-// AVC Child Kernel (Vertical and horizontal de-block a 4:2:0 MB Y comp)
-//
-// First, de-block vertical edges from left to right.
-// Second, de-block horizontal edge from top to bottom.
-//
-// ***** MBAFF Mode *****
-// This version deblocks top MB first, followed by bottom MB.
-//
-// Need variable CurMB to indicate top MB or bottom MB (CurMB = 0 or 1).
-// We can use BotFieldFlag in BitFields to represent it.
-//
-// Usage:
-// 1) Access control data for top
-// CntrlDataOffsetY + CurMB * Control data block size (64 DWs for CL, 16 DWs for BLC)
-//
-// 2) Load frame/field video data based on flags: FieldModeCurrentMbFlag, FieldModeLeftMbFlag, FieldModeaboveMbFlag,
-//
-// E.g.
-// if (pCntlData->BitField & FieldModeCurrentMbFlag)
-// cur_y = ORIX_CUR.y + CurMB * 1; // Add field vertical offset for bot field MB .
-// else
-// cur_y = ORIX_CUR.y + CurMB * MB_Rows_Y; // Add bottom MB vertical offset for bot MB
-//
