Reference signal used in video as the benchmark for hues.
A portion of the composite video signal used for decoding its color information. Burst is several c ycles of 3.58 MHz pulses recorded during the horizontal blanking interval and used to establish phase relationships for determining the hue. the color oscillator of a color television receiver is phase locked to the color burst.
Also called burst and burst flag. The segment of the horizontal blanking portion of the video signal that is used as a reference for decoding color information in the active video part of the signal. The color burst is required for synchronizing the phase of 3.58MHz oscillator in the television receiver for correct hues in the chrominance signal. In composite video, the image color is determined by the phase relationship of the color subcarrier to the color burst. The color burst sync is 8 to 11 cycles of 3.58MHz color subcarrier transmitted on the back porch of every horizontal pulse; The hue of the color sync phase is yellow-green.

sample of the color sub-carrier inserted into the horizontal blanking interval at the start of each line of video.
The portion of a composite video signal that comprises a few cycles of a sine wave of chrominance subcarrier frequency used to establish a reference for demodulating the chrominance signal.
That portion of the composite color signal, comprising a few cycles of a sine wave of chrominance subcarrier frequency, which is used to establish a reference for demodulating the chrominance signal.
The color burst, also commonly called the "color subcarrier," is 8 to 10 cycles of the color reference frequency. It is positioned between the rising edge of sync and the start of active video for a composite video signal.
The signal, at approximately 3.57MHz in the video bandwidth, that stores the instantaneous intensity and hue of the color for a particular spot in the TV image.
In NTSC color, normally refers to a burst of approximately 9 cycles of 3.6MHz subcarrier on the back porch of the composite video signal. This serves as a color-synchronizing signal to establish a frequency and phase reference for the chrominance signal.
