Direction-Dependent 3D Audio for Multi-Entity Telecommunication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications technologies, such as voice chat and videotelephony, lack the authenticity of face-to-face communication and can be challenging for users to accurately determine the geographic location of others due to insufficient spatial information in audio messages, leading to misunderstandings and difficulties in geolocation.
Innovation Solution
A remote device receives multi-stream content, including audio streams, and orientation information from audio-producing entities to provide direction-dependent, three-dimensional audio, enabling a multi-stereo audio output device to reproduce spatial audio as if the audio is originating from a specific direction, elevation, or proximity, corresponding to the physical location of the entities.

Engineering Contradiction Analysis
1Ease of operation
If traditional voice chat or videotelephony is used, then communication convenience is improved, but spatial location accuracy and communication authenticity deteriorate
Solution Approach 1:
The patent transitions from traditional two-dimensional audio representation (left/right channels) to three-dimensional spatial audio by incorporating elevation and distance dimensions. This is achieved through multi-stream content delivery that includes orientation information and spatial position data, enabling the audio system to reproduce sound sources in three-dimensional space rather than just horizontal planes.
Solution Approach 2:
The patent introduces an intermediary processing system that receives multi-stream content from audio-producing entities, processes orientation and spatial information, and delivers enhanced audio signals to the audio output device. This intermediary layer transforms raw audio data into spatially-encoded signals that convey location information without requiring direct peer-to-peer device communication.
2Measurement precision
If multi-stream content with orientation information is processed, then spatial audio accuracy is improved, but device complexity increases
Solution Approach 1:
The patent segments the audio processing system into distinct functional components: audio-producing entities that capture spatial data, communication networks that transmit multi-stream content, remote devices that process orientation information, and audio output devices that reproduce spatial audio. This segmentation allows each component to handle specific tasks independently, reducing overall system complexity despite the enhanced capabilities.
Solution Approach 2:
The patent creates a universal multi-stream content delivery framework that can handle various types of spatial audio scenarios (one-on-one calls, group calls, conference calls) using the same technical approach. The system processes different audio entities and spatial configurations through a unified architecture, reducing the need for separate specialized systems for each communication scenario.

AI summary
The document describes systems and techniques directed at three-dimensional, direction-dependent audio for multi-entity telecommunication. In aspects, a remote device receives multi-stream content, including at least one audio stream, from one or more audio-producing entities and obtains orientation information associated with the one or more audio-producing entities. The remote device can then, using the at least one audio stream and the orientation information, provide direction-dependent, three-dimensional audio sufficient to enable a multi-stereo audio output device to reproduce the spatial audio as if the at least one audio stream is originating from a direction, an elevation, and/or a proximity that corresponds to a physical location of the one or more audio-producing entities.
