DETERMINATION OF SPATIAL AUDIO PARAMETER ENCODING AND ASSOCIATED DECODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18598219 titled 'DETERMINATION OF SPATIAL AUDIO PARAMETER ENCODING AND ASSOCIATED DECODING
Simplified Explanation: The patent application describes an apparatus that can receive an indicator to determine if spatial audio signal directional metadata parameters were encoded based on a specific quantization resolution. It can then decode the encoded metadata parameters accordingly.
- The apparatus can identify if the encoded metadata parameters were quantized based on a certain number of bits.
- It can decode the metadata parameters based on the quantization resolution indicated by the received indicator.
- If the metadata parameters were not encoded based on the specified quantization resolution, the apparatus can decode them using different methods for different parts of the data.
Key Features and Innovation:
- Ability to identify the quantization resolution used for encoding spatial audio signal directional metadata parameters.
- Decoding of metadata parameters based on the quantization resolution indicated by the received indicator.
- Different decoding methods for entropy encoded and fixed rate encoded metadata parameters.
Potential Applications: The technology can be used in:
- Audio processing systems
- Virtual reality and augmented reality applications
- Immersive audio experiences
Problems Solved:
- Efficient decoding of spatial audio signal directional metadata parameters.
- Ensuring accurate reproduction of spatial audio in various applications.
Benefits:
- Improved spatial audio quality.
- Enhanced user experience in audio applications.
- Efficient use of storage and bandwidth.
Commercial Applications: Title: Spatial Audio Decoding Apparatus for Enhanced Audio Experiences This technology can be utilized in:
- Audio software development
- Entertainment industry for immersive audio content creation
- Gaming industry for realistic audio effects
Questions about Spatial Audio Decoding Technology: 1. How does the apparatus determine the quantization resolution used for encoding the spatial audio signal directional metadata parameters? 2. What are the potential implications of this technology on the virtual reality industry?
Original Abstract Submitted
An apparatus for receiving an indicator configured to identify whether encoded spatial audio signal directional metadata parameters for time-frequency tiles of an audio frame were encoded based on a quantization resolution which is equal to or less than a determined number of bits; decode the encoded spatial audio signal directional metadata parameters for the time-frequency tiles of the audio frame based on the quantization resolution which is equal to or less than the determined number of bits when the indicator identifies as such; and when the indicator identifies that the encoded spatial audio signal directional metadata parameters were not encoded based on the quantization resolution which is equal to or less than the determined number of bits, decode a first part comprising entropy encoded spatial audio signal directional metadata parameters and decode a second part comprising fixed rate encoded spatial audio signal directional metadata parameters.
