[cma-l] mobile technology and community radio

We have been experimenting over the Summer with various ways of doing Outside Broadcasts. Essentially we have mikes, mixer and music source(s) plus a laptop PC creating a stream broadcast over the Internet which is then picked up in the studios. In theory we can use a direct Ethernet connection or WiFi if available at the remote location or 3G otherwise. However Ethernet is rarely available and we have found WiFi unreliable so have opted for 3G which works well. We got a 3G dongle for $)G"g30 from 3 which lasted us through the whole Summer!

The only major problem with this setup is that there is a delay of several seconds which can cause problems if we are interacting with a presenter in the studio. We tried various combinations of presenter in studio with reporter on remote site, presenter at remote site with music coming from studio and broadcasting the whole programme from the remote site. Perhaps surprisingly the latter worked best as it avoided problems working with the delay.

The technical solution to the delay is to use special "black boxes" called Instreamers and Extreamers although these are expensive ($)G"g200 or so each). But running the whole programme from the remote site works very well as long as the broadband link stays up.

The other main lesson is that it is essential to have a technical operator at the studios all the time during an OB, with a direct communications link (mobile phone usually although it could be Skype).

I think we have been surprised that this setup can produce such a good quality link from an external site using just a few $)G"g100s of equipment. Only a few years ago such things required van fulls of equipment and a staff of dozens - at least for the BBC!
