Abstract:
Appropriate reduction of transferred data volume is used to deliver interruption-free video to a user, minimizing viewing discomfort. A head-mounted display secured to the head of a user and a video generating device that generates a video for presentation to the user by the head-mounted display are combined in a video system. In the head-mounted display, a presentation unit presents the video to the user, an imaging unit captures an image of the user's eye, the first communication unit sends the captured image to the video generating device, and receives the video from the video generating device. In the video generating device, a second communication unit receives captured images from the head-mounted display and sends a video to the head-mounted-display, a gaze point acquisition unit acquires, based on the captured images, the gaze point of the user in the video, a calculation unit defines a designated region based on the acquired gaze point, and generates the video, wherein the data volume per unit pixel count used for the exterior of the designated region is reduced compared to the data volume used for the interior of the designated region.

Claim (Index 8):
A video system comprising\n a display used for presenting an image to a user a video generating device for generating a video to be presented by the display, and a video distribution device for delivering video to the video generating device, wherein the display comprises\n a video presentation unit for presenting the video to the user, \n an imaging unit for capturing an image of an eye of the user, and \n a first communication unit for sending the image captured by the imaging unit to the video generating device and for receiving from the video generating device the video for presentation by the video presentation unit; and \n the video generating device comprises\n a second communication unit for receiving from the display the image captured by the imaging unit and sending the video to the display, \n a gaze point acquisition unit for acquiring the user's gaze point in the video based on the images captured by the imaging unit, \n a gaze point motion acquisition unit for acquiring the movement of the user's gaze point based on the gaze point acquired by the gaze point acquisition unit, and \n a third communication unit for sending the gaze point acquired by the gaze point acquisition unit to the video distribution device and receiving the video corresponding to said gaze point from the video distribution device; and \n the video distribution device comprises\n a fourth communication unit for receiving gaze point information from the video generating device and sending video data corresponding to the gaze point information to the video generating device, and \n a distribution video calculation unit for generating the video by\n defining a designated region based on the gaze point information received by the fourth communication unit, \n using the gaze point as a reference, to set a designated region having a shape defined by a major axis and a minor axis, or a long edge and a short edge, \n setting direction of the major axis or the direction of the long edge of the designated region according to the movement direction of the gaze point received by the fourth communication unit, and \n generating the video with a reduced video data volume per unit pixel count outside of the designated region, compared to the video calculated for the inside of the designated region.
