1. A method for teletransmitting to a remote processing site a video stream captured at a scene of intervention, the method comprising:
on the intervention scene:
capturing the video stream on a unit or object within the intervention scene, from a portable equipment held by a field operator at the intervention scene;
modifying the captured video stream in such a way that content in one or more zones of interest is erased from the captured video stream, including a step for modifying contextual characteristics of the captured video stream that allow determination of a location of the unit or object; and
transmitting the modified captured video stream from the intervention scene to a remote teleprocessing site via one or more communication networks;
on the remote teleprocessing site:
receiving the modified captured video stream from the intervention scene via the one or more communication networks;
processing the modified captured video stream so as to be enriched by addition of instructions or orders by augmented reality techniques; and
returning the enriched video stream to the portable equipment via the one or more communication networks and displaying the enriched video stream on the portable equipment, to provide remote assistance to the field operator.
