The first and second images include first and second numbers of pixels. The first and second images are arranged according to a shared coordinate system to portray different perspectives of a common scene. A first portion of pixels are removed from the first image based on a filtering of the first image, resulting in a first remaining number of pixels. A second portion of pixels are removed from the second image based on positions of the first portion of pixels in the shared coordinate system, resulting in a second remaining number of pixels. The first remaining portion of pixels is combined with the second remaining portion of pixels to form a transport frame for delivery to a media processor. Other embodiments are disclosed. ## Claims ### Claim 1 A device, comprising: a memory that stores executable instructions; and a processing system including a processor coupled to the memory, wherein responsive to executing the instructions, the processing system facilitates performance of operations comprising: receiving three-dimensional image content comprising a left-eye frame and a right-eye frame, wherein the left-eye frame comprises a first image comprising a first plurality of pixels and the right-eye frame comprises a second image comprising a second plurality of pixels, wherein the first image and the second image portray different perspectives of a common scene collectively forming a pair of images of the common scene;
