DETERMINATION OF SPATIAL AUDIO PARAMETER ENCODING AND ASSOCIATED DECODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240212696 titled 'DETERMINATION OF SPATIAL AUDIO PARAMETER ENCODING AND ASSOCIATED DECODING
Simplified Explanation: The patent application describes an apparatus that can decode spatial audio signal directional metadata parameters based on the quantization resolution used during encoding.
- The apparatus receives an indicator to determine the quantization resolution of the encoded spatial audio signal directional metadata parameters.
- If the indicator shows that the quantization resolution is equal to or less than a certain number of bits, the apparatus decodes the parameters accordingly.
- If the indicator indicates a different quantization resolution, the apparatus decodes the parameters in two parts: entropy encoded and fixed rate encoded.
Key Features and Innovation:
- Indicator-based decoding of spatial audio signal directional metadata parameters.
- Ability to decode parameters based on quantization resolution for efficient processing.
- Two-part decoding process for different encoding scenarios.
Potential Applications: The technology can be used in audio processing applications, virtual reality systems, gaming consoles, and multimedia content creation tools.
Problems Solved:
- Efficient decoding of spatial audio signal directional metadata parameters.
- Improved processing of audio signals with varying quantization resolutions.
Benefits:
- Enhanced audio quality in spatial audio applications.
- Optimized decoding process for better performance.
- Flexibility in handling different encoding scenarios.
Commercial Applications: The technology can be utilized in audio software development, virtual reality platforms, gaming devices, and streaming services to enhance the spatial audio experience for users.
Prior Art: Researchers can explore prior patents related to spatial audio signal processing, audio encoding techniques, and metadata parameter decoding in audio systems.
Frequently Updated Research: Stay updated on advancements in spatial audio processing, audio signal encoding, and metadata parameter optimization for audio applications.
Questions about Spatial Audio Signal Directional Metadata Parameters: 1. How does the apparatus determine the quantization resolution for decoding spatial audio signal directional metadata parameters? 2. What are the potential implications of using indicator-based decoding in spatial audio applications?
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.
