VIDEO CODING APPARATUS, VIDEO CODING METHOD, VIDEO CODING PROGRAM, AND NON-TRANSITORY RECORDING MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18281872 titled 'VIDEO CODING APPARATUS, VIDEO CODING METHOD, VIDEO CODING PROGRAM, AND NON-TRANSITORY RECORDING MEDIUM
The patent application describes an adaptive loop filter that aims to improve compression efficiency while managing implementation costs.
- The adaptive loop filter includes an acquisition unit to gather statistical information on the picture to be coded.
- An allocation unit allocates a single filter set common to multiple blocks in the picture based on the statistical information.
- A filter processing unit executes adaptive loop filter processing on each block using the single filter set.
Potential Applications: - Video compression technology - Image processing applications - Multimedia encoding and decoding systems
Problems Solved: - Enhancing compression efficiency - Managing implementation costs - Improving picture quality in coding processes
Benefits: - Increased compression efficiency - Cost-effective implementation - Enhanced picture quality in coding
Commercial Applications: Title: "Adaptive Loop Filter Technology for Enhanced Compression Efficiency" This technology can be utilized in video streaming services, surveillance systems, and digital media platforms to improve compression efficiency and reduce implementation costs.
Prior Art: There is prior art related to adaptive loop filters in video coding standards such as H.264 and H.265, but this patent application introduces improvements in efficiency and cost-effectiveness.
Frequently Updated Research: Ongoing research focuses on optimizing the adaptive loop filter algorithm for different types of multimedia content and exploring its applications in emerging technologies like virtual reality and augmented reality.
Questions about Adaptive Loop Filter Technology:
Question 1: How does the adaptive loop filter algorithm adapt to different types of multimedia content? Answer: The adaptive loop filter algorithm adjusts the filter set based on statistical information acquired for each picture, allowing it to optimize compression efficiency for various content types.
Question 2: What are the key differences between traditional loop filters and adaptive loop filters in terms of compression efficiency? Answer: Traditional loop filters apply a fixed filter set to all blocks, while adaptive loop filters dynamically allocate a single filter set based on statistical information, leading to improved compression efficiency.
Original Abstract Submitted
In order to achieve improved compression efficiency while controlling implementation costs, an adaptive loop filter includes an acquisition unit configured to acquire statistical information on a picture to be coded, an allocation unit configured to allocate a single filter set common to a plurality of blocks included in the picture, based on the statistical information on the picture, and a filter processing unit configured to execute adaptive loop filter processing on each of the plurality of blocks, by using the single filter set.
