Monitoring system for remotely supervising and controlling critical operations and algorithm for detecting image freezing, consisting of a system for displaying images from a set of sensors in real time, with the ability to detect the freezing of part or all of the input video signal and to detect the failure or non-existence of an input video signal in order to inform the operator by means of sound, indicating lights or overlays on the display, and with the ability to select an alternative video signal input in order to avoid the operator being able to lose sight of the images of the real world being displayed or to avoid a delay being produced in the viewing of such images. The invention also relates to an algorithm for performing the above functionalities on the basis of the use of one or more computing units.
