Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple encoding blocks are encoded separately using existing video compression schemes, then each block can be independently processed, but the bit usage increases and encoding performance decreases

Engineering Contradiction:
Improveencoding efficiencyVSAvoidbit usage
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent combines multiple encoding blocks of maximum size into a single encoding unit group, treating them as one unified encoding entity. This merging approach allows shared encoding information to be applied across all blocks in the group, reducing redundant bit usage while maintaining independent processing capabilities where needed.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If various block partitioning structures with different block depths and sizes are used, then encoding flexibility improves, but the number of bits required to express block structures and represent block data increases significantly

Engineering Contradiction:
Improveblock partitioning flexibilityVSAvoidbits for block structure representation
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent segments the video content into encoding units of maximum size that are then grouped together. This segmentation approach maintains flexibility by allowing different partitioning structures within groups while reducing the overhead for representing block structures, as the grouping hierarchy provides a compact way to describe the overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The encoding unit group serves as a universal container that can accommodate multiple blocks with different partitioning structures. By creating this multi-functional grouping mechanism, the system can handle various block depths and sizes while using a standardized approach to represent the collective structure, reducing the total bits required.

Inventive Principle:
Principle #6Universality (Multi-functionality)
