ABSTRACT:
Methods and systems for indexing programs are described. In accordance with one embodiment, program data associated with a program recorded on a first entertainment system is processed sufficient to create one or more signatures. The signatures define points of reference that can be utilized to synchronize timecodes associated with other recorded versions of the program from which the signatures were created. One or more indices are created and associated with the program from which the signatures were created. An index file can be created and can contain the created indices as well as the created signatures. A client system that receives the index file can use the signatures to synchronize the timecode on its recorded version of the program with a timecode of the program from which the signatures were created. Once the timecodes are synchronized, the client system can locate the same indices on its recorded version of the program.
