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 20240127835 titled 'ELECTRONIC DEVICE, METHOD, AND NON-TRANSITORY COMPUTER READABLE STORAGE DEVICE ADAPTIVELY PROCESSING AUDIO BITSTREAM
Simplified Explanation
The abstract describes an electronic device that can enhance audio quality by performing bandwidth extension on a received audio bitstream based on coding parameters from a previously received bitstream, depending on the bitrate of the incoming audio data.
- The device includes a communication circuit, a speaker, and a processor.
- The processor identifies the bitrate of the incoming audio data.
- If the bitrate is below a reference value, the processor executes bandwidth extension to improve audio quality.
- If the bitrate is equal to or higher than the reference value, the audio signal is obtained without bandwidth extension.
- The audio signal is then output through the speaker.
Potential Applications
This technology could be applied in various audio devices such as smartphones, tablets, and laptops to enhance the audio quality of received audio streams.
Problems Solved
This technology addresses the issue of low-quality audio streams by dynamically adjusting the audio signal based on the bitrate of the incoming data.
Benefits
The device provides improved audio quality for users, especially when receiving audio streams with lower bitrates.
Potential Commercial Applications
This technology could be integrated into audio devices for consumers who prioritize high-quality audio experiences, potentially increasing the market value of such products.
Possible Prior Art
One possible prior art could be the use of audio codecs that dynamically adjust audio quality based on the available bandwidth, but the specific implementation of bandwidth extension based on coding parameters from a previously received bitstream may be a novel aspect of this technology.
Unanswered Questions
How does the device determine the reference value for the bitrate threshold?
The abstract does not provide details on how the reference value for the bitrate threshold is determined. This information would be crucial in understanding the device's decision-making process for executing bandwidth extension.
What coding parameters are used from the second audio bitstream for bandwidth extension?
The abstract mentions using coding parameters from a previously received audio bitstream for bandwidth extension, but it does not specify which parameters are utilized. Understanding the specific coding parameters involved could provide insights into the effectiveness of the bandwidth extension process.
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.
