A pure sub-band coder performs a set of filtering operations on an image to divide it into spectral components. Usually, the result of the analysis phase is a set of sub-images, each of which represents some region in spatial or spatio-temporal frequency space. For example, in a still image, there might be a small sub-image that represents the low-frequency components of the input picture that is directly viewable as either a minified or blurred copy of the original. To this are added successively higher spectral bands that contain the edge information necessary to reproduce the original sharpness of the original at successively larger scales. As with DCT coder, to which it is related, much of the image energy is concentrated in the lowest frequency band. For equal visual quality, each band need not be represented with the same signal-to-noise ratio; this is the basis for sub-band coder compression. In many coders, some bands are eliminated entirely, and others are often compressed with a vector or lattice quantizer. Succeedingly higher frequency bands are more coarsely quantized, analogous to the truncation of the high-frequency coefficients of the DCT. A sub-band decomposition can be the intraframe coder in a predictive loop, thus minimizing the basic distinctions between DCTbased hybrid coders and their alternatives.
Industry:Software
a) A serial to parallel and parallel to serial converter. b) A serial interface which serializes parallel data and inserts start, stop, and parity bits. It may also change a serial data stream into parallel bits or bytes and separate start, stop, and parity bits.
Industry:Software
A digital video interface which uses twisted pair wiring and 25-pin D connectors to convey the bits of a digital video signal in parallel.
There are various component and composite parallel digital video formats.
Industry:Software
Color intensity extracted from a “smooth” set of predetermined values varying from an initial to a final intensity.
Industry:Software
Special program that simulates the logical operation of the microprocessor. It is designed to execute machine language programs on a machine other than the one for which the program is written. This allows programs for one microprocessor to be debugged on a system that uses another processor.
Industry:Software
A chart with special patterns, placed in front of a television camera to generate a known reference signal that can be used to adjust the camera and all the equipment downstream from the camera.
Industry:Software
A computer language designed to control exactly how and where printed elements (lines, type, graphics) will appear on the page.
