What is media broadcast?

Media broadcast is traditionally the mass communication of programming from a single source to a TV or radio. The transmission or media transport of audio video signals is conducted over the air by satellite or optically by cable.

Background

The transition from analogue to digital media broadcast began in the mid-1990s and was prefaced by a shift within the broadcast production facility from analogue component video to Serial Digital Interface (SDI). The aim was to accommodate improved viewing qualities such as High Definition and to cut down on the cost of cabling. The fundamental processes of programme production and distribution did not change.

Similar forces are now at work across the media broadcast industry as satellite and cable is joined by internet protocol (IP) as a form of media transport. Internet distribution, which is also known as over the top (OTT), is on course to be the dominant form of media broadcast worldwide. At the same time, IP is replacing SDI within the facility and for the contribution of media to the production hub.

The need for greater agility to support ultra-high resolution video, better connectivity of infrastructure, and growing OTT demand is driving this evolution at pace. For the first time, the production and the distribution of broadcast programming will rely on the same underlying (IP-based) technology.

IP Transforms media transport

IP transforms media transport by converting signals into packets of data and routing them over the network. It replaces the point-to-point unidirectional link of SDI with the ability to send media as streams of video, audio, and metadata to anywhere with sufficient bandwidth and an IP endpoint.

Any format and any combination of audio, video, and metadata can flow bidirectionally across a facility or between facilities and over long distances using the same protocols, the same switchers, the same common IT architectures.

Media transport over IP liberates the broadcast industry from reliance on expensive, inflexible, outmoded, and proprietary hardware solutions at every part of the chain. IP software and solutions allows for more dynamic production video workflows as well as lower total cost of ownership.

Rather than pushing work linearly from source to consumption, broadcasters can build systems to perform one function one day and a different or multiple functions the next. Systems can be scaled up, or down; best-of-breed tools and services can be interchanged; production can be distributed with talent operating from anywhere.

Designing media transport solutions

For all the benefits of IP for production and distribution, the industry faces technical and cultural challenges in migrating legacy systems and existing practices. Transporting media over the open network is prone to congestion, packet loss, and piracy. Each media transport solution used to reroute or transform media adds latency. The internet adds uncertainty to the timing and synchronization of signals where previously there was none.

Net Insight pioneered broadcast-grade media transport over IP and robust media architectures at scale. We provide the speed, agility, openness, and security needed to address dynamic media consumption over IP with the extremely low latency and extreme quality needed for live production.

CASE STUDY

Nimbra platform was used for EBU for the Eurovision fiber network transport

Background

The European Broadcasting Union (EBU) which has members in 56 countries around the world is one of the largest alliances in the world in terms of public service media. It also operates EUROVISION, which is with its top-quality TV and a wide array of content one of the most premium distributers in the world.

The challenge

In 2004, while fiber capacity was becoming more widely used, the EBU took on the challenge of complementing its satellite network with a terrestrial variant, to keep up with the ever-changing industry. The goal was to find the perfect combination for seamless transmission of live broadcast video over a new, secure, high-performance terrestrial network, together with EUROVISION’s existing worldwide satellite network.

The solution

Choosing the perfect fit of platforms and solutions for the client made the solution which is utilizing Nimbra platform which is fully adapted both to the use of HD, JPEG2000 and to the transition to IP now taking place in the media industry.

The result

Regardless if it’s HD transmissions from the FIFA World Cup™ in South Africa or centralized productions abroad using the JPEG-2000 compressed feeds from the London Olympic Games, EUROVISION’s network is always being the forefront within the media industry.

Since 2004, when the EBU selected Net Insight’s Nimbra platform, the EUROVISION Fibre Network (FiNE) has evolved with Net Insight’s latest products and features.

The EUROVISION satellite and fibre network is one of the largest and most rock solid in the world. It delivers more than 80,000 hours of programming every year, the majority of which is live sports. Its undisputed reputation for flexibility and reliability is reflected in the prestigious events it regularly carries on the EUROVISION network.

“We continue our solid relationship with Net Insight for the development of our network since we aim to be the standardbearer for QoS and reliability around the world.”
