A computer system and method for identifying and associating metadata across related media with the same content, the system comprising: one or more processors operative to execute instructions; an operative connection to a plurality of databases comprising: a segment database comprising a plurality of segments, each segment comprising a segment ID corresponding to a segment of a media item; a signature database, the signature database including signatures for identified media; a media playlist database; a metadata database; and non-transitory memory operatively coupled to at least one of the including computer executable instructions; the one or more processors programmed at least to, when the program memory instructions are executed by the processors,
a) sample a signature for a new media item;
b) compare the signature sample of the new media item against the signature database to identify at least one segment associated with the signature in common with a matching media item;
c) retrieve a media playlist associated with the one or more previously identified segments for the matching media item from the media playlist database, each media playlist associated with one or more segments and a start time, and an end time corresponding to a each segment of a media item
d) assign one or more segment IDs to the common segments associated with the signature in the new media item at a time location in a segment playlist for the new media item;
e) identify a segment within the sample of the new media item;
f) repeat steps b) through d) on the unidentified segment; and
g) repeat steps e) and f) until all matching media items and commonly identified segments are identified and assigned to the new media item, and
h) save the segment playlist for the new media item as a new media playlist,
wherein metadata from at least one metadata database is associated with each of the one or more segments. |
