What are the three broadcast languages of Beijing Olympic Games?

Etiquette for the opening ceremony of the Olympic Games must be introduced in three languages, and the broadcast sequence is English, French and the language of the host country (if its official language is not English or French). If the language of the host country is English, it will be placed after the French broadcast. All etiquette items must be translated, not all broadcast, but what is not broadcast must be displayed on the big screen in the form of subtitles. The translation scheme (such as what to broadcast and what subtitles to add) must be approved by the International Olympic Committee.
