Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If interface conversion is performed between different bandwidth interfaces, then compatibility between different consumer electronics products is improved, but viewing quality is degraded due to bandwidth limitations
Solution Approach 1:
The patent performs preliminary actions by comparing input data bandwidth with maximum output bandwidth before actual interface conversion, and proactively selects appropriate processing modes (original transmission, image compression, or color coding conversion) in advance to ensure optimal viewing quality while maintaining compatibility
Solution Approach 2:
The patent changes data transmission parameters dynamically by adjusting image compression ratios and color coding formats based on the bandwidth difference between input and output interfaces, thereby resolving the contradiction between compatibility and viewing quality
2Adaptability or versatility
If image compression is performed to reduce data bandwidth, then bandwidth compatibility is improved, but image quality is degraded
Solution Approach 1:
The patent applies partial compression only when necessary by first comparing bandwidth requirements and only performing image compression when the input bandwidth exceeds the maximum output bandwidth, rather than applying compression universally, thus maintaining image quality while ensuring compatibility
Solution Approach 2:
The patent dynamically adjusts the compression level and processing mode based on real-time bandwidth comparison results, selecting from multiple processing modes (original transmission, image compression, color coding conversion) to optimally balance compatibility and image quality
3Adaptability or versatility
If color coding conversion is performed to reduce data bandwidth, then bandwidth compatibility is improved, but color accuracy is degraded
Solution Approach 1:
The patent applies color coding conversion partially and selectively by first assessing the bandwidth difference and only performing color conversion when necessary, choosing from multiple color coding formats (RGB, YUV, YCbCr) to minimize color accuracy loss while achieving bandwidth compatibility
Data Source
AI summary
The present disclosure discloses a video interface conversion device that includes a first and a second interface transmission circuit, a color conversion circuit and an image compression circuit. The first and the second interface transmission circuit are respectively electrically coupled to an image source and a display terminal. The second interface transmission circuit negotiates a maximum output bandwidth with the display terminal such that the first interface transmission circuit compares an input data bandwidth of a data signal received from the image source and the maximum output bandwidth. When the maximum output bandwidth is smaller than the input data bandwidth, an image compression and/or a color coding conversion is performed on the data signal, and the data signal having the processed input data bandwidth being smaller than or equal to the maximum output bandwidth is further transmitted by the second interface transmission circuit to the display terminal.
