| 摘 要： | 在误码发生严重的信道中进行视频通信,要求解码器具有强的错误检测定位和错误隐藏能力.传统的基于语法(Syntax)的检测方法低的检测率和定位率极大地影响了错误隐藏的效果.通过借助数字水印技术,将改进的迫偶标识法(FEW)应用到H.264编解码系统,用来错误检测和定位,并在H.264的JM 86平台上进行了试验.结果表明,在同等应用环境下,与传统的基于语法的检测方法相比,该方案不但切实可行,而且错误检测率和定位率均有较大提高.

| Abstract: | In video transmission over not-perfect channels where compressed video streams are highly sensitive to packet loss and bit errors,effective Error Detection(ED) and Error Concealment(EC) capability are strongly demanded for decoder.Traditional syntax-based ED technique weakens the effect of EC greatly.In this paper,an embedded watermarking ED scheme-the improved Force Even Watermarking(FEW) for decoder is proposed and a simulation test is done on the JM86 platform of H.264.Compared with the syntax-based ED technique,this new scheme is more practical and efficient. |
