Wireless Audio Extraction from Signage Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flat panel 'signage' displays typically lack audio components, and when audio is provided, noise from the environment often interferes with the audio output, making it difficult for viewers to fully experience multimedia content.
Innovation Solution
A system and method that uses a synchronization player application on electronic display devices to extract the audio component from multimedia content, packetize it, and broadcast it over a network for wireless computing devices to receive and play in synchronization with the visual component, ensuring that viewers can enjoy both audio and video components of the multimedia content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If audio is provided through speakers of flat panel signage displays, then audio output is available, but environmental noise interferes with the audio quality
Solution Approach 1:
The patent extracts the audio component from the multimedia content on the electronic display device and transmits it separately to wireless computing devices. This separates the audio delivery path from the environmental noise source, allowing users to receive clear audio through their personal devices rather than through the display's speakers which are subject to environmental interference.
Solution Approach 2:
The patent introduces a network as an intermediary between the electronic display device and the wireless computing device. The audio data is transmitted through this intermediary channel, bypassing the physical constraint of speakers in noisy environments and delivering audio quality through a controlled digital transmission path.
2Reliability
If audio is transmitted to wireless computing devices, then audio quality is improved, but system complexity increases
Solution Approach 1:
The patent utilizes existing multi-functional components: the electronic display device's processor serves both visual display and audio extraction functions, the network interface handles both data communication and audio streaming, and wireless computing devices receive both visual and audio content through standard communication protocols. This avoids adding dedicated specialized components.
Solution Approach 2:
The patent leverages the inherent capabilities of existing devices without requiring additional specialized hardware. The electronic display device self-provides audio extraction and transmission functions using its existing processing and networking capabilities, and wireless computing devices self-receive and play audio using their standard audio playback functionality.

AI summary
A system and method for providing an audio component of a multimedia content playing on an electronic display device to one or more wireless computing devices utilizes a synchronization player application of the electronic display device to display a visual component of the multimedia content on a display of the electronic display device and to extract the audio component from the multimedia content. The extracted audio component of the multimedia content is packetized into data packets and broadcast into a network so that the data packets can be received by the wireless computing devices to play the audio component of the multimedia content in synchronization with the visual component of the multimedia content being displayed on the display of the electronic display device.
