Inter-view residual prediction in 3d video coding

A video coding device comprising a video coder configured to:

• determine a disparity vector for a current block of video data in a current view based on depth information for the current block, wherein the disparity vector indicates a location of a residual reference block of video data in a reference view relative to the current block;
• determine a value of a coded block flag for the residual reference block;
• and
• code the current block using inter-view residual prediction only when the value of the coded block flag indicates that the residual reference block includes at least one non-zero coefficient.

A video coding device comprising:

• means for determining a disparity vector for a current block of video data in a current view based on depth information for the current block, wherein the disparity vector indicates a location of a residual reference block of video data in a reference view relative to the current block;
• means for determining a value of a coded block flag for the residual reference block;
• and
• means for coding the current block using inter-view residual prediction only when the value of the coded block flag indicates that the residual reference block includes at least one non-zero coefficient.

A computer-readable storage medium having stored thereon instructions that when executed cause one or more processors to:

• determine a disparity vector for a current block of video data in a current view based on depth information for the current block, wherein the disparity vector indicates a location of a residual reference block of video data in a reference view relative to the current block;
• determine a value of a coded block flag for the residual reference block;
• and
• code the current block using inter-view residual prediction only when the value of the coded block flag indicates that the residual reference block includes at least one non-zero coefficient.
