Resources & Expert Advice to Make the Trek to a Unified Headend Easier

"One of the biggest challenges for Pay TV operators today is how they retain and grow their subscriber base. If they get into the habit of introducing compelling new services, like 4K/UHD, before market rivals, that is going to give them a competitive advantage. And this ability to ‘get out of the gate first’ is enhanced by the move to software-defined video and then a unified headend."
John Moulding, Editor-in-Chief, Videonet

The TV industry is in the midst of dealing with multiple revolutions happening at once, and one with the greatest potential for positive impact is underpinned by software-defined video.

With benefits such as faster innovation and reduced costs, a unified video headend for traditional and multiscreen content delivery seems like a natural next step for video operators. We’ve lined up several resources to help you assess the technological and operational benefits and challenges a unified headend offers.

Watch the Webcast: Unified Headend: What You Need to Know to Take the Next Step in TV Operations Transformation

What’s inside: In this joint webcast by Videonet and AWS Elemental, we investigate the characteristics of the unified headend, the new service demands that can trigger deployment (including skinny OTT bundles), the barriers to implementation and how you overcome them, the migration path to a unified headend, and the technology developments that make it easier. Other topics our experts discuss:

  • The migration towards software-based video processing, the services and functions that have benefited from a software-based approach and the impact this is having on multiscreen and primary screen content delivery.
  • Why a unified headend is the natural next step for operators and broadcasters using software-based video, and the operational impact of unifying currently separate broadcast and multiscreen video workflows.
  • How a unified headend helps when launching new services like 4K/UHD, skinny bundle OTT offers, and other new video services.
  • Industry developments that could make the migration to a unified headend easier, and what you can do now to prepare the ground for a unified headend later.
  • How to implement a unified headend in a multi-vendor environment, technical challenges when merging different systems, and the implications for operations teams.

What’s inside: Examples explaining how software-based video encoding, multiplexing and system management can enable operators to extract additional capacity from their networks, increase the QoS and the reliability of linear TV delivery networks through full system redundancy, simplified workflows and advanced configuration options. Plus, the benefits of software-based video processing are highlighted through the mapping of migration plans to HEVC and 4K Ultra HD TV.

What’s inside: BT, one of the world’s leading communications companies with one of the most valuable sports portfolios on the planet, changed from a heterogeneous environment with a specific set of hardware-based compression systems for set-top box delivery, and a second set of specialized systems for multiscreen video delivery, to a unified infrastructure enabling BT to operate, manage and maintain video processing for BT TV Everywhere, the BT Sport App and the BT Sport Ultra HD Channel. By collapsing the company’s video architecture, BT increased cost savings and boosted operational efficiency, all while providing subscribers with a consistent viewing experience across platforms.

At NAB 2017, more than 660 individuals from the media, entertainment and technology industries laced up their shoes in the name of diversity and inclusion at the 4K 4Charity Fun Run. In support of this event, 4K 4Charity sponsors, partners and supporters raised more than $52,000 for nonprofit beneficiaries, Mercy Corps and Women Who Code. This funding will enable these deserving organizations to continue in their work to aid millions of people who are at risk or underrepresented around the world.

Breaking $50,000 in total donations marked one of many exciting “firsts” for the 4K 4Charity Fun Run Series. The run at the NAB Show also achieved milestones such as the first time to garner support from 17 corporate sponsors, the first time to offer a complimentary t-shirt to early registrants, and the first participant to finish the 4km (2.49-mile) course in under 13 minutes.

Our generous 4K 4Charity Fun Run sponsors helped make each first and every achievement possible. If you would like to sponsor the September 16 Fun Run at the IBC show, contact Kate Incerto at incertok@elemental.com.

Last week, we shared the news of NASA’s plan to deliver the first-ever live 4K video from space and discussed some of the challenges that NASA, Amazon Web Services (AWS) and AWS Elemental addressed in achieving this historic milestone. Today, at 10:30 a.m. Pacific Time (US), that milestone was surpassed today as part of “Reaching for the Stars: Connecting to the Future with NASA and Hollywood,” an NAB Show Super Session at the Las Vegas Convention Center (LVCC).

To bring the first live 4K signal from the International Space Station (ISS) to viewers here on Earth, we designed three primary workflows based on AWS Elemental software and AWS solutions. Aboard the ISS, a 4K camera and AWS Elemental Live encoder provided the HEVC 4K video stream and sent it in a UDP transport protocol via the ISS network into Johnson Space Center (JSC).

From JSC, the 4K video was decoded and routed along with a separate audio feed to an AWS Elemental Live system on-premises, which encoded and sent the signal via the NASA network to an uplink facility for delivery via satellite to a downlink truck on site at the LVCC, where the signal was brought into Room N249 for production and live viewing on 4K projectors.

Finally, to bring the live 4K event feed to the viewing public on multiscreen devices, AWS Elemental Live systems sited at LVCC furnished redundant encoded adaptive bitrate HLS streams to two separate AWS Elemental Delta cloud instances for origin services. These origins delivered IP HTTP Live Streaming (HLS) outputs through Elastic Load Balancers to the Amazon CloudFront content delivery network (CDN). Amazon Route 53 provided Domain Name Services, redundancy and routing policies to better manage the flow of traffic and failover to reach regional AWS Elemental Delta instances. Amazon Cloudfront and Amazon CloudFront Regional Edge Caches provide the global CDN for delivery to multiscreen and connected devices everywhere, with network monitoring performed by Amazon CloudWatch.
