Figure 1From: Dynamic voltage and frequency scaling over delay-constrained mobile multimedia service using approximated relative complexity estimationThe structures of GOP usually used in H.264/AVC with complexity estimation order. (a) Non-dyadic hierarchical structure. (b) Dyadic hierarchical structure. The round dot dashed line shows the reference structure for the I frame, the long dashed line shows the reference structure for the P frame, and the solid dashed line shows the reference structure for the B frame.Back to article page
