Media usage monitoring and measurement system and method
First Claim
1. A media measurement method comprising:
- receiving, at one or more computers, audio data from a monitoring device, the audio data being divisible into samples; and
determining, using the one or more computers, a next sample of the audio data for attempted identification of a media content item corresponding to the next sample by adjusting a length of a time window of the next sample based at least in part upon a result of an attempt using the one or more computers to identify a first prior sample as corresponding to a media content item stored in a computerized database of reference content;
wherein, if the attempt to identify the first prior sample indicates a result that is different than a result of an attempt to identify a second prior sample, then the time length window of the next sample is changed relative to a time window of the first prior sample.

Abstract
Media monitoring and measurement systems and methods are disclosed. Some embodiments of the present invention provide a media measurement system and method that utilizes audience data to enhance content identifications. Some embodiments analyze media player log data to enhance content identification. Other embodiments of the present invention analyze sample sequence data to enhance content identifications. Other embodiments analyze sequence data to enhance content identification and/or to establish channel identification. Yet other embodiments provide a system and method in which sample construction and selection parameters are adjusted based upon identification results. Yet other embodiments provide a method in which play-altering activity of an audience member is deduced from content offset values of identifications corresponding to captured samples. Yet other embodiments provide a monitoring and measurement system in which a media monitoring device is adapted to receive a wireless or non-wireless audio signal from a media player, the audio signal also being received wirelessly by headphones of a user of the monitoring device.

11. A media measurement method comprising:
-
receiving, at one or more computers, audio data from a monitoring device, the audio data being divisible into samples; and determining, using the one or more computers, a next sample for attempted identification based at least in part upon a result of an attempt using the one or more computers to identify prior samples against a computerized database of known content wherein determining the next sample comprises selecting a relative time location of the next sample within the audio data such that if a result of attempting to identify a first prior sample against the computerized database of known content differs from a result of attempting to identify a second prior sample against the computerized database of known content, then the relative time location of the next sample within the audio data is selected to be between a relative time location of the first prior sample and a relative time location of the second prior sample. - View Dependent Claims (12, 13, 14, 15, 16, 17)
