Questions - and solutions

Questions of an amazed broadcaster who still uses the old technology:

How does it work?

We virtualize your studio resources, such as telephone system, radio automation system, codecs, and commentator mics (i.e. newscaster). As usual, you are ready for schedule-related challenges as they occur with self-op studio technology.

How does it feel?

It’s almost like at home, just outside. Local sources, meaning moderator and guest microphones, radio link, local CD player, etc., are on the same mixing console panel as the ‘virtual’ sources from the station.

Can we use it to create regional studios?

Yes, most definitely. Regional studios access the central (and well-kept) resources of the main broadcast centre. Mixing of local and central signals can either be facilitated through the main broadcast centre or in regional studios which can then be added through signal distribution.

Can we “centralize” with it?

You can access any show from anywhere and even “take over” the local studio from the broadcast centre, making close to every workflow compatible to our solution.

What transmission technology is required?

Not much. In an ISDN environment, a maximum of 128kbit (equal to 2B channels) suffices, as most transmissions from the VRS consist of voice. With an IP connection (AoIP / SIP), it comes to approximately 140kbit for the audio transmissions – this already includes the command line. The same data transmission rate has to be added on to that for the visualization. All of this is possible, as all music elements, such as soundtracks, commercials, trailers, jingles, contributions, and canned music are played in the broadcast centre.

But doesn’t new technology like this run very unstable and with many, many problems?   

Quite on the contrary. With a considerably higher redundancy than before with the external studio broadcasting the entire schedules. Even an interruption in the connection between broadcast centre and the outside location would only be felt when moderations are ongoing at the same time. The signals from the broadcast centre remain unaffected. Should the connection still drop at some point, we have integrated clear signalling for the moderator.

In a nutshell

SLG Broadcast AG distributes and integrates systems for radio and TV applications.

As a non-independent system supplier, we integrate only systems of which we are the experts - and do not depend on the knowhow of a manufacturer.
