Harmonic Inc : Virgin Media TV Anywhere Powered by Harmonic ProMedia(TM) Suite

  ProMedia(TM) Live and ProMedia Package Optimize Virgin Media's Multiscreen
      Workflow to Deliver 45 Live TV Channels to Subscribers in the U.K.

SAN JOSE, Calif. - March 19, 2013 - Harmonic (NASDAQ: HLIT), the worldwide
leader in video delivery infrastructure, today announced that Virgin Media,
the United Kingdom's leading provider of cable television, broadband, phone,
and mobile services, has deployed Harmonic's ProMedia(TM) family of integrated
software solutions to power an innovative new multiscreen service called
Virgin TV Anywhere. Harmonic's real-time multiscreen video processing and
encoding technology enables Virgin TV Anywhere customers to watch up to 45
live TV channels on a wide range of devices, including TVs, PCs, smartphones,
and tablets. Leveraging Virgin Media's powerful new infrastructure, customers
can also manage recorded programs and control TiVo^® set-top boxes through a
state-of-the-art Virgin TV Anywhere app.

Neil Drennan, director of TV engineering at Virgin Media said, "The world of
digital entertainment is moving fast and consumers are always looking for
compelling ways to take advantage of the connectivity built into today's
gadgets. Harmonic's ProMedia software solution optimizes our multiscreen
operational workflow, helping us put fantastic entertainment at our customers'

ProMedia Live transcodes MPEG-2 and MPEG-4 AVC H.264 content to multiple
high-quality adaptive bit-rate streams optimized for the Virgin TV Anywhere
service. By effectively handling metadata information - such as language,
captions, and ad insertion signaling - upon input and output, the ProMedia
family provides a complete video preparation solution. ProMedia Live is also
integrated with Harmonic's ProMedia Package to perform sophisticated
encapsulation and encryption processes from a unified management system. By
relying on a powerful integrated headend for its multiscreen services, Virgin
Media is now able to support Apple^® HLS and Adobe^® HDS streaming to a broad
range of customer devices.

Harmonic's NMX(TM) Digital Service Manager controls both ProMedia Live and
ProMedia Package systems, enabling Virgin Media to seamlessly monitor and
control its multiscreen video and audio services. Through a comprehensive user
interface, Virgin Media is easily able to create and modify network topology
and channel lineups, in addition to setting encoding parameters. The system's
highly scalable and extensible architecture will enable Virgin Media to easily
support hundreds of live television channels as well as introduce additional
services like start-over and catch-up TV.

"Harmonic has been Virgin Media's go-to technology partner for a variety of
high-profile television events and services over the years. With this latest
installation, we're excited to bring cutting-edge multiscreen services to
subscribers in the U.K.," said Ian Graham, vice president of sales, Europe,
the Middle East, and Africa, Harmonic. "Based on its integration, flexibility,
and scalability, Harmonic's award-winning ProMedia Suite is the industry's
trusted solution for high-quality multiscreen production and delivery."

Virgin Media's operations center also features existing Harmonic
infrastructure solutions that seamlessly work alongside the new ProMedia Suite
and NMX systems, including Electra^(TM) 8000 encoders, ProStream^® 1000
multiplexers, and NSG(TM) 9000 edgeQAMs for increased efficiency, reliability,
and scalability.

Harmonic will showcase its comprehensive range of next-generation multiscreen
production and delivery solutions at stand 85 during TV Connect in London,
March 19-21. Further information about Harmonic and the company's products is
