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 18538708 titled 'METHOD AND APPARATUS FOR ENCODING THREE-DIMENSIONAL AUDIO SIGNAL, ENCODER, AND SYSTEM
Simplified Explanation
The method described in the patent application involves encoding a three-dimensional audio signal using virtual speakers. Here are some key points to explain the innovation:
- Encoder processes current frame of three-dimensional audio signal
- Determines coding efficiency of initial virtual speaker for current frame
- If coding efficiency meets preset condition, selects updated virtual speaker from candidate set
- Encodes current frame based on updated virtual speaker to obtain first bitstream
- If coding efficiency does not meet preset condition, encodes current frame based on initial virtual speaker to obtain second bitstream

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.
