Live remote broadcasting - some notes

Reply to Jay's inquiry about livecasting his show remotely:

Live broadcasting would require that you have access to preferably wired broadband internet at the venue; a computer than can run Winamp and Shoutcast; a mixer, mics and peripherals you might need such as CD player; and also of course the consent of the venue to broadcast from that space for that period of time. It is possible to do live broadcasting over a phone line as well, we have the equipment, although that sound is likely to be a bit thinner. And of course you'd have to tie up a phone line for the duration of the show..

There are also coordination issues with live broadcasting over internet. We would have to have someone at the controls in the station to take responsibility for the starting and stopping of the feed during the livecast, as well as covering if anything goes wrong during it. There is also an issue of "latency" (i.e., delay). From Harbour Centre to CJSF the latency was 45 seconds and we had to synchronize watches. I don't know if the latency from the venue you want to use is the same or not - would be a good idea to test it. I'm also not sure if the latency is consistent or depends to some degree on traffic - we'd have to experiment. Whoever is in the studio can play music and do a cross-fade when the signal starts to come through. It would also be valuable to have a telephone connection as well as the internet, for feedback about conditions between the two ends of the feed - though perhaps it could be done with chat. So, as you can see, live remote broadcasting isn't entirely cut and dried, especially when it's not a permanent hookup.
