The error-prone nature of wireless communication makes it hard for the traditional error recovery techniques to promptly recover different priority lost video packets. In this paper, we extend an intelligent Forward Error Correction (FEC) mechanism, Enhanced Adaptive FEC (EAFEC), to further propose and analyze the efficiency of using different FEC strength depending on H.264/SVC video stream priorities...
In recent years, the mobile equipments with powerful functions and convenient service feature are getting more and more popular. Those mobile equipments not only provide us many types of wireless network connections services but also with one of popular service which is video streaming. However, the most concerned problem is handover between networks during the video streaming transmission. So we...
With rapid advances in multimedia and wireless network technologies, it is now feasible to provide live video streaming over wireless networks. However, since bandwidth is a scarce resource in wireless networks, it is important to design an adaptive bandwidth allocation scheme for video streams to make efficient use of wireless bandwidth. In this paper, we propose an adaptive bandwidth allocation...
When measuring the performance of MPEG-4 transmission in IEEE 802.15.3 WPAN, the drop scheme used can have a considerable influence on Mean Propagation Time, Job Failure Rate and composite metrics. Active Queue Management (AQM) is an effective method to provide an early notification of network congestion by pro-actively dropping or marking packets. In this paper, we analyze the performance of MPEG-4...
