A keyer where two levels of hole cutting are independently adjustable. The top level, or insert, cuts a hole and fills with the key video. In a luminance key, the second level forms the border of the key; in a chroma key, the second level forms the shadow. The second level has adjustable luminance allowing borders to be varied from black to white and shadows to be varied in density. This is the type of keying provided on all Ampex switchers.

The thickness of the magnetic coating applied to the base film of a mag tape. Modern tape coatings range in thickness from 170 to 650 microinches. Coating thickness is normally optimized for the intended application. In general, thin coatings give good resolution at the expense of reduced output at long wavelengths; thick coatings give a high output at long wavelengths at the expense of degraded resolution.

A base-2 numbering system using the digits 0 and 1 (as opposed to 10 digits, 0-9 in the decimal system). In computer systems, the binary digits are represented by two different voltages or currents, one corresponding to 0 and the other corresponding to 1. All computer programs are executed in binary form. Binary representation requires a greater number of digits than the base-10 decimal system more commonly used. For example, the base-10 number 254 is 11111110 in binary. The result of a binary multiplication contains the sum of digits of the original numbers: in binary: 10101111 x 11010100 = 10010000011101100 in decimal: 175 x 212 = 37,100 From right to left, the digits represent 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768. Each digit is known as a bit. This example multiples two 8-bit numbers to produce a 16-bit result, a very common process in digital television equipment.

a) A transmission line with a concentric pair of signal carrying conductors. There is an inner conductor and an outer conductor metallic sheath. The sheath aids in preventing external radiation from affecting the signal on the inner conductor and minimizes signal radiation from the transmission line. b) A large cable composed of fine foil wires that is used to carry high bandwidth signals such as cable TV or cable modem data streams.

A 4-bit representation of the 10 decimal digits “0” through “9.” Six of the sixteen possible codes are unused. Two BDC digits are usually packed into one byte.

A type of coating used on magnetic recording tape. This is normally a gamma ferric oxide particle which has been doped with cobalt to achieve a higher coercivity. Modern forms of this oxide are acicular and have been used to make tapes with coercivities in excess of 1000 oersteds.
Industry:Entertainment
An executable file that contains a relocatable machine code program; in other words, a program ready to be run.
Industry:Entertainment
Interference caused by two or more television broadcast stations using the same transmission channel in different cities.
It is a form of interference that affects only broadcast television.
