Adaptive Multi-Type Block Partitioning for Efficient Video Coding

The patent applies segmentation by dividing the block partitioning process into multiple hierarchical levels (quad-tree, binary-tree, and arbitrary partitioning stages). Each level handles specific partitioning scenarios, breaking down the complex encoding task into manageable segments that can be processed independently and systematically.

The patent implements dynamic block partitioning by allowing the encoder to adaptively select from multiple partitioning types (quad, binary, arbitrary) based on the characteristics of each block. This dynamic selection enables the system to optimize encoding efficiency for different content types while managing complexity through conditional logic rather than fixed structures.

The patent applies local quality by allowing different partitioning types to be applied to different blocks based on their specific characteristics. Each block can be independently analyzed and assigned the most appropriate partitioning method (quad, binary, or arbitrary), enabling localized optimization without requiring complex global coordination.

The patent implements preliminary action by establishing a hierarchical decision framework that evaluates blocks in a predetermined sequence (quad-tree first, then binary-tree, then arbitrary partitioning). This preliminary structuring of the decision process simplifies operation by providing a clear, step-by-step methodology for selecting partitioning types.
