video dpcm 中文意思是什麼
-
The extensive use of prediction and variable - length coding in video coding renders compressed bitstreams especially vulnerable to transmission errors and data losses. based on detailed analyses of mc - dpcm / dct mechanism, several error detection, resilience, concealment methods are discussed in this paper
本文在分析mc - dpcm dct壓縮視頻特點的基礎上研究了各種誤碼檢測方法，並詳細討論了編碼端的誤碼容錯、傳輸層差錯控制、解碼端的失真屏蔽以及編碼器和解碼器交互的差錯控制方法。 -
What the part of the principle of video reduced narrates mainly is that there is plentiful temporal redundancy between adjacent frames in a video sequence for their " similarity " and there is a lot of spatial redundancy in each pixel within a frame for their " similarity ", the video is compressed by reducing spatial and temporal and statistical redundancy with the technology of dpcm and dct and huffman encoding
視頻壓縮原理部分介紹了視頻序列的相鄰幀之間的「相似」而存在大量的時間冗餘度，幀內各相鄰象素的「相似」而存在大量的空間冗餘度。通過使用dpcm 、 dct和huffman編碼去除了時間、空間及統計冗餘度，從而實現了視頻的壓縮。
