Consideration of transcoding using updatable scalability for selective quality video content delivery method

In this paper, we propose a video access model with guaranteed bandwidth by considering data transmission and browsing. Moreover, we propose a video content delivery method with scalable transcoding, when users use multi-quality video, and evaluate the transcoding time in our video access model. From the viewpoint of transcoding time, the influence of user access time is clear in this model, comparing the proposed method with the simulcast type by simulation experiments.
