METHODS AND APPARATUS TO PERFORM AUDIO WATERMARKING AND WATERMARK DETECTION AND EXTRACTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240257818 titled 'METHODS AND APPARATUS TO PERFORM AUDIO WATERMARKING AND WATERMARK DETECTION AND EXTRACTION
The patent application describes methods and apparatus for audio watermarking, detection, and extraction.
- Selecting frequency components to represent a code
- Using different sets of frequency components to represent different information
- Locating respective frequency components in code bands with equal or less spacing
- Synthesizing frequency components to represent the code
- Combining synthesized frequency components with an audio block
- Outputting the audio signal and an associated video signal
Potential Applications: - Copyright protection for audio content - Digital rights management - Anti-piracy measures in the music industry
Problems Solved: - Preventing unauthorized distribution of audio content - Ensuring proper attribution of intellectual property - Protecting artists' rights in the digital age
Benefits: - Enhanced security for audio files - Traceability of copyrighted material - Improved control over distribution channels
Commercial Applications: - Music streaming platforms - Online content distribution services - Audio production software companies
Questions about Audio Watermarking: 1. How does audio watermarking differ from traditional copyright protection methods? 2. What are the key challenges in implementing audio watermarking technology effectively?
Frequently Updated Research: - Ongoing studies on the effectiveness of audio watermarking in preventing piracy - Research on the development of advanced algorithms for robust watermark detection and extraction.
Original Abstract Submitted
methods and apparatus to perform audio watermarking and watermark detection and extraction are disclosed. example apparatus disclosed herein are to select frequency components to be used to represent a code, different sets of frequency components to represent respectively different information, respective ones of the frequency components in the sets of frequency components located in respective code bands, there being multiple code bands and spacing between adjacent code bands being equal to or less than the spacing between adjacent frequency components in the code bands. disclosed example apparatus are also to synthesize the frequency components to be used to represent the code, combine the synthesized frequency components with an audio block of an audio signal, and output the audio signal and a video signal associated with the audio signal.
