METHOD FOR SIGNALING OF REFERENCE PICTURE RESAMPLING WITH RESAMPLING PICTURE SIZE INDICATION IN VIDEO BITSTREAM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18431652 titled 'METHOD FOR SIGNALING OF REFERENCE PICTURE RESAMPLING WITH RESAMPLING PICTURE SIZE INDICATION IN VIDEO BITSTREAM
Simplified Explanation
The patent application describes a method, device, and computer-readable medium for decoding an encoded video bitstream using at least one processor. The process involves determining whether a conformance window is used for reference picture resampling, signaling a resampling picture size if necessary, determining a resampling ratio based on the resampling picture size or output picture size, and performing reference picture resampling on a current picture using the resampling ratio.
- Obtaining a flag indicating the use of a conformance window for reference picture resampling
- Determining if a resampling picture size is signaled
- Calculating a resampling ratio based on the resampling picture size or output picture size
- Performing reference picture resampling on a current picture
