Wireless Mirror Transmission Audio Path Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mirror transmission technologies experience unstable data transmission and audio signal disruptions due to insufficient bandwidth or network surges, leading to non-continuous audio and shock-wave noises when using portable electronic devices to stream multimedia to larger displays.
Innovation Solution
A method that continuously monitors network stability and adjusts the retrieval and transmission of audio and image data, stopping audio transmission to the receiver when unstable and controlling audio playback on the transmitter device, while adjusting image frame parameters to reduce data transmission and prevent disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio signals are transmitted wirelessly from transmitter to receiver electronic device, then mirror transmission function is achieved, but audio signal becomes non-continuous and produces shock-wave noises when network bandwidth is insufficient
Solution Approach 1:
The patent extracts the audio signal transmission path from the wireless network transmission path. When network instability is detected, the audio signal is routed directly from the transmitter's audio module to the receiver without passing through the unstable wireless network channel, thereby eliminating shock-wave noises and ensuring continuous audio playback
Solution Approach 2:
The patent introduces a network status monitoring mechanism as an intermediary that detects network stability and dynamically switches the audio signal transmission path. This mediator ensures that audio signals bypass the unstable network channel when necessary, preventing audio disruptions while maintaining mirror transmission functionality
2Reliability
If image frames are transmitted continuously over wireless network, then mirror display is achieved, but data transmission becomes unstable when bandwidth is insufficient
Solution Approach 1:
The patent applies partial action by selectively transmitting only essential data over the wireless network while handling audio signals through a direct connection. This reduces the overall data transmission amount over the network, preventing bandwidth exhaustion and transmission instability while maintaining complete mirror transmission functionality
Solution Approach 2:
The patent segments the transmission data into two categories: image frames transmitted over the wireless network and audio signals transmitted through a direct connection. This segmentation allows optimized transmission paths for each data type, improving overall transmission stability and reducing network burden
Data Source
AI summary
A mirroring transmission method is provided. The present method retrieves image frames and audio signals of a transmitter and transmits the retrieved image frames and retrieved audio signals to a receiver to be displayed wirelessly. In the meantime, the present method monitors status of a network connected with the transmitter and the receiver, and determines if the network is stable or not. Also, the method stops retrieving and transmitting the audio signal from the transmitter to the receiver, and controls the transmitter to display the audio signal directly through an internal audio module whenever the network is determined unstable.
