APPARATUS FOR ENCODING AND DECODING AUDIO SIGNALS AND METHOD OF OPERATION THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240233738 titled 'APPARATUS FOR ENCODING AND DECODING AUDIO SIGNALS AND METHOD OF OPERATION THEREOF
Simplified Explanation: The encoding apparatus described in the patent application is a device that can process audio signals by embedding signal components from one frequency band into another, generating additional information related to these frequency bands, encoding the modified audio signal, and formatting it into a bitstream.
- The apparatus can obtain an input audio signal.
- It generates an embedded audio signal by mixing signal components from a second frequency band into a first frequency band of the input audio signal.
- Additional information is created for the first and second frequency bands.
- The embedded audio signal is encoded.
- The encoded audio signal and additional information are formatted into a bitstream.
Key Features and Innovation:
- Signal embedding and encoding capabilities.
- Generation of additional information related to frequency bands.
- Bitstream formatting for efficient data transmission.
Potential Applications: This technology can be used in audio processing applications, such as audio watermarking, data hiding, and audio compression.
Problems Solved: This technology addresses the need for efficient audio signal processing, embedding, and encoding.
Benefits:
- Enhanced audio signal processing capabilities.
- Improved data transmission efficiency.
- Increased security through embedded information.
Commercial Applications: The technology can be applied in industries such as telecommunications, broadcasting, digital media, and security systems for audio data processing and transmission.
Questions about the Technology: 1. How does the apparatus differentiate between the first and second frequency bands during signal embedding? 2. What are the potential limitations of embedding signal components from one frequency band into another?
Original Abstract Submitted
provided is an encoding apparatus including a memory configured to store instructions and a processor electrically connected to the memory and configured to execute the instructions, wherein the processor may be configured to perform a plurality of operations, when the instructions are executed by the processor, wherein the plurality of operations may include obtaining an input audio signal, generating an embedded audio signal by embedding signal components of a second frequency band of the input audio signal in a first frequency band of the input audio signal, generating additional information associated with the first frequency band and the second frequency band, generating an encoded audio signal by encoding the embedded audio signal, and formatting the encoded audio signal and the additional information into a bitstream.
