South Korean SBS TV station apologized to the Beijing Organizing Committee for its exposure of the opening ceremony. In fact, although SBS claims that it exclusively shot the footage, there must be more than one media that has the footage of the rehearsal of the opening ceremony. Because for registered media, if they want to shoot a little bit of the rehearsal footage inside the venue, it's not difficult. First, the broadcaster has the opportunity to use the debugging equipment to take pictures. Second, if you live in the media village next to the Bird's Nest, you can hang the lens out to take pictures. Third, during the rehearsal, there are still some security loopholes. Some media successfully brought cameras into the field because there were too many gates and some of the volunteers guarding the gate were not sure whether these registered media with yellow plates were allowed to enter. Fourth, more than 70,000 audiences, although they are not allowed to take pictures, if someone takes pictures secretly, it may not be found on the spot.
