The present invention relates to a method for generating an index of multimedia content, and more particularly, in an apparatus for providing P2P-based multimedia content streaming, an index generator is executed while being connected to an intermediate server to generate an index file for multimedia content. Rather, it forms a hierarchical structure for geographic information and selects geographic information for each layer to input all the geographic information for all hierarchies. The present invention relates to an index generation method of multimedia content.

In recent years, due to the expansion of computer capacity, activation of Internet usage, and the spread of high-speed communication networks, the distinction between the roles of clients and servers becomes ambiguous so that clients who have only received services from servers can act as servers. Peer to Peer (based on Peer to Peer) is becoming more common, and interest in multimedia content including video, voice, etc., which are large in size, provides services among individuals.

As the P2P foundation is generalized, P2P sharing programs such as eDonkey, Pruna, Guru Guru, and Media Vamp are increasing, and multimedia contents are mutually provided through these sharing programs.

However, the method of providing multimedia contents using this method is to send from the beginning to the end of each file unit. If the other party wants only a specific part, the original multimedia content is edited and encoded to form a new file. If you provide the original multimedia content file to the other party, you can save it on your computer, edit and encode it directly, or simply run the player and move the search bar to the part that you think it is. There is no problem.

Accordingly, the present applicant has registered a patent No. 10-0407033 (Nov. 13, 2003) "a method of constructing a database by an information modeling method and searching for information using the constructed database" and a registered patent No. 10-0518724 (2005). 10. 04) "Multimedia information database construction and retrieval service providing method and system" and Korean Patent Publication No. 2004-0052057 (2004. 06. 19) "Sales system of video content and its operation method" and Korean Patent Publication No. 2004-0073654 (2004. 08. 21) Through the "Section Extraction System of Video Contents", a database is built by forming an index for a specific section in terms of time, objects, spaces, and objects for multimedia contents, and a specific section is desired among all multimedia contents. Search and extract only those parts to serve over the wired / wireless internet and add search terms to the index when extracting those parts. Presenting a system and method to enable the search and retrieval of prizes, and to activate the transaction and service of video contents online by extracting only a part of the file at a low price rather than the entire video file so that it can be serviced through wired and wireless Internet. I've done it.

However, the above method is about a method that is performed between a server that provides multimedia content and a client of an individual, and many people search for and share each other's multimedia contents owned by individuals on a P2P basis. There is a problem with how to do this.

Therefore, it is possible to analyze specific sections in terms of time, objects, spaces, and objects for multimedia contents owned by individuals, extract keywords, create index files that record start and end times of sections, and search and share index files among individuals. P2P-based multimedia content streaming apparatus that enables the peer to perform streaming on a specific section from P2P-based to the requesting partner when requesting a specific section of multimedia content by executing it on a peer-to-peer basis. And for the method, the applicant has filed on September 30, 2005, patent application 10-2005-0091767 and patent application 10-2005-0091768.

1 is a block diagram schematically illustrating a P2P based multimedia content streaming apparatus according to the prior art.

As shown here, the apparatus for providing multimedia content streaming is installed in each of the computer 10 and the counterpart computer 20, and receives the IP address of the computer 10 connected through the intermediary server 70 and directly receives the IP address. When the user accesses the user's computer 10 to search the index file and executes the searched index file, the user's computer 10 operates as a server to provide multimedia content streaming on a P2P basis. When the multimedia content streaming request is requested, the multimedia content streaming is operated as a client to receive and play the multimedia content streaming on a P2P basis.

The configuration includes an index generator 40 for generating a hierarchical video index information, an index file including client IP, multimedia content information, and broadcasting information for multimedia content stored in a computer, and the index generator 40. The streaming provider 30 is shared so that the searched index file can be searched, and provides a specific section requested according to the index by streaming on a P2P basis, and a plurality of own computers 10 or counterpart computers connected through a network ( 20) an IP address server for storing and managing IP addresses, and providing an IP address when a search request is made, and an index for searching an index file stored in the IP address by receiving an IP address connected from the IP server 70 The search unit 60 and the streaming provider 30 of the selected IP address as the index file searched by the index search unit 60 is executed. P2P server-based index composed of players (50) for playing a streaming provided.

The index file and the multimedia content file thus formed are located in the streaming provider 30 so that the counterpart computer 20 can search for the index file and provide it when a streaming request is made.

Therefore, when the computer 10 and the counterpart computer 20 are connected to the intermediary server 70 online (①), the counterpart computer 20 operates as a client that searches and plays the multimedia content to receive the multimedia content. When the computer 10 shares and searches the index file and operates as a server that provides multimedia content streaming, the streaming provider generates the index file (②) generated by the index generator 40 of the own computer 10. (30) share the location, and when the counterpart computer 20 requests the index file search from the counterpart server 70 (③), the IP addresses stored in the intermediary server 70 are provided to the counterpart computer 20 (④). When the other computer 20 accesses the provided IP address (⑤), searches the index file shared by the own computer 10 (⑥), and executes the index file listed (⑦). The user of the computer according to the P2P-based access from the index player 50 of the 20 to the user's computer 10 to the streaming provider 30 to provide the multimedia content streaming of the specific section by the index file (⑧). It is possible to play (⑨) the multimedia content streaming provided by (10) in the counterpart computer (20).

In this case, when there are a plurality of own computers 10 connected to the intermediate server 70, the index search unit of the counterpart computer 20 receives IP addresses of the plurality of own computers 10 from the intermediate server 70 and accesses each of them. It will search the index file and list the search results.

In order to search for multimedia content through the multimedia content streaming providing device provided as described above, the index file generated by the index generator 40 is searched. Also, if the same keyword is not inputted by inputting each keyword through a different keyword, there is a problem in that similar contents are not searched.

In addition, in the case of geographic information, a plurality of hierarchical structures are formed. However, when only a lower layer is input when extracting and inputting a keyword, there is a problem that a search is not performed even though a lower layer is included when searching by an upper layer.

In other words, when registering the multimedia contents of case A occurred in "Gangnam-gu Yeoksam-dong" and the contents of multimedia content of case B occurred in "Daechi-dong, Gangnam-gu," when entering a keyword, the case A entered "Yeoksam-dong", and the case B of "Gangnam-gu." If you enter "and" Daechi-dong "when the user enters" Gangnam-gu "to search only B events will be searched.

Since this search is based on the keywords entered while creating the index file, case A without entering "Gangnam-gu" will not be searched. By the way, "Yeoksam-dong" should be searched when searching for "Gangnam-gu" as the lower-level geographic information of "Gangnam-gu", but not searched. Also, if you search for "Seoul", both A and B events will not be searched. There is this.

The present invention was created to solve the above problems, and an object of the present invention is to create an index file for multimedia content by executing an index generator in a state of being connected to an intermediate server in a P2P-based multimedia content streaming apparatus. In addition to forming a hierarchical structure for geographic information and selecting geographic information for each layer to input all geographic information for all hierarchies, sublayers are searched for multimedia content based on geographic information. An object of the present invention is to provide an index generation method for multimedia content.

The present invention for achieving the above object is to create an index file for a specific section of the multimedia content streaming through the index generator to search each other on a P2P basis through the intermediary server to provide multimedia content streaming in a specific section unit In the apparatus for providing multimedia content streaming, a first step of accessing an intermediary server to execute an index generator, and a second step of determining whether to input geographic information for generating an index file when the index generator is executed, and inputting geographic information. Is selected, a third step of displaying a hierarchical structure defined for inputting geographic information; and a fourth step of selecting any one of predetermined geographic information according to each layer from the highest layer to the lowest layer sequentially in the displayed hierarchy. And the lowest in the fourth stage A fifth step of generating an index file by inputting all the information about preset geographic information according to the selected layer and the lower layers of the selected layer when the selection of the geographic information for the above layer is completed or the selection of the geographic information is completed. Characterized in that it comprises a step.

In the present invention, the hierarchical structure of geographic information is defined as five layers including a country.

Geographic information in the present invention is characterized in that the name of the administrative unit.

In the present invention, if there is no desired geographic information among the geographic information preset in the fourth step, the method further comprises a step of setting the geographic information hierarchically.

At this time, when setting the geographic information is characterized in that the setting is determined by determining similarity and identity with the predetermined geographic information.

In the fifth step of the present invention, after the input of the geographic information, a general keyword input may be added.

In the present invention, the index file is generated by the index generator and then stored in an intermediary server.

According to the present invention, the index generator is executed when accessing an intermediary server, and when the index file for multimedia content is generated, the geographic information preset for all layers from the highest layer to the lowest layer according to the hierarchical structure is used. By selecting and inputting the same, the geographic information of the lower layer may be searched when the multimedia content is searched by the geographic information.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings, and the same parts as in the prior art use the same reference numerals and names. In addition, the present embodiment is not intended to limit the scope of the present invention, but is presented by way of example only and those skilled in the art will be capable of many modifications within the technical spirit of the present invention.

2 is a flowchart illustrating a method of generating an index of multimedia content according to the present invention.

First, when accessing and logging in to the intermediary server 70 through the own computer 10, the index generator 40 is automatically installed and executed on the web (S10) (S20).

When the index generator 40 is executed as described above, an index file is generated to be shared and searched for the multimedia contents stored in the personal computer 10.

When generating an index file, if the user wants to input an index word inputted through geographic information to search a keyword for multimedia content (S14).

In this case, if the geographic information input is not selected, an index file is generated by receiving a keyword according to a keyword input method according to a general method (S36).

However, when selecting the geographic information input from above, the hierarchical structure according to the administrative unit is defined in advance so that the geographic information by the administrative unit can be hierarchically selected and the defined hierarchical structure is displayed (S16).

For example, in the case of Korea, it is defined as 5 tiers as a country, city, city, county, mundong, zip code, etc., and in the United States, it is defined as 5 tiers such as COUNTRY, STATE, CITY, STREET, and NUMBER. As defined, it is defined by classifying according to each administrative unit.

When each layer is sequentially selected from the highest layer to the lowest layer according to the displayed hierarchical structure, geographic information preset in the selected layer is displayed (S18) (S20). At this time, the selected geographic information among the displayed geographic information is selected (S22).

Then, the predetermined geographic information is displayed as a lower layer according to the selected geographic information so that the predetermined geographic information can be selected and input sequentially up to the lowest layer (S26).

By selecting among the geographic information defined as described above, all people can use the same geographic information so that they can be set differently according to the individual or enter a different name to solve the problem of not being searched.

However, when there is geographic information that is not set among geographic information displayed in the selected layer, it is possible to additionally set the geographic information of the corresponding layer to form a new layer (S28) (S30). However, in the case of additionally setting in this way, the unity can be increased by determining the similarity and the sameness to the preset geographic information to allow or reserve the setting.

In this way, the user selects all the geographic information for the lowest layer to complete the input (S24) or completes the input without entering the geographic information for the lower layer (S32). An index file is generated (S38).

On the other hand, even after selecting and inputting the geographic information as described above, it is also possible to add a general keyword input to perform a search by various conditions (S34) (S36).

The index file generated as described above may be stored in the mediation server 70.

When the index file is created by the above method, the geographic information in the index file is input from the highest level to the lowest level to the lower layer of the geographic information input for future search by inputting unified geographic information according to administrative units. You can get the result of the search.

That is, as mentioned in the conventional problem, when entering through the geographic information on the case A, as a keyword, all geographic information of the administrative units of "Korea", "Seoul-si", "Gangnam-gu", "Yeoksam-dong", and "828" If the case B is entered through geographic information, all geographic information of the administrative units of "Korea", "Seoul City", "Gangnam-gu", "Daechi-dong", and "100" will be entered as keywords.

Thus, even if only "Gangnam-gu" is entered in the search, the search is made in both A and B events.

As described above, the present invention provides an apparatus for providing P2P-based multimedia content streaming to generate an index file for multimedia content by executing an index generator while connected to an intermediate server, and to form a hierarchical structure for geographic information. And by selecting the geographic information of each layer from the preset content to input all the geographic information for all layers, there is an advantage that can be searched to the lower layer when searching the multimedia content based on geographic information.
