Media Broadcast

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.

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 extreme low latency and extreme quality needed for live production.

We have the solutions and the expertise to help you design, build and navigate optimal media transport workflows which seamlessly blend best in class protocols and vendor integrations.

Everything we do is driven by your requirements. No costly hardware. No hidden infrastructure additions. Open, all IP and all yours.
