This is the workflow..
At the baseball field.. I have one person with EVO on 1st base side, one person with EVO on 3rd base side, one person with EVO on top of press box. 4th person is doing play-by-play in the press box, with a fixed camera on pitcher/batter. Play-by-Play person is wearing a hands free headset, plugged into the 3.5mm input on the EVO. All 4 people are "Producers" into our channel. Using QIX they start the streams from their cameras, sending it to the Studio.
Director is watching all 4 cameras in the studio, picking and choosing which camera to go live with..
There is no "internet" available at the park, so the mix can't be accomplished using a procaster, tricaster or wirecast.. we have to use the online resources available. UStream doesn't offer a webstudio, LiveStream does.
However - LiveStream's studio will not allow you to split the audio from the camera, so viewers will "hear" whatever audio the camera is sending.
So the work around is to get the same audio to all the cameras. we have available to us a low power FM transmitter. thought was we could take the play-by-play and run into the FM transmitter.. have each camera operator with an FM radio tuned to that station. run that audio into the cell phone camera. now.. when the camera switch, they will all have same audio.
I realize we will have latency issues and that the sound isn't going to 100% match up, but much better then switching to camera 3 and hearing Joe Parent screaming at Billy.
