WATERMARK-BASED AUDIO PROCESSING METHOD AND AN AUDIO PLAYER UTILIZING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240282302 titled 'WATERMARK-BASED AUDIO PROCESSING METHOD AND AN AUDIO PLAYER UTILIZING THE SAME

Simplified Explanation: This patent application describes a method for watermark-based audio processing in an audio player system.

• The receiver receives an audio input signal.
• The analog-to-digital converter converts the audio input signal into a digital input signal with a keyword.
• The processor detects the energy of the digital input signal.
• If the energy exceeds a threshold, the processor checks for a watermark in the signal.
• If no watermark is found, the processor embeds a watermark into a predefined digital audio signal to generate a digital output signal.
• The digital-to-analog converter converts the digital output signal into an audio output signal.
• The transmitter outputs the audio signal for playback.

Key Features and Innovation:

• Detection of energy levels in the digital input signal.
• Embedding watermarks into audio signals to prevent unauthorized use.
• Integration of watermarking technology into audio player systems.

Potential Applications:

• Digital rights management in audio playback devices.
• Preventing unauthorized distribution of audio content.
• Enhancing security in audio transmission.

Problems Solved:

• Unauthorized copying and distribution of audio content.
• Ensuring the integrity and authenticity of audio files.
• Protecting intellectual property rights in the audio industry.

Benefits:

• Enhanced security for audio content.
• Prevention of piracy and unauthorized use.
• Improved control over the distribution of audio files.

Commercial Applications: Watermark-based audio processing technology can be used in:

• Music streaming services
• Online radio platforms
• Audio equipment manufacturers

Questions about Watermark-based Audio Processing: 1. How does watermarking technology enhance the security of audio content? 2. What are the potential implications of using watermark-based audio processing in the music industry?

Frequently Updated Research: Stay updated on advancements in digital watermarking technology and its applications in audio processing.

Original Abstract Submitted

a watermark-based audio processing method for use in the audio player including a receiver, an analog-to-digital converter, a processor, a digital-to-analog converter and a transmitter includes: the receiver receiving an audio input signal, the analog-to-digital converter converting the audio input signal into a digital input signal including a keyword, the processor detecting an energy of the digital input signal, if the energy exceeds a threshold, the processor determining whether a watermark is included in the digital input signal, if not, the processor embedding the watermark into a predefined digital audio signal to generate a digital output signal, then the digital-to-analog converter converting the digital output signal into an audio output signal, and finally, the transmitter outputting the audio output signal for playback.
