  • This abstract for appeared for patent application number 18209926 Titled 'IMAGE ENCODING/DECODING METHOD AND DEVICE USING WEIGHTED PREDICTION, AND METHOD FOR TRANSMITTING BITSTREAM'

Simplified Explanation

The abstract describes a method and apparatus for encoding and decoding images. The decoding method involves extracting weight information from a bitstream, which specifies the importance of a reference sample. This weight information is then used to perform inter prediction and decode the current block. The weight information is obtained by parsing the weight parameter syntax structure, which includes obtaining the number of weight information and extracting the weight information based on this number.


Original Abstract Submitted

An image encoding/decoding method and apparatus are provided. An image decoding method performed by an image decoding apparatus may comprise parsing weight information specifying a weight for a reference sample from a bitstream according to a weight parameter syntax structure, and decoding a current block by performing inter prediction based on the weight information. The parsing according to the weight parameter syntax structure may comprise obtaining weight number information specifying the number of weight information obtained from the bitstream according to the weight parameter syntax structure and obtaining weight information from the weight parameter syntax structure based on the weight number information.
