Signaling of multiview video plus depth content with a block-level 4-component structure

A device for decoding data, comprising a video decoder configured to:

• receive a coded block unit indicative of pixels of one or more texture components and a depth map component;
• receive an attribute of the depth map component relative to the one or more texture components, wherein the value for the attribute for the depth map component is different from the value of a corresponding attribute for the one or more texture components;
• and
• determine a portion of an image representing a view of three dimensional video data from the one or more texture components, the depth map component, and the attribute.

A computer program product comprising a computer-readable storage medium having stored thereon instructions that, when executed, cause a processor of a video decoding device to:

• receive a coded block unit indicative of pixels of one or more texture components and a depth map component;
• receive an attribute of the depth map component relative to the one or more texture components, wherein the value for the attribute for the depth map component is different from the value of a corresponding attribute for the one or more texture components;
• and
• determine a portion of an image representing a view of three dimensional video data from the one or more texture components, the depth map component, and the attribute.

A device for processing video data, comprising:

• means for receiving a coded block unit indicative of pixels of one or more texture components and a depth map component;
• means for receiving an attribute of the depth map component relative to the one or more texture components, wherein the value for the attribute for the depth map component is different from the value of a corresponding attribute for the one or more texture components;

A method of processing video data, the method comprising:

• receiving pixels of one or more texture components from at least a portion of an image representing a view of three dimensional video data;
• receiving a depth map component for at least the portion of the image;
• coding a block unit indicative of the pixels of the one or more texture components for a portion of the image and the depth map component, wherein coding comprises coding the depth map component relative to at least one of the texture components;
• and
• signaling an attribute of the depth map component relative to the one or more texture components, wherein the value for the attribute for the depth map component is different from the value of the one or more texture components.
