Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional video coding techniques (HEVC, VVC) are used without temporal candidates for intra prediction, then the prediction process is simpler, but coding efficiency is suboptimal
Solution Approach 1:
The patent merges temporal candidates (from inter prediction) with spatial candidates (from intra prediction) to create a unified prediction mode selection process. The encoder considers both temporal and spatial prediction candidates together, selecting the best prediction mode that maximizes coding efficiency. This integration allows the system to leverage temporal information for intra prediction, improving coding efficiency while maintaining a unified and manageable prediction architecture.
2Productivity
If temporal candidates are incorporated into intra prediction, then coding efficiency improves, but the complexity of the prediction scheme increases
Solution Approach 1:
The patent implements a dynamic prediction mode selection mechanism where the encoder adaptsively chooses between temporal prediction, spatial prediction, or a combination thereof, based on the specific characteristics of each video block. The system dynamically adjusts the prediction approach rather than being fixed, allowing it to optimize coding efficiency for different scenarios while managing complexity through adaptive decision-making rather than rigid multi-mode handling.
