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.
