Description

“alf_ctb_cc_cb_idc[ xCtb >> CtbLog2SizeY ][ yCtb >> CtbLog2SizeY ] equal to 0 specifies that the cross-component filter is not applied to the coding tree block of the Cb colour component at luma location ( xCtb, yCtb ). When alf_cc_cb_idc[ xCtb >> CtbLog2SizeY ][ yCtb >> CtbLog2SizeY ] not equal to 0, alf_cc_cb_idc[ xCtb >> CtbLog2SizeY ][ yCtb >> CtbLog2SizeY ] − 1 specifies the filter set index of the cross-component filter applied to the coding tree block of the Cb colour component at luma location ( xCtb, yCtb ).”

Should be replaced by:

“alf_ctb_cc_cb_idc[ xCtb >> CtbLog2SizeY ][ yCtb >> CtbLog2SizeY ] equal to 0 specifies that the cross-component filter is not applied to the coding tree block of the Cb colour component at luma location ( xCtb, yCtb ). When alf_ctb_cc_cb_idc[ xCtb >> CtbLog2SizeY ][ yCtb >> CtbLog2SizeY ] not equal to 0, alf_ctb_cc_cb_idc[ xCtb >> CtbLog2SizeY ][ yCtb >> CtbLog2SizeY ] − 1 specifies the filter set index of the cross-component filter applied to the coding tree block of the Cb colour component at luma location ( xCtb, yCtb ).”

Thanks! Good catch!

Also, "is" is missing in the condition starting with "When".

And, all these changes should also be applied to the semantics of alf_ctb_cc_cr_idc[ xCtb >> CtbLog2SizeY ][ yCtb >> CtbLog2SizeY ].
