【摘要】 本文提出了一种应用于H.263视频编码传输的纠错方法,即基于H.263视频解码的错误检测和掩盖算法。这种算法可应用于公共交换电话网(PSTN),Internet或移动信道的视频通信。模拟结果表明,这种纠错方法在不降低编码效率的前提下,使在有噪声干扰的信道上传输图像的质量有显著的改善。更多还原

【Abstract】 This paper presents an error correction method applied in H.263 video coding, which is the H.263 video decode based error check and concealment algorithm. This algorithm can be applied in video communication of Public Switched Telephone Network (PSTN), Internet or mobile channel. It has been found that this error correction method can greatly improve the quality of the images transmitted on channel with noise interference and will not decrease coding efficiency.更多还原
