Display Audio Volume Handoff at Host Control Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices do not allow users to conveniently adjust the system output volume value of the host device when adjusting the output volume value of the display device itself.
Innovation Solution
A display device with a main control element to adjust its own output volume value and compare it with limits, generating a control command to adjust the host device's output volume value through a dedicated interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display device only adjusts its own output volume value, then the control mechanism remains simple, but the user cannot conveniently adjust the system output volume value of the host device
Solution Approach 1:
The patent combines the display device's volume control with the host device's system volume control into a unified control mechanism. When the display device's volume reaches its limit (upper or lower bound), the system automatically generates control commands to adjust the host device's system output volume, allowing users to control both volumes through a single interface without increasing operational complexity
Solution Approach 2:
The patent introduces an interface control element that acts as an intermediary between the display device and the host device. This element detects when the display device's volume reaches its limits and automatically generates appropriate control commands to adjust the host device's system volume, enabling seamless volume control without requiring users to manually adjust both devices
2Ease of operation
If the display device adjusts both its own output volume and the host device's system output volume, then the user convenience is improved, but the control mechanism complexity increases
Solution Approach 1:
The system implements self-service by automatically detecting when the display device's volume reaches its upper or lower limit and autonomously generating control commands to adjust the host device's system volume. This automation eliminates the need for complex manual intervention while maintaining simple user interaction, as the system handles the coordination between both volume controls automatically

AI summary
A display device capable of providing a first audio, which is coupled to a host device through a first interface, performs the following operations. A first output volume value of the display device is adjusted according to a first control command, and the first output volume value is compared with an upper limit value or a lower limit value to generate a first comparison result. The first audio is generated according to the first output volume value and a second output volume value of the host device. When the first control command indicates increasing or decreasing the first output volume value, and the first comparison result indicates that the first output volume value is equal to the upper limit value or the lower limit value, a second control command is sent to the host device through the first interface to adjust the second output volume value.
