Radio Receiver Visual Content Switching via Stored URLs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radio broadcasting receiving apparatuses are unable to quickly display visual content associated with broadcasting when switching between different broadcasting services, such as from DAB to FM, even if the content is the same, due to the lack of visual content URLs provided by the information service for the new service.
Innovation Solution
The apparatus includes a visual content display unit that acquires and displays visual content by switching to a different broadcasting service with the same content when the reception quality degrades, using a service that distributes visual content via the Internet and stores URLs for visual content from registered broadcasting services, ensuring continuous display of related visual content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the reception target broadcasting is switched to a different broadcasting service when reception quality degrades, then the broadcasting reception reliability is improved, but the visual content display continuity deteriorates because the new service may not have associated visual content URLs
Solution Approach 1:
The system performs preliminary actions by storing management information including visual content URLs of alternative broadcasting services in advance. When switching occurs, this pre-stored information enables immediate visual content display without interruption, resolving the contradiction between maintaining reception reliability and preserving visual content continuity.
2Reliability
If the reception target broadcasting is switched between different broadcasting services, then the broadcasting reception quality is improved, but the time required to acquire and display visual content increases
Solution Approach 1:
Management information including visual content URLs of alternative services is stored in advance before switching occurs. This preliminary preparation eliminates the time delay that would otherwise be required to acquire visual content URLs after switching, thus improving reception quality without sacrificing visual content display speed.
Solution Approach 2:
The system copies management information including visual content URLs from alternative broadcasting services and stores it locally. This copying mechanism allows the receiver to immediately access visual content information after switching without needing to query the information service again, reducing acquisition time while maintaining quality.
3Productivity
If the radio broadcasting receiving apparatus continuously acquires visual content URLs from the information service, then the visual content display availability is improved, but the energy consumption and communication overhead increase
Solution Approach 1:
The system extracts and stores essential management information including visual content URLs of alternative broadcasting services in advance, rather than continuously acquiring them. This extraction approach maintains visual content display availability while eliminating the need for continuous communication with the information service, thus reducing energy consumption and communication overhead.
Solution Approach 2:
Instead of continuous acquisition, the system performs information acquisition periodically or on-demand at specific moments (when switching occurs). This periodic action maintains display availability by having information ready when needed, while significantly reducing energy consumption compared to continuous acquisition.

AI summary
A URL of visual content of DAB currently being received, the visual content being acquired during reception of DAB and displayed, is stored. When reception target broadcasting is switched from the DAB to FM broadcasting that has a simultaneous broadcasting relationship with the DAB service, if a URL of visual content of the FM broadcasting currently being received is not acquired using RadioDNS, visual content is acquired from the stored URL of the visual content of the DAB that has the simultaneous broadcasting relationship with the FM broadcasting currently being received and is displayed.
