     DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS 
     Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. 
       FIG. 1  is a view illustrating a contents search service system according to an embodiment of the present invention. 
     As illustrated in  FIG. 1 , the contents search service system according to the present invention includes contents providing servers  300 A to  300 N, each for including contents and managing hits information with respect to reproducing period for the contents, a terminal device  100  for requesting a search for certain content, and a contents search service providing server  200  for generating and managing total hits information with respect to reproducing period based on the hits information with respect to reproducing period collected by interworking with the at least one contents providing servers  300 A to  300 N, searching for the certain content requested by the terminal device  100  from the at least one contents providing server  300 A to  300 N through clustering, and providing search result and the total hits information with respect to reproducing period for the certain content to the terminal device  100 . 
     The terminal device  100  is a reproducing apparatus for reproducing contents obtained by various methods. The terminal device  100  may include various apparatuses such as a mobile terminal, a personal digital assistant (PDA), a notebook, a personal computer (PC), and an Internet TV that may reproduce video contents such as broadcasting contents, video on demand (VOD) contents, or user created contents (UCC). 
     The terminal device  100  accesses the contents search service providing server  200  and provides a search word (for example, XX drama episode 3) input by a user to the contents search service providing server  200  to request the contents corresponding to the search word (for example, XX drama episode 3). 
     Each of the contents providing servers  300 A to  300 B manages hits information with respect to each of reproducing periods of contents included in the contents providing server. 
     The above will be described in detail with reference to the contents providing server  300 A among the contents providing servers  300 A to  300 N. The contents providing server A  300 A stores/possesses various contents registered by various users or contents providers and continuously monitors which content (for example, video content  1 ) is selected and reproduced by a predetermined user with respect to each of the various contents possessed by the contents providing server A  300 A and which reproducing period (for example, reproducing periods  3  and  4 ) is reproduced among the previously set reproducing periods (for example, reproducing periods  1 ,  2 ,  3 ,  4 , and  5 ) of a corresponding content (for example, the video content  1 ) when the corresponding content is selected and reproduced to generate and manage hits information with respect to each of reproducing periods for each of the contents. 
     The contents providing server A  300 A may generate and manage content information including at least one of meta information of the corresponding content with respect to each of the possessed contents, additional comment information on each of the previously set reproducing periods, and information on the title of each of the reproducing periods as well as hits information with respect to each of reproducing periods of each of contents included in the contents providing server A  300 A. 
     That is, the contents providing server A  300 A may manage meta information (for example, content identification information, content title information, total reproducing time information, information on reproducing time in each of the reproducing periods that represents the start of reproducing and the end of reproducing, genre information, theme information, character information, and story information) that is registered with respect to each of the various contents possessed by the contents providing server A  300 A. In addition, the contents providing server A  300 A may collect and store the additional comment information (for example, comments, reviews, and questions) and information on the title of a reproducing period (for example, the title of a reproducing period and the story of a reproducing period) that are registered in synchronization with a predetermined reproducing period (for example, reproducing period  2 ) with respect to the content (for example, the video content  1 ) selected and reproduced by a predetermined user among the contents possessed by the contents providing server A  300 A or with respect to the content (for example, the video content  1 ) selected by a contents provider. 
     The contents providing server A  300 A may manage the content information including the meta information of the corresponding content, information on additional comments in each of the reproducing periods, and information on the title of each of the reproducing periods with respect to each of the contents possessed by the contents providing server A  300 A. 
     Each of the contents providing servers  300 A to  300 N may provide hits information with respect to each of reproducing periods of contents included in the contents providing server and information on each of the contents possessed by the contents providing server to the contents search service providing server  200  through inter-working with the contents search service providing server  200 . 
     The contents search service providing server  200  collects at least one hits information with respect to each of reproducing periods for each of the contents possessed by each of the contents providing servers  300 A to  300 N through inter-working with each of the contents providing servers  300 A to  300 N in accordance with the generation of a periodic or predetermined event (for example, request performed by the terminal device  100  to search for a content) and generates and manages total hits information with respect to each of reproducing periods for the contents providing servers  300 A to  300 N based on the at least one hits information with respect to each of reproducing periods for each of the contents possessed by each of the contents providing servers  300 A to  300 N. 
     The contents search service providing server  200  searches for the content requested to be searched for through clustering in accordance with the contents search service providing server  200  inter-working with each of the contents providing servers  300 A to  300 N when it is requested by the terminal device  100  to search for the content and provides a search result and hits information with respect to each of reproducing periods of searched content to the terminal device  100 . 
     Hereinafter, the contents search service providing server  200  according to the present invention will be described in detail with reference to  FIG. 2 . 
     As illustrated in  FIG. 2 , the contents search service providing server  200  according to the present invention includes a hit number information managing unit  210  for generating and managing total hits information with respect to each of reproducing periods for the contents based on at least one hits information with respect to each of reproducing periods for each of the contents that is collected through inter-working with each of the contents providing servers  300 A to  300 N and a search result providing unit  240  for, when it is requested by the external terminal device  100  to search for a predetermined content, searching for the content requested to be searched for through clustering in accordance with the search result providing unit  240  inter-working with each of the contents providing servers  300 A to  300 N to provide a search result and the total hits information with respect to each of reproducing periods for the corresponding content to the terminal device  100 . 
     The hit number information managing unit  210  collects the at least one hits information with respect to each of reproducing periods for each of the contents possessed by each of the contents providing servers  300 A to  300 N through inter-working with each of the contents providing servers  300 A to  300 N in accordance with the generation of the periodic or predetermined event (for example, the request performed by the terminal device  100  to search for a content) and generates and manages total hits information with respect to each of reproducing periods for each of the contents based on the at least one hits information with respect to each of reproducing periods for the contents possessed by each of the contents providing servers  300 A to  300 N. 
     That is, the hit number information managing unit  210  collects hits information with respect to each of reproducing periods of the contents possessed by each of the contents providing servers  300 A to  300 N from the contents providing servers  300 A to  300 N. 
     At this time, when the contents providing server A  300 A and the contents providing server N  300 N possess the same content (for example, the video content  1 ), the hit number information managing unit  210  collects hits information A for the corresponding content (for example, the video content  1 ) from the contents providing server A  300 A and collects hits information N for the corresponding content (for example, the video content  1 ) from the contents providing server N  300 N. 
     The hit number information managing unit  210  may collect only one hits information with respect to each of reproducing periods for certain content (for example, video content  3 ) and may collect various hits information with respect to each of reproducing periods (for example, hits information A, B, and N) for certain content (for example, the video content  1 ) with respect to each of the various contents possessed by each of the contents providing servers  300 A to  300 N. 
     The hit number information managing unit  210  generates and manages total hits information with respect to each of reproducing periods for the contents based on the at least one hits information with respect to each of reproducing periods that is collected by the hit number information managing unit  210  inter-working with each of the contents providing servers  300 A to  300 N as described above. 
     For example, when the only one hits information with respect to each of reproducing periods for a predetermined content (for example, the video content  3 ) is collected, the hit number information managing unit  210  may generate total hits information with respect to each of reproducing periods for the content (for example, the video content  3 ) by applying the only one hits information with respect to each of reproducing periods for the content (for example, the video content  3 ) as total hits information with respect to each of reproducing periods for the content (for example, the video content  3 ). In addition, when various hits information with respect to each of reproducing periods (for example, the hit number information items A, G, and N by each reproducing period) for a predetermined content (for example, the video content  1 ) are collected, the hit number information managing unit  210  may generate total hits information with respect to each of reproducing periods for the content (for example, the video content  1 ) by summing up hits information with respect to reproducing period for the content (for example, the video content  1 ) based on the various hits information with respect to each of reproducing periods (for example, the hit number information items A, G, and N by each reproducing period) for the content (for example, the video content  1 ). 
     It is assumed that hits information A for the content (for example, the video content  1 ) indicates that the number of hits is 4,000 in reproducing period  1 , the number of hits is 2,000 in reproducing period  2 , the number of hits is 1,000 in reproducing period  3 , the number of hits is 5,000 in reproducing period  4 , and the number of hits is 5,000 in reproducing period  5   
     Similarly, it is assumed that hits information B with respect to reproducing period for the content (for example, the video content  1 ) indicates that the number of hits is 40 in the reproducing period  1 , the number of hits is 20 in the reproducing period  2 , the number of hits is 50 in the reproducing period  3 , the number of hits is 60 in the reproducing period  4 , and the number of hits is 60 in the reproducing period  5 , and it is assumed that hits information N with respect to reproducing period for the content (for example, the video content  1 ) indicates that the number of hits is 60 in the reproducing period  1 , the number of hits is 80 in the reproducing period  2 , the number of hits is 50 in the reproducing period  3 , the number of hits is 140 in the reproducing period  4 , and the number of hits is 240 in the reproducing period  5 . 
     The hit number information managing unit  210  may sum up hits information with respect to each of reproducing periods to generate total hits information with respect to each of reproducing periods (the number of hits is 4,100 in the reproducing period  1 , the number of hits is 2,100 in the reproducing period  2 , the number of hits is 1,100 in the reproducing period  3 , the number of hits is 5,200 in the reproducing period  4 , and the number of hits is 5,300 in the reproducing period  5 ) for the corresponding content (for example, the video content  1 ). 
     At this time, when the number of users of a specific contents providing server (for example, the contents providing server A  300 A) is remarkably larger than the number of users of the other servers so that the number of hits that the content has in the contents providing server A  300 A is particularly high, it may be necessary to perform normalization in generating total hits information with respect to each of reproducing periods based on the at least one hits information with respect to each of reproducing periods that is collected from each of the contents providing servers  300 A to  300 N. 
     In generating total hits information with respect to each of reproducing periods based on the at least one hits information with respect to each of reproducing periods that is collected through inter-working with each of the contents providing servers  300 A to  300 N as described above, the hit number information managing unit  210  normalizes the at least one hits information with respect to each of reproducing periods and generates total hits information with respect to each of reproducing periods for a corresponding content by summing up hits information with respect to reproducing period based on the normalized at least one hits information with respect to each of reproducing periods. 
     For example, with respect to the at least one hits information with respect to each of reproducing periods (for example, the hits information items A, B, and N) for a predetermined content (for example, the video content  1 ), the hit number information managing unit  210  recognizes the entire hits, the number of reproducing periods, and the average number of hits from corresponding hits information with respect to each of reproducing periods of the content (for example, the video content  1 ) and normalizes the corresponding hits information based on the recognized average number of hits. 
     That is, when it is assumed that the hits information A with respect to each of reproducing periods for the content (for example, the video content  1 ) indicates that the number of hits is 4,000 in reproducing period  1 , the number of hits is 2,000 in reproducing period  2 , the number of hits is 1,000 in reproducing period  3 , the number of hits is 5,000 in reproducing period  4 , and the number of hits is 5,000 in reproducing period  5 , the hit number information managing unit  210  may recognize that the entire hits are 17,000 (4,000+2,000+1,000+5,000+5,000), that the number of reproducing periods is 5, and that the average number of hits is 3,400 (17,000/5) from the hits information A for the content (for example, the video content  1 ) and may draw hits information A (the number of hits is 1.2 in the reproducing period  1 , the number of hits is 0.6 in the reproducing period  2 , the number of hits is 0.3 in the reproducing period  3 , the number of hits is 1.5 in the reproducing period  4 , and the number of hits is 1.5 in the reproducing period  5 ) (for example, rounding off the numbers to two decimal places) for the content (for example, the video content  1 ) normalized by dividing the corresponding hits information A for the content (for example, the video content  1 ) by the recognized average number of hits (3,400). In such a method, hits information B and N may be normalized. 
     With respect to the normalized information (for example, hits information A, B, and N) for the corresponding content (for example, the video content  1 ), the hit number information managing unit  210  may generate total hits information with respect to each of reproducing periods (the number of hits is X 1  in the reproducing period  1 , the number of hits is X 2  in the reproducing period  2 , the number of hits is X 3  in the reproducing period  3 , the number of hits is X 4  in the reproducing period  4 , and the number of hits is X 5  in the reproducing period  5 ) for the corresponding content (for example, the video content  1 ) by summing up hits information with respect to reproducing period. 
     When it is requested by the terminal device  100  to search for the content corresponding to a predetermined search word (for example, XX drama episode 3), the search result providing unit  240  searches the content (for example, the XX drama episode 3—the video content  1 ) requested to be searched for through clustering in accordance with the search result providing unit  240  inter-working with each of the contents providing servers  300 A to  300 N and provides the search result and total hits information with respect to each of reproducing periods for the corresponding content (for example, the XX drama episode 3—the video content  1 ) to the terminal device  100 . Here, since a conventional clustering method may be adopted as a method of searching for content on the Web through clustering, a detailed description thereof will be omitted. 
     That is, the search result providing unit  240  provides a search result, including at least one of contents providing server related information of a corresponding contents providing server that provides/possesses the content (for example, the XX drama episode 3—the video content  1 ) searched for in accordance with the search request of the terminal device  100  and contents related information of corresponding contents published in a corresponding contents providing server, and total hits information with respect to each of reproducing periods for the corresponding content (for example, the XX drama episode 3—the video content  1 ), which is managed by the hit number information managing unit  210 , to the terminal device  100 , so that the terminal device  100  displays the search result and displays a popularity indication bar by which it is possible to identify the total number of hits of the corresponding content (for example, the XX drama episode 3—the video content  1 ) with respect to each of the reproducing periods. 
     When the contents providing server A  300 A and the contents providing server N  300 N provide/possess the searched content (for example, the XX drama episode 3—the video content  1 ), the contents providing server related information may include service name information, access address information, and image information representing a corresponding server of the contents providing server A  300 A and the contents providing server N  300 N. 
     The contents related information may include storage position information, content identification information, content title information, and thumbnail information of the corresponding content (for example, the XX drama episode 3—the video content  1 ) in a corresponding contents providing server (for example, the contents providing servers  300 A and  300 N). 
     When the search result and total hits information with respect to each of reproducing periods are provided from the contents search service providing server and, in particular, the search result providing unit  240  in accordance with the search request, the terminal device  100  displays the contents providing server which provides and possesses the corresponding content (for example, the XX drama episode 3—the video content  1 ) in accordance with the search result, and displays the popularity indication bar, by which it is possible to identify the total number of hits that the corresponding content (for example, the XX drama episode 3—the video content  1 ) with respect to each of the reproducing periods, in accordance with the total hits information with respect to each of reproducing periods for the corresponding content (for example, the XX drama episode 3—the video content  1 ). At this time, in the popularity indication bar, different display colors are assigned in accordance with the range of the previously set total number of hits so that each of the reproducing periods has a display color in accordance with the range to which the corresponding total number of hits belongs. Here, the display color assigned in accordance with the range of the total number of hits is darker as the total number of hits is larger, that is, the popularity is higher and is lighter as the total number of hits is smaller, that is, the popularity is lower. 
     Therefore, the user of the terminal device  100  recognizes the contents providing servers that provide and possess the content (for example, the XX drama episode 3—the video content  1 ) requested to be searched for and, in particular, may check the popularity of the corresponding content (for example, the XX drama episode 3—the video content  1 ) on reproducing period basis at a look. 
     On the other hand, the contents search service providing server  200  according to the present invention may further include a period content information managing unit  220 . 
     The period content information managing unit  220  generates and manages information on each of the contents with respect to each of the reproducing periods based on at least one information item on each of the contents including at least one of meta information of each of the contents that is collected through inter-working with each of the contents providing servers  300 A to  300 N, additional comment information, and information on the title with respect to each of the reproducing periods. 
     That is, the period content information managing unit  220  collects at least one information item on each of the contents possessed by each of the contents providing servers  300 A to  300 N through inter-working with each of the contents providing servers  300 A to  300 N in accordance with the generation of a periodic or predetermined event (for example, the request performed by the terminal device  100  to search for a content) and generates and manages the information on each of the contents with respect to each of the reproducing periods. 
     For example, the period content information managing unit  220  collects information on each of the contents possessed by each of the contents providing servers  300 A to  300 N from each of the contents providing servers  300 A to  300 N. Here, the content information includes meta information (for example, content identification information, content title information, total reproducing time information, information on reproducing time with respect to each of the reproducing periods that represents the start of reproducing and the end of reproducing, genre information, theme information, character information, and story information) of the corresponding content (for example, the video content  1 ) and additional comment information (for example, comments, reviews, and questions) with respect to each of the reproducing periods of the corresponding content (for example, the video content  1 ), and information on the title of each of the reproducing periods (for example, the title of a reproducing period and the story of a reproducing period) as described above when the contents providing servers  300 A to  300 N are described. 
     At this time, when the contents providing server A  300 A and the contents providing server N  300 N possess the same content (for example, the video content  1 ), the period content information managing unit  220  collects information A on the corresponding content (for example, the video content  1 ) from the contents providing server A  300 A and collects information N on the corresponding content (for example, the video content  1 ) from the contents providing server N  300 N. 
     The period content information managing unit  220  may collect the only one information item on a certain content (for the video content  3 ) and may collect various information items (for example, the content information items A, B, and N) on a certain content (for example, the video content  1 ) with respect to each of the various contents possessed by each of the contents providing servers  300 A to  300 N. 
     The period contents information managing unit  220  generates and manages the information on each of the contents with respect to each of the reproducing periods based on the information on each of the contents that is collected through inter-working with each of the contents providing servers  300 A to  300 N as described above. 
     For example, the period content information managing unit  220  may generate the information on each of the contents with respect to each of the reproducing periods including at least one of the title, the additional comments (for example, comments, reviews, and questions), and the story of a corresponding reproducing period (for example, the reproducing period  1 ) with respect to the reproducing periods (for example, the reproducing periods  1 ,  2 ,  3 ,  4 , and  5 ) based on the information (for example, the meta information, the additional comment information with respect to each of the reproducing periods, and the information on the title of each of the reproducing periods) on the corresponding content (for example, the video content  3 ) when the only one content information item on a predetermined content (for example, the video content  3 ) is collected. In addition, the period content information managing unit  220  may generate the information on each of the contents with respect to each of the reproducing periods including at least one of the title, the additional comments (for example, comments, reviews, and questions), and the story of a corresponding reproducing period (for example, the reproducing period  1 ) with respect to the reproducing periods (for example, the reproducing periods  1 ,  2 ,  3 ,  4 , and  5 ) based on the various content information items (for example, the content information items A, B, and N) when the various information items (for example, the content information items A, B, and N) on a predetermined content (for example, the video content  1 ) are collected. 
     On the other hand, as described above, a specific reproducing period (for example, the reproducing period  2 ) on the popularity indication bar may be indicated by the terminal device  100  which displays the search result and the popularity indication bar, by which it is possible to identify the total number of hits for the content (for example, the XX drama episode 3—the video content  1 ) with respect to each of the reproducing periods, based on the search result and the total hits information with respect to each of reproducing periods for the content (for example, the XX drama episode 3—the video content  1 ), which are provided in accordance with a search request for the content (for example, the XX drama episode 3—the video content  1 ). 
     When the specific reproducing period (for example, the reproducing period  2 ) on the popularity indication bar is indicated by the terminal device  100  displaying the popularity indication bar as described above, the search result providing unit  240  provides information on the content (for example, the video content  1 ) in the indicated specific reproducing period (for example, the reproducing period  2 ) from the information on the corresponding content (for example, the video content  1 ) with respect to each of the reproducing periods of the period content information managing unit  220  to the terminal device  100  so that the information on the content (for example, the video content  1 ) in the reproducing period (for example, the reproducing period  2 ) including at least one of the title, the additional comments, and the story of the corresponding reproducing period (for example, the reproducing period  2 ) is displayed. 
     Therefore, in the state where the terminal device  100  displays the contents providing server which to provides/possesses the corresponding content (for example, the XX drama episode 3—the video content  1 ) in accordance with the search result and displays the popularity indication bar by which it is possible to identify the total number of hits of the corresponding content (for example, the XX drama episode 3—the video content  1 ) in each of the reproducing periods, that is, the popularity of the content (for example, the XX drama episode 3—the video content  1 ) in each of the reproducing periods in accordance with total hits information with respect to each of reproducing periods for the content (for example, the XX drama episode 3—the video content  1 ), the user may indicate a specific reproducing period to conveniently identify the title of the specific reproducing period, the brief story of the specific reproducing period, and the additional comments of the other users in the specific reproducing period. 
     On the other hand, when the search result and the total hits information with respect to each of reproducing periods for the corresponding content (for example, the video content  1 ) are provided to the terminal device  100  in accordance with the request performed by the terminal device  100  to search for the content (for example, the XX drama episode 3—the video content  1 ), the search result providing unit  240  further provides the information on the corresponding content (for example, the video content  1 ) in each of the reproducing periods so that, when the terminal device  100  displays the search result and the popularity indication bar by which it is possible to identify the total number of hits of the content (for example, the video content  1 ) in each of the reproducing periods, the terminal device  100  may further display the information on the content (for example, the video content  1 ) with respect to each of the reproducing periods. 
     That is, when the search result providing unit  240  provides the search result and the total hits information with respect to each of reproducing periods for the corresponding content (for example, the video content  1 ) that are described above to the terminal device  100  in accordance with the request performed by the terminal device  100  to search for the content (for example, the XX drama episode 3—the video content  1 ), the search result providing unit  240  may further provide the information on the corresponding content (for example, the video content  1 ) in with respect to each of the reproducing periods that is managed by the period content information managing unit  220 . 
     When the search result, the total hits information with respect to each of reproducing periods for the content (for example, the video content  1 ), and the information on the content (for example, the video content  1 ) in each of the reproducing periods are provided from the contents search service providing server and, in particular, the search result providing unit  240  in accordance with the search request, the terminal device  100  displays the contents providing server which provides and possesses the corresponding content (for example, the XX drama episode 3—the video content  1 ) in accordance with the search result, and displays the popularity indication bar, by which it is possible to identify the total number of hits of the corresponding content (for example, the XX drama episode 3—the video content  1 ) with respect to each of the reproducing periods, in accordance with the total hits information with respect to each of reproducing periods for the corresponding content (for example, the XX drama episode 3—the video content  1 ). Also, the terminal device  100  may display period contents information, which includes at least one of a period title, additional comments, and story of each of the reproducing periods of the corresponding content (for example, the XX drama episode 3—the video content  1 ) in accordance with the period contents information of each of the reproducing periods. 
     Therefore, the user of the terminal device  100  recognizes the contents providing servers that provide/possess the content (for example, the XX drama episode 3—the video content  1 ) requested to be searched for and, in particular, may conveniently check the popularity of the corresponding content (for example, the XX drama episode 3—the video content  1 ) in each of the reproducing periods, the title of each of the reproducing periods, the brief story of each of the reproducing period, and the additional comments of the other users in the corresponding reproducing period at a look. 
     Here, a progress bar representing the reproducing position of content may be commonly used as the above described popularity indication bar. 
     On the other hand, the contents search service providing server  200  according to the present invention further includes a contents storage unit  230  to store and manage the contents that may be provided by the contents search service providing server  200  in the contents storage unit  230  and the contents storage unit  230  or an additional functional unit (not shown) may generate and manage hits information with respect to each of reproducing periods of contents included in the contents storage unit  230  like each of the above described contents providing servers  300 A to  300 N. 
     In this case, when the hit number information managing unit  210  generates total hits information with respect to each of reproducing periods for each of the contents through inter-working with each of the contents providing servers  300 A to  300 N as described above, the hit number information managing unit  210  generates hits information with respect to each of reproducing periods based on hits information with respect to each of reproducing periods that is managed by the contents search service providing server  200  as well as hits information with respect to each of reproducing periods that is collected from each of the contents providing servers  300 A to  300 N. 
     The contents search service providing server  200  according to the present invention may further include a contents providing unit  250 . 
     When a specific reproducing period (for example, the reproducing period  2 ) is selected to be reproduced with respect to the content (for example, the video content  1 ) published in a predetermined contents providing server (for example, the contents providing server A  300 A) based on the search result displayed in the terminal device  100  as described above, the contents providing unit  250  recognizes the reproducing time information of the specific reproducing period (for example, the reproducing period  2 ) selected to be reproduced and, when the corresponding content (for example, the video content  1 ) exists in the contents storage unit  230 , provides the corresponding content (for example, the video content  1 ) stored in the contents storage unit  230  to the terminal device  100  in synchronization with the recognized reproducing time information. 
     That is, when the specific reproducing period (for example, the reproducing period  2 ) is selected to be reproduced from the popularity indication bar with respect to the content (for example, the video content  1 ) published in a predetermined contents providing server (for example, the contents providing server A  300 A) based on the search result displayed on the terminal device  100  as described above or when the information on the content (for example, the video content  1 ) in the specific reproducing period (for example, the reproducing period  2 ) is selected to be reproduced from the displayed information on the content (for example, the video content  1 ) in each of the reproducing periods, the contents providing unit  250  recognizes the reproducing time information (for example, reproducing starts at 10 minutes and ends at 20 minutes in the reproducing period  2 ) in accordance with the selection performed by the terminal device  100  to be reproduced and determines whether the corresponding content (for example, the video content  1 ) exists in the contents storage unit  230 . 
     When the corresponding content (for example, the video content  1 ) exists in the contents storage unit  230 , the contents providing unit  250  may provide the corresponding content (for example, the video content  1 ) stored in the contents storage unit  230  to the terminal device  100  in synchronization with the recognized reproducing time information (for example, reproducing starts at 10 minutes and 00 seconds and ends at 20 minutes and 00 seconds). 
     On the other hand, when the corresponding content (for example, the video content  1 ) does not exist in the contents storage unit  230 , the contents providing unit  250  provides the contents providing server related information and the contents related information that are included in the search result (the result currently displayed on the terminal device  100 ) provided by the search result providing unit  240  to the terminal device  100  so that the terminal device  100  may receive the content (for example, the video content  1 ) of the specific reproducing period (for example, the reproducing period  2 ) selected to be reproduced from the corresponding contents providing server (for example, the contents providing server A  300 A). 
     When the specific reproducing period (for example, the reproducing period  2 ) is selected by the terminal device  100  to be reproduced with respect to the content (for example, the video content  1 ) published in the specific contents providing server (for example, the contents providing server A  300 A) based on the search result, the contents providing unit  250  does not immediately have the terminal device  100  connected to the corresponding contents providing server A  300 A but, when the same content (for example, the video content  1 ) possessed by the contents search service providing server  200  exists, has the specific reproducing period (for example, the reproducing period  2 ) reproduced by the terminal device  100  with respect to the possessed content (for example, the video content  1 ). 
     In a state where the terminal device  100  displays the contents providing server which provides/possesses the corresponding content (for example, the XX drama episode 3—the video content  1 ) in accordance with the search result, and displays the popularity indication bar by which it is possible to identify the total number of hits of the corresponding content (for example, the XX drama episode 3—the video content  1 ) with respect to each of the reproducing periods, that is, the popularity of the corresponding content (for example, the XX drama episode 3—the video content  1 ) with respect to each of the reproducing periods in accordance with the total hits information with respect to each of reproducing periods for the corresponding content (for example, the XX drama episode 3—the video content  1 ), when a user selects a specific reproducing period (for example, reproducing period  2 ) of a content (for example, the video content  1 ) provided by the specific contents providing server to be reproduced, the user may easily reproduce/view the reproducing period  2  of the video content  1  selected to be reproduced. 
     As described above, the contents search service system according to the present invention manages total hits information with respect to each of reproducing periods for each of the contents through inter-working with all the contents providing servers  300 A to  300 N on the Web. Further, when it is requested by the terminal device  100  to search for certain content, the contents search service system according to the present invention provides hits information with respect to each of reproducing periods for the corresponding content to the terminal device  100  together with the search result of the corresponding content. As a result, the contents search service system can provide total hits information with respect to each of reproducing periods, that is, the popularity of each of the contents with respect to each of reproducing periods not in a limited range of a specific portal service but in the entire Web environment to the user of the terminal device  100 . 
     That is, the contents search service system according to the present invention provides the popularity of each of the contents with respect to each of reproducing periods not in the limited range of the specific portal service but in the entire Web environment to the user of the contents search service and further provides detailed information such as the title of a corresponding reproducing period, the additional comments in the corresponding reproducing period, and the story of the corresponding reproducing period with respect to each of the reproducing periods to the user so that the contents search service system may provide a reliable, detailed, and effective contents search service to the user. 
     Hereinafter, a contents search service method according to the present invention will be described with reference to  FIGS. 3 and 4 . For convenience sake, description will be made by mentioning the reference numerals of  FIGS. 1 and 2 . 
     First, when the contents search service method according to the present invention is described with reference to  FIG. 3 , in the contents search service method according to the present invention, each of the contents providing servers  300 A to  300 N for managing hits information with respect to each of reproducing periods for each of the contents possessed by each of the contents providing servers  300 A to  300 N is inter-working with the contents search service providing server  200  (S 10 ). 
     The contents search service providing server  200  generates and manages total hits information with respect to each of reproducing periods for each of the contents based on the at least one hits information with respect to each of reproducing periods that is collected from each of the contents providing servers  300 A to  300 N in S 10  (S 20 ). 
     The terminal device  100  provides the search word (for example, the XX drama episode 3) input by the user to the contents search service providing server  200  to request the contents search service providing server  200  to search the content corresponding to the search word (for example, the XX drama episode 3) (S 30 ). 
     When it is requested by the terminal device  100  to search the content, the contents search service providing server  200  searches for the content (for example, the XX drama episode 3—the video content  1 ) requested by the terminal device  100  to be searched for through clustering in accordance with the contents search service providing server  200  inter-working with each of the contents providing servers  300 A to  300 N (S 40 ). 
     The contents search service providing server  200  provides the search result of the search performed in S 40  and the total hits information with respect to each of reproducing periods for the corresponding content to the terminal device  100  (S 50 ). 
     The terminal device  100  displays the contents providing server which provides/possesses the corresponding content (for example, the XX drama episode 3—the video content  1 ) in accordance with the provided search result and displays (for example, in the form of the popularity indication bar) the total number of hits that the corresponding content (for example, the XX drama episode 3—the video content  1 ) to be identified in accordance with the total hits information with respect to each of reproducing periods for the corresponding content (for example, the XX drama episode 3—the video content  1 ). The user of the terminal device  100  recognizes the contents providing servers that provide/possess the content (for example, the XX drama episode 3—the video content  1 ) requested to be searched for and, in particular, may check the popularity of the corresponding content (for example, the XX drama episode 3—the video content  1 ) in reproducing period basis at a look. 
     Hereinafter, the service providing method of the contents search service providing server  200  according to the present invention will be described in detail with reference to  FIG. 4 . 
     In the service providing method of the contents search service providing server  200  according to the present invention, in accordance with the generation of a periodic or predetermined event (for example, the request performed by the terminal device  100  to search for the content), the at least one hits information with respect to each of reproducing periods for each of the contents providing servers  300 A to  300 N is collected by the contents search service providing server  200  inter-working with each of the contents providing servers  300 A to  300 N and the total hits information with respect to each of reproducing periods for each of the contents is generated and managed based on the at least one hits information with respect to each of reproducing periods (S 110 ). 
     That is, in the service providing method of the contents search service providing server  200  according to the present invention, the contents search service providing server  200  collects the hits information with respect to each of reproducing periods for each of the contents possessed by each of the contents providing servers  300 A to  300 N. 
     At this time, when the contents providing server A  300 A and the contents providing server N  300 N possess the same content (for example, the video content  1 ), in the service providing method of the contents search service providing server  200  according to the present invention, the hits information A with respect to each of reproducing periods for the corresponding content (for example, the video content  1 ) is collected from the contents providing server A  300 A and the hits information N with respect to each of reproducing periods for the corresponding content (for example, the video content  1 ) is collected from the contents providing server N  300 N. 
     In the service providing method of the contents search service providing server  200  according to the present invention, with respect to each of the various contents possessed by each of the contents providing servers  300 A to  300 N, only one hits information with respect to each of reproducing periods for a certain content (for example, the video content  3 ) may be collected and various hits information with respect to each of reproducing periods (for example, hits information with respect to each of reproducing periods A, B, and N) for a certain content (for example, the video content  1 ) may be collected. 
     In the service providing method of the contents search service providing server  200  according to the present invention, as described above, the total hits information with respect to each of reproducing periods for each of the contents possessed by each of the contents providing servers  300 A to  300 N is generated and managed based on the at least one hits information with respect to each of reproducing periods for each of the contents possessed by each of the contents providing servers  300 A to  300 N. 
     For example, in the service providing method of the contents search service providing server  200  according to the present invention, when the only one hits information with respect to each of reproducing periods for a predetermined content (for example, the video content  3 ) is collected, the total hits information with respect to each of reproducing periods for the corresponding content (for example, the video content  3 ) may be generated by applying the only one hits information with respect to each of reproducing periods for the corresponding content (for example, the video content  3 ) as the total hits information with respect to each of reproducing periods for the corresponding content (for example, the video content  3 ). In addition, in the service providing method of the contents search service providing server  200  according to the present invention, when the various hits information with respect to each of reproducing periods (for example, the hits information with respect to each of reproducing periods A, B, and N) for predetermined content (for example, the video content  1 ) are collected, hits information with respect to reproducing period for the content (for example, the video content  1 ) are summed up based on the various hits information with respect to each of reproducing periods (for example, hits information with respect to each of reproducing periods A, B, and N) for the content (for example, the video content  1 ) to generate the total hits information with respect to each of reproducing periods for the content (for example, the video content  1 ). 
     At this time, when the number of users of a specific contents providing server (for example, the contents providing server A  300 A) is remarkably larger than the number of users of the other servers so that the number of hits that the content has in the contents providing server A  300 A is particularly high, it may be necessary to perform normalization in generating the total hits information with respect to each of reproducing periods for each of the contents based on the at least one hits information with respect to each of reproducing periods that is collected from each of the contents providing servers  300 A to  300 N. 
     In the service providing method of the contents search service providing server  200  according to the present invention, in performing  5110  of generating total hits information with respect to each of reproducing periods for each of the contents based on the at least one hits information with respect to each of reproducing periods that is collected through inter-working with each of the contents providing servers  300 A to  300 N as described above, the hit number information managing unit  210  normalizes the at least one hits information with respect to each of reproducing periods and generates total hits information with respect to each of reproducing periods for a corresponding content by summing up the number of hits based on the normalized at least one hits information with respect to each of reproducing periods. 
     For example, in the service providing method of the contents search service providing server  200  according to the present invention, with respect to the at least one hits information with respect to each of reproducing periods (for example, hits information with respect to each of reproducing periods A, B, and N) for a predetermined content (for example, the video content  1 ), the hit number information managing unit  210  recognizes the entire hits, the number of reproducing periods, and the average number of hits from corresponding hits information with respect to each of reproducing periods for the content (for example, the video content  1 ) and normalizes the corresponding hits information with respect to each of reproducing periods based on the recognized average number of hits. 
     That is, when it is assumed that the hits information A for the content (for example, the video content  1 ) indicates that the number of hits is 4,000 in reproducing period  1 , that the number of hits is 2,000 in reproducing period  2 , that the number of hits is 1,000 in reproducing period  3 , that the number of hits is 5,000 in reproducing period  4 , and that the number of hits is 5,000 in reproducing period  5 , in the service providing method of the contents search service providing server  200  according to the present invention, the hit number information managing unit  210  may recognize that the entire hits are 17,000 (4,000+2,000+1,000+5,000+5,000), that the number of reproducing periods is 5, and that the average number of hits is 3,400 (17,000/5) from the hits information A for the content (for example, the video content  1 ) and may draw hits information A (indicating that the number of hits is 1.2 in the reproducing period  1 , that the number of hits is 0.6 in the reproducing period  2 , that the number of hits is 0.3 in the reproducing period  3 , that the number of hits is 1.5 in the reproducing period  4 , and that the number of hits is 1.5 in the reproducing period  5 ) (for example, rounding off the numbers to two decimal places) for the content (for example, the video content  1 ) normalized by dividing the corresponding hits information A by the recognized average number of hits (3,400). In such a method, hits information with respect to each of reproducing periods B and N may be normalized. 
     In the service providing method of the contents search service providing server  200  according to the present invention, with respect to the normalized information (for example, the hits information with respect to each of reproducing periods A, B, and N) for the corresponding content (for example, the video content  1 ), the hit number information managing unit  210  may generate total hits information with respect to each of reproducing periods (indicating that the number of hits is X 1  in the reproducing period  1 , that the number of hits is X 2  in the reproducing period  2 , that the number of hits is X 3  in the reproducing period  3 , that the number of hits is X 4  in the reproducing period  4 , and that the number of hits is X 5  in the reproducing period  5 ) for the corresponding content (for example, the video content  1 ) by summing up hits information with respect to each of reproducing periods. 
     In the service providing method of the contents search service providing server  200  according to the present invention, in accordance with the generation of a periodic or predetermined event (for example, the request performed by the terminal device  100  to search for the content), the at least one information item on each of the contents possessed by each of the contents providing servers  300 A to  300 N is collected by the contents search service providing server  200  inter-working with each of the contents providing servers  300 A to  300 N and hits information with respect to each of reproducing periods for the contents possessed by each of the contents providing servers  300 A to  300 N is generated and managed based on the at least one information item on each of the contents (S 120 ). 
     For example, in the service providing method of the contents search service providing server  200  according to the present invention, information on each of the contents possessed by each of the contents providing servers  300 A to  300 N is collected from each of the contents providing servers  300 A to  300 N. Here, the content information includes the meta information (for example, the content identification information, the content title information, the total reproducing time information, the information on reproducing time with respect to reproducing periods that represents the start of reproducing and the end of reproducing, the genre information, the theme information, the character information, and the story information) of the corresponding content (for example, the video content  1 ) and the additional comment information (for example, the comments, the reviews, and the questions) in each of the reproducing periods of the corresponding content (for example, the video content  1 ), and the information on the title of each of the reproducing periods (for example, the title of a reproducing period and the story of a reproducing period) as described above when the contents providing servers  300 A to  300 N are described. 
     At this time, when the contents providing server A  300 A and the contents providing server N  300 N possess the same content (for example, the video content  1 ), in the service providing method of the contents search service providing server  200  according to the present invention, information A on the corresponding content (for example, the video content  1 ) is collected from the contents providing server A  300 A and information N on the corresponding content (for example, the video content  1 ) is collected from the contents providing server N  300 N. 
     In the service providing method of the contents search service providing server  200  according to the present invention, with respect to each of the various contents possessed by each of the contents providing servers  300 A to  300 N, the only one information item on a certain content (for the video content  3 ) and various information items (for example, the content information items A, B, and N) on a certain content (for example, the video content  1 ) may be collected. 
     The information on each of the contents in each of the reproducing periods is generated and managed based on the information on each of the contents that is collected by the contents search service providing server  200  inter-working with each of the contents providing servers  300 A to  300 N. 
     For example, in the service providing method of the contents search service providing server  200  according to the present invention, when the only one content information item on a predetermined content (for example, the video content  3 ) is collected, the information on each of the contents in each of the reproducing periods including at least one of the title, the additional comments (for example, the comments, the reviews, and the questions), and the story of a corresponding reproducing period (for example, the reproducing period  1 ) with respect to the reproducing periods (for example, the reproducing periods  1 ,  2 ,  3 ,  4 , and  5 ) may be generated based on the information (for example, the meta information, the additional comment information in each of the reproducing periods, and the information on the title of each of the reproducing periods) on the corresponding content (for example, the video content  3 ). In addition, in the service providing method of the contents search service providing server  200  according to the present invention, when the various information items (for example, the content information items A, B, and N) on a predetermined content (for example, the video content  1 ) are collected, the information on each of the contents in each of the reproducing periods including at least one of the title, the additional comments (for example, the comments, the reviews, and the questions), and the story of a corresponding reproducing period (for example, the reproducing period  1 ) with respect to the reproducing periods (for example, the reproducing periods  1 ,  2 ,  3 ,  4 , and  5 ) may be generated based on the various content information items (for example, the content information items A, B, and N). 
     On the other hand, in the service providing method of the contents search service providing server  200  according to the present invention, when it is requested by the terminal device  100  to search for the content corresponding to the predetermined search word (for example, the XX drama episode 3) (S 130 ), the content (for example, the XX drama episode 3—the video content  1 ) requested to be searched for is searched for through clustering in accordance with the contents search service providing server  200  inter-working with each of the contents providing servers  300 A to  300 N (S 140 ). Here, since a conventional clustering method may be adopted as a method of searching for content on the Web through clustering, a detailed description thereof will be omitted. 
     In the service providing method of the contents search service providing server  200  according to the present invention, the search result of the search performed in S 140  and total hits information with respect to each of reproducing periods for the corresponding content (for example, the XX drama episode 3—the video content  1 ) are provided to the terminal device  100  (S 150 ). 
     That is, in the service providing method of the contents search service providing server  200  according to the present invention, the search result including at least one of information on a corresponding contents providing server that provides/possesses the content (for example, the XX drama episode 3—the video content  1 ) searched for in accordance with the search request of the terminal device  100  and information on corresponding contents published in a corresponding contents providing server, and the total hit number information on the number of hits of the corresponding content (for example, the XX drama episode 3—the video content  1 ) with respect to each of the reproducing periods, which is managed in step S 110 , are provided to the terminal device  100 , so that the terminal device  100  displays the search result and displays a popularity indication bar by which it is possible to identify the total number of hits for the corresponding content (for example, the XX drama episode 3—the video content  1 ) in reproducing period basis. 
     When the contents providing server A  300 A and the contents providing server N  300 N provide/possess the searched content (for example, the XX drama episode 3—the video content  1 ), the contents providing server related information may include the service name information, the access address information, and the image information representing a corresponding server of the contents providing server A  300 A and the contents providing server N  300 N. 
     The contents related information may include the storage position information, the content identification information, the content title information, and the thumbnail information of the corresponding content (for example, the XX drama episode 3—the video content  1 ) in a corresponding contents providing server (for example, the contents providing servers  300 A and  300 N). 
     When the search result and total hits information with respect to each of reproducing periods are provided from the contents search service providing server  200  in accordance with the search request, the terminal device  100  displays the contents providing server which provides/possesses the corresponding content (for example, the XX drama episode 3—the video content  1 ) in accordance with the search result, and displays the popularity indication bar, by which it is possible to identify the total number of hits for the corresponding content (for example, the XX drama episode 3—the video content  1 ) in reproducing period basis, in accordance with total hits information with respect to each of reproducing periods for the corresponding content (for example, the XX drama episode 3—the video content  1 ). At this time, in the popularity indication bar, different display colors may be preferably assigned in accordance with the range of the previously set total number of hits so that each of the reproducing periods has a display color in accordance with the range to which the corresponding total number of hits belongs. Here, the display color assigned in accordance with the range of the total number of hits is preferably darker as the total number of hits is larger, that is, the popularity is higher and is preferably lighter as the total number of hits is smaller, that is, the popularity is lower. 
     Therefore, the user of the terminal device  100  recognizes the contents providing servers that provide/possess the content (for example, the XX drama episode 3—the video content  1 ) requested to be searched for and, in particular, may check the popularity of the corresponding content (for example, the XX drama episode 3—the video content  1 ) in reproducing period basis at a look. 
     On the other hand, in the service providing method of the contents search service providing server  200  according to the present invention, when the search result in accordance with the request performed by the terminal device  100  to search for the content (for example, the XX drama episode 3—the video content  1 ) and the total hits information with respect to each of reproducing periods for the corresponding content (for example, the video content  1 ) are provided to the terminal device  100  in step S 150 , the contents search service providing server  200  may further provide period contents information on the corresponding content (for example, video content  1 ) with respect to each of the reproducing periods to the terminal device  100 , so as to further display the period contents information on the content (for example, the video content  1 ) with respect to each of the reproducing periods in the terminal device  100  when the search result and the popularity indication bar, by which it is possible to identify the total number of hits that the content (for example, the video content  1 ) with respect to each of the reproducing periods, are displayed in the terminal device  100 . 
     That is, in the service providing method of the contents search service providing server  200  according to the present invention, in providing the search result and the total hits information with respect to each of reproducing periods for the corresponding content (for example, the video content  1 ) are provided to the terminal device  100  as described above in accordance with the request performed by the terminal device  100  to search for the content (for example, the XX drama episode 3—the video content  1 ), the information on the corresponding content (for example, the video content  1 ) with respect to each of the reproducing periods that is managed in S 120  may be further provided to the terminal device  100 . 
     When the search result, the total hits information with respect to each of reproducing periods for the content (for example, the video content  1 ), and the information on the content (for example, the video content  1 ) with respect to each of the reproducing periods have been provided from the contents search service providing server  200  in accordance with the search request, the terminal device  100  displays the contents providing server which provides/possesses the corresponding content (for example, the XX drama episode 3—the video content  1 ) in accordance with the search result, and displays the popularity indication bar, by which it is possible to identify the total number of hits for the corresponding content (for example, the XX drama episode 3—the video content  1 ) with respect to each of the reproducing periods, in accordance with total hits information with respect to each of reproducing periods for the corresponding content (for example, the XX drama episode 3—the video content  1 ). Further, the terminal device  100  may display the information on the corresponding content (for example, the XX drama episode 3—the video content  1 ) with respect to each of the reproducing periods, which includes at least one of period title, additional comments, and the story of each of the reproducing periods, in accordance with the information on the corresponding content (for example, the XX drama episode 3—the video content  1 ) with respect to each of the reproducing periods. 
     Therefore, the user of the terminal device  100  recognizes the contents providing servers that provide/possess the content (for example, the XX drama episode 3—the video content  1 ) requested to be searched for and, in particular, may conveniently check the popularity of the corresponding content (for example, the XX drama episode 3—the video content  1 ) with respect to each of the reproducing periods, the title of each of the reproducing periods, the brief story of each of the reproducing periods, and the additional comments of the other users in the corresponding reproducing period at a look. 
     On the other hand, as described above, a specific reproducing period (for example, the reproducing period  2 ) on the popularity indication bar may be indicated by the terminal device  100  which displays the search result and the popularity indication bar, by which it is possible to identify the total number of hits for the content (for example, the XX drama episode 3—the video content  1 ) with respect to each of the reproducing periods, based on the search result and the total hits information with respect to each of reproducing periods for the content (for example, the XX drama episode 3—the video content  1 ), which have been provided in accordance with the request to search for the content (for example, the XX drama episode 3—the video content  1 ). 
     Therefore, in the service providing method of the contents search service providing server  200  according to the present invention, the contents search service providing server  200  determines whether the specific reproducing period (for example, the reproducing period  2 ) on the popularity indication bar is indicated by the terminal device  100  (S 160 ). Then, when the specific reproducing period (for example, the reproducing period  2 ) is indicated, the contents search service providing server  200  provides period contents information, which corresponds to an indicated specific reproducing period (for example, reproducing period  2 ) among the period contents information of each reproducing period managed in step S 120  in accordance with the corresponding content (for example, the video content  1 ), to the terminal device  100  (S 170 ), so as to display the period contents information, which includes at least one of the period title, additional comuents, and the story of the reproducing period (for example, the reproducing period  2 ). 
     Therefore, in the state where the terminal device  100  displays the contents providing server which provides/possesses the corresponding content (for example, the XX drama episode 3—the video content  1 ) in accordance with the search result, and displays the popularity indication bar, by which it is possible to identify the total number of hits for the corresponding content (for example, the XX drama episode 3—the video content  1 ) with respect to each of the reproducing periods, that is, the popularity of the content (for example, the XX drama episode 3—the video content  1 ) with respect to each of the reproducing periods, in accordance with the total hits information with respect to each of reproducing periods for the content (for example, the XX drama episode 3—the video content  1 ), the user may indicate a specific reproducing period to conveniently identify the title of the specific reproducing period, the brief story of the specific reproducing period, and additional comments of the other users in the specific reproducing period. 
     In the service providing method of the contents search service providing server  200  according to the present invention, when a specific reproducing period (for example, the reproducing period  2 ) is selected to be reproduced with respect to the content (for example, the video content  1 ) published in a predetermined contents providing server (for example, the contents providing server A  300 A based on the search result displayed on the terminal device  100  as described above, the reproducing time information of the specific reproducing period (for example, the reproducing period  2 ) selected to be reproduced is recognized and, when the corresponding content (for example, the video content  1 ) stored in and possessed by the contents search service providing server  200  exists, the corresponding content (for example, the video content  1 ) stored in the contents search service providing server  200  is provided to the terminal device  100  in synchronization with the recognized reproducing time information. 
     That is, in the service providing method of the contents search service providing server  200  according to the present invention, based on the search result displayed in the terminal device  100  as described above, with respect to the content (for example, the video content  1 ) published in a predetermined contents providing server (for example, the contents providing server A  300 A), it is determined whether the specific reproducing period (for example, the reproducing period  2 ) is selected to be reproduced from the popularity indication bar or whether the information on the content (for example, the video content  1 ) in the specific reproducing period (for example, the reproducing period  2 ) is selected to be reproduced from the displayed information on the content (for example, the reproducing period  2 ), so as to determine whether the specific reproducing period (for example, the reproducing period  2 ) is selected to be reproduced (S 180 ). 
     When the specific reproducing period (for example, the reproducing period  2 ) is selected by the terminal device  100  to be reproduced, in the service providing method of the contents search service providing server  200  according to the present invention, the reproducing time information (for example, reproducing starts at 10 minutes and ends at 20 minutes in the reproducing period  2 ) in accordance with the selection performed by the terminal device  100  to be reproduced is recognized and it is determined whether the corresponding content (for example, the video content  1 ) stored in and possessed by the contents search service providing server  200  exists (S 190 ).

     On the other hand, when the corresponding content (for example, the video content  1 ) stored in the contents search service providing server  200  does not exist, in the service providing method of the contents search service providing server  200  according to the present invention, the contents providing server related information and the contents related information that are included in the search result (the result currently displayed in the terminal device  100 ) provided to the terminal device  100  in  5150  are provided to the terminal device  100  so that the terminal device  100  may receive the content (for example, the video content  1 ) of the specific reproducing period (for example, the reproducing period  2 ) selected to be reproduced from the corresponding contents providing server (for example, the contents providing server A  300 A) (S 210 ). 
     In the service providing method of the contents search service providing server  200  according to the present invention, when the specific reproducing period (for example, the reproducing period  2 ) is selected by the terminal device  100  to be reproduced with respect to the content (for example, the video content  1 ) published in the specific contents providing server (for example, the contents providing server A  300 A) based on the search result, the contents providing unit  250  does not immediately have the terminal device  100  connected to the corresponding contents providing server A  300 A but, when the same content (for example, the video content  1 ) possessed by the contents search service providing server  200  exists, has the specific reproducing period (for example, the reproducing period  2 ) reproduced by the terminal device  100  with respect to the possessed content (for example, the video content  1 ). 
     In the state where the terminal device  100  displays the contents providing server which provides/possesses the corresponding content (for example, the XX drama episode 3—the video content  1 ) in accordance with the search result and displays the popularity indication bar, by which it is possible to identify the total number of hits of the corresponding content (for example, the XX drama episode 3—the video content  1 ) in each of the reproducing periods, that is, the popularity of the corresponding content (for example, the XX drama episode 3—the video content  1 ) in each of the reproducing periods, in accordance with total hits information with respect to each of reproducing periods for the corresponding content (for example, the XX drama episode 3—the video content  1 ), when the user selects the specific reproducing period (for example, the reproducing period  2 ) of the content (for example, the video content  1 ) provided by the specific contents providing server to be reproduced, the user may easily reproduce and view the reproducing period  2  of the video content  1  selected to be reproduced. 
     As described above, the contents search service method according to the present invention manages total hits information with respect to each of reproducing periods for each of the contents through inter-working with all the contents providing servers  300 A to  300 N on the Web. Further, when it is requested by the terminal device  100  to search for certain content, the contents search service method according to the present invention provides hits information with respect to each of reproducing periods for the corresponding content to the terminal device  100  together with the search result of the corresponding content.
