Live Venue Audio Distribution with Spatial Sound Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing live data distribution systems fail to provide a realistic sensation of a live venue to the distribution destination, as they only display icon information without immersive audio and spatial localization.
Innovation Solution
A live data distribution system that obtains sound source information and position information from a first venue, performs localization processing, and distributes this data to a second venue, incorporating sound localization and spatial reverberation to create an immersive audio-visual experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If icon information is displayed to show user reactions, then information about user reactions is transmitted, but realistic sensation of the live venue is not provided
Solution Approach 1:
The patent creates a virtual copy of the live venue environment by capturing spatial audio data, microphone positions, and acoustic characteristics at the first venue, then reproducing this virtual environment at the second venue. This virtual copy preserves the realistic sensation of the live venue while transmitting user reaction information through the reproduced audio field, resolving the contradiction between information transmission and realistic sensation.
Solution Approach 2:
The patent introduces a virtual venue as an intermediary between the physical first venue and the second venue. This virtual venue acts as a mediator that captures the acoustic environment and user reactions from the first venue and reproduces them at the second venue, enabling both information transmission and realistic sensation without direct physical connection.
2Reliability
If sound source information and position information are obtained and localization processing is performed, then realistic spatial audio is provided, but system complexity increases
Solution Approach 1:
The patent performs preliminary actions by pre-capturing and storing the acoustic environment data, microphone positions, and spatial characteristics of the first venue before distribution. This preliminary preparation of the virtual venue environment enables efficient real-time reproduction at the second venue without requiring complex real-time processing, thus reducing system complexity while maintaining realistic sensation.
Solution Approach 2:
The patent segments the audio transmission into distinct components: spatial audio data from specific microphone positions, ambient sound fields, and localized sound sources. Each component is processed and reproduced separately, allowing the system to manage complexity by handling individual audio elements independently rather than processing the entire audio environment as a single complex signal.
Data Source
AI summary
A live data distribution method obtains first sound source information according to sound of a first sound source generated at a first location of the first venue and position information of the first sound source, and second sound source information according to a second sound source including an ambient sound generated at a second location of the first venue, as distribution data, distributes the distributed data to the second venue, and renders the distribution data and providing first sound of the first sound source having been performed with localization processing based on the position information of the first sound source, and second sound of the second sound source, at the second venue.
