摘要： PROBLEM TO BE SOLVED: To easily distribute a fast forward image in a stable response without provision of the fast forward image as a separate image file. SOLUTION: A moving image information file connected to a medium server is configured as shown in figure. That is, moving image information is divided into plural image information divisions, which are assigned and stored in storage devices 201-20n sequentially. When a distribution request of moving image information is made via a communication network from a terminal equipment, the medium server reads the image information divisions of the moving image information on request in the order of, e.g. 211, 212,..., 2mn and distributes them. When a fast forward request comes from a terminal equipment during the distribution, succeeding image information divisions only from the storage device from which the image information divisions are read out at a point of time of the fast forward request and distributed. For example, when image information division 212 of the storage device 202 is read out and the fast forward request is made, the image information divisions 222, 232,..., 2m2 are read out of the storage device 202 and distributed.
