Description
Summary:碩士 === 國立臺南大學 === 資訊工程學系碩士班 === 100 === With the rapid advances in multimedia coding and networking technique, provide a variety of multimedia applications on wireless network. However, packet loss of transiting H.264/AVC videos on wireless network is normally inevitable, it lead to the information of the subsequent frame error propagation and the decline of watch quality. In order to solve the problem of packet loss, this paper proposes an estimation method based on the H.264/AVC codec smallest unit of encoding and decoding. Provide to unequal loss protection on basic of the group of picture and allocate forward error correction. For this reason, we propses the estimation method which is Frame Macroblock Error Propagation Index to determine the importance of frame. Moreover, the impact of the overall video quality of an importance index that is according to FMEPI to allocate a different number of FEC packets. Finally, it was found from the simulation results that FMEPI method has better video quality than other methods.
