Description

  The present invention relates to an electronic device and a data generation method capable of generating data having a hierarchical structure.

  With the recent rapid development of digital technology and network technology, contents such as music, photos, and moving images are being digitized and being searched and browsed on a network such as the Internet. For example, in Flicker, which is an Internet site, a large amount of image data is stored, and image data is searched and viewed by a large number of users.

  On the other hand, with the advancement of home network technology, home digital content distribution technology is becoming common. For example, using a digital TV, DMS (Digital Media Server), or printer that complies with the standard specifications of DLNA (Digital Living Network Alliance), you can view digital photos stored in your home on a digital TV and print them with a printer. Etc. have been proposed.

  The problem here is that there is a large gap between the two content management methods, and it is difficult to connect them. Specifically, the former tends to manage content using an identification name for the content (for example, a character string arbitrarily given by a user such as a flower, a hobby, or a cactus) in order to handle an unspecified large amount of content. . The latter is specified in the specification to manage content using a hierarchical directory having a tree structure.

  As a technique for solving such a problem, it is conceivable to automatically hierarchize identification names used in the search. For example, Japanese Patent Laid-Open No. 2002-189740 describes a data conversion system in which an HTML document is hierarchized based on a certain hierarchization rule and rearranged into data that is meaningful based on the conversion rule.

Japanese Patent Application Laid-Open No. 9-284571 describes an electronic newspaper system in which input articles are hierarchically structured and related symbols are added to those that are interrelated.
JP 2002-189740 A Japanese Patent Laid-Open No. 9-284571

  However, the technique disclosed in Japanese Patent Laid-Open No. 2002-189740 is a hierarchization based on tag names described in a sentence, and is not a hierarchization technique according to the meaning content of an identification name. Further, in the technique of Japanese Patent Laid-Open No. 9-284571, it is described that hierarchization is performed in a tree structure, but a specific technique for hierarchization is not described, and the hierarchical structure is classified into fields, major classifications. It is fixed like middle classification and small classification and cannot be hierarchized flexibly.

  An object of the present invention is to provide an electronic device and a data generation method capable of generating data that is searchable for content with a defined identification name and that is more flexible in hierarchical structure. There is to do.

In order to solve the above problems, an electronic device according to the present invention is
An input unit for inputting content data in which at least one identification name is defined for each content;
A storage unit that stores correspondence between the identification name and the hierarchy name, and stores hierarchy construction dictionary data indicating an upper hierarchy and a lower hierarchy of the hierarchy for each hierarchy name;
Data generation for generating the hierarchical data indicating the upper and lower layers of the hierarchy of the hierarchy name, with the identification name defined as the hierarchy name based on the content data and the hierarchy construction dictionary data And
Including
The data generation unit may define the identification name as the hierarchy name when the identification name of the content data does not match the hierarchy name of the hierarchy construction dictionary data.

The data generation method according to the present invention includes:
In a data generation method in an electronic device having an input unit, a storage unit that stores dictionary data for hierarchy construction, and a data generation unit,
The hierarchy construction dictionary data indicates an association between an identification name and a hierarchy name, and indicates an upper hierarchy and a lower hierarchy of the hierarchy for each hierarchy name,
The input unit inputs content data in which at least one identification name is defined for each content,
The data generation unit, based on the content data and the hierarchy construction dictionary data, if the identification name of the content data does not match the hierarchy name of the hierarchy construction dictionary data, the identification name By defining as a hierarchy name, the identification name is defined as the hierarchy name, and hierarchical data indicating an upper hierarchy and a lower hierarchy of the hierarchy of the hierarchy name is generated.

  According to the present invention, the electronic device inputs data in which the identification name is defined, and uses the hierarchical construction dictionary data to define the identification name as the hierarchical name, and Hierarchical data indicating the upper hierarchy and lower hierarchy of the hierarchy of the hierarchy name can be generated.

  In addition, according to the present invention, even when the identification name does not match the hierarchy name of the hierarchy construction dictionary data, the electronic device handles the identification name as one of the hierarchies by defining it as a new hierarchy. be able to.

  Thereby, the electronic device can generate the hierarchical data in a state where the identification names are hierarchized more flexibly, and can search for the content in which the identification names are defined.

  In addition, when the data generation unit generates the hierarchical data, if the identification name of the content data partially matches the hierarchical name of the hierarchy construction dictionary data, the data generation unit converts the hierarchy and the hierarchy into an upper hierarchy. A hierarchy in which the identification name is defined as the hierarchy name may be added to the hierarchical data.

  According to this, even when the identification name is expressed by a low-level concept term or a non-standard term, the electronic device has a hierarchical data with a high-level concept term or a standard term. Can be provided. Accordingly, the user can find a hierarchy having an identification name from the hierarchy of terms of higher concepts or standard terms, and the electronic device can improve the ease of searching.

  The data generation unit may associate data indicating the location of the content with a hierarchy of the hierarchy name that matches the identification name when generating the hierarchical data.

  According to this, the electronic device can grasp the location of the content from the hierarchy having the identification name, and can provide information indicating the location of the content to the external device.

The content data is data stored in a server connected to the Internet,
The input unit may input the content data by receiving the content data via the Internet.

  According to this, the electronic apparatus can acquire content data via the Internet and generate hierarchical data. In particular, data that exists on the Internet is given arbitrary identification names by various users, but an electronic device can generate hierarchical data that can be searched even for content with arbitrary identification names. it can.

In addition, the electronic device is
A receiving unit that indicates an acquisition request for desired content from an external device, and that receives request information in which the hierarchical name is specified;
A search unit that searches for the desired content from the hierarchical data based on the request information;
A transmission unit that transmits the desired content searched by the search unit to the external device;
May be included.

  According to this, the electronic device can search and provide desired content from the hierarchical data in response to a request from the external device.

Further, the request information is information indicating a movement operation between hierarchies or a movement operation from a hierarchy to content in the hierarchical data,
The search unit may search for the desired content by changing information indicating a search target in accordance with the moving operation.

  According to this, the electronic device can search for content according to the moving operation. As a result, the user can search for the desired content only by using the cursor key (arrow key) of the electronic device body or the moving operation using the remote controller (remote controller) without inputting the identification name using a keyboard or the like. Can do.

  Hereinafter, a case where the present invention is applied to a printer having a communication function will be described as an example with reference to the drawings. In addition, the Example shown below does not limit the content of the invention described in the claim at all. In addition, all of the configurations shown in the following embodiments are not necessarily essential as means for solving the problems described in the claims.

(Description of the entire system)
FIG. 1 is a schematic diagram of content data 210 in the present embodiment. FIG. 2 is a schematic diagram of the hierarchical data 126 in the present embodiment.

  The content data 210 is stored in a server connected to the Internet, and a user accesses the Internet using a PC (Personal Computer) or the like and designates an identification name (sometimes called a “tag”). A search is performed, and desired content is reproduced from content that matches the identification name.

  As described above, in the Internet contents, hierarchical classification is not performed, and a free identification name is often given by the user. This is because the user can input characters relatively easily using the keyboard of the PC.

  On the other hand, electronic devices such as printers and TVs are not equipped with a keyboard, and the user selects the desired content using the cursor keys (arrow keys) and remote control (remote controller) of the electronic device body. There is a need.

  In this embodiment, the content data 210 is input and the hierarchical data 126 is generated, thereby realizing a printer that can easily search for the target content even when the remote controller is used. Next, functional blocks of a printer having such a function will be described.

  FIG. 3 is a diagram illustrating an example of functional blocks of the printer 100 according to the present exemplary embodiment.

  The printer 100, which is a type of electronic device, includes an input unit 110 that inputs content data 210 from the server 200 via the Internet 300, a storage unit 120 that stores various data, and data generation that generates hierarchical data 126. Unit 130, image generation unit 140 that generates search images and the like, output unit 150 that outputs various images, reception unit 160 that receives request information and the like from TV 400 that is a kind of external device, and an image directed to TV 400 A transmission unit 170 that transmits information and the like and a search unit 180 are included.

  The output unit 150 includes a printing unit 152 that prints an image generated by the image generation unit 140.

  The storage unit 120 also stores content data 124 input by the input unit 110, hierarchical data 126 generated by the data generation unit 130, hierarchical construction dictionary data 122 used to generate the hierarchical data 126, and the like. I remember it.

  Here, the hierarchy construction dictionary data 122 will be described in more detail. FIG. 4 is a diagram illustrating an example of the hierarchy construction dictionary data 122 in the present embodiment.

  The items of the hierarchy construction dictionary data 122 include, for example, “the number of stages” indicating the position in the vertical direction of the hierarchy, “hierarchy name” indicating the target hierarchy, “higher hierarchy name” indicating the hierarchy immediately above the target hierarchy, Examples include “lower hierarchy name” indicating a hierarchy immediately below the target hierarchy, “identification name” indicating an identification name corresponding to the target hierarchy, and the like. As described above, in the hierarchy construction dictionary data 122, the identification name and the hierarchy name are associated with each other, and the upper hierarchy and the lower hierarchy of the hierarchy are defined for each hierarchy name.

  Note that * in the “identification name” indicates a character string of zero or more characters. That is, for example, “* travel” corresponds to “Africa travel”, “school excursion”, and the like. “NULL” indicates no value.

  Specifically, for example, in the hierarchy “root”, “stage number” is “0”, “hierarchy name” is “root”, “upper hierarchy name” is “NULL”, and “lower hierarchy name” is “favorite, travel” Etc. ”and“ identification name ”are“ NULL ”. Further, for example, in the hierarchy “travel”, the “stage number” is “1”, the “hierarchy name” is “travel”, the “upper hierarchy name” is “route”, and the “lower hierarchy name” is “hot spring, travel to Africa, etc.” The “identification name” is “* travel etc.”.

  Next, the hierarchical data 126 will be described in more detail. FIG. 5 is a diagram illustrating an example of the hierarchical data 126 in the present embodiment.

  The items of the hierarchical data 126 include, for example, “the number of stages” indicating the position in the vertical direction of the hierarchy, “hierarchy name” indicating the target hierarchy, “higher hierarchy name” indicating the hierarchy immediately above the target hierarchy, and the target hierarchy “Lower level name” indicating the level immediately below, “Link” indicating the link of the content associated with the target level, and the like. Thus, in the hierarchized data 126, the identification name is defined as the hierarchy name, and the upper hierarchy and the lower hierarchy of the hierarchy of the hierarchy name are defined.

  The “link” corresponds to, for example, content identification information, an address indicating a content storage location, or the like. The “link” may be the content itself. In order to make the explanation easy to understand, in this embodiment, the identification name of the content is used as the “link”.

  For example, when the hierarchized data 126 has the hierarchical structure shown in FIG. 2, the “travel” of the hierarchy “travel” is “1”, the “hierarchy name” is “travel”, and the “upper hierarchy name” is “route”. ”,“ Lower level name ”is“ Hot spring, African travel ”, and“ Link ”is“ NULL ”. Further, in this case, the hierarchy “Africa travel” has “stage number” of “2”, “hierarchy name” of “Africa travel”, “upper hierarchy name” of “travel”, “lower hierarchy name” of “NULL”, The “link” is “DSC10406.JPG, DSC10407.JPG, DSC10408.JPG”.

  Note that the functions of each unit such as the input unit 110 may be implemented in the printer 100 using the following hardware, for example. For example, the input unit 110, the reception unit 160, and the transmission unit 170 are a LAN card, the storage unit 120 is a RAM, an HDD, the data generation unit 130, the search unit 180 is a CPU, and the image generation unit 140 is an image. An ink, an ink head, or the like may be used as the processing unit or the printing unit 152.

  Further, any hardware can be employed as the hardware of the input unit 110, the reception unit 160, and the transmission unit 170 according to the applied network, communication method, protocol, and the like. The input unit 110, the reception unit 160, and the transmission Unit 170 may be integrated hardware, or each may be separate hardware.

(Explanation of the flow of hierarchical structure processing)
Next, the flow of hierarchical structuring processing until the printer 100 inputs the content data 210 and generates the hierarchical data 126 will be described. FIG. 6 is a flowchart illustrating an example of the flow of the hierarchical structuring process in the present embodiment.

  Here, as shown in FIG. 1, it is assumed that the printer 100 inputs four still image data (all data shown in FIG. 1) of the content data 210. First, the input unit 110 inputs content data 210 from the server 200 for each content, and stores it as content data 124 in the storage unit 120 (step S1).

  The data generation unit 130 determines whether there is an unprocessed identification name in the newly stored content data 124 (step S2). When there is an unprocessed identification name, the data generation unit 130 determines whether the identification name is not in the hierarchy of the hierarchical data 126 (step S3).

  Then, when the identification name is not in the hierarchy of the hierarchized data 126, the data generation unit 130 determines whether the identification name matches (completely matches) the hierarchy name of the hierarchy construction dictionary data 122 (step S4). ). For example, when the identification name is “favorite”, it matches the hierarchy name of the hierarchy construction dictionary data 122, and when the identification name is “friend A”, it does not match the hierarchy name of the hierarchy construction dictionary data 122.

  When the identification name matches the hierarchy name of the hierarchy construction dictionary data 122, the data generation unit 130 stores the hierarchical data 126 in the hierarchy and the upper hierarchy of the hierarchy based on the hierarchy construction dictionary data 122. A hierarchy that does not exist is added to the hierarchical data 126 (step S5). For example, when the identification name is “favorite” and this is the first process, the data generation unit 130 adds the hierarchy “root” and the hierarchy “favorite” to the hierarchical data 126. The data generation unit 130 also adds “DSC00001.JPG” as the “link” when adding the hierarchy “favorite”.

  Further, when the target identification name does not match the hierarchy name of the hierarchy construction dictionary data 122, the data generation unit 130 determines whether or not the identification name matches the identification name of the hierarchy construction dictionary data 122 (step). S6). In addition, when * is included in the identification name of the dictionary data 122 for hierarchy construction, the case of partial match (forward match, partial match, and backward match) is also determined as a match.

  When the identification name matches the identification name of the hierarchy construction dictionary data 122, the data generation unit 130 adds the hierarchical data 126 to the hierarchical data 126 out of the matched hierarchy and the upper hierarchy of the hierarchy based on the hierarchy construction dictionary data 122. A hierarchy that does not exist is added to the hierarchized data 126, and a hierarchy with the target identification name as the hierarchy name is added to the hierarchized data 126 (step S7). For example, when the identification name is “friend A”, the hierarchy “root” is in the hierarchized data 126, and the hierarchy “person” is not in the hierarchized data 126, the data generation unit 130 determines that the hierarchy “person” and the hierarchy “Friend A” is added to the hierarchical data 126. The data generation unit 130 also adds “DSC10407.JPG, DSC10408.JPG” as “link” when adding the hierarchy “friend A”.

  If the target identification name does not match the hierarchy name of the hierarchy construction dictionary data 122 and does not match the identification name of the hierarchy construction dictionary data 122, the data generation unit 130, based on the hierarchy construction dictionary data 122, If the layer “other” is not in the layered data 126, the layer “other” is added to the layered data 126, and the layer having the target identification name as the layer name is arranged under the layer “other”. It adds to the conversion data 126 (step S8).

  In addition, when the target identification name is in the hierarchy of the hierarchical data 126 in the determination in step S3 described above, the data generation unit 130 determines whether the content identified by the identification name is not in the link of the hierarchical data 126. Is determined (step S9).

  Then, when the content is not in the link of the hierarchical data 126, the data generation unit 130 updates the link of the hierarchical level of the hierarchical data 126 (Step S10).

  Specifically, for example, when processing the content data 210 shown in FIG. 1 in order, the identification name “favorite” in the second content has been added to the hierarchical data 126 as a hierarchy, but the hierarchical data The “link” of the hierarchy “favorite” 126 is only “DSC00001.JPG”. In this case, the data generation unit 130 adds “DSC10406.JPG” to the “link” of the hierarchy “favorite”.

  The printer 100 repeatedly executes the above processing (steps S1 to S10) until there is no uninput content data 210 (step S11).

  With the above procedure, the printer 100 can input the content data 210 and generate the hierarchical data 126 shown in FIG.

(Explanation of search process flow)
Next, a case where the user reproduces desired content stored in the printer 100 by operating the remote controller of the TV 400 will be described. FIG. 7 is a flowchart showing an example of the flow of search processing in the present embodiment.

  The data generation unit 130 determines whether there is a search request from the TV 400 based on the information from the reception unit 160 (step S21).

  When the data generation unit 130 determines that there is a search request, the image generation unit 140 generates image information for displaying the search image based on the hierarchical data 126, and the transmission unit 170 stores the image information. Transmitting to the TV 400 (step S22).

  FIG. 8 is a diagram illustrating an example of transition of search images 500 to 504 in the present embodiment. For example, the image generation unit 140 generates image information for displaying a search image 500 indicating a hierarchy name of a hierarchy having the number of stages of the hierarchical data 126 as the first search image. Each search image 500 to 504 can be moved to another level on the same level by the up and down keys of the remote control, can be moved up one level by the left key of the remote control, and can be moved down one level by the right key of the remote control. Or you can move to the content.

  Based on the information from the receiving unit 160, the search unit 180 determines whether or not there has been a hierarchy designation operation indicating movement between hierarchies (step S23). When there is a hierarchy designation operation, the image generation unit 140 generates image information for displaying the search image moved in the hierarchy in accordance with the operation, and the transmission unit 170 transmits the image information to the TV 400 ( Step S24).

  For example, when the user presses the right key on the remote controller while the search image 500 is displayed and the cursor is on “travel”, the search image 502 with “Africa travel” selected is displayed. Note that “*” in the search images 500 and 502 means that there is content. For example, if “favorite *” is displayed, an outline of the content is displayed if the right key of the remote controller is pressed while “favorite *” is selected.

  Then, the data generation unit 130 determines whether the content is determined based on information from the reception unit 160 (step S25). For example, when the search image 504 showing the outline of the content is displayed and the cursor is at the position “DSC10407.JPG” and the enter key is pressed, the content is determined to be “DSC10407.JPG”. . For easy understanding, the content in the search image 504 is indicated by a name, but the image generation unit 140 may indicate the content by a thumbnail image.

  In the case of content determination, the image generation unit 140 generates image information for displaying the determined content (still image), and the transmission unit 170 transmits the image information to the TV 400 (step S26). Thereby, the TV 400 can display a still image based on the image information.

  The printer 100 repeatedly executes the above processing (steps S21 to S26) until the operation ends (step S27).

  As described above, according to the present exemplary embodiment, the printer 100 inputs data in which an identification name is defined, and uses the hierarchical construction dictionary data 122 to make the identification name a hierarchical name. The hierarchized data 126 that is defined and indicates the upper hierarchy and the lower hierarchy of the hierarchy of the hierarchy name can be generated. In particular, according to this embodiment, the printer 100 can dynamically generate the hierarchical data 126 to connect the upper and lower hierarchies without setting the classification in advance, and the new identification name is also a new hierarchy. As well as links to content.

  Therefore, according to the present embodiment, the printer 100 can flexibly configure the hierarchical data 126 even if the data does not have a hierarchical structure such as the content data 210 stored in the server 200 connected to the Internet 300. It is also possible to search for content with an identification name defined.

  Further, according to the present embodiment, the printer 100 can determine partial match using * as the identification name of the hierarchy construction dictionary data 122, and define a hierarchy in which the partially matched hierarchy is an upper hierarchy. Therefore, even if the identification name is expressed in terms of lower-level concepts or non-standard terms, the hierarchical data 126 can be provided with a higher level of terms of higher-level concepts or standard terms. it can. Accordingly, the user can find a hierarchy having an identification name from the hierarchy of terms of higher concepts or standard terms, and the printer 100 can improve the ease of searching.

  Further, according to the present embodiment, the printer 100 can be used only by operating the cursor key and the up / down / left / right key operations of the remote control without specifying the identification name even when the content search request is received from the TV 400 or the like. Since the hierarchical data 126 can be searched by moving between and the content can be moved from the hierarchy to the content, the desired content can be provided to the search source. As a result, the printer 100 can provide content with an identification name defined for a device that supports only the DLNA environment, such as the TV 400, and can perform a search that is highly convenient for the user.

(Description of other embodiments)
In addition, application of this invention is not limited to the Example mentioned above, A various deformation | transformation is possible.

  For example, the content may not be stored in the storage unit 120. That is, the “link” of the hierarchical data 126 may indicate a storage location of content in the content data 210 in the server 200. Further, the processing time point when the content data 210 is input and converted into the hierarchical data 126 may be, for example, a time point when a content search request is made.

  In the above-described embodiment, the operation is performed using the remote controller of the TV 400. However, the printer 100 performs a search image 500 in accordance with an operation of a cursor key provided on the TV 400 main body or a cursor key provided on the printer 100 main body. Generation of image information for displaying ˜504 may be performed.

  Further, the network through which the input unit 110, the reception unit 160, and the transmission unit 170 input and output information is not limited to the Internet 300 or a home network. For example, the input unit 110 may input content data stored in a mobile phone by wireless communication using Bluetooth.

  The printer 100 may allow the user to edit the hierarchy construction dictionary data 122. According to this, the user can add or change a hierarchy name or an identification name according to his / her usage environment, and associate with an upper or lower hierarchy.

  In addition, the image generation unit 140 may generate a search image or the like by rearranging the hierarchies according to the use frequency, priority, popularity, similarity, etc. of the hierarchy names. According to this, for example, the search unit 180 counts the number of times the movement operation to the lower layer and the movement operation to the content are performed for each layer, and the image generation unit 140 determines the usage frequency based on the number of times. By generating a search image in which hierarchies are arranged from high hierarchy names, the printer 100 can improve the search efficiency of the user.

  Further, the printer 100 may determine content according to an operation button of the printer 100 and print the determined content using the printing unit 152. The content is not limited to still image data, and may be, for example, moving image data, audio data, a program, character data, numerical data, or the like.

  In addition to the printer 100, various devices using images and sounds such as a TV 400, a photo storage device, a projector, a DVD recorder, a portable music player, a game device, and a mobile phone can be adopted as the electronic device. Further, the external device is not limited to the TV 400, and various devices using images and sounds such as a printer, a photo storage device, a projector, a DVD recorder, a portable music player, a game device, and a mobile phone can be employed.

  The functions of the input unit 110 and the like may be distributed and implemented in a plurality of electronic devices. For example, the input unit 110, the storage unit 120, the data generation unit 130, the image generation unit 140, the reception unit 160, and the transmission unit 170 may be provided in the DVD recorder, and the output unit 150 having a display function may be provided in the TV.
