Exclusively on the AVC series, an operator may choose automatic transitions that are not linear, that is that do not have the same rate as they progress. One may choose logarithmic, starting rapidly and finishing slowly; exponential, starting slowly and finishing rapidly; or sinusoidal, starting and finishing slowly but fast in the middle.
Industry:Software
A video mixing architecture where a series of video multipliers, each combining two video signals, is cascaded or arranged in a serial fashion. The output of one multiplier feeds the input of the next, and so on, permitting effects to be built up, one on top of the other.

Systems Network Architecture entered the market in 1974 as a hierarchical, single-host network structure. Since then, SNA has developed steadily in two directions. The first direction involved tying together mainframes and unintelligent terminals in a master-to-slave relationship. The second direction transformed the SNA architecture to support a cooperative- processing environment, whereby remote terminals link up with mainframes as well as each other in a peer-to-peer relationship (termed Low Entry Networking (LEN) by IBM). LEN depends on the implementation of two protocols: Logical Unit 6.2, also known as APPC, and Physical Unit 2.1 which affords point-to-point connectivity between peer nodes without requiring host computer control. The SNA model is concerned with both logical and physical units. Logical units (LUs) serve as points of access by which users can use the network. LUs can be viewed as terminals that provide users access to application programs and other services on the network.
Physical units (PUs) like LUs are not defined within SNA architecture, but instead, are representations of the devices and communication links of the network.
Industry:Software
The smallest area of a television picture capable of being delineated by an electric signal passed through the system or part thereof. Note: It has three important properties, namely Pv, the vertical height of the picture element; Ph, the horizontal length of the picture element; and Pa, the aspect ratio of the picture element. In an analog system Pv = 1/N, where N is the number of active scanning lines in the raster, Ph = trA/tc, where tr is the average value of the rise and delay times (10% to 90%) of the most rapid transition that can pass through the system or part thereof, tc is the duration of the part of a scanning line that carries picture information, and A is the aspect ratio of the picture.
Industry:Software
Type of edit transition where either the video or audio of the source is delayed from being recorded for a given time.
Industry:Software
The duration of an automatic transition from one bus to the other is defined as the transition rate. The transition rate may be applied to a mix, wipe or E key, and is operator-selectable from 0 to 9.9 seconds.

The production cycle begins with the introduction of images in photographic, electronic imaging, or computational media. Image capture in real-time is usually essential for recording live subjects and maintaining the impact of realism. Image generation, normally achieved in nonrealtime, provides additional subject matter that can be edited into and combined with recorded live subjects to achieve programs that are more artistic, or more instructional, or both.
