Multi-Systems/Cable Operators: Reclaim Bandwidth and Speed Up Your Migration from QAM to IP Video

There is significant consensus that an all-IP infrastructure is the vision that cable operators need to implement to remain competitive.  But, while there is consensus on an all-IP future, the path to getting there is just not perfect.

In fact, the transitional path (i.e., initiatives) that operators are considering as they migrate to IP is rooted on over-spending on future stranded assets like switched digital video (SDV), digital terminal adapters (DTA), expensive gateways and consumer premise equipment (CPE), video compression tools, etc.  

Instead, cable operators must consider a more effective IPTV migration path - that leverages all existing investments - to solve each initiative, over time. 

Initiative #1

Reduce Video Costs


To remain competitive, cable operators need to reduce video costs while increasing high-margin service offerings, such as high-speed data (HSD) services. For that to happen, cable operators need to modify their quadrature amplitude modulation (QAM) plan to add the latest version of data over cable service interface specification (DOCSIS), implement QAM cards and cable modem termination system (CMTS).

As a first step, cable operators are transitioning to the IP home using multi-room set-top box (STB) and whole home gateways to centralize tuners, cableCARDS and DVRs. While this first-step to the IP home can reduce CPE costs by up to 30%, there is more to be had.   

Azuki can help you achieve a CPE cost reduction of 50% to 80% without gateways, tuners, cableCARDS or DVR storage at home. Even more, what if you could achieve a CPE cost of $250?



Initiative #2

Increase VOD Capacity


Cable operators are trying to increase VOD capacity by compressing VOD to fit more sessions inside video QAM channel.  While this approach works, it requires upgrades to MPEG-2 encoders to support high channel density.  In other words, to compress VOD to fit more sessions inside video QAM channel requires significant hardware power to support high channel density, which translates into expensive upgrades. 

What if your QAM IP bandwidth could be shared to flexibly deliver the VOD requested, without denial, or stranded dedicated VOD bandwidth?



Initiative #3

Increase HD Programming


As demand for more HD programming grows, cable operators need more bandwidth to meet these requirements.  Switched digital video (SDV) and digital terminal adaptors (DTA) approaches are being used to expand video bandwidth. 

SDVs allow operators to provide subscribers with access to highly focused content channels without the need to commit dedicated bandwidth to each channel.  Channels can be switched on this network only when they are requested by one or more users. Though this SDV approach works, it requires expensive and time consuming head-end and STB upgrades.

Azuki can help you offer massive delivery of linear TV by edge-based adaptive bitrate (ABR) unicasting, distributed over-the-network ONLY when requested using standard IP/Web protocols. Azuki can also help you expand from 80 to over 500 HD channels with this approach.



Initiative #4

Reclaim Bandwidth


Cable operators are also leveraging (or considering the use of) DTAs to expand video bandwidth to play digital QAM video on analog-only TVs.  While this is a much less dramatic approach to providing more bandwidth in comparison with SDVs, it still requires increasing CPE costs when taking analog off the line-up.

What if you could get IP-STBs to deliver a better service than DTAs over your IP QAM connections?



Initiative #5

Deliver Multi-Screen TV


The transition to IP and multi-screen video services requires a significant number of enhancements to existing video infrastructure and back-office to support the ability to specify content restriction based on complex licensing agreements, including location, network, device, Class of Service, user, etc.  

Also, it requires the ability to manage and enforce upsell/cross-sell, special offers, promotions, rental, purchase, including the ability to offer free, ad-supported and premium content.  It also requires the ability to support and manage multiple consumer-electronics (CE) and mobile devices.

Azuki can help you have IPTV ABR natively supported on multi-screen devices  to deliver unified TV experiences across iOS, Android, PC/MAC and Xbox devices, without complex in-home multi-screen conversions or gateways.
