Patent abstract
Access to an audiovisual product is controlled by obscuring data. Cells 420 of audiovisual data A, B, C are reproduced by a sequence instruction 410 (e.g. a PGC or Program Chain). One such sequence instruction 410a correctly reproduces the audiovisual data A, B, C, but is hidden amongst many other sequence instructions 410b which incorrectly reproduce the sequence of cells 420 (e.g. as BAC, ACB, CAB, etc.).
