Abstract:
1. A transmission device, comprising: a video signal receiving portion that receives video data for one of a three-dimensional display and a two-dimensional display; a first transmission portion that transmits the video data and a display information that pertains to (i) one of the three-dimensional display and the two-dimensional display of the video data, in which the display information that pertains to pre-display processing of the three-dimensional display of three-dimensional content in form of three-dimensional images is transmitted only when the video data being received is three-dimensional content to be displayed, and (ii) switching display of images of the three-dimensional images of the video data from three-dimensional image display format to two-dimensional image display format and from the two-dimensional image display format to the three-dimensional image display format, to a receiving device through a transmission path; and a second transmission portion that transmits, when the video data being transmitted is the three-dimensional content in the form of the three-dimensional images, the display information to the receiving device through a bidirectional communication path that is configured using a specified line of the transmission path, wherein the specified line is other than a first communication path of the transmission path through which the first transmission portion transmits the video data and the display information to the receiving device, wherein transmission of the display information by the first transmission portion and the second transmission portion is in accordance with a determination of in which of a first area and a second area in digital broadcast data the display information is located, the first area being different from the second area.
