A method and apparatus for transmitting and receiving 3D audio data, including generating and encoding reproduction information with transition effects, allowing users to seamlessly transition between audio scenes in VR or AR content, utilizing an audio data transmission apparatus that encodes and transmits 3D audio signals and reproduction information, and a reception apparatus that decodes and renders these signals based on the received information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional audio transmission methods are used in VR/AR systems, then device complexity is reduced, but audio quality and immersion are insufficient
Solution Approach 1:
The audio data is segmented into multiple channels corresponding to different spatial positions and transition effects. Each channel carries specific audio information for particular directions or movement patterns, allowing the system to achieve high-quality 3D audio reproduction without requiring overly complex processing at each stage.
Solution Approach 2:
The patent transitions from conventional 2D audio transmission to 3D spatial audio by adding dimensional information about position and transition effects. Audio data is encoded with spatial coordinates and transition parameters, enabling the receiver to reconstruct immersive three-dimensional sound fields that match the virtual environment.
2Adaptability or versatility
If audio data with transition effects is transmitted, then user immersion is improved, but data transmission complexity increases
Solution Approach 1:
Transition effect information and spatial audio data are pre-encoded and packaged together during the content creation phase. This preliminary preparation includes embedding position information, transition parameters, and effect data into the audio stream, so that the receiving device can directly decode and render immersive audio without requiring complex real-time processing.
3Manufacturing precision
If high-quality 3D audio data is transmitted, then spatial sound reproduction is improved, but transmission efficiency decreases
Solution Approach 1:
The patent employs parameter-based encoding where audio characteristics are represented by a set of spatial parameters rather than full-waveform transmission. By changing the representation from time-domain waveforms to parameter-domain descriptors (position, transition effects, spatial relationships), the system achieves high-fidelity 3D audio reproduction with reduced data rates and improved transmission efficiency.
