Accurate and fast adaptation to a new programme run if time changes occur in the schedule.

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 minimising the basic distinctions between DCTbased hybrid coders and their alternatives.

A) A serial to parallel and parallel to serial converter. b) A serial interface which serialises 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.

Rough edit decision list made by screening original materials, but without actually performing edits.
Industry:Software
A horizontal line in the vertical interval that is sometimes used to evaluate the amount of noise introduced in a certain part of the transmission path. A line is reinserted (and is therefore relatively noise free) at one end of the transmission path of interest. This ensures that any noise measured on that line at the other end was introduced in that part of the path.
Industry:Software
Four-digit value generated by a signature analyzer, which is used to characterise data activity present on a logic node during a specific period of time.
Industry:Software
The finest moments of time that can be perceived in a particular system. It is not the same as dynamic resolution, which is spatial resolution when an image is changing. As an example, suppose a spoked wheel is turning. If the spokes are a blur when the wheel is not turning, the system has poor static resolution; if they are clear, it has good static resolution (for the spokes). If they are a blur when the wheel is turning, the system has poor dynamic resolution and poor temporal resolution.
If they are clear when the wheel is turning, the system has good dynamic resolution. If, though clear, they appear to be stationary, or turning in the wrong direction, or turning at the wrong speed, or flashing rapidly in different positions so it is impossible to tell which way or at what speed they are turning (a temporal blur), the system has poor temporal resolution. A great deal of evidence indicates that the human visual system cannot simultaneously perceive high spatial resolution and high temporal resolution.

A computer language designed to control exactly how and where printed elements (lines, type, graphics) will appear on the page.

This amounts to about 90% of the total picture area.
It is symmetrically located inside of the picture border. Home sets are overscanned.
The entire picture isn’t seen, the edges being lost beyond the border of the screen. Safe action area is designated as the area of the picture that is “safe” to put action that the viewer needs to see.
