Method of and system for identification and verification of broadcasted program segments

In a system for identification and verification of broadcasted program segments from a plurality of broadcasting stations,

• at least one monitoring station for receiving broadcasted signals from said broadcasting stations, said monitoring station including (a) means for generating date-indicating and tie-indicating signals, (b) respective channels responsive to respective broadcasted signals from respective broadcasting stations for recovering a subaudible preamble code, respective subaudible program segment identification codes and a subaudible postamble code, and (c) means for providing respective broadcast station-identification signals;
• means at the monitoring station for storing data signal representations of each recovered preamble code, recovered respective program identification codes and postamble code, the date-indicating and time-indicating signals, and the station-identifying signals for each channel;
• and
• means at the monitoring station for sending the stored data signal representations to a central station, the central station being provided with means for receiving data from a plurality of monitoring stations to compile and/or to reconcile same.

• wherein the alphanumeric characters are formed by a series of mark signals and space signals, defined by presence and absence of a 40 Hz. subaudible tone.

Method of identification and verification of broadcasted program segments, the method comprising:

• providing program segments having a subaudible preamble code, respective subaudible program segment identification codes and a subaudible postamble code;
• broadcasting the program segments from a plurality of broadcast stations;
• receiving at a monitoring location broadcasted signals, including the program segments, from the plurality of broadcast stations;
• deriving from the received broadcast signals the preamble code, the respective program segment identification codes and the postamble code;
• providing at the monitoring location respective broadcast station identification signals;
• generating at the monitoring location respective date-indicating and time-indicating signals;
• storing at the monitoring location signals representing the preamble code, the respective program segment identification codes and the postamble code when received, each broadcast station identification signal from which each program segment was received each time it is received therefrom and the date-indicating and time-indicating signals each time a program segment is received;
• and
• sending the stored signals as data to a central point which also receives data from other monitoring locations for compilation and/or reconciliation.
