The PLUGE signal was designed for rapid and accurate adjustment of the black level, reference and, hence, the luminance range, display. It provides adjacent vertical bars, one at black level, reference and continuous bars slightly above and slightly below that reference. Following initial development by the BBC, CCIR now recognizes at least eight versions. SMPTE EG 1-1990 includes a variant in which the black level, reference is flanked by bars at –4 IRE and +4 IRE. When the –4 IRE merges into the black level, reference bar, but the +4 IRE bar is distinguishable, black level, reference is correctly set. A white patch is included at peak white, to define IRE 100, and the luminance range, display CRT.

The amount of resolvable detail in the horizontal direction in a picture. It is usually expressed as the number of distinct vertical lines, alternately black and white, which can be seen in three-quarters of the width of the picture. This information usually is derived by observation of the vertical wedge of a test pattern. A picture which is sharp and clear and shows small details has a good, or high resolution. If the picture is soft and blurred and small details are indistinct it has poor, or low resolution.
Horizontal resolution depends upon the high-frequency amplitude and phase response of the pickup equipment, the transmission medium and the picture monitor, as well as the size of the scanning spots.

A form of buckling in which the tape pack is deformed into a shape which approximates a polygon.
Industry:Software
Broadcast station that rebroadcasts signals of other stations without originating its own programming.

With orthogonal projection, parallel receding lines do not converge. The process of projecting from 3D to 2D is particularly simple, simply throw away the Z-value of each coordinate.
Industry:Software
Short for progressive scanning. A system of video scanning whereby lines of a picture are transmitted consecutively, such as in the computer world.

A storage system that provides audio and video storage for a network of clients. While there are some analog systems based on optical disks, most used in professional and broadcast applications are based on digital disk storage. Aside from those used for video on demand (VOD), video servers are applied in three areas of television operation: transmission, post production and news. Compared to general purpose file servers, video servers must handle far more data, files are larger and must be continuously delivered. There is no general specification for video servers and so the performance between models varies greatly according to storage capacity, number of channels, compression ratio, and degree of access to stored material, the latter having a profound influence. Store sizes are very large, typically up to 500 gigabytes or more. Operation depends entirely on connected devices, edit suites, automation systems, secondary servers, etc., so the effectiveness of the necessary remote control and video networking is vital to success.

The tag forms the most important part of a cache directory entry.
Using the tag, the cache controller determines whether a cache hit or miss occurs. The tag holds the address of the assigned cache line.
Industry:Software
Where all components of the video signal jitter (change in time) together in relation to another video signal.
