BigBand Networks is set to demonstrate new switched digital video (SDV) technologies at the National Cable & Telecommunications Association's (NCTA) The Cable Show '08, being held May 18-20 in New Orleans.

SDV sends just the programming that is being watched in a service group, instead of the entire slate of a cable operators’ lineup, which allows MSOs to reclaim bandwidth for other services, such as adding more high-definition (HD) channels.

To date, BigBand has deployed its SDV products in more than 20 cable systems across North America. Charter, Cox Communications, Time Warner Cable, Cablevision and Comcast are among BigBand’s SDV customers.

Demonstrations will include QualityShaping VBR, a SDV enhancement that can provide up to 50 percent more channel capacity; IPTV over SDV, which utilizes SDV network equipment and management systems for a more cost-effective delivery of video to TVs and PCs via DOCSIS networks; advanced advertising, which will highlight the ability of switched unicast to forward specific ads; and switched video analysis, which allows operators to improve bandwidth efficiency, capacity planning, monitoring and troubleshooting capabilities.

BigBand will be showing off the technologies at Booth #2013, and the company will also present two co-authored white papers at the NCTA Technical Paper conference.
