An efficient intra-prediction mode decision mechanism for H.264/AVC is presented in this research. A projection-based approach, which employs the reconstructed surrounding pixels and block content to compute the predicted block residuals (PBR), can effectively eliminate less probable modes from the computation of Rate Distortion Optimization. Both the projected vectors and corresponding predictors...
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...
Recently, with the more extensive deployment of Wireless Local Area Networks (WLAN), and the growing population of mobile users, the unstable handover problem in wireless network services receives more and more attention. Since users expect the continuity of services while roaming, IEEE 802 family defines the standard IEEE 802.11r (Fast BSS Transition) to reduce the interrupted time of services to...
