VIDEO PICTURE PREDICTION METHOD AND APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240187571 titled 'VIDEO PICTURE PREDICTION METHOD AND APPARATUS

Simplified Explanation

The patent application describes a method and apparatus for predicting video pictures by determining the maximum length of a candidate motion vector list corresponding to a subblock merge mode.

• Parsing a first indicator from a bitstream.
• If the first indicator indicates the use of an affine mode for inter-prediction, parsing a second indicator from the bitstream to determine the maximum length of a candidate motion vector list.
• Constructing the first candidate motion vector list for the to-be-processed block when a subblock merge prediction mode is used.
• Determining the maximum length of the first candidate motion vector list based on the second indicator.
