==METHOD AND APPARATUS FOR ENCODING THREE-DIMENSIONAL AUDIO SIGNAL, ENCODER, AND SYSTEM - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240119950 titled 'METHOD AND APPARATUS FOR ENCODING THREE-DIMENSIONAL AUDIO SIGNAL, ENCODER, AND SYSTEM

==Simplified Explanation==

The abstract describes a method for encoding a three-dimensional audio signal, where an encoder determines coding efficiency of a virtual speaker and selects an updated virtual speaker based on preset conditions.

* Encoder obtains current frame of three-dimensional audio signal
* Encoder determines coding efficiency of initial virtual speaker for current frame
* If coding efficiency meets preset condition, encoder selects updated virtual speaker from candidate set
* Encoder encodes current frame based on updated virtual speaker to obtain first bitstream
* If coding efficiency does not meet preset condition, encoder encodes current frame based on initial virtual speaker to obtain second bitstream

== Potential Applications ==

==Original Abstract Submitted==

a method for encoding a three-dimensional audio signal is provided. the method includes: an encoder obtains a current frame of a three-dimensional audio signal; obtains coding efficiency of an initial virtual speaker for the current frame based on the current frame of the three-dimensional audio signal; and when the coding efficiency of the initial virtual speaker for the current frame meets a preset condition, determines an updated virtual speaker for the current frame from a set of candidate virtual speakers; encodes the current frame based on the updated virtual speaker for the current frame, to obtain a first bitstream; or when the coding efficiency of the initial virtual speaker for the current frame does not meet the preset condition, encodes the current frame based on the initial virtual speaker for the current frame, to obtain a second bitstream.
