Coded Information within the Picture Area

Wilton R. Holm

In years past, the Federal Communications Commission (FCC) has authorized a variety of special signals inserted into or riding “piggyback” with the television program signal. These special or “ancillary” signals were included for a number of purposes, and without in any way adversely affecting the integrity of the program signal. But in 1970 the FCC amended its Rules and Regulations so as to permit transmission of coded patterns in the television picture area, which signals “shall not result in significant degradation of broadcast transmission.”
