An Adaptive Video Quality Control Method in Wireless Network Environment

In this paper, we propose QoS (quality of service) control methods for various type of video communication on wireless networks. In recent years, tablet PCs and smart phones have spread, and the video communication while moving is easy. However, that network performance varies with the distance between the device and the AP (access point) to change, to communicate while maintaining the video quality is difficult. Therefore, by controlling the video quality according to network performance, it is necessary to suppress the communication interruption or disturbance of the video communication. The video quality control will adjust the codec, resolution and frame rate. In this paper, we will verify the change of video quality due to the movement the video communication. We will evaluate the control method of the video quality at the time of movement.
