In video, distortion usually refers to changes in the luminance or chrominance portions of a signal. It may contort the picture and produce improper contrast, faulty luminance levels, twisted images, erroneous colors, and snow. In audio, distortion refers to any undesired changes in the waveform of a signal caused by the introduction of spurious elements. The most common audio distortions are harmonic distortion, intermodulation distortion, crossover distortion, transient distortion, and phase distortion.
Industry:Entertainment
A) The process of getting a television signal from point to point; also the process of getting a television signal from the point at which it was last processed to the viewer. See also Contribution. b) The delivery of a completed programme to distribution-nodes for emission/transmission as an electrical waveform, or transportation as a physical package, to the intended audiences. Preparation for distribution is the last step of the production cycle. Typical distribution-nodes include: release and duplicating laboratories, satellite systems, theatrical exchanges, television networks and groups, cable systems, tape and film libraries, advertising and programme agencies, educational systems, government services administration, etc.
Industry:Entertainment
Device used to multiply (fan-out) a video signal.
Typically, distribution amplifiers are used in duplication studios where many tape copies must be generated from one source or in multiple display setups where many monitors must carry the same picture, etc. May also include cable equalisation and/or delay.
Industry:Entertainment
The level of quality of a television signal from the station to its viewers. Also know as Emission Quality.
Industry:Entertainment
A) Typically a random, low-level signal (oscillation) which maybe added to an analogue signal prior to sampling. Often consists of white noise of one quantizing level peak-to-peak amplitude. b) The process of representing a colour by mixing dots of closely related colors.
Industry:Entertainment
A slight expansion of the analogue signal levels so that the signal comes in contact with more quantizing levels. The results are smoother transitions. This is done by adding white noise (which is at the amplitude of one quantizing level) to the analogue signal prior to sampling.
Industry:Entertainment
A) A high capacity data tape format. b) A high-density tape storage medium (usually 10-20 gigabytes) used to transport and input data to master a DVD. Media is designated as “Type III” or “Type IV” for tapes used for DVD.
Industry:Entertainment
Originally, a MAC (Multiplexed analogue Component) with audio and data frequency multiplexed after modulation, currently a term used in Europe to describe a family of B-MAC-like signals, one of which is the British choice for DBS. See also MAC.
