Abstract: A device and method are provided for delivering three-dimensional (3-D) content. The device includes a receiving unit configured to receive a first signal containing at least two-dimensional (2-D) content, a processing unit configured to (i) determine an amount of a difference in the content in the first signal to be visualized by a left visual sensor and a right visual sensor, (ii) determine whether the amount of the difference is less than or equal to a predetermined minimum value, and to discard the signal to be visualized by one of the right and left visual sensors when the amount is determined to be less than or equal to the predetermined minimum value, and (iii) generate a second signal containing the 2-D content of the first signal and 3-D content in which the first signal to be visualized by the one of the right and left visual sensor sensors is discarded.
