Apparatus of a flexible and common IPMP system for MPEG-2 content distribution and protection

A terminal side apparatus for an intellectual property management and protection (IPMP) system for Moving Picture Expert Group-2 (MPEG-2) content distribution and protection, comprising:

• a de-multiplexer that de-multiplexes IPMP control information including an IPMP tool list from an MPEG-2 content stream sent from a content provider;
• an IPMP tool list interpreter that interprets the IPMP tool list;
• an IPMP tool retriever that retrieves a missing IPMP tool based on the IPMP tool list;
• a control graph interpreter that interprets an IPMP control graph and obtains information relating an IPMP tool to a stream controlled by the IPMP tool at a control point;
• and
• an interactor that interacts with at least one IPMP tool through a pre-defined messaging interface at the control point.

A content provider side apparatus for an intellectual property management and protection (IPMP) system for Moving Picture Expert Group-2 (MPEG-2) content distribution and protection, comprising:

• an encoder that encodes a content into an MPEG-2 content stream;
• an encryptor that encrypts the encoded MPEG-2 content stream using at least one IPMP tool;
• an IPMP tool list creator that creates an IPMP tool list of at least one IPMP tool used for encrypting the encoded content;
• a control graph creator that creates an IPMP control graph that indicates how the at least one IPMP tool protects the MPEG-2 content stream;
• a control information multiplexer that multiplexes IPMP control information including the IPMP tool list into an IPMP control information PES packet for a program stream;
• and
• a general multiplexer that multiplexes the encrypted content stream with the IPMP control information PES packet, using an MPEG-2 systems,
• an outputter that outputs the multiplexed encrypted content stream.
