Method of and system for identification and verification of broadcasting television and radio program segments

In a system for identification and verification of broadcasted program segments from a plurality of broadcasting stations, including at least one television broadcasting station,

• at least one monitoring station for receiving broadcasted signals from said broadcasting stations, said monitoring station including (a) means for generating date-indicating and time-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, a subaudible postamble code, and, for monitored television broadcast stations, each video signal to develop therefrom a video presence and/or absence signals at least during periods between each received preamble code and each received 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 video presence and/or absence signals, 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 station being provided with means for receiving data from a plurality of monitoring stations to compile and/or to reconcile same.

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, at least one of which is a television broadcast station;
• 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 and, in the case of broadcast signals from television broadcast stations, video presence and/or absence signals;
• 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, the postamble code when received and the video presence signals, each broadcast station identification signal from which each program segment was received each time, it is received therefrom, the date-indicating and time-indicating signals each time a program segment is received and the video presence and/or absence signals at least during periods between the respective preamble codes and respective postamble codes;
• and
• sending the stored signals as data to a central point which also receives data from other monitoring locations for compilation and/or reconciliation.

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;
• receiving at a monitoring location broadcasted signals, including the program segments, from a plurality of broadcast stations, including at least one television broadcast station;
• deriving from the received broadcast signals the preamble code, the respective program segment identification codes, the postamble code and, in the case of signals from television broadcast stations, video presence and/or absence signals at least during periods between the respective preamble codes and the respective postamble codes;
• 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 recovered preamble code, the respective program segment identification codes and the postamble code, when received, the video presence and/or absence signals, 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.

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;
• receiving at a monitoring location broadcasted signals, including the program segments, from the plurality of broadcast stations, including at least one television broadcast station;
• deriving from the received broadcast signals the preamble code, the respective program segment identification codes, the postamble code and, in the case of signals from television broadcast stations, video presence and/or absence signals at least during periods between occurrences of the preamble code and the postamble code;
• providing at the monitoring station respective broadcast station identification signals;
• generating at the monitoring location respective date-indicating and time-indicating signals;
• and
• storing at the monitoring location data signals representing the preamble code, the respective program segment identification codes, the postamble code when received and, in the case of video, the video presence and/or absence signals, 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 containing a commercial message is received.

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

• providing program segments having respective subaudible program segment identification codes and a postamble code;
• receiving at a monitoring location broadcasted signals, including the program segments, from a plurality of broadcast stations, including at least one television broadcast station;
• deriving from the received broadcast signals the respective program segment identification codes, the postamble code and, in cases of broadcasted television program segments, video presence and/or absence signals;
• providing at the monitoring station respective broadcast station identification signals;
• generating at the monitoring location respective date-indicating and time-indicating signals;
• and
• storing at the monitoring location data signals representing the respective program segment identification codes when received and the video presence and/or absence signals, 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.
