Audio over IP convergence in Broadcast, Intercom and Commentary Systems 26/09/2017
Ivan Olmeda, Director of Corporate Strategy & Development of AEQ, talk about Audio over IP convergence in Broadcast, Intercom and Commentary Systems for "The IBC daily", the official newspapper of IBC.
AEQ is consolidating its development of audio, video and communications over IP for the broadcasting industry.
When AEQ acquired KROMA Telecom, a company dedicated to Intercom Systems, we ported all the IP audio technology for broadcast that AEQ already had implemented into these systems. It effectively meant renewing the complete KROMA product line; contributing with DSP technology to user panels and making Intercom systems provide true broadcast quality audio.
Now, therefore, the equipment infrastructure has mixed functionality, that is, audio mixing consoles, AoIP interfaces, Intercom User Panels and audiocodecs are connected to the same router, creating a global, flexible, and if required, redundant system that takes advantage of the simplicity and flexibility that IP technology provides in terms of for example wiring. I allows for communications with the same audio quality that was previously only reserved for contribution and broadcasting.
Commentary Systems for Olympics and other large events constitute a third field of application that AEQ has been working on for almost 30 years. This year, it is really worthwhile paying a visit to our stand, dedicated to the concept of technological convergence with the AoIP Intercom Systems.
The approach we have taken now allows us to have access to simpler systems and combine them with the Intercom system, for example in mobile units. We have developed a new AoIP-based Commentary Unit. One of its three commentator channels can operate as a User Panel in an Intercom System: when connected to a mixed matrix such as the one described above, On-Air and return audio are handled by the main Matrix while coordination is processed in the Intercom sub-matrix and from the commentator channel in use as an intercom user panel and as the rest of panels deployed in the studio or the venue.
It can also operate in other scenarios:
- As a Stand Alone unit, as all the mixing and signal selection is done locally, using only the local inputs and outputs to communicate with the outside world.
- Connected to a Dante or AES 67 system, such as consoles, analog or digital interfaces, MADI or audiocodecs, from any compatible manufacturer.
- Connected to a large commentary system, together with other tenths or hundreds of Commentary Units to provide service at a large event.
In this last case, and also when operating with Intercom matrixes, the switch inside each Commentary Unit allows the connected Gigabit Ethernet cable which is deployed to communicate the units to transport video, data or Internet access for commentary guidance.
