Keyboard Controller Video Playback Light Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices that play videos often have light signals that interfere with the user's visual experience, causing inconvenience during video playback.
Innovation Solution
An electronic system with a keyboard controller (KBC) that automatically turns off all light signals when a video is playing and turns them back on when the video is paused or stopped, using an embedded control random access memory (ECRAM) to store and manage the playing status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If light signals are kept on during video playback, then the electronic device provides normal operational feedback and status indication, but the light signals interfere with the user's visual experience when watching the video
Solution Approach 1:
The patent implements dynamic control of light signal states based on the video playback status. The keyboard controller automatically adjusts the light signals to be turned off during video playback and turned on when video playback stops, creating a dynamic adaptation to operational context that resolves the conflict between visual interference and operational feedback
Solution Approach 2:
The patent changes the operational parameter of light signals from a static on/off state to a dynamic state that responds to video playback conditions. By monitoring the playback status and adjusting the light signal parameter accordingly, the system eliminates visual interference during playback while maintaining operational feedback when needed
2Object-affected harmful factors
If the electronic device automatically controls light signals during video playback, then the user's visual experience is enhanced, but the system complexity increases due to additional control logic
Solution Approach 1:
The patent implements a self-service mechanism where the keyboard controller autonomously monitors video playback status and automatically adjusts light signal states without requiring user intervention. The system serves itself by detecting playback conditions and making appropriate control decisions, reducing the need for complex external control logic while achieving the desired effect
Solution Approach 2:
The patent establishes a feedback loop where the keyboard controller continuously monitors the video playback status and uses this information to control the light signal states. This feedback mechanism enables automatic adaptation to playback conditions, enhancing visual experience during playback while maintaining simplicity through rule-based control logic

AI summary
A method for playing videos, applied to an electronic system, is provided. A video is played through a player application program, and a playing status stored in an embedded control random access memory of a keyboard controller of the electronic system is set to a first status when the video is played. Then, all light signals of the electronic system are turned off by the keyboard controller according to the first status.
