Rectilinear viewport extraction from a region of a wide field of view is described using messaging in the video transmission field. Some embodiments pertain to a method that includes receiving a wide field of view video, receiving position data from a remote coupled user device, selecting a region of interest in the video based on the received position data, extracting the region of interest from the video, generating region metadata describing the extracted region of interest, encoding the extracted region of interest of the video, and transmitting the encoded video with the region metadata to the user device.
