Video Unit Partitioning Rules for Higher Compression Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video coding standards face challenges in efficiently managing video partitioning schemes, leading to suboptimal bandwidth usage and compression efficiency, particularly as the demand for digital video increases with the rise in connected devices.
Innovation Solution
Implementing a method for determining and applying a second partitioning scheme for video units based on rules related to parent and ancestor units, including constraints on partitioning types such as unsymmetrical quadtree, binary tree, and ternary tree schemes, to optimize coding and decoding processes.

1Productivity
If multiple partitioning schemes are used for video coding, then compression efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic partitioning scheme selection where the coding apparatus adaptively chooses between first and second partitioning schemes based on video content characteristics and coding conditions. This dynamic approach allows the system to optimize compression efficiency for different video scenarios while managing complexity through conditional logic rather than permanently implementing all possible partitioning schemes.
Solution Approach 2:
The patent changes the parameter of partitioning scheme type based on coding conditions, switching between different partitioning approaches (e.g., quadtree, ternary tree, binary tree) depending on the specific video block being coded. This parameter change strategy enables the system to achieve high compression efficiency when needed while maintaining lower complexity for standard cases.
2Loss of energy
If video partitioning is optimized for compression, then bandwidth requirements are reduced, but coding complexity increases
Solution Approach 1:
The patent segments the video coding process into distinct phases where different partitioning schemes are applied to different video blocks. By dividing the overall coding task into segments that can use optimized partitioning strategies, the system reduces the total bandwidth required while distributing the coding complexity across manageable segments rather than applying complex schemes uniformly throughout.
Solution Approach 2:
The patent applies advanced partitioning schemes selectively to only those video blocks that benefit from them, rather than applying complex partitioning to all blocks. This partial action approach reduces bandwidth requirements for challenging video content while maintaining lower coding complexity for standard blocks that don't require sophisticated partitioning.
