1. A method of video-content filtering for selective dissemination comprising:
acquiring a panoramic signal organized into indexed frames;
generating a display of the panoramic signal;
initializing a pivotal gaze position and a pivotal frame index as default values, and a gaze count to equal zero;
detecting gaze positions at regular time intervals;
measuring durations of visual fixations of a viewer of the display based on detecting the viewer's gaze positions;
for each visual fixation attaining a prescribed duration threshold:
determining a respective pivotal gaze position;
extracting a segment of the panoramic signal corresponding to a view region, of prescribed shape and dimensions, surrounding the respective pivotal gaze position; and
transmitting said segment to an information-dissemination facility.
