ZEUS: Network Aware QoS Management for Immersive Environment

The production value accomplished with virtual studio applications is becoming more attractive to the modern broadcasting studios. One of the drawbacks in today's virtual studio is the limitation of viewpoint. Virtual studios using multiple cameras can overcome the restriction of viewpoint. To efficiently deliver the continuous media(CM) from a studio to viewers, we must consider the heterogeneous, irregular network environments. In this paper, we focus on the guarantee of constant playback in the IP network. We present the network aware QoS management for immersive environment to deliver the media in time and at the same time, to minimize the quality variation. We propose the adaptive QoS management scheme to minimize the quality variability while at the same time maximize the utilization of variable network bandwidth. As a result, the stable frame transmission rate is guaranteed and the quality fluctuation becomes smoother.
