Engineering Contradiction Analysis
1Measurement precision
If pixel values of three-dimensional video data are transmitted directly, then transmission precision is maintained, but bandwidth consumption increases and transmission delay increases
Solution Approach 1:
The patent extracts only the essential information from pixel values by determining a coding-mapping relationship that maps pixel values to code values. Instead of transmitting all pixel value data, only the code values representing the essential visual information are transmitted, reducing data volume while preserving transmission precision.
Solution Approach 2:
The patent changes the parameter representation from direct pixel values to coded values through a dynamically determined coding-mapping relationship. This parameter transformation reduces the data volume required for transmission while maintaining the essential visual information quality.
2Measurement precision
If pixel values of three-dimensional video data are transmitted directly, then transmission precision is maintained, but bandwidth consumption increases
Solution Approach 1:
The patent extracts only the essential information from pixel values by determining a coding-mapping relationship that maps pixel values to code values. Instead of transmitting all pixel value data, only the code values representing the essential visual information are transmitted, reducing bandwidth consumption while preserving transmission precision.
3Loss of information
If pixel values of three-dimensional video data are transmitted directly, then data completeness is maintained, but transmission delay increases
Solution Approach 1:
The patent extracts only the essential information from pixel values by determining a coding-mapping relationship that maps pixel values to code values. Instead of transmitting all pixel value data, only the code values representing the essential visual information are transmitted, reducing transmission delay while maintaining data completeness.
4Device complexity
If a fixed coding-mapping relationship is used, then device complexity is reduced, but adaptability to different precision and delay requirements decreases
Solution Approach 1:
The patent implements a dynamic coding-mapping relationship that can be adjusted based on different precision and delay requirements. The terminal device determines the appropriate coding-mapping relationship according to the specific service requirements, enabling the system to adapt to varying conditions while maintaining manageable complexity through standardized coding mechanisms.
