Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content distribution systems face challenges in efficiently distributing high-quality content data between devices using different communication frequency bands, particularly when distance or obstacles interfere with wireless communication, leading to interruptions and reduced signal quality.
Innovation Solution
A content distribution device and method that dynamically switch between wireless communication channels in different frequency bands (2.4 GHz and 5 GHz) to maintain continuous data transmission, using the first frequency band for control and compressed content data when the second frequency band is unavailable, ensuring reliable and uninterrupted content distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If content data is transmitted using the second frequency band (5 GHz), then transmission speed and bandwidth are improved, but transmission reliability deteriorates when distance or obstacles are present
Solution Approach 1:
The system dynamically changes the frequency band parameter based on transmission conditions. When the second frequency band (5 GHz) provides sufficient signal quality, it is used for high-speed transmission. When signal quality deteriorates due to distance or obstacles, the system switches to the first frequency band (2.4 GHz) to maintain reliable transmission, thus adapting the frequency parameter to current conditions.
Solution Approach 2:
The patent implements dynamic frequency band selection rather than static assignment. The control unit continuously monitors transmission conditions and adjusts the frequency band used for content data transmission in real-time, allowing the system to transition between 2.4 GHz and 5 GHz bands based on current signal quality, distance, and obstacle conditions.
2Duration of action of stationary object
If the wireless communication channel is switched to maintain transmission, then transmission continuity is improved, but system complexity increases
Solution Approach 1:
The control unit performs preliminary assessment of transmission conditions before switching frequency bands. It monitors signal quality metrics and predicts potential transmission issues, allowing proactive switching to maintain continuity rather than reactive switching after interruption occurs.
Solution Approach 2:
The system implements feedback mechanisms where the control unit continuously monitors transmission quality and uses this information to determine when to switch frequency bands. The feedback loop ensures that switching decisions are based on actual transmission conditions, maintaining continuity while avoiding unnecessary switches that would increase complexity.
3Manufacturing precision
If high-frequency band (5 GHz) is used for content transmission, then data quality is improved, but signal stability deteriorates in the presence of obstacles
Solution Approach 1:
The system changes the frequency parameter based on obstacle detection and signal quality assessment. When obstacles are detected or signal stability deteriorates, the system switches from the 5 GHz band to the 2.4 GHz band, which has better penetration characteristics and longer wavelength, thus maintaining signal stability despite the lower data quality potential of the first band.
Data Source
AI summary
A content distribution device sends control data or content data to a first content receiving device over a wireless communication channel in a first frequency band. The device also sends the content data to a second content receiving device via a wired communication channel or via a wireless communication channel in a second frequency band that is different from the first frequency band. The device detects a performance reduction of the wired communication channel or the wireless communication channel in the second frequency band. In response to the detection, the device starts to send the content data to the second content receiving device via the wireless communication channel in the first frequency band while sending of the control data or the content data to the first content receiving device.
