Imagine Communications’Converged VOD andSDV Network Architecture
Imagine has launched an SDV solutionincorporating VBR/StatMux, enabling bettervideo quality and greater bandwidthefficiency (up to 50 percent). Imagine’s SDVsystem comprises the SDV staging processorand the QOD gateway. The SDV stagingprocessor provides much better video qualitythan current clamping devices, according tothe company. With the optional addition ofthe QOD gateway, 15 SDV signals can bestatistically multiplexed within a 256-QAMchannel with digital broadcast quality.
Both products incorporate Imagine’ssoftware on carrier-grade, off-the-shelfhardware, plug seamlessly into existing SDVinfrastructure, and are compatible withcentralized bulk encryption.

Motorola’s Switched Digital Video ArchitectureFrom the headend to the home, Motorola Connected Home Solutions offers standards-based, end-to-end solutions that allow cable operators to
deploy switched digital video services to reclaim bandwidth, delay or postpone plant rebuilds, and deliver a wider range of content. The companyoffers a turnkey solution that can be integrated with existing infrastructure to provide cable operators with the flexibility to offer additionalchannels that only consume bandwidth when they are actually being watched. Motorola also provides professional services to help support SDVdeployments and help cable operators implement best practices for deploying and managing SDV.
Faced with the need to carve out more bandwidth for HDTV, faster high-speed data services, video-on-demand, andother advanced services, cable operators are turning to a variety of tools to make the most of their existingcapacity. One of the tools for packing more into the existing spectrum is switched digital video (SDV), which gives
operators the power to dole out video content as subscribers request it.
Because less-frequently-viewed video channels are transmitted only when subscribers ask for them, and not broadcastto all subscribers all of the time, SDV offers the promise of a virtually unlimited channel lineup. As an added benefit, itis often cited as one of the least expensive ways to expand bandwidth.
SDV also allows operators to offer more niche content, without committing dedicated bandwidth to each specialinterest channel. As a reference, here’s a sampling of SDV architectures.
