Display Apparatus Substitutional Advertisement State Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses waste limited hardware resources when attempting to substitute advertisements without verifying their operational state, leading to failed advertisement playback.
Innovation Solution
The display apparatus verifies its operational state before executing the advertisement display application, ensuring the presence of operable hardware resources and unchanged broadcasting image conditions to prevent resource wastage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display apparatus executes an application for playing substitutional advertisement without verifying operational state, then the advertisement playback function is implemented, but hardware resources are wasted when the apparatus cannot support the advertisement display
Solution Approach 1:
The system performs preliminary verification of hardware resources and broadcasting image conditions before executing the advertisement playback application. The state verification unit checks whether the display apparatus has operable hardware resources and whether the broadcasting image meets substitution conditions, preventing resource wastage by avoiding execution when conditions are not met.
Solution Approach 2:
The system implements a feedback mechanism where the state verification unit continuously monitors the operational state of hardware resources and broadcasting image conditions. Based on this feedback, the control unit dynamically decides whether to execute or terminate the advertisement playback application, ensuring resources are not wasted on failed playback attempts.
2Loss of energy
If the display apparatus verifies operational state before executing advertisement application, then hardware resource wastage is prevented, but system complexity increases due to additional verification steps
Solution Approach 1:
The state verification unit combines multiple verification functions into a single integrated component: checking hardware resource availability, verifying broadcasting image substitution conditions, and determining application executability. This merging approach reduces system complexity compared to having separate verification modules for each condition.
Solution Approach 2:
The control unit is designed with multi-functionality, serving both as the primary controller for advertisement playback and as the decision-maker for whether to execute based on verification results. This universal design eliminates the need for a separate control module, reducing overall system complexity while maintaining verification functionality.
3Reliability
If the display apparatus checks hardware resources and broadcasting image state, then advertisement playback reliability is improved, but processing time increases due to verification steps
Solution Approach 1:
The system performs verification of hardware resources and broadcasting image conditions before initiating advertisement playback. By checking conditions in advance, the system avoids the time loss of attempting playback and then recovering from failures, making the overall process more efficient despite the initial verification time.
Solution Approach 2:
When verification determines that conditions are not met for advertisement playback, the system immediately skips the execution step and terminates the process. This prevents wasting time on unsuccessful playback attempts, making the verification process time-effective by quickly moving past unviable scenarios.

AI summary
A display apparatus includes a communication interface configured to receive a broadcasting image from a broadcasting transmission apparatus; a display configured to display the broadcasting image; a memory configured to store an application for displaying a substitutional advertisement image on the display instead of the broadcasting image; and a processor configured to: determine whether a state of the display apparatus satisfies a specified condition for displaying the substitutional advertisement image on the display; and if the state of the display apparatus satisfies the specified condition, execute the application to thereby cause the substitutional advertisement image to be displayed on the display instead of the broadcasting image.
