Abstract:
A reception apparatus includes receiver and processing circuitry. The receiver circuitry is configured to receive a broadcast stream including a service list table (SLT) and a digital rights management (DRM) data service. The SLT includes service information for the DRM data service. The processing circuitry is configured to extract the service information for the DRM data service from the SLT included in the received broadcast stream. The service information for the DRM data service includes a DRM system identifier. The processing circuitry is configured to acquire DRM information from the DRM data service based on whether a condition regarding the reception apparatus or a user of the reception apparatus is satisfied.
