The Brainwave Audio and Video Encoding and Playing System is a patented innovation that converts human brainwave signals into personalized audio-visual content and interactive multimedia experiences. The invention has been granted patents in the United States (US 11,782,509 B1), Taiwan (I859542), and China (ZL 2022 1 0502954.7), demonstrating its originality, technical value, and international intellectual property protection.

This system integrates brainwave sensing, signal analysis, audio-visual encoding, and playback into one unified platform. By capturing and interpreting a user’s brainwave data, the system transforms neurophysiological signals into meaningful parameters that can generate or control music, images, videos, and immersive multimedia outputs. Unlike conventional media systems that depend mainly on manual input or fixed content, this invention enables digital media to reflect the user’s mental and emotional state.

The technology creates a new form of brainwave-driven human–computer interaction and supports applications in digital wellbeing, emotional awareness, meditation, education, creative media, immersive exhibitions, metaverse interaction, and personalized multimedia services.

Overall, this invention bridges neuroscience, artificial intelligence, and digital media, offering a novel, human-centered approach to transforming brain activity into meaningful audio-visual experiences with strong social, technological, and commercial potential.
