Through use of the MPEG audio specification, the ISDN (Integrated Services Digital Network) may be tuned into an audio transmission media. Data compression techniques like MPEG Layer II allow a tailored mix of cost and quality, and are now thought of implicitly when talking audio on ISDN.

The CCETT is one of the three licensors of the MPEG Layer II coding algorithm. The audio coding technique, originally developed for DAB under EUREKA 147 jointly with IRT and Philips, was selected by ISO/MPEG as Layer II of the MPEG-1 standard.

A seemingly impossible concept calling for channel- compatible ATV transmission of 850 lines of both static and dynamic horizontal and vertical resolution, among other characteristics. Its feasibility is being studied at ATRP.
Industry:Entertainment
A system for determining the tristimulus values of any spectral power distribution using the set of reference color stimuli X, Y, Z, and the three CIE color matching functions x(lambda), y(lambda), z(lambda), adopted by the CIE in 1931.
Industry:Entertainment
Three-dimensional, approximately uniform color space produced by plotting in rectangular coordinates L*, a*, b* quantities defined by the following equations. X, Y, Z describe the color stimulus considered, and Xn, Yn, Zn describe a specified white achromatic stimulus (i.e., white reference). Equal distances in the color space represent approximately equal color differences.
: L* = 116 (Y/Yn)^(1/3) – 16 Y/Yn a* = 500 ((X/Xn^(1/3) – (Y/Yn)^(1/3)) X/Xn ) > 0.008 856 b* = 200 ((Y/Yn)^(1/3) – (Z/Zn)^(1/3)) Z/Zn

Three-dimensional, approximately uniform color space produced by plotting in rectangular coordinated L*, u*, v* quantities defined by the following equations. Y, u', v' describe the color stimulus considered, and Yn, u'n, v'n describe a specified white achromatic stimulus (white reference). The coordinates of the associated chromaticity diagram are u' and v'. L* is the approximate correlation of lightness, u* and v* are used to calculate an approximate correlate of chroma. Equal distances in the color space represent approximately equal color differences.
: L* = 116 (Y/Yn)^(1/3) – 16 Y/Yn > 0.008 856 u* = 13 L * (u' – u'n) v* = 13 L * (v' – v'n)
Industry:Entertainment
A video system used in many commercial installations for specific purposes such as security, medical, and educational.
Industry:Entertainment
A group of pictures in which the last pictures do not need data from the next GOP for bidirectional coding. Closed GOP is used to make a splice point in a bit stream.
