Description
7.4.12.11 includes a definition of sb_coded_flag as:
sb_coded_flag[ xS ][ yS ] specifies the following for the subblock at location ( xS, yS ) within the current transform block, where a subblock is an array of transform coefficient levels:
When sb_coded_flag[ xS ][ yS ] is equal to 0, all transform coefficient levels of the subblock at location ( xS, yS ) are inferred to be equal to 0.
When sb_coded_flag[ xS ][ yS ] is not present, it is inferred to be equal to 1
This definition seems to be lacking how many coefficients are found in a sub-block. Although the 7.3.11.11 process says how to derive "numSbCoeff", I don't believe anything in the text explicitly tells you that numSbCoeff defines the number of sub-block coefficients.
