A) A rectilinear scanning process in which the distance from centre to centre of successively scanned lines is equal to the nominal line width. b) A display mode for electronic imaging in which all of the scanned lines are presented successively, and each field has the same number of lines as a frame. Also known as sequential scanning. For a given number of active vertical lines per frame, and a given frame rate, progressive scanning requires the same bandwidth as interlaced scanning.
When compared at a given field rate, progressive scanning requires twice the bandwidth of 2:1 interlaced scanning. Note: Most image processing in electronic post-production requires that a progressive scanned image first be captured or created. The image information may have originated in progressive scanning, or it may have been interpolated from an origination in interlaced scanning.
Industry:Software
General term for a device used to select different signals (audio, video, or RF) from various sources. See Video Switcher.
Industry:Software
A) The synchronising information which appears between fields. The vertical interval signals the picture monitor to go back to the top of the screen to begin another vertical scan. b) The portion of the video signal that occurs between the end of one field and the beginning of the next. During this time, the electron beams in the cameras and monitors are turned off so they can return from the bottom of the screen to the top to begin another scan.
Industry:Software
An electronic circuit which modifies basic patterns by rotating, moving positionally, adding specular effects to the borders, etc., thereby increasing the creative possibilities.
Industry:Software
Intel’s PC video capture card that can capture and even compress video in real-time, using Indeo technology.
Industry:Software
Information that is a direct function of time. An oscilloscope displays information in the time domain.
Industry:Software
A coiled cable with a loop for your wrist at one end and an alligator clip at the other. You fasten the clip to a metal part of the workstation and place the loop around your wrist whenever you work with internal components of the workstation to avoid electrical shocks to yourself and the components. See also Static Electricity.
Industry:Software
A row of crosspoint push-buttons used to select the video input that will be placed on-air during the next DSM background transition.
Industry:Software
A) The process of connecting and routing digital data on a network. b) The editing and splicing together of programme segments.
