ELECTRONIC DEVICE, METHOD, AND NON-TRANSITORY COMPUTER READABLE STORAGE DEVICE ADAPTIVELY PROCESSING AUDIO BITSTREAM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18483506 titled 'ELECTRONIC DEVICE, METHOD, AND NON-TRANSITORY COMPUTER READABLE STORAGE DEVICE ADAPTIVELY PROCESSING AUDIO BITSTREAM
Simplified Explanation
The abstract describes a patent application for an electronic device that can enhance audio quality based on the bitrate of the audio signal received.
- The processor in the device identifies the bitrate of the incoming audio signal.
- If the bitrate is lower than a reference value, the processor executes a bandwidth extension (BWE) to improve the audio quality.
- The BWE is based on coding parameters obtained from a previously received audio signal.
- If the bitrate is higher than or equal to the reference value, the audio signal is obtained without executing the BWE.
- The device outputs the enhanced audio signal through a speaker.
Potential Applications
This technology could be applied in various electronic devices such as smartphones, tablets, and laptops to improve audio quality for users.
Problems Solved
This technology solves the problem of low-quality audio signals due to low bitrates, providing users with a better listening experience.
Benefits
The benefits of this technology include enhanced audio quality, improved user experience, and the ability to adapt audio processing based on bitrate.
Potential Commercial Applications
One potential commercial application of this technology could be in the development of high-quality audio devices for consumers who value superior sound performance.
Possible Prior Art
Prior art in audio signal processing and bandwidth extension techniques may exist, but specific examples are not provided in this abstract.
Unanswered Questions
How does the bandwidth extension process work in detail?
The abstract mentions the execution of a bandwidth extension process to enhance audio quality, but it does not provide specific details on how this process is carried out.
What coding parameters are used for the bandwidth extension?
The abstract mentions obtaining coding parameters from a previously received audio signal for the bandwidth extension process, but it does not specify what these parameters are or how they contribute to improving audio quality.
Original Abstract Submitted
An electronic device includes a communication circuit, a speaker, and a processor. The processor is configured to identify a bitrate of a first audio bitstream received via the communication circuit from an external electronic device. The processor is configured to obtain, in response to the bitrate lower than a reference value, an audio signal by executing a bandwidth extension (BWE) for the first audio bitstream based on at least one coding parameter obtained from a second audio bitstream previously received via the communication circuit from the external electronic device before the first audio bitstream. The processor is configured to obtain, in response to the bitrate higher than or equal to the reference value, the audio signal for the first audio bitstream without executing the BWE. The processor is configured to output, based on the audio signal, audio via the speaker.
