Abstract:
A video coder can be configured to perform texture first coding for a first texture view, a first depth view, a second texture view, and a second depth view; for a macroblock of the second texture view, locate a depth block of the first depth view that corresponds to the macroblock; based on at least one depth value of the depth block, derive a disparity vector for the macroblock; code a first sub-block of the macroblock based on the derived disparity vector; and, code a second sub-block of the macroblock based on the derived disparity vector.
