SIPV Platform Frees MSOs to Pursue DOCSIS Expansion without Upgrades

Accelerating Adoption of Adara Solution Underscores Game-Changing Impact on Broadband & TV Strategies


Growing numbers of cable MSOs are ensuring they’ll have all the bandwidth they need for DOCSIS expansion now and for years to come by deploying a switched video platform that far outperforms much costlier approaches to increasing broadband access rates.

Pioneered by Adara Technologies, Switched IP Video (SIPV) is enabling MSOs large and small to implement DOCSIS bandwidth expansion with unprecedented flexibility, speed and performance while freeing them to add unlimited numbers of HD and, in the future, UHD channels, with no disruption to subscribers. Their successes are providing convincing evidence that by revamping and repurposing the SDV (switched digital video) technology that has long been a mainstay of cable operations, Adara has made it possible for operators to pursue their highest priority goals without shouldering the costs, complexities and other drawbacks of traditional SDV.

Or, as CableLabs CTO Ralph Brown put it recently, Adara has “reinvented SDV.”

In a nutshell, SIPV exploits the dynamic power of video switching technology to minimize the amount of bandwidth needed for delivering linear cable channels, freeing up massive amounts of bandwidth for DOCSIS. At the same time, SIPV makes it possible for operators to continually expand their channel lineups no matter how many HD and UHD channels they might want to add over time without adding more video bandwidth.

All of this can be accomplished with SIPV at far lower costs with better results than node splitting, RF capacity expansion, pushing fiber deeper or introducing new compression technology with new set-top boxes, which explains why ever more operators are turning to SIPV as their priority recourse. In so doing, they also are ensuring they will get better results from the other methods, if and when they ever need to be implemented.

The availability of the SIPV platform comes at a crucial moment for cable operators. While they are in a powerful position as proprietors of the best broadband access network infrastructures in North America, they are hard pressed to keep up with demand for ever more broadband bandwidth when it comes to funding and executing evolution of the physical HFC plant. As a software-based mechanism for controlling use of existing network capacity, SIPV provides MSOs the tools they need to compete cost effectively in Internet time.

Thus, for example, an MSO with a limited amount of bandwidth available for DOCSIS owing to the volume of bandwidth used to deliver analog and digital TV services, doesn’t have to invest in plant expansion or analog reclamation to make room for DOCSIS 3.1 if it deploys SIPV. Hundreds of MHz of RF spectrum can be immediately freed for DOCSIS 3.1 by using the advanced switching mechanisms Adara has developed to accommodate delivery of all the operator’s digital TV content, thereby reducing the number of QAM channels used for TV to a fraction of current levels.

In the discussion that follows we first will look at some of the key market indicators that are shaping network evolution strategies in an environment that has already driven broadband bandwidth consumption far beyond anyone’s expectations. Looking at these indicators, it’s clear there’s no end in sight.

We’ll then explain in detail how SIPV provides the optimal framework for addressing immediate and ongoing transport capacity requirements arising from these trends. As shall be seen, no matter what stage of plant evolution an operator might be in, by making implementation of SIPV the next step in bandwidth expansion they will be better positioned than ever for whatever the future holds.
