US 2023/0065644 A1 · METHODS, APPARATUS AND SYSTEMS FOR 6DOF AUDIO RENDERING AND DATA REPRESENTATIONS AND BITSTREAM STRUCTURES FOR 6DOF AUDIO RENDERING

Abstract

The present disclosure relates to methods, apparatus and systems for encoding an audio signal into a bitstream, in particular at an encoder, comprising: encoding or including audio signal data associated with 3DoF audio rendering into one or more first bitstream parts of the bitstream, and encoding or including metadata associated with 6DoF audio rendering into one or more second bitstream parts of the bitstream. The present disclosure further relates to methods, apparatus and systems for decoding an audio signal and audio rendering based on the bitstream.

Claims14

Dependent claims

A method for decoding a bitstream comprising an encoded audio signal data associated with three degrees of freedom (3DoF) audio rendering and metadata associated with six degrees of freedom (6DoF) audio rendering, the method comprising:

receiving the bitstream,
decoding the encoded audio signal data associated with 3DoF to determine a decoded 3DoF audio signal;
and
rendering the decoded 3DoF audio signal based on at least one of 3DoF audio rendering and 6DoF audio rendering, wherein the rendering generates 6DoF audio signal data based on the decoded 3DoF audio signal and the metadata associated with 6DoF.
