A) Special effect in which the picture is reduced to a small number of colours or luminance levels removing any fine gradations of colour and brightness resulting in an oil painting effect. Both the Video equaliser 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.
Industry:Software
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
Term used for a type of camera movement, to swing from left to right across a scene or vice versa.
Industry:Software
Video: The color-difference signal(s) and the equation(s) for their derivation. colour Television: The sidebands of the modulated chrominance subcarrier that are added to the luminance signal to convey colour information.
Industry:Software
A signal format in which the signal matrix representing the picture contents consisting of the luminance and the two color-difference signals modulated on a colour subcarrier are digitised in the matrixed form as a single data stream. SMPTE 244M describes a digital composite television signal interface for 525-line/59.94 field/sec television systems. Specifications for digital magnetic video tape recording of composite digital video of 525-line or 625-line structure are grouped into the D2 VTR standards. For 525-line, sampled at 14.32 MHz, the specifications are SMPTE 245M, 246M, 247M, 248M, EG 20, and RP 155. An index to the specifications for D2 is SMPTE EG 22.
Industry:Software
Usually, but not always, referring to the accuracy of a screen display to show how the final result will look. For example, a word processor screen showing the final layout and typeface that will appear from the printer.
Industry:Software
A) All production work done after the raw video footage and audio elements have been captured. Editing, titling, special effects insertion, image enhancement, audio mixing, and other production work is done during post-production. Videonics equipment is ideally suited for use in post-production. b) The application of image processing to photographic or electronic recorded image information. Usually in addition to scene selection and simple scene transitions, rather complex processing may be proposed: montage of two or more images; integration of photographic and electronic image information; fitting and over-recording; changes of size, contrast, hue, or luminance; introduction of computer-generated components; simulated motion; creation of multi-layered composites with control of transparency. Audio information, maintained in synchronism with the images as specified by the script, is processed along with the image information.
