Abstract

A method and computing device for video encoding are provided. A computing device performs a method of decoding video data by determining a co-located picture of a current coding unit; locating a spatial adjacent block of the current coding unit corresponding to the co-located picture; determining a motion shift vector of the current coding unit from one or more motion vectors associated with the spatially neighboring block according to a predefined fixed order; and reconstructing a sub-block-based temporal motion vector of a corresponding sub-block of the plurality of sub-blocks in the current coding unit from the corresponding sub-block in the co-located picture based on the motion shift vector.

Description

[0001] This application is a divisional application of the invention application with the application number 202080036321.0, the application date is June 5, 2020, and the title is "Sub-block Temporal Motion Vector Prediction for Video Codec". technical field [0002] The present application relates generally to video data encoding and decoding, and in particular, to methods and systems for sub-block motion vector prediction during video data encoding and decoding. Background technique [0003] Various electronic devices (such as digital televisions, laptop or desktop computers, tablet computers, digital cameras, digital recording devices, digital media players, video game consoles, smartphones, video teleconferencing devices, video streaming devices, etc.) Digital video is supported. Electronic devices are implemented by implementing MPEG-4, ITU-T H.263, ITU-T H.264 / MPEG-4, Part 10, Advanced Video Coding (AVC), High Efficiency Video Coding (HEVC) and Versatile Video Coding (...
