A plurality of video input units generate video frames and provide shooting characteristics. A 3D video frame generator creates a 3D video frame by combining a plurality of video frames, which are provided from the plurality of video input units, respectively, and provides 3D video frame composition information indicating a composition type of the plurality of video frames included in the 3D video frame, and resolution control information indicating adjustment/non-adjustment of resolutions of the video frames. A 3D video frame encoder outputs an encoded 3D video stream by encoding the 3D video frame provided from the 3D video frame generator. A composition information checker checks 3D video composition information including the shooting information, the 3D video frame composition information, and the resolution control information. A 3D video data generator generates 3D video data by combining the 3D video composition information and the encoded 3D video stream.
