Introduction
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.
Composite video – A single video signal that contains luminance, color, and synchronization
information. NTSC and PAL are examples of composite video systems.

– The logo representing Dolby Digital.
Dolby Digital – A perceptual coding system for audio, developed by Dolby Laboratories and
accepted as an international standard. Dolby Digital is the most common means of encoding
multi-channel audio.
– The logo representing DTS.
DTS – A type of multi-channel surround sound format used on discs.
DVD – An acronym that is most commonly known to mean Digital Video Disc or Digital Versa-
tile 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 – A video format which has black borders at the top and bottom of the picture.
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 U.S. organization that
developed both the American Black & White and Color television systems.
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 – 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.
S-video – A video interface standard that carries separate luminance and chrominance sig-
nals, usually on a four-pin mini-DIN connector. Also called Y/C. The quality of S-video is sig-
nificantly better than composite video since it does not require a comb filter to separate the
signals. Most high-end televisions have S-video inputs.

Videostage
5 decoding circuitry – Proprietary Bose invention which gives you a five-chan-
nel surround sound experience from everything you listen to – VHS tapes, stereo CDs, even
mono TV programs.
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.
