REMI has changed dramatically since pre-pandemic days. Martin Dyster takes a look at what has changed and how the evolution inspired a new Virtual Intercom Platform.Read More
AV Market specialist show InfoComm 2018 marked the first time that the Telos Alliance has had a dedicated booth. In previous years the company was represented via the Media Networking Alliance as part of the AES67 interop, but the launch of Telos Infinity IP Intercom, a product with huge Pro AV market crossover potential, was the catalyst for choosing our own space. Myself and Hal Buttermore attended the show, with a dedicated Telos Infinity demo system in a 10x10 booth on the edge of the Audio exhibit in Central Hall at the Las Vegas Convention Center.Read More
When talking about Audio-over-IP it is important to stress that we are not discussing something new. In fact, Audio over IP has been a part of the radio broadcast landscape for well over a decade. It was pioneered by the team at US-based Telos, led by the late Steve Church. Called “Livewire,” this AoIP protocol debuted at NAB in 2003. Since the introduction of that first low-latency, contribution-quality format, many other protocols have followed. However, the sheer amount of choice and conflicting marketing messages associated with each new protocol can be extremely confusing to potential adopters. The true benefits of an IP-based audio system are easily compromised by an inability to choose ‘best-of-breed’ equipment simply because ‘device A’ doesn’t support the protocol adopted by ’device B.’Read More
There is a misconception in the broadcast space that media outlets must wait for video over IP to mature before fully embracing an audio over IP (AoIP) infrastructure, but this is not the case. AoIP technologies have been stable for some time and today can provide the flexibility, reliability, and connectivity needed to deploy audio separately from video. Before the introduction of SDI video with embedded audio, video and audio had been handled separately for years. Although embedded audio seemed like a step forward, it did not reduce lip sync issues, and associated metadata is still easily separated from the audio. Since metadata is an increasingly essential part of new audio services, this becomes a major problem.Read More
The global television broadcast community is poised at the brink of the next great revolution in technological advancement – audio and video over IP. The great leaps that we’ve witnessed over the last 50 years, from black and white to color, mono to stereo, analogue to digital, 4:3 to 16:9, SD to HD and from stereo to 5.1, have benefitted the viewer at home each step of the way, and has been embraced with the purchase of the latest TV or Home Cinema system. However, in the backrooms of TV stations, broadcast engineers around the world have toiled over system designs, white papers and equipment catalogues while manufacturers have raced to bring out the next best widget designed to do the job.Read More
In the past, audio processing and monitoring required the purchasing of multiple, specialized hardware to support each function in the air chain. But now, thanks to the increase in the speed of Ethernet connectivity, and IT-based processing power, many of these same processes can be condensed and supported over IP. Audio in particular is making a move to the IP realm with the recent AES67 standard bringing interoperability between manufacturers. Even with this standardization, Audio over IP (AoIP) is still not being used to its maximum potential in the broadcast space.Read More
Even as AES67 levels the playing field in the broadcast space for Audio over IP (AoIP), there is still reluctance within the television industry to fully embrace it. We should take a cue from our brothers and sisters in radio who have adopted AoIP with open arms. Many in television think that as soon as you start talking about IP technology, it infers video over IP, and cannot see the benefits of AoIP. While video over IP still has a way to go before it reaches acceptance, that doesn’t mean that we need to wait to deploy AoIP. For decades, audio systems in broadcast facilities have been cumbersome and often over-engineered, but, that can change. Audio over IP has been tried and tested in the radio sector — these same solutions can be adapted for television.Read More
