1222	Error in semantics of sig_coeff_flag	jonathang		"There appears to be an error in the integration of the suggested text in JVET-S0215 (aspect 2).

In the second set of semantics rules for sig_coeff_flag, ie: 
{{{
– Otherwise (transform_skip_flag[ x0 ][ y0 ][ cIdx ] is equal to 1 and sh_ts_residual_coding_disabled_flag is equal to 0), the following applies:
    – If all of the following conditions are true, sig_coeff_flag[ xC ][ yC ] is inferred to be equal to 1:
        – ( xC & ( (1  <<  log2SbW ) − 1 ), yC & ( (1  <<  log2SbH ) − 1 ) ) is equal to ( (1  <<  log2SbW ) − 1, (1  <<  log2SbH ) − 1 ).
        – inferSbDcSigCoeffFlag is equal to 1.
        – sb_coded_flag[ xS ][ yS ] is equal to 1.
}}}

the second condition should be corrected from
{{{
–	inferSbDcSigCoeffFlag is equal to 1
}}}
to
{{{
–	inferSbSigCoeffFlag is equal to 1
}}}

The inferSbDcSigCoeffFlag variable is not used in residual_ts_coding."	defect	closed	minor		spec		fixed		ksuehring bbross XiangLi fbossen jvet@…
