Switched Digital Video Architectures
Faced with the need to carve out more bandwidth for HDTV, faster high-speed data services, video-on-demand, and other advanced services, cable operators are turning to a variety of tools to make the most of their existing capacity. 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 broadcast to all subscribers all of the time, SDV offers the promise of a virtually unlimited channel lineup. As an added benefi t, it is 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 special interest channel. As a reference, here’s a sampling of SDV architectures.

Motorola’s Switched Digital Video Architecture – For More HD!t
From the headend to the home, Motorola’s Home & Networks Mobility business offers standards-based, end-to-end solutions that allow cable operators to deploy switched digital video services to reclaim bandwidth and deliver a wider range of high defi nition (HD) content. The company offers a bandwidth effi ciency solution that allows operators to create a broadcast tier for content with wide appeal and switched “niches” to offer subscribers access to highly focused digital content channels without the need to commit dedicated bandwidth to these channels. This enables operators to deliver more of the HD content that consumers are demanding, Video on Demand (VOD), and availability of greater numbers of channels while offering consumers more choice in programming. When Motorola’s professional services are engaged we ensure cable operators implement SDV following best practices and are engaged for the initial design to post deployment ensuring a smooth transition once launched.

Cisco’s Open IP Architecture for Switched Digital Video
Cisco is a leader in delivering the Open IP Architecture that enables cable operators to switch MPEG video effi ciently today and support next-generation services in the future. Cable operators have already deployed this architecture, developed through collaboration between industry leaders and Cisco. This open architecture is based on IP Multicast protocols and open interfaces to the QAM, SDV server, SDV manager and the client. Benefi ts of an open platform include scalability, manageability and cost effectiveness, plus QAM sharing. The com-pany’s SDV solution offers specifi c value-added features, including intelligent bandwidth management, session resiliency and server redundancy.

Harmonic’s End-to-End Video Delivery for SDVHarmonic’s end-to-end video delivery platform for switched digital video (SDV) applications encompasses the ProStream 1000 stream
processing platform for re-encoding, the ProStream 2000 splicer, StreamLiner VOD/ad servers and the market-leading NSG universal edgeQAM. Compliant with industry standards, Harmonic’s IP-based systems provide a clear demarcation between the video delivery platform and the SDV back-offi ce, enabling the cable operator to deploy best-of-breed components.
The Harmonic SDV solution effi ciently addresses the biggest issues faced in switched architectures — channel change time and video quality. GOP regeneration enables faster and more predictable channel change time, and the decode/re-encode capabilities of the ProStream 1000 lever-age Harmonic’s outstanding video compression technology to deliver high quality video. The versatile Harmonic solution also makes it possible to reduce costs by leveraging the existing VOD architecture. The NSG 9000 edgeQAM can be shared between SDV and VOD sessions, and the ProStream 1000 can be used to feed the SDV network and video servers for network PVR, Start Over and Catch Up TV applications.
