Patent abstract
Access to an audiovisual product 40 is controlled by requiring a user to enter an access code 80. The audiovisual product 40 comprises cells 420 of data whose playback sequence is controlled by a plurality of sequence instructions 410 each having a predetermined structure location within the audiovisual product. A destination function is applied to the access code 80, in order to calculate a destination structure location. Jumping to the calculated location leads to a sequence instruction (e.g. a PGC—Program Chain) to initiate playback of the audiovisual product (e.g. a DVD-Video product).
