Method for providing protected audio/video content

Method for providing protected audio/video content for a content protection and copy management system based on a network of devices, comprising:

• obtaining primary data (PDat) representative of a content item (CI) to be provided;
• obtaining at least one of content usage rights information (CURI) and usage state information (USI), the content usage rights information (CURI) being descriptive of usage rights (US) and the usage state information (USI) being descriptive of a usage state (US) with respect to the content item (CI) to be provided;
• embedding at least one of said content usage rights information (CURI) and a derivative thereof into one of said primary data (PDat) and a derivative thereof, thereby generating secondary data (SDat) representative of the content item (CI) to be provided;
• and
• providing one of said secondary data (SDat) and a derivative thereof as said content item (CI) to be provided with the embedded content usage rights information (CURI),
• wherein said content usage rights information (CURI) is embedded repeatedly regularly within one of said primary data (PDat) and said derivative thereof and said repeatedly embedded content usage rights information (CURI) is the same content usage rights information (CURI) throughout said primary data and said derivative thereof.

A system comprising:

• a first obtaining unit that obtains primary data (PDat) representative of a content item (CI) to be provided;
• a second obtaining unit that obtains at least one of content usage rights information (CURI) and usage state information (USI), the content usage rights information (CURI) being descriptive of usage rights (UR) and the usage state information (USI) being descriptive of a usage state (US) with respect to the content item (CI) to be provided;
• an embedding unit that embeds at least one of said content usage rights information (CURI) the usage state information (USI), and a derivative thereof into one of said primary data (PDat) and a derivative thereof, thereby generating secondary data (SDat) representative of the content item (CI) to be provided;
• and
• a providing unit that provides one of said secondary data (SDat) and the derivative thereof as said content item (CI) to be provided with the embedded at least one of the content usage rights information (CURI) and the usage state information (USI),
• wherein at least one of said content usage rights information (CURI) and the usage state information (USI) is embedded repeatedly in a structured binary coded form within one of said primary data (PDat) and said derivative thereof and said repeatedly embedded content usage rights information (CURI) is the same content usage rights information (CURI) throughout said primary data and said derivative thereof and said repeatedly embedded usage state information (USI) is the same usage state information (USI) throughout said primary data and said derivative thereof.

A non-transitory computer readable storage medium having stored thereon a computer program which when executed by a processor causes the processor to perform a method comprising:

• obtaining primary data (PDat) representative of a content item (CI) to be provided;
• obtaining at least one of content usage rights information (CURI) and usage state information (USI), the content usage rights information (CURI) being descriptive of usage rights (UR) and the usage state information (USI) being descriptive of a usage state (US) with respect to the content item (CI) to be provided;
• embedding at least one of said content usage rights information (CURI) the usage state information (USI), and a derivative thereof into one of said primary data (PDat) and a derivative thereof, thereby generating secondary data (SDat) representative of the content item (CI) to be provided;
• and
• providing one of said secondary data (SDat) and the derivative thereof as said content item (CI) to be provided with the embedded at least one of the content usage rights information (CURI) and the usage state information (USI),
• wherein at least one of said content usage rights information (CURI) and the usage state information (USI) is embedded repeatedly in a structured binary coded form within one of said primary data (PDat) and said derivative thereof and said repeatedly embedded content usage rights information (CURI) is the same content usage rights information (CURI) throughout said primary data and said derivative thereof and said repeatedly embedded usage state information (USI) is the same usage state information (USI) throughout said primary data and said derivative thereof.

Method for providing protected audio/video content for a content protection and copy management system based on a network of devices, comprising:

• obtaining primary data (PDat) representative of a content item (CI) to be provided;
• obtaining at least one of content usage rights information (CURI) and usage state information (USI), the content usage rights information (CURI) being descriptive of usage rights (US) and the usage state information (USI) being descriptive of a usage state (US) with respect to the content item (CI) to be provided;
• embedding at least one of said usage state information (USI) and a derivative thereof into one of said primary data (PDat) and a derivative thereof, thereby generating secondary data (SDat) representative of the content item (CI) to be provided;
• and
• providing one of said secondary data (SDat) and a derivative thereof as said content item (CI) to be provided with the embedded usage state information (USI),
• wherein said usage state information (USI) is embedded repeatedly regularly within one of said primary data (PDat) and said derivative thereof and said repeatedly embedded usage state information (USI) is the same usage state information (USI) throughout said primary data and said derivative thereof.
