Serial Digital Interface (SDI) has, until recently, been the preferred transport mechanism for broadcast transmission. Its main advantage is that it provides a consistent and predictable delivery of data which is ideal for audio/video transport. However, networks in the broadcast industry are now in a state of flux. Increasingly there is a shift away from single-purpose legacy systems like SDI, and a shift towards multi-purpose IP-based networks.
This 2 day course will build your understanding of the fundamentals of networking, in which data is transported as packets switched and routed around a common infrastructure. You will learn the key network protocols used and the network layers that are commonly used to understand their scope and function in routing packets between IT hosts and from network to network. The emphasis will be on Ethernet (layer 2) and Internet Protocol (layer 3). You will learn the essentials of enterprise networks and the ways that a network infrastructure can used for media applications.
Delegates will build practical networks hands-on to deliver unicast video streams across routed and switched networks. The resilience of the network to deliver video streams at layer 2 (spanning tree / rapid spanning tree) will be compared and contrasted practically with the failover of routing protocols at layer 3 (OSPF routing protocol). Layer 3 switches will be used for interconnecting networks and typical commands required for these exercises will be covered on the course.
James Stellpflug – VP Product Marketing, EVS Remote production is one of the most significant benefits of IP infrastructure but along with it comes one of the biggest challenges of an IP-based live media workflow. James speaks about the importance of implementing sophisticated routing and control systems for IP flows to ensure that IP feeds aren’t affected by any latency and can be controlled and delivered for playout – as securely and with the highest quality as point-to-point/SDI networks.

Patrick Daly – Director of Engineering, Atlanta M&E, Diversified Patrick has worked on several IP projects and will cover: baseband vs IP infrastructure; developing an IP media fabric core with legacy hybrid SDI constraints; system documentation for IP media fabric installations; and factors in selecting optics: price, simplicity of design, ease of maintenance, network topology, physical/geographic footprint.

Gary Olson – MD, GHO Group LLC Line drawings and wire lists are no longer sufficient to build and maintain a media production and broadcast facility. IP mapping, VLAN’s, API’s and communications between systems, network topology and workflows are key. This presentation covers the types of documentation that are critical for IP centric broadcast facilities. [maxbutton id="129" ]
Antony David – CEO, Solid State Logic Antony explains the benefits of AOIP networks and why those implemented today will mesh with the evolving SMPTE ST 2110 and NMOS IS-04 standards. An example of a fully networked multi-room production facility at a major European broadcaster will illustrate these points and the capabilities. [maxbutton id="134" ] [maxbutton id="135" ]
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.

When the national broadcaster TV 2 recently relocated both of its locations, an all IP infrastructure for live production was chosen. Ole Johan Skogheim (Head of Systems, TV 2 Norway) describes how the main goal was to reduce impact of distance and to merge production islands’ connecting all resources in a network based infrastructure. Initially based on SMPTE ST 2022-6/-7+AES67, but planned for SMPTE ST 2110 upgrade, the project resulted in a true multi-vendor environment giving TV 2 greater freedom in the allocation of resources and location of operations.

In parallel with the development of SMPTE ST 2110, AMWA has been developing registration, discovery, and connection management tools needed to build IP-based workflow systems more rapidly. This talk by John Mailhot (CTO, Networking & Infrastructure, Imagine Communications) covers the IS-04/05 specifications and how they integrate into routing control environments.
