Dramatic Increase in North American Deployments Leads to Global Leadership
                                    Position

SAN JOSE, Calif. - Jan. 8, 2013 - Harmonic (NASDAQ: HLIT), the worldwide leader
in video delivery infrastructure, today announced that Multimedia Research Group
Inc. (MRG) has ranked Harmonic as the top global headend provider within its
annual IPTV market report. MRG's comprehensive study, "IPTV Market Leader Report
by Product and Region - Fall 2012," identifies the best IPTV systems and
software companies in six key product categories and geographical regions. The
ranking is based on the number of deployed IPTV   subscribers using a given
vendor's products and the calculated number of input channels for the IPTV video
headend segment. Harmonic video infrastructure solutions currently power 29.9
percent of IPTV service providers' headends worldwide, capturing an impressive
45.6 percent of the market share in Latin America, 53 percent in Western Europe,
and 28 percent in North America.

"After gathering data from more than 900 service providers and over 60 IPTV
vendors around the world, MRG has determined that Harmonic is the top global
headend solutions provider," said Jose Alvear, senior research analyst at MRG.
"This was an especially important achievement because Harmonic was the only
vendor in this year's report to move up and capture the top spot in our global
IPTV leader rankings."

Over the past two years, Harmonic's advanced IPTV headend solutions have been
deployed by more than 240 new telco customers and currently power over 12,000
channels in North America, helping the company surpass Google/Motorola as the
top video headend solutions provider worldwide. Harmonic video infrastructure
systems deliver exceptional video quality while optimizing operational
efficiencies through increased density and scalability. Recent customer wins
include Northeast Texas telecommunications provider ETEX Telephone Cooperative
and Ben Lomand Telephone Cooperative in Tennessee.

"While Harmonic has been the dominant IPTV headend solutions provider in Latin
America and Western Europe for years, recent technology advancements like
ProStream 1000 with ACEhave enabled us to make dramatic inroads in North
America," said Thierry Fautier, senior director of convergence solutions,
Harmonic. "Harmonic's innovative video infrastructure solutions resolve the most
pressing needs of IPTV service providers by delivering high-quality video
content - including value-added services like multiscreen - at reduced
operational expenses. The MRG data is a powerful confirmation of the strong year
that Harmonic had in 2012 and will continue to expand upon in the future."
