Method for processing video data from an uncertified video source

A method for processing a data stream from an uncertified video source, said data stream being intended to be displayed at least partially on a display screen of a cockpit of an aircraft, said display screen having predetermined dimensions and a predetermined resolution, said processing method comprising:

• a step wherein the uncertified video source delivers the data stream;
• a step wherein the data of the data stream are configured so as to adapt said data to the dimensions and resolution of the display screen of the cockpit;
• a pilot being able to interact with the display screen in the cockpit, a step wherein interaction coordinates are transferred to the uncertified video source via an adapter so that the uncertified video source delivers data of the stream in accordance with the interaction between said pilot and the display screen, said processing method further comprising:
• a step wherein a calibration mode is switched to, said calibration mode comprising, on the one hand, selection on the display screen of the cockpit of a window of interest by the pilot, and on the other hand, an operation of cropping the stream depending on said window of interest;
• a step wherein a portion of the data stream corresponding to the selected window of interest is displayed on the display screen.
