METHOD FOR ENCODING AND DECODING MOTION INFORMATION, AND APPARATUS FOR ENCODING AND DECODING MOTION INFORMATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18502696 titled 'METHOD FOR ENCODING AND DECODING MOTION INFORMATION, AND APPARATUS FOR ENCODING AND DECODING MOTION INFORMATION
Simplified Explanation
The video decoding method described in the patent application involves determining a prediction mode for a current block, which can be either a skip mode or a merge mode. When using a motion vector and a merge motion vector difference from a merge candidate list for the current block, merge candidate information is obtained by entropy encoding a bitstream with context information. A base motion vector is then determined from the merge candidate list, and the motion vector of the current block is determined using the merge motion vector difference and the base motion vector.
- Determining prediction mode of current block as skip mode or merge mode
- Obtaining merge candidate information from merge candidate list using entropy encoding
- Determining base motion vector from merge candidate list
- Using merge motion vector difference and direction index to determine motion vector of current block

Original Abstract Submitted
Provided is a video decoding method including: determining a prediction mode of a current block to be one of a skip mode and a merge mode; when a motion vector, which is determined from a merge candidate list of the current block, and a merge motion vector difference are to be used, obtaining merge candidate information indicating one candidate in the merge candidate list by performing entropy encoding on a bitstream by applying one piece of context information; determining a base motion vector from one candidate determined from the merge candidate list, based on the merge candidate information; and determining a motion vector of the current block by using a distance index of a merge motion vector difference of the current block and a direction index of the merge motion vector difference to use the base motion vector and the merge motion vector difference.
