Digital Signage Device Diagnostic Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital signage devices lack the capability to display diagnostic data, making it difficult for technicians to perform routine testing and maintenance, as they rely on fixed content displays and do not provide operational or deployment information.
Innovation Solution
A signage device system that includes a display device capable of switching between media content display mode and diagnostic mode, equipped with a camera for capturing image frames, a processor, and non-volatile memory storing executable code to process images, detect demographic information, and switch modes upon diagnostic input, displaying both media content and diagnostic information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display device shows only media content in normal operation mode, then the display functionality is simple and reliable, but the device cannot provide diagnostic information for maintenance and troubleshooting
Solution Approach 1:
The display device implements dynamic mode switching between normal media content display and diagnostic information display. The controller receives input commands to transition between these modes, allowing the same hardware to adapt its functionality based on operational needs. This dynamic reconfiguration enables technicians to access diagnostic data without adding permanent dedicated display hardware for diagnostics.
Solution Approach 2:
The display device is designed to serve multiple functions: displaying media content during normal operation and displaying diagnostic information during maintenance. By integrating both functionalities into a single display system, the patent eliminates the need for separate diagnostic display hardware, reducing system complexity while maintaining reliability for both purposes.
2Loss of information
If the device collects and processes demographic data from captured images, then valuable operational insights are gained, but system complexity and processing requirements increase
Solution Approach 1:
The system performs preliminary action by capturing images with the integrated camera during normal operation before maintenance is needed. This pre-capture of demographic information allows the data to be processed and stored in advance, so that when maintenance occurs, the information is already available for review without requiring complex real-time processing during the maintenance window.
Solution Approach 2:
The controller acts as an intermediary between the camera/image processing functions and the display device. It manages the flow of demographic information from the image processing pipeline, stores it temporarily, and presents it in the diagnostic display mode. This intermediary role simplifies the overall system architecture by centralizing data management logic in the controller rather than requiring direct integration between all components.

AI summary
One aspect of the disclosure directs to a signage device, which include a display device, a camera, and a signage controller. The display device is configured to display media content in a display mode and display diagnostic information in a diagnostic mode. The diagnostic information includes content operational and deployment information related to the media content being displayed, and system information of the signage device. The signage controller is configured to control the camera to capture an image frame, process the captured image frame to generate information for a server system such that the server system provides the media content to the signage controller based on the generated information, display the media content on the display device in the display mode, switch the display device to the diagnostic mode in response to a diagnostic input command, and display the diagnostic information on the display device in the diagnostic mode.
