Video Streaming Strategy Based on Feedback Control Loop Theory in Cloud Platform

摘要

The main purpose of this paper is to run video games over the cloud while optimizing the synergy between the client and the server in order to increase player performances. One of the strengths of cloud gaming is elasticity which helps matching user's requirements with available allocated resources. Our major contribution is a new video streaming strategy based on the Feedback Control Loop theory which is designed to ensure an optimal usage of the player and the video quality. So we focus on how to automatically tune the video quality to meet with the available network resources and so increase the user's video quality. In our scheme, the server stores several streams at different quality and resolution then switches among them during the play back in order to match user bandwidth and CPU. Comparing our proposed approach to traditional streaming techniques shows its better performance in term of Frame Rate witch remains unchanged, while the resolution of the video matches the available bandwidth at the terminal.
