In another embodiment, the recorded file may be in a state in which playback is not started but only selected.

Subsequently, the controller 170 extracts the keyword 146 from the selected recording file 142 and displays it on the display unit 160 (step S12). As described above with reference to FIGS. 1 and 2, the keyword is displayed on the progress display bar corresponding to the recording file according to the generation time and displayed in the form of a keyword bookmark, or the keyword is displayed in the form of a keyword list according to the generation time. Alternatively, the keywords may be freely distributed in the form of a keyword cloud, but the attributes may be displayed differently according to the frequency of occurrence. Such display forms may be applied in combination of two or more, and may be selected by a user.

Subsequently, the controller 170 checks whether a specific keyword is selected from the keywords displayed on the display unit 160 (step S13). 3 described above corresponds to a screen implementation of this step. Referring to FIG. 3, when a user selects a specific keyword 16a through the key input unit 150 from the keyword list 16 displayed on the display unit 160, the controller 170 receives a corresponding signal from the key input unit 150. Receive and recognize the selection of keywords.

Recognizing the selection of a specific keyword, the controller 170 controls the recording file player 172 to pause the recording file being played (step S14). In addition, the controller 170 determines whether to search for related information of the selected keyword (S15). To this end, the controller 170 may display a list of subsequent options on the display unit 160. Referring again to FIG. 3, when a specific keyword 16a is selected in the keyword list 16, the controller displays a subsequent option list 20 in the form of a popup window.

If the keyword related information is not searched, the controller 170 performs another function (step S16). For example, as illustrated in FIG. 3, when the subsequent option list 20 includes an option of 'play at the keyword selection position' and the user selects it, the controller 170 controls the recording file player 172. Play the recorded file at the time of occurrence of the keyword (ie, at the time of recording).

As a result of the determination in step S15, in the case of searching for keyword related information, the controller 170 controls the communication interface 180 to access the search server 300 through the network 200 (step S17). That is, the example of FIG. 3 corresponds to a case in which the user selects 'keyword related information search' among the subsequent option lists 20. Since a method for implementing a connection between the mobile device 100 and the search server 300 through the network 200 is well known, a detailed description thereof will be omitted.

Subsequently, the controller 170 transmits the selected specific keyword to the search server 300 (step S18). That is, the keyword that the user wants to obtain related information is provided to the search server 300 as a search query. The search server 300 receiving the search query performs a search related to the keyword and returns the related information search result to the mobile device 100. Since the search server 300 and the search process are well known technologies, detailed descriptions thereof will be omitted.

Subsequently, the controller 170 receives a search result from the search server 300 and displays it on the display unit 160 (step S19). 4 described above corresponds to a screen implementation of this step. Referring to FIG. 4, the search result 34 includes text data, image data, audio data, video data, and the like, which are different data types 32, which are classified according to these types and displayed on the screen of the display unit 160. . In addition, a button 33 for using the hide / expand function for each data type 32 is shown. However, the screen implementation of FIG. 4 is just an example for clarity, and the present invention is not limited thereto.

On the other hand, the search result 34 may be a title or description that delivers the summarized content, a web page containing the content, or a URL thereof. In this case, when the user selects a specific search result, a subsequent process such as displaying more detailed information or accessing the corresponding web page is performed.

In the above-described embodiment, the mobile device transmits the search keyword to the search server and receives the search result only after the user selects the specific keyword. However, the method for obtaining keyword related information of the present invention may be different from the above-described embodiment, which will be described below.

7 is a flowchart illustrating a method of obtaining keyword related information of a recorded file according to another embodiment of the present invention.

5 and 7, first, the controller 170 determines whether the recording file generation is completed (step S21). That is, when the recording file 142 is generated by the recording file generator 171 and the selection of the keyword 146 is completed, the controller 170 recognizes this.

Subsequently, the controller 170 controls the communication interface 180 to access the search server 300 through the network 200 (step S21). This step is the same as step S17 in the above-described embodiment, and thus description thereof is omitted.

Subsequently, the controller 170 transmits the keyword inserted into the recording file 142 to the search server 300 (step S23). This step corresponds to step S18 of the above-described embodiment, but step S18 is to transmit the keyword selected by the user, while step S23 provides all the keywords inserted in the recording file to the search server 300 as a search query. There is a difference. The search server 300 receiving the search query performs a search related to the keyword and returns the related information search result to the mobile device 100.

The control unit 170 receives the search result 148 from the search server 300 and stores it in the storage unit 140 (step S24). That is, before the user selects a specific keyword to obtain related information, the storage 140 stores the related information search results 148 for all the keywords 146 already.

Subsequently, the controller 170 determines whether a specific recording file is selected from the one or more recording files 142 stored in the storage 140 (S25). Since this step corresponds to step S11 of the above-described embodiment, a detailed description thereof will be omitted.

When a specific recording file is selected, the controller 170 extracts the keyword 146 from the selected recording file 142 and displays it on the display unit 160 (step S26). Since this step corresponds to step S12 of the above-described embodiment, a detailed description thereof will be omitted.

Subsequently, the controller 170 checks whether a specific keyword is selected from the keywords displayed on the display unit 160 (step S27). Since this step corresponds to step S13 of the above-described embodiment, a detailed description thereof will be omitted.

When a specific keyword is selected, the controller 170 extracts the relevant information search result 148 for the selected keyword from the storage 140 and displays it on the display unit 160 (step S28). That is, as in the above-described embodiment, the search result 148 may be extracted and displayed directly from the storage 140 without going through a process of accessing a search server, transmitting a keyword, and receiving a search result.
