Display Audio Volume Handoff Between Monitor and Host
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices require users to manually adjust both the display device's output volume and the host device's system output volume, which can be inconvenient and inefficient.
Innovation Solution
A display device with a main control element that adjusts its own output volume and compares it with limits, generating a control command to adjust the host device's output volume via an interface control element when the limits are reached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the user manually adjusts both the display device's output volume and the host device's system output volume, then the volume control flexibility is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent merges the control functions of the display device and host device into a unified volume control system. The display device automatically sends control commands to the host device when volume limits are reached, combining what would otherwise be separate manual adjustment operations into a single automated process that maintains flexibility while improving ease of operation
Solution Approach 2:
The display device performs self-service by automatically detecting when its output volume reaches limits and autonomously generating control commands to adjust the host device's system output volume. This eliminates the need for user intervention to manually adjust both devices, thereby improving ease of operation while preserving volume control flexibility
2Ease of operation
If the display device automatically adjusts the host device's output volume when limits are reached, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent segments the volume control function into distinct modules: a main control element for adjusting output volume, an interface control element for generating control commands, and a comparison mechanism for detecting volume limits. This segmentation allows the automated functionality to be implemented through discrete, manageable components rather than a monolithic complex system
Solution Approach 2:
The interface control element acts as an intermediary between the main control element and the host device. It receives control commands from the main control element, processes them according to volume limit conditions, and transmits appropriate commands to the host device. This intermediary layer simplifies the overall system architecture by providing a clear interface layer that manages the complexity of inter-device communication

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 10 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.
