HANDLING OF MULTIPLE PICTURE SIZE AND CONFORMANCE WINDOWS FOR REFERENCE PICTURE RESAMPLING IN VIDEO CODING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18458815 titled 'HANDLING OF MULTIPLE PICTURE SIZE AND CONFORMANCE WINDOWS FOR REFERENCE PICTURE RESAMPLING IN VIDEO CODING

Simplified Explanation

The patent application describes a method of decoding images that involves receiving two sets of picture parameters, which have the same values for picture width and height. These parameters include a conformance window, which is then applied to the current picture being decoded.

  • The method involves receiving two sets of picture parameters.
  • The sets of parameters refer to the same sequence parameter set.
  • The picture width and height values are the same in both sets.
  • Both sets have the same values for the conformance window.
  • The conformance window is applied to the current picture being decoded.

Potential Applications:

  • Video decoding systems
  • Image processing applications
  • Multimedia streaming platforms

Problems Solved:

  • Ensures that the conformance window is correctly applied to the current picture during decoding.
  • Provides a method for handling picture parameters with the same values for picture width and height.

Benefits:

  • Improved accuracy in decoding images.
  • Consistent application of the conformance window.
  • Enhanced visual quality of decoded pictures.


Original Abstract Submitted

A method of decoding includes receiving a first picture parameter set and a second picture parameter set each referring to same sequence parameter set, the first picture parameter set and the second picture parameter set having same values of a conformance window when the first picture parameter set and the second picture parameter set have same values of picture width and picture height, and applying the conformance window to a current picture corresponding to the first picture parameter set or the second picture parameter set.
