text:
Ghost-canceling reference (GCR) is a special sub-signal on a television channel that receivers can use to compensate for the ghosting effect of a television signal distorted by multipath propagation between transmitter and receiver. In the United States, the GCR signal is a chirp in frequency of the modulating signal from 0 Hz to 4.2 MHz, transmitted during the vertical blanking interval over one video line, shifted in phase by 180° once per frame, with this pattern inverted every four lines.
