Japan, Sept. 16 -- INTERDIGITAL VC HOLDINGS INC has got intellectual property rights for 'SUB-BLOCK MOTION DERIVATION AND DECODER-SIDE MOTION VECTOR REFINEMENT FOR MERGE MODE.' Other related details are as follows:
Application Number: JP,2025-135257
Category (FI): H04N19/577,H04N19/137,H04N19/105,H04N19/513,H04N19/109,H04N19/176,H04N19/52
Stage: PROBLEM TO BE SOLVED: To provide systems, methods, and means for sub-block motion derivation and motion vector refinement for a new merge mode.SOLUTION: Video data may be coded (encoded and/or decoded). A collocated picture for a current slice of the video data may be identified. The current slice may include one or more coding units (CUs). One or more neighboring CUs may be identified for a current CU. A neighboring CU (e.g., each neighboring CU) may correspond to a reference picture. A (e.g., one) neighboring CU may be selected to be a candidate neighboring CU based on the reference pictures and the collocated picture. A motion vector (MV) (e.g., collocated MV) may be identified from the collocated picture based on an MV (e.g., a reference MV) of the candidate neighboring CU. The current CU may be coded (encoded and/or decoded) using the collocated MV.SELECTED DRAWING: Figure 15 (Grant)
