a) A commonly used term for a component digital video format.
The details of the format are specified in the CCIR-601 standard document.
The numerals 4:2:2 denote the ratio of the sampling frequencies of the single luminance channel to the two color difference channels. For every four luminance samples, there are two samples of each color difference channel.
b) ITU-R BT.601 digital component waveform sampling standard where the luminance signal is sampled at the rate of 13.5 MHz, and each of the color difference signals, (Cr and Cb) are sampled at the rate of 6.25 MHz each. This results in four samples of the luminance signal for each two samples of the color difference signals. See ITU-R BT.601-2.
Industry:Entertainment
Device that forms, as output, the sum of two or more numbers presented as inputs.
Industry:Entertainment
A sampling ratio that has equal amounts of the luminance and both chrominance channels.
Industry:Entertainment
Any material in the coating of magnetic tape other than the oxide and the binder resins; for example, plasticizers (materials used to soften an otherwise hard or brittle binder), lubricants (materials used to lower the coefficient of friction of an otherwise high-friction binder), fungicides (materials used to prevent fungus growth), dispersants (to uniformly distribute the oxide particles), or dyes.
Industry:Entertainment
A connector used in audio production that is characterized by its single shaft with locking tip.
Industry:Entertainment
Color specification system in which primary colors are added together to create a desired color. An example is the red/green/blue (RGB) system. Additive systems are generally associated with light emitting devices (CRTs).
Industry:Entertainment
A mix wherein the instantaneous video output signal is equal to the weighted sum of the input video signals. Unless otherwise specified, “mix” is taken to mean “additive mix.”
Industry:Entertainment
Field rate of some European proposals for a world standard of ATV (Advanced Television).
