A new tactic analysis of broadcast sports video is proposed based on player trajectory information. Tactic analysis of sports video aims to recognize and discover tactic modes and match strategies that teams and personal players used in the games. Based on players and ball trajectory. First presents an interactive relationship analysis of temporal and spatial algorithm based on time fragment slice. According to the speed and distance of trajectory shape and the distance measurement and each trajectory in time fragment, to use graphical model was constructed to express tactical video game sports event. Through the analysis of each component fragment of interaction trajectory, the offensive incidents of tactical mode carried out hierarchical recognition of coarse to fine in football game video. In the coarse recognition process, the interaction mode is divided into a coordinated attack and personal attack. In fine recognition further, the coordinated attack mode is divided into interception attack and no interception attack. The personal attack mode is divided into direct attack and the dribbling-attack.
