<p>A system that utilizes a determined unique characteristic from content for subsequently identifying the content and/or the corresponding content review position in the time domain. The system utilizes a database of previously stored unique characteristics from known content for matching to the determined unique characteristic from the content source. The unique characteristics may correspond to video tape indexing data, keyframe data, audio characteristics, text occurrences, and/or other known characteristics from the content. When a match is found between the determined unique characteristic and the stored unique characteristics, the system identifies the content. When corresponding time domain data is stored in the database, the system identifies the current content review position in the time domain. When the unique characteristic from the content does not match any of the unique characteristics stored in the database, the system stores the current unique characteristic and corresponding content identifying information in the database for identifying the content at some subsequent time.</p> |
