Outline of Final Research Achievements

We face a big issue when a highly interactive multiple-video is provided to a huge number of users simultaneously across a network. The dominant technical problem is the processing speed and delay. In order to reduce this issues, the degradation of its video quality is critical.
In this research project, we tackle this trade-off problem. In addition, it is essential to provide high functional media orchestration.
To this end, we proposed a video control scheme to avoid the degradation of the video quality while keeping the processing time and delay lower. We also proposed some media recognition schemes and visualization schemes. The results show that the proposed methods are feasible and outperform than the existing methods.
