Abstract

Video transmission plays an important role in multimedia communication. Due to transmission error; robust video transmission has become increasingly important in providing better quality of services. Based on our proposed novel adaptive estimation scheme, this paper presents an efficient hybrid error concealment algorithm for robust video transmission. Using the information of neighboring macroblocks (MBs) of the corrupted MBs, the corrupted MBs are first classified into three types. According to the type of the corrupted MB, our proposed adaptive estimation scheme could adopt the Bezier surface estimation, the first-order plane estimation, or the centroid of major cluster estimation to conceal the corrupted MB efficiently. Based on six testing video sequences, experimental results demonstrate that our proposed hybrid error concealment algorithm can improve the video quality and the execution-time performance over different loss rates.
