Abstract

Recently, demand of presentation video is increasing so that various conferences provide the streaming service of presentation video. In many cases, presentation slides and posters in the streaming video are not so visible because of various reasons such as low resolution and distortion. Users cannot understand the presentation clearly in such situation. In this paper, we propose a streaming video augmentation method to improve the visibility of the content in the streaming video. In the method, the client downloads the original data of the content in the streaming video previously. Then, in the watching phase, the image generated from original data is superimposed at the location of the content area in the streaming video. We implemented poster presentation live streaming system. We also conducted experiment of the system. In result, we found out that the system improve the visibility of poster in the streaming video, and reduce the flustration of watching the video.
