Abstract
The disclosure is of a system and method of detecting or identifying a received TV program by forming a database of identifying digital bits for a plurality of programs, processing a TV program by modulating the luminance of pairs of lines of the program and reconstituting the program with said modulated line pairs and the other components of a TV program signal. The reconstituted program is transmitted to a location at which it is decoded to recover the digital identifying bits and comparing such bits with bits in the database to identify the transmitted program.
