Low latency networks and non-blocking switches are terms now appearing in mainstream broadcasting. But what do they mean? Why are they relevant? And how do we make Video over IP work?
ST2110 has succeeded in abstracting away the video, audio, and metadata essence from the underlying transport stream. In doing so, we’ve had to build a new timing reference and implement the IEEE-1588:2008 protocol. Otherwise known as PTP (Precision Time Protocol), this packet switched protocol presents us with new and interesting challenges never experienced in broadcasting before.
The need to employ non-blocking Ethernet switches has come as a surprise to many broadcast engineers. X-Y matrix SDI switchers are at the heart of every broadcast operation and their non-blocking characteristics have been assumed and taken for granted. Simply replacing an SDI router with an Ethernet switch will not deliver the gains CEO’s are expecting.
To help readers understand the new emerging technology, The Broadcast Bridge Technology Editor, Tony Orme, has written this Essential Guide, Video Over IP – Making it Work. You will learn about video over IP at a deep engineering level to help you understand the key components required to make a successful IP infrastructure deliver the COTS benefits CEO’s are demanding.
Readers will also learn about PTP and its application in layer-2 networks, how switches process PTP data, and the information needed to design an IP network. Jitter and latency are key considerations and this tutorial covers the common sources of packet jitter and their remedies.
Learn about the underlying principles of Video Over IP and how you can deliver the COTS efficiencies your CEO demands. Read the tutorial, Video Over IP – Making it Work.
