Claim 0:
1. A transmitting device configured to transmit, to a receiving device, a plurality of video signals captured from different positions, the plurality of video signals being grouped by a plurality of groups depending on imaging positions at which the video signals are captured, the transmitting device comprising:
a controller configured to assign an ID for identifying each of the plurality of groups, wherein the controller is further configured to:
specify a request ID that is an ID of a video signal corresponding to a change of a viewpoint position of a user of the receiving device; and
a communication interface configured to transmit a video signal to which the ID is assigned, to the receiving device, the communication interface further transmits the video signal to which the request ID is assigned, to the receiving device, wherein the communication interface is further configured to:
transmit a plurality of video signals necessary to generate video corresponding to the viewpoint position of the user in a video signal group to which the request ID is assigned, when the request ID is same as an ID of an immediately previously transmitted video signal; and
transmit a default video signal in the video signal group to which the request ID is assigned, when the request ID is different from the ID of the immediately previously transmitted video signal.
