An Open Architecture for Switched Digital Services in HFC Networks

Abstract

Switched Digital Video (SDV) technology promises to fundamentally change how digital video is delivered over cable networks, enabling MSOs to offer consumers a wider variety of programming while effectively managing HFC network bandwidth. From a business perspective, SDV offers MSOs a number of key benefits. First, SDV is a cost-effective bandwidth management tool that immediately reduces HFC bandwidth requirements compared with traditional “linear” content delivery. Second, the SDV system bandwidth scales as a function of viewership rather than as a function of programs offered.
