This scheme firstly determined the operating mode of coded video stream in nal layer according to the current channel state before they were packed . the coded video stream operated under ssm in error - free channel so as to reduce the packing tradeoff and increase the coding efficiency . while in error - prone channel , they operated under dpm combined with improved unequal error protection ( uep ) scheme based on human eyes characteristic in order to elevate their robustness to channel error
該方案中編碼視頻信息在進行打包封裝前，首先根據當前信道狀態信息自適應地確定其在nal層中的工作模式，在無丟包信道中采用單數據片模式以降低編碼視頻流的打包開銷，提高編碼效率；而在丟包信道中采用數據分區模式以提高編碼視頻流對信道誤碼的魯棒性能，同時基于人眼視覺特性，提出了一種改進的uep策略。
One of the common characters between traditional algorithms based on dct image coding is that regardless of the content of the image , they use a fixed size block to process , for example , jpeg , mpeg - 1 / 2 , h . 263 use constant 8 * 8 block mode . the main work of this article is to propose a sequence images compression algorithm that is based on adaptive block dividing and object to the disadvantages of the one based on fixed - size block dividing . the proposed algorithm is an image compression method , which can auto - adjust dct block size ( 8 * 8 or 4 * 4 ) according to the difference of corresponding blocks between two frames of the sequential image and doesn ’ t process any unnecessary data blocks in order to enhance coding efficiency
傳統的基于dct的圖像編碼算法的一個共同特點就是:不管圖像的具體內容,采用固定的塊尺寸進行統一的處理,例如jpeg , mpeg - 1 / 2 , h . 263均采用固定的8 8分塊方式,本文的重點工作是針對這些采用固定的塊尺寸進行統一處理的算法的一些缺點,提出了一種基于自適應分塊的序列圖像壓縮算法,該算法是一種根據序列圖像兩幀間對應塊的差別自動調整dct變換尺寸( 8 8或4 4 ) ,對不必要的數據塊不進行處理,以提高編碼效率的序列圖像壓縮編碼方法,具有較高的編碼效率和較好的壓縮效果,與傳統的采用8 8固定分塊方式的壓縮編碼算法相比,性能有較大幅度的提高,在文中,作者對兩者的壓縮編碼性能進行了分析比較。
