A inter - frame error concealment algorithm based on motion estimation is proposed in this dissertation, the motion vectors and coding mode can be rebuilt, it can be applied in any frame modes and macroblock modes
本文提出了基於運動估值的幀間預測錯誤隱藏演算法，能對運動矢量和編碼模式的進行有效重建，適應各種情況的幀間錯誤隱藏。77 motion vector : a two - dimensional vector used for inter prediction that provides an offset from the coordinates in the decoded picture to the coordinates in a reference picture
運動矢量：一個二維矢量，用在幀間預測中，提供解碼圖象（中塊）相對于參考圖象（中參考塊）的坐標的偏移量。The new algorithm has three characters : first is that the new algorithm is on the basis of super frame which include 3 continuous simple frames in melp algorithm, the algorithm deal with parameters of a super frame by the mode of the super frame. secondly, two algorithms are introduced for improving vector quantization quality of line spectral frequency ( lsf ) parameter. one is swithed - adaptive inter - frame vector prediction ( sivp ), which can get rid of the correlation between neighboring frames effectively, the other is joint codebook optimization for multi stage vector quantization ( jco - msvq ), which can improve performance of codebook
第二是在製作線譜對參數（ lsf ）矢量量化碼本時，引入了目前提高lsf碼本性能的兩個方法:在利用重點幀對非重點幀作預測時，借鑒自適應幀間矢量量化（ sivp ）去除相關性演算法的優點，提出了以固定矩陣去除相關性的方法，有效的控制了預測后殘差的動態范圍，提高了對殘差矢量量化的精度;採用聯合碼本優化多級矢量量化演算法（ jco - msvq ） ，改良多級矢量量化碼本的性能。
