ABSTRACT:
Information provisioning includes acquiring a data stream of content that is composed of a plurality of segments, and actual data of metadata that includes information related to the content and information related to the plurality of segments. The metadata is divided into metadata processing units (MPU) corresponding to segments subjected to processing in the plurality of segments. A capsulized stream is generated that includes packetized elementary stream (PES) packets acquired by packetizing the segments subjected to processing of the data stream and metadata PES packets acquired by packetizing at least one MPU, the metadata PES packets including control information of the metadata. The control information includes an overwrite_flag which indicates whether previous metadata is to be overwritten.
