The relay 112 and the digital content providing server 114 are not directly connectable. Accordingly, the relay servers 132 and 134 are designed to be transferred between the digital content providing servers 112 and 114 and the terminal devices 122 and 124. The content and function of the relay server 132 is the same as that of the relay server 134'. The relay server 132 will be described below as an example, wherein the relay server 132 is assumed to be located near the terminal device 122.

Specifically, when the digital content providing server 112 and/or 114 cannot successfully connect directly with the terminal device 122, the relay server 140 acts as a relay point for both digital content delivery. That is, when the terminal device 122 does not directly connect to the digital content providing server 112 and/or U4 through the User Datagram Protocol (UDP), one-to-one or many-to-one connection is performed. The terminal device 122 performs a one-to-one or many-to-one connection with the digital content providing server 112 and/or 114 via the relay control protocol (TCP) via the relay control protocol (TCP). Accordingly, in the present embodiment, the connection between the terminal devices 122 and 124 and the digital content providing server 112 and the digital content providing server 114 can automatically find the connectable line under the coordination of the configured digital content management software. The way, therefore, the convenience of the user's connection can be improved, and the cumbersome setting can be avoided. In the embodiment, the relay servers 132 and 134 may be any of the feeder hosts or personal computers that are configured with a number of valleys. When configuring any number of servers in the management module or PCs that meet the hardware requirements, the relay server on the peer-to-peer network 160 relays the digital content/16 modules and manages the account.

However, it must be understood that 18 200908655 27444twf.doc/n This is not a limitation of the present invention, and the account management server 150 can be erected in other programming languages and databases without departing from the spirit of the present invention. In another embodiment of the present invention, the digital content delivery system 1 may further include a Network Address Translation (NAT) device 170 (shown in FIG. 4) that is connected to the terminal device 122 and/or The network locations of the terminal devices 122 and/or 124 are assigned between the peer-to-peer network 160 and the peer-to-peer network 160 in a dynamic h〇st configuration protocol (DHCP) manner. In order to reduce the IPv4 address consumption rate, ΝΑτ is widely used on servers, firewalls or routers. Since the NAT device 170 dynamically assigns the network locations (i.e., ip and port) of the terminal devices 122 and/or 124, the terminal devices 122 and/or 124 are hidden from the NAT device 170 and are not only difficult to identify but also when the terminal device 122 And / or 124 again, the network location may change. Accordingly, in accordance with the present embodiment, the digital content providing servers 112 and 114 are connected to the terminal devices 122 and/or 124 via a Dynamic NAT Traversal technique. The dynamic network address translation traversal technique is to provide an alternate of the packet streaming services in the IP domain and to enable devices in one or more public networks (e.g., peer-to-peer network 160), for example, digital content providing servers 112. And 1H) devices (e.g., terminal devices 122 and 124) that can be connected to a private network (a network formed by a NAT device 17). In particular, in this case, since the dynamic network address translation traversal technique is used, when the user (i.e., the terminal devices m and m) are on different network segments, the communication can be maintained without interruption. ^ " 19 200908655 27444twt.doc/n Based on the above-described digital content delivery system 1 according to the present embodiment, distributed digital content/service providers and terminal devices of different IP network segments can be actively activated under central account management One-to-one or many-to-one digital tribute transmission. The steps of the above-described digital content delivery system 100 for performing digital content delivery will be described in detail below with reference to Figs. 2 and 3. 2 is a flow chart showing a digital content delivery method according to an embodiment of the present invention, and FIG. 3 is a schematic diagram showing information flow in a digital content delivery process according to an embodiment of the invention. Hereinafter, an example will be described in which the terminal device 122 logs in to the account management word service 150 to receive the digital content/service. Referring to Fig. 2 and Fig. 3', first, in step S201, the digital content management module 122a is executed on the terminal device 122 to log in to the account management server 150. In particular, the digital content management module 122a of the terminal device 122 transmits the user account and password to the account management server by using the XML-RPC through the hypertext transfer protocol (Hypertext Transmissi〇n Pr〇t〇c〇1, Ηττρ). 150 to request login. Next, in step S203, the account management server 15 performs login authentication of the digital content management module 122a. If the account official server 15 is successfully authenticated in step S2〇3, the account management server 150 requests the digital content management module 122a for the network location of the terminal 122 (ie, IP and 埠) in step S2〇5. mouth). If the account management server 15 fails the authentication in step S203, the error information is transmitted to the terminal device "°f22, the content management module 122a, and the flow ends without transferring the digital content. / Service to the terminal device 122. That is to say, the system for digitally 20 200908655 27444twf.doc/n capacity / service Qian Lin makes the (four) share, the domain illegal access to digital content. In the step S207, the account management server (9) will pick up the network location transmitted by the content management module 122a. In step S209, the account management server 15 will manage the remaining IP address, friend list and friend field status according to the received position return number (4). Stomach training suit

In step S211, the account management server 15 determines the digital content/service that the account agrees to receive according to the login account, and notifies the digital provider to provide the server 112 and/or 114 (four) capacity management module and 12 Network location. Next, in step S213, the digital content providing server (1) and the domain 114 notify the connection request at the management module 122a that has received the account management server (9). Now, in step S215, the terminal device 122 determines whether the connection can be directly established through the calendar and the digital content service n 112 and/or 114. If it is determined in the step coffee, the connection can be made through the connection, then in step s2i7 The UDP is selected to directly establish a connection with the digital content providing ship 112 and/or 114. If it is determined in step S215 that the connection is not traversable, then in the step S219, the remote Tcp is selected and the feeders 112 and/or 114 are connected via the relay feeder 132. In particular, 'in the case of indirectly establishing a connection through the relay feeder 132, the digital location of the digital content management module storage device terminal 130 of the feeder device m facilitates the provision of a relay service. . . 21 200908655 27444twf.doc/n After the connection establishment is completed, in step S221, the digital content management module 122a of the terminal device 122 transmits an acknowledgement information outside the digital content providing server 112 and/or 114 to confirm the connection. line. In other words, the confirmation information is transmitted in a direct or indirect manner in accordance with the judgment of step S215. Thereafter, in step S223, the digital content providing server 112 and/or 114 will start to use the FTP or UDT to transfer the digital content/service after receiving the confirmation information number, that is, to transfer the digital content/service to the digital content management module. 122a.
