Broadcast metadata providing system for hybridcast

Hybrid TV services offered with a technology platform called "Hybridcast" have launched in Japan. To make the services more attractive, it is expected that various service providers such as third parties will provide Hybridcast services. In this paper, we propose a broadcast metadata providing system that enables third parties to create advanced hybrid TV services on Hybridcast. Using a prototype system, we demonstrate the feasibility of the proposed system.
