The Science of IP: An IT Architecture for Video Operations

In discussions about an Ethernet-based architecture, the concept of “fabric” often comes up. In many ways, fabric is a perfect analogy for how all the connections in an Ethernet design are woven together, just as tiny threads of cotton fiber are woven to create textiles. In the end, fabric can take many different shapes, but its underlying structure is consistent and, if woven correctly, builds a very strong composite. Ethernet fabric, in fact, is the very composition of similar and dissimilar data flows that define a set of functions in and around themselves. In our earlier paper, IT Essentials, we covered the basics of IP, addressing subnets, gateways, and other elementary concepts. This paper will focus more on the overall audio and video architecture as it applies to uncompressed video streams and how they function in an Ethernet fabric. That’s a lot to cover, so let’s get started.

The Pillars of the New SMPTE 2110 Standard

The broadcast industry is quickly moving toward the adoption of IP-based operations, and it is becoming apparent that the move to IP will be based on the proposed SMPTE 2110 standard, now in final draft stage. Much work has been done on the standard in the last year and many contributions made by multiple industry organization, including AIMS, VSF, and AES to name a few, to develop the standard and test it’s practical implementation. But what is SMPTE 2110 and how did we get here? This white paper is the primer you need for a basic understanding.

The IP Baseband Migration: A Hybrid Approach for SDI Facilities

In this white paper, we present an overview of the IP standards landscape and offer some practical guidance for operators, system designers, and manufacturers, with a focus on constructing IP “islands” within current SDI infrastructures. Taking into account key parameters such as control systems, SDI-to-IP conversion, and 12G SDI, this “island” approach offers a practical means of providing a low-risk transition to the world of uncompressed IP video, audio, data, and timing.

Practical Transition Strategies of SDI Facilities Utilizing Newer IP Baseband A/V signals

Practical Transition Strategies of SDI Facilities Utilizing Newer IP Baseband A/V signals

Abstract. Operators who have significant investments in large-scale SDI plant are going to face technical and budgetary challenges as they transition to newer IP-based topologies while still maintaining current SDI workflows. This paper has been written to provide some practical guidance for operators, system designers and manufacturers, with a focus on constructing ‘islands’ within current infrastructures. Given that SDI is the predominant topology, the center of these plants lies within SDI routing cores. Therefore, any transition will have to address key SDI architectures and augment an existing plant. The paper addresses a number of key parameters such as control systems, SDI-to-IP conversion, and 12G SDI. The conclusion of the paper points to an ‘island’ approach as a practical means of providing a low-risk transition to the world of uncompressed IP video, audio, data and timing.
