BigBand Networks to Demonstrate Advanced Video Services, Unveil New Deployment Milestones at Cable-Tec Expo.

Universal Edge QAM, CTO Roundtable to Highlight Company's Demonstrations and Presentations at SCTE Conference

REDWOOD CITY, Calif. -- BigBand Networks, Inc. (NASDAQ:BBND) today announced that it will demonstrate a series of key technologies and present in several technical sessions at SCTE's Cable-Tec EXPO 2007. The company will also provide updates on its groundbreaking commercial deployments of switched digital video and Modular CMTS (M-CMTS). BigBand will be located in Booth 2164 at the conference, which takes place Wednesday, June 20-Friday, June 22, at the Orlando Convention Center.

BigBand experts will present during multiple conference programs, including a lead panel in the Expo's opening session and two subsequent technical sessions. Presentation details, including date and time information, are included below:

* BigBand chief technology officer and co-founder Ran Oz will join executives from Comcast, Time Warner Cable and Suddenlink to exchange views on the future of cable technology during the CTO panel, scheduled to take place during the opening general session Wednesday, June 20th, from 10:15-11:45 a.m.

* Howard Abramson, BigBand's director of advanced engineering and development, will provide a roadmap for the evolution to IPTV over DOCSIS([R]) 3.0 and M-CMTS in his presentation for the panel entitled, "DOCSIS 3.0 Technologies & Services." The panel is scheduled for Thursday, June 21st at 9:30 a.m., and again at 11:00 a.m.

* Ron Wolfe, BigBand's senior product marketing manager, will walk through lessons learned from switched digital video deployments during the session, "Installing and Monitoring Switched Digital Video." The panel is scheduled for Thursday, June 21st at 11:00 a.m. and again on Friday, June 22nd at 1:30 p.m.

BigBand's technology demonstrations at Cable-Tec EXPO will include:

* Universal Edge QAM. As part of this demonstration, BigBand's Edge QAM platform shares capacity among on-demand and video-over-DOCSISservices and improves the utilization of QAM assets. The Edge QAM plays a pivotal role in a range of advanced video and data services, including VOD, switched digital video and Modular CMTS.

* Switched Digital Video Ecosystem. BigBand pioneered switched digital video and is the commercial deployment leader, with approximately 6.5 million households passed. BigBand's open solution is also interoperable with a wide array of set-top boxes, electronic programming guides and middleware. This demonstration illustrates the range of components that interoperate with BigBand's switched digital video solution.

* HDTV over DOCSIS([R]). This demonstration illustrates how cable operators can leverage three key attributes of BigBand's M-CMTS architecture to cost-effectively deliver HDTV over cable modems. The first attribute is BigBand's ability to deliver downstream channels at one fourth the cost of current integrated CMTS channels via M-CMTS technology. The second attribute is BigBand's unique ability to support new DOCSIS 3.0 channel bonding modems and existing DOCSIS modems simultaneously on the same downstream channels. This duality allows operators to continue to leverage their existing installed cable modem base to achieve data rates in the 20-30 megabits-per-second (Mbps) range, and simultaneously leverage channel bonding modems to offer data services of 100 Mbps or greater. The third attribute -- bandwidth-sharing of Edge QAMs between the CMTS and video services -- can drive down the delivery costs for higher bandwidth services.

* Switched Video Analysis. Switched video analysis highlights the ability of BigBand's switched digital video solution to gather metrics that allow service providers to make informed decisions about programming expansion and network utilization, as well as determine when and where to roll out new programming and advertising to improve viewer satisfaction and engagement.

* Addressable Advertising. This demonstration illustrates how advertisers can effectively target, execute and measure successful campaigns with advertising that more closely matches the interests of viewers.
