Abstract
Digital content, such as video, audio, multimedia, and similar files may be segmented at a determined frame resolution rate and analyzed to determine a fingerprint for each content segment. An identifier that uniquely identifies each content segment may be determined based on the fingerprint of the respective content segment. The identifier may be associated with data relating to the content segment and with one or more identifiers that uniquely identify other content segments of the content. The content segment identifiers may be used to construct a content segment sequencing representation that represents the playback of the content segments in playback order.
