Abstract
A data compression system in which decorrelated data is fed to an entropy encoder (20) in batches having an internal monotonic decrease in average information content from start to end. This results in longer zero runs and more rapid attainment of end of block codes. A data sequencing circuit (18) comprising nested inter-sub band (60) and intra-sub band (72) counters for use with sub band filtered video data is also described.
