Real-Time Live Event A-V Synchronization With Separate Professional Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld audio-visual recording devices often capture low fidelity audio signals during live events, which fail to adequately represent the sound quality of performances due to inherent limitations in integrated microphones and background noise, detracting from the appreciation of artistic or oratory performances.
Innovation Solution
A system and method for real-time synchronization of high quality audio segments generated by sound board equipment with video segments recorded by audience members, using A-V Synchronization Application on reception devices, allowing for the creation of high fidelity audio-visual files.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If integrated microphones in handheld AV recording devices are used to capture audio during live events, then the recording device can capture both video and audio simultaneously, but the audio quality is low fidelity and lacks sufficient sound quality to clearly capture the performance
Solution Approach 1:
The patent introduces an audio replacement service as an intermediary system that receives low fidelity audio from handheld recording devices and substitutes it with high fidelity audio from professional sound board equipment. This mediator enables the combination of versatile handheld video capture with professional-grade audio quality without requiring the handheld device itself to have superior audio capabilities.
Solution Approach 2:
The system creates a copy of the audio portion from professional sound board recordings and replaces the original low fidelity audio captured by the handheld device. This copying approach allows the video from the handheld device to be paired with high quality audio from a separate professional recording source.
2Measurement precision
If professional sound board equipment is used to capture high fidelity audio during live events, then the audio quality is significantly improved, but the audio cannot be directly integrated with video segments recorded by audience members using handheld devices
Solution Approach 1:
The audio replacement service creates a universal system that can work with multiple sources of video footage from different handheld devices while consistently providing high fidelity audio replacement. This multi-functional platform enables professional audio to be integrated with various consumer-grade video recordings through a common interface and process.
Solution Approach 2:
The patent introduces an audio replacement service as an intermediary system that receives low fidelity audio from handheld recording devices and substitutes it with high fidelity audio from professional sound board equipment. This mediator enables the combination of versatile handheld video capture with professional-grade audio quality without requiring the handheld device itself to have superior audio capabilities.
3Ease of operation
If low fidelity audio signals are used in AV recordings of live events, then the recording process is simple and devices are portable, but the sound quality detracts from appreciation of artistic or oratory performances
Solution Approach 1:
The system enables handheld recording devices to automatically participate in high fidelity audio replacement by simply uploading their video and audio files to the audio replacement service. The device serves itself by capturing video with its built-in microphone and then allowing the service to replace the audio portion, eliminating the need for the device to have complex audio processing capabilities while still achieving high sound quality.

AI summary
Systems and methods are presented herein that facilitate temporally synchronizing a separately-sourced high-quality audio segment of a live event with a video segment that is generated by a recording device associated with a member of the audience. An A-V Synchronization Application may synchronize a video segment of a live event that is generated from a personal electronic device of an audience member with a high quality audio segment that is separately sourced and generated by professional sound recording equipment at the live event. The result of the temporal synchronization is a high fidelity digital audio visual recording of the live event. An audience member may stream, in real-time, the high fidelity digital audio visual recording to an additional electronic device at a different geo-location. In some examples, narrative audio segments may be also included as part of the high fidelity digital audio visual recording.
