1. A video display system for displaying a display video via a display device, the video display system comprising:
an observation device including a capturing unit configured to capture a wide-angle video, a data obtainment unit configured to obtain data related to a movement direction of the capturing unit, a metadata composition unit configured to obtain metadata based on the data obtained, and a transmission unit configured to transmit, together with the metadata, the wide-angle video captured; and
a VR device including:
a reception unit configured to receive the wide-angle video and the metadata;
an orientation estimation unit configured to estimate an orientation of the display device;
a differential calculation unit configured to calculate a relative movement direction based on a difference between the orientation of the display device estimated and the movement direction of the capturing unit in the metadata, the relative movement direction being a movement direction of the capturing unit relative to the orientation of the display device;
a presentation unit configured to present the relative movement direction calculated to a user of the display device;
a video generation unit configured to generate, from the wide-angle video received, the display video including a portion corresponding to a viewing area corresponding to the orientation of the display device as estimated by the orientation estimation unit; and
the display device that displays the display video.
