Can be displayed.

The membership fee management module 318 manages fees paid for a user who has subscribed as a paid member.

The operation of the IP multicast operating system according to the present invention configured as described above will be described in more detail with reference to the accompanying drawings.

First, the IP multicast support server 300 has a system in which an unspecified number of users can make an online connection through the network communication network 200, and an unspecified number of users access the IP through the network communication network 200. When the online connection is made to the multicast support server 300, the IP multicast support server 300 includes a paid membership and a free membership menu item to the user's terminal 430 using the network communication network 200. Provide an initial web page.

When the paid membership menu item is clicked by the user, the member management module 314 transmits the web page for the paid membership form to the user's terminal 430. Accordingly, when a user inputs user information and fee payment method through the web page for the paid membership form and clicks the registration button, the member management module 314 enters the user through the web page for the paid membership form. After supporting the information to be stored in the member information DB 312, the program check and transmission module 316 supports to download the paid content receiving program to the user terminal 430.

If the free membership menu item is clicked by the user, the member management module 314 transmits the web page for the free membership form to the user's terminal 430 similarly to the paid member. Accordingly, when a user inputs user information through the web page for the free member registration form and clicks a registration button, the member management module 314 stores the user information entered through the web page for the free membership form as a member information DB. After supporting to be stored at 312, the program check and transmission module 316 to support the user to download the free content receiving program to the terminal 430.

Of course, in the case of the free member does not automatically download the program, it is also possible to build a system so that the user himself can download through an area such as a bulletin board.

The user who downloaded the paid or free content receiving program receives the content transmitted through the satellite 100 through the satellite antenna 410 and the satellite receiving card 420 of the user terminal 400. Display on the screen so that the user can see it.

That is, the content front end portion transmitted through the satellite 100 includes the IP information and PORT information set by the content providing module 317, the IP information and PORT information is the paid or free content receiving program Also included.

Therefore, when there is data received through the satellite reception card 420, the content receiving program mounted on the terminal 430 first extracts IP information and PORT information from the data, Compare PORT information.

As a result of the comparison, the content is supplied and displayed on the screen of the terminal 430 only when it matches.

At this time, the IP information and PORT information embedded in the free content receiving program are disclosed so that anyone can know, and the IP information and PORT information built into the paid content receiving program can be known only by the user. Are emailed, or delivered offline.

Meanwhile, in the case of the paid member, a certain period is guaranteed for a certain fee, and when the guaranteed period is over, the paid member needs to re-register as a paid member and download the changed fee-based content receiving program again.

That is, as shown in FIG. 4, the program check and transmission module 316 reads a paid member registration date among user information registered in the member information DB 312 and checks the paid period of the paid member (S210). ), It is determined whether the paid period is over (S220). In this case, the paid period of the paid member is generally one month.

As a result of the determination of S220, when the paid period is over, the program check and transfer module 316 supports the member management module 314 to transmit the paid member re-subscription guide message to the terminal 430 of the paid member ( S230).

Then, the member management module 314 determines whether a paid member resubscription request signal is input from the user in response to the paid member resubscription guide message (S240).

As a result of the determination of step S240, when the user intends to re-register as a paid member, the paid content receiving program whose IP information and PORT information are changed is transmitted to the user terminal 430 through the network communication network 200 (S250).

If, as a result of the determination in step S240, the user does not want to re-register as a paid member, the information is deleted from the paid member area of the member information DB 312 (S260).

On the other hand, in order to provide advertising content provided to free members as well as paid members, or product contents to induce electronic commerce, a system must be established through the following process.

In other words, the operator of the IP multicast support server 300 to build a separate DB (311) by producing a variety of content, including video content to provide to a number of unspecified users, or to provide a website of the content {500 (1) to 500 (N)}.

Websites (500 (1) to 500 (N)) that are affiliated with the IP multicast support server 300 are upgraded when various information such as a product or a movie for advertising to a large number of users is upgraded. Each time, information upgraded to the IP multicast support server 300 is periodically provided.

In addition, the operator of the IP multicast support server 300, the web page produced by the IP multicast support server 300 itself for providing additional information about the content in addition to the various content provided to the satellite 100 The system is constructed so that it can be linked with affiliated websites {500 (1) to 500 (N)} that have or have provided the content.

For example, a process of constructing a system for directly producing and distributing the content and additional information will be described. For example, an operator of the IP multicast support server 300 may first advertise an advertisement for goods or movies to be provided to an unspecified number of users. After encoding the source into an ASF file, the contents to be inserted in the middle of the ASF file are planned, and the planned contents are generated into respective web pages by web designers. When the web page is generated, web programmers write a JavaScript for calling the web page in a main HTML file, and build a system to call the web page at a desired point in time of the ASF file.

Accordingly, as described above, according to the present invention, the contents supplied to the paid members and the free members can be classified and supplied, thereby achieving differentiation between the paid and free members, thereby enabling a wider content service to be performed through satellites. To provide.

In addition, the present invention by using a satellite to provide a content providing service, even if the transmission size, such as video content can be transmitted at a high speed, it is possible to prevent the damage caused by the transmission speed To provide.

In addition, since the present invention uses an artificial satellite, when a content receiving program is mounted on a user's terminal, the present invention provides an effect that content can be provided even in an area such as a mountainous region or an island where a wired communication network is not established.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified and changed within the scope of the invention without departing from the spirit and scope of the invention described in the claims below It will be appreciated.
