N2 - In this paper, we introduce a real-time metadata service system that is implemented for live digital broadcast TV programs. The system is composed of three parts: an indexing host which indexes broadcast programs in real-time, a broadcaster where the segmentation metadata delivered from the indexing host is multiplexed into the broadcast stream and transferred to clients, and a client PVR that receives the metadata and locates a segment of interest from the recorded stream according to the time description of the delivered metadata. We propose to utilize broadcasting time for a time description of the segmentation metadata, so as to be free from the media localization problems in broadcast environment. In addition, we utilize a spatiotemporal visual pattern of a video for a verification tool of real-time indexing, such that we can reduce the false alarms of video segmentation caused by lack of an efficient tool for verifying video segment. As a result, we show the real experiments that are performed without requiring a return channel and demonstrate the feasibility of the proposed system.
