(taking into account ticket #721) According to entropy_coding_sync_enabled_flag definition : ""'''entropy_coding_sync_enabled_flag''' equal to 1 specifies that a specific synchronization process for context variables is invoked before decoding the first coding tree block of a row of coding tree blocks in each tile..."" the condition should be : The current quantization group is the first quantization group in a coding tree block row '''of a tile''' and entropy_coding_sync_enabled_flag is equal to 1.",enhancement,closed,minor,D10,Text,D10 (L1003) v2,duplicate,quantization,bbross wjhan jct-vc@…
