Claim:
An information provisioning apparatus, comprising: an acquirer that acquires an audio elementary stream and a video elementary stream of content that is composed of a plurality of segments, and metadata that includes information describing the content; a unitizer that divides the metadata into a plurality of metadata processing units, wherein a metadata processing unit (MPU) indicates a unit of the metadata and corresponds to a segment of the content, the MPU and the segment are configured to be processed for performing partial execution of the metadata in synchronization with the segment of the content; and a multiplexer that generates a transport stream of a MPEG-2 system by multiplexing audio packetized elementary stream (PES) packets acquired by packetizing the audio elementary stream, video PES packets acquired by packetizing the video elementary stream, and metadata PES packets acquired by packetizing the MPU, wherein the MPU identifies a processing start time of the segment of the content for performing the partial execution of the metadata in synchronization with the segment of the content.
