Display Wireless Band Switching for Streaming Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses experience deteriorated streaming service quality due to poor wireless communication quality, particularly in crowded frequency bands like 2.4 GHz, leading to buffering and reduced video resolution or frame rate.
Innovation Solution
A display apparatus with a wireless communication module capable of switching between 2.4 GHz and 5 GHz frequency bands, guided by a controller that searches for radio signals, identifies communication quality, and prompts users to switch to the 5 GHz band for improved performance when quality deteriorates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is performed in the 2.4 GHz band, then ease of operation and compatibility are improved, but communication quality deteriorates due to interference and crowding
Solution Approach 1:
The system changes the frequency band parameter from 2.4 GHz to 5 GHz to resolve communication quality issues. The controller monitors communication quality metrics and automatically switches frequency bands when deterioration is detected, maintaining reliable streaming while preserving ease of operation through automated parameter adjustment
2Reliability
If wireless communication quality is improved by switching frequency bands, then streaming service quality is improved, but device complexity increases
Solution Approach 1:
The display apparatus performs self-service by automatically monitoring its own wireless communication quality and autonomously switching frequency bands when deterioration is detected. The controller evaluates communication metrics and executes band switching without requiring external intervention or complex user configuration, thereby improving streaming reliability while minimizing the perceived complexity for users
3Reliability
If the 5 GHz band is used for wireless communication, then communication quality and bandwidth are improved, but coverage range and signal penetration deteriorate
Solution Approach 1:
The system dynamically adjusts the frequency band based on real-time communication quality monitoring. When quality deteriorates in the current band, the controller switches to an alternative band (2.4 GHz or 5 GHz) to maintain optimal performance. This dynamic adaptation allows the system to leverage the high bandwidth of 5 GHz when available while falling back to 2.4 GHz for better coverage, resolving the contradiction between communication quality and coverage range

AI summary
A display apparatus includes a display; a wireless communication module configured to wirelessly communicate in a first frequency band or a second frequency band; and a controller configured to control the wireless communication module to search for a radio signal transmitted from a wireless access point (WAP), to control the display to display identification information included in each of a plurality of radio signals received by the wireless communication module, and to display a message for guiding wireless communication with the WAP in the first frequency band on the display based on the user's selection of wireless communication with the WAP in the second frequency band. Accordingly, the display apparatus may guide the user's selection so as to perform wireless communication in a frequency band for optimal wireless communication based on the quality of wireless communication.
