firstly its impressive to hear of a small independent media outlet getting a prestigious opportunity like this in the days of the huge mediacorps normally taking over everything. and clearly you must have the blessings of Anfield to get all this kit into the stadium in the first place.
I can guess what is going on here - you've probably got an agreement with a PR/marketing person for the reporting.
They may even think you are a traditional radio station, and that remote audio is being sent the old way using a high power VHF or UHF analogue transmitter like a big radio microphone, or even just a GSM mobile telephone circuit or other point to point link and therefore your techies handle all the provision of this, whilst the laptop is used for basic web based comms without audio streaming.
This is still one way of doing it but more resource intensive, the kit and JFMG/Ofcom fees are not cheap, and someone has to sit at the office instead of Anfield and operate the mixer unless you've got automation on that as well (even then I wouldn't chance it for a footy match as the timings vary).
The Anfield ICT folk might be paranoid that if everything was left too loose, that hackers would get into the players' / managers private comms and perhaps understandably so, its already been proven the meedja will use illegal tactics if these are not mitigated against. Football players may be security-aware against "hard" physical threats but not always the "soft" risks..
all this can be sorted out with a bit of prior testing and maybe having a contact on hand at anfield who can deal with last minute tech issues. I would expect at least one of the ICT techs at a football stadium would be not just curious but supportive of what you are doing...
No mate, Liverpool FC are fully aware of who we are and what we do and have granted us "club level" media accreditation, which basically means that anything that they do themselves outside the auspices of the Premier League or UEFA (such as yesterday's friendly) they will let us into, this includes selective press conferences and big announcements and a monthly group interview with Brendan Rodgers the club manager.
Yesterday, we had full media accreditation at Anfield, including the press room before and after the match, a seat in the press box for the match itself and 2 "press conferences" with both team managers after the game (translation: inane questions from the fella from Sky for 10 minutes).
Myself and other people who I have brought into the station are longstanding supporters who have been round the world and back watching Liverpool, hence the idea behind the station, so although the club have tried to ignore us, we kept turning up in all kinds of places and getting surreptitious interviews with the players and latterly the new manager, until finally they got back to us and agreed to let us in the door!
Good eh?
Meantime, I am the techie, the presenter, the interviewer, the announcer and everything else and I'm not very good at any of it!!
