Harmonic`s Rhozet Video Transcoding Technology Facilitates Creation of Trackable Content for Arbitron

- Rhozet Carbon Coder to Play Important Role in Arbitron`s Media Research
Services -
LAS VEGAS--(Business Wire)--
Harmonic Inc. (NASDAQ:HLIT) today announced that its Rhozet Carbon Coder
universal transcoding technology has been selected by Arbitron for use in its
media research services. The integration of Rhozet Carbon Coder with Arbitron
audience measurement technology will provide media companies with a seamless
method to watermark content during the transcode process so that it can be
measured and included in Arbitron`s media research services.

"Our goal is to offer our customers new measurement solutions using our Portable
People Meter technology," said Taymoor Arshi, Chief Technology Officer at
Arbitron. "Our integration with Rhozet Carbon Coder helps by providing customers
with the ability to prepare their content within their current workflows for
inclusion in our media research services."

The Carbon Coder software will be used in production pipelines to embed an
inaudible code into the audio portion of entertainment and advertising content.
This code can be detected by the Arbitron Portable People MeterTM (PPM). The
PPMTM system uses a passive audience measurement device-about the size of a
small cell phone-that can track consumer exposure to encoded media and
entertainment, including broadcast, cable and satellite television; terrestrial,
satellite and online radio, as well as many types of place-based audio media.
Carried throughout the day by randomly selected survey participants, the PPM
device can track when, where, and how they are exposed to encoded media and
entertainment.

"A critical aspect of media is understanding when and how viewers are seeing or
hearing it," said David Trescot, Vice President of the Rhozet Business Unit at
Harmonic Inc. "Arbitron is a leader in providing such market information, and we
are pleased to be working with them on an integrated solution to facilitate the
creation of trackable content."

Rhozet Carbon Coder is a universal transcoding solution used by leading media
companies including Ascent Media Group, British Sky Broadcasting (BskyB),
Lifetime Networks and MTV. It facilitates the creation of multi-format video for
Internet, mobile and broadcast applications. 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.

The latest version of Carbon Coder will be demonstrated at NAB2009 in Las Vegas,
April 20-23, in the Rhozet booth #SL9728 and at the main Harmonic booth #SU7209.
