Patent ID: 8869187

Claim:
A method comprising: processing first bus information obtained by monitoring a bus of a time shifting device to determine a first time at which the time-shifting device stored data associated with first media being recorded for later presentation; processing second bus information obtained by monitoring the bus of the time shifting device to determine a second time, later than the first time, at which the time-shifting device later retrieved the stored data to present the recorded first media, the first time and the second time being determined from a first clock tracking local time for the time-shifting device; determining a third time at which the time-shifting device presented the recorded first media, the third time being determined from a second clock different from the first clock, the second clock tracking real time; and subtracting from the third time a difference between the second time and the first time to estimate a possible distribution time corresponding to when the first media was initially distributed to the time-shifting device.
