Harmonic's Encoders Power ATSC Mobile DTV Demonstration with Sinclair; Latest Generation Technology Frees Up Bandwidth and Delivers High Quality Mobile Video

Harmonic Inc. (NASDAQ: HLIT) today announced that its market-leading DiviCom® encoders and ProStream™ 4000 multi-screen platform will power ATSC Mobile DTV technology demonstrations at NAB 2009. The DiviCom Electra® 8000 universal broadcast encoder, Harmonic’s newest and most advanced platform, offers a powerful design that reduces bit-rates without compromising video quality, enabling broadcasters to free up valuable spectrum for advanced services such as mobile video delivery. Harmonic’s ProStream™ 4000 provides real-time video compression optimized for the ATSC Mobile DTV format suitable for delivery to mobile devices.

Harmonic’s solutions will be featured as part of demonstrations of live mobile video from Sinclair’s KVCW-TV signal in Las Vegas, at Sinclair Broadcast Group’s booth #C8546N, Acrodyne’s booth #C1336 and Harmonic’s booth #SU7209. The NAB show will be held in Las Vegas from April 20-23.

“The ATSC Mobile DTV standardization effort and the work of the many partners involved in our NAB technology demonstration has resulted in a powerful solution enabling broadcasters to deliver high quality mobile video services,” said Mark Aitken, Director, Advanced Technology for Sinclair Broadcast Group. “It was important for us to promote a best-in-class ecosystem for this emerging mobile technology, and Harmonic has again set a new benchmark for performance with its industry leading encoding and transcoding solution.”

To help assure optimal performance, Harmonic has also been working closely with LG Electronics, co-developer of the ATSC mobile digital TV system (now an ATSC Candidate Standard). LG and its U.S. R&D subsidiary Zenith have provided valuable technical assistance in the development of ATSC Mobile DTV capabilities in Harmonic’s world-class encoders.

“Mobile video is clearly an area that gives broadcasters an opportunity to enhance their service offering, and Harmonic’s comprehensive portfolio of solutions enables a high quality multi-screen video experience, whether broadcast or on demand,” said Tom Lattie, Director of Broadcast and New Media Solutions for Harmonic. “The Electra 8000 encoder represents the most advanced broadcast compression technology available, and the ProStream 4000 enables operators to transcode or encode to a variety of mobile and Internet video formats, including ATSC Mobile DTV. In addition to real-time compression, Harmonic’s MediaPrism™ software suite of aggregation tools is ideal for the repurposing of broadcast video content for new on-demand consumption models, such as Internet and mobile video.”
