Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cables are used to connect computing device and graphics display device, then stable data transmission is achieved, but user mobility is limited and safety hazards increase
Solution Approach 1:
The patent removes the cable connection from the system by implementing wireless communication between the computing device and graphics display device. The wireless interface extracts the data transmission function from the physical cable, eliminating mobility restrictions and safety hazards while maintaining connection functionality.
Solution Approach 2:
The patent replaces the mechanical cable connection with an electromagnetic wireless communication system. This substitution eliminates the physical constraints of cables while achieving the same data transmission purpose through electromagnetic waves.
2Manufacturing precision
If high-quality graphics transmission is implemented at high frame rates and resolutions, then visual quality is improved, but processing latency increases
Solution Approach 1:
The patent divides the graphics processing into separate functional segments: rendering is performed on the computing device while compression and transmission are handled by the wireless interface, and decompression is performed at the graphics display device. This segmentation allows parallel processing of different tasks, reducing overall latency while maintaining high visual quality.
Solution Approach 2:
The patent implements preliminary compression of graphics data at the source (computing device) before transmission. By pre-compressing the data, the system reduces the amount of data that needs to be transmitted wirelessly, thereby reducing transmission time and overall processing latency while maintaining high frame rates and resolutions.
3Ease of operation
If wireless communication is implemented between computing device and graphics display device, then user mobility is improved, but data transmission efficiency decreases
Solution Approach 1:
The patent employs advanced compression algorithms that dynamically adjust compression parameters based on the graphics content characteristics. This allows the system to achieve high compression ratios for complex scenes while maintaining low latency for simpler content, thereby improving overall data transmission efficiency in the wireless environment.
Solution Approach 2:
The wireless communication system dynamically adapts its transmission parameters including compression level, data rate, and resolution based on current mobility conditions and bandwidth availability. This dynamic adjustment optimizes data transmission efficiency while maintaining user mobility freedom.

AI summary
Embodiments of the subject matter described herein relate to a wireless programmable media processing system. In the media processing system, a processing unit in a computing device generates a frame to be displayed based on a graphics content for an application running on the computing device. The frame to be displayed is then divided into a plurality of block groups which are compressed. The plurality of compressed block groups are sent to a graphics display device over a wireless link. In this manner, both the generation and the compression of the frame to be displayed may be completed at the same processing unit in the computing device, which avoids data copying and simplifies processing operations. Thereby, the data processing speed and efficiency is improved significantly.
