Overlapped motion compensation for video coding

A device for coding video data, the device comprising:

• a memory configured to store the video data;
• and
• a video coder in communication with the memory, wherein the video coder is configured to:
• store a first block of video data in the memory, wherein the first block of video data is a sub-block of a prediction unit;
• store one or more blocks of video data that neighbor the first block of video data in the memory;
• determine motion information of at least one of the one or more blocks of video data that neighbor the first block of video data;
• and
• code, using overlapped block motion compensation, the first block of video data based at least in part on the motion information of the at least one of the one or more blocks that neighbor the first block of video data.

An apparatus for coding video data, the apparatus comprising:

• means for receiving a first block of video data, wherein the first block of video data is a sub-block of a prediction unit;
• means for receiving one or more blocks of video data that neighbor the first block of video data;
• means for determining motion information of at least one of the one or more blocks of video data that neighbor the first block of video data;
• and
• means for coding, using overlapped block motion compensation, the first block of video data based at least in part on the motion information of the at least one of the one or more blocks that neighbor the first block of video data.

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

• store a first block of video data in a memory, wherein the first block of video data is a sub-block of a prediction unit;
• store one or more blocks of video data that neighbor the first block of video data in the memory;
• determine motion information of at least one of the one or more blocks of video data that neighbor the first block of video data;
• and
• code, using overlapped block motion compensation, the first block of video data based at least in part on the motion information of the at least one of the one or more blocks that neighbor the first block of video data.
