METHODS AND APPARATUS TO CREATE A MEDIA MEASUREMENT REFERENCE DATABASE FROM A PLURALITY OF DISTRIBUTED SOURCES

摘要

Methods and apparatus to create a media measurement reference database from a plurality of distributed sources are described. An example method of developing a reference database associated with media content includes receiving first identifying data associated with media content from a meter on a first information presentation device, the media content being locally accessible at the first information presentation device; determining whether the reference database includes reference data associated with the first identifying data; when the reference database lacks the reference data associated with the first identifying data, sending a message to the meter requesting first reference data for the media content; and receiving the first reference data associated with the first identifying data.
