Tom’s Tech Blog – NAB 2016 is a wrap

It was great getting out to NAB (my 29th consecutive!) and talking about everything we’ve been working on all year. The VH2 Hybrid garnered a lot of attention, as well as the new 4.0 CrossLock firmware for ACCESS/BRIC-Link. But what was that shiny black object? Could it be a preview of things to come? It […]

Tom’s Tech Blog – Verizon XLTE is terrible…except when it’s awesome

If you’re a LiveShot/ACCESS Verizon LTE user in the US, your wireless modems will likely have a choice between the “standard” LTE band 13 (700MHz) and the “XLTE” Band 4 (AWS-1700/2100MHz). When I say your modems will have a choice, I mean it literally, since you can’t easily choose in software.

Tom’s Tech Blog – A secret about Comrex Connect International Modems

I’ve griped plenty in the past about the wireless situation in the USA, where each carrier uses completely different LTE bands, so no universal USB modems exist. But here’s a secret: The Comrex Connect modem designed for International use includes virtually every LTE band in use in the USA.

Tom’s Tech Blog – Here comes the VH2

Debuting at NAB this month is the VH2, an audio telephone “hybrid” for VoIP. Hybrid is in quotes because it’s not doing the traditional phone line cancellation (not required in the VoIP world), but functionally it acts like a traditional studio telephone interface.

Tom’s Tech Blog – Thoughts On Security

Several stations using Barix codecs for STL have been diverted to receive an adult-oriented stream, then locked to that stream this week. Many theories are floating about the sophistication of the attack, but I’m a fan of Occam’s Razor on this. I’ve seen enough web interfaces unprotected out there that I think this attack employed a simple lookup on an Internet-of-Things directory site, then login via default password.

Comrex Connect LTE Modems

USB modems are by far the simplest way to do audio and video remotes over LTE. But they are becoming less available, and their form factor generally isn’t “pro-grade”. So we’re introducing our solution, the Comrex Connect Modem. There are actually three versions, thanks to all the intricacies (both technical and political) of interworking with […]

4G LTE in the United States

Spectrum allocation for 4G wireless services in the US is a mess. Here’s a short list of the four major wireless providers and the spectrum on which they serve LTE: Verizon: Their main network is in the 700MHz band (band 13) but for a couple of years they’ve been offering LTE in some areas on […]

Venting on the XLR

I love XLRs. I hate XLRs. They are universal, robust, and easy to repair. They have obvious gender to indicate direction. They are the only respectable way to provide a pro-grade, balanced audio I/O. They also carry digital audio. They are also huge. In an age where portable gear is shrinking, it’s crazy to dedicate […]
