Wireless Signal Quality Switching for Media Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems for transmitting media signals, such as video and audio, face inefficiencies due to variations in signal quality and distance, with high-frequency bands like WiHD offering fast transmission but short range and susceptibility to obstacles, while lower-frequency bands like WHDi provide longer range but slower speeds and potential image quality degradation.
Innovation Solution
A method and apparatus that convert media signals into different wireless communication standards (WiHD, WHDi, WiFi) based on detected signal quality and distance, allowing the system to automatically switch between standards to optimize transmission and reception performance, ensuring high-quality image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high-frequency band wireless communication (WiHD) is used for media signal transmission, then transmission speed is improved, but transmission range deteriorates and susceptibility to obstacles increases
Solution Approach 1:
The system dynamically changes the wireless communication standard parameter based on detected signal quality and distance. When signal quality is high and distance is short, it uses WiHD for fast transmission. When signal quality degrades or distance increases, it switches to WHDi or WiFi, sacrificing some speed for extended range and obstacle penetration.
Solution Approach 2:
The patent implements a dynamic switching mechanism that continuously monitors signal quality and automatically transitions between different wireless communication standards (WiHD, WHDi, WiFi) to optimize performance. This dynamic adaptation resolves the contradiction by allowing the system to operate at high speed when conditions permit and switch to longer-range modes when necessary.
2Speed
If high-frequency band wireless communication (WiHD) is used for media signal transmission, then transmission speed is improved, but reliability deteriorates due to obstacle susceptibility
Solution Approach 1:
The system changes the operational parameter (wireless standard) based on environmental conditions. When obstacles are detected or signal quality deteriorates, it switches from WiHD to WHDi or WiFi, which operate at lower frequencies with better penetration capabilities, thus maintaining reliability at the cost of some transmission speed.
Solution Approach 2:
The patent employs a feedback mechanism where the receiver detects signal quality and sends commands back to the transmitter to switch standards. This feedback loop ensures that when reliability deteriorates due to obstacles, the system automatically transitions to a more reliable communication mode.
3Ease of operation
If wireless communication is used for media signal transmission, then device portability is improved, but image quality deteriorates due to signal quality variations
Solution Approach 1:
The system dynamically adjusts the wireless communication parameter (standard selection) to maintain image quality. When signal quality is sufficient, it uses WiHD for portable operation. When signal quality deteriorates, it switches to WHDi or WiFi with error correction and retransmission mechanisms to preserve image quality, thus maintaining both portability and quality.
Solution Approach 2:
The patent implements error correction and retransmission mechanisms in advance to cushion against potential signal quality deterioration. When switching to lower-frequency bands, these protective measures ensure that image quality is maintained despite the reduced transmission speed.
