Refers to the most minute elements in a picture which are distinct and recognizable. Similar to Definition or Resolution.
Industry:Entertainment
Microcomputer system with all the facilities required for hardware and software development for a given microprocessor.
Generally consists of a microcomputer system, CRT display, printer, mass storage (usually dual floppy-disk drivers), PROM programmer, and incircuit emulator.
Industry:Entertainment
Software to enable a computer to access or control a peripheral device, such as a printer.

Amount of detail that can be perceived in a diagonal direction. Although diagonal resolution is a consequence of horizontal and vertical resolution, it is not automatically equivalent to them. In fact, ordinary television systems usually provide about 40 percent more diagonal resolution than horizontal or vertical. Many ATV schemes intentionally sacrifice diagonal resolution in favour of some other characteristics (such as improved horizontal or vertical resolution) on the theory that human vision is less sensitive to diagonal resolution than to horizontal or vertical. There is some evidence that diagonal resolution could be reduced to about 40 percent less than either horizontal or vertical (overall half of its NTSC value) with no perceptible impairment. See also Resolution.

An unusual quad split feature found on Ampex switchers, allowing diagonal or X-shaped divisions between sources, as opposed to the traditional horizontal and vertical divisions.

The dialogue normalisation value is a Dolby Digital parameter that describes the long-term average dialogue level of the associated program. It may also describe the long-term average level of programmes that do not contain dialog, such as music. This level is specified on an absolute scale ranging from –1 dBFS to –31 dBFS. Dolby Digital decoders attenuate programmes based on the dialogue normalisation value in order to achieve uniform playback level.
Industry:Entertainment
A file format that represents bitmap images in a device-independent manner. Bitmaps can be represented at 1, 4, and 8 bits-per-pixel with a palette containing colours representing 24 bits. Bitmaps can also be represented at 24 bits-per-pixel without a palette in a run-length encoded format.
Industry:Entertainment
Special effects created using a digital video effects (DVE) unit.

A) This nonlinear distortion is often referred to as “diff gain” or “dG.” It is present if a signal’s chrominance gain is affected by luminance levels. This amplitude distortion is a result of the system’s inability to uniformly process the high-frequency chrominance signals at all luminance levels. The amount of differential gain distortion is expressed in percent. Since both attenuation and peaking of chrominance can occur in the same signal, it is important to specify whether the maximum over all amplitude difference or the maximum deviation from the blanking level amplitude is being quoted. In general, the NTSC measurement standard defines differential gain as the largest amplitude deviation between any two levels, expressed as a percent of the largest chrominance amplitude. When differential gain is present, colour saturation has an unwarranted dependence on luminance level. colour saturation is often improperly reproduced at high luminance levels. The Modulated Ramp or Modulated Stair Step signals can be used to test for differential gain. b) The amplitude change, usually of the 3.6 MHz colour subcarrier, introduced by the overall circuit, measured in dB or percent, as the subcarrier is varied from blanking to white level.
