Provided is a video processing device that quickly identifies a distribution mode of a stream of display data, e.g., subtitles, and reproduces the data according to the distribution mode. The video processing device receives a transport stream including additional information and a data stream of display data to be displayed along with a 3D video, the additional information indicating whether the transport stream further includes left-view and right-view data streams generated from left-view and right-view data used for displaying the display data; determines whether the transport stream includes the left-view and the right-view data streams based on the additional information; and reproduces the left-view and the right-view data from the left-view and the right-view data streams when the transport stream includes the left-view and the right-view data streams, and reproduces alternative left-view and right-view data when the transport stream does not include the left-view and the right-view data streams.
