Abstract: The present disclosure relates to a method of providing a video stream from a system comprising a main unit and a plurality of sensors, wherein the main unit is configured to receive data from the plurality of sensors, the method comprising the steps of: transmitting a multi-view video stream from the main unit to a client, wherein the multi-view video stream represents a multi-view composed of sensor data views from the plurality of sensors in the system; receiving, in the main unit, a command from the client representing a zoom-in operation; computing an updated multi-view according to the received command; evaluating if the updated multi-view includes an area outside a dominating sensor data view in the updated multi-view that is greater than a predetermined threshold; if the area outside the dominating sensor data view is greater than the predetermined threshold, transmitting a multi-view video stream representing the updated multi-view; if the area outside the dominating sensor data view is less than, or equal to, the predetermined threshold, transmitting a single-view video stream representing the dominating sensor data view. The present disclosure further relates to a system for providing a video stream comprising sensor data views.
