TRANSPORT STREAM GENERATING APPARATUS, TRANSPORT STREAM GENERATING METHOD, CONTENT DISTRIBUTION SERVER AND CONTROL METHOD OF CONTENT DISTRIBUTION SERVER

摘要

PROBLEM TO BE SOLVED: To solve the problem that repacketizing and re-multiplexing are required for a content distributed by VOD and the like after a Demux (packet separation) processing and a decoding processing are performed on TS data and caption data are added to data in the case of urgently inserting urgent disaster information by a caption, for example.

SOLUTION: In the transport stream generating apparatus, a caption packet is previously multiplexed/inserted into TS data and TS data are generated as NULL data, for example, even if character information to be displayed does not exist. A content distribution server device includes a function for overwriting new caption data and recording them in the case of urgently inserting and displaying new caption data into TS data generated by the transport stream generating device.
