In particular, an instruction at the end of a subroutine that causes control to resume at the proper point in the main routine.
Industry:Software
The ratio of transmitted power to reflected power in transmission lines, antenna systems, connectors, etc.
Industry:Software
Slang term for the button on the video camera or camcorder that, when depressed, sends a signal to the videotape recorder to begin or stop recording.
Industry:Software
A) Picture element with equal vertical and horizontal sample spacing, having an aspect ratio of 1:1. Square pixels are used by computers, and the software expects the use of square pixels for proper operation.
Video originally was unconcerned about the aspect ratio of its pixels.
Increasing dependence upon electronic post-production has emphasised the advantage of square pixels. b) System M/NTSC, by comparison, does not have square pixels. With 485 active vertical lines per frame, and 768 samples per active horizontal line (when sampled at four times subcarrier) in a 4:3 aspect ratio, the resulting pixels have an aspect ratio (width:height) of 0.842. c) During image processing, some transforms that manipulate individual pixels as independent picture elements - especially those operations involving any image rotation, distortion, or size changes are performed with simplified programmes and less risk of artefacts when the pixels are square.
Industry:Software
A measure of the similarity of the impedance of a transmission line and impedance at its termination. It is a ratio, expressed in dB, of the power of the outgoing signal to the power of the signal reflected back from an impedance discontinuity.

SRI International owns DSRC, developer of the ACTV schemes.
Industry:Software
A) To add or subtract from and EDK time or switcher sequence duration. b) To perform some minor adjustment or X, Y, or Z axis on ADO or switcher effects.
Industry:Software
In display terms, the pixel colour information is stored in four bits across four memory planes. This allows a maximum of 16 colours (24). See Packed Pixel.
Industry:Software
The persistence of a sound after the source stops emitting it, caused by many discrete echoes arriving at the ear so closely spaced in time that the ear cannot separate them.
Industry:Software
32-bit codes embedded in that coded bit stream that are unique. They are used for several purposes including identifying some of the structures in the coding syntax. Start codes consist of a 24-bit prefix (0x000001) and an 8-bit stream_id.
