How to live link an event to a tv without internet?

Help I need someone tech minded! I have a big event coming up and my grandma is too frail to attend but I want her to see everything as it happens. Neither of us are technically minded but her especially so it can't be too complicated. Ideally I'd like her to be able to see it on her own tv but she can use an iPad. Originally I was going to have someone at the event FaceTime her but she doesn't have Internet and nor does the venue, also there is bad phone reception at the venue so I don't think 3G will work either. If anyone has any suggestions as to how to get around this it would be much appreciated!
