Abstract
A video encoder is configured to encode a bit stream including a coded picture having a first contiguous region and a second contiguous region, the first contiguous region containing common motion, the second contiguous region containing local motion. The encoded bitstream is provided to a decoder which is configured to decode the first contiguous region of the coded picture to reconstruct the common motion by utilizing a motion model common to all of the coding blocks in the first region. A merge candidate list is selectively created and a merge candidate is selected to decode the first region based on the common motion model. The second contiguous region is decoded using individual motion information for each coding block in the second contiguous region.
