The structure of a video signal wherein the R', G', and B' signals are kept separate from one another or wherein luminance and two bandlimited color-difference signals are kept separate from one another.
Note: The separation may be achieved by separate channels, or by time-division multiplexing, or by a combination of both. [After SMPTE]

A profile that is made up of a defined subset of a single standard [POSIX.0].

A communications cable having both optical and metallic signal-carrying components.
Note 1: A cable having optical fiber(s) and a metallic component, e.g., a metallic twisted pair, used solely for conduction of electric power to repeaters, does qualify as a composite cable.
Note 2: A cable having optical fiber(s), plus a metallic strength member or armor, does not qualify as a… (Read More →)

The structure of a video signal wherein the luminance and two bandlimited color-difference signals are simultaneously present in the channel.
Note: The format may be achieved by frequency-division multiplexing, quadrature modulation, etc. It is common to strive for integrity by suitable separation of the frequencies, or since scanned video signals are highly periodic, by choosing frequencies such that the chrominance… (Read More →)

Signaling in which an arrangement is made to provide direct current signaling and dial pulsing beyond the range of conventional loop signaling.
Note: Composite signaling, like DX signaling, permits duplex operation, i.e., permits simultaneous two-way signaling. Synonym CX signaling.

A signal consisting of horizontal sync pulses, vertical sync pulses, and equalizing pulses only. [After Silicon]

In television systems, a test signal consisting of a line bar (125 ns rise time and fall time), a 2T pulse (250 ns half-amplitude duration), a
1
2. 5T (
1. 5625 microseconds half-amplitude duration) chrominance pulse, and a five-riser staircase signal modulated by the color subcarrier having a peak-to-peak amplitude of 40 IRE units superimposed upon standard synchronizing and… (Read More →)

A test signal composed of two different frequencies and used for intermodulation distortion measurements.

See composite video signal.

The electrical signal that represents complete color picture information and all synchronization signals, including blanking and the deflection synchronization signals to which the color synchronization signal is added in the appropriate time relationship. [After IEEE] Synonym composite video.
