Claim:
1. A video transmission device for transmitting video content to a video playback device, the video transmission device comprising: a non-transitory memory configured to store therein 3D video content corresponding to 2D video content; an encoder configured to encode images of one of two viewpoints constituting the 3D video content by using a first encoding scheme and generate a video stream of the 2D video content, and to encode images of both of the two viewpoints by using a second encoding scheme that is different from the first encoding scheme and generate a video stream of the 3D video content; and a processor configured to transmit, via a communication circuit, the video stream of the 2D video content, the video stream of the 3D video content, information defining a program relating to the 2D video content, and information defining a program relating to the 3D video content, wherein the information defining the program relating to the 3D video content includes linkage information for identifying the information defining the program relating to the 2D video content, the processor transmits identical-status information by including the identical-status information in the information defining the program relating to the 3D video content, the identical-status information indicating that the images of the one of the two viewpoints correspond to the 2D video content, and the identical-status information is to be received by the video playback device.
