Abstract: A content distribution system and method which prevents unauthorized access to secured content such as movies and music. The system includes a source, a receiver, an authorized security device such as a conditional access module (CAM) for decrypting authorized content and an output device for outputting content. The system can also include a backend for managing accounts and system operations. One aspect of this invention is that the content data is derived from the Internet. The system allows for the verification of authorization to play secured content, the addition of watermarks to the secured content, the conversion of the secured content to a displayable form and the means for preventing output of the secured content.

The apparatus includes a source, a receiver, an authorized security device such as a conditional access module (CAM) for decrypting authorized content, an output device for outputting content and a backend for managing accounts and system operations. One aspect of this invention provides a mechanism for providing secured content on a medium such as a DVD optical disc. These devices may verify that there is authorization to play the secured content, add watermarks to the secured content, convert the secured content to a displayable form and provide a means for preventing output of the secured content.

Abstract: A structure and method are described that make it possible to store both open-format data and closed-format data on a single storage medium, such as a DVD disc, by organizing the data in an open file data system and a specialized closed file data system. The closed file data system may be encapsulated in the open file data system The storage medium is segmented into open file data spaces, containing data recorded using the open-format techniques, and closed file data spaces, containing data recorded using closed-format techniques, or using a specialized technique. The open-format data can be accessed using both open-format and close-format hardware, whereas the closed-format data can only be accessed using specialized hardware.

Abstract: A transport packet generation apparatus and method used in a system which delivers content such as movies and music is disclosed. This invention provides a mechanism for providing and retrieving content on a medium such as a DVD optical disc. One aspect of the present invention provides content by processing and packing data packets onto the medium. A further aspect of the present invention retrieves content by reading data off the medium and processing the data to functionally reconstruct the original data packets for use in the system for delivering content.
