ABSTRACT:
An automated program/commercial identification system that encodes and decodes an encoded data frame, which is added to an original program segment before it is broadcast. Within each encoded data frame, data is encoded to identify the original program segment and its prescribed time duration. A plurality of encoded data frames, altered by sequence codes, are repetitively generated for the duration of the encoded program segment to verify the encoded program segment's integrity. A phase-shift keyed modulation technique is used to place the encoded data frames in a notched-out section of the original program segment's audio channel, forming an encoded audio channel within the encoded program segment. Verification of the integrity of the encoded audio channel of the encoded program segment is achieved by monitoring the integrity of each encoded data frame. Additionally, the encoded program segment's video channel is verified by monitoring the integrity of the video channel's black/white or composite video levels and its sync level amplitude. Data from the encoded data frames is accumulated by one or more monitoring stations using a separate tuner for each monitored radio, television, or cable broadcaster. The encoded data is demodulated by sensing peaks in the phase-shift keyed subcarrier or, alternatively by correlating the modulated subcarrier with a local reference. The monitoring stations periodically transfer this data to a central computer, which compares this accumulated data to assigned program times for each encoded program segment and compiles a confirmation/discrepancy report.
