Abstract

This paper focuses on live video distribution by video streaming technology. In general, it is an important challenge for video streaming to preserve spatial, temporal, continuous, and real-time quality of video. Pre-roll streaming, which buffers a certain amount of data before video playback, can retain spatial and temporal quality without degradation of continuous quality, while the problem about real-time quality remains because it is difficult to know data amount of video filmed in future on live video distribution. Hence, we propose the method to apply pre-roll sequentially for segmented video data divided by points where continuity of video content breaks, and show it can meet spatial, temporal and continuous quality with few degradation of real-time quality. In the experiment, we show the proposed method met other three qualities with few degradation of real-time quality for lecture video streaming.<br>
