Title information acquisition means (for example, EPG data acquisition unit 101 in FIG. 2) for acquiring information (eg, EPG title data) related to the title of the content included, and the title of the content acquired by the title information acquisition means Information unit related to the titles of the plurality of contents respectively divided by the title information dividing unit (for example, the group dividing unit 102 in FIG. 2) and the title information dividing unit. Unit information extraction that compares information and extracts the same unit information Unit information that has not been extracted by the unit information extraction unit among unit information of information related to the titles of the plurality of contents divided by means (for example, the aggregation unit 103 in FIG. 2) and the title information division unit Based on the identification information setting means (for example, the content title setting unit 104 in FIG. 2) for setting the identification information of each of the plurality of contents, and the same unit information extracted by the unit information extraction means, Presenting means for presenting the identification information of a plurality of contents corresponding to information on titles of a plurality of contents in association with the same unit information, and the unit information extracting means includes the same unit information, The extraction means generates a folder of the identification information corresponding to each hierarchy, and creates a folder of the lower hierarchy. The identification information of a plurality of contents corresponding to information related to content titles is aggregated in the folder, and a user selects a folder in a predetermined hierarchy, and a list of contents or subordinate folders aggregated in the folder When all the contents aggregated in the lower folder are deleted, the lower folder is deleted, and the identification information setting unit includes unit information of information related to the title of one content. Unit information not included in the unit information of the information related to the titles of other contents is set as the identification information of the contents .

  In the data processing device, when the identification information setting unit satisfies unit condition information that is not included in the unit information of the information related to the title of the other content among the unit information of the information related to the title of the one content ( For example, when there is no content, the identification information of the content can be set based on information (for example, detailed information) other than the information related to the title of the content included in the metadata.

A data processing method according to an aspect of the present invention is a data processing method of a data processing apparatus that sets identification information for identifying each of the contents based on metadata added to each of a plurality of contents. Each piece of information (for example, EPG title data) related to the title of the content included in the data is acquired (for example, the processing in step S101 and step S102 in FIG. 3). Each of the unit information is divided into unit information (for example, the process of step S103 in FIG. 3), the unit information of the divided pieces of information relating to the titles of the contents is compared, and the same unit information is extracted (for example, FIG. 3 in step S104), the divided pieces of the content are tight. Based on the unit information that has not been extracted among the unit information of the information related to the information, the identification information of each of the plurality of contents is set (for example, the processing in steps S201 to S209 in FIG. 11), and the extracted Including the step of presenting the identification information of a plurality of contents corresponding to information on the titles of a plurality of contents including the same unit information in association with the same unit information, wherein the same unit information is hierarchized And a folder of the identification information corresponding to each of the layers is generated, and the identification information of a plurality of contents corresponding to information related to the titles of the contents of the lower layers is aggregated in the folder, and the user Selects a folder in a given hierarchy, and the contents consolidated in that folder or If you are viewing the list of folders, when the content that has been aggregated to the lower of the folder is deleted all, the lower of the folder is deleted, of the unit information of the information about the title of one of content, other content Unit information not included in the unit information of the information related to the title is set as the identification information of the content .

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration example of a content recording system 10 according to an embodiment of the present invention. As shown in FIG. 1, the content recording system 10 includes a data processing device 11 that processes content data, a television receiver 12 connected to the data processing device 11, and a printer 13.

  The data processing apparatus 11 is configured as, for example, an HDD (Hard Disk Drive) recorder, and has a tuner 51, a controller 52, and an HDD 53 therein.

  For example, the tuner 51 receives broadcast content via an antenna and supplies the received content to the controller 52 as data. For example, the tuner 51 receives an EPG (Electronic Program Guide) broadcast together with the content, and supplies the received EPG as data to the controller 52.

  The controller 52 decodes the data of the content supplied from the tuner 51 and encoded by a predetermined compression encoding method such as MPEG, for example, into the data decoded by the television receiver 12. A corresponding image or audio signal is output. The controller 52 records data supplied from the tuner 51 on the HDD 53 as necessary.

  Further, the controller 52 is adapted to read and decode the content data recorded in the HDD 53 based on, for example, a user command via a remote commander (not shown).

  In other words, the data processing device 11 is configured to record content and to reproduce the recorded content based on, for example, a user command via a remote commander (not shown).

  Then, the controller 52 displays a list of content titles for specifying the content to be reproduced on the screen of the television receiver 12 or the like, for example, when the user instructs the reproduction of the content. It is designed to generate data.

  In the data processing apparatus 11, a DVD (Digital Versatile Disk) or the like may be used instead of the HDD 53 as a recording medium for recording data. Alternatively, in the data processing device 11, the content recorded on the HDD 53 may be copied or moved to a DVD.

  The controller 52 has, for example, a configuration including a processor, a memory, and the like, and executes predetermined software by executing software such as a preinstalled program.

  Here, it has been described that the television receiver 12 and the printer 13 are connected to the data processing device 11, but the data processing device 11, the television receiver 12, and the printer 13 are DLNA (Digital Living Network Alliance). The data processing apparatus 11, the television receiver 12, and the printer 13 installed at remote locations via the Internet or the like may be connected to each other. Also good.

  Alternatively, the data processing device 11, the television receiver 12, and the printer 13 may be integrated and configured as the data processing device 11.

  FIG. 2 is a block diagram illustrating a functional configuration example of software executed by the controller 52.

  In the figure, an EPG data acquisition unit 101 acquires EPG data of content to be recorded on the HDD 53 for recording. As described above, EPG data is received by the tuner 51 and supplied to the controller 52. The control unit 105 is configured to store the EPG data supplied from the tuner 51 in, for example, a predetermined storage area of the HDD 53 in association with information specifying the content.

  The EPG data acquisition unit 101 specifies and acquires EPG data of content to be recorded, for example. Then, data in an area in the EPG in which information representing the title of the content is stored is supplied to the group dividing unit 102 via the control unit 105 as EPG title data.

  The group division unit 102 groups the EPG title data supplied via the control unit 105 as will be described later.

  The group division unit 102 includes, for example, a morpheme analysis unit 121 that converts EPG title data into text data and performs morphological analysis, and the morpheme analysis unit 121 is included in the text data of the EPG title data. The character string is divided into each morpheme and output to the keyword detection unit 122.

  The keyword detection unit 122 of the group division unit 102 detects a keyword, for example, by comparing each morpheme supplied from the morpheme analysis unit 121 or a word composed of continuous morphemes with preset dictionary data or the like. . Here, the keyword is, for example, a word suitable for analyzing the title of content, and is registered in advance as dictionary data. The keyword detection unit 122 detects, as a keyword, a word that includes each morpheme or a continuous morpheme and matches a word registered in the dictionary data, and includes information indicating the part of speech of the keyword and the control unit 105. Output to.

  Then, a group including one or a plurality of keywords is generated, and EPG title data divided into groups is generated.

  The control unit 105, for example, each title data of a plurality of contents recorded in the internal memory of the controller 52 or a storage unit such as the HDD 53, and the EPG title data grouped by the group dividing unit 102, respectively. It is made to memorize.

  The aggregating unit 103 aggregates the EPG title data of each of a plurality of recorded contents and grouped by the group dividing unit 102 as described later. Thereby, common portions in the EPG titles of a plurality of contents are collected as a folder.

  For example, the content title setting unit 104 sets EPG title data of a portion other than the portion aggregated by the aggregation unit 103 as content title data for each of a plurality of recorded contents. The content title data is, for example, a title that is set so that each of a plurality of contents having overlapping titles in the EPG, such as continuously broadcast content, can be easily identified. For example, the content title setting unit 104 uses the difference data of the EPG title data of each content as the content title data.

  In addition, the content title setting unit 104 sends, via the control unit 105, data in an area other than the area in which information representing the title of the content is stored in the EPG data acquired by the EPG data acquisition unit 101, for example. A predetermined number of character strings obtained from the acquired data are used as content title data. For example, when there is no difference data of EPG title data of each content, the content title setting unit 104 determines the content title based on the data in the area other than the area in which the information indicating the title of the content is stored as described above. Set the data.

  The control unit 105 stores data necessary for the processing of each of the EPG data acquisition unit 101 to the content title setting unit 104, for example, in a memory inside the controller 52 or a storage unit such as the HDD 53, Alternatively, it is read from the storage unit. In addition, the control unit 105 is configured to set and output control signals and the like necessary for controlling each unit of the data processing apparatus 11 as necessary.

  Next, an example of title aggregation processing by the data processing apparatus 11 will be described with reference to the flowchart of FIG. This process may be executed, for example, when content is recorded, or may be executed when a predetermined number of contents are recorded on the HDD 53. Alternatively, it may be executed at a predetermined timing based on a user command or the like.

  In step S101, the EPG data acquisition unit 101 acquires EPG data of content to be recorded in the HDD 53 for recording. At this time, as described above, EPG data received by the tuner 51 and supplied to the controller 52 is acquired. The EPG data acquisition unit 101 specifies and acquires EPG data of content to be recorded, for example.

  In step S102, the EPG data acquisition unit 101 extracts, as EPG title data, data in an area in which information representing the title of the content is stored in the EPG, and the EPG title data is sent to the control unit 105. To the group dividing unit 102.

  In step S103, the group division unit 102 executes group division processing to be described later with reference to the flowchart of FIG. 4 based on the EPG title data extracted in step S102.

  Here, a detailed example of the group division processing in step S103 in FIG. 3 will be described with reference to the flowchart in FIG.

  In step S121, the morphological analysis unit 121 of the group division unit 102 converts (generates) the EPG title data extracted in the process of step S102 into text data.

In step S122 , the morpheme analysis unit 121 performs morpheme analysis on the text data generated in the process of step S121. Thereby, for example, the character string included in the EPG as the title of the content is divided into morphemes.

  In step S123, the keyword detection unit 122 of the group division unit 102 compares each morpheme obtained as a result of the process of step S122 or a word composed of continuous morphemes with preset dictionary data or the like. Is detected. As described above, the keyword is, for example, a word suitable for analyzing the title of the content, and is registered in advance as dictionary data. Among the words composed of each morpheme or continuous morpheme, the keyword is included in the dictionary data. What matches the registered word is detected as a keyword, and is output together with information representing the part of speech of the keyword.

  For example, suppose that the title of a certain content contains information consisting of the character string “MHK High School Course Science Comprehensive Science A / B“ The weather changes ””. By the processing in steps S122 and S123, for example, a list of keywords as shown in FIG. 5 is obtained.

  In FIG. 5, the keywords No. 1 to No. 14 are shown, and these keywords are derived from the character string (text data) of “MHK High School Course Science Comprehensive Science A and B“ The weather changes ””. This is obtained as a result of performing morphological analysis on the information and performing keyword detection.

  In this example, the No. 1 (first) keyword is “MHK High School Course”, and the part of speech is “noun”. The second keyword is “”, that is, a space (blank), and its part of speech is “blank”. Thus, a blank is also detected as a keyword. The third keyword is “Science”, a noun, the fourth keyword is “General”, a noun, and the fifth keyword is “A”, an alphabet.

  The sixth keyword is “·”, and the part of speech is “symbol”. In this way, the symbol is also detected as a keyword, and ““ ”as the eighth keyword and“ ”” (brackets) as the fourteenth keyword are also detected as the keyword of the symbol.

  The ninth to thirteenth keywords are respectively detected as part-of-speech keywords such as nouns, particles, and endings.

  Returning to FIG. 4, in step S124, the group dividing unit 102 groups the character string of the EPG title data based on the keyword list as shown in FIG. 5, for example, obtained through the process of step S123. Turn into.

  Here, for example, as shown in FIG. 6, character strings of EPG title data are grouped. In FIG. 6, each of the 14 keywords described above is surrounded by a rectangular frame, and the character string of EPG title data composed of the 14 keywords is divided into 3 groups.

  That is, the first group, Group 1, is composed of the first keyword “MHK High School Course”. Group 2, which is the second group, is composed of “Science Comprehensive A / B” which is the third to seventh keywords. The group 3 includes the ninth to thirteenth keywords “climate where weather changes”. In this way, a group composed of one or a plurality of keywords is generated, and EPG title data divided into groups is generated.

  The group division unit 102 groups character strings of EPG title data based on, for example, preset symbol keywords. In the example of FIG. 6, the character string of the EPG title data is divided into group 1 and group 2 by a blank symbol that is the second keyword. The character string of the EPG title data is divided into groups 2 and 3 by “8” and “14” (key brackets) as the eighth and fourteenth keywords. The sixth keyword “·” is a symbol that is a symbol but is not used for group division processing.

  In this way, the character strings of the EPG title data are grouped on the basis of preset symbol keywords. An example of symbols used for group division processing is shown in FIG.

  In the example of FIG. 7, symbols such as ““ ”,“ ””, “▽”, “/”, “:”, “# 1” are used as symbols used for group division processing in addition to spaces and square brackets. It is shown. Among these, “# 1” indicates, for example, a combination of a symbol “#” and a number as a keyword of one symbol.

  In this way, the group division process is executed.

  Returning to FIG. 3, after the process of step S <b> 103, in step S <b> 104, the aggregation unit 103 executes a folder creation process which will be described later with reference to FIG. 8. At this time, for example, the EPG title data of each of the plurality of recorded contents, and the common parts in the EPG title data of the plurality of contents grouped through the processing of step S103 are collected as a folder. It will be.

  Here, a detailed example of the folder creation processing in step S104 in FIG. 3 will be described with reference to the flowchart in FIG.

  In step S141, the aggregation unit 103 determines, for example, whether there is a common group in each grouped EPG title data of a plurality of recorded contents.

  When it is determined in step S141 that there is a common group, in step S142, the aggregation unit 103 sets the common group as a folder.

  As an example, a case will be described in which, for example, EPG title data of grouped six contents as shown in FIG. In this example, the first grouped EPG title data is “MHK High School Course Science Comprehensive Science A / B“ The weather changes ””, and the second grouped EPG title data is “MHK High School Course Science A / B“ Let's Use the Power of Electronics ”” and the third grouped EPG title data is “MHK High School Course Physics“ Work and Work Rate ”” The fourth grouped EPG title data is "MHK High School Course Physics" Brushing Waves "".

  In step S141, it is determined whether or not the first group (group 1) among the plurality of grouped EPG title data is common. In this case, the first to fourth grouped EPG title data group 1 (MHK high school course) in FIG. 9 is common. Accordingly, in step S142, the folder “MHK High School Course” is generated. Similarly, since the group 1 (MHK special) of the fifth and sixth grouped EPG title data is common, the folder “MHK special” is created.

  Returning to FIG. 8, after the process of step S142, in step S143, the aggregation unit 103 determines whether there is a more common group in the EPG title data grouped with each of a plurality of contents, for example. .

  When it is determined in step S143 that there is a common group, in step S144, the aggregation unit 103 sets the common group as a folder.

  In step S143, it is determined whether or not the second group (group 2) among the plurality of grouped EPG title data is further shared. In this case, the first and second grouped EPG title data groups 2 (science synthesis A and B) in FIG. 9 are common. Accordingly, in step S143, the folder “Science Comprehensive A / B” is generated as a lower folder of the folder “MHK High School Course”. Similarly, since the group 2 (physical) of the third and fourth grouped EPG title data is common, the folder “physical” is generated as a subordinate folder of the folder “MHK High School Course”. Since the fifth and sixth grouped EPG title data group 2 (planet booth) is common, the folder “planet booth” is created as a lower folder of the folder “MHK special”.

  That is, in FIG. 9, a portion surrounded by a dotted line or a portion surrounded by an alternate long and short dash line is a folder, and the hatched portion is the difference data of EPG title data.

  Note that since the fifth and sixth grouped EPG title data are common to both groups 1 and 2, one folder "MHK Special Planet Booth" may be created.

  If it is determined in step S141 in FIG. 8 that there is no common group, or if it is determined in step S143 that there is no common group, the folder creation process ends.

  The example described above with reference to FIGS. 8 and 9 is an example of creating a folder, and the folder may be generated by a different method. For example, as shown in FIGS. 8 and 9, the number of folders is not limited to being created up to two levels, but may be created as three levels, four levels,... For example, even if group 1 is common to each other, if the number of keywords included in group 1 is less than a predetermined number, a folder may not be created, or group 1 may not be common. When group 2 is common, group 2 may be generated as an upper folder.

  In this way, common portions in the EPG title data of a plurality of grouped contents are collected as a folder.

  As a result, the title aggregation process of FIG. 3 is also ended.

  As a result of the title aggregation processing, for example, title aggregation data as shown in FIG. 10 is generated.

  In the example of FIG. 10, a folder “root” is provided as the highest folder of the title aggregation data. Then, as a folder under the folder “root”, the folder “MHK High School Course”, the folder “MHK Special Planet Booth”, the folder “Tonight's Cooking”, the folder “Machi Tengoku”, and the folder “Ritsuko's Room” are created. ing. Furthermore, a folder “physical” and a folder “science synthesis A / B” are created as subordinate folders of the folder “MHK High School Course”.

  In the same figure, the character string in the hatched frame becomes the difference data of the EPG title data.

  That is, in the example of FIG. 10, there are six contents aggregated in the folder “MHK High School Course”, two of which are further aggregated in the folder “Physical”, and another two contents are the folders. It is further consolidated into “Science Comprehensive A / B”.

  Similarly, there are two contents aggregated in the folder “MHK Special Planet Booth”, two contents aggregated in the folder “Tonight's Cuisine”, and three contents aggregated in the folder “Town Heaven”. There are three contents aggregated in the folder “Ritsuko's Room”.

  Also, the content with EPG title data “Kihei” and the content with “Iwashi no Karakuri TV” were not shared with other content in the grouped EPG title data. It is not consolidated into folders.

  In the folder “Tonight's dish”, two contents are aggregated, but the hatched difference data is blank. This indicates that there are two contents whose EPG title data is only “tonight's dish”, and there is no difference data of the EPG title data in these two contents.

  Note that the title aggregation data as shown in FIG. 10 is stored in a predetermined area of the HDD 53 by the control unit 105. The hatched portion of the title aggregated data includes, for example, information indicating the recording position of the content data in the HDD 53 (address) as information specifying the content together with the difference data of the EPG title data. Etc.) are stored in association with each other.

  Next, content title setting processing will be described with reference to the flowchart of FIG. This processing is executed when content title data is set for each content in a state where a plurality of content is already recorded in the HDD 53, for example.

  In step S201, the content title setting unit 104 acquires title aggregation data. At this time, for example, title aggregation data as shown in FIG. 10 is acquired via the control unit 105.

  In step S202, the content title setting unit 104 checks the nth content. Note that the initial value of the variable n is 1. At this time, for example, as the nth one piece of content, a hatched square frame is checked one by one in FIG.

  In step S203, the content title setting unit 104 determines whether there is difference data in the nth content. If it is determined that there is difference data, the process proceeds to step S204.

  In step S204, the content title setting unit 104 sets the difference data determined to be present as the content title data of the content in the process of step S203.

  For example, when the title aggregation data of FIG. 10 is acquired in the process of step S201, when the first content is checked in the process of step S202, in the process of step S203, a difference is added to the first content. It is checked whether there is data. In this case, since the first content is a rectangular frame described as ““ work and work rate ”” in the figure, ““ work and work rate ”” is the difference data. Accordingly, in step S204, the content title data of the first content is set to ““ work and work rate ””.

  Similarly, for example, in the case of the fifth content, the content title data of the content is “information A“ security of the Internet society ””. For example, in the case of the 18th content (the rightmost rectangular frame in FIG. 10), the content title data of the content is “Iwashi Karaku TV”.

  On the other hand, if it is determined in step S203 that there is no difference data in the nth content, the process proceeds to step S205.

  In step S205, the content title setting unit 104 determines whether there is detailed information about the content. Here, the detailed information is information included in the EPG, and includes, for example, detailed information such as contents and performers.

  For example, the content title setting unit 104 outputs, to the EPG data acquisition unit 101 via the control unit 105, an information acquisition request for information specifying the content and detailed information included in the EPG data of the content. When the data acquisition unit 101 appropriately acquires the detailed information included in the EPG data of the content, the detailed information is supplied to the content title setting unit 104 via the control unit 105. In step S205, the details of the content It is determined that there is information.

  On the other hand, for example, when the EPG data acquisition unit 101 cannot appropriately acquire the detailed information included in the EPG data of the content, it is determined in step S205 that there is no detailed information of the content.

  If it is determined in step S205 that there is detailed information on the content, the process proceeds to step S206, and the content title setting unit 104 determines that the detailed information determined in step S205 is the content (n Set as the content title data of the (th content). For example, if the detailed information has a number of characters greater than or equal to a preset number, a predetermined number of characters are extracted from the detailed information and set as content title data. .

  If it is determined in step S205 that there is no detailed information about the content, the process proceeds to step S207, and the content title setting unit 104 sets EPG title data as content title data of the content (nth content). To do.

  For example, in FIG. 10, since there is no difference data in the two contents collected in the folder “Cooking tonight”, the process proceeds to step S205 by the determination in step S203.

  If there is detailed information in the two contents collected in the folder “Cooking tonight”, each detailed information is set as content title data. In this case, for example, the content of the content, which is included in the EPG data as detailed information, and the character string indicating the name of the dish or the character of the content, etc. It will be the title data.

  In addition, when there is no detailed information in the two contents collected in the folder “Tonight's dish”, the content title data of each content is both “Tonight's dish”.

  After the process of step S206 or step S207, the process proceeds to step S208, and the content title setting unit 104 determines whether there is a next content for which content title data has not yet been set, and the next content is determined. If it is determined that there is, the process proceeds to step S209, the value of the variable n is incremented by 1, and the process returns to step S202.

  Then, the processing from step S202 to step S209 is repeatedly executed until it is determined in step S208 that there is no next content.

  If it is determined in step S208 that there is no next content, the content title setting process ends.

  The content title setting process has been described as being executed when content title data is set for each content in a state where a plurality of contents are already recorded in the HDD 53. For example, the title aggregation in FIG. As the process is executed, content title data may be set for each content.

  In this case, for example, after the processing in step S144 in FIG. 8, the processing in steps S203 to S207 in FIG. 11 may be executed continuously.

In addition, for example, when the content title setting unit 104 sets content title data in the processing of step S204, step S206, or step S207, the broadcast date and time included in the EPG of the content via the EPG data acquisition unit 101 Information and broadcast time information may be acquired , and a character string representing the broadcast date and time, broadcast time, etc. of the content may be added to the content title data.

  In this way, a content title is set for each content.

  In this way, for example, when the user instructs the reproduction of content, display data for displaying a list of content titles for identifying the content to be reproduced on the screen more easily is generated. can do.

  For example, a case where a list of contents is displayed using a GUI (Graphical User Interface) as shown in FIG. 12 will be described as an example. In the example of FIG. 12, icons 211, 212, 213,... Are displayed on the display screen 201. The icon 211 is an icon representing video (movie) content, the icon 212 is an icon representing music (music) content, and the icon 213 is an icon representing photo (photo, still image) content. The For example, when the icon 211 is selected by a user operation, a list of moving image contents recorded in the HDD 53 of the data processing apparatus 11 is displayed.

  FIG. 13 shows a display example of a conventional content list. In the figure, for example, when the icon 211 is selected by a user operation, the GUI is displayed on the display screen 201, and the thumbnail of each content and the EPG title data of the content are displayed. For example, when the user selects a thumbnail displayed on the display screen 201, content data corresponding to the thumbnail is read from the HDD 53 and reproduced.

  In this example, thumbnails 231 to 237 are displayed in a line in the vertical direction in the figure on the left side of the display screen 201, and EPG title data is displayed on the right side of the thumbnails 231 to 237. A list of seven contents corresponding to the thumbnails 231 to 237 is displayed on the display screen 201. These contents include, for example, a plurality of games played in an international soccer tournament “2006 VIVA World Cup”. Each was broadcast and broadcast. For example, “2006 VIVA World Cup“ Uku ”is displayed on the right side of the thumbnail 231. Further, “6/29 (Thu) 3:45 AM” is displayed as the broadcast date and time of this content, and “(2H15M)” (representing 2 hours and 15 minutes) is displayed as the broadcast time of the content.

  The “2006 VIVA World Cup“ Uku ”displayed on the right side of the thumbnail 231 is that the actual EPG title data is“ 2006 VIVA World Cup “Ukraine” vs. “Switzerland” ”. The “liner” vs. “Switzerland” portion is deleted and displayed.

  Similarly, EPG title data displayed on the right side of the thumbnails 232 to 237 is also displayed with a part thereof deleted for convenience of the display area of the screen.

  Thus, since the conventional EPG title data is displayed as the title of the content, for example, the portion “2006 VIVA World Cup” represents a battle country that is important for the user although it is repeatedly displayed. Part of the character string (for example, “Ukraine” vs. “Switzerland”) is not displayed.

  On the other hand, according to the present invention, for example, a list of contents can be displayed as shown in FIGS. For example, the controller 52 of the data processing device 11 generates display data for a display screen as described below, and outputs the display data to the television receiver 12 so that the content on the screen of the television receiver 12 will be described later. A list of will be displayed.

  When the user desires to reproduce the content of a predetermined moving image recorded in the HDD 53, the video icon 211 is selected by the user's operation, for example, in the GUI of FIG. 14 is displayed. In the example of FIG. 14, folders 221 to 223 in which moving image contents are aggregated are displayed on the display screen 201 together with icons 211. The folders 221 to 223 are, for example, folders created by the process described above with reference to FIG. 8, and a plurality of contents are aggregated.

  On the right side of the folder 221 in the figure, “2006 VIVA World Cup” which is the name of this folder is displayed, and below that, “Title number (representing the number of aggregated contents): 7” is displayed. Has been. As described above, since a folder is a common part of a plurality of grouped EPG title data, in this case, seven contents whose EPG title data includes the character string “2006 VIVA World Cup” are included. , The folder 221 is collected.

  Similarly, the folder 222 has a folder name “town heaven” and four contents are aggregated, and the folder 223 has a folder name “world business” and five contents are aggregated. It will be.

  In the GUI of FIG. 14, for example, when the folder 221 is selected by a user operation, for example, the GUI as shown in FIG. 15 is displayed on the display screen 201. In the example of FIG. 15, the thumbnails 231 to 237 of the seven contents included in the folder 221 are displayed in the vertical direction in the figure along with the selected folder 221 corresponding to the icon 211 and the icon 211 on the display screen 201. Are displayed in a row. For example, when a user selects a thumbnail displayed on the display screen 201, content data corresponding to the thumbnail is read from the HDD 53 and played back.

  In this example, the name “2006 VIVA World Cup” that is the name of the folder 221 and the character string “title number: 7” that represents the number of contents aggregated in the folder 221 are displayed on the upper left side of the display screen 201. It is displayed.

  In addition, on the right side of the thumbnails 231 to 237 in the figure, the content title data of each content is displayed. For example, “Ukraine” vs. “Switzerland” is displayed on the right side of the thumbnail 231. Further, “6/29 (Thu) 3:45 AM” is displayed as the broadcast date and time of this content, and “(2H15M)” (representing 2 hours and 15 minutes) is displayed as the broadcast time of the content.

  “Ukraine” vs. “Switzerland” displayed on the right side of the thumbnail 231 is the content title data set by the processing described above with reference to FIG. 11 and the actual EPG title data “2006 VIVA World Cup”. The difference data of “Ukraine” vs. “Switzerland” is extracted and set as “Ukraine” vs. “Switzerland”.

  Similarly, the content title data displayed on the right side of the thumbnails 232 to 237 also corresponds to the difference data in the actual EPG title data.

  As described above, when there is no difference data in the EPG title data, the character string included in the detailed information of the EPG is the content title data. That is, the content title data displayed on the right side of the thumbnails 231 to 237 may be a character string included in the detailed information of the EPG.

  The character strings such as “6/29 (Thu) 3:45 AM” displayed as the broadcast date and time of the content and “(2H15M)” displayed as the broadcast time of the content are, for example, step S204 in FIG. When the content title setting unit 104 sets content title data in the process of step S206 or step S207, the broadcast date and time information and broadcast time information included in the EPG of the content are set via the EPG data acquisition unit 101. Can be easily displayed when a list of contents is displayed.

  Thus, according to the present invention, for example, the common part “2006 VIVA World Cup” in the EPG title data of a plurality of contents is displayed as the name of the folder 221, and is a character representing the opponent country that is important for the user. Since the part of the column (for example, “Ukraine” vs. “Switzerland”) is displayed as the title of each content, the desired content can be selected quickly.

  FIG. 16 is a diagram showing another display example of a list of contents according to the present invention.

  In this case, when the user desires to reproduce the content of a predetermined moving image recorded in the HDD 53, the video icon 211 is selected by the user's operation in the GUI of FIG. For example, it is assumed that a GUI displaying a plurality of folders in which moving image contents are aggregated is displayed together with the icon 211 described above with reference to FIG. 14, and one of the folders is selected. At this time, a GUI as shown in FIG. 16 is displayed. In this case, it is assumed that the folder 225 is selected. The folders 224 to 227 are, for example, folders created by the process described above with reference to FIG. 8, and a plurality of contents are collected.

On the right side of the folder 225 in the figure, the name of the folder “continuous television-style dolphin” is displayed, and below that, “number of titles: 3” is displayed. As described above, a folder is a common part of a plurality of grouped EPG title data. In this case, the EPG title data includes three strings that contain the character string “continuous TV-style dolphin”. The contents are collected in the folder 225 .

  When the folder 225 is selected, thumbnails 241 to 243 corresponding to the three contents collected in the folder 225 are displayed. For example, when a user selects a thumbnail displayed on the display screen 201, content data corresponding to the thumbnail is read from the HDD 53 and played back.

  Then, on the right side of the thumbnails 241 to 243 in the figure, the content title data of each content is displayed. For example, on the right side of the thumbnail 241, “(54)“ Kaze Day with Mom ”” is displayed. Furthermore, “12/12 (Tuesday)” is displayed as the broadcast date of this content below.

  “(54)“ Case Day is Mother ”” displayed on the right side of the thumbnail 241 is the content title data set by the processing described above with reference to FIG. 11 and the actual EPG title data “ Continuous TV-style dolphins (54) The difference data of “Kaze Day and Mom” are extracted and set as “(54)“ Kaze Day and Mom ””. is there.

  Similarly, the content title data displayed on the right side of the thumbnails 242 and 243 also corresponds to the difference data in the actual EPG title data.

  As described above, when there is no difference data in the EPG title data, the character string included in the detailed information of the EPG is the content title data. That is, the content title data displayed on the right side of the thumbnails 241 to 243 may be a character string included in the detailed information of the EPG.

  FIG. 17 is a diagram showing still another display example of a list of contents according to the present invention.

  In the case of FIG. 17, as in the case of FIG. 16, when the user desires to reproduce the content of the predetermined moving image recorded in the HDD 53, the video icon is displayed by the user's operation in the GUI of FIG. 211 is selected, and the display screen 201 displays, for example, the icon 211 described above with reference to FIG. 14 and a GUI displaying a plurality of folders in which moving image contents are aggregated. When one of the folders is selected, a GUI as shown in FIG. 17 is displayed.

  In the case of FIG. 17, it is assumed that the contents aggregated in the folder 225 and the folder 226 in FIG. 16 are aggregated in the folder 225, which is a higher folder. In other words, EPG title data contains “continuous TV-style dolphins” and EPG title data contains “continuous television wakagi”. Assume that a folder 225 that is “continuous television” is created by the process described above with reference to FIG.

  When the folder 225 is selected, the folder 228 and the folder 229 are displayed on the right side of the folder 225. The folder 228 is named “Wind Dolphin” and three contents are collected (number of titles: 3). The folder 229 is named “Wakagi”, and three contents are collected (number of titles: 3). Note that the folder 228 and the folder 229 are also folders created by the process described above with reference to FIG.

  Furthermore, when the folder 228 is selected, thumbnails 241 to 243 corresponding to each of the three contents collected in the folder 228 are displayed. For example, when a user selects a thumbnail displayed on the display screen 201, content data corresponding to the thumbnail is read from the HDD 53 and played back.

  In this case, for example, when the user moves the GUI cursor, only the content title data of the content corresponding to the focused thumbnail is displayed on the right side of the thumbnail. In this example, it is assumed that among the thumbnails 241 to 243, the thumbnail 242 is focused, and the content title data “(55)“ Dolphin Spring Break 1 ”” of the content is displayed on the right side of the thumbnail 242 in the drawing. ing. Further, “12/13 (Wednesday)” is displayed as the broadcast date of this content below.

  In this way, it is possible to make it easier to search for desired content by hierarchically displaying the folders in which the content is aggregated.

  By the way, as described above with reference to FIG. 1, the printer 13 is connected to the data processing device 11. For example, when content recorded on the HDD 53 is copied or moved to a DVD, the content title data of the content may be printed on the DVD by the printer 13.

  The printer 13 prints characters on the surface (a surface different from the recording surface) of a disk-shaped recording medium such as a DVD, for example, based on the printing data supplied from the data processing device 11, for example. Is supposed to be possible.

  Printing a content title or the like on a recording medium such as a DVD has been conventionally performed. FIG. 18 and FIG. 19 are diagrams showing examples of printing a conventional content title on a recording medium.

  The example of FIG. 18 shows a disc 301 on which 18 contents of a series program “Machi Tengoku” broadcast continuously are recorded. In the figure, the broadcast date of the content and the EPG title data of the content are displayed in a line in the vertical direction in the figure. On the right side of the disk 301 in the drawing, EPG title data “Machi Tengoku” of nine contents broadcast from April 22, 2006 to June 17, 2006 are printed together with the broadcast date. Also, on the left side of the figure of the disc 301, EPG title data “Machi Tengoku” of nine contents broadcast from June 24, 2006 to August 19, 2006 is printed together with the broadcast date.

  The example of FIG. 19 shows a disc 301 on which 18 contents of a series program “Ritsuko's Room” broadcast continuously are recorded. In the figure, the broadcast date of the content and the EPG title data of the content are also displayed in a line in the vertical direction in the figure. On the right side of the figure of the disc 301, EPG title data “Ritsuko's room” of nine contents broadcast from August 14, 2006 to August 24, 2006 is printed together with the broadcast date. Further, on the left side of the figure of the disc 301, EPG title data “Ritsuko's room” of nine contents broadcast from August 25, 2006 to September 6, 2006 are printed together with the broadcast date.

  However, if the user wants to reproduce the desired content recorded on the recording medium, whether the desired content is recorded on the disc 301 even when viewing the printed recording medium as shown in FIG. It is difficult to judge whether or not. For example, a series program that is broadcast continuously often has different coverage locations and performers depending on the broadcast date, and users want to play content such as coverage locations and performers that they are interested in. However, even if the title of the content is printed as shown in FIG. 18 or FIG. 19, it is not known whether the content such as the interview location or performer who is interested is recorded.

  In addition, the EPG title data may include a character string indicating the coverage area or performer of the content, but the character string of the EPG title data is within a limited printable area on the surface of the disc 301. It is difficult to print all the characters, and if it is intended to print all the character strings of the EPG title data, it is necessary to make the character size extremely small, which is also difficult for the user to understand.

  Therefore, in the present invention, the content title data described above is printed on a recording medium.

  20 and 21 are diagrams showing examples of printing of a content title on a recording medium according to the present invention. That is, FIGS. 20 and 21 show examples of the surface of the disk 301 on which characters and the like are printed by the printer 13 based on printing data generated and supplied by the controller 52 of the data processing apparatus 11, respectively.

  FIG. 20 shows a disc 301 on which 18 contents of a series program “Machi Tengoku” broadcast continuously are recorded as in the case of FIG. In FIG. 20, a part of the EPG title data of the content is printed in the area 321 on the surface of the disc 301. In this example, “town heaven” is printed. That is, in the area 321, the name of the folder created by the processing described above with reference to FIG. 8, for example, is printed in the EPG title data of the 18 contents.

  In the area 322, the earliest day (April 22, 2006) and the last day (August 19, 2006) of the broadcast date of the content recorded on the disc 301 are printed. On the lower side, it is printed that the number of titles representing the number of recorded contents is 18, and further, the total number of broadcast times of the contents recorded on the lower side is 18 hours. It is printed.

  In the areas 323 and 324, content title data corresponding to the contents of each broadcast day is printed. These content title data are content title data set by the processing described above with reference to FIG. 11, for example, a character string corresponding to each difference data of EPG title data of a plurality of contents, and Is done. In the example of the figure, the broadcast date of the content is printed on the left side of each content title data, and each content title data represents the coverage of the program “Town Heaven” on the broadcast date. .

  FIG. 21 shows a disc 301 on which 18 contents of a series program “Ritsuko's Room” broadcast continuously are recorded, as in FIG. In FIG. 21, a part of the EPG title data of the content is printed in the area 321 on the surface of the disc 301. In this example, “Ritsuko's room” is printed. That is, in the area 321, the name of the folder created by the processing described above with reference to FIG. 8, for example, is printed in the EPG title data of the 18 contents.

  It is assumed that the EPG title data of 18 contents recorded on the disc 301 in FIG. 21 are all “Ritsuko's room”, and there is no difference data.

  In the area 322, the earliest day (August 11, 2006) and the last day (September 6, 2006) of the broadcast date of the content recorded on the disc 301 are printed. On the lower side, it is printed that the number of titles representing the number of recorded contents is 18, and further, the total number of broadcast times of the contents recorded on the lower side is 18 hours. It is printed.

  In the areas 323 and 324, content title data corresponding to the contents of each broadcast day is printed. Each of these content title data is content title data set by the processing described above with reference to FIG. 11, and is, for example, a character string extracted from detailed information of each EPG of a plurality of contents. In the example in the figure, the broadcast date of the content is printed on the left side of each content title data, and each content title data indicates the main performer of the program “Ritsuko's Room” on that broadcast date. Represents.

  In addition, a plurality of contents of the series program “Machi Tengoku” broadcast continuously and a plurality of contents of the series program “Ritsuko's room” broadcast continuously are recorded on the same disc 301, respectively. FIG. 22 shows an example of printing of the titles on the recording medium. That is, FIG. 22 shows an example of the surface of the disk 301 on which characters and the like are printed by the printer 13 based on the printing data supplied from the data processing device 11.

  FIG. 22 shows a disc 301 on which 9 contents of a series program “Machi Tengoku” broadcast continuously and 9 contents of a series program “Ritsuko's Room” broadcast continuously are recorded. Yes. That is, a plurality of series programs are collectively recorded on one disc 301.

  In FIG. 22, a part of the EPG title data of the contents is printed in the area 341 and the area 351 on the surface of the disc 301, respectively. In this example, “city heaven” is displayed in the area 341 and “Ritsuko ’s in the area 351. "Room" is printed. That is, in the area 341, the names of folders created by the processing described above with reference to FIG. 8 are printed, which are common portions in the EPG title data of the nine contents. In the area 351, the name of the folder created by the process described above with reference to FIG. 8 is printed, which is a common part in the EPG title data of the other nine contents.

  In the area 342, the earliest day (June 24, 2006) and the last of the broadcast dates of the nine contents collected in the folder with the name corresponding to the area 341 are the contents recorded on the disc 301. Is printed (August 19th, 2006), and on the lower side, it is printed that the number of titles representing the number of recorded contents is 9, and is further recorded on the lower side. It is printed that the total number of broadcast hours of the content is 9 hours.

  In the area 343, the content title data of each of the nine contents collected in the folder having the name corresponding to the area 341 is printed. Each of these content title data is the content title data set by the processing described above with reference to FIG. 11, and in this example, the broadcast date of the content is printed on the left side of each content title data in the figure. Yes.

  In the area 352, the earliest date (August 11, 2006) and the last of the broadcast dates of the nine contents collected in the folder corresponding to the area 351 are the contents recorded on the disc 301. Is printed on the lower side (August 24, 2006), and it is printed on the lower side that the number of titles representing the number of recorded contents is 9, and is further recorded on the lower side. It is printed that the total number of broadcast hours of the content is 9 hours.

  In the area 353, the content title data of each of the nine contents collected in the folder having the name corresponding to the area 351 is printed. Each of these content title data is the content title data set by the processing described above with reference to FIG. 11, and in this example, the broadcast date of the content is printed on the left side of each content title data in the figure. Yes.

  As described above, according to the present invention, for example, the common part “town heaven” or “Ritsuko's room” in the EPG title data of a plurality of contents is displayed as the folder name, and is important for the user. The character string that represents (for example, coverage, performers, etc.) is displayed as the title of each content. It is possible to easily identify whether or not it is recorded on a recording medium.

  FIG. 23 is a diagram showing a print example of a content title on a recording medium according to the present invention when a plurality of contents aggregated in a plurality of folders are recorded on one recording medium. That is, FIG. 23 shows an example of the surface of the disk 301 on which characters are printed by the printer 13 based on the printing data supplied from the data processing device 11.

  In the present case, for example, “MHK High School Course” is created as the upper folder by the process described above with reference to FIG. 8, and the folder “English” and the folder “Chemistry” are created as lower folders of the folder “MHK High School Course”. ”, The folder“ Japanese history ”, and the folder“ geography ”are created, and three contents are aggregated in each of the four folders. It is assumed that 12 (= 4 × 3) contents are recorded on the disc 301.

  In FIG. 23, a part of the EPG title data of the content is printed in the area 321 on the surface of the disc 301. In this example, “MHK High School Course” is printed. That is, in the area 321, the name of the highest folder created by the processing described above with reference to FIG. 8, for example, is printed in the EPG title data of the 12 contents.

In the area 322 , the earliest date (August 11, 2006) and the last date (August 28 , 2006) of the broadcast date of the content recorded on the disc 301 are printed. On the lower side, it is printed that the number of titles indicating the number of recorded contents is 12, and further, the total number of broadcast times of the contents recorded on the lower side is 12 hours. It is printed.

  In the areas 361 to 364, the content title data corresponding to the contents of the individual broadcast days are printed. In the upper side of the area 361 to the area 364, the folder with the name printed in the area 321 is displayed. The names of the lower four folders are printed.

  That is, the area 361 is an area for printing the content title data of the three contents aggregated in the folder “English”, and the area 362 is the content title data of the three contents aggregated in the folder “Chemical”. The area 363 is an area for printing the content title data of the three contents aggregated in the folder “Japanese history”, and the area 364 is the content title data of the three contents aggregated in the folder “geography”. Is an area to be printed.

  Each of these content title data is content title data set by the processing described above with reference to FIG. 11, and is, for example, a character string corresponding to difference data of each EPG title data of a plurality of contents. The Further, in the example of the figure, the broadcast date of the content is printed on the left side of each content title data in the figure.

  In this way, by displaying the folders in which the contents are aggregated in a hierarchical manner, it is possible for the user to check whether or not the contents such as interview places and performers who are interested in the contents are recorded on the recording medium. Can be identified more easily.

  Here, an example in which content is recorded on the disc 301 has been described as an example of the recording medium. However, the recording medium on which the content is recorded is not limited to the disc-shaped recording medium, and such a recording medium may be used. Even if it exists, this invention is applicable.

  By the way, according to the present invention, title aggregation data as shown in FIG. 10 is generated, and as described above, if there is a common part in the grouped EPG title data, a folder is created and content is created. However, how many folders are generated depends on the EPG title data of the content.

  That is, as described above, when the second group is further common among the plurality of EPG title data grouped by the first group, a lower folder is created, and so on. The folder hierarchy will increase. In this way, for example, when the user instructs the reproduction of the content, it is easy to specify the content to be reproduced. However, if the folder hierarchy increases too much, it takes time to search for the desired content. There is a possibility that it will take.

  Therefore, in the present invention, when EPG title data of content is grouped and aggregated, for example, the user can designate how many folders are to be generated. That is, it is possible to set an upper limit on the number of layers of folders generated when EPG title data is grouped and aggregated, and no more folders can be generated.

  FIG. 24 is a diagram for explaining an example of a folder hierarchy in the present invention. This figure shows an example in which the upper limit of the number of hierarchy levels of folders generated when EPG title data is grouped and aggregated is set to 2.

  The first hierarchy in the figure is referred to as “view”, and is a hierarchy for designating, for example, a content list display method. The second hierarchy is referred to as a “group” and is a hierarchy that displays a group of contents that can be selected in accordance with the display method specified in the first hierarchy.

  The third and fourth hierarchies are called “group titles”, and as described above, are the hierarchies in which a list of contents aggregated by grouping EPG title data is displayed. In the third and fourth hierarchies, a folder is generated for content that has a common part by grouping EPG title data, and a content title is displayed as it is for content that has no common part. It will be.

  The fifth layer is called “title” and is a layer on which the title of the content is displayed. That is, when the EPG title data is grouped and aggregated, the upper limit of the number of layers of folders generated is set to 2, so there is a common part in the EPG title data of content in the fifth layer Even so, the folder is no longer generated and the title of the content is displayed as it is.

  FIG. 25 is a diagram illustrating a display example of the first layer screen. In the example shown in the figure, icons 401 to 405 are displayed as selectable icons in the first hierarchy.

  The icon 401 is a “reservation” icon, and when this icon is selected, the contents recorded by reservation recording are displayed in the second and lower layers. The icon 402 is a “genre” icon, and when this icon is selected, all contents recorded in the data processing device 11 are displayed in the second and lower layers. The icon 403 is an “automatic / full recording” icon, and when this icon is selected, automatically recorded content is displayed in the second and lower layers. Similarly, when the icon 404 and the icon 405 are selected, the contents are displayed according to predetermined criteria.

  The number of contents that can be displayed when each icon is selected is displayed as the “number of titles” on the right side of the icons 401 to 405 in the drawing.

  FIG. 26 is a diagram illustrating a display example of the second layer screen when the icon 402 in FIG. 25 is selected. In the example shown in the figure, when the “genre” icon 402 is selected, an icon 411 corresponding to the genre “news”, an icon 412 corresponding to the genre “sports”,..., An icon corresponding to the genre “movie”. 417 is displayed. When any of the icons 411 to 417 is selected, the contents belonging to the respective genres are displayed in the third and lower layers.

  The number of contents that can be displayed when each icon is selected is displayed as the “number of titles” on the right side of the icons 411 to 417 in the drawing. In addition, a symbol “NEW” displayed on the right side of the icons 411 to 417 in the drawing indicates that unreproduced content can be displayed when the icon is selected.

  FIG. 27 is a diagram showing a display example of the third layer screen when the icon 414 of FIG. 26 is selected. In the example shown in the figure, when the icon 414 of the genre “drama” is selected, contents belonging to the genre “drama” or folders in which the contents are aggregated are displayed.

For example, in the folder 421, contents including “SHOWBZ MAN” in the EPG title data are collected, and the display of “2006/4/14 2006/12/3” on the right side of the folder 421 in the figure is the folder 421. The content aggregated in 421 indicates that the content was recorded after April 14, 2006 AD and before December 3, 2006 AD. The number of contents aggregated in the folder 421 is the title. It is displayed as a number ( 2 in this case).

In the folder 422, contents including “only one love” in the EPG title data are aggregated. The number of contents (titles) that have been recorded before and collected in the folder 422 is 11. In the folder 423, contents including “continuous TV drama” in the EPG title data are aggregated, and the contents aggregated in the folder 423 are after March 17, 2006, before May 15, 2007. The number of content (number of titles) collected in the folder 423 is 21.

  In addition, since “NEW” is displayed on the right side of the folder 422 and the folder 423 in the drawing, it indicates that the contents aggregated in the folder 422 and the folder 423 include unreproduced contents, respectively. ing.

  The thumbnail 424 is a thumbnail corresponding to one content whose title specified by the EPG title data is “This is your way of life episode 2”. Similarly, the thumbnails 425 and 426 are thumbnails corresponding to one content, but “NEW” is displayed on the right side of the thumbnail 425 in the drawing, indicating that the content is not reproduced. Note that the thumbnail is not limited to the one representing the content, and may represent the playlist, for example.

  FIG. 28 is a diagram illustrating a display example of the fourth layer screen when the folder 423 in FIG. 27 is selected. In the example shown in the figure, when the folder 423 is selected, contents in which “continuous TV drama” is included in the EPG title data or folders in which the contents are aggregated are displayed.

  In the folder 431, contents including “encore” in the EPG title data are collected. That is, each of the contents collected in the folder 431 includes “continuous television drama” and “encore” in the EPG title data. The content aggregated in the folder 431 was recorded after April 14, 2006 AD and before October 15, 2006 AD. The number of contents aggregated in the folder 431 (number of titles) is 3 It is said that.

  Similarly, contents are also collected in the folder 432 and the folder 433, respectively. Since “NEW” is displayed on the right side of the folder 433 in the figure, it indicates that the contents collected in the folder 433 include unreproduced contents.

  The thumbnail 434 is a thumbnail corresponding to one content whose title specified by the EPG title data is “Continuous TV Drama My Autumn Color”. In other words, the portion corresponding to the difference among the titles of the contents aggregated in the third layer folder is displayed on the fourth layer screen. Similarly, the thumbnail 435 and the thumbnail 436 are thumbnails corresponding to one content. Since “NEW” is displayed on the right side of the thumbnail 435 in the figure, this content has not been reproduced.

  FIG. 29 is a diagram showing a display example of the fifth layer screen when the folder 433 of FIG. 28 is selected. In the example shown in the figure, by selecting the folder 433, the EPG title data includes “continuous television drama” and the titles of the contents including “uncle” are displayed.

  The thumbnail 441 is a thumbnail corresponding to one content whose title specified by the EPG title data is “Continuous TV Drama Ojin # 01”. In other words, since the folder is no longer displayed on the screen of the fifth layer, the portion corresponding to the difference among the titles of the contents aggregated in the folder of the fourth layer is the folder selected in the fourth layer (current In this case, the folder name of the folder 433) is displayed including the name of the folder (in this case, “Ojin”).

  Each of the thumbnails 442 to 446 is also a thumbnail corresponding to one content. Since “NEW” is displayed on the right side of the thumbnails 443 to 446 in the drawing, these contents are not reproduced.

  In this way, contents are aggregated into folders and displayed hierarchically.

  The display example described above with reference to FIGS. 25 to 29 is an example in which the icon 402 (“genre”) is selected in the first hierarchy (view). For example, in the first hierarchy, the icon When 405 (“x-Pict Story”) is selected, the contents are not aggregated into a folder, and all the individual contents are displayed together with thumbnails and the like on one level screen. That is, contents are aggregated into folders according to the type of view selected by the user and displayed in a hierarchical manner.

Figure 30 is a flowchart for explaining the folder additional information generating process of generating a folder additional information referring to the displayed on the right side in the figure in the folder displayed on the screen as described above Figure 27. This process is executed, for example, after a folder is created by the folder creation process described above with reference to FIG.

  In step S301, the aggregating unit 103 acquires one of the contents aggregated in one folder.

  In step S302, the aggregation unit 103 checks the recording start time of the content acquired in the process of step S301.

  In step S303, the aggregation unit 103 determines whether the recording start time acquired in the process of step S302 is before the time Ts. Here, Ts is a variable, and, for example, the current time is set as an initial value. If it is determined in step S303 that the recording start time is before time Ts, the process proceeds to step S304. If it is determined that the recording start time is not before time Ts, the process of step S304 is skipped. The

  In step S304, the aggregation unit 103 sets the recording start time acquired in the process of step S302 at time Ts.

  In step S305, the aggregation unit 103 determines whether or not the recording start time acquired in step S302 is after the time Te. Here, Te is a variable, and, for example, a time when the device is manufactured is set as an initial value. If it is determined in step S305 that the recording start time is later than time Te, the process proceeds to step S306. If it is determined that the recording start time is not later than time Te, the process of step S306 is skipped. The

  In step S306, the aggregation unit 103 sets the recording start time acquired in the process of step S302 at time Te.

  In step S307, the aggregation unit 103 determines whether or not the content has not been reproduced. If it is determined in step S307 that the content is not yet played back, the process proceeds to step S308. If it is determined that the content is not played back, the process in step S308 is skipped.

  In step S308, the aggregation unit 103 sets an unreproduced flag to ON.

  In step S309, the aggregating unit 103 increments the variable n indicating the number of contents aggregated in this folder by 1. Note that the initial value of the variable n is 0.

  In step S310, the aggregating unit 103 determines whether there is the next content aggregated in this folder. If it is determined that there is the next content, the process returns to step S301, and thereafter The process is repeatedly executed. If it is determined in step S310 that there is no next content collected in this folder, the process proceeds to step S311.

  In step S311, the aggregation unit 103 sets the start time of this folder as Ts, the end time as Te, and the number of contents as n. Thereby, for example, information corresponding to “2006/4/14 2006/12/3” and “title number: 3” on the right side of the folder 421 in FIG. 27 is displayed.

  In step S312, the aggregation unit 103 determines whether or not the unreproduced flag is ON. If it is determined that the unregenerated flag is ON, the process proceeds to step S313, and the unregenerated flag is ON. If it is determined that there is not, the process of step S313 is skipped.

  In step S313, the aggregation unit 103 sets a predetermined flag or the like for displaying “NEW” in the folder. Thus, for example, “NEW” is displayed on the right side of the folder as in the folder 422 and the folder 423 in FIG.

  Note that the processing from step S301 to step S313 is executed for all folders created by grouping and aggregating EPG title data.

  In this way, folder additional information is generated.

  By the way, in the present invention, as described above, folders in which contents are aggregated are displayed in a hierarchical manner. For example, a user selects a folder (or icon) in a predetermined hierarchy and the folder is selected. New contents may be added or contents may be deleted while displaying a list of contents or a list of lower folders.

  Here, in the present invention, when the user selects a folder (or icon) of a predetermined hierarchy and displays a list of contents aggregated in the folder or lower folders, new contents are added. A change in the display of the content or folder list when the content is deleted or deleted will be described.

  For example, as shown in FIG. 27, when the second level icon 414 is selected and a list of contents or folders corresponding to the icon 414 is displayed, “only one love” is displayed in the EPG title data. When the included content is newly recorded, the display screen shown in FIG. 27 is changed as shown in FIG.

  In the example of FIG. 31, the “number of titles” (number of contents) of the folder 422 in the third hierarchy whose folder name is “only one love” is changed to “12”. That is, when an icon of the second hierarchy is selected and a content corresponding to the icon or a list of folders of the third hierarchy is displayed, contents to be aggregated in the folder of the third hierarchy are added. In this case, the folder additional information displayed on the right side of the third layer folder is changed.

  In the example of FIG. 31, only the display of the “number of titles” of the folder 422 is changed, but the display of the start time or end time of the folder 422 is changed according to the content to which the display is added as necessary. Is done.

  Here, it has been described that when the content to be aggregated in the folder 422 in the third hierarchy is added, the “number of titles” in the folder 422 in the third hierarchy is changed (added). However, the contents are aggregated in the folder in the third hierarchy. Even if the content to be aggregated is added to the fourth-level folder, the “number of titles” of the third-level folder is also added.

  For example, in the state shown in FIG. 27, when a content whose title specified by the EPG title data is “continuous television drama Ojin # 07” is newly recorded, the name is “continuous television drama”. Since the content that is aggregated in the folder 433 that is a folder in the fourth hierarchy that is aggregated in the folder 423 in the third hierarchy and that has the name “Ojin” is increased, the folder 423 in the third hierarchy is added. The “number of titles” is changed to “22”.

  Further, in the state shown in FIG. 31, when one of the contents including “SHOWBZ MAN” in the EPG title data is deleted, the display screen shown in FIG. 31 is changed as shown in FIG. The

  In the example of FIG. 32, the “number of titles” (number of contents) of the folder 421 in the third hierarchy whose folder name is “SHOWBZ MAN” is changed to “1”. That is, when the second hierarchy icon is selected and the contents corresponding to the icon or the third hierarchy folder list is displayed, the contents aggregated in the third hierarchy folder are deleted. The folder additional information displayed on the right side of the third hierarchy folder is changed.

  In the example of FIG. 32, only the display of the “number of titles” of the folder 421 is changed, but the display of the start time or end time of the folder 421 is changed according to the deleted content as necessary. Is done.

  Here, it has been described that when the contents aggregated in the third level folder 421 are deleted, the “number of titles” of the third level folder 421 is changed (subtracted). However, the contents are aggregated in the third level folder. Even when the contents to be collected in the fourth layer folder are deleted, the “title number” of the third layer folder is also subtracted.

  For example, in the state shown in FIG. 27, when a content whose title specified by the EPG title data is “Continuous TV Drama Ojin # 01” is deleted, the name of the third hierarchy whose name is “Continuous TV Drama” is displayed. Since the content that is aggregated in the folder 433 that is a folder in the fourth hierarchy that is aggregated in the folder 423 and that is named “Ojin” is reduced by one, the “number of titles” in the folder 423 in the third hierarchy is reduced. "Is changed to" 20 ".

  When the content including “SHOWBZ MAN” in the EPG title data is further deleted in the state shown in FIG. 32, the display screen shown in FIG. 32 is changed as shown in FIG.

  In the example of FIG. 33, the folder 421 in the third hierarchy whose folder name is “SHOWBZ MAN” is deleted and is not displayed. That is, when the second level icon is selected and the content corresponding to the icon or the list of the third level folder is displayed, all the contents aggregated in the third level folder are deleted. In this case, the third-level folder itself is deleted.

  For example, if there is only one content aggregated in a folder, it may not be necessary to display the folder anymore, so delete the folder and change the screen display so that the content is displayed with thumbnails You can also. However, when a user selects a folder (or icon) at a predetermined level and displays a list of contents or a subordinate folder aggregated in the folder, the user is deleted when the subordinate folder is deleted. May cause an illusion that all the content corresponding to the name of the folder has been deleted. Further, when a folder is deleted, it becomes difficult to know where on the screen the contents collected in the folder are displayed.

  Therefore, in the present invention, as described above with reference to FIGS. 32 and 33, the user selects a folder (or icon) in a predetermined hierarchy, and the contents aggregated in the folder or lower folders are selected. When the list is displayed, even if there is only one content, for example, the content aggregated in the lower folder is deleted, the lower folder continues to be displayed and the content aggregated in the lower folder When all of are deleted, the folder is deleted.

  In this way, a list of contents can be displayed in a manner that is easy for the user to understand.

  Next, the content addition process will be described with reference to the flowchart of FIG. In this process, for example, when a user selects a folder (or icon) in a predetermined hierarchy and displays a list of contents aggregated in the folder or lower folders, new contents are added. It is executed when

  In step S341, the EPG data acquisition unit 101 extracts EPG title data of the added content, and supplies the EPG title data to the group division unit 102 via the control unit 105.

  In step S342, the group division unit 102 executes group division processing based on the EPG title data extracted in step S341. Since this process is the same as the process described above with reference to FIG. 4, the detailed description is omitted, but the character strings of the EPG title data are grouped based on the preset keyword of the symbol.

  In step S343, the aggregation unit 103 determines whether there is a matching folder for the character strings of the EPG title data grouped by the processing in step S342. This determination is made as to whether or not the lower-order folders collected in the folder (or icon) selected by the user match the character string of the EPG title data. For example, when the user selects the second level icon 414 and displays a list of contents corresponding to the icon 414 or third level folders (folders 421 to 423), the third level folder 421 is displayed. It is determined whether or not there is a folder in the folder 423 that matches the character string of the EPG title data.

  If it is determined in step S343 that there is a matching folder, the process proceeds to step S344.

  In step S344, the aggregating unit 103 determines whether or not the folder determined in the process of step S343 is a folder in a lower hierarchy, thereby determining whether there is a next hierarchy. judge. If it is determined in step S344 that there is a next hierarchy, the process proceeds to step S345, moves to the next hierarchy (lower hierarchy), and the process returns to step S343.

  If it is determined in step S343 that there is no matching folder, the process proceeds to step S346, and it is determined whether information specifying the folder determined to match in the process of step S343 has been acquired.

  If it is determined in step S346 that the information specifying the folder determined to match can be acquired, the process proceeds to step S347. In step S347, the aggregation unit 103 adds content to a folder that matches the character string of the EPG title data. That is, the contents collected in the folder are added.

  In step S348, the aggregation unit 103 adds 1 to the number of contents of the folder. Thereby, the “number of titles” of the folder additional information of the folder is changed. Further, the start time or end time of the folder additional information of the folder is changed as necessary.

  If it is determined in step S346 that information specifying a folder determined to match cannot be acquired, the processes in steps S347 and S348 are skipped.

  After the process of step S348, if it is determined in step S346 that the information specifying the folder determined to match cannot be acquired, or if it is determined in step S344 that there is no next hierarchy, the process is as follows. Proceeding to step S349, the aggregating unit 103 determines whether there is other added content, and when it is determined that there is other added content, the process returns to step S341, and thereafter The process is executed repeatedly.

  If it is determined in step S346 that the information specifying the folder determined to match cannot be acquired, there is no folder that matches the character string of the EPG title data. Therefore, the added content is It will be displayed without being consolidated into a folder.

  If it is determined in step S349 that there is no other content added, the process proceeds to step S350, and the display on the screen is changed. Thereby, for example, the display screen shown in FIG. 27 is changed as shown in FIG. 31 as described above.

  In this way, content addition processing is performed.

  Next, content deletion processing will be described with reference to the flowchart of FIG. This process is performed when, for example, a user selects a folder (or icon) at a predetermined level and displays a list of contents aggregated in the folder or lower folders, and the contents are deleted. Executed.

  In step S371, the aggregation unit 103 identifies the content to be deleted.

  In step S372, the aggregating unit 103 determines whether there is a folder in which the content specified in the process of step S371 is aggregated. Note that this determination is made as to whether or not the lower-level folders aggregated in the folder (or icon) selected by the user aggregate the contents to be deleted identified in the process of step S371. For example, when the user selects the second level icon 414 and displays a list of contents corresponding to the icon 414 or the third level folders (folders 421 to 423), the content to be deleted is the first level. It is determined whether or not all of the folders 421 to 423 in the three layers are collected.

  If it is determined in step S372 that there is a folder in which contents are aggregated, the process proceeds to step S373.

  In step S373, the aggregation unit 103 deletes the content (the content specified in the process of step S371) from the folder.

  In step S374, the aggregation unit 103 subtracts 1 from the number of contents in the folder. Thereby, the “number of titles” of the folder additional information of the folder is changed. Further, the start time or end time of the folder additional information of the folder is changed as necessary.

  In step S375, the aggregation unit 103 determines whether the number of contents in the folder is 1 or more. That is, for example, as a result of the content being deleted by the process of step S373, it is determined whether or not there is one or more contents (not 0) that are aggregated in the folder.

  If it is determined in step S375 that the number of contents is not 1 or more (the number of contents is 0), the process proceeds to step S376, and the aggregation unit 103 deletes the folder.

  On the other hand, if it is determined in step S375 that the number of contents is 1 or more, the process in step S376 is skipped.

  Note that if it is determined in step S372 that there is no folder in which contents are aggregated, the processing in steps S373 to S376 is skipped. If it is determined in step S372 that there is no folder in which the contents are aggregated, the contents are displayed together with thumbnails and the like without being aggregated in the folder. The contents are deleted together with the thumbnails and are not displayed.

  In step S377, the aggregation unit 103 determines whether there is other deleted content. If it is determined that there is other deleted content, the process returns to step S371, and the subsequent processing Is repeatedly executed.

In step S 377, if it is determined that has been no content deletion otherwise, the process proceeds to step S378, the display screen is changed. Thereby, for example, the display screen shown in FIG. 31 is changed as shown in FIG. 32 or 33 as described above.

  In this way, content deletion processing is performed.

  By the way, even for contents such as dramas that are broadcast continuously, different titles may be assigned only to the final or special broadcast times. In this way, content with a title different from the usual broadcast times may be collected in an appropriate folder even if the processing described above with reference to FIGS. 3, 4, and 8 is executed. It is also low, and it may be accidentally aggregated into another folder. For this reason, in the data processing device 11 of the present invention, the user can change the title of the recorded content.

  Here, in the present invention, when a user selects a folder (or icon) at a predetermined level and displays a list of contents aggregated in the folder or lower folders, the title of the content is changed. A description will be given of how to change the display of the list of contents or folders in the case of being performed.

  For example, as shown in FIG. 27, when the second level icon 414 is selected and a list corresponding to the icon 414 or a list of folders is displayed, two contents aggregated in the folder 421 are displayed. When the title of one of the contents is changed to “only one love”, the display screen shown in FIG. 27 is changed as shown in FIG.

  In the example of FIG. 36, the “title number” (the number of contents) of the third-level folder 421 whose folder name is “SHOWBZ MAN” is changed to “1 (= 2-1)”, and the folder name is changed. The “number of titles” (the number of contents) of the folder 422 in the third hierarchy which is “only one love” is changed to “12 (= 11 + 1)”. That is, when a second level icon is selected and a list of contents corresponding to the icon or a third level folder is displayed, the titles of the contents to be aggregated in the third level folder are changed. If it has been done, the folder additional information displayed on the right side of the third layer folder is changed.

  In the example of FIG. 36, only the display of the “number of titles” of the folder 421 and the folder 422 is changed, but the display of the start time or the end time of the folder 421 and the folder 422 is added as necessary. Changed according to the content.

  Next, content title change processing will be described with reference to the flowchart of FIG. In this process, for example, when a user selects a folder (or icon) at a predetermined level and displays a list of contents aggregated in the folder or lower folders, the title of the contents is changed. It is executed when

  In step S401, the aggregation unit 103 identifies content whose title is to be changed.

  In step S402, the aggregation unit 103 determines whether there is a folder in which the content specified in the process of step S401 is aggregated. This determination is made as to whether or not the lower-order folders aggregated in the folder (or icon) selected by the user aggregate the contents whose titles specified in the process of step S401 are to be changed. For example, when the user selects the second level icon 414 and displays a list of contents corresponding to the icon 414 or third level folders (folders 421 to 423), the content whose title should be changed. Is aggregated in any one of the folders 421 to 423 in the third hierarchy.

  If it is determined in step S402 that there is a folder in which contents are aggregated, the process proceeds to step S403.

  In step S403, the aggregating unit 103 deletes the content (content specified in the process of step S401) from the folder.

  In step S404, the aggregation unit 103 subtracts 1 from the number of contents in the folder. Thereby, the “number of titles” of the folder additional information of the folder is changed. Further, the start time or end time of the folder additional information of the folder is changed as necessary.

  In step S405, the aggregation unit 103 determines whether the number of contents in the folder is 1 or more. That is, for example, as a result of the content being deleted by the process in step S403, it is determined whether or not there is one or more contents (not 0) that are aggregated in the folder.

  If it is determined in step S405 that the number of contents is not 1 or more (the number of contents is 0), the process proceeds to step S406, and the aggregation unit 103 deletes the folder.

  On the other hand, when it is determined in step S405 that the number of contents is 1 or more, the process of step S406 is skipped.

  Note that if it is determined in step S402 that there is no folder in which contents are aggregated, the processing in steps S403 to S406 is skipped.

  In step S407, the EPG data acquisition unit 101 extracts EPG title data of the changed content, and supplies the EPG title data to the group dividing unit 102 via the control unit 105.

  In step S408, the group division unit 102 executes group division processing based on the EPG title data extracted in step S407. Since this process is the same as the process described above with reference to FIG. 4, the detailed description is omitted, but the character strings of the EPG title data are grouped based on the preset keyword of the symbol.

  In step S409, the aggregation unit 103 determines whether there is a matching folder for the character strings of the EPG title data grouped by the processing in step S408. This determination is made as to whether or not the lower-order folders collected in the folder (or icon) selected by the user match the character string of the EPG title data. For example, when the user selects the second level icon 414 and displays a list of contents corresponding to the icon 414 or third level folders (folders 421 to 423), the third level folder 421 is displayed. It is determined whether or not there is a folder in the folder 423 that matches the character string of the EPG title data.

  If it is determined in step S409 that there is a matching folder, the process proceeds to step S410.

  In step S410, the aggregating unit 103 determines whether the folder determined in step S409 is a folder of a lower hierarchy by determining whether there is a next hierarchy. judge. If it is determined in step S410 that there is a next hierarchy, the process proceeds to step S411, moves to the next hierarchy (lower hierarchy), and the process returns to step S409.

  If it is determined in step S409 that there is no matching folder, the process proceeds to step S412, and it is determined whether or not information specifying the folder determined to match in the process of step S409 has been acquired.

  If it is determined in step S412 that the information specifying the folder determined to match can be acquired, the process proceeds to step S413. In step S413, the aggregation unit 103 adds content to a folder that matches the character string of the EPG title data. That is, the contents collected in the folder are added.

  In step S414, the aggregation unit 103 adds 1 to the number of contents of the folder. Thereby, the “number of titles” of the folder additional information of the folder is changed. Further, the start time or end time of the folder additional information of the folder is changed as necessary.

  If it is determined in step S412 that the information specifying the folder determined to match cannot be acquired, the processes in steps S413 and S414 are skipped.

  After the process of step S414, if it is determined in step S412 that the information specifying the folder determined to match cannot be acquired, or if it is determined in step S410 that there is no next hierarchy, the process is as follows. Proceed to step S415.

  If it is determined in step S412 that the information specifying the folder determined to match cannot be acquired, the folder that matches the character string of the EPG title data does not exist, so the added content is It will be displayed without being consolidated into a folder.

  If it is determined in step S402 that there is no folder in which contents are aggregated, the contents are displayed together with thumbnails and the like without being aggregated in the folder, so the display regarding the folder is not changed. In addition, the content is deleted together with the thumbnail or the title of the content is changed and displayed.

  In step S415, the display on the screen is changed. Thereby, for example, the display screen shown in FIG. 27 is changed as shown in FIG. 36 as described above.

  In this way, the content title change process is performed.

  By doing in this way, it is possible to display a list of contents easily understandable for the user.
