A waveform monitor display mode in which the Y and two chrominance components of an analog component video are shown side by side on the waveform screen.
Industry:Software
Technique used to facilitate the troubleshooting of digital circuits. Nodes of the circuit, stimulated during a test mode, produce “signatures” as the result of the data compression process performed by the signature analyzer. When a node signature is compared to a known good documented signature, faulty nodes can be identified.
Industry:Software
A type of scalability where an enhancement layer also uses predictions from pel data derived from a lower layer using motion vectors. The layers have identical frame rates size, and chroma formats, but can have different frame rates.

This is a name for the contrast or picture control. It describes a function that is otherwise not clearly spelled out in names of controls used on monitors. It is not a term found on a monitor control. (As “black level” clearly defines the brightness control function, “white level” more clearly defines the contrast or picture control function.) White Noise - A random signal having the same energy level at all frequencies (in contrast to pink noise which has constant power per octave band of frequency).
Industry:Software
a) Special effect in which the picture is reduced to a small number of colors or luminance levels removing any fine gradations of color and brightness resulting in an oil painting effect. Both the Video Equalizer and Digital Video Mixer includes this effect. b) An ADO special effect where a frame of video is broken down into flat areas of color. This mimics the silk screen printing method used by graphic designers to create poster designs, hence the derivations of the name.

Routers connect networks at OSI layer 3. Routers interpret packet contents according to specified protocol sets, serving to connect networks with the same protocols (DECnet to DECnet, TCP/IP (Transmission Control Protocol/Internet Protocol) to TCP/IP). Routers are protocol-dependent; therefore, one router is needed for each protocol used by the network.
Routers are also responsible for the determination of the best path for data packets by routing them around failed segments of the network.
Industry:Software
A term used to describe a picture condition in which objects appear to be extended horizontally beyond their normal boundaries. This will be more apparent at vertical edges of objects when there is a large transition from black to white or white to black. The change in luminance is carried beyond the transition, and may be either negative or positive. For example, if the tonal degradation is an opposite shade to the original figure, (white following black), the streaking is called negative; however, if the shade is the same as the original figure, (white following white), the streaking is called positive. Streaking is usually expressed as short, medium, or long streaking. Long streaking may extend to the right edge of the picture, and in extreme cases of low-frequency distortion, can extend over a whole line interval.
Industry:Software
A microphone which picks up signals primarily from one direction and discriminates against or rejects sounds arriving from other directions.
Industry:Software
A multi-conductor cable carrying simultaneous transmission of data bits. Analogous to the rows of a marching band passing a review point.
