The replacement for potentiometers on AVC switchers.
These allow three speeds of adjustment and may be assigned to any module. They offer a more compact package, and eliminate the problem of recalling an event that has different settings than the physical pots may have.

A PC port which receives or transmits data in byte or word form rather than bit form.

A) The process of beginning to read and decode the coded bit stream at an arbitrary point. b) Access method in which each word can be retrieved in the same amount of time (i.e., the memory locations can be accessed in any order).

Prior to the advent of multichannel television sound broadcasting, the only way to transmit a stereo television show to homes was by simultaneous broadcasting on TV and radio stations. Proponents of non-receiver compatible ATV schemes suggest the same technique to achieve compatibility with existing NTSC TV sets: The non-compatible ATV signal will be transmitted on one channel and a second channel will carry a standards-converted NTSC signal. It is sometimes suggested that such simulcast techniques of ATV transmission are more efficient than augmentation techniques since, when the penetration of ATV sets into households reaches some limit, the NTSC simulcast channel can be eliminated, conserving bandwidth. In Britain, an almost identical situation occurred when 625 scanning-line television replaced 405. For many years, all programming was simulcast in both line rates with 405 eventually eliminated.

These instruments provide a variety of known test and synchronisation signals for the characterization of television systems.

One of the three types of digital pictures in an MPEG data stream. A picture that is coded using motion compensated prediction from past reference pictures. The motion compensation is causal, that is, only based on preceding pictures, which can be I-pictures or P-pictures. This type of picture generally has more data than B-picture types.

A) In a digital video system, the sampling is quincunx if the luminance and color-difference samples are generated from pixels arranged on one of two congruent rectilinear grids, the one being displaced horizontally from the other by half the horizontal pixel spacing.
The alternate grid is usually chosen for alternate lines, but may instead be chosen for alternate field/frames. b) In a digital video system, a sampling structure with an array of samples wherein alternate rows of pixel samples are displaced horizontally in the grid by half of the pitch of the pixel samples along the remaining rows.
Industry:Software
Signal that has been sampled at a lower rate than some other signal in the system. A good example of this is the Y'CbCr colour space used in component serial video (ITU-R BT.601). For every two luma (Y') samples, only one Cb and Cr sample is taken causing the Cb and Cr signals to be subsampled.
