Story Highlights

A year ago, the broadcast-sports business watched as wireless and IP-based intercoms - the former moving to new parts of the post-FCC-auction RF spectrum, the latter leveraging audio's migration to networked infrastructure - continued to make steady inroads into a production infrastructure that increasingly implemented REMI and at-home techniques. A year later, thanks to COVID, being literally at home to run a remote production has gone from novelty to norm, pulling intercoms with it.

Riedel Communications' Rick Seegull sees IP at the heart of the intercom future.

REMI got REMI-ed is how Rick Seegull, manager, system consulting, Riedel Communications, expresses it. IP-based and, more recently, app-based intercom solutions have moved from interim, temporary solutions to established elements in suddenly disrupted workflows at broadcast networks. Even as that has pulled back a bit since last year, as more people can be in the production center together now, he says, many of them are still working remotely, even from home. And that'll be the case for a while to come, so our remote offerings are based on keeping the workflow identical, whether in the control room or at home/remote.

Solutions To Meet REMI Needs Intercom-system developers are responding with a variety of solutions.

Riedel's existing Connect-IP AoIP interface is an example. The company's VCP-1312 allows use of a smartphone or tablet as a full intercom element in combination with any of Riedel's Artist digital-matrix intercom systems. The Virtual Control Panels provide the same signalization as regular Artist control panels: the 12 keys available on two layers can be configured like any other panel key via Artist Director control and configuration software.

The VCP is available for iOS and Android mobile platforms, a route that has become well-traveled for intercoms in general since the onset of the pandemic. That does have intrinsic limitations, though not necessarily of the technical sort.

A [smart]phone will always be a phone first and an app second, Seegull explains. If a call comes in while it's being used as an app, it can disrupt a production, at least as a distraction or even interfere with it by changing the screen.

To avoid that, Riedel is promoting its recently introduced RSP-1216HL SmartPanel, an all-new 1RU model in the company's 1200 Series of intelligent intercom and control panels for real-time video, audio, data, and communications networks. RSP-1216HL is a compact version of the app-based RSP-1232HL SmartPanel user interface, both of which can be configured for remote/at-home use either over VoIP or AES67/syntonous mode, depending on available bandwidth. And a new frame - the Artist 1024, with up to 1,024 ports in a 2RU space - was added to Riedel's Artist ecosystem to address IP workflows and high port density.

IP is at the heart of both solutions, and it's the path to intercom's future, Seegull says, citing advances in IP workflows around SMPTE 2110-30 and -31.

The pandemic has revealed a deeper need for wireless communications between production personnel, whether working from home or onsite, according to Gary Rosen, VP, global sales, Pliant Technologies, which markets the CoachCom and MicroCom series of wireless intercom systems.

There were fewer productions earlier in the year and more people working remotely with less onsite technical staff, which increased the need for reliable, high-quality, easy-to-use intercom, he says, adding that it also increased the need for communications in general. Before, you might have been able to [talk directly] to a nearby colleague; now, suddenly, you had to stay distanced, even in the same room.

The pandemic may have accelerated the need for intercoms, but Moore's Law has remained inexorably in effect, as it had for decades before. For instance, the XR and M versions of Pliant's 900-MHz MicroCom, a full-duplex wireless intercom system, can accommodate from five to 10 users at between $400 and $800 per user and are aimed at the burgeoning secondary-professional, college, and high school sports-production markets, says Rosen.

The same cost dynamic has helped effectuate Pliant's newest product, the CB2, a scaled-down version of its flagship CrewCom platform: it offers many of the same features for up to 12 users but at a lower price point for midrange applications.

CB2 was part of our product plan from the inception of CrewCom, says Rosen. With the CB2, we're now able to offer a scaled-down version of CrewCom at a more affordable price. That puts it in reach of more budget-conscious users that need the quality of CrewCom but have more modest needs.

He notes that Pliant isn't looking at smartphone connectivity for intercoms. That comes with significant restrictions, such as added latency and degraded RF performance in loud environments, he says, adding that there is a dearth of demand for that type of solution among his customers, who have also shared concern about the use of personal-device endpoints for intercoms.

Our customers like the fact that we have a closed-end, managed system, he says.

He sees more flexibility for wireless in the 2.4 GHz and 900 MHz ranges, combined with CrewCom's conference-type networking system, which he contends provides more flexibility than conventional matrixes or partylines but offers connectivity to both.

The 2.4 GHz [range] can be engineered to be very robust [in] most environments, he says. Unlike analog RF, you can actually share spectrum [reliably] even with a good amount of other wire
