Signal information recorded in the form of a modulated carrier.
Industry:Software
The act of storing switcher control panel data into memory in a real-time mode (learning as they happen).
Industry:Software
A test signal with five steps of luminance change, each step having a constant frequency and phase chrominance signal. This signal is used to test for Differential Phase distortions.
There is also a 10 step version of this signal.
Industry:Software
An algebraic metaphor for the amount of time a learner needs to learn a new task (such as operating an item of television production equipment).
Industry:Software
A test signal which consists of three chrominance packets with the same phase, on the same luminance level (50 IRE), with different amplitudes (20, 40, and 80 IRE). This signal is used to test for chrominance nonlinear phase distortion and chrominance to luminance intermodulation distortion.
Industry:Software
The bit that has the least value in a binary number or data byte. In written form, this would be the bit on the right. For example: Binary 1101 = Decimal 13 In this example, the rightmost binary digit, 1, is the least significant bit, here representing 1. If the LSB in this example were corrupt, the decimal would not be 13 but 12.
Industry:Software
A test signal with a linear rise in luminance and constant chrominance as shown in the figure below. This signal is used to test for Differential Phase distortions.
Industry:Software
Named for Bernard Lechner, researcher at RCA Laboratories. The Lechner distance is nine feet, the typical distance Americans sit from television sets, regardless of screen size. The Jackson distance, three meters, named for Richard Jackson, a researcher at Philips in Britain, is similar. There is reason to believe that the Lechner and Jackson distances are why HDTV research was undertaken sooner in Japan (where viewing distances are shorter) than elsewhere. See also Viewing Distance.
Industry:Software
a) The imposing of a signal on some type of transmission or storage medium, such as a radio carrier or magnetic tape. b) The process (or result) of changing information (audio, video, data, etc.) into information-carrying signals suitable for transmission and/or recording. In NTSC-M television transmission, video is modulated onto a picture carrier using amplitude modulation-virtual sideband, and audio is modulated onto a sound carrier using frequency modulation.
