Method of sub-PU syntax signaling and illumination compensation for 3D and multi-view video coding

An apparatus for three-dimensional or multi-view video encoding or decoding of video data, the apparatus comprising:

• a memory;
• one or more electronic circuits configured to:
• receive input data associated with a current PU (prediction unit);
• signal or parse a first syntax element associated with a texture sub-PU size only for texture video data, wherein the first syntax element corresponds to IVMP (inter-view motion prediction);
• signal or parse a second syntax element associated with a depth sub-PU size only for depth video data, wherein the second syntax element corresponds to MPI (motion parameter inheritance);
• if the current PU is a texture PU:
• locate reference texture sub-PUs in a reference view corresponding to texture sub-PUs partitioned from the current PU according to the texture sub-PU size;
• identify first motion information associated with the reference texture sub-PUs;
• and
• encode or decode the texture sub-PUs according to texture multi-candidate motion prediction including IVMP (inter-view motion prediction) using the first motion information;
• if the current PU is a depth PU:
• locate co-located texture sub-PUs in the reference view corresponding to depth sub-PUs partitioned from the current PU according to the depth sub-PU size;
• identify second motion information associated with the co-located texture sub-PUs;
• and
• encode or decode the depth sub-PUs according to depth multi-candidate motion prediction including MPI (motion parameter inheritance) using the second motion information.

A non-transitory, machine readable media comprising machine readable code configured to perform three-dimensional or multi-view video encoding or decoding of video data when executed by one or more processors, the machine readable code configured to cause the one or more processors to:

• receive input data associated with a current PU (prediction unit);
• signal or parse a first syntax element associated with a texture sub-PU size only for texture video data, wherein the first syntax element corresponds to IVMP (inter-view motion prediction;
• signal or parse a second syntax element associated with a depth sub-PU size only for depth video data, wherein the second syntax element corresponds to MPI (motion parameter inheritance);
• if the current PU is a texture PU:
• locate reference texture sub-PUs in a reference view corresponding to texture sub-PUs partitioned from the current PU according to the texture sub-PU size;
• identify first motion information associated with the reference texture sub-PUs;
• and
• encode or decode the texture sub-PUs according to texture multi-candidate motion prediction including IVMP (inter-view motion prediction) using the first motion information;
• if the current PU is a depth PU:
• locate co-located texture sub-PUs in the reference view corresponding to depth sub-PUs partitioned from the current PU according to the depth sub-PU size;
• identify second motion information associated with the co-located texture sub-PUs;
• and
• encode or decode the depth sub-PUs according to depth multi-candidate motion prediction including MPI (motion parameter inheritance) using the second motion information.
