As broadcast systems become more IP-centric, engineers and technicians rely more on software for troubleshooting. Consultant Tony Orme provides an introduction to the software too, Wireshark and how to use it.

In a second article you may have missed, The Broadcast Bridge writer, John Willkie offers advice in the replacement of SDI routing switchers. It may not be necessary to fork-lift your current router just gain some advantages offered by IP centric technology.

Wireshark is a free open source packet analyser running on Linux, UNIX type systems and Windows. Originally called Ethereal and first released in 1998, the name was changed to Wireshark as Ethereal was already a registered trademark.

Wireshark allows engineers to see what is going on under the hood of a network by monitoring an Ethernet port in promiscuous mode and then decoding and displaying the packets. With the intuitive graphical interface, it’s very easy to drill down into an IP packet, and then Ethernet frame to see the actual data.

Learn more about using this network troubleshooting tool in the article, “Understanding IP Networks – Wireshark.”

As the mission of television stations evolve, the underlying technology of routing video, audio, data, sync, time of day, tally and metadata through broadcast plants must also evolve. But do the changes mean you need an all IP infrastructure? Maybe not.

Many vendors of Commercial Off-The-Shelf (COTS) IP network switches suggest the video routing switcher (also known as a router) is as obsolete as a monochrome camera. However, the basic system designs from current vendors reveal that switching in their systems is managed by a completely new device called an Orchestrator.

Learn more about orchestrators and how they manage switching media in IP networks in the article, “Re-Imagining Routing Switchers,” from The Broadcast Bridge writer and consultant, John Willkie.
