*This abstract for appeared for patent application  number 18208070 Titled 'IMAGE/VIDEO CODING METHOD AND APPARATUS BASED ON INTER PREDICTION'

==Simplified Explanation==

This abstract describes a method for decoding videos using a video decoding apparatus. The method involves parsing a flag for weighted prediction from a bitstream, parsing a prediction weighted table syntax from the bitstream based on the flag, generating prediction samples by performing weighted prediction on a current block within a current picture using the prediction weighted table syntax, and generating reconstructed samples for the current block based on the prediction samples. The prediction weighted table syntax can be parsed from either the picture header or slice header of the bitstream, depending on the value of the flag.


==Original Abstract Submitted==

A video decoding method performed by a video decoding apparatus, according to the present document, comprises the steps of: parsing a flag for weighted prediction from a bitstream; parsing a prediction weighted table syntax from the bitstream on the basis of the flag; generating prediction samples by performing weighted prediction on a current block within a current picture on the basis of the prediction weighted table syntax; and generating reconstructed samples for the current block on the basis of the prediction samples, wherein the prediction weighted table syntax may be parsed from a picture header or slice header of the bitstream on the basis of a value of the flag.
