  • Publication number: 20200051321
    Abstract: Aspects of the subject disclosure may include, for example, analyzing video content obtained from a 360 degree camera to discern a point of interest in the video content and obtaining information about a viewer of the video content. A field of view is predicted based on the information about the viewer and the analysis of the video content. Less than 180 degrees of the video content centered on the predicted field of view is sent to equipment of the viewer. A monitored line of sight of the viewer is obtained based upon eye movements of the viewer relative to an orientation of the viewer. The analysis is updated based on the monitored line of sight and the predicted field of view is updated based on the updated analysis. Other embodiments are disclosed.
