中文摘要	AVS增强档次中两阶段MBAFF(Macroblock Adaptive Frame/Field coding)技术的宏块编码顺序的不规则性导致了宏块定位复杂度的增加。为此,提出一个有效的AVS两阶段MBAFF宏块定位结构,首先采用了宏块对组技术,并优化了帧/场模式标志的存储结构。实验结果表明,该结构用很小的硬件代价,可节省约15%的存储器访问次数和处理时间。; Two-stage Macroblock Adaptive Frame/Field coding (MBAFF) is adopted in the advanced profile of Audio Video Coding Standard (AVS), with which the macroblocks are coded in two-stage in an irregular order, and such irregularity brings on the complexity problem of MB positioning. This paper proposes an efficient architecture of MB positioning for the two-stage MBAFF in AVS. In the proposed design, a Macroblock Pair Group (MBPG) scheme and an optimized memory organization scheme for storing frame/filed modes are presented. Simulation results show that a saving of about 15% of memory access and processing time can be achieved, at very little hardware cost.
