Abstract: Determinar y ocultar un período reemplazable de una MP (Presentación de medios). Un método para la determinación incluye recibir una primera MPD (Descripción de Presentación de Medios) que identifica un período predeterminado y al menos un segmento de medios de la MP que se presentará durante el período predeterminado. Se determina si la primera MPD incluye datos adicionales que serán resueltos por una aplicación. Los datos adicionales se proporcionan a la aplicación cuando se determina que la primera MPD incluye los datos adicionales. Se recibe de la aplicación la información de período adicional. Se genera una segunda MPD basada en la información de período adicional recibida. Se emite la MP para mostrar a un usuario con base en la segunda MPD. Cada uno de un subconjunto del al menos un segmento de medios para un sub-período reemplazable de la MP se puede reemplazar por un segmento de medios alternativo.

Abstract: 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.

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.
