IMAGE/VIDEO ENCODING/DECODING METHOD AND APPARATUS USING SAME - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18215776 Titled 'IMAGE/VIDEO ENCODING/DECODING METHOD AND APPARATUS USING SAME'
Simplified Explanation
This abstract describes a method for decoding videos using a video decoding apparatus. The method involves parsing a prediction weighted table syntax from a bitstream, which contains information about weighted reference pictures in a reference picture list. The method then derives a weighting factor-related flag based on this information. Using this flag, the method performs weighted prediction on a current block to obtain prediction samples. The method also generates residual samples from residual information in the bitstream. Finally, the method reconstructs a current picture using the prediction samples and the residual samples. The prediction weighted table syntax is parsed from the picture header of the bitstream.
Original Abstract Submitted
A video decoding method performed by a video decoding apparatus according to the present document may comprise the steps of: parsing a prediction weighted table syntax from a bitstream; parsing number information about weighted reference pictures in a reference picture list from the prediction weighted table syntax; deriving a weighting factor-related flag about the reference picture list on the basis of the number information; performing weighted prediction on a current block on the basis of the weighting factor-related flag so as to derive prediction samples of the current block; generating residual samples on the basis of residual information obtained from the bitstream; and reconstructing a current picture on the basis of the prediction samples and the residual samples, wherein the prediction weighted table syntax is parsed from a picture header of the bitstream.
