宏块层 meaning in English
macroblock layer
Examples
- This article discusses the modified frame rate control algorithm based on tmn11 and the modified macroblock - layer rate control algorithm
论文重点讨论了无线网络中基于tmn11的改进型帧率控制算法及改进型宏块层码率控制算法。 - 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
在宏块层利用了现有mad值表示宏块复杂度,进一步根据宏块的复杂度阈值自适应地调整量化参数qp ,对复杂度高的宏块采用较小的qp值,进行精细量化;对复杂度低的qp值采用较大的qp值,以节约比特数。 - 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
在基于包的无线视频传输中，最佳带宽分配时，不仅要考虑信源编码失真，也要考虑由于信道差错引起的信道失真；已有的宏块层码率控制算法以矩阵扫描的顺序计算一帧中所有宏块的量化参数，事实上量化失真与宏块的编码顺序有很大关系，改变宏块的编码顺序，使复杂的宏块分配到更多的比特数，显然能大大提高编码效率。
