Conventional chrominance-to-luminance gain and delay measurements are based on analysis of the baseline of a modulated 12.5T pulse. This pulse is made up of a sine-squared luminance pulse and a chrominance packet with a sine-squared envelope as shown in the figure below. This waveform has many advantages. First it allows for the evaluation of both gain and delay differences with a single signal. It also eliminates the need to separately establish a low-frequency amplitude reference with a white bar.
Since a low-frequency reference pulse is present along with the highfrequency information, the amplitude of the pulse itself can be normalized.
The HAD of 12.5T was chosen in order to occupy the chrominance bandwidth of NTSC as fully as possible and to produce a pulse with sufficient sensitivity to delay distortion.

This term refers to the kind of dimensionality (i.e., 2D, 3D) that can be created using multiplane animation.
Since a layer in such animation can lie in front of one cel (or plane), or in back of another layer, the resulting effect is of a three dimensional world. This is a limited 3D world, however, because the layers are fixed in relation to each other. For this reason, multiplane animation is referred to as 2-1/2 dimensions. It is a very useful technique, however, even for computer graphics, because by ordering the layers in the way a painter does, you can save the computer the need to compare objects that are in different layers (that is, compare them for purposes of hidden surface removal).

International standard for motion picture film shooting and projection, though film shot for television in 625 scanningline countries is usually shot at 25 frames per second (even if not, it is transferred to television at 25 frames per second). There are moves afoot in the U.S. to increase the film frame rate to 30 for improved temporal resolution.
The ImageVision HDEP system and other electronic cinematography systems use 24 frames per second. RCA once proposed an electronic cinematography system with 2625 scanning lines (2475 active), a 2:33:1 aspect ratio, and a frame rate of 23.976023 frames/sec.
Industry:Entertainment
Frame rate of television in all countries not conforming to CCIR system M (NTSC). Also the frame rate of film shot for television in those countries.
Industry:Entertainment
Frame rate of NTSC colour television, changed from 30 so that the colour subcarrier could be interleaved between both the horizontal line frequency and the sound carrier.
