Patent ID: 8238727

Claim:
A method of detecting a time shift event comprising: calculating a presentation gap value corresponding to a difference between a start presentation time of a second metering event and an end presentation time of a first metering event, the first metering event representative of a first time period in which a first program was continuously presented on an information presenting device, the second metering event representative of a second time period in which a second program was continuously presented on an information presenting device, and the first and second time periods being sequential; calculating a broadcast jump value corresponding to a difference between a start broadcast time of the second metering event and an end broadcast time of the first metering event; comparing, using a logic circuit, the broadcast jump value to a first threshold, comparing the presentation gap value to a second threshold, and comparing the broadcast jump value to the presentation gap value to determine whether a pause event, a fast forward event or a rewind event occurred.
