Abstract: In the conventional system, although a viewer can feel only part of the atmosphere of the hall while viewing images of a live performance etc, the viewer cannot enhance the mood and cannot get a feeling of participating in the live event. An image display system of the present invention is a system for displaying an image reflecting a motion of a viewer outside a hall for live performance etc. on a display being installed in the hall. Specifically, the system simultaneously transmits the image of the live performance etc. in the hall to a terminal for viewing of the viewer, receives motion information indicating the motion of the viewer outside the hall, thereby controlling display of the image on the display on the basis of the motion information.

Abstract: Conventionally, a system for real-time distribution of images of the various productions of the stage to user terminals on the network has been provided. However, it is nothing but an image, the viewer can hardly feel for participation in the performance including the production. In order to solve the above deficiency, the present invention provides a stage production system, which receives an entry of a comment for distributed live image of the stage from the user terminal on the network, promptly displays the comment in a viewable state for a viewer of the distribute live image on a display, and controls the production equipment on the real stage such as the lighting equipment, sound equipment, and smoke machine.

Abstract: A user management server stores access information which is created by associating each item of access identification information, which identifies an access destination in accordance with the number of users who have been permitted to connect to it, together with access conditions which show the attributes of users, and with user identification information which identifies the user terminals associated with this access destination, and with connection destination information which identifies a comment storage section where the comments transmitted from the user terminals are stored, and when a connection request is received from a user terminal, then if a vacancy exists in the access information which has been associated with the corresponding access conditions, the connection is permitted, and if a comment server receives a comment transmitted from a user terminal, it shares this comment with the user terminals with which this same connection destination information has been associated.

Abstract: A first terminal device includes an input unit which inputs operation information indicating operation content, and a first transmission unit which transmits packet information including operation information input from the input unit and destination information for designating a second terminal device, which is a transmission target of the operation information among a plurality of terminal devices to an operation information transmission server. The operation information transmission server includes a first reception unit which receives the packet information transmitted from the first transmission unit and a second transmission unit which refers to the destination information included in the received packet information and transmitting the packet information addressed to the second terminal device corresponding to the destination information.
