The amount of undesirable harmonics present in an output audio signal expressed as a precentage. The lower the percentage the better.
TRACK AT ONCE (TAO)
A technology from SRS Laboratory that creates a broad, fully immersive sound image within the listening area that wraps around the listener's head regardless of seating position.
A loudspeaker driver designed to handle high frequency (treble) signals.
ULTRA EXTENDED GRAPHICS ARRAY (UXGA)
A UXGA display has 1600 horizontal pixels by 1200 vertical pixels, giving it a total display resolution of 1,920,000 individual pixels.
Allows connection via USB terminal to a PC and broadcast live video with audio, edit images, capture still images or play back recorded video scenes.
VARIABLE ATTENUATION CONTROL SYSTEM (VACS)
Continually monitors the balance between the current and voltage amplification stages in an amplifier, thereby reducing distortion even at high volume levels.
A mode that only scans the lines within the picture area when widescreen aspect ratio content is on the screen. This optimises picture quality by not utilising scan lines for the blank area at the top and bottom of the screen.
VIDEO GRAPHICS ARRAY (VGA)
A VGA display has 640 horizontal pixels by
480 vertical pixels, giving it a total display resolution of 307,200 individual pixels.
VIRTUAL MULTI DIMENSION (VMD)
Overcomes one of the fundamental challenges in accurately representing theatre sound in a confined space. Using 3D processing technology, it creates five pairs of "virtual" surround speakers from the existing rear speakers (or if unavailable the two front speakers). "Pitched" 25 to 35 degrees overhead, these virtual speakers create sound depth and scale, delivering a more realistic, spacious surround sound experience.
VIRTUAL PHONE TECHNOLOGY (VPT)
See Digital Signal Processing (DSP).
VOICE OPERATED RECORDING (VOR)
The standard unit of electric potential. It is defined as the amount of electrical potential between two points on a conductor carrying a current of 1 ampere while 1 watt of power is dissipated between the two points.
VOLUME UNIT (VU)
A unit of measurement of the power of an audio signal.
Unit of power. More watts mean more power, but how loud a system sounds also depends on speaker sensitivity and room size.
The ability of a camera to adjust the color balance of a picture to compensate for the ambient lighting.
WIDE BIT STREAM (WBS)
Conventional MiniDisc playback is done with
WIDE EXTENDED GRAPHICS ARRAY (WXGA)
A WXGA display has 1366 horizontal pixels by 768 vertical pixels, giving it a total display resolution of 1,049,088 individual pixels.
WIDESCREEN ASPECT RATIO
A range of picture aspect ratios that approximate that of 35/70mm film. Also known as 16:9.
•Anamorphic Widescreen: Squeezing and unsqueezing the video frame. 1.78:1 is squeezed into 1.33:1 frame. On a wide screen this screen can be expanded horizontally to form the complete resolution.
