Image data is communicated from a source system to a target system. At the source system, a background environment map is generated and communicated to the target system. The source system then captures a source image from position and field of view of a camera. In addition, the background environment map is rendered according to the position and field of view of the camera to generate a background image visible for the position and field of view of the camera. A difference image is generated representing difference between the source image and the background image. Finally, the difference image and the position and field of view of the camera is communicated to the target system. At the target system, the background environment map is received from the source system. In addition, the difference image and the position and field of view of the camera is received from the source system. The background environment map is rendered according to the position and field of view of the camera to thereby generate a background image visible for the position and field of view of the camera. Finally, a target image based upon the background image and difference image is generated for display.
