Aspect Ratio - The relationship of an image's horizontal length and vertical height. The horizontal length number is placed first (i.e. 3:2).
AV Control Center - This component contains the TV tuners and input switching for Hitachi's two-piece Plasma televisions. A single cable connects the AV Control Center to the display, thus eliminating wire clutter and the need for noisy internal cooling fans. In addition, because the pickup for the remote control is located in the display, the AV Control Center and all other home theater components can be placed out of sight - even behind closed doors.
Resolution - A measure of how closely packed the dots in a bitmapped image are, often expressed in dots per inch (dpi) or lines per inch (lpi). The higher the number, the higher the quality. However, doubling the resolution of an image results in a computer file four times as large, requiring more hard disk space and computer memory to handle the higher quality image. Resolution is also used to describe how close together a computer printer can print dots in an image. Again, the larger the number, the higher the quality. It is important to know the capability of the printer's resolution before scanning an image in order to get enough information to print the best quality.
Clipping Distortion - With the clipping distortion feature, the peaks of the output wave are "clipped" off, avoiding distortion that results from driving an amplifier beyond its limit.
FireWire - Apple's trademarked name for the IEEE 1394 external bus standard. This is an extremely fast computer port that can be used to connect up to 63 devices. FireWire supports isochronous data, meaning that it can deliver data at a guaranteed rate. Other trademarked names for the IEEE 1394 standard include i.link and Lynx.
PDA - personal digital assistant. A generic term which could apply to Pocket PCs with Windows CE or Palm OS devices.
S-video - Also called Y/C, this two-wire standard keeps the color separate from the intensity signal, and thus avoids the overlapping sideband problem of composite signals. (Converting an NTSC signal to S-video gains you nothing since what was lost cannot be recreated.) - Although the quality of S-video is close to component video, S-video cannot transport anything better than 480i.
