Innovation Solution
A video playback system that includes a location detection circuit and a multi-screen display controlling server, which dynamically detects the spatial location and orientation of each device, generates partitioned videos, and adjusts their display based on device positions, allowing flexible arrangement and combination of devices for joint video playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional video-wall systems are used with fixed screen arrangements, then video display capability is achieved, but flexibility and convenience are reduced
Solution Approach 1:
The patent implements dynamic screen arrangement by detecting the actual positions of portable devices and dynamically generating corresponding video partitioning schemes. The system transitions from fixed static arrangements to dynamic adaptive arrangements that automatically adjust to device positions, orientations, and screen specifications, thereby simultaneously achieving flexibility and ease of operation.
Solution Approach 2:
The system changes multiple parameters including screen coordinates, partitioning ratios, video resolution, and transmission formats based on detected device states. By dynamically adjusting these parameters according to actual device configurations, the system achieves both flexibility in device combination and convenience in user operation without requiring manual configuration.
2Area of stationary object
If multiple portable communication devices are used for joint display, then display area is increased, but device compatibility requirements increase
Solution Approach 1:
The patent enables universal compatibility across different portable communication devices by detecting their screen specifications, operating systems, and hardware capabilities, then automatically adapting the video partitioning and transmission format. This allows devices with different sizes, resolutions, and platforms to work together seamlessly, achieving both increased display area and broad device compatibility.
Solution Approach 2:
The system dynamically adjusts video parameters including resolution, bitrate, encoding format, and partitioning ratios based on each device's detected capabilities. This parameter adaptation enables devices with varying specifications to be integrated into the joint display system, simultaneously expanding total display area while maintaining compatibility across diverse device types.
3Device complexity
If fixed video signal formats are used, then system complexity is reduced, but arrangement flexibility is limited
Solution Approach 1:
The patent implements dynamic video signal generation that automatically adapts to detected device arrangements. Instead of requiring multiple fixed-format video files for different configurations, the system dynamically generates appropriate video signals based on real-time device positions and orientations, achieving arrangement flexibility without significantly increasing system complexity through automated detection and generation processes.
