Patent number: 11616970Abstract: A motion vector refinement apparatus includes a first storage device, a motion vector predictor (MVP) derivation circuit, and a decoder side motion vector refinement (DMVR) circuit. The MVP derivation circuit derives a first MVP for a current block, stores the first MVP into the first storage device, and performs a new task. The DMVR circuit performs a DMVR operation to derive a first motion vector difference (MVD) for the first MVP. The MVP derivation circuit starts performing the new task before the DMVR circuit finishes deriving the first MVD for the first MVP.Type: GrantFiled: January 25, 2022Date of Patent: March 28, 2023Assignee: MEDIATEK INC.Inventors: Chi-Hung Chen, Cheng-Han Li, Hong-Cheng Lin

Patent number: 11025947Abstract: A motion vector (MV) projection method includes generating motion field motion vectors (MFMVs) for a first portion of a current frame by applying MV projection to MVs of a portion of each of reference frames and storing the MFMVs of the first portion of the current frame into an MFMV buffer, and generating MFMVs for a second portion of the current frame by applying MV projection to MVs of a portion of each of the reference frames and storing the MFMVs of the second portion of the current frame into the MFMV buffer. The second portion does not overlap the first portion. Before generating the MFMVs for the second portion of the current frame is done, at least one of the MFMVs of the first portion is read from the MFMV buffer and involved in motion vector determination of at least one coding block included in the first portion.Type: GrantFiled: November 26, 2019Date of Patent: June 1, 2021Assignee: MEDIATEK INC.Inventors: Yung-Chang Chang, Chia-Yun Cheng, Cheng-Han Li, Hong-Cheng Lin, Chi-Hung Chen

Publication number: 20190075312Abstract: A video decoding method is used for decoding a multi-plane video bitstream. The multi-plane video bitstream includes a first video subset bitstream corresponding to a fundamental plane (FP) and at least one second video subset bitstream corresponding to at least one augmented plane (AP). The video decoding method includes decoding the first video subset bitstream, decoding the at least one second video subset bitstream, and performing resampling of one decoded FP frame to generate one resampled frame. Decoding the first video subset bitstream includes performing decoding of a first FP frame to generate a first decoded FP frame. Decoding the at least one second video subset bitstream includes performing decoding of a first AP frame to generate a first decoded AP frame. A processing time of performing decoding of the first FP frame overlaps a processing time of performing resampling of said one decoded FP frame.Type: ApplicationFiled: September 6, 2018Publication date: March 7, 2019Inventors: Yung-Chang Chang, Chia-Yun Cheng, Chih-Ming Wang, Meng-Jye Hu, Cheng-Han Li

Publication number: 20190037223Abstract: A method and apparatus of scalable video coding using Inter prediction mode for a video coding system are disclosed, where video data being coded comprise BP (Basic Resolution Pass) pictures and UP (Upgrade Resolution Pass) pictures. In one embodiment according to the present invention, the method comprises receiving information associated with input data corresponding to a target block in a target UP picture. When the target block is Inter coded according to a current MV (motion vector) and uses a collocated BP picture as one reference picture, one or more BP MVs (motion vectors) of the collocated BP picture are scaled to generate one or more RCP (resolution change processing) MVs. The current MV of the target block is encoded or decoded using an UP MV predictor derived based on one or more temporal MVPs including said one or more RCP MVs.Type: ApplicationFiled: July 24, 2018Publication date: January 31, 2019Inventors: Yung-Chang CHANG, Chia-Yun CHENG, Cheng-Han LI
