Transport and acquisiton of drm-related information

A method of a reception apparatus for acquiring digital rights management (DRM)-related information, the method comprising:

• receiving a broadcast stream;
• extracting, from the broadcast stream, a service list table (SLT) including service information for each of a plurality of services in the broadcast stream;
• determining, by processing circuitry of the reception apparatus, whether the broadcast stream includes a DRM service that is supported by the reception apparatus based on service category information in the service information for the plurality of services in the broadcast stream, and
• acquiring the DRM-related information, which is associated with the reception apparatus and delivered in the DRM service, from a Layered Coding Transport (LCT) channel in the broadcast stream based on a determination in the determining that the broadcast stream includes the DRM service that is supported by the reception apparatus.

A non-transitory computer-readable medium storing instructions which when executed by a computer cause the computer to perform a method of a reception apparatus for acquiring digital rights management (DRM)-related information, the method comprising:

• receiving a broadcast stream;
• extracting, from the broadcast stream, a service list table (SLT) including service information for each of a plurality of services in the broadcast stream;
• determining whether the broadcast stream includes a DRM service that is supported by the reception apparatus based on service category information in the service information for the plurality of services in the broadcast stream, and
• acquiring the DRM-related information, which is associated with the reception apparatus and delivered in the DRM service, from a Layered Coding Transport (LCT) channel in the broadcast stream based on a determination in the determining that the broadcast stream includes the DRM service that is supported by the reception apparatus.

A service distribution system, comprising:

• processing circuitry configured to
• generate a service list table (SLT) including service information for each of a plurality of services to be transmitted in a broadcast stream, each of the service information including category information for a respective one of the plurality of services;
• generate the broadcast stream including the SLT and the plurality of services for transmission;
• and
• deliver DRM-related information in a DRM service of the plurality of services in a Layered Coding Transport (LCT) channel included in the broadcast stream, wherein
• the service category information included in the SLT for the DRM service is DRM Service.
