SUNNYVALE, Calif. — July 15, 2009 — Harmonic Inc. (NASDAQ: HLIT) and Audible Magic have teamed up to integrate Audible Magic's audio and video fingerprint creation tools with Harmonic's Rhozet™ Carbon Coder™ universal media transcoding solution. This solution will simplify the process for copyright owners to register, at no cost, their audiovisual content with Audible Magic. Once registered, copyright owners can quickly and easily begin protecting, tracking, and monetizing their online content.

In addition to protecting the rights of content owners, Audible Magic's patented fingerprint technology delivers multiple benefits enabling content owners to realize profits based on usage. Digital service providers that license online content can take advantage of Audible Magic's solutions to increase advertising revenues and click-to-buy opportunities, thereby increasing royalties back to content owners.

"Video content owners have told us that they need a quick and efficient method for generating and registering fingerprints of their content," said Vance Ikezoye, co-founder and CEO of Audible Magic. "By integrating our fingerprint technology with Rhozet Carbon Coder, which has established a well-earned reputation for performance, we are able to provide a rapid and easy solution to meet their needs."

"Content owners are entitled to protect their copyrighted material and to realize profits from the use of that material," said David Trescot, vice president of the Rhozet Business Unit at Harmonic Inc. "By registering their content with Audible Magic, one of the leaders in content ID, Carbon Coder customers can better combat on-line piracy and move forward in a positive manner to enable revenue-generating, legal use of their content."

As part of the transcode process, Carbon Coder handles an array of critical operations including SD/HD and PAL/NTSC conversion, logo insertion, color space conversion, color correction, and closed captioning extraction. Multiple Carbon Coder nodes can be configured as a rendering farm to accelerate the workflow and provide automated processing for high-volume transcoding.
