無差錯幀 的英文怎麼說
中文拼音 [wúchācuòzhèng]
無差錯幀
英文
error free frame-
In packet based wireless video communications, when best band distribution, not only source distortion should be considered, but also channel distortion caused by channel errors. the existing macroblock - layer rate control schemes calculates quantization parameters of all macroblocks ( mb ) in a frame in a raster scan order, and then encodes the mbs in the same order. actually, the quantization distortion is heavily dependent upon the coding order of mbs
在基於包的無線視頻傳輸中,最佳帶寬分配時,不僅要考慮信源編碼失真,也要考慮由於通道差錯引起的通道失真;已有的宏塊層碼率控制演算法以矩陣掃描的順序計算一幀中所有宏塊的量化參數,事實上量化失真與宏塊的編碼順序有很大關系,改變宏塊的編碼順序,使復雜的宏塊分配到更多的比特數,顯然能大大提高編碼效率。Considering the stability and continuity of face region, and the error propagation effect due to the high error rate in wireless channels, the intra - refresh method is used. the redundant data is not too much owing to the continuity, and the error propagation effect can be stopped accordingly
由於視頻中出現的人臉具有穩定性,連續性等特點,同時考慮到無線移動通道由於誤碼率高而引起差錯傳播問題,所以採用幀內編碼宏塊刷新的方法。
