  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings. However, the present invention is not limited to these embodiments. FIG. 1 shows an amplification device 100 to which an Internet radio terminal (content reproduction device) according to a preferred embodiment of the present invention is applied, an Internet radio server (hereinafter simply referred to as a server) 200, and a search engine (also called a search site). ) Is a block diagram showing a connection configuration with 300.

  The server 200 stores a plurality of contents called Internet radio. The content includes music (sound) data, video data, image data, and the like. In this example, the content is music data. Each piece of music data is provided with a location information URL (uniform resource locator) indicating the location on the Internet in order for the amplification device 100 to access and obtain the song data. Note that the term URI is sometimes used as a superordinate concept of URL.

  The server 200 also stores a playlist (content list) that is a list of content information of a plurality of pieces of music data selected from all stored music data. The playlist is also given a URL so that the amplification device 100 can access it and acquire the playlist. The content information includes metadata such as title, artist name, album name, and genre name, content length, release year, and the like. In this example, the content information is a title. FIG. 2 is a diagram illustrating an example of a playlist. In the playlist of FIG. 2, information of nine song data is listed, and URL and title are described for each song data. The part described as “File1 = http: //...” Is the URL, and the part described as “Title =.

  The server 200 returns song data and a playlist to the amplification device 100 in response to a request from the amplification device 100. In addition, a URL and a title related to, for example, one piece of music data in the playlist may be returned to the amplification device 100.

  The server 200 stores the MIME type for each piece of music data stored therein. Details of the MIME type will be described later. The server 200 returns a MIME type to the amplification device 100 in response to a request from the amplification device 100. The MIME type may or may not be included in the playlist. When the MIME type is not included in the playlist, the server 200 returns the MIME type to the amplification device 100 when the amplification device 100 accesses the URL of the song data described in the playlist.

  The amplification device 100 has a function as an Internet radio terminal. The amplifying apparatus 100 accesses a location on the Internet specified by the URL described in the playlist (hereinafter simply referred to as URL), and acquires song data from the server 200 via the Internet in a stream format. And play the acquired song data. In addition, the amplifying apparatus 100 accesses a URL input by a user operation and acquires a playlist from the server 200. Further, the amplifying apparatus 100 accesses the URL of the song data described in the playlist, acquires the MIME type, and registers the MIME type in the MIME type list for each song data.

  When the URL input by the user operation for acquiring the playlist or the song data from the server 200 is an inaccurate URL such as a URL that does not exist on the Internet, the amplification device 200 is set in advance. Based on the URL of the search engine 300 (this URL includes a predetermined keyword used as a search keyword in the search engine 300 (for example, InternetRadio, but may be another keyword)) A search URL including a character string of a URL input by a user operation as a search keyword is generated, and the generated search URL is accessed.

  In the search engine 300, based on (1) a URL input by a user operation and (2) a predetermined keyword included in a search URL accessed from the amplification device 100, these two keywords are used on the Internet. A hyperlink (hereinafter referred to as “link”) to the location of is searched, and a list of links as a search result is returned to the amplification device 200. As a search method in the search engine 300, a known method such as an AND search of two keywords is adopted.

  The amplifying apparatus 100 displays a list of search result links returned from the search engine 300. The search result may include a link to a playlist desired by the user, a link to song data, or a link to another WEB page of the server 200 that holds the playlist or song data. The user can search for a desired playlist from a list of links of search results.

  FIG. 3 is a block diagram showing a configuration of the amplifying apparatus 100. The amplifying apparatus 100 includes a system control unit 2, a storage unit (including ROM, RAM, flash memory, etc.) 3, a reproduction unit 4, an amplification unit 5, an operation unit 6, a display unit 7, and a communication unit 8. And roughly. A general configuration as an amplifying device such as an audio input terminal or a power supply circuit is omitted.

  The system control unit 2 controls the entire amplifying apparatus 100 based on a program stored in the storage unit 3, and is, for example, a microcomputer. The system control unit 2 performs a search including a predetermined keyword when the URL is not accurate, for example, when the description of the URL input by a user operation is incomplete or when a playlist or song data cannot be obtained from the URL. By including the input URL in the URL of the engine 300, a search URL is generated, the search URL is accessed, a list of search result links is acquired from the search engine 300, and displayed on the display unit 7 Let

  In the storage unit 3, the playlist file shown in FIG.

  The storage unit 3 stores a MIME type list shown in FIG. Nothing is initially registered in the MIME type list, and the system control unit 2 registers a MIME type for each index. The MIME type list includes the MIME type of the song data in association with the playlist index stored in the storage unit 3. The index is a character or symbol that serves as a clue to search for target information, and is a serial number (an integer starting from 0) of music data included in the playlist in this example. In this example, the index is assigned by the system control unit 2, but may be assigned in advance by the server 200.

  The MIME type is information indicating the type (format) of a file used in the WEB, and is a character string in the format of “type name / subtype name”. For example, “audio / mp3” indicates an MP3 format music file, and “image / jpeg” indicates a JPEG format image file. That is, a file whose MIME type “type name” is “audio” is music data that can be reproduced by the amplification device 100. Also, the playlist itself shown in FIG. 2 is given a MIME type, and is represented by, for example, “text / pls”, “text / m3u”, or the like. Also, a MIME type is assigned to a normal WEB document (for example, an HTML document or an XML document, hereinafter referred to as an HTML document), and is represented by “text / html”. Although not particularly limited, the registered content of the MIME type list is cleared when the playlist is discarded from the storage unit 3.

  Further, the URL of the search engine 300 is recorded in the storage unit 3. Although the URL of the search engine 300 is set in advance by the manufacturer of the amplification device 100, the URL can be changed by a user operation. The URL of the search engine 300 is set to, for example, “http://www.AAA.com/q=$KEYWORD$+InternetRadio”, and “KEYWORD” includes a URL input by a user operation. The URL of the search engine 300 includes a predetermined keyword, and “InternetRadio” corresponds to the predetermined keyword. The predetermined keyword is also set in advance by the manufacturer of the amplifying apparatus 100, but can be changed by a user operation. "+" Between "KEYWORD" and "InternetRadio" means AND search.

  Returning to FIG. 3, the playback unit 4 accesses the URL of the song data described in the playlist and plays back the song data acquired from the server 200 in, for example, the streaming format (decompression processing or D / A). Including conversion processing). The amplifying unit 5 amplifies the music signal reproduced by the reproducing unit 4 and supplies the music signal to a speaker (not shown).

  The operation unit 6 receives an instruction from the user and transmits it to the system control unit 2, and is an operation button provided on the front panel of the amplifying apparatus 100 or a remote control transceiver. The display unit 7 displays a playlist or the like as shown in FIG. 5, and is an FL tube, an LCD (liquid crystal display), or the like. The display unit 7 may display an OSD (on-screen display) on a display device such as a liquid crystal monitor or a TV receiver connected to the outside. FIG. 5A is a list in which playlists Channel1, Channel2,... Are enumerated as folders. When Channel 1 is selected, a list of song data in the Channel 1 folder is displayed as shown in FIG.

  The communication unit 8 is connected to the server 200 via the Internet and transmits and / or receives various commands, song data, playlists, MIME data, and the like with the server 200, and is a network interface or the like. In addition, the communication unit 300 is connected to the search engine 300 via the Internet, and acquires a list of links searched based on the accessed URL from the search engine 300.

  The operation of the amplifying apparatus 100 having the above configuration will be described. FIG. 6 is a flowchart showing the processing of the system control unit 2 when the URL of the playlist or song data is input by a user operation. In this example, it is assumed that the URL “http://jazz.com” is correctly input by a user operation, but “jazz.com” is input by mistake.

  The system control unit 2 determines whether a URL is input through the operation unit 6 by a user operation (S1). When it is determined that the URL has been input (YES in S1), the system control unit 2 determines whether the input URL is correct, that is, whether the description of the input URL is valid ( S2). Specifically, it is determined whether or not the URL starts with a predetermined character string, for example, “http: //”.

  In this example, since it is determined that the URL does not start from “http: //” (NO in S2), the process proceeds to S6. On the other hand, when it is determined that the URL starts from “http: //” (YES in S2), the system control unit 2 accesses the input URL (S3), and starts from the location specified by the URL. Try to get (playlist or song data). The system control unit 2 determines whether the file has been acquired (S4). For example, if the URL is accessed but cannot be connected, or if the connection is possible but there is no response and the file cannot be acquired (NO in S4), the process similarly proceeds to S6.

  On the other hand, when the file can be acquired in S4 (YES in S4), the system control unit 2 acquires the MIME type related to the acquired file at the same time as the file, and thus the acquired MIME type indicates a playlist. It is determined whether or not “text / pls”, “text / m3u”, or “audio /...” Indicating song data (S5). That is, it is determined whether or not the server 200 has been correctly accessed and a playlist or song data has been acquired from the server 200.

  When it is determined that the MIME type is “text / pls” or “text / m3u” indicating a playlist, or “audio /.” Indicating song data (YES in S5), the system control unit 2 If the MIME type is “text / pls” or “text / m3u”, as shown in FIG. 5A, the acquired playlist is displayed on the display unit 7 (S8). When the MIME type is “audio / ..”, the playback unit 4 plays back the acquired music data. (Note that the process of S5 may be omitted, and the process may always proceed to S8 if YES in S4.)

  On the other hand, if it is determined that the MIME type is not “text / pls”, “text / m3u” indicating a playlist, or “audio /.” Indicating song data (NO in S5), the process proceeds to S6. move on.

  In S6, the system control unit 2 determines whether or not the URL of the search engine 300 is recorded in the storage unit 3 (S6). When the URL of the search engine 300 is not stored (NO in S6), the system control unit 2 displays information on the display unit 7 that the input URL is incorrect and that the playlist and song data cannot be acquired. (S7).

In this example, since the URL of the search engine 300 is stored in the storage unit 3 (YES in S6), the system control unit 2 reads the URL of the search engine 300 recorded in the storage unit 3. Then, the system control unit 2 includes the URL input by the user operation in the URL of the search engine 300, and generates a search URL (S9). Specifically, “http://www.AAA.com/q=$KEYWORD$+InternetRadio” is stored in the storage unit 3 as the URL of the search engine 300, and “jazz.com” is the URL as a user operation. Is entered as the search URL "http://www.AAA.com/q=jazz.com
+ InternetRadio "is generated. In this manner, the URL for search is generated by including the input URL in the “KEYWORD” portion of the URL.

  Subsequently, the system control unit 2 accesses the generated search URL (search engine 300) (S10). When the search engine 300 receives access from the amplification device 100, the search engine 300 is based on the keyword “jazz.com” that is the URL input by the user and the predetermined keyword “InternetRadio” included in the accessed search URL. Search for files on the internet. For example, an AND search of “jazz.com” and “InternetRadio” is executed, but an OR search or other search may be performed. The search engine 300 returns a list of URL links of a plurality of Internet files as search results to the amplification device 100.

  When acquiring the link list from the search engine 300, the system control unit 2 temporarily stores it in the storage unit 3 and causes the display unit 7 to display the link list. FIG. 7 is a diagram showing a list of links displayed on the display unit 7. In FIG. 7, ten links 1 to 10 are displayed, and “JazzAAA” to “JazzJJJ” are displayed as the names of the links. When one link is selected from the list of links by the user operation, the system control unit 2 accesses the URL of the selected link, acquires a file from the URL, and causes the display unit 7 to display the file. . This link is a link to a file associated with “jazz.com” input as the URL of the playlist desired by the user and the predetermined keyword “InternetRadio”. Therefore, there is a high possibility that a link to a playlist or song data desired by the user exists.

  As described above, according to this example, even when an incorrect URL is input by a user operation, a link to a file on the Internet related to the input URL and a predetermined keyword can be displayed. it can.

[Another embodiment 1]
In this example, the storage unit 3 stores a plurality of URLs of the search engine 300. A plurality of URLs of the search engine 300 are stored (1) When a plurality of search engines are used and the predetermined keyword is the same, (2) When one search engine is used and only the predetermined keyword is different, 3) There are cases where there are a plurality of search engines and the predetermined keywords are different. In this example, (1) will be described as an example.

  The system control unit 2 accesses a plurality of search URLs stored in the storage unit 3, acquires a list of links from the plurality of search engines 300, and summarizes the list of these links into one link list. . Even if the keyword is the same, if the search is performed by different search engines 300, the search results of each search engine are different, but the same link may be included. For the same link, the number of appearances (that is, the number of hit search engines) is counted, and when the list of links is displayed on the display unit 7, the number of appearances is displayed and arranged in descending order. Change to display. Search results with a large number of appearances are likely to be hyperlinks to files useful to the user, so displaying them above the list can increase the possibility of finding the desired playlist or song data. .

  FIG. 8 is a flowchart showing processing of the system control unit 2 in this example. Since the process of S1-S8 is the same as FIG. 6, description is abbreviate | omitted. The system control unit 2 selects one URL of the search engine 300 stored in the storage unit 3, and generates a search URL based on the selected URL (S11). The method for generating the search URL is the same as described above.

  When acquiring the list of links from the search engine 300, the system control unit 2 temporarily stores it in the storage unit 3 (S12). Then, the system control unit 2 determines whether or not the processes of S10 and S11 have been executed for the URLs of all the search engines 300 stored in the storage unit 3 (S13). If the processing has not yet been executed for all the search engines 300 (NO in S13), the process returns to S11 to select the URL of the next search engine 300 stored in the storage unit 3, and in S11 and S12 Execute the process. On the other hand, if the process is executed for all the search engines 300 (YES in S13), the process proceeds to S14. That is, a list of links is acquired from the search engines 300 of all URLs stored in the storage unit 3 and stored in the storage unit 3.

  Subsequently, the system control unit 2 collects a list of links acquired from all the search engines 300 whose URLs are stored in the storage unit 3 into one list, and the descending order of the hit search engines 300 (descending order). The links are rearranged (S14). The system control unit 2 displays the rearranged list of links on the display unit 7 as shown in FIG. At this time, the number of hit search engines 300 (number of appearances) is also displayed. FIG. 9 shows that the link “JazzDDD” has been hit by five search engines (that is, search URLs), and is likely to be the most useful URL.

[Another embodiment 2]
In this example, when displaying a list of links of search results, the URL of the link is accessed, the MIME type related to the link is acquired, and if the link is a link to a playlist, the link to the playlist [PLS] and [M3U] are displayed on the left side of the link name. Therefore, the user can easily find a link to the playlist from among a plurality of search result links. If the MIME type of the link is a normal WEB document (for example, an HTML document, an XML document, etc., hereinafter referred to as an HTML document), a lower link described in the HTML document is extracted, Display as the subordinate directory of the link. Therefore, it is possible to directly select the lower link included in the HTML document.

  FIG. 10 is a flowchart showing details of S10 of FIG. The system control unit 2 accesses the URL of the first link “JazzAAA” in the search result shown in FIG. 7 and acquires the MIME type related to the link (S21). The system control unit 2 determines whether the acquired MIME type is “text / pls” or “text / m3u” indicating a playlist (S22). When the MIME type is “text / pls” or “text / m3u” (YES in S22), the system control unit 2 displays [PLS] or [M3U] to the left of the search result link name. Let For example, if the MIME type of the first link “JazzAAA” is “text / pls”, [PLS] is displayed to the left of “JazzAAA” as shown in FIG. Therefore, the user can easily recognize that “JazzAAA” is a link to the playlist.

  Subsequently, the system control unit 2 determines whether or not all search result links have been processed (S28), and since all search result links have not been processed yet (NO in S28), the process returns to S21. Then, the same processing is performed for the second link “JazzBBB” (S21, S22). For example, when the MIME type of the link “JazzBBB” is not “text / pls” or “text / m3u” (NO in S22), the system control unit 2 has “text / html” indicating that the MIME type indicates an HTML document. It is determined whether or not (S24). When the MIME type is not “text / html” (NO in S24), the process proceeds to S28. Here, since the MIME type of the link “JazzBBB” is “text / html” indicating an HTML document (YES in S24), the system control unit 2 accesses the URL of the link “JazzBBB” and acquires the HTML document. (S25).

  Subsequently, the system control unit 2 determines whether or not a lower link is included in the acquired HTML document (S26). A lower link means a link described in an HTML document. If the HTML document does not include a lower link (NO in S26), the process proceeds to S28. Here, since the lower link is included in the HTML document (YES in S26), the system control unit 2 extracts the lower link from the HTML document, and the extracted lower link is linked as shown in FIG. It is displayed as a subordinate directory (also called a hierarchy or folder) of “JazzBBB” (S27). Thereafter, the process proceeds to S28, and when the same process is completed for all links in the search result (YES in S28), the process is terminated.

  Here, the detailed processing of S26 and S27 will be described with reference to the flowchart of FIG. FIG. 13 is a diagram illustrating an example of the acquired HTML document. As shown in FIG. 12, the system control unit 2 searches the HTML document for tags <a> and </a>, and sets a portion surrounded by the tags <a> and </a> as a lower link. Specify (S31). For example, in the case of FIG. 13, two lower links, a lower link shown in (a) and a lower link shown in (b), are included.

  Subsequently, the system control unit 2 specifies the file type from the file name in the lower link included between the tags <a> and </a> (S32). Specifically, since the part starting with “href =” indicates the file name of the lower link, the extension of the character string included therein is checked to determine the file type. Then, the system control unit 2 determines whether or not the file type of the lower link is “pls” or “m3u” indicating a playlist (S33).

  For example, for the link in (a), “filename.pls” is described after “href =”, and the file extension is “pls”, so that the file type is determined to be a playlist. (YES in S33). In this case, the system control unit 2 displays [PLS] indicating that the lower link is a link to the playlist on the first line of the lower directory of the link “JazzBBB” as shown in FIG. 11 (S34). ).

  For example, for the link (b), it is determined that a simple URL is described after “href =”, the extension is not “pls”, and the file type is not a playlist (S33). NO). In this case, as shown in FIG. 11, the system control unit 2 indicates that the lower link is not a link to the playlist but is unknown in the second line of the lower directory of the link “JazzBBB” [? ] Is displayed (S35).

  Subsequently, the system control unit 2 includes a character string that is not a tag (that is, not enclosed in <>) between the tags <a> and </a> (in the lower link). It is determined whether or not (S36).

  For example, for the lower link in (b), a character string “YYYYY” that is not a tag is included between the tags <a> and </a> (YES in S36). Therefore, the system control unit 2 extracts the character string “YYYYY” and, as shown in FIG. ] “YYYYY” is displayed as the name of the lower link on the right side of [].

  For example, for the lower link in (a), a character string that is not a tag is not included between the tags <a> and </a> (NO in S36). Specifically, only the image tag <img...> Is included between the tags <a> and </a>. Therefore, the system control unit 2 confirms whether or not a simple character string that is not a tag is included in an upper hierarchy (also referred to as a table) including the tags <a> and </a> (S38). The level one higher than the tags <a> and </a> is a portion between the tags <td> and </ td>, and the level higher than the tags <tr> and </ tr> The part between.

  For example, a character string that is not a tag is not included in the hierarchy one level higher than the lower link of (a) (the portion between the tags <td> and </ td>). However, a character string “YYYYY” that is not a tag is included in a higher hierarchy (a portion between tags <tr> and </ tr>) (YES in S38). Therefore, the system control unit 2 extracts the character string “YYYYY”, and displays “YYYYY” as the name of the lower link on the right side of [PLS] as shown in FIG. 11 (S39).

  If the upper table (the portion between the tags <tr> and </ tr>) does not include a character string that is not a tag (NO in S38), the system control unit 2 Extracts at least part of the file name included between the tags <a> and </a> (within the lower link) and displays it as the name of the lower link (S40). For example, when the image tag <img...> Is included, a part of the file name in the image tag is preferentially extracted and displayed as the name of the lower link. For example, in the case of the lower link (a), since an image tag is included, a part of the file name “PPP” is extracted and displayed on the display unit 7. If the image tag is not included, a part of the file name in other tags may be extracted and displayed as the name of the lower link.

  Through the above processing, if the search result link is a link to an HTML document, the lower links in the HTML document are further extracted and displayed. Since there is a high possibility that the HTML document includes a lower link to the playlist desired by the user, the desired playlist is accessed by selecting the lower link and accessing the URL assigned to the lower link. Can be displayed. In FIG. 11, since there is a high possibility that the lower links whose link types are displayed as [PLS] or [M3U] are links to the playlist, these lower links are preferentially displayed above the list. It is good to let them.

  Next, a modification of the process of FIG. 12 will be described with reference to the flowchart of FIG. The same processes as those in FIG. 12 are denoted by the same reference numerals, and description thereof is omitted. In S41, the system control unit 2 accesses the URL of the lower link specified in S31, and acquires the MIME type related to the lower link. The acquired MIME type is temporarily stored in the storage unit 3 in association with the lower link. Subsequently, the system control unit 2 determines, for each lower link, whether or not the acquired MIME type is “text / pls” or “text / m3u” indicating a playlist (S42). If the MIME type is “text / pls” or “text / m3u” indicating a playlist (YES in S42), the process proceeds to S34, and the MIME type is “text / pls” or “text / m3u” indicating a playlist. If not (NO in S42), the process proceeds to S35. As described above, by determining and displaying the type of link based on the MIME type, the user can be more surely notified of the playlist link.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment. The present invention may be provided in the form of a computer program for operating the content type registration apparatus or a recording medium on which the computer program is recorded.

  The present invention can be particularly preferably applied to an amplification device, a PC, or the like having an Internet radio function.
