Explanation of terms Interactive DVD This is the DVD disc whose story is changeable by user's selection, or whose direction of view is changeable. Title, chapter (DVD) DVD disc is divided into some large parts (title) and into some more small parts (chapter). Each part has a number which is called title number or chapter number. OPTICAL AUDIO OUT jack The OPTICAL AUDIO OUT jack changes electric signals into optical signals before transmitting them to the amplifier. According to this, the signals flow without electric effect from outside, noise are suppressed and give little effect for outside. Track (video CD/audio CD) A video CD or an audio CD is divided into some parts (track). Each part has a number which is called track number. Dolby digital (AC-3) This is the technique for digital audio compression developed by Dolby Corporation. Not only stereo (2 ch) sound but also 5.1 ch sound can be compressed by it. A large amount of data can be held in a disc efficiently. Dolby pro logic decoder This is the equipment in which 4 channel signals recorded in 2 channels by dolby surround (pro logic) are reverted to signals in 4 channels when playing them back. As compared with the surround sounds of 5.1 ch of dolby digital (AC3), separation between channels is worse and surround signal is played back only within 7 kHz. Pan & scan screen This signifies that the screen recorded in widescreen format is displayed with left and right portions cut off. Playback control (video CD) A video CD with the playback control function can be played back by following the menu display interactively. Letter box screen This signifies that the screen recorded in widescreen format is displayed with black bands at the top and bottom of the screen. Linear PCM audio (LPCM) This is the signal recording system for audio CD. While the signals are recorded by 44.1 kHz/16 bit in audio CD, by 48 kHz/16 bit - 96 kHz/24 bit in DVD. As a result, DVD is played back in higher quality sound than audio CD. MPEG (Moving Picture Experts Group) MPEG is the international standard format for moving pictures provided by Moving Picture Experts Group organized under ISO (International Organization for Standardization) and IEC (International Electro-technical Commission). MPEG provided MPEG1 in 1991, and MPEG2 in 1994. MPEG2 enables to play in higher quality than MPEG1.
