Paper Abstract

We have developed a TV-on-demand system, which provides playback of a television program after a period ranging from a few seconds to one week after broadcast, and have conducted usage trials in cooperation with a television station in Nagano Prefecture of Japan. This system has been achieved through the development of various technologies, such as automatic updating of stored television programs and contents retrieval by telop characters. Users in the trials can begin playback of a television program immediately after its broadcast has begun. The purpose of the trials was to evaluate the system's usability in applications, such as contents retrieval, selective viewing of commercials, and customer service at the television station. This paper presents applied technologies and some experimental results, and also addresses a new direction of information retrieval system based on the evaluation of the usage trials.
