NSV™ Noise Shaped Video. NSV™ is a new video format. It is designed to be easily streamed,
support any audio and video codec, and be usable on nearly any platform. Currently NSV™
utilizes MP3 for audio and VP3 for video.
NTSC National Television Standards Committee.The television standard for North America and parts
of South America having 525 lines/60 Hz (60 Hz refresh), two fields per frame and 30 frames
per second.Technically, NTSC is a color modulation scheme.To fully specify the color video
signal it should be referred to as (M) NTSC. NTSC is also commonly (though incorrectly) used
to refer to any 525/59.94 video system. See (M)NTSC.
Ohm The unit of electrical resistance, transmitting a current of 1 amp when subjected to a potential
difference of 1 volt.
PCM Pulse Code Modulation is a digital scheme for transmitting analogue data. PCM makes it
possible to digitize all forms of analogue data, including full-motion video, voices and music.
Phase The relative timing of one signal to another, usually expressed in degrees of shift.
Radio frequency (RF) A range of frequencies used for electromagnetic transmission (e.g. radio and TV).
RDS Radio Data System is a service that allows FM stations to send additional information. If you
are receiving an RDS station, RDS and the station name are displayed.
RGB Red, green and blue.The basic components of the colour television system.They are also the
primary colours of light in the 'additive colour process'.
RGBS The red, blue, and green chroma information in a video signal, with a separate channel for the
sync signal.
Satellite receiver A receiver designed for satellite reception system, which receives modulated signals from an
LNA (Low Noise Amplifier. ) or LNB (Low Noise Block Downconverter.) and converts them
into their original form suitable for direct presentation to the user.
Saturation The intensity of the color, or the extent to which a given color in any image is free from white.
The less white in a color, the truer the color, or the greater its saturation.
Surround Sound A system of audio reproduction that uses four or more speakers to simulate the full three-
dimensional effect of a live musical performance or cinematic environment. (See also 'Dolby
Pro-Logic
®
Surround Sound').
S-video A composite video signal separated into the luma ('Y' is for luma, or black and white
information; brightness) and the chroma ('C' is an abbreviation for chroma, or color
information).
Sync Synchronization. In video, sync is a means of controlling when things happen with respect to
other things.This is accomplished with timing pulses to insure that each step in a process
occurs at exactly the right time. For example, horizontal sync determines exactly when to begin
each horizontal line (sweep) of the electron beam.Vertical sync determines when to bring the
electron beam to the top left of the screen to start a new field.There are many other types of
sync in a video system. .Also called 'sync signal' or 'sync pulse'.
Test Tone Dolby Pro-Logic
®
Surround Sound receivers offer this feature to allow individual adjustment of
allchannels according to your listening (viewing) location and individual preference.To set the
balance, a test tone is sent to each channel in a repeating cycle.
Toggle To switch between alternate states. For example: between on and off.
Tuner Radio receiver.
UCD User Centered Design. A method for designing ease-of-use into the total user experience with
products.
VCR Generally defined as video cassette recorder.
Watt A unit of electrical power used to indicate the rate of energy produced or consumed by an
electrical device. One watt is one joule of energy per second.
