Learning fro TV programs: application of TV presentation to a videconferencing system

摘要

In this paper, we propose to direct the visual image of a videoconferencing system. Pictures of current videconferencing systems are often boring. We through presentation of pictures on TV and in movies should be studied to improve videoconferencing. For this purpose, we investigated several debate programs on TV. We classified all the shots into eight classes, and then determined the duration of each shot and the transition probabilities among the calsses in order to describe the structure of TV programs. From this, rules to control pictures have been obtained. After that, we made a two-point multi-party videoconferencing system that utilizes the rules. The system includes automated control of changes in cameral focus.
