Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If video content is transmitted at high resolution and frame rate to improve video quality, then video quality is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts video transmission parameters (resolution, frame rate, color scale) based on real-time channel conditions and device power state. When power consumption is high, the system automatically reduces video quality parameters; when channel conditions improve or power state increases, it enhances video quality. This dynamic adaptation resolves the contradiction by making video quality variable rather than fixed.
Solution Approach 2:
The invention changes multiple video parameters simultaneously (horizontal and vertical resolution, frame rate, color scale) based on channel adaptive metrics. By adjusting these parameters according to power state and channel conditions, the system optimizes the balance between video quality and power consumption, directly addressing the technical contradiction.
2Manufacturing precision
If video content is transmitted with high detail and resolution, then video quality is improved, but data transmission requirements increase
Solution Approach 1:
The system dynamically adapts video transmission parameters to current channel conditions. When channel capacity is limited, it automatically reduces resolution and frame rate; when capacity increases, it enhances quality. This dynamic adjustment optimizes the balance between video quality and data transmission requirements.
Solution Approach 2:
The invention systematically adjusts multiple video parameters (horizontal resolution, vertical resolution, frame rate, color scale) based on channel adaptive metrics. This coordinated parameter changes approach ensures optimal video quality for available bandwidth, directly resolving the contradiction between quality and data quantity.
3Use of energy by moving object
If video transmission adapts to device parameters to improve efficiency, then power consumption is optimized, but device compatibility requirements increase
Solution Approach 1:
The system implements a universal adaptation mechanism that works across multiple device types and power states. By defining standardized power states (low, medium, high) and corresponding video parameter adjustments, the invention achieves broad device compatibility while optimizing power consumption for each device's capabilities.
Solution Approach 2:
The system dynamically adapts to different device power states and capabilities, automatically adjusting video transmission parameters to match each device's characteristics. This dynamic compatibility approach allows the same transmission system to efficiently serve diverse devices with varying power and display capabilities.

AI summary
A video transmission system includes a transceiver module that transmits a video signal to a remote device over at least one communications channel wherein the video signal is transmitted as at least one separate video layer stream chosen from, an independent video layer stream and at least one dependent video layer streams that require the independent video layer for decoding. A control module determines at least one channel characteristic of the at least one channel and chooses the at least one separate video layer stream based on the at least one channel characteristic of the at least one channel.
