Bug for VSP inheritance in H.8.5.3.2.1.17

Reported by: ewchen Owned by: tech
Priority: minor Component: 3D-HEVC text
Version: 3D-HEVC Draft 2 Keywords:
Cc: tech, jct-3v@…

Description

The subclause is related to the inheritance of VSP mode.
VSP mode can still be inherited from above neighbors as lons as they in the same CTU row.

The reference (software) HTM-9.0 has been implemented correctly for this part but the WD is not updated correctly.

In H.8.5.3.2.1.17,

The variable mergeCandIsVspFlag is derived as specified in the following:
– If N is equal to VSP, mergeCandIsVspFlag is set equal to 1,
– Otherwise, if N is equal to A1, mergeCandIsVspFlag is set equal to VspModeFlag[ xPb − 1 ][ yPb + nPbH − 1 ],
– Otherwise, if N is equal to A0, mergeCandIsVspFlag is set equal to VspModeFlag[ xPb − 1 ][ yPb + nPbH ],
– Otherwise, mergeCandIsVspFlag is set equal to 0.

should be modified as

The variable mergeCandIsVspFlag is derived as specified in the following:
– If N is equal to VSP, mergeCandIsVspFlag is set equal to 1,
– Otherwise, if N is equal to A1, mergeCandIsVspFlag is set equal to VspModeFlag[ xPb − 1 ][ yPb + nPbH − 1 ],
– Otherwise, if N is equal to A0, mergeCandIsVspFlag is set equal to VspModeFlag[ xPb − 1 ][ yPb + nPbH ],
– Otherwise, if N is equal to B0 and ( yN >> Log2CtbSizeY ) is equal to ( yCb >> Log2CtbSizeY ), mergeCandIsVspFlag is set equal to VspModeFlag[ xPb − 1 ][ yPb + nPbH ],
– Otherwise, if N is equal to B1 and ( yN >> Log2CtbSizeY ) is equal to ( yCb >> Log2CtbSizeY ), mergeCandIsVspFlag is set equal to VspModeFlag[ xPb − 1 ][ yPb + nPbH ],
– Otherwise, if N is equal to B2 and ( yN >> Log2CtbSizeY ) is equal to ( yCb >> Log2CtbSizeY ), mergeCandIsVspFlag is set equal to VspModeFlag[ xPb − 1 ][ yPb + nPbH ],
– Otherwise, mergeCandIsVspFlag is set equal to 0.
