The bowtie test signal actually consists of three signals, each being fed to a different channel of the CAV system and is used to evaluate the relative amplitudes and relative timing on some CAV waveform monitors such as the WFM300A. The figure below shows the three waveforms in the parade mode. The first signal is a 500 kHz sinewave packet which is fed to video channel 1. The other two signals are identical 502 kHz. The three sinewave packets are generated to be precisely in phase at their centers. Because of their 2 kHz offset, the colour difference channels become increasingly out of phase with the luminance channel on either side of center. If the three signals are properly timed, their sum results in the bowtie waveform shown below.
Industry:Entertainment
An organisation established by Cox Enterprises and Tribune Broadcasting, which together own 14 television stations, 24 CATV systems, and two production companies. The CVC, which is open to other organizations, was created to support ATV research and is currently supporting Del Ray’s HD-NTSC system.
Industry:Entertainment
A slang term for a mail-order business for audio and video components. Box houses frequently offer little or no consumer support or equipment repair.
Industry:Entertainment
Translation programme that converts high-level programme instructions into a set of binary instructions (machine code) for execution. Each high-level language requires a compiler or an interpreter. A compiler translates the complete program, which is then executed.
Industry:Entertainment
The relative elongation of a specimen of magnetic tape or base film at the instant of breaking when it has been stretched at a given rate.
Industry:Entertainment
A written accounting of the shooting schedule and production resources.
Industry:Entertainment
Consists of two or more simple surfaces attached or connected together using specific operations.
Industry:Entertainment
A) A break in the smoothness of a curve. b) Software or hardware device that stops the programme and saves the current machine status, under user-specified conditions.
Industry:Entertainment
A) A matrix, block or single pel from one of the three matrices (luminance and two chrominance) that make up a picture. b) A television system in which chrominance and luminance are distributed separately; one of the signals of such a television system; or one of the signals that comprise an ATV system (e.g., the widescreen panels component).
