==Method and System for Spatially Rendering Three-Dimensional (3D) Scenes - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240114313 titled 'Method and System for Spatially Rendering Three-Dimensional (3D) Scenes

==Simplified Explanation==

The method described in the abstract involves receiving an encoded audio signal for a 3D scene along with metadata indicating the positions of the sub-scene and sound source, rendering the scene spatially based on the listener's position, and adjusting the sound source position based on changes in the sub-scene position.

* Receiving a first bitstream with encoded audio signal and metadata
* Determining listener's position
* Spatially rendering the scene based on listener's position
* Receiving a second bitstream with different metadata
* Adjusting sound source position based on changes in sub-scene position

== Potential Applications ==
This technology could be applied in virtual reality (VR) and augmented reality (AR) environments to enhance the immersive experience by accurately positioning sound sources within the scene.

== Problems Solved ==
This technology solves the problem of maintaining spatial audio accuracy in dynamic 3D scenes where the positions of sound sources and sub-scenes may change.

== Benefits ==
The benefits of this technology include improved realism and immersion in VR and AR applications, as well as a more engaging audio experience for users.

== Potential Commercial Applications ==
Potential commercial applications of this technology include VR gaming, virtual tours, educational simulations, and interactive storytelling experiences.

== Possible Prior Art ==
One possible prior art for this technology could be spatial audio rendering techniques used in VR and AR applications, where sound sources are positioned dynamically based on the user's perspective.

=== Unanswered Questions ===

=== How does this technology impact the overall user experience in VR and AR applications? ===
This technology enhances the user experience by providing more realistic and immersive audio cues, but how does it specifically affect user engagement and enjoyment?

=== What are the technical requirements for implementing this spatial audio rendering method? ===
While the abstract outlines the general process, what specific hardware and software components are needed to effectively render spatial audio in dynamic 3D scenes?


==Original Abstract Submitted==

a method that includes receiving a first bitstream that includes an encoded version of an audio signal for a three-dimensional (3d) scene and a first set of metadata that has 1) a position of a 3d sub-scene within the scene and 2) a position of a sound source associated with the audio signal within the sub-scene; determining a position of a listener; spatially rendering the scene to produce the sound source with the audio signal at the position of the sound source with respect to the position of the listener; receiving a second bitstream that includes a second set of metadata that has a different position of the sub-scene; and adjusting the spatial rendering of the scene such that the position of the sound source changes to correspond to movement of the sub-scene from the position of the sub-scene to the different position of the sub-scene.
