发明名称 Conference apparatus and method for realistically reproducing image data and shared board data
摘要 A conference apparatus is adapted to advantageously perform a conference with a remote counterpart apparatus, store information on the events of the conference and then provide a realistic reproduction of those events. To this end, the conference apparatus includes an image memory for storing image information entered during the conference. A shared board presents the same image frame to the conference apparatus and to the counterpart apparatus, where the shared board is adapted to have shared information written therein by both the conference apparatus and by the counterpart apparatus, and a shared information memory, different from the image memory time-sequentially stores the shared information written into the shared board. To reproduce the conference in response to time information indicating a time corresponding to a portion of the stored shared information, the conference apparatus reproduces the stored shared information time-sequentially at a high speed until reaching the portion and thereafter synchronously reproduces both the stored image information and the stored shared information time-sequentially at a lower, substantially real-time speed to provide a realistic reproduction of events at the conference.
