Description
In 8.8.3.6.3 Decision process for chroma block edges, the following typos should be fixed.
The value of the variable tC′ is determined as specified in Table 43 based on the chroma quantization parameter Q derived as follows:
sliceTcOffsetDiv2 = ( cIdx = = 1 ? slice_cb_tc_offset_div2 : slice_cr_betatc_offset_div2 )
Q = Clip3( 0, 65, QpC + 2 * ( bS − 1 ) + ( sliceTcOffsetDiv2 << 1 ) ) (1364)
where slice_cb_tc_offset_div2 and slice_cr_betatc_offset_div2 are the values of the syntax elements slice_cb_tc_offset_div2 and slice_cr_betatc_offset_div2, respectivelyl, for the slice that contains sample q0,0.
