Microsoft and Harmonic Integrate Encoding and IPTV Solutions to Help Speed Telco TV Deployments and Market Growth

CHICAGO June 7, 2005 SUPERCOMM 2005, BOOTHS 29066 and 29035 — Microsoft Corp. (Nasdaq: “MSFT”) and Harmonic Inc. (Nasdaq: HLIT) today announced they are jointly working to deliver an integrated Internet protocol (IP)-based video solution encompassing the Microsoft® TV IPTV Edition software platform and Harmonic’s industry-leading DiviCom® encoding solutions. The integration, which represents one of the first real-time IPTV solutions for both SMPTE VC-1 and MPEG-4 AVC (H.264), enables broadband service providers to offer feature-rich, broadcast-quality video services at ultra-low bit-rates. The collaboration — formalized through a Development Cooperation Agreement — is expected to speed service deployments while reducing technical risk, and to facilitate the growth of the emerging IPTV market. The agreement allows for the continued integration and interoperability testing of the two companies’ solutions using the DiviCom MV 100 multi-codec real-time compression platform.

The collaboration between Microsoft and Harmonic will benefit telcos and other communication service providers seeking to extend their customer relationships by provisioning a compelling suite of broadcast and on-demand services over bandwidth-sensitive networks. By providing a comprehensive solution for transmitting high-quality video services at very low bit-rates, the two companies further facilitate the delivery of competitive TV services over xDSL and other IP-based networks. This new agreement builds on a relationship initiated in September 2003 to promote the Windows Media® 9 Series codec now known through the SMPTE standardization process as VC-1 for broadcast-grade video services on Harmonic’s DiviCom MV 100 encoding platform.

As part of the collaboration agreement, Harmonic will support important new IPTV features such as a mosaic program guide and picture-in-picture viewing. Supporting such features and capabilities at the head end rather than at the edge application server will result in a superior viewing experience with faster processing and better overall picture quality.

“High-quality, real-time VC-1 and AVC encoding is a critical component in the end-to-end delivery of IPTV services from Microsoft TV,” said Phil Corman, director of worldwide partner development of the Microsoft TV Division at Microsoft Corp. “Harmonic’s advanced encoding capability and video-over-IP expertise, combined with our robust IPTV software platform, make it possible for operators to utilize IP-based networks to deliver a range of next-generation television services and a viewing experience that is second to none. This is a critical requirement for growing the IPTV subscriber base.”

“The expansion of the relationship between Microsoft and Harmonic is a very significant step in the evolution of commercially viable IPTV and broadband video services,” said David Price, vice president of Business Development for the Convergent Systems Division of Harmonic. “Broadband operators can now overcome existing bandwidth limitations to offer a competitive TV service with compelling viewing features and more channels of high-quality video. We expect this to be a welcome development from both new and existing customers, and should serve to accelerate the roll-out of IP-based television services.”

The improved compression efficiencies of advanced codecs coupled with the processing power and unique technology of Harmonic’s DiviCom MV 100 will greatly reduce video bit-rates while maintaining broadcast-quality pictures. This makes it possible for operators to extend the reach of their services, efficiently utilize bandwidth to deliver more services, and reduce both deployment and operational costs. The MV 100 supports MPEG-2 in addition to VC-1 Advanced Profile and MPEG-4 AVC to enable a broad array of existing and emerging applications as well as to provide operators great choice and flexibility over the long-term. Harmonic’s MV 100 is the world’s first and remains the only real-time MPEG-4 AVC video encoder to power a commercial (revenue-generating) AVC-based broadcast IPTV service for a telco.

Microsoft TV IPTV Edition is a comprehensive software platform that allows broadband service providers to deliver compelling digital TV services using their existing IP networks. Leading service providers worldwide are conducting trials or planning to deploy IPTV services based on the Microsoft TV IPTV Edition platform.

About the DiviCom MV 100 Real-time Encoding Platform

The DiviCom® MV 100 real-time encoding platform delivers compression efficiencies and video quality that redefine the meaning of ultra-low bit-rate encoding for MPEG-2, MPEG-4 AVC (H.264) and SMPTE VC-1. The MV 100’s software architecture and processing power enable operators to easily accommodate changing market requirements through field installable features and functional enhancements, performance improvements, and even a more capable codec. Since its introduction in late 2003, the MV 100 has been deployed by telco, cable, satellite and terrestrial broadcasters for innovative applications — such as the world’s first MPEG-4 AVC-based TV-over-DSL service and cable digital simultrans — to become the leading multi-codec-capable, real-time video encoder. Today, MV 100 encoders in use around the globe are delivering thousands of free and pay-TV services to tens of millions of viewers.
