Abstract: A method and system is provided for doing compact disc TOC look-ups cheaply and efficiently by using a special indexing mechanism particularized to TOC look-ups. The indexing scheme allows a successful search of TOCs using as few as 2 disk seeks in contrast to the usual hundreds of disk seeks required by a general purpose indexing scheme. This performance improvement is achieved by using a static database of TOCs in a read-only implementation so that the data organization and code for lookups can be optimized without regard for any updates to this data at a later time. The index data structure is arranged in a fashion that allows for seek-less, linear scans of index information once the proper scan location in the index has been identified.

Abstract: A copy-protected compact disc includes, within a single session, a table of contents (TOC) and a Video CD index (VI). Each track (T) is prefaced by unrecoverable data (UD) at a track start position (ATOC) indicated by the table of contents (TOC). However, the Video CD index (VI) indicates the actual position (AP) of the tracks. DVD players use the Video CD index (VI) to locate the tracks, while the CD-ROM drives use the table of contents (TOC) and read the unrecoverable data (UD), which prevents them from reading the subsequent track (T). The unrecoverable data (UD) may be prefaced by data pointers (DP) which cause the CD-ROM drive to load a player program in response to the error condition. The player program can be used to play the tracks (T), but restricts copying. Subchannel data (P; DX) causes audio CD players to ignore the Video CD index (VI) and the unrecoverable data (UD), and to play the tracks (T) at their actual start positions (AP).
