Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fixed coding order is used for video sub-blocks, then the device complexity is reduced, but the video compression efficiency deteriorates
Solution Approach 1:
The patent implements a dynamic coding order determination mechanism that adapts to different video content characteristics. The system analyzes reference blocks and determines optimal coding orders based on gradient calculations and content properties, transitioning from static fixed orders to adaptive dynamic orders that improve compression efficiency while managing complexity through algorithmic optimization
Solution Approach 2:
The patent changes the coding order parameters based on video content analysis. By calculating gradients between reference blocks and adjusting coding sequences according to content characteristics (such as smoothness, edges, or textures), the system optimizes compression efficiency by prioritizing coding of sub-blocks that contribute most to reconstruction quality
2Manufacturing precision
If the number of video sub-blocks is increased, then the manufacturing precision of video reconstruction is improved, but the loss of time increases
Solution Approach 1:
The patent divides video blocks into multiple sub-blocks to enable finer-grained prediction and reconstruction. By segmenting the video block into smaller units, the system achieves higher reconstruction precision through localized adaptation to content characteristics, while the segmented structure allows for parallel processing optimization
Solution Approach 2:
The patent performs preliminary gradient calculations and reference block analyses before determining the final coding order. By pre-computing content-based metrics and establishing priority sequences in advance, the system reduces real-time processing time while maintaining high reconstruction precision through pre-optimized coding sequences
3Loss of substance
If adaptive coding order determination is implemented, then the bit rate is reduced, but the device complexity increases
Solution Approach 1:
The patent dynamically changes coding parameters including coding order, prediction mode selection, and transformation types based on analyzed video content characteristics. This adaptive parameter adjustment reduces bit rate by optimizing the representation of different content types (smooth areas, edges, textures) while managing complexity through efficient algorithm design
Solution Approach 2:
The patent replaces complex mechanical or hardware-based optimization systems with software-based gradient calculations and content analysis algorithms. By using computational methods to determine optimal coding orders, the system achieves bit rate reduction through intelligent decision-making while avoiding the complexity of dedicated hardware circuits for each optimization function
