PROBLEM TO BE SOLVED: To prevent continuity of moving images, to be reproduced by a client terminal, from being lost, when switching a part of the original moving image data transmitted from a moving image transmission server to a client terminal.SOLUTION: An extension division moving image data holding section 12 holds the extension division moving image data 61-64, i.e., the moving image data of extension division areas 61a-64a obtained by extending the division areas 51a-54a, dividing the video area 50a of the original moving image data, in the direction of other adjacent division area, so that the mutual overlapping range with other division area goes above the size of a focus area 70. When recognizing that the focus area 70 is located in the overlapping range, and the focus area 70 is displaced to the outside of the video area of the extension division moving image data, a moving image data transmission unit 13 transmits the extension division moving image data for transmission to the client terminal, while switching to the extension division moving image data corresponding to other extension division area overlapping in the displacement direction of the focus area 70.SELECTED DRAWING: Figure 3 |
