Abstract
A component television timing corrector uses edge transitions in the program material of a television signal to determine the time differences between color component signals of the television signal due to the processing of the color component signals along different paths. One of the color component signal channels is made a reference channel, and the time differences between the edge transitions in the reference channel and in the other color component signal channels is determined. The time differences are used to delay the other two color component signal channels with respect to the reference color component signal channel so that the resulting color component signals are in time coincidence.
Claims10
A component television timing corrector comprising:
- means for determining for the program material content of a color television signal time differences between each color component signal of the color television signal and a reference timing signal, the color component signals being separately processed along different paths;
- and
- means for delaying each color component signal according to the time difference for that color component to provide delayed color component signals that are in time coincidence.
A component television timing corrector comprising:
- means for comparing the timing of one of a plurality of color component signals, representing the program material content of a color television signal, as a reference component signal with a reference timing signal to produce a reference delay signal;
- means for determining time differences between the reference component signal and each of the other color component signals;
- means for combining the time differences with the reference delay signal to produce a delay signal for each of the other color component signals;
- and
- means for delaying each of the color component signals according to their respective delay signals to produce delayed color component signals that are in time coincidence.
