The existing QoS mechanisms for video streaming are short of the consideration for various user environments and the characteristic of streaming applying programs. In order to overwhelm this problem, studies on the video streaming protocols exploiting scalable video coding (SVC), which provide spatial, temporal, and qualitative scalability in video coding, are progressing actively. However, these...
As the rapid growth of multimedia communication demand, it is inevitable to develop a method that could convey multimedia applications on IP network that is previously a text-based communication. In this research, we implement and investigate the H.264 and MPEG-4 video codec, as well as the quality of their transport over wireless environment, particularly mobile IPv4 and adhoc networks. Video quality...
Goal of the reported experiment was to determine in which way wirelessly transmitted video streams influence each other. Former experiments gave the impression that the behavior of video streams is unpredictable, e.g. due to unstable play-back and uncertain starts. To transport two video streams simultaneously over a wireless/wired network, the video servers use different network protocols (TCP and...
