Video Unit Partitioning Rules for Higher Coding Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video coding standards face challenges in efficiently managing partitioning schemes for video data, leading to suboptimal bandwidth usage and compression efficiency, particularly as the demand for digital video increases with the rise in connected devices.
Innovation Solution
A method is introduced to determine and apply a second partitioning scheme for video units based on rules related to parent and ancestor video units, including ternary partitioning schemes, to optimize coding and reduce bandwidth demands.

1Productivity
If multiple partitioning schemes are used for video coding, then compression efficiency is improved, but device complexity increases
Solution Approach 1:
The video coding process is segmented into multiple partitioning schemes (first and second partitioning schemes) that can be selectively applied to different video units. This allows the system to divide complex video data into manageable segments using appropriate partitioning methods, improving compression efficiency without requiring all schemes to be applied uniformly throughout the entire video stream.
Solution Approach 2:
The patent implements dynamic selection of partitioning schemes based on video content characteristics and coding conditions. The encoder can adaptively choose between the first partitioning scheme and the second partitioning scheme (such as ternary partitioning) for different video units, allowing the system to respond to varying content requirements rather than using a static partitioning approach.
2Loss of energy
If advanced partitioning schemes are applied, then bandwidth utilization is improved, but coding complexity increases
Solution Approach 1:
Different partitioning schemes are applied to different video units based on their local characteristics. The second partitioning scheme (e.g., ternary partitioning) is selectively enabled for specific video units where it provides benefits, rather than applying it uniformly to all video content. This localized application optimizes bandwidth utilization for regions that benefit most while avoiding unnecessary complexity elsewhere.
Solution Approach 2:
The patent changes the partitioning parameter (scheme selection) based on video content analysis and coding conditions. By dynamically adjusting which partitioning scheme is applied to different video units, the system optimizes bandwidth utilization without requiring the maximum complexity for all coding operations.
