A device used for measuring the intensity of an audio signal.
Industry:Software
The number of bits of colour information per pixel. A system using eight bits per pixel can display 256 (28) colors. A system using 16 bits per pixel can display 65,536 (216) colors. A system using 24 bits per pixel can display over 16.7 million colors. Twenty-four-bit colour is often called true colour because the human eye can distinguish among approximately six million different colors, or fewer than are available in a 24-bit colour system.
Industry:Software
The movement of the electron beam from the right-hand edge of the display to the left-hand edge or from bottom to top.
Retrace occurs during the blanking time. See Horizontal Retrace and Vertical Retrace.
Industry:Software
A half-resolution input signal used by MPEG-1. See Standard Input Format. This is also known as “Source Input Format” and “Standard Interchange Format.”
Industry:Software
The time sequence of the bits (DVB-S) is predefined by convolutional coding and, like the state diagram of a finite automaton, is represented as a trellis diagram.
Industry:Software
a) Schemes for compressing high bit rate signals to channels with much lower bit rates.
b) A reduction in the real-time transmission rate in digital format, usually to facilitate recording, transmission, broadcast, display, etc., or even to comply with fixed limitations.
Various algorithms appropriate for video signals may be applied from arbitrary sampling to more complex process with the objective of reducing the transmission of redundant information to the image and possibly eliminate image content that will not be obvious in the final specified display. Bit rate reduction is also appropriate and employed in audio records, either associated with video or standing alone.
Industry:Entertainment
Bit-rate reduction of an image signal by powerful algorithms that compress beyond what is achievable in lossless compression, or quasi-lossless compression. It accepts loss of information and introduction of artifacts which can be ignored as unimportant when viewed in direct comparison with the original. Advantage is taken of the subtended viewing angle for the intended display, perceptual characteristics of human vision, statistics of featured populations, and the objectives of display. The lost information cannot be regenerated from the compressed bit stream.
Industry:Entertainment
Either a perfectly square (9:9) aspect ratio or the field: frame ratio of progressive scanning.
