[43] The search server 260 statically analyzes the input search words, and manages the ranking list of the search word in the search- word DB 261. Also, the search- word DB 261 can manage the ranking of words (related search ranking list) related with the search word currently input.

[44] Accordingly, when receiving a request for the related search ranking list in relation with the information of the broadcasting program from the recommendation search- word server 240, the search server 260 provides the related search ranking list to the recommendation search- word server 240. Based on the related search ranking list, the recommendation search- word server 240 provides the recommendation search- word list related with the broadcasting program serviced to the IPTV terminal 220 by the IPTV server 230.

[45] FIG. 5 illustrates a detailed block diagram of the recommendation search- word server

240. As shown in FIG. 5, the recommendation search- word server 240 includes a recommendation search- word providing unit 510, a recommendation search- word DB 511, an advertising keyword providing unit 520, and a transaction managing DB 521.

[46] At this time, the recommendation search- word providing unit 510 manages the recommendation search- words related with the broadcasting program in the recommendation search- word DB 511. The advertising keyword providing unit 520 registers and manages the keyword including the recommendation search- word purchased by the advertiser as the advertising keyword included in the service of the broadcasting program in the transaction managing DB 521.

[47] For example, the broadcasting program serviced to the IPTV terminal 220 by the

IPTV server 230 is to be corresponded to program information. At this time, the broadcasting program serviced by the IPTV server 230 may be the download-type program such as movie or music; or the broadcasting program whose televising time is preset in a preset time slot by cable TV broadcasting, DMB broadcasting, or domestic/ foreign general TV broadcasting such as MBC, SBC, KBS, YTN, CNN, BBC, and etc.

[48] Also, the download-type program and the program whose televising time is preset may include the advertisement therein. In this case, the advertisement included in the program may be the broadcasting program mentioned in the present invention.

[49] The program information included in the broadcasting program relates with the broadcasting contents of the currently serviced program, that is, the title of the broadcasting program, or the keyword of the contents about the serviced broadcasting program. For example, as shown in FIG. 3, when servicing the broadcasting program 'Jumong', the program information may include 'Jumong' corresponding to the title of the broadcasting program; or the content keyword of the broadcasting program such as 'Koguryo', 'Historical drama', or 'SONG Il Kook'.

[50] To manage the recommendation search-words, the recommendation search- word providing unit 510 can request the related search ranking list about the program information of the broadcasting program from the search server 260. Accordingly, the search server 260 performs the search for the title or content keyword of the broadcasting program included in the program information from the search-word DB 261; extracts the related search ranking list in relation with the program information; and provides the extracted list to the recommendation search- word providing unit 510.

[51] The recommendation search- word providing unit 510 receives the related search ranking list in relation with the program information. Then, the recommendation search- word providing unit 510 stores the received ranking list in the recommendation search- word DB 511, wherein the stored ranking list serves as the recommendation search-word for the corresponding broadcasting program. At this time, the recommendation search- word providing unit 510 may store the entire ranking list, or may store only limited number, for example, five or ten, among the entire search words included in the ranking list.

[52] When the IPTV server 230 services the corresponding broadcasting program to the

IPTV terminal 220, the recommendation search-word corresponding to the managed broadcasting program is provided to the IPTV server 230, and is then shown on the IPTV terminal 220. For example, as shown in FIG. 3, in the case of broadcasting program 'Jumong', the IPTV terminal 220 may be provided with the recommendation search-words related with the broadcasting program 'Jumong', for example, 'SONG Il Kook', 'Jumong Game', 'Jumong 4', Ηaeshin', 'AHN Yong Jun', 'CHUNG Ho Bin', 'SONG Ji Hyo', and 'DAE Jo Young'as well as 'Jumong'.

[53] According to another example, in the case of download-type program such as movie, the recommendation search- word list can be managed and provided. Also, if the advertisement is included in the download-type program or the regular TV broadcasting program, the title of the corresponding advertisement or the recommendation search- word list related with the content keyword can be managed and provided. For example, if the advertisement for washing machine 'TROMM' is inserted into the broadcasting program, the recommendation search-word list may be provided during servicing the corresponding advertisement, for example, 'TROMM', 'TROMM LG', 'TROMM SERVICE', 'TROMM WASHING MACHINE', 'WASHING SERVICE', and 'TROMM AUCTION'.

[54] The recommendation search- word managed by the recommendation search- word DB

511 is sold by the advertising keyword providing unit 520 to the advertiser. That is, the advertiser may access to a website operated by the recommendation search- word server 240, to purchase the recommendation search-word via on-line. For example, the advertising server 250 operated by the advertiser can send a request for the purchase of the recommendation search-word to the advertising keyword providing unit 520 via on-line. In response to the request of the advertising server 250, the advertising keyword providing unit 520 can provide the recommendation search- word list to the advertising server 250. Especially, the advertising keyword providing unit 520 can provide the advertiser with the recommendation search-word list about the information (the title or content keyword of the broadcasting program) of the broadcasting programs serviced by the IPTV server 230.

[55] The advertiser can request the acceptance from the advertising server 250 by selecting the entire or partial portion from the received list through the advertising server 250. When the process for the authentication and payment of service is finished, the advertising keyword providing unit 520 accepts the request made by the advertiser. Accordingly, the advertising keyword providing unit 520 can register and manage the entire or partial portion of the recommendation search- word list in the transaction managing DB 521, wherein the entire or partial portion of the recommendation search- word list serves as the advertising keyword for the corresponding purchasing request.

[56] The managed advertising keyword is transmitted to the IPTV server 230 through the advertising server 250 when the IPTV server 250 provides the corresponding broadcasting program to the IPTV terminal 220, whereby the advertising keyword is shown on the IPTV terminal 220. For example, if the advertiser selects 'Jumong' from the recommendation search- word list, and registers 'Jumong' as the advertising keyword, 'Jumong' as well as the recommendation search- word list is shown as the advertising keyword on televising the corresponding broadcasting program.

[57] At this time, if the advertiser selects and purchases 'Jumong' from the recommendation search- word list via on-line, the related keywords such as 'Jumong toys' and 'Jumong accessories' may be additionally registered and managed in the transaction managing DB 521, as shown in FIG. 3. This enables the viewer to briefly know about the merchandise or service advertised by the advertiser.

[58] When managing the recommendation search-word and advertising keyword, for example, servicing the predetermined broadcasting program to the IPTV terminal 220 by the IPTV server 230, the program information about the corresponding broadcasting program is generated, and the generated program information is transmitted to the recommendation search- word providing unit 510 and the advertising keyword providing unit 520.

[59] Accordingly, the recommendation search- word providing unit 510 can transmit the recommendation search- word list about the corresponding broadcasting program to the IPTV server 230. At this time, the IPTV server 230 may service the corresponding broadcasting program with the recommendation search-word list interest thereinto, whereby the recommendation search-word list can be shown on the IPTV terminal 220, as shown in FIG. 3.

[60] The advertising keyword providing unit 520 receives the program information about the corresponding broadcasting program. Then, the advertising keyword providing unit 520 searches the transaction managing DB 521 for the corresponding advertising keyword, and transmits the corresponding advertising keyword to the advertising server 250. Accordingly, the advertising server 250 transmits the corresponding advertising keyword to the IPTV server 230. The IPTV server 230 services the corresponding broadcasting program with the advertising keyword, as shown in FIG. 3. Also, when the advertising keyword shown on the IPTV terminal 220 is selected, the IPTV server 230 can relay the contents of the corresponding advertisement provided from the advertising server 250 to the IPTV terminal 220, as shown in FIG. 4.

[61] FIG. 6 illustrates one exemplary block diagram of the advertising server of FIG. 2.

Referring to FIG. 6, the advertising server 240 includes an advertising keyword transmitting unit 610, an advertisement providing unit 620, an advertising content DB 621, a purchase managing unit 630, and a purchase keyword DB 631.

[62] As explained above, the purchase managing unit 630 can send a request for the purchase of advertising keyword to the advertising keyword providing unit 520. According to the request for the purchase of advertising keyword, the purchase managing unit 630 can receive the recommendation search- word list about the program information (the title or content keyword of the broadcasting program) of the broadcasting programs serviced by the IPTV server 230 from the advertising keyword providing unit 520. When the advertiser selects the entire or partial portion from the recommendation search- word list, the purchase managing unit 630 stores the advertising keyword in the purchase keyword DB 631, and manages the advertising keyword stored in the purchase keyword DB 631, wherein the advertising keyword may be the search word (for example, 'Jumong' shown in FIG. 3) corresponding to the broadcasting program in the purchase keyword DB 631, or the keyword ('Jumong toys', 'Jumong accessories', and etc.) including the search word.

[63] In order to make the viewer briefly know about the merchandise or service advertised by the advertiser, the advertising keyword such as the keyword with the related words as well as the purchased search word is transmitted to the advertising keyword providing unit 520. Also, the purchased search word or the keyword related with the purchased search word, which serves as the advertising keyword, is managed in the purchase keyword DB 631.

[64] When the IPTV server 230 provides the corresponding broadcasting program to at least one IPTV terminal 220 after completing the registration of the advertising keyword through the advertising keyword providing unit 520, the advertising keyword providing unit 520 transmits the corresponding advertising keyword to the advertising keyword transmitting unit 610 according to the program information of the corresponding broadcasting program. Accordingly, as shown in FIG. 3, the advertising keyword is inserted into the broadcasting program, whereby the broadcasting program with the advertising keyword inserted thereinto is shown on the IPTV terminal.

[65] During watching the broadcasting program through the IPTV terminal 220, as shown in FIG. 3, if the viewer is interested in the advertising keyword shown on the IPTV terminal 220, the viewer can select the shown advertising keyword so as to get the information about the merchandise or service advertised.

[66] The information about the advertising keyword selected by the viewer is transmitted to the advertisement providing unit 620 through the IPTV server 230. Accordingly, the advertisement providing unit 620 checks whether the advertising keyword is the purchased keyword with reference to the purchase keyword DB 631. After completing the check, the advertising contents about the corresponding advertising keyword is searched in the advertising content DB 621, and is then provided to the IPTV terminal 220.

[67] For example, if the viewer selects 'Jumong accessories' from the list shown on the screen of IPTV terminal in FIG. 3, the detailed contents about the advertisement may be provided as shown in FIG. 4. That is, the advertiser may be a businessman who sells toys or accessories. As shown in FIG. 4, the advertiser may sell various kinds of merchandises related with 'Jumong' for example, necklaces with pictures of 'Jumong', and other actors or actresses, mobile-phone strings, or key-holders. Thus, if the viewer wants to purchase the advertised merchandise after checking the detailed information, the viewer can purchase the advertised merchandise through the contact with the advertiser.

[68] As shown in FIG. 4, when the viewer selects an appointment tag for purchasing the advertised merchandise, a purchasing- appointment screen is displayed so as to keep a record about the item to be purchased, for example, the number of items to be purchased, the delivery address, and the contact information. The purchasing-appointment screen may be managed in the advertising server 250. Especially, for association with the advertising contents, the purchasing- appointment screen may be managed in the advertisement providing unit 620. Also, the purchasing-appointment scheduling may be managed in the advertisement content DB 621 or another DB.

[69] An operation of the advertisement providing system 200 according to one embodiment of the present invention will be described with reference to FIG. 7.

[70] The broadcasting program serviced to the IPTV terminal 220 by the IPTV server 230 is provided with the program information. At this time, the broadcasting program served by the IPTV server 230 may include the download-type program such as movie or music; or the broadcasting program whose televising time is preset in a predetermined time slot by cable TV broadcasting or DMB broadcasting, for example, the general broadcasting program by domestic or foreign general TV broadcasting such as MBC, SBC, KBS, YTN, CNN, BBC, and etc. Furthermore, the advertising program included in the download-type program or the program televised in the predetermined time slot can be included.

[71] For the use of list of the related search ranking list managed in the search server 260, the recommendation search- word providing unit 510 of the recommendation search- word server 240 sends the request for the related search ranking about the program information of the broadcasting programs to the search server 260, and also receives the related search ranking list (S71).

[72] The search server 260 searches the search word DB 261 for the title (as explained above, 'Jumong' corresponding to the title of historical drama, or 'TROMM washing machine' corresponding to the title of advertising program) of the broadcasting program included in the corresponding program information or content keyword (as explained above, 'Koguryo', 'Historical drama', 'SONG Il Kook', and etc. during the p eriod of servicing the broadcasting program 'Jumong', or 'TROMM' 'Washing machine', 'LG', and etc. during the period of servicing the advertising program 'TROMM washing machine'); extracts the related search ranking list about the program information as shown in FIG. 3; and provides the extracted ranking list to the recommendation search- word providing unit 510.

[73] The recommendation search- word providing unit 510 stores and manages the related search ranking list received from the search server 260 in the recommendation search- word DB 511 (S72), wherein the stored ranking list of the search words may serve as the recommendation search- word of the corresponding broadcasting program. At this time, the recommendation search- word providing unit 510 may store the entire ranking list in the recommendation search- word DB 511, or may store only limited number, for example, five or ten, among the entire search words of the ranking list in the recommendation search- word DB 511.

[74] The recommendation search-word managed in the recommendation search- word DB

511 may be sold to the advertiser by the advertising keyword providing unit 520. That is, the advertiser may purchase the recommendation search- word through the access to the website operated by the recommendation search- word server 240. For example, the purchase managing unit 630 of the advertising server 250 operated by the advertiser can send the request for the purchase of recommendation search- word to the advertising keyword providing unit 520 via on-line. In response to the request of recommendation search- word, the advertising keyword providing unit 520 provides the rec- ommendation search-word list to the advertising server 250 (S73). Especially, the recommendation search-word list related with the program information (the title or content keyword of the corresponding broadcasting program) about the broadcasting programs serviced by the IPTV server 230 may be provided.

[75] Then, the advertiser can request the acceptance from the advertising server 250 by selecting the entire or partial portion from the received list through the advertising server 250. When the process for the authentication and payment of service is finished, the advertising keyword providing unit 520 accepts the request made by the advertiser. Accordingly, the advertising keyword providing unit 520 registers and manages the entire or partial portion of the recommendation search- word list in the transaction managing DB 521 (S74), wherein the entire or partial portion of the recommendation search-word list may serve as the advertising keyword in response to the corresponding advertising server 250 or purchasing request. When the advertiser selects the particular keyword from the recommendation search- word list via on-line, for example, 'Jumong', the keyword including the related search words, for example, the keyword including 'Jumong', that is, Jumong toys', or 'Jumong accessories' shown in FIG. 3 may be registered and managed in the transaction managing DB 521 and purchase keyword DB 631. This enables the view to briefly know about the merchandise or service through the glance of advertising keyword.

[76] During the managing the recommendation search-word and advertising keyword, for example, servicing the predetermined broadcasting program to the IPTV terminal 220 by the IPTV server 230, the program information about the corresponding broadcasting program is generated (S75). Then, the program information is transmitted to the recommendation search- word providing unit 510 and the advertising keyword providing unit 520 (S76). Accordingly, the recommendation search- word providing unit 510 transmits the recommendation search-word list for the corresponding broadcasting program to the IPTV server 230 (S77). At this time, the IPTV server 230 inserts the recommendation search- word list into the corresponding broadcasting program, whereby the recommendation search-word list is shown on the IPTV terminal 220, as shown in FIG. 3 (S78).
