BigBand Broadband Edge QAM (BEQ). Our Broadband Edge QAM platforms are used to convert digital video and data streams into quadrature amplitude modulated (QAM) RF streams that transport video and data across cable networks to subscriber set top boxes and cable modems. The services that are transported can include Switched Digital Video, Video on Demand, Broadcast Video and DOCSIS High Speed Data. Our QAM platforms are modular and employ digital signal processors, FPGAs and our own proprietary RF technology and algorithms. They are noted for their high signal quality and thermal efficiency.
BigBand Media Services Platform (MSP1200, 2000, 2800). Our Media Services Platform is designed to manage large numbers of IP video streams combined with rich media processing to enable a range of personalized video applications such as linear, zoned, and addressable advertising. Our MSP chassis-based platforms are designed to provide carrier-class reliability, scale and flexibility, including the ability to grow subscriber services and new applications over time with the addition of new hardware line cards. The BigBand MSP platforms are based on industry standards, open interfaces and established network protocols to simplify the platform integration into existing service provider networks.
In October 2010, we announced our new applications for the MSP platform within the cable market. The MSP-based QAM is the industry leading platform designed to enable service providers to cost-effectively scale and optimize the edge with dynamic bandwidth agility on the entire 50MHz to 1GHz RF spectrum.
Converged Video Exchange (CVEx). Our CVEx platform is a control plane solution designed to manage large numbers of video sessions while optimizing network bandwidth utilization. The CVEx platform is a fundamental component of our Switched Digital Video deployments and offers Edge Resource Manager (ERM) functionality to share QAM capacity across different network services. In addition, CVEx serves as the control plane for our vIP PASS solution to deliver managed IP video services with high performance and cost effectively across video QAMs.
Customers
We sell our products to cable MSOs and telecommunications companies worldwide, both directly and through resellers. In the U.S., our products are deployed by seven of the ten largest service providers. Our significant customers for 2010 were as follows:
Bright House Networks Comcast Sugys Cable ONE Cox Communications Time Warner Cable Charter Communications Ssangyong Verizon
A substantial majority of our sales have been to a limited number of large customers. However, our large customers have changed over time. Sales to our five largest customers represented 74%, 78% and 81%, respectively, of our net revenues for the years ended December 31, 2010, 2009 and 2008. In 2010, Cox Communications, Time Warner Cable and Verizon each represented 10% or more of our net revenues. In 2009, Charter Communications, Time Warner Cable and Verizon each represented 10% or more of our net revenues. In 2008, Cox Communications, Time Warner Cable and Verizon each represented 10% or more of our net revenues. Although we are attempting to broaden our customer base by penetrating new markets and expanding internationally, we expect that for the foreseeable future, a limited number of large customers will continue to comprise a large percentage of our revenues. International sales represented 9%, 11% and 9%, respectively, of our net revenues for the years ended December 31, 2010, 2009 and 2008.
