A control monitor is one employed primarily for decisions on subject matter, composition, and sequences to be selected in realtime.
It is frequently one of several monitors mounted together in close proximity as in a studio: for example, to display multiple sources that are to be compared, selected, and combined in editing for immediate, direct routing to display. The physical arrangements may make it very difficult to control the surroundings for each monitor, as specified by SMPTE Working Group on Studio Monitors in Document S17.280 for the reference monitor.
It is nevertheless essential when sequences on several monitors are being compared and intercut that the monitors match in luminance and colorimetry.
Industry:Software
A small device incorporating the equivalent of hundreds or thousands of transistors, capacitors, resistors, and other components within a small, solid block.

A) The metric unit for illumination is 1 lumen per square meter.
1 foot candle = 10.76 Lux.
b) A measurement of light. Lux is used in television production to determine the minimum amount of light (lux rating) needed for camera operation. Hence, a “2 lux” camcorder requires less light than a “4 lux” camcorder.
Industry:Software
Relatively more levels of quantization are assigned to small amplitude signals, relatively fewer to the large signal peaks.

A reference monitor is one employed for decisions on image quality. Achieving controlled reproducibility for this application is the primary objective of the specifications for monitor standardization.
SMPTE Working Group on Studio Monitors, S17.28, has recognised the great disparity now existing among studio monitors and control monitors, and has noted the confusing variability among decisions based upon visual judgments of programme quality as evaluated on different monitors. They are working to identify and recommend specifications for the variables affecting subjective judgments, coming not only from the monitor capabilities, but also from the adjustment of its controls and the bias introduced by monitor surround and room illumination.
Industry:Software
A) A combined RF receiver and MPEG decoder that is used to adapt a TV set to digital transmissions. b) An IRD with digital interface has the ability to decode Partial Transport Streams (TS) received from a digital interface connected to digital bitstream storage device such as a digital VCR, in addition to providing the functionality of a Baseline IRD.
Industry:Software
The amount by which a measured video signal output differs from a standard video signal output. The greater this deviation, the greater the video signal distortion and possibility of luminance and chrominance problems. Having gain vary as a function of signal amplitude.
Industry:Software
Special circuitry is sometimes included in equipment to limit bandwidth or amplitude, i.e., white amplitude in cameras is generally limited.
Saturation of matte generators in switchers are generally limited to stop illegal colors.
Industry:Software
Although it is customary to make all subjective judgments of image quality from the reference monitor display, the infinite possibilities for monitor adjustments have hampered reviewers in exercising effective programme control, and have introduced many disparities and great confusion. The SMPTE Working Group on Studio Monitors, S17.27, is completing work on three specifications intended to make the monitor display follow a known transfer function, electro-optic, and permit a reliable evaluation of the programme image quality.
