IP is delivering unprecedented flexibility and scalability for broadcasters. But there is a price to pay for these benefits, namely, the complexity of the system increases significantly as we add more video and audio over IP.
One of the earliest and most widespread applications of synchronizing was in television.
With mature, cloud-based services now prevalent across the industry, helping to process and distribute content faster and more accurately than ever before, the long sought-after promise of producing content in the cloud—reducing cost and physical barriers—prompted broadcasters and production companies to experiment with new ways to make it a common reality.
Synchronizing became extremely important with the growth of AC power systems, which ended up being used to synchronize all sorts of equipment, from Radar to television.
In this second instalment of our extended article looking into the practical applications of SDI and IP we look at how SDI is naturally plug-and-play and works with well-defined formats whereas IP is dynamic and more versatile but requires greater thought in making it work reliably.
Over the past year, as broadcasters and production companies have expended great effort to reconfigure their workflows and develop new ways of working amid strict safety protocols, so too have the manufacturers of the technology and systems they rely on.
SDI has been and continues to be a mature and stable standard for the distribution of video, audio and metadata in broadcast facilities. From its inception in 1989 to the modern quad-link 12G-SDI available today, it has stood the test of time and even with the advent of IP and Ethernet, it shows no sign of waning.
