A moving picture suitable for display on a mobile telephone is displayed comparatively quickly. When a moving picture is requested, a leading segment of the moving picture is converted. The leading segment has an amount of data which, after the conversion, is less than the amount of data that is displayable on the mobile telephone that issued the request. A succeeding segment, which can be converted while the leading segment is being transmitted to the mobile telephone and viewed by the user of the mobile telephone, is converted. If there is a request for the succeeding segment after the leading segment is viewed, the conversion of the succeeding segment will be finished by the time of the request for succeeding segment. As a result, the succeeding segment can be transmitted to the mobile telephone quickly, and it can be viewed rapidly. |

1. A computer implemented method comprising:
receiving, by a computer system, a request for a moving picture file from a client terminal; converting, by the computer system, a leading segment of the moving picture file; transmitting, by the computer system, the converted leading segment to the client terminal; converting, by the computer system, a succeeding segment of the moving picture file that follows the leading segment; receiving, by the computer system, a request for the succeeding segment from the client terminal; in response to the request for the succeeding segment, transmitting, by the computer system, the converted succeeding segment to the client terminal; repeating, by the computer system, conversion of next succeeding segments of the moving picture file that follow the succeeding segment; and controlling, by the computer system, the repeated conversion of the next succeeding segments wherein, after determination that a request for a second succeeding segment following a first succeeding segment is not received before conversion of the first succeeding segment ends, conversion of the second succeeding segment is not performed. |
