When a video-reproducing device detects a jumping movement of a user, the video-reproducing device determines that an instruction is given to move a viewpoint position to a place on which a target mark is displayed, and transmits a request for stopping transmission to a video-providing device as a transmission source of a currently displayed video, and transmits a request for starting transmission to a video-providing device as a moving destination. When transmission of a video from the video-providing device as the moving destination is started, the movement in viewpoint is achieved, and a video captured from a new viewpoint position is allowed to be viewed on the video-reproducing device. ## Claims ### Claim 1 A display device comprising: a spherical display unit; a reception unit configured to receive an image from an external device; a sensor unit configured to measure a line of sight, a head position, or a posture of a user; a control unit, wherein when a first image received from a first external device is displayed on the display unit, the control unit receives a second image from a second external device included in the first image, on the basis of at least one of a line of sight, a head position, and a posture of a user measured by the sensor unit, and the control unit causes the display unit to display the second image; and a transmission unit configured to transmit information to the external device, wherein the control unit transmits information measured by the sensor unit to the second device to display the second image. ### Claim 2 A display device comprising: a spherical display unit; a reception unit configured to receive an image from an external device; a sensor unit configured to measure a line of sight, a head position, or a posture of a user; a control unit, wherein when a first image received from a first external device is displayed on the display unit, the control unit receives a second image from a second external device included in the first image, on the basis of at least one of a line of sight, a head position, and a posture of a user measured by the sensor unit, and the control unit causes the display unit to display the second image; and a sound collection unit, wherein the control unit transmits audios collected by the sound collection unit to the external device. ### Claim 3 A display device comprising: a spherical display unit; a reception unit configured to receive an image from an external device; a sensor unit configured to measure a line of sight, a head position, or a posture of a user; a control unit, wherein when a first image received from a first external device is displayed on the display unit, the control unit receives a second image from a second external device included in the first image, on the basis of at least one of a line of sight, a head position, and a posture of a user measured by the sensor unit, and the control unit causes the display unit to display the second image; and a measurement unit configured to measure pressure acting between a user's foot and a ground surface with which the user's foot makes contact, wherein the control unit switches the first image and the second image to control display according to a result of measurement by the measurement unit.
