Metadata generation and distribution for live programs on broadcasting-telecommunication linkage services

This paper describes SceneCabinet/Live!, which is a system that generates real-time segment metadata using audio/video indexing and natural language processing to provide viewers with a continuously metadata update service of live programs. It significantly reduces the costs of generating segment metadata that is relevant to the viewer and reduces the time by about half. It enables metadata to be sent without delay in a metadata updateable service. We approached using audio/video recognition technologies to make index of the scene like a book because video programs are difficult to search scenes in. Segment metadata is used on broadcasting-telecommunication linkage services, affording a new way to view programs on optical and broadcast networks by supporting TV digests and videos from VoD services. These new metadata services are more convenient to use and more enjoyable to watch than conventional ones.
