Audio Device Extracting Multimedia Stream Audio for Wireless Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for delivering audio with video on wireless devices are hindered by environmental noise, individual preferences, and the inability to synchronize audio across multiple viewers, often requiring buffering that disrupts video signal delivery.
Innovation Solution
An audio device extracts and packetizes the audio component of a multimedia stream, transmitting it via a network to wireless computing devices in synchronization with the visual component, without affecting the visual output, using a processor, memory, and synchronization player application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio is transmitted to wireless devices to allow individual listening preferences, then audio quality and personalization are improved, but synchronization delay and buffering issues occur
Solution Approach 1:
The system separates audio processing from video processing by having the audio device extract only the audio component from the multimedia stream, while the video monitor displays only the visual component. This segmentation allows independent processing paths without mutual interference, enabling real-time audio transmission without video buffering delays.
Solution Approach 2:
The audio device extracts the audio component from the multimedia stream received from the video provider, isolating it from the video signal. This extraction enables the audio to be processed and transmitted separately to wireless devices without being constrained by video buffering requirements, thus eliminating synchronization delay.
2Area of stationary object
If loudspeakers are used to broadcast audio for multiple viewers, then audio coverage is improved, but environmental noise interference and lack of individual control increase
Solution Approach 1:
The system transitions from spatial audio distribution (loudspeakers broadcasting to multiple viewers in the same physical space) to network-based audio distribution (transmitting audio packets over a network to individual wireless devices). This dimensional shift allows each viewer to receive audio privately in their own acoustic environment, eliminating environmental noise interference while maintaining individual listening preferences.
3Reliability
If video buffering is implemented to accommodate audio multicasting, then audio transmission reliability is improved, but video signal delivery delay increases
Solution Approach 1:
The system divides the multimedia stream into separate audio and video components that are processed independently. The audio device extracts and transmits only the audio component as packets over the network, while the video monitor displays the visual component without buffering. This segmentation eliminates the need for video buffering to accommodate audio multicasting, maintaining both audio transmission reliability and video signal delivery speed.
Data Source
AI summary
A device, system, and method may provide an audio component of a multimedia stream playing on a video monitor to one or more wireless computing devices. The extracted audio component of the multimedia content may be packetized into data packets and broadcast via a network such that the data packets can be received by the wireless computing devices and the audio component can be played by the wireless computing devices in synchronization with the visual component playing on the video monitor.
