Determining and hiding a replaceable period of a MP (Media Presentation). A method for determining includes receiving a first MPD (Media Presentation Description) that identifies a predetermined period and at least one media segment of the MP to be presented during the predetermined period. A determination is made as to whether the first MPD includes additional data to be resolved by an application. The additional data is provided to the application when the first MPD is determined to include the additional data. Additional period information is received from the application. A second MPD is generated based on the received additional period information. The MP is output for display to a user based on the second MPD. Each of a subset of the at least one media segment for a replaceable sub-period of the MP is replaceable with an alternate media segment.

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.

System for distributing metadata embedded in video

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.

Transport and acquisition of DRM-related information

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.

Techniques are described for efficient delivery and reception of information, such as an Entitlement Management Message (EMM), that is related to Digital Rights Management (DRM) in a terrestrial broadcast system such as ATSC 3.0.

Delivery of information related to digital rights management (DRM) in a terrestrial broadcast system

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 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 when the DRM system identifier included in the service information for the DRM data service corresponds to a DRM system that is supported by the reception apparatus.
