VIDEO DECODING METHOD AND APPARATUS, AND VIDEO ENCODING METHOD AND APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240380900 titled 'VIDEO DECODING METHOD AND APPARATUS, AND VIDEO ENCODING METHOD AND APPARATUS

Simplified Explanation:

This patent application describes a method and apparatus for determining if a slice containing an adjacent pixel at the upper-left or lower-right side of a current pixel is different from a slice containing the current pixel. If they are different, the value of the adjacent pixel is used to correct the current pixel value through an adaptive loop filter, which is then applied to the current block for encoding/decoding.

• Determines if a slice with an adjacent pixel is different from the current pixel slice
• Corrects the current pixel value using the adjacent pixel value
• Applies an adaptive loop filter to the current pixel
• Encodes/decodes the current block

Key Features and Innovation:

• Method to determine differences between adjacent pixel slices
• Adaptive loop filter for correcting pixel values
• Encoding/decoding process for current block

Potential Applications:

• Video encoding and decoding processes
• Image processing technologies
• Multimedia applications

Problems Solved:

• Enhancing video quality by correcting pixel values
• Improving compression efficiency in video encoding

Benefits:

• Higher quality video output
• More efficient video compression
• Enhanced visual experience for viewers

Commercial Applications:

• Video streaming services
• Video editing software
• Multimedia content creation tools

Prior Art:

Prior art related to this technology may include research on video encoding algorithms, adaptive loop filters, and image processing techniques.

Frequently Updated Research:

Research on video compression techniques, image quality enhancement algorithms, and multimedia data processing may be relevant to this technology.

Questions about Video Encoding and Decoding:

1. How does the method determine if a slice with an adjacent pixel is different from the current pixel slice? 2. What are the potential commercial applications of this technology in the video industry?

Original Abstract Submitted

in a video encoding and decoding process, provided are a method and apparatus for determining whether a slice including an adjacent pixel located at the upper-left or lower-right side of a current pixel from among adjacent pixels used for an adaptive loop filter of the current pixel is different from a slice including the current pixel, when the slice including the adjacent pixel at the upper-left or lower-right location is different from the slice including the current pixel, determining a value of the adjacent pixel located at the upper-left or lower-right side as a value of a closest pixel in a horizontal direction of the adjacent pixel located at the upper-left or lower-right side from among pixels included in the slice including the current pixel, determining an adaptive loop filter including a filter coefficient for the current pixel and the adjacent pixels based on values of the current pixel and the adjacent pixels, correcting the value of the current pixel by using the values of the adjacent pixels, by applying the adaptive loop filter to the current pixel, and encoding/decoding a current block including the current pixel.
