GLOSSARY

4:3 – See “Aspect ratio.”

5.1– channel surround sound – A movie recording technique that, when paired with a 5.1-channel home theater surround speaker system, surrounds the viewer with sounds from five different speakers for full-range sound and one speaker for low-frequency effects.

16:9 – See “Aspect ratio.”

AAnalog audio – Sounds that we hear with our ears are known as analog. Analog audio is data characterized by being continuously variable. Such data is usually stored as continuously varying physical undulations (vinyl albums) or as variations in a magnetic medium (tape). See Digital.

Aspect ratio – An expression for the width of the pic- ture relative to the height when seen as a rectangular TV image. For example, if the aspect ratio is 4:3 (read as 4 by 3), the shape of that picture is 4 units wide by 3 units high. The standard TV aspect ratios are 4:3 and 16:9.

CCD – The abbreviation for compact disc, a plastic-coated, metallized disc that stores digitally encoded music for high-quality playback when read by a laser beam in a compact disc player.

Chapter – A main division of contents in a DVD title.

Coaxial cable – Carries digital audio via a wire between a source device and your Lifestyle® system.

Component video – Also called YPbPr, this video sig- nal is split into three parts: luminance and two color sig- nals for considerably better resolution than can be provided by either composite or S-video signals. This more complex signal also requires the use of compo- nent connection jacks, which are not available on all televisions or video components.

Composite video – The simplest of three types of video signal, which combines rather than separates brightness (black and white) and color information. It provides the lowest resolution of the three, but is com- patible with the broadest range of televisions and other video components and requires a simple video cable connection to RCA jacks.
