In 2016, there is going to be a shift in how live events are broadcast to audiences. According to Steve Jones, Head of Live and Production for Viocorp, the use of cloud-based infrastructures for the webcasts his company provides to enterprise and government customers is expanding quickly. In 2015, nearly 30% of Viocorp production events relied on the cloud. Jones predicts that this year, about 70% of the company’s events will run on the cloud.

Alex Zhang, Senior Product Manager for AWS, and Sabina Andersson, Associate Product Manager, Cloud Solutions for Elemental, both acknowledge this growth is on the immediate horizon. Although there will always be a place for on-premises infrastructure – both Zhang and Andersson see these as complementary deployments – cloud-based infrastructures for live broadcast now match the capabilities of on-premises hardware, are easy to use, and save time and money that data center maintenance requires.

Elemental’s cloud-based video solutions, powered by AWS, can manage a growing variety of content sources, and offer increasingly feature-rich customizable solutions that allow for monetizing opportunities through live-to-VOD services and ad insertion, while providing both the scalability and resiliency that customers depend on.

The AWS media ecosystem and Amazon CloudFront CDN support companies ranging from start-ups to enterprises as they globally scale media content delivery. The goal is to customize content for end users based on viewing device and geographic location, all with end-to-end content encryption so consumers have the best viewing experience with minimal latency.

Tune into an on-demand replay of the webcast, Broadcasting Live from the Cloud, to learn more about live broadcast workflows leveraging cloud-based infrastructures, what’s required for the successful delivery of live events, Viocorp’s decision to move to cloud-based infrastructures, and to see a demonstration of Elemental Cloud.

Hybrid broadband broadcast TV (HbbTV) offers a significant opportunity for broadcasters to enrich video services, generate additional revenues and build viewer loyalty through an improved user experience. HbbTV enables over-the-top (OTT) video streaming and can be used to support catch-up or restart TV services alongside traditional linear broadcast.

The aim of HbbTV is to align broadcast and broadband delivery of entertainment services for consumers through connected TVs, set-top boxes and multiscreen devices while enabling new and interactive services. In addition to catch-up and restart TV, HbbTV enables electronic program guides (EPGs), teletext, video-on-demand (VOD), social networking, gaming and second screen applications. HbbTV was originally intended to enrich digital terrestrial television (DTT); however, cable, IPTV and satellite networks are also incorporating HbbTV into their video service offerings.

Consumer demand and regulatory incentives are driving the expansion of HbbTV. Most European countries plus Turkey, Vietnam, Namibia, Australia and New Zealand have launched OTT services for DTT. Plans are currently underway in the United Kingdom, Italy, South Africa, Singapore, the United States, and some West African countries to introduce HbbTV as well. In other countries, it is a legal requirement for operators to carry HbbTV even when OTT VOD services compete with their own linear offerings.

In countries with HbbTV services, many DTT set-top boxes are HbbTV-compliant with built-in HTML browsing capabilities and support for MPEG-DASH streaming. In Germany, more than 60% of televisions sold are connected TVs, 92% of which are HbbTV compliant.

Broadcasters adopting HbbTV face a key challenge in architecting VOD and live-to-VOD services: ensuring that additional workflow elements needed for HbbTV effectively integrate with existing linear TV delivery infrastructure. To learn how software-defined video solutions from Elemental enable unified live linear and OTT workflows to support HbbTV, download the solution brief.

What would it be like to feel like you are at an event – courtside at a basketball game, front row seats at a Broadway play, behind the wheel at NASCAR, on the show floor at CES – from the comfort of your home? Nokia’s OZO, a professional grade virtual reality (VR) camera, has demonstrated its immersive technology with the support of Elemental software-defined video processing at two events, including the Finnish company’s November 30 product launch in Los Angeles.

The launch event, targeting the media and entertainment industry, featured a live broadcast in full 360 3D VR of the musical band Best Coast performing on the Capitol Records rooftop. Event attendees seven miles away at LA Live donned VR headsets to experience “front row seats” via live streaming. “It felt like you could reach out and touch the performers,” said Tom Gilman, Technical Marketing Manager at Elemental, who attended to support the Nokia-Elemental demonstration. “There was 360-degree 3D, with depth and immersive audio.” This, he explained, enables headset wearers to hear spatial audio much like one would while watching home theatre.

For the demonstration, the Nokia OZO filmed the Best Coast performance and created a single video to feed Elemental Live for encoding. The encoded stream was packaged in MPEG-DASH and sent to an Akamai CDN. The VR video was available to attendees on a Nokia app using VR headsets.

What made Elemental’s support of this event stand out, explained Gilman, was the flexibility of software-defined video solutions to allow for processing of video with unique requirements including cropping the video and using a custom aspect ratio. The audio also required special handling using built-in audio mixing functions to accommodate the OZO camera. Gilman said that these are standard features in Elemental Live and available via the GUI or REST interface. 

The Nokia OZO is a spherical camera that has eight sensors and eight microphones, and is the company’s first hardware release since selling its devices division to Microsoft in 2013. James Murphy, Elemental Sales Manager, recently attended a Nokia OZO demonstration at an NBA game in Los Angeles. The camera, which was positioned courtside, provided a “jaw-dropping immersive experience,” according to Murphy. At one point, he explained, a security guard leaned in to the OZO and Murphy instinctively felt the urge to step back.
