1. A method comprising:

  • receiving head-tracking data that includes yaw, pitch, and roll values that describe one or more positions of people as a function of time while the people are viewing a three-dimensional video;

    generating one or more user profiles of one or more persons of the people based on characteristics associated with the people;

    generating video segments from the three-dimensional video; and

    for each of the video segments for the one or more user profiles of the one or more persons;

    determining a directional encoding format that projects latitudes and longitudes of locations of a surface of a sphere onto locations on a plane based on the yaw, pitch, and roll values from the head-tracking data for the one or more persons;

    determining a cost function that identifies a region of interest on the plane based on the yaw, pitch, and roll values from the head-tracking data for the one or more persons; and

    generating optimal segment parameters for the one or more user profiles that minimize a sum-over position for the region of interest.
