    Abstract: A reception apparatus includes receiver and processing circuitry. The receiving circuitry is configured to receive a broadcast stream. The processing circuitry is configured to extract a service list table (SLT) from the broadcast stream. The SLT includes service information for each of a plurality of services in the broadcast stream. The processing circuitry is configured to determine whether the broadcast stream includes a digital rights management (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. The processing circuitry is configured to acquire DRM-related information, which is associated with the reception apparatus and delivered in the DRM service, based on a determination that the broadcast stream includes the DRM service that is supported by the reception apparatus.

    Abstract: A method, non-transitory computer-readable storage medium, and reception apparatus for extracting metadata, and an information providing apparatus for providing the metadata. The method for extracting metadata includes processing, by circuitry of the reception apparatus, content that includes the metadata embedded therein. The metadata is embedded as a watermark in a first portion of a video frame of the content. The circuitry determines symbol values of the watermark from the video frame based on luminance values in pixels of the first portion of the video frame of the content to extract the metadata. At least one of the luminance values is less than 16.
