Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
A) The immediate switching from one video source to another during the vertical blanking interval. The visual effect is an abrupt change from one picture to another.
b) The nearly instantaneous switch from one picture to another at the on-air output of the switcher. The switcher circuitry allows cuts only during the vertical interval of the video signal so as to prevent disruption of the picture. On the Vista, the Cut push-button in the Effects Transition control group activates an effects cut. The DSK Cut Key-In pushbutton cuts the downstream key on or off air. On AVCs, this is performed by a zero time auto transition.

A) Video that forms a background scene into which a key may be inserted. Background video comes from the Preset Background and/or programme Background bus or from an N/E “A” or “B” bus.
b) A solid-color video output generated by the colour Background generator within the switcher for use as background video.

That frequency beyond which no appreciable energy is transmitted. It may refer to either an upper or lower limit of a frequency band.
Industry:Entertainment
In television, the circuits (usually satellite or telephone) used to transmit or “haul” a signal back from a remote site (such as a sports stadium) to a network headquarters, TV station, or other central location for processing before being distributed.

When a test signal having defined chrominance and luminance components is applied to the sending end of a television facility, chrominance-luminance delay inequality appears (at the receiving end) as the change in relative timing of the chrominance component relative to the luminance component of the test signal.
Industry:Entertainment
The circuit board that other boards in a system plug into.
Usually contains the system buses. Sometimes called a Motherboard.
Industry:Entertainment
When a test signal having defined chrominance and luminance components is applied to the sending end of a television facility, chrominance-luminance gain inequality appears (at the receiving end) as the change in amplitude of the colour component relative to the luminance component (of the test signal).
Industry:Entertainment
Transition limited to on/off or instantaneous transition-type edits; a basic editing process with limited capabilities.
Industry:Entertainment
Timing of a programme from the end to the beginning. A reversal of clock-order so that remaining time or time left to the end of the programme can be easily seen.
Industry:Entertainment
This distortion is present if chrominance gain is affected by chrominance amplitude. Chrominance nonlinear gain distortion is expressed in IRE or percent. It should be measured at different APL (Average Picture Level) and typically the worst error is quoted. Picture effects include incorrect colour saturation due to nonlinear gain in relatively high amplitude chrominance signals. The modulated pedestal test signal is used to test for this distortion.
