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.
