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 |
|
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 |
|
|
|
|
| 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 | |
| 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 | |
| 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. |
