1. An information provisioning apparatus, comprising:
- an acquirer that acquires one of an audio and video elementary stream of content that is composed of a plurality of segments, and actual data of metadata that includes information related to the content;
a unitizer that divides the metadata into metadata processing units (MPU) corresponding to segments subjected to processing in the plurality of segments; and
a multiplexer that generates a transport stream of a MPEG-2 system that includes packetized elementary stream (PES) packets acquired by packetizing the segments of the data stream and metadata PES packets acquired by packetizing at least one MPU.

Abstract
Information provisioning includes acquiring one of an audio and a video elementary stream of content that is composed of a plurality of segments, and actual data of metadata that includes information related to the content. The metadata is divided into metadata processing units (MPU) corresponding to segments subjected to processing in the plurality of segments. A transport stream of a MPEG-2 system is generated that includes packetized elementary stream (PES) packets acquired by packetizing the segments of the data stream and metadata PES packets acquired by packetizing at least one MPU.

5. An information provisioning method, comprising:
-
acquiring, by executing a set of instructions by a computer, one of an audio and video elementary stream of content that is composed of a plurality of segments, and actual data of metadata that includes information related to the content; dividing, by executing the set of instructions by the computer, the metadata into metadata processing units (MPU) corresponding to segments subjected to processing in the plurality of segments; and generating, by executing the set of instructions by the computer, a multiplexed transport stream of a MPEG-2 system that includes packetized elementary stream (PES) packets acquired by packetizing the segments of the data stream and metadata PES packets acquired by packetizing at least one MPU. - View Dependent Claims (6, 7, 9)
