Electronic Apparatus Interface Switching via Display Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses connected to display devices cannot switch between multiple source apparatuses for image data supply without manual operation, limiting user control over interface switching.
Innovation Solution
An electronic apparatus with multiple interfaces and a control unit that switches operation modes in response to change requests from a display device, allowing the apparatus to transmit image data through different interfaces based on selected operation modes, enabling interface switching via the display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic apparatus is connected to multiple source apparatuses via multiple interfaces, then the versatility and adaptability of the system is improved, but the ease of operation deteriorates because the source apparatus cannot be switched by operating the display device
Solution Approach 1:
The patent introduces an intermediary control mechanism where the display device acts as a mediator to switch between different source apparatuses connected to the electronic apparatus. The display device sends a change request signal through the communication interface to the electronic apparatus, which then switches the operation mode to connect the desired source apparatus. This resolves the contradiction by enabling easy operation through the display device while maintaining multiple interface connections.
2Adaptability or versatility
If the electronic apparatus provides multiple input interfaces for different source apparatuses, then the adaptability is improved, but the device complexity increases due to multiple interfaces and switching mechanisms
Solution Approach 1:
The electronic apparatus is designed with multi-functionality to handle multiple source apparatuses through a single communication interface. The third interface serves dual purposes: transmitting image data from selected source apparatuses and receiving change requests for switching between sources. This universal design reduces device complexity by consolidating control and data transmission functions into a single interface while maintaining the capability to connect multiple sources.

AI summary
An electronic apparatus includes: first to third source-side IF units; and a control unit which causes one of the first to third source-side IF units to transmit image data inputted thereto, to a projector, when an operation mode of the electronic apparatus is a first operation mode, and which causes one of the first to third source-side IF units that is not the one of the first to third source-side IF units connected when in the first operation mode, to transmit image data inputted thereto, to the projector, when the operation mode of the electronic apparatus is a second operation mode. The control unit switches the operation mode to one of the first operation mode and the second operation mode in response to a change request received from the projector.
