Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
An electronic device that modifies and RF signal using an audio and/or video signal.
Industry:Software
A term sometimes applied to describe a fine herringbone pattern in a picture. May also cause a slight horizontal displacement of scanning lines resulting in a rough or ragged vertical edge of the picture.
Caused by high-frequency interference.
Industry:Software
Modulated composite (video and audio) signal produced by television stations and VCRs, and to be processed by televisions.
Industry:Software
A device that provides multiple RF signals. An RF splitter is used to send the signal from one VCR to two or more televisions.
Industry:Software
A) The basic parallel component analogue signal set (red, green, blue) in which a signal is used for each primary color. These three colour signals are generated by the camera and are used in the colour television’s additive colour reproduction system to produce a picture. Also used to refer to the related equipment, interconnect format or standards. The same signals may also be called “GBR” as a reminder of the mechanical sequence of connexions in the SMPTE interconnect standard.
b) A colour model used chiefly for computer displays in which colours are specified according to their red, green, and blue components. Compare YUV.
Industry:Software
A chroma key wherein the keying signal is derived from the separate red, green and blue camera video signals, as opposed to composite chroma key. It is an option to all switchers that allows chroma keys to be performed. See Chroma Key.
Industry:Software
There are four RGB formats. The main difference between them are in the voltage levels as shown below.

Industry:Software
The effective value of a wave. The value of continuous (direct current) signal that would produce the same power as the wave in question.
Industry:Software
A 16-byte long error control code added to every 187 (scrambled) +1 syncbyte-long transport packet with the following result. The packet has a length of 204 bytes and the decoder can correct up to T = 8 errored bytes. This code ensures a residual error bit rate of approximately 1x10–11 at an input error rate of 2x10–4.
Industry:Software
Now called EIA-170A, this is the EIA NTSC Video Signal specification standard.
