Refers to video signal comprised of three kinds of signals combined: an image signal made up of luminance and chrominance signals using the frequency multiplication technique; burst signal providing the basis for colour reproduction; and synchronization signal.
8Component video signalA video signal system where parts of information necessary for reproducing image signal comprised of the three primary colours of light are transmitted via separate signal lines. Types of signal, such as R/G/B, Y/PB/PR, etc., are available.
8Disc menuA screen display prepared for allowing selection of images, sounds, subtitles, multiangles, etc. recorded on a DVD disc.
8Dolby DigitalA
Internal stereo mix of multichannel surround audio by a DVD player. The
A Digital Surround audio encoding format configured with six (5.1) channels, similar to Dolby Digital. It requires a decoder, either in the player or in an external receiver. DTS stands for Digital Theater Systems.
Not all DTS discs contain six (5.1) channels of information.8Interlaced scanIn the conventional video system, a picture is shown on the display monitor in two halves. The Interlaced scan system places lines of the second half of the picture
A
A method of displaying wide images like movies in the centre of a 4:3 TV screen with no part of the image deleted, by placing black bands on the top and bottom of the screen. This name has resulted from the screen form looking literally like a letter box.
8Linear PCM (PCM: Pulse Code Modulation)A system for converting analog sound signal to digital signal for later processing, with no data compression used in conversion.
8MP3A file format with a sound data compression system. “MP3” is the abbreviation of Motion Picture Experts Group 1 (or
A family of Standards for compressing
By recording multiple scenes progressing at the same time in a single title, the user can select view angles. This feature is called the multiangle function.
8MultichannelDVD is specified to have each sound track constitute one sound field. Multichannel refers to a structure of sound tracks having three or more channels.
8MultilanguageWhen a title is created to cope with multiple languages, it is generally called a multilanguage title.
8NTSC (National television system committee)A black and white and colour television system format used in the U.S.A., Canada, Mexico and Japan.

Refers to the signal recorded on Video CD/SVCDs for controlling reproduction. By using menu screens recorded on a Video CD/ SVCD that supports PBC, you can enjoy
Progressive scan displays all the horizontal lines of a picture at one time, as a single frame. This system can convert the interlaced video from DVD into progressive format for connection to a progressive display. It dramatically increases the vertical resolution.
8Region CodeA system for allowing discs to be played back only in the regions designated beforehand. All the countries in the world are grouped into six regions, each region being identified by a specified Region Code (or region number). If the Region Code given to a disc includes a numeral which matches one in the Region Code of a player, the player can play back the disc.
8Sampling frequencyFrequency of sampling data when analog data is converted to digital data. Sampling frequency numerically represents how many times the original analog signal is sampled per second.
8SurroundAsystem for creating
The rate of transferring digital data. Usually the measure is in baud per second. The DVD system applies a variable transfer rate system for high efficiency.
