Destiny Media Gets Another Patent

DESTINY MEDIA TECHNOLOGIES has gotten approval for a second watermarking patent.
On JULY 19th, 2011, the U.S. PATENT AND TRADEMARK OFFICE (USPTO) issued a patent for Methods For Watermarking Media Data (http://tinyurl.com/7pjlp3a). Before this patent was granted, the company filed a continuation application with further claims. The USPTO has now indicated these new claims are allowable and the company expects a notice of allowance and a second watermarking patent to be granted. Corresponding patent applications are pending in CANADA, EUROPE and JAPAN.
The patented technique embeds an inaudible digital trace or watermark into the audio track and this trace survives duplication, filtering, down sampling and conversion into other formats, including non digital ones such as an over the air broadcast. Unlike competing watermarking solutions, it is faster to embed or detect and it is extremely robust without affecting audio quality.
