Abstract:
A computer system for associating one or more features codes with one or more reference streams, the system comprising:one or more central processing units and one or more memories; and an index generation process that creates one or more of the feature codes by performing the steps of: selecting a key interval from a reference stream; transforming a media region of one or more selected key intervals of the media stream into one or more characteristic feature spaces; quantizing the characteristic spaces into one or more domain regions; deriving domain codes based on one or more domain regions selected from one or more characteristic spaces; quantizing one or more feature values to determine the feature codes associated with each domain region; and using the feature and domain codes to index into a memory index structure which associates the respective feature codes and domain codes with one or more parts of the reference streams from which they were derived.
