Switched Digital Video - DVB

Introduction

Move to Switched Digital Video


Cable operators face more competition than ever before from telecom companies that offer traditional video and from over-the-top players that stream Internet-based video to IP devices. To compete successfully, you must deliver more content and greater interactivity while building a flexible plant that can rapidly deliver new IP services that can best those of the over-the-top providers. Only a switched infrastructure can meet these requirements.

Gain Control of Bandwidth Efficiency


Switched Digital Video (SDV) is designed to make more efficient use of cable plant capacity by splitting different neighborhoods into "service groups" of typically 500 to 1000 homes. Then, cable plant capacity is dynamically assigned only for the channels being actively watched. This frees up capacity that you can use to deploy new services. To the user, the SDV channels are indistinguishable from the broadcast channels they are accustomed to viewing.

Cisco offers a complete, end-to-end Switched Digital Video (SDV) solution. Together with SciCare Services, Cisco provides customized solutions, based on best-in-their-product-category Cisco and third-party components, that help ensure the interoperability, quality, and performance of your video services.

SciCare Services

SciCare Services fully manage the launch of your video services, on time and on budget. SciCare integrates high-quality components with the necessary services and takes full responsibility for the overall solution including any needed third-party components. An experienced team of certified project managers and engineers manages each implementation. SciCare Services maintain the day-to-day health of the network in the operate and optimize phases and achieve operational excellence through ongoing improvements.


Universal Session and Resource Manager

Universal Session Resource Manager (USRM) is a distributed services management platform that provides carrier-class signaling and resource management with always-on operation. It supports both table-based and session-based Cisco and third-party quadrature amplitude modulation (QAM) products. USRM uses open protocols for rapid deployment of new services or edge resources and can be configured to meet your architectural needs.


Cisco Digital Content Manager

Cisco Digital Content Manager processes SDV streams. In the SDV solution, it can perform additional functions with digital video, including rate limiting, component processing, ad insertion, and security (digital video broadcast scrambling).


Switched Digital Video Manager

Switched Digital Video Manager controls and arbitrates bandwidth for multiple applications. It manages allocation of bandwidth between SDV and existing video-on-demand (VoD) services.


Session-Based Quadrature Amplitude Modulators

Cisco offers a family of edge QAMs that support SDV. The Cisco Continuum DVP eXtra Dense QAM Array 24 (XDQA-24) and RF Gateway 1 are deployable into the SDV architecture. They also allow QAM sharing between SDV and VOD services.


Cisco CRS-1 Carrier Routing System

The industry's first carrier-class routing system transparently scales to 92 terabits per second to meet the extreme capacity needs of video entertainment delivery today while providing investment protection for the future.

Open Architecture for Distinctive Flexibility

Every element of the Cisco SDV solution is based on an open IP architecture for distinctive flexibility and advantage. This important differentiator opens up protocols for multiple vendor technologies and applications (including client software, servers, switches, and quadrature amplitude modulation [QAM ] products) integrated together for platform scalability and flexibility without complex upgrades. The SDV platform also immediately enables QAM video sharing and high network redundancy.

With the Cisco SDV solution, you can:

• Reclaim bandwidth spectrum while continuing to meet existing service demands

• Deliver new services, including more high-definition channels and new long-tail content, without any change to the viewer experience from traditional linear video

• Offer more content and advanced services to subscribers, including advanced advertising

• Establish a next-generation switched network architecture

• Improved visibility into subscriber behavior

• Implement QAM sharing to yield efficiency gains between video-on-demand and SDV sessions


From headend applications to content acquisition to set-tops, with support software for service assurance, the Cisco SDV solution provides a comprehensive package. You have the added benefit of a dedicated team of professionals with more than 25 years of interactive video experience.
