Abstract: Provided is a method of replaying a game video using camera information calibration, and more particularly, to a method of replaying a game video using camera information calibration, in which a game video is replayed by calibrating information related to operation of a camera in a virtual space so as to provide users with game videos that are convenient to view. According to the method of replaying a game video using camera information calibration, movement of a camera that captures a video of a virtual space may be effectively controlled when replaying a game play situation so that inconvenience caused to a viewer who views the replay video is minimized and the viewer may conveniently view the game replay video for a long period of time.

Abstract: Provided are a method of recording and replaying a game video by using an object state recording method, in which recording and replaying of the game video may be performed by remarkably reducing a data capacity of the game video. According to the method of recording and replaying a game video by using an object state recording method, a game play video having a small data capacity may be provided at a high image quality. In addition, according to the method of recording and replaying a game video by using an object state recording method, a calculation load of a game play terminal may be remarkably reduced by recording a game video based on the latest game development environment.

Abstract: Provided is a method of providing a broadcasting service and playing a broadcast by using an object state transmitting method, in which a data capacity of a video may be remarkably reduced to transmit a broadcasting image and image data of the broadcasting image may be received and played. Accordingly, according to the method of providing a broadcasting service and playing a broadcast by using an object state transmitting method, a broadcasting image having a small data capacity may be transmitted, received and provided at a high image quality at the same time.

Abstract: Provided is a special video generation system for a game play situation, generating and providing a special video of a game play situation being played on a game terminal, for example, as a 360-degree video or a virtual reality (VR) video. According to the special video generation system for a game play situation, the special video of the game play situation may be easily generated without greatly increasing a calculation load of the game terminal. In addition, according to the special video generation system for a game play situation, interest of game users in playing games may be aroused by providing the special video of the game play situation.
