Digital chroma keying differs from its analogue equivalent in that it can key uniquely from any one of the 16 million colours represented in the component digital domain. It is then possible to key from relatively subdued colors, rather than relying on highly saturated colours that can cause colour spill problems on the foreground. A high-quality digital chroma keyer examines each of the three components of the picture and generates a linear key for each. These are then combined into a composite linear key for the final keying operation. The use of three keys allows much greater subtlety of selection than does a chrominance-only key.

A) The process of turning an analogue signal into digital data.
b) To convert an image from hard copy (a photo) into digital data for display on a computer.
Industry:Entertainment
Component signals in which the values for each pixel are represented by a set of numbers.
Industry:Entertainment
A system that converts an analogue input to a digital format, such as analog-to-digital converters (ADC), touch tablets, and mice. The last two, for example, take a spatial measurement and present it to a computer as a digital representation.
Industry:Entertainment
Digital video using separate colour components, such as YCbCr or RGB. See ITU-R BT.601-2. Sometimes incorrectly referred to as D1.
Industry:Entertainment
The act of taking analogue audio and/or video and converting it to digital form. In 8-bit digital video there are 256 possible steps between maximum white and minimum black.
Industry:Entertainment
The digitised waveform of (M) NTSC or (B, D, G, H, I) PAL video signals, with specific digital values assigned to the sync, blank, and white levels. Sometimes incorrectly referred to as D2 or D3.
Industry:Entertainment
Time taken to record footage into a disk-based editing system, usually from a tape-based analogue system, but also from newer digital tape formats without direct digital connections.
Industry:Entertainment
A) A digital video recording device based on high-speed computer disc drives. Commonly used as a means to get video into and out from computers. b) A video recording device that uses a hard disc or optical disc drive mechanism. disc recorders offer quick access to recorded material.
