Conditional forced perspective in spherical video

Abstract

A processor-implemented method in a digital media player includes receiving data defining a user's viewport in relation to spherical video frames displayed by the digital media player; and where a forced perspective event is to be triggered at the time of display of a spherical frame, triggering the forced perspective event conditionally based at least on the orientation of the user's viewport in relation to the spherical video frames. A digital media player includes processing structure for receiving data defining a user's viewport in relation to spherical video frames displayed by the digital media player; and processing structure for, where a forced perspective event is to be triggered at the time of display of a spherical frame, triggering the forced perspective event conditionally based at least on the orientation of the user's viewport in relation to the spherical video frames.
