摘要

提出了一种有效的基于cdma2000(或UMTS)空中接口的H.264/AVC视频流错误隐藏方法。所提出的混合错误隐藏方法根据丢失的宏块是内编码还是间编码，是属于背景还是前景，进行选择性错误隐藏。结果表明，在H.264/AVC的FMO编码模式下，在H.264/AVC测试模型中，该方法比内置算法的PSNR增益提高了1.2 dB。此外，该算法比其他传统的错误隐藏算法具有更好的PSNR

Hybrid error concealment method for H.264/AVC

This paper presents an effective error concealment method for error-corrupted H.264/AVC video bitstreams over cdma2000 (or UMTS) air interface. The proposed hybrid error concealment method performs selective error concealment depending on whether a lost macroblock is intra-coded or inter-coded and whether it belongs to background or foreground. It is shown that under FMO coding mode of H.264/AVC, the proposed method increases PSNR gain up to 1.2 dB compared to built-in algorithm in the H.264/AVC test model. In addition, the proposed algorithm shows better PSNR than other conventional error concealment algorithms
