Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image quality improvement technology information is stored in VVC bitstream, then image quality can be improved, but client processing complexity increases due to extraction and parsing requirements
Solution Approach 1:
The patent extracts the image quality improvement technology information from the complex VVC bitstream structure and places it in a separate, easily accessible location within the content file. This allows clients to access the information without parsing the entire bitstream, reducing processing complexity while maintaining image quality improvement capabilities
Solution Approach 2:
The patent introduces an intermediary structure (separate information storage location) between the encoded image data and the client processing. This intermediary contains the image quality improvement technology information in a format that is easy to access and interpret, acting as a bridge that simplifies client access while preserving the technical details needed for image quality enhancement
2Ease of operation
If image quality improvement technology information is stored in content file, then client access is simplified, but data transmission volume increases
Solution Approach 1:
The patent applies local quality by storing only the necessary image quality improvement technology information in the content file, rather than duplicating entire bitstreams. The information is placed locally where it can be efficiently accessed by clients without requiring transmission of redundant data, balancing accessibility with transmission efficiency
3Manufacturing precision
If comprehensive image quality improvement technology information is provided, then image quality can be maximized, but client device requirements become more stringent
Solution Approach 1:
The patent implements partial action by providing image quality improvement technology information that can be selectively applied. Clients can choose to use only the portions of the information that their devices are capable of processing, while more powerful devices can utilize the complete set of information. This allows comprehensive information to be provided without mandating high device requirements, as clients can selectively apply what they need
