Abstract
A method and system for implementing the pay-per-view DVD-ROM system, whereby the enabling data provided to the DVD-player allowing the playback of the DVD-ROM video data is provided to the DVD-player via the Internet or via the cable-TV system provider. The invention discriminates between DVD-ROM's requiring pay-per-view play, and those that are free and do not require pay-per-view play, by the use of a special code for the header of the DVD-ROM indicating a pay-per-view title. Also disclosed is use of a smart card or ATM card for receiving the enabling data for allowing playback of the Hyper-DVD disk.
Claims16
A method of playing back a large storage-capacity ROM-disk, comprising:
- (a) reading a ROM-disk via a player apparatus, and differentiating between a ROM-disk encoded to prevent playback thereof without enabling data, and a ROM-disk not encoded to prevent playback without enabling data;
- (b) playing the ROM-disk if it is not encoded to prevent playback without enabling data;
- (c) generating an enabling-data request to a service-provider to allow playback of the ROM-disk when said ROM-disk is encoded to prevent playback without enabling data;
- (d) receiving the enabling data from the service provider;
- and
- (e) enabling the playback of the ROM-disk with code to prevent playback by the player apparatus in response to said step (d);
- (f) said step (c) comprises inserting at least a smart card or ATM card into a remote-reading apparatus;
- (g) said step (d) comprising downloading the enabling data from a service-provider to the card via the remote-reading apparatus.
A ROM-disk playing apparatus for discriminating between a large storage-capacity ROM-disk having playback-prevent code means thereon and a ROM-disk not having playback-prevent code means thereon, comprising:
- a disk-player for playing back a ROM-disk;
- a microprocessor;
- memory means for storing software;
- software means comprising first means for detecting the presence of a ROM-disk having playback-prevent code means thereon;
- second means for retrieving enabling data for allowing playback of data on a ROM-disk;
- and third means for generating a trigger to allow said disk-player to playback said data on a ROM-disk;
- said second means comprising at least a smart card or an ATM card comprising means for storing thereon necessary information for allowing the downloading of the enabling data from a remote site to said at least one of a smart card and ATM card;
- remote means for reading said at least smart card or ATM card and downloading said enabling data to said at least smart card or ATM card;
- said at least smart card or ATM card, after having received said enabling data from said remote means, being used to transfer said enabling data to said memory means for allowing said ROM-disk to be played back.
