One of the great advantages of the internet is that it relies on open standards that promote routing of IP packets between multiple networks. But this provides many challenges when considering security. The good news is that we have solutions through IPsec (IP Security) to alleviate these concerns.
Planning for any kind of live TV broadcasting starts with a ‘what-if?’ list. What if the power source fails? What if a key production person gets sick or hurt? What if broadband internet access becomes unstable? What are the chances for each ‘what-if?’ and what back-up alternatives fit the budget? The…
A technology might seem to be near maturity when design approaches that were once theoretical, and impractical to build, become easier to make and start to hit the market. LED lighting isn’t necessarily easy to build in 2021, which is why it’s still not as affordable as we’d…
The Advanced Television Systems Committee (ATSC) recently announced the release of a new Request for Proposals (RFP) for Broadcast Core Network technologies to enhance the ATSC 3.0 broadcast standard. The project is on a fast track, with initial responses due by December 31, 2021. Could Broadcast Core Networking be a new license for…
In some ways, the best DOP and a sadist have a lot in common: We strive to make our viewers suffer and the curious thing is, our audiences love us the more for it. Of course, DOPs, like most civilized people, wouldn’t think to wrench the fingernails from our v…
The power and flexibility of cloud computing is being felt by broadcasters throughout the world. Scaling delivers incredible resource and the levels of resilience available from international public cloud vendors is truly eye watering. It’s difficult to see how any broadcaster would run out of computing power or storage, e…
As Pro AV productions get more complex, the industry has longed for a set of common, ubiquitous, standards-based protocols for interoperability on a managed video-over-IP network. In 2017, as the first set of SMPTE ST 2110 standards were published, AV professionals saw the framework of their dream become reality.
Most live remote outside broadcasts are thoroughly planned by producers and directors who are often too busy to consider potential equipment problems. Technology is an engineering responsibility. Engineers must be ready for any circumstances that threaten to take the show off-script or off-air, from dead wireless mic batteries to unexpected…
The audio vectorscope is an excellent tool for assuring quality in stereo sound production, because it makes the virtual sound image visible in the same way that a television vectorscope allows the color signals to be seen.
Time base correction is an enabling technology that crops up everywhere; not just in broadcasting.
