Deltaq is at superblock granularity, whereas "AQ" uses segment support which is down to 4x4 granularity. The two bitstream features are sorta redundant but their coding is optimized for different uses - Deltaq was designed for sub-frame rate targeting, and segments are more for mbtree/psy purposes.
