First Claim
1. A moving image distribution system for distributing a prespecified moving image to a user terminal connected to the system via a network, said system comprising:
- a moving image dividing unit for dividing said moving image into two not-reproducible moving image files along the time axis;
an encrypting unit for encrypting one of the divided moving image files by CM file data separated from the moving image and selected as desired, said CM file data including a prespecified CM element incorporated therein;
a moving image distributing unit for distributing to the user terminal one of the encrypted moving image file with the CM file data in response to a request for reproduction from the user terminal previously storing therein the other divided moving image file; and
a reproducing unit for decrypting the encrypted moving image file and the other divided moving image file distributed to the user terminal by using the CM file data and reproducing the decrypted files.

Abstract
A moving image distribution system, wherein the user can view content moving images at no charge, and the provider of the content moving images can prevent a drain of the moving image contents and can protect the copy right thereof, as a copy right holder, without fail. The moving images are divided, along a time axis, into two master and slave nonreproducible moving image files. The slave moving image file (small file) is encrypted based on CM file data in which a predetermined CM element has been incorporated. In response to a reproduction request of a user terminal that possesses the master moving image file (main file) in advance, the slave moving image file is distributed with the CM moving images to the user terminal via a network line such as the Internet.
