Abstract

The current computer technology enables us to build huge broadcast video archives which had been a future dream. Today, even the hard disk recorders on the market are capable of recording several hundred hours of broadcast video. It is naturally perceived that a huge amount of broadcast video would be a useful corpus for multimedia indexing and mining research. Based on this viewpoint, we designed and constructed a broadcast video archive system having sufficient capacity and functionality to serve as the testbed for indexing and mining research. The system can capture multiple channels (currently seven channels) all-day broadcast video streams simultaneously, up to 6000 hours, and program-specific broadcasts, currently a news program for more than three years so far. This paper discusses design and implementation issues of the video archive system and then introduces our research efforts utilizing the archives as huge multimedia corpora.
