Glossary
Chapter (page 33)
Sections of a picture or a music feature that are smaller than titles. A title is composed of
several chapters. Depending on the disc, no chapters may be recorded.
Dolby Digital (page 46 and 51)
Digital audio compression technology developed by Dolby Laboratories. This technology
conforms to 5.1-channel surround sound. The rear channel is stereo and there is a discrete
subwoofer channel in this format. Dolby Digital provides the same 5.1 discrete channels of
high quality digital audio found in Dolby Digital cinema audio systems. Good channel
separation is realized because all of the channel data are recorded discretely and little
deterioration is realized because all channel data processing is digital.
Dolby Surround (Pro Logic) (page 46)
Audio signal processing technology that Dolby Laboratories developed for surround sound.
When the input signal contains a surround component, the Pro Logic process outputs the front,
center and rear signals. The rear channel is monaural.
Digital audio compression technology that Digital Theater Systems, Inc. developed. This
technology conforms to 5.1-channel surround sound. The rear channel is stereo and there is a
discrete subwoofer channel in this format. DTS provides the same 5.1 discrete channels of high
quality digital audio.
Good channel separation is realized because all of the channel data is recorded discretely and
little deterioration is realized because all channel data processing is digital.
DVD (page 8)
A disc that contains up to 8 hours of moving pictures even though its diameter is the same as a
CD.
The data capacity of a single-layer and single-sided DVD is 4.7 GB (Giga Byte), which is 7
times that of a CD. The data capacity of a double-layer and single-sided DVD is 8.5 GB, a
single-layer and double-sided DVD is 9.4 GB, and double-layer and double-sided DVD is
17GB.
The picture data uses the MPEG 2 format, one of the worldwide standards of digital
compression technology. The picture data is compressed to about 1/40 (average) of its original
size. The DVD also uses a variable rate coding technology that changes the data to be allocated
according to the status of the picture. Audio information is recorded in a multi-channel format,
such as Dolby Digital, allowing you to enjoy a more real audio presence.
Furthermore, various advanced functions such as the multi-angle, multilingual, and Parental
Control functions are provided with the DVD.
DVD-RW (page 8)
A DVD-RW is a recordable and rewritable disc that is the same size as a DVD VIDEO. The
DVD-RW has two different modes: VR mode and Video mode. DVD-RWs created in Video
mode have the same format as a DVD VIDEO, while discs created in VR (Video Recording)
mode allow the contents to be programmed or edited.
