A corresponding colour is defined as the stimulus that, under some different condition of adaptation, evokes the same colour appearance as another stimulus when it was seen under the original state of adaptation. colour match, corresponding is a subjective judgment.
Industry:Entertainment
The portion of the composite video signal whose instantaneous amplitude makes the vertical and horizontal retrace invisible.

A) colour images are metameric matches when their spectrally different colour stimuli have identical tristimulus values.
The requirements for such a metameric match can be calculated for a specified viewing condition (and for viewing conditions other than those specified, the chromaticity will not be judged to correspond). b) The corresponding colour chosen for the metameric match will not provide a spectrophotometric match. In practical applications, spectrophotometric matches are of only academic interest, and metameric matches are sought.
c) colour match, metameric, resulting from calculations based upon colorimetry, produces a visual match as evaluated by the CIE description of human observers.

A technique proposed in some ATV schemes to increase the VBI (and, sometimes, decrease the HBI) to deal with wide aspect ratios. See also Burn.
Industry:Entertainment
Any of several means of specifying colours according to their individual components. See RGB, YUV.

The horizontal blanking interval is the time between the end of one horizontal scanning line and the beginning of the next. The vertical blanking interval is the time between the end of one video field and the beginning of the next. Blanking occurs when a monitor’s electron beam is positioned to start a new line or a new field. The blanking interval is used to instantaneously reduce the beam’s amplitude so that the return trace is invisible.

A) Refers to the 0 IRE level which exists before and after horizontal sync and during the vertical interval. This voltage level allows the electron beam to be turned off while it is being repositioned (retracing) across the face of the CRT into the position needed to start tracing the next visible line. b) The level of the front and back porches of the composite video signal. c) The level of a composite picture signal which separates the range containing picture information from the range containing synchronising information. Note: This term should be used for controls performing this function (IEEE 100).
Industry:Entertainment
A component of a digital video system that provides a means of establishing colours (foreground and background) using a colour lookup table to translate a limited set of pixel values into a range of displayable colours by converting the colours to RGB format.
Industry:Entertainment
A piece of black plastic attached to the front plastic panel of the Indigo chassis that covers either the top or middle drive slot.
The blanking panel is removed after installing a drive in the slot that it was covering.
Industry:Entertainment
The phase of the chroma signal as compared to the colour burst, is one of the factors that determines a video signal’s colour balance.
