MULTI-CHANNEL AUDIO SIGNAL ENCODING METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18154451 titled 'MULTI-CHANNEL AUDIO SIGNAL ENCODING METHOD AND APPARATUS
Simplified Explanation
The patent application describes a method and apparatus for encoding multi-channel audio signals. Here is a simplified explanation of the abstract:
- The invention focuses on encoding audio signals of multiple channels in a multi-channel audio signal.
- The audio signals are divided into channel pairs, and the bit quantities for each channel pair are determined based on the energy/amplitudes of the audio signals and the available bits.
- The audio signals are then encoded based on the determined bit quantities to generate an encoded bitstream, resulting in improved encoding quality.
Potential applications of this technology:
- Audio streaming services: The improved encoding quality can enhance the audio experience for users streaming multi-channel audio content.
- Broadcasting: Broadcasting companies can utilize this technology to improve the quality of multi-channel audio signals transmitted over the airwaves.
- Virtual reality (VR): VR applications often require multi-channel audio, and this technology can help optimize the encoding process for a more immersive audio experience.
Problems solved by this technology:
- Efficient encoding: By determining the bit quantities based on the energy/amplitudes of the audio signals, the encoding process can be optimized, resulting in improved quality while utilizing the available bits effectively.
- Improved audio quality: The method and apparatus described in the patent application can enhance the encoding quality of multi-channel audio signals, leading to a better audio experience for listeners.
Benefits of this technology:
- Enhanced audio experience: The improved encoding quality can result in clearer and more immersive audio for users.
- Efficient use of available bits: By determining the bit quantities based on the energy/amplitudes of the audio signals, the encoding process can make the most efficient use of the available bits, optimizing the overall encoding quality.
