The adoption of IP technology across the whole broadcast workflow is now well underway. IP has already been used for many years for the purposes of broadcast contribution over wide area networks (WANs). The technology is now also beginning to be used in local area network (LAN) environments for transporting broadcast signals within studio- and campus facilities. In many cases though, broadcasters are initially considering a like-for-like network replacement of baseband with IP, which, for the time being, still implies higher initial cost, not least because of the need to convert the SDI output of existing equipment to IP (until all broadcast equipment becomes IP capable). There is much more to IP than simply mimicking existing baseband networks though. The seminal VRT/EBU LiveIP project (the first practical demonstration of using a multi-vendor all IP environment for live production, back in 2015-2016) made the point very eloquently: IP enables workflows to be “remote, shared and automated”. IP brings the opportunity to harmonize local and long-distance media networks around a single technology – so-called IP LAN/WAN (local and wide area network) convergence. This means that it becomes much easier to share equipment, studios and control rooms, and even production staff, across locations...
For reliable IP media operation, bandwidth needs to be reserved for flows and the network needs to be protected from unauthenticated senders and receivers. AMWA NMOS IS-06 Network Control is a publicly available multi-vendor interface specification between a broadcast controller and one or more network controllers. Find out from Thomas Edwards (VP Engineering & Development, Fox) and Subha Dhesikan (Principal Engineer, Cisco) how it allows the broadcast controller to learn about network topology, to authorize endpoints, and to allow networked media flows to move with reserved bandwidth, and it is supported by multiple network equipment companies to avoid vendor lock-in.

From content production to distribution, Nevion solutions are used to power major sporting and live events across the globe. Some of the world’s largest media groups and telecom service providers use Nevion technology, including AT&T, NBC Universal, NASA, BBC, CCTV, EBU, BT and Telefonica.
MuxLab’s new 3G-SDI/ST2110 over IP Uncompressed Extender (model 500767) provides two methods of signal extension: one riding on an IP-infrastructure running 4K AV through a 10GB Ethernet switch; and another allowing a more traditional point-to-point extension using CAT5/6 or fiber cable. In both scenarios, uncompressed resolutions up to 4K/30 are supported.
At the 2018 NAB Show in April, GatesAir introduced Intraplex IPConnect, a standalone hardware device with integrated award-winning IPConnect software for reliable, secure data transport. Previously available only as an option for IP Link audio codecs, the new device provides reliability and security for virtually types of IP data, including those from IP audio codecs, HD Radio streams and Web or SNMP-based remote-control applications. The device can be used as an IP Gateway or a LAN bridge to provide point-to-point and point-to-multipoint connections.

When remote news crews go live from a breaking news scene or a major event, they want to be ahead of the competition at every step.
Reliability, flexibility and convenience are key transmission requirements when covering a story. When the location is on challenging terrain, or if the crowds are overloading the cellular networks, or in adverse weather conditions – or sometimes all three at once – reliable transmission paths are critical to ensuring that high quality video gets back to the station or direct to the viewer.
This paper looks at the evolving needs of pay-TV service providers as their growing multi-screen distribution strategies create increasing complexity in their content protection systems. It highlights the four key drivers that are causing pay-TV companies to reconsider their existing CAS/DRM architectures, and explains the reasons for moving toward a more unified approach that streamlines the implementation and operation of content security across multiple networks and devices.
Whenever we visit new prospects we see the same problems time and time again. Whether they be banks, broadcasters, post-production facilities or telecoms companies, they face similar technical challenges when ingesting, curating, protecting and sharing video assets.
