore, the data capacity of a dual‑
layer and single‑sided DVD VIDEO is
8.5 GB, a single‑layer and double‑sided
DVD VIDEO 9.4 GB, and a dual‑layer
and double‑sided DVD VIDEO 17 GB.
The picture data uses the MPEG2 format,
one of the worldwide standards for digital
compression technology. The picture data
is compressed to about 1/40 of its original
size. The DVD VIDEO also uses variable
rate coding technology that changes the
data to be allocated according to the
status of the picture.
The audio data is recorded in Dolby
Digital as well as in PCM, allowing you to
enjoy more realistic audio presence.
Furthermore, various advanced functions
such as the multi‑angle, multilingual, and
Parental Control functions are provided
with the DVD VIDEO.
