Destiny Media Technologies, the Vancouver-based creator of a new cross platform video streaming format, is pleased to announce approval for a second watermarking patent. On July 19, 2011, the US Patent and Trademark Office (USPTO) issued patent No. 7983441 entitled Methods For Watermarking Media Data.
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.
This will be the company’s third granted patent. Destiny also has a patented locking technology Digital Media Distribution Method and System (7466823) that is compatible with peer to peer networks, but still locks content to only play on authorized computing devices. These patented solutions give the content owner the choice of locking content, so it can’t be copied or allowing copies, but protecting those copies with a watermark to identify unauthorized duplication.
