The invention discloses an internet-based resource supplying system comprising a resource sever, a supply platform and a user terminal, wherein the resource server provides a link of a program resource; the supply platform generates an order according to the link of the program resource provided by the resource server, and pushes the order to the user terminal; and the user terminal conducts analysis to the received order, logs in the resource server according to the analyzed link of the program resource, requests for providing a downloading service, and stores the downloaded program resource. By adopting a supply business mode, the internet-based resource supplying system provides high-definition audio-video program resources for a user, and the user does not need to carry out manual downloaded operation and can complete the automatic supply of the program resource, thus improving the simpleness and convenience of the operation of the user. The supply business is custom-made at an idle period of the network, thus being capable of effectively utilizing the user home bandwidth resource provided by a based network provider, indirectly saving the cost for the home user, and avoiding the adverse effect caused by long-lasting downloading and waiting on the user.
