Practical Transition Strategies of SDI Facilities Utilizing Newer IP Baseband A/V Signals
Scott Barella · 2016
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.
