Patent ID: 8687950

Claim:
An electronic apparatus which plays two-dimensional (2D) video data or three-dimensional (3D) video data, comprising: a first converter configured to generate a plurality of three-dimensional video frames corresponding to a plurality of two-dimensional video frames in the two-dimensional video data; and a display controller configured to control displaying the plurality of three-dimensional video frames generated by the first converter on a screen if three-dimensional play of the two-dimensional video data has been requested, and to control displaying a plurality of three-dimensional video frames in the three-dimensional video data if play of the three-dimensional video data has been requested, wherein the display controller is configured to control displaying the plurality of two-dimensional video frames in the two-dimensional video data on the screen if a change of a play speed has been requested during the three-dimensional play of the two-dimensional video data, and the display controller is configured to maintain the display of the plurality of two-dimensional video frames on the screen and to control displaying on the screen a message indicating that the three-dimensional play of the two-dimensional video data is disabled during the change of the play speed, if the three-dimensional play of the two-dimensional video data has been requested while the plurality of two-dimensional video frames in the two-dimensional video data are being displayed on the screen by the change of the play speed having been requested during the three-dimensional play of the two-dimensional video data.
