Abstract
A system and apparatus for compensating cable losses in a video signal transmission system includes feedback circuits to determine the spectral attenuation of a received signal and to control an equalizer circuit to amplify selected frequencies of the received signal, and to determine the various times of arrival of two or more video signals and selectively adjust one or more delay lines to reduce the differences in their arrival times.
