METHOD FOR MEASURING CROSSVIEW BETWEEN TWO CHANNELS IN A WIRED TELEVISION BROADCASTING SYSTEM

摘要

ABSTRACT OF THE DISCLOSUREA method for measuring crossview between channels ina wired television broadcasting system is described in whicha pseudo random binary pulse sequence signal is applied to afirst channel, and the signal on a second channel iscorrelated with an identical sequence to provide an outputrepresentative of the crossview between the first and secondchannels. This enables crossview measurements to be easilymade without interrupting television signals on the channels.The pseudo random binary pulse sequence signal may be applieddirectly to the first channel or modulated on a carrierfor application to the first channel.
