Lessons Learned Part 2: Optimal Handling of PTP
The first blog in this “lessons learned” series took a close look at how important it is to use a PTP-aware switch when implementing IP-based media workflows. In this second installment, we’ll focus more on IEEE 1588 Precision Time Protocol (PTP) itself and how to handle PTP configuration and data correctly.
The IP Migration: Working With Audio Studios
When you hear about the audio industry’s migration to IP, the “classic” implementation that comes to mind is that of either a greenfield application or a complete equipment replacement. Either response is valid, given that many of the initial implementations highlighted were just these kinds of projects: entirely new builds undertaken by high-profile media organizations.
Fiber Is Here to Stay
Fiber optic media-over-wavelength transport has been a staple of live television production for decades now, but any application with high bandwidth and/or high bit rate requirements can benefit from fiber.
Lessons Learned Part 1: Getting IP Right With a PTP-Aware Switch
At a recent meeting of Artel engineers, we decided to collect some “lessons learned” stories. We figured we’d share these stories — focused around IP-based media workflows — in case they can help you to prevent unwanted downtime or avoid a painful failure.
Dave Rowell and Filo Classical
In the 15 years since he founded FiLO Classical, recording engineer Dave Rowell has consistently garnered praise — and no small number of awards — for his artistic and technical skill in location recording and broadcasting classical music.
Read how Rowell adopted a RAVENNA-based real-time AoIP solution including two Artel Quarra PTP- aware ethernet switches to keep everything perfectly synced.
Configuring Your IP Switch: The Why Behind the How
Artel's documentation page has dozens of PDF files explaining how best to configure your equipment for your operations. Page through any guide, and you’ll learn exactly what to do to get you up and running. Simple and helpful screenshots allow you to get through setup quickly and successfully without necessarily understanding every switch feature so you’re pretty much good to go. But maybe you’re interested in the “why” as well as the “how”? This blog takes a closer look at three key features — IGMP snooping, QoS, and IEEE 1588 PTP — and why they are important in supporting a stable AES67 network.
Doing the Job (Every Job!) and Doing It Right
From the moment Artel receives a PO or a request for delivery, the company’s operations team is hard at work doing all it takes to get the job done and do it right. Responsible for assembly, testing, packaging, and shipping, operations drives delivery of the products essential to customer success.
Preserving PTP in Remote Production Environments
The industry has been talking about remote production for a while, and for good reason. The conventional live production model, in which you send a team and equipment to the venue, can be costly in terms of both time and money. Travel is expensive not only because you need to pay for transportation and lodging, but also because the human and technical resources are tied up all that time and unavailable for any other production. As a result, you’re limited in the frequency and number of events you can produce.
Case Study: Cablenet
Cablenet operates a next-gen hybrid fiber-coaxial network that supports broadband and HDTV services. In a project designed to augment this network, Cablenet sought to link to stadiums across Cyprus to two remote production sites to bring content to the network hub and on to the headend. They wanted to introduce Media over IP into the network, position themselves to use SMPTE ST2022-7 redundancy as an option in the future, and avoid the cost of Satellite links in spans where Wave Division Multiplexing didn’t meet the loss budget.
Quarra Fits the Bill for Calrec
As a leading designer and supplier of audio broadcast mixing equipment, Calrec offers solutions that help radio broadcasters to engage audiences in innovative ways. The rising popularity of streaming services has increased competition and made interactive engagement with listeners an increasingly important capability for these broadcasters.
