codec error
解釋
出現編碼錯誤-
Research of error resilience technology for video communication based on h. 263 codec major : signal and information processing data : author : meng yan signature : tutor : zhang erhu liu shichang signature : abstract the reconstructed image quality can be degraded substantially by errors during the transmitting over the communication channel, especially when the video is compressed by temporal and spatial coding ways, which leads to error propagation in frame sequence, so the error resilience procedure should be performed to improve the reconstruction quality
由於通信系統的通道不可避免的存在噪聲，傳輸數據流必然存在誤碼。對于h . 26x的視頻編碼流，由於空域和時域的壓縮方法以及熵編碼方法的應用，即使是一個比特的錯誤，常會影響一個區域的圖像不能正確解碼，同時錯誤的圖像還會擴散影響后續數幀圖像。因此有必要在標準解碼程序的基礎上，添加容錯功能。 -
So video optimized error resilience techniques are necessary due to the nature of video codec
因此視頻數據需要較優的錯誤恢復技術來克服視頻編解碼的先天缺陷。 -
The main innovations of this dissertation are summarized as follows : bring forward respectively coding the magnitude and sign of the predictive error of ll subband, which can combined some existing wavelet image codec to improve result
在許多改進和創新下，提出的兩種嵌入式圖像壓縮演算法相比于各種流行的小波編碼器，取得了很好的性能，有了較大的突破。
