Introduction Chapter - In DVD-Video, a division of a title. Technically called a part of title (PTT). Component video - A video system containing three separate color component signals, either red/green/blue (RGB) or chroma/color difference (YPbPr), in analog or digital form. The MPEG-2 encoding system used by DVD is based on color-difference component digital video. Most televisions do not have component video inputs. Composite Video - A single video signal that contains luminance, color, and synchronization information. NTSC and PAL are examples of composite video systems. Dolby Digital 3/2.1 - A more technical representation of Dolby Digital 5.1 sound. The "3" represents the 3 front channels, and the "2.1" represents the 2 surround channels including a LFE (low-frequency effects) channel. DVD - An acronym that is most commonly known to mean Digital Video Disc or Digital Versatile Disc. The audio/video/data storage system is based on 12-cm optical discs. DVD Video - A standard for storing and reproducing audio and video on DVD-ROM discs, based on MPEG video, Dolby Digital and MPEG audio, and other proprietary data formats. IR - An acronym for infrared. Pertains to the type of remote that sends/receives commands on an infrared light beam. Letterbox - The projected aspect ratio of feature films is often wider than 525 or 625 line video formats. It is becoming common practice to transfer films to video with black borders at the top and bottom of the picture. The film picture becomes a "letterbox" within the video. MP3 - MPEG-1 Layer III audio. This is a compressed audio format that allows you to record many hours of music on a single CD. NTSC - An acronym for National Television System Committee. The organization that developed both the American Black & White and Color television system. PAL - An acronym for Phase Alternate Line. This is one of several composite video systems. The PAL format is used extensively in Western Europe. PCM - An uncompressed, digitally coded representation of an analog signal. This is the form of the digital audio signal used for both CD and laserdisc. It is a serial data stream that is coded for transmission or recording. PCM is also used for many other types of serial data communications. S-video - A video interface standard that carries separate luminance and chrominance signals, usually on a four-pin mini-DIN connector. Also called Y/C. The quality of S-video is significantly better than composite video since it does not require a comb filter to separate the signals. Most high-end televisions have S-video inputs. YPbPr - A component analog video signal containing one luminance and two chrominance components. Often referred to loosely as YUV or Y, B-Y, R-Y. 6 October 30, 2001 AM259776_01_V.pdf
