GLOSSARY Analog Audio DNS Server An electrical signal that directly represents sound. Compare this to digital audio which can be an electrical signal, but is an indirect representation of sound. See also “Digital Audio”. A server which translates Internet domain names into IP addresses. Dolby Digital Aspect Ratio The system to compress digital sound developed by Dolby Laboratories. It offers you sound of stereo (2ch) or multi- channel audio. The width of a TV screen relative to its height. Conventional TVs are 4:3 (in other words, the TV screen is almost square); widescreen models are 16:9 (the TV screen is almost twice as wide as it is high).
Dolby Digital Plus BD-Live Dolby Digital Plus is the next generation digital audio compression technology developed as an extension to Dolby Digital. Blu-ray Disc supports 7.1 multi-channel surround sound output. BD-Live is a BD-video (BD-ROM version 2 Profile 2.0) which contains new functions (e.g. Internet connection), in addition to the BONUSVIEW function. Dolby Pro Logic II Blu-ray Disc (BD) Dolby Pro Logic II technology processes any high quality stereo (two-channel) movie and music audio into five playback channels of full-bandwidth surround sound.
A matrix surround decoding technology, Dolby Pro Logic II detects the directional cues that occur naturally in stereo content and uses these elements to create a five-channel surround sound playback experience. Blu-ray Disc is a next generation optical video disc which is capable of storing much more data than a conventional DVD. The large capacity makes it possible to benefit from the features such as high-definition videos, multi-channel surround sounds, interactive menus and so on. Chapter Dolby TrueHD Just as a book is split up into several chapters, a title on a BD-video or DVD-video is usually divided into chapters. See also “Title”.
Dolby TrueHD is a lossless coding technology developed for next generation optical discs. Blu-ray Disc supports 7.1 multi-channel surround sound output. Component Video Output DTS® (Digital Theater System) Each signal of luminance (Y) and component (P B /C B , P R /C R ) is independent to output so that you can experience picture color as it is. Also, due to compatibility with progressive video (525p/ 480p), you can experience higher-density picture than that in interlace (525i/480i). DTS® is a multi channel surround sound system. You can enjoy movie dynamic and realistic sound like movie theater. DTS surround sound technologies were developed by DTS, Inc.
DTS-HD® DTS-HD® is a lossless coding technology developed as an extension of the original DTS Coherent Acoustics format. Blu-ray Disc supports 7.1 multi-channel surround sound output. Digital Audio An indirect representation of sound by numbers. During recording, the sound is measured at discrete intervals (44,100 times a second for CD audio) by an analog-to- digital converter, generating a stream of numbers. On playback, a digital-to-analog converter generates an analog signal based on these numbers. See also “Sampling Frequency” and “Analog Audio”. Gateway IP address of the electronic devices (such as router) which provide Internet access.
DivX® DivX® is a codec (compression/decompression) that can compress pictures to a very small amount of data. The software can compress video data from almost any devices to the size that can be sent on the Internet without compromising visual quality of the pictures. HDMI (High Definition Multimedia Interface) A digital interface between audio and video source. It can transmit component video, audio, and control signal with one cable connection. Hub A device used for connecting multiple device to the network. EN 62
