Screen Casting Audio Switching for Consistent Mute State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen casting technologies face issues with audio status inconsistency between a PC device and a large-screen device, leading to a mismatch between the user's intended audio settings and the actual output during screen casting.
Innovation Solution
A screen casting method that dynamically adjusts audio status icons and volume settings based on user interactions, ensuring consistency by recording and applying initial audio settings, and managing audio output devices to align with user expectations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the PC device uses a screen casting application to cast audio/video content onto a large-screen device, then the screen casting function is implemented, but the audio status of the PC device may be inconsistent with the user's intended status before or during screen casting
Solution Approach 1:
The system records the initial audio status (mute or non-mute) of the PC device before screen casting begins. This preliminary recording ensures that when the sound output device is switched back to the PC device after screen casting, the audio status automatically returns to the user's original setting, resolving the inconsistency between intended and actual audio status
Solution Approach 2:
The system continuously monitors and detects changes in audio status during screen casting through an audio status detection module. When the sound output device is switched back to the PC device, the system provides feedback by automatically adjusting the audio status to match the recorded initial state, ensuring consistency with user expectations
2Ease of operation
If the sound output device is switched from the screen casting receive end to the screen casting transmit end, then audio output returns to the PC device, but the audio status may not match the user's expectations
Solution Approach 1:
Before screen casting begins, the system records the initial audio status of the PC device in an audio status table. When the sound output device is switched back to the PC device after screen casting, this recorded initial status is automatically applied, ensuring the audio status matches user expectations without requiring manual reconfiguration
Solution Approach 2:
The system dynamically adjusts the audio status of the PC device based on the current operational context. When screen casting is active, the audio status is managed according to the large-screen device's output status; when screen casting ends and audio output returns to the PC device, the system dynamically switches to the recorded initial audio status, making the transition seamless and user-friendly

AI summary
This application provides a screen casting method, a device, and a storage medium. The method is applied to a screen casting transmit end on which a screen casting application is installed. In a screen casting process, when a sound output device is switched to the screen casting transmit end, whether the screen casting transmit end outputs a sound depends on a current status of an audio status switching control, thereby ensuring that whether the screen casting transmit end outputs a sound can be consistent with an expectation of a user in a screen casting scenario. In addition, in the screen casting method provided in this application, when whether the screen casting transmit end outputs a sound is set based on a click operation performed by the user on the audio status switching control, an icon corresponding to the audio status switching control is dynamically modified based on an audio status (mute or non-mute) corresponding to the audio status switching control, to keep both auditory consistency and visual consistency with expectations of the user, thereby improving user experience.
