摘要
视频码流在ATM传输网络中 ,一般存在 1 0 %以下的码流丢失或错误 ,如何检测这些错误是视频领域研究的重要课题之一。本文从分析图像错误情况出发 ,通过五步错误检测 ,首次系统提出了MPEG -2图像错误的检测方法 ,通过实验验证 。
There usually exist some errors (ranging less than 10% of the bit-stream) in the bit-stream of the ATM transmission. How to detect these errors has become one of the important concerns in the field of video-research. In this paper, a systemic error-detecting method is firstly present which characterizes with five-steps based on the error analyzing. The proposed approach is tested by experiments and good result is gained.
