DVD 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 singlesided DVD, at 4.7 GB (Giga Byte), is 7 times that of a CD. Furthermore, the data capacity of a dual-layer and single-sided DVD is 8.5 GB, a single-layer and double-sided DVD 9.4 GB, and a dual-layer and double-sided DVD 17 GB. The picture data uses the MPEG 2 format, one of a worldwide standard of digital compression technology. The picture data is compressed to about 1/40 of its original size. The DVD also uses the variable rate coding technology that processes allocated data 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. DVD+RW A DVD+RW (plus RW) is a recordable and rewritable disc. DVD+RWs use a recording format that is comparable to the DVD VIDEO format. DVD-RW 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. File A JPEG image recorded on a DATA CD/DATA DVD. ("File" is an exclusive definition for this system.) A single file consists of a single image. Film based software, Video based software DVDs can be classified as film based or Video based software. Film based DVDs contain the same images (24 frames per second) that are shown at movie theaters. Video based DVDs, 92US such as television dramas or sit-coms, displays images at 30 frames (or 60 fields) per second. HDMI (high-definition multimedia interface) HDMI is an interface that supports both video and audio on a single digital connection, allowing you to enjoy high quality digital picture and sound. The HDMI specification supports HDCP (high-bandwidth digital contents protection), a copy protection technology that incorporates coding technology for digital video signals. Interlace format (Interlaced scanning) The Interlace format is the NTSC standard method for displaying TV images at 30 frames per second. Each frame is scanned twice alternately between the even numbered scanning lines and then odd numbered scanning lines, at 60 times per second. Mica-reinforced-cellular-diaphragm The Mica-reinforced-cellular-diaphragm is made of a light weight and highly rigid composite material that consists of Mica flake and synthetic fiber. It is constructed with layers of Mica flake. This construction realizes diaphragm with low density and high rigidity at the same time. In this system, a Mica-reinforced-cellulardiaphragm is used for the subwoofer. MPEG audio A coding system to compress digital audio signals. MPEG-1 is used for MP3 (MPEG-1 Audio Layer-3). MPEG-2 is used for one of the audio format of DVD. Multi-angle function Various angles of a scene, or viewpoints of the video camera are recorded on some DVDs. Multilingual function Several languages for the sound or subtitles in a picture are recorded on some DVDs.
