Phasing Into IP Broadcast? Don’t Get Locked Out

One issue that tech managers need to consider when making the transition to IP broadcast is vendor lock-in, according to Nestor Amaya, president of Coveloz. “Vendor lock-in can be a real challenge, and that’s partly because, even with SMPTE ST2110, it’s one thing to have a standard, it’s another thing to guarantee that different implementations of that same standard will be compatible,” he said. “But that’s just the transport; 2110 doesn’t at all touch on: how do I debug my network? And how do I control those boxes? Until we have standards for those things, it’s going to be really, really hard to buy equipment from different vendors. It requires the end customer to really work closely with their suppliers to make sure [their equipment] can work together.”

Tech managers must also weigh the differences between the current standards available, notes Mark Hilton, vice president of live production at Grass Valley. SMPTE ST2110 is one way to go, but there’s also SMPTE 2022-6. “2022-6 has some advantages in that it feels more like SDI because you’ve got audio and the metadata embedded with the signal, but it has some disadvantages as well—you lose some of the flexibility that maybe you’d like to have,” he said. He also points to TR-04, which he describes as a middle ground: “[It’s] 2022-6, but audio is separate it AES67. There’s a suite of options, and I think for customers it’s important to talk to people who have experience doing this to understand what you’re getting and to have a clear plan for how you want to migrate.”

Get the Lead Out

Context is important—it’s important to know what words mean and in what context they are being used. Having said that, there are systems or software applications that will talk to and control assets on a network via unique IP addresses for each device. I know this—I have seen this. What I am somewhat interested in is the missing link from large manufacturers in the AV industry.

Don’t Overlook TCO for Ed Tech

When shopping for projectors, savvy education technology managers know to ferret out the total cost of ownership (TCO) rather than fixating on the lowest price. That’s why vendors are increasingly offering projectors with hybrid designs, self-cleaning filters, and light sources that last 20,000 hours or longer. The time spent calculating genuine TCO can really pay off.

You Don't Need Stage Lighting, Do You?

You've got to love it when you reach a facility and you realize that they must have run out of money (or just used a very bad integrator) with no backup in place, because the stage has no lighting. Now I don't mean just a little bit of lighting, or a bit of cheesy lighting, or some scattered pro lighting that was done without a proper lighting plot. I'm talking about a stage with eight potlights (hi-hats if you prefer) at the front edge of the stage front.
