VR Comes to Broadcasting

Virtual Reality, or VR, was one of the hot topics at the recent CES and NAB shows in Las Vegas. The technology began to develop in the early ‘90s, when everyone was sporting those funny goggles. The novelty quickly wore off, and VR fell off the radar. Development continued however, and 2016 may be the year it finally reaches critical mass. No one is certain what the most popular applications for this new medium will be, but broadcasters are carving out a piece of the VR pie for themselves.

All About Adaptive Audio Streaming

Streaming for broadcast is a hot topic right now. Consumer convenience prompted online video services such as YouTube and Netflix to offer Adaptive Multirate Video Streaming, and audio-only streaming providers—especially radio stations—are just recently able to offer the same convenience to their online listeners. Adaptive streaming is actually simple and inexpensive to implement, but it is a bit different from traditional online streaming. Here, we do a Q&A with Telos Alliance Director of Streaming Ioan Rus to help define the tech behind Adaptive Streaming and illustrate how both broadcasters and listeners come out ahead with Adaptive.

Vintage Audio: Wollensak 1500 Series Tape Recorders

Anyone who worked for the high school AV club or college media services department in the late ‘60s or 1970s remembers the Wollensak 1500 series reel-to-reel recorders. Along with the RCA hand-threaded 16 mm projectors, they were the bread and butter of instructional media. The hallmark of these devices was their ease of use and indestructible design. Get ready for a flashback to your adolescence, when all you needed to know about tape recorders was 'PLAY-RECORD-STOP', as we peer beneath that white and chrome exterior of Wollensak 1500 tape recorders.

TWiRT 303 - Hey, We Found Chris Tarr!

What’s an engineer to do when the old transmitter you’re getting rid of won’t fit through the building door?  You could cut it apart with a Sawz-All, or you could break out a wall and make a bigger door.  Well, Chris Tarr used both strategies during two recent transmitter upgrades.  The Ninjaneer joins Chris Tobin and me for a TWiRT reunion episode.
