The two ceremonies will be conducted in french, we are in Monaco, the language is french.but I think the reporter will translate for the strangers.
There was a documentary last week on the wedding at the french tv. A man of the palace said there were many tv of different countries which ask to be there for boatdcasting the wedding, TV of europa, tv of Australie, japan and also a chinese tv. He said that there will be many cameras and for the tv which wants to show his own representants, there would be privat camera who will show them during the ceremony. For example, if the belgia tv wants to show the crown prince couple during the ceremony, there will be (if the tv wants) a privat camera which can show the princes during the ceremony.
The concert of Jean Michel Jarre will be boardcast internationaly, and you tube will boardcast.
I saw on Monaco info, a report of the repetions of the offering of the bouquet to the sainte Devote, it will be very beautiful with songs. It will be boardcasted.
every day, we have news on the wedding, to day, there is a report on Monaco Matin which talks about the news trumpets for the carabinieries.
The ZDf tv asks to be there all the day, the tv wants to show the entry of the royals and dignitaries at their hotel, the tv wants to be at the place of the palace to show what happens during this day before the ceremony and after the ceremony.
