A Head-Mounted Display (HMD) is provided which comprises a camera configured to capture a video of a real-world scene with a first field-of-view (FoV), a network interface circuit configured to stream video to a receiving display device, and processing means which is operative to generate a 3D model of the real-world scene, and to generate a video from the 3D model using a second FoV which is wider than the first FoV. The processing means is further operative to estimate a motion of the camera, and to stream the generated video to the receiving display device if the estimated motion of the camera satisfies one or more conditions indicative of rapid motion, else stream the captured video to the receiving display device.
