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。 -

According to the complexity threshold, we auto - adaptatively adjust the qp. we use the smaller qp to quantify the more complicated macroblock and use the bigger qp to quantify the less complicated macroblok. the proposed algorithm can improve the h. 264 standard algorithm by a rate control algorithm on macroblock layer
在宏塊層利用了現有mad值表示宏塊復雜度，進一步根據宏塊的復雜度閾值自適應地調整量化參數qp ，對復雜度高的宏塊採用較小的qp值，進行精細量化;對復雜度低的qp值採用較大的qp值，以節約比特數。
