If identical events in the video stream can be recognized,
it will become useful information for organizing continuous media.
In broadcasted sports video, there are scenes called ``replay'' which include
important events identical to the live scenes.
In this paper, we propose a new method for detection of identical events
by analyzing and matching of the live and replay scenes for broadcasted
video of American football.
The proposed method pays attention to camera works,
because we consider that the works of different cameras
that track identical events may move in a similar way.
The basic experimental results show that this method is effective for
detection of identical events.
