Patent ID: 8438591

Claim:
Software stored in one or more computer-readable storage devices and storing instructions executable by one or more computers that upon such execution cause the one or more computers to perform operations comprising: identifying channel tunes and corresponding tune times of television processing devices from reporting data related to television processing devices; for each television processing device: identify channel tune cluster pairs, each channel tune cluster pair being a first channel tune-in to a first channel at a first time and a subsequent channel tune out for the first channel at a second time and without an intervening channel tune-in or tune-out between the first time and the second time, the first time occurring before the second time; for each channel tune cluster pair, determining a dwell time based on a difference between the first time and the second time; determining that only channel tunes for channel tune cluster pairs having a dwell time that is a characteristic dwell time are automatically generated channel tunes, wherein each characteristic dwell time is indicative of a channel tune generated by a programmed recording device.
