A Technique for Streaming Multiple Video Parts in Parallel Based on Dash.js

摘要

Watching video on the Internet has become an alternative to offline video playback on video player software. Videos on the Internet are streamed to video player so that they can be played without having to wait for the whole files to be downloaded. However, when playing a video, some users may skip ahead to different positions or scenes in the video to see whether the video is really of their interest. Most video players only stream videos from the beginning, thus jumping to a part of a video that has not been streamed causes a delay while the video starts to buffer. In this paper, we propose a technique to stream multiple parts of a video simultaneously by modifying the dash.js framework so that users can navigate to different points in a video with minimal delay. The prototype that realizes our concept proves the feasibility of our approach. With further improvement, our technique may contribute to the scene selection function for video streaming, similar to that of video player software.
