Engineering Contradiction Analysis
1Productivity
If conventional video coding schemes are used to transmit and record videos, then the videos can be efficiently transmitted and recorded, but the image processing capabilities of the decoding apparatus are insufficient
Solution Approach 1:
The patent segments the decoding apparatus into distinct functional units: a decoding unit for decoding coded data, a segmentation metadata decoding unit for generating segmentation information, and an image processing unit for performing image processing. This segmentation allows each unit to specialize in specific tasks, improving overall image processing capability while maintaining manageable system complexity through modular design.
Solution Approach 2:
The image processing unit is designed to perform multiple image processing functions including super-resolution processing, segmentation-based processing, and other prescribed image processing operations. This multi-functionality enables the decoding apparatus to handle various image processing needs without requiring separate dedicated hardware for each function, thus improving productivity while controlling device complexity.
2Manufacturing precision
If super-resolution processing is added to enhance decoded image quality, then image quality improves, but the decoding apparatus requires additional processing units and metadata handling
Solution Approach 1:
The patent incorporates super-resolution metadata and segmentation metadata into the coded data during the encoding phase. This preliminary action prepares all necessary information in advance, allowing the decoding apparatus to perform super-resolution processing efficiently without requiring complex real-time analysis or additional hardware components beyond what is already integrated into the modular decoding structure.
3Manufacturing precision
If segmentation metadata and super-resolution metadata are incorporated into coded data, then image processing precision improves, but the data transmission and storage requirements increase
Solution Approach 1:
The patent extracts and separates metadata (segmentation metadata and super-resolution metadata) from the main video data, incorporating it as distinct elements within the coded data structure. This extraction allows the metadata to be handled independently, enabling efficient compression and selective processing. The metadata carries essential information for high-precision image processing without requiring the transmission of additional full-resolution image data, thus improving processing precision while controlling data quantity.
