HIGHER ORDER AMBISONICS ENCODING AND DECODING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18246030 titled 'HIGHER ORDER AMBISONICS ENCODING AND DECODING

Simplified Explanation

The patent application is about encoding and decoding higher order ambisonics (HOA) data to reduce bitrate. It involves using principal components analysis to generate spatial descriptors and employing different techniques to quantize these descriptors.

• The patent application focuses on encoding and decoding higher order ambisonics (HOA) data.
• The purpose of this technology is to reduce the bitrate required for transmitting HOA data.
• Principal components analysis is used to create spatial descriptors, which capture the spatial characteristics of the audio.
• These spatial descriptors are then quantized using various techniques.
• The innovation lies in the combination of principal components analysis and spatial descriptor quantization to achieve bitrate reduction for HOA data.

Original Abstract Submitted

Encoding and decoding of higher order ambisonics, HOA, data for purposes of bitrate reduction. One aspect uses principal components analysis to produce spatial descriptors. Other aspects include various spatial descriptor quantization techniques.
