A system and methods for the creation, management, and distribution of media
entity
fingerprinting are provided. In connection with a system that convergently merges
perceptual and digital signal processing analysis of media entities for purposes
of classifying the media entities, various means are provided to a user for automatically
processing fingerprints for media entities for distribution to participating users.
Techniques for providing efficient calculation and distribution of fingerprints
for use in satisfying copyright regulations and in facilitating the association
of meta data to media entities are included. In an illustrative implementation,
the fingerprints may be generated and stored allowing for persistence of media
from experience to experience. In various non-limiting embodiments, the processing
of fingerprints includes calculating the average information density of the media
entities, determining the standard deviation of the calculated information of the
media entities, calculating the average critical band energy of the media entities,
calculating the average standard deviation of the critical band energy of the media
entities, determining the play-time of the media entities and processing the information
density, the standard deviation of the information density, the critical band energy,
the standard deviation of the critical band, and the play time to produce a bit-sequence
representative of the fingerprint.
