Description

  The present invention relates to an information processing apparatus and method, a program recording medium, and a program, and more particularly to an information processing apparatus and method, a program recording medium, and a program that can improve the operability of character input.

  Conventionally, a portable terminal represented by a mobile phone or PDA (Personal Digital Assistant) or a signal receiving device with a built-in tuner or the like often has no keyboard for character input. When inputting, it is inconvenient to input characters by using a software keyboard that takes a long time to input or by connecting an external input device such as a keyboard.

  Corresponding to this, for example, by using a predictive conversion function such as POBox (registered trademark), for example, as shown in Japanese Patent Application Laid-Open No. 2003-260, or a portable terminal that allows a character to be input as quickly as possible. The character information image extracted from the moving image data is converted to text data without inputting characters, and the recorded video is based on the converted text data and the frame position information from which the character information image is extracted. Many proposals have been made to reduce the inconvenience of operability for character input, such as a content recording / reproducing apparatus that generates a table of contents screen of image data.

JP 2003-274352 A

  However, the above-described conventional proposals are often not effective when naming or changing the name of a folder or recording medium in which content is stored in a portable terminal or a signal receiving device.

  That is, the former candidate character string by the predictive conversion function is obtained by learning a character string input in the past (estimated character string from a past input pattern). Therefore, using such a predictive conversion function, if a new content is saved in a folder and an attempt is made to name the folder, only candidate character strings that are not related to the saved content and depend on past patterns are used. In the end, there was a risk of having to rely on software keyboard input.

  In the latter proposal, the character information image from the moving image data is converted into text data. Therefore, for example, in the case of content such as variety, various words are often displayed as telops, and even if you try to name a folder where the content is stored, text that is not related to the stored content If only the data is output, or conversely, in the case of the content with few telops, the desired text data is not output, and eventually there is a risk that the input using a software keyboard or the like must be relied upon.

  As described above, when naming or changing the name of a folder or recording medium in which content is stored, even if the conventional proposal as described above is used, the effect is rarely exhibited. Eventually, there is a problem that the operation is inconvenient because characters must be input by using a software keyboard that takes time to input or by connecting an external input device such as a keyboard.

  Further, in the signal receiving device, the title name of the content to be stored is often set by the signal receiving device based on EPG (Electronic Program Guide) information acquired in advance. Even in the case of changing, there is a problem that the operation of character input is inconvenient as in the case of naming or changing a folder or a recording medium.

  The present invention has been made in view of such a situation, and makes it possible to easily reduce the inconvenience of a character input operation.

Since the program recording medium and the program of the present invention have basically the same configuration as the information processing method of the present invention described above, the description thereof is omitted because it is repeated.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a configuration example of a signal receiving apparatus 1 to which the present invention is applied. The signal receiving device 1 receives and selects a terrestrial digital broadcast signal via an antenna 21 and outputs the video and audio to a display 28 and a speaker 29, or is equipped with a built-in storage unit 32. It is recorded as content on the recording medium 34. In the signal receiving device 1, an editing GUI (Graphical User Interface) screen is displayed on the display 28, and the user operates a wired or wireless remote controller (hereinafter referred to as a remote controller) (not shown), The media name, folder name of the storage unit 32 and the recording medium 34, or the title name of the recorded content can be edited. Hereinafter, a case where content is recorded on the recording medium 34 will be described as an example.

  In the example of FIG. 1, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a light receiving unit 14, and a nonvolatile memory 15 are connected to a CPU (Central Processing Unit) 11. The CPU 11 controls each unit of the signal receiving device 1 according to a program stored in the ROM 12, a program loaded in the RAM 13, or a user instruction signal obtained via the light receiving unit 14, and executes various processes. To do. The RAM 13 also appropriately stores data necessary for the CPU 11 to execute various processes. The light receiving unit 14 receives (receives) a user instruction signal (infrared signal) from the remote controller, and outputs the received user instruction signal to the CPU 11. The nonvolatile memory 15 stores EPG (Electronic Program Guide) information and various databases such as a candidate character string database 53 described later with reference to FIG. The EPG information and various databases may be configured to be stored in the storage unit 32.

  The CPU 11 performs a signal reception process of a broadcast signal via the bus 16, and includes a front end unit 22, a descrambler 23, a demultiplexer 24, a decoder unit 25, a recording processing unit 26, a reproduction processing unit 27, and a network. An interface (I / F) 31, a storage unit 32, and a drive 33 are connected, and execute predetermined processing according to the control of the CPU 11.

  The front end unit 22 extracts a broadcast signal corresponding to the user's channel selection from the broadcast signal received via the antenna 21, demodulates it, generates a transport stream, and outputs it to the descrambler 23. The descrambler 23 appropriately de-scrambles the transport stream input from the front end unit 22 and outputs the descrambler 24 to the demultiplexer 24. The demultiplexer 24 separates the multiplexed transport stream into, for example, MPEG (Moving Picture Experts Group) 2 or MPEG4 video and audio data streams, and section data.

  The demultiplexer 24 outputs video data and audio data to the decoder unit 25 or the recording processing unit 26, and outputs only necessary section data to the CPU 11. The decoder unit 25 decodes the video data and audio data from the demultiplexer 24, and outputs the decoded data to the reproduction processing unit 27. The recording processing unit 26 performs predetermined processing on the video data and audio data from the demultiplexer 24 and records them as content on the recording medium 34.

  In addition to the recorded content, the title name information and title name detailed information of the content are recorded on the recording medium 34, and a title list used as an index for searching the content recorded from the recording medium 34 is also recorded. Has been. Therefore, the recording processing unit 26 records the title name information and the title name detailed information along with the content, and further updates the title list recorded on the recording medium 34. Note that the title list may not be recorded on the recording medium 34. In this case, when the recording medium 34 is loaded in the drive 33, the title name information and the title name detailed information recorded together with the content are acquired and created.

  The CPU 11 expands each piece of information of the section data from the demultiplexer 24 in the RAM 13. The section data includes EPG information, data broadcast content data, information related to the data broadcast content, and the like. The EPG information is usually transmitted separately from video data and audio data, and is stored in the nonvolatile memory 15 or the like by the CPU 11. The CPU 11 expands the data broadcast content information of the section data into the RAM 13 and converts it into a predetermined format, or reads the editing GUI screen data for editing the title name of the content and the media name of the recording medium 34 from the ROM 12 or the like. And output to the reproduction processing unit 27.

  When recording video data and audio data as content on the recording medium 34, the CPU 11 supplies title information and title detailed information corresponding to the content to be recorded among the EPG information to the recording processing unit 26. The title name information is information on the title name set in advance for the recorded content. The detailed title information is detailed information on the content including the broadcast time, outline, performers, and the like regarding the content. Further, the CPU 11 updates the title list recorded on the recording medium 34 based on the title name information and the title detailed information, and causes the recording processing unit 26 to record the title list.

  That is, the user can search for content from the recording medium 34 by searching for a title name corresponding to the content from the title list. Note that the title name of the content can be edited (changed) in accordance with the user's operation, like the name of the folder in which the content is recorded and the media name of the recording medium 34.

  The CPU 11 extracts a character string from at least one piece of information of the title name information and title detailed information (hereinafter referred to collectively as title information when the title name information and the title detailed information are not required to be individually distinguished). Then, the extracted character string and the character string related to the extracted character string are registered in the candidate character string database 53 as candidate character strings. In the present invention, a character string refers to a character string consisting of at least one character.

  The candidate character strings registered in the candidate character string database 53 are edited, for example, by the user operating the remote controller, such as the title name of the content, the name of the folder in which the content is recorded, and the media name of the recording medium 34. Used in cases. That is, the candidate character string is a candidate character string used when editing the title name of the content, the folder name, or the media name of the recording medium 34. For example, the CPU 11 acquires a candidate character string from the candidate character string database 53 based on the title information of the content associated with the folder name to be edited (that is, the content managed in this folder). The edited GUI screen data reflecting the candidate character string is displayed on the display 28 via the reproduction processing unit 27. Thereby, the candidate character string corresponding to the folder name to be edited is displayed on the editing GUI screen of the display 28.

  The reproduction processing unit 27 adds (superimposes) the editing GUI screen data from the CPU 11 to the video data from the demultiplexer 24, converts it to a signal such as NTSC format, and converts the corresponding video to an LCD (Liquid Crystal Display). ) Or PDP (Plasma Display Panel) or the like, and the audio data from the demultiplexer 24 is output from the speaker 29.

  The network interface 31 is configured by a modem, an IEEE802.3 interface, etc., and establishes a data link with a server connected to a network (not shown). If necessary, FTP (File Transfer Protocol) or HTTP (Hyper Text Transport) Predetermined data is communicated by a data transfer protocol such as Protocol. The storage unit 32 records video data and audio data supplied from the recording processing unit 26 as content, and also records title information corresponding to the content. At this time, the title list recorded in the storage unit 32 is also updated.

  A recording medium 34 composed of a magnetic disk, an optical disk, a magneto-optical disk, a semiconductor memory, or the like is appropriately attached to the drive 33. For example, the optical disk is configured by a Blu-ray Disc, a CD-RW (Compact Disk ReWritable), a DVD + RW (Digital Versatile Disk ReWritable), or the like. The drive 33 is used when reading data from or writing data to the recording medium 34. The drive 33 records the video data and audio data supplied from the recording processing unit 26 as content on the recording medium 34 and also records title information corresponding to the content on the recording medium 34. At this time, the title list recorded on the recording medium 34 is also updated. The computer program read from the recording medium 34 is stored in the ROM 12 or the nonvolatile memory 15 and installed as necessary.

  1 has been described as receiving a broadcast signal of terrestrial digital broadcasting, but in the case of BS (Broadcasting Satellite) broadcasting, CS (Communications Satellite) broadcasting, or analog broadcasting. Is also applicable. In FIG. 1, the case where the operation of the remote controller by the user is input via the light receiving unit 14 has been described. However, a touch panel is stacked on a display such as an LCD, and an instruction signal from the user is stacked. It is also possible to adopt a configuration in which input is performed via

  FIG. 2 shows a functional configuration example of the signal processing apparatus 1. The functional blocks shown in FIG. 2 are realized by executing a predetermined control program by the CPU 11 of FIG.

  The title information acquisition unit 50 acquires the title information recorded with the content from the title information corresponding to the content to be recorded, or the recording medium 34 among the EPG information stored in the nonvolatile memory 15 or the like, This is supplied to the character string extraction unit 51.

  The title name information is information on the title name set in advance for the recorded content. The title name can be edited (changed) by the user. When the title name is changed by editing, the set title name is added to the title detailed information. Thereby, even if the title name is changed, it can be restored to the set title name. The detailed title information is detailed content information including the broadcast time, outline, and performers related to the content. When the title name is changed, the set title name is added. Note that the title information corresponding to this content may be acquired from a database of a server (not shown) connected to the network or another device via the network interface 31.

  The character string extraction unit 51 extracts a character string from the title information from the title information acquisition unit 50 based on a character string extraction method set in advance by the signal processing device 1, and the extracted character string is converted into a character string. The data is supplied to the registration unit 52 and the related candidate generation unit 54.

  In addition, the character string extraction unit 51 controls the related candidate generation unit 54, the associative character string acquisition unit 56, and the candidate character string reconstruction unit 58 to execute a character string learning process. The character string registration unit 52 outputs a character string extracted by the character string extraction unit 51 as a candidate character string that is a candidate to be output and used on the editing GUI screen when the title name of the content is edited. The candidate character string database 53 is registered. At this time, the character string extraction unit 51 may control the character string registration unit 52 to register the genre information included in the title information of the extraction source together with the candidate character string.

  In the candidate character string database 53, a candidate character string table including information related to candidate character strings extracted by the character string extraction unit 51 and registered by the character string registration unit 52 is recorded.

  The candidate character string table includes a “candidate character string” extracted by the character string extraction unit 51, a “character string extraction method” extracted from the candidate character string, a “related candidate character string” generated by the related candidate generation unit 54, “Associative candidate character strings” acquired by the associative character string acquisition unit 56 from the classified associative character string database (DB) 55 and registered by the associative character string registration unit 57, and candidate character strings are acquired from the candidate character string database 53. "Assignment" syllable "information" and "assignment" line "information" assigned to each of the candidate character strings registered in the candidate character string database 53 (for example, candidate character strings, related candidate character strings, or (Associative candidate character string)) and "priority information".

  In the title information, the related candidate generation unit 54 uses the same symbol (for example, double quotation “”) that is originally adjacent to the extracted candidate character string or the symbol used for the same purpose (for example, the bracket “ ]) Is added to generate a related candidate character string, and the generated related candidate character string is registered in the candidate character string database 53 in association with the candidate character string. For example, when “abc” is included in the title information, abc is extracted as a candidate character string, and “abc” with brackets or “abc” with double quotations is used as a related candidate character string of the candidate character abc. And the generated related candidate character string is registered in the candidate character string database 53 in association with the candidate character string abc.

  The related candidate generation unit 54 also has an adjacent noun adding function that can connect (add) not only symbols but also a character string such as a noun to the candidate character string. That is, the related candidate generation unit 54 determines whether or not it is appropriate when a character string adjacent to the extracted candidate character string is added to the candidate character string in the title information. In this case, the related candidate character string generated by connecting the adjacent character string to the candidate character string is also registered in the candidate character string database 53 in association with the candidate character string.

  The adjacent character string to which the adjacent noun addition function is applied is set in advance, and is not limited to a noun, and may be an adverb or an adjective. Based on the setting, the related candidate generation unit 54 determines whether or not the adjacent character string is appropriate as the candidate character string when concatenated with the candidate character string. These adjacent character strings that are set in advance and symbols to be added to the candidate characters that are used to generate the related candidate character strings are classified associative character string databases 55 and symbol pattern databases 59 described later. Similarly to the above, it may be configured as an additional function database.

  As will be described later in detail with reference to FIG. 5, a record including “classification”, “input character string”, and “output character string” is registered in the associative character string database 55 classified by classification. The classification corresponds to the genre included in the title information, and is used when narrowing the range of the output character string associated with the input character string when searching for candidate character strings. The input character string represents a character string that is a target when a candidate character string is searched from the associative character string database 55 classified by classification. The output character string represents an associative character string associated with the input character string in a certain classification. Also, priority information is added to each of the input character string and the output character string.

  The records of the associative character string database 55 classified by classification are registered in advance, but can be updated by reading from the recording medium 34 distributed by the manufacturer of the signal processing apparatus 1 or the like, and the network interface 31 can be updated. Via a server connected to the Internet or the like. Furthermore, the user himself / herself may previously register an output character string associated with the input character string in a certain classification.

  The associative character string obtaining unit 56 inputs an input that matches the candidate character string from among the “classifications” corresponding to the genres included in the original title information from which the candidate character string is extracted in the associative character string database 55 classified by classification. Search for a character string, obtain an "output character string" corresponding to the "input character string" of the "classification", and use the obtained "output character string" as an associative candidate character string associated with the candidate character string, It supplies to the associative character string registration part 57. The genre information included in the original title information from which the candidate character string is extracted is supplied from the character string extraction unit 51.

  The associative character string registration unit 57 registers the associative candidate character string acquired by the associative character string acquisition unit 56 in the candidate character string database 53. In addition, the associative character string acquisition unit 56, in addition to the “output character string”, “classification” information (that is, genre information) in which “output character string” is searched, and each character string in the classified character string database 55 classified by classification. The priority information added to is also registered in the associative character string registration unit 57.

  The candidate character string reconstruction unit 58 combines the candidate character strings registered by the character string extraction unit 51 based on the character string combination method registered in the symbol pattern database (DB) 59 to obtain a new candidate character. It registers in the candidate character string database 53 as a column. The candidate character string reconstruction unit 58 is registered by the candidate character string registered by the character string extraction unit 51, the related candidate character string registered by the related information candidate generation unit 54, and the associative character string registration unit 57. Each priority of the associated candidate character string is set, and the candidate character string database 53 is reconstructed. At this time, the candidate character string reconstruction unit 58 also refers to the priority information added in the classified associative character string database 55, and each priority of the candidate character string, the related candidate character string, and the associative candidate character string. Set the degree.

  In the symbol pattern database 59, combinations of predetermined symbol patterns that can combine the extracted character strings are registered. For example, when a combination of (character string B) with a parenthesis is registered after “character string A” with brackets in the symbol pattern database 59, the candidate character string reconstruction unit 58 selects the title information. If there is a combination of (character string B) with parentheses after “character string A” with square brackets, “character string A” (character string B), which is a combination of those character strings, is selected as a candidate character. It registers in the candidate character string database 53 as a column.

  The combination method of the symbol pattern database 59 is also registered in advance as in the case of the associative character string database 55 classified by classification. For example, by reading from the recording medium 34 distributed by the manufacturer of the signal processing device 1 or the like, It may be updated, or may be downloaded from a server connected to the Internet or the like via the network interface 31 and updated. Also, the combination method of the symbol pattern database 59 may be registered by the user.

  In the case of the example in FIG. 2, the blocks for registering candidate character strings in the candidate character string database 53 are divided according to the type of candidate character string to be registered. The function for registering the candidate character strings of the character string registration unit 57 and the related candidate generation unit 54 and the candidate character string reconstruction unit 58 may be configured as a single block.

  Next, the character string extraction method of the character string extraction unit 51 will be described in detail with reference to FIGS. 3 and 4 show an example of EPG information that is the basis of title information. 3 and 4, the numbers at the beginning of each line and the colon symbol (:) are added for convenience of explanation, and are not part of the EPG information.

  In the example of FIG. 3, <2004/1/31 (Sat) 9:00 PM-11:30PM 999 OO> on the first line is the content targeted by this EPG information (hereinafter also referred to as target content). ) Broadcast date and time, and broadcast station information. In other words, the first line indicates that the target content is broadcast on the channel 999 of the broadcasting station number 999 from 9:00 pm to 11:30 pm on Saturday, January 31, 2004. Has been. The second row indicates that the name of the target content is <NNN American football -AAA championship->.

  In the third and fourth lines, the outline of the target content is as follows: <"Indianapolis KKK" vs. "New England PPP" [Guest Commentary] *** Husband, [Announcer] △ XX x 1 ~ GGG It shows that the recording is at the stadium. The fifth and sixth lines indicate that the <genre> of the target content is <sports [other ball games]>. The seventh and eighth lines indicate that the <video information> of the target content is composed of <video 1>. The ninth to eleventh lines indicate that the <audio information> of the target content is composed of <first audio / second audio>, and the <audio mode> is <dual monaural>.

  In the example of FIG. 4, <2004/1/31 (Sat) 6:30 PM-7:45PM 000 OO> on the first line is the broadcast date and time of the target content of this EPG information, and broadcast station information Is shown. That is, in the first line, the target content is broadcast on the OO channel of broadcast station number 000 from 6:30 pm to 7:45 pm on Saturday, January 31, 2004. It is shown. The second line indicates that the name of the target content is <Art Entertainment YY Museum>.

  In the third and fourth lines, the outline of the target content is <▽ What is the secret method of the masterpiece “Scream” Munch? ▽ Lecture of genius Dali ▽ YY legend "Mystery of Vermeer"> The fifth to eighth lines indicate that the <genre> of the target content is <documentary [culture / traditional craft] hobby / education [music / art / craft] variety [quiz]>. The ninth and tenth lines indicate that <video information> of the target content is composed of <video 1>. In the 11th to 14th lines, the <audio information> of the target content is composed of <audio 1>, <audio mode> is <stereo>, and <sound quality mode> is <normal mode>. Is shown.

  Here, in the signal receiving device 1, a character string in parentheses, a character string to be delimited, a one-line character string, a character string before the parenthesis, a katakana character string, an alphabetic character string, an alphabetic katakana composite character string, or a character string between parentheses. Is selected as a candidate character string, at least one character string extraction method is set. In addition, when a plurality of character string extraction methods are set, the priority among the plurality of character string extraction methods is also set, and the priority of the character string extracted by the extraction method having a high priority is a candidate. It is set higher by the character string reconstruction unit 58. In the setting of the character string extraction method, the guest commentary and announcer that are characters in brackets [], and the guest commentary and announcer name that follows the character string can be excluded from the extraction target.

  Specifically, the character string in parentheses represents, for example, a character string in parentheses such as a bracket “”, a parenthesis (), a double quotation “”, or a bracket []. Therefore, in the signal receiving device 1, when a character string extraction method for extracting a character string in parentheses as a candidate character string is set, the character string extraction unit 51, for example, within the brackets in the third line in FIG. In Indianapolis · KKK and New England · PPP, the character string in the double quotes in the third row of Fig. 4, and in the brackets in the fourth row of Fig. 4 The mystery of Vermeer, which is a character string, is extracted as a candidate character string.

  In addition, when two strings in parentheses continue as shown in <“Indianapolis / KKK” vs. “New England / PPP”> in the third line of FIG. 3, the middle string (pair) is included. A character string corresponding to two brackets is also extracted as a candidate character string. Further, in this case, a (pair) character between “Indianapolis / KKK” and “New England / PPP” may be extracted as a character string between parentheses and a delimiter.

  The delimiter cut-out character string represents a character string sandwiched between delimiters such as middle black (•), slash (/), dash (−), wave dash (˜), and space (). Therefore, in the signal reception device 1, when the character string extraction method for extracting the delimiter cut-out character string as a candidate character string is set, the character string extraction unit 51, for example, uses the dash ( -) The character string sandwiched between the AAA championship and the character string sandwiched between the wave dashes (~) on the fourth line in FIG. To do.

  At this time, in the character string extraction unit 51, when the above-described character string in parentheses is set as the character extraction method in addition to the delimiter cutout character string, “Indiana” on the third line in FIG. From “polis / KKK”, Indianapolis and KKK are extracted by the brackets “” and the middle black (•).

  A one-line character string is composed of, for example, a line feed, a ▽ mark, and a punctuation mark of a round (.), Comma (,), exclamation mark (!), And question mark (?). Represents a string. Therefore, in the signal receiving device 1, when a character string extraction method for extracting a one-line character string as a candidate character string is set, the character string extraction unit 51, for example, uses a question mark ( The secret method of the masterpiece “Scream” Munch, which is a character string delimited by?), And the genius Dali's xx lecture, which is a character string delimited by the ▽ mark on the third line in FIG. 4 and the YY legend “Mystery of Vermeer” on the fourth line in FIG. 4 is extracted as a candidate character string.

  The character string before the parenthesis represents a character string from the beginning to the parenthesis (raising parenthesis) such as a bracket “”, paren (), double quotation “”, or bracket []. Therefore, in the signal receiving device 1, when the character string extraction method for extracting the character string before the parenthesis as the candidate character string is set, the character string extraction unit 51, for example, uses the key bracket “ The YY legend that is the character string before “is extracted as a candidate character string.

  The katakana character string, the alphabet character string, or the alphabet katakana composite character string is a character string composed of at least one katakana or alphabet. In addition, the middle black (•) between the katakana and katakana, between the alphabet and katakana, or between the alphabet and the alphabet can be a connecting character.

  Therefore, in the signal receiving device 1, when a character string extraction method for extracting a katakana character string, an alphabet character string, or an alphabet katakana composite character string as a candidate character string is set, the character string extraction unit 51, for example, In FIG. 3, the alphabetical katakana composite character string of the second line, NNN American football, the alphabetic character string AAA, and the katakana character string, championship, the alphabetic katakana composite character of the third line The columns, Indianapolis / KKK, and New England / PPP, and the alphabetical katakana composite character string GGG / stadium in the fourth row are extracted as candidate character strings. In FIG. Katakana character strings, Munch, and Dali, list The Vermeer of the fourth row, extracted as a candidate character string.

  The character string between the parentheses represents, for example, a character string between the parentheses such as a bracket “”, a parenthesis (), a double quotation “”, or a bracket []. Therefore, in the signal receiving device 1, when a character string extraction method for extracting a character string between parentheses as a candidate character string is set, the character string extraction unit 51, for example, uses the key bracket “ The character string between “and brackets“ ”is extracted as a candidate character string.

  As described above, the character string extraction unit 51 extracts a character string including at least one character from the title information based on the character extraction method set in the signal receiving device 1.

  Note that the character string extraction method described above is an example, and other extraction methods may be used. In addition to the mechanical character string extraction method described above, a character string can also be extracted by syntax analysis or the like. It is. In the above-described character string extraction method, the parentheses, symbols, or approximants are not limited to those described above, and may be other parentheses, symbols, or approximants.

  FIG. 5 shows a configuration example of the associative character string database 55 classified by classification. As described above with reference to FIG. 2, the classification-related associative character string database 55 includes the classification corresponding to the genre included in the title information, the input character string corresponding to the candidate character string, and the character associated with the input character string. Records consisting of output character strings that are columns are registered.

  In the example of FIG. 5, a record in which the classification is “music”, the input character string is “Vienna”, the output character string is “Austria, the capital of music, Europe” is shown, and the classification is “ Documentary [culture, traditional culture] ”, the input string is“ Munch ”, and the output string is“ Beautiful Master, Edvard Munch, Shouting, Despair, Anxiety ”. Is a record in which “Sports” is input, the input character string is “tennis”, and the output character string is “tournament, final, open”.

  Here, "Austria" in the output string corresponding to the input string "Vienna" is the country name to which Vienna belongs, "City of Music" is the common name of Vienna, and "Europe" is the region to which Vienna belongs. It is. The output character string "Master of Beauty" corresponding to the input string "Munk" is the common name of Munch, "Edvard Munch" is the full name of Munch, and "Scream" is the name of Munch's work "Despair" and "Anxiety" are other works of Munch. “Tournament” in the output string corresponding to the input string “Tennis” is one of the tennis match methods, “Final” is the final final to determine the tennis winner, “Open” is , One of the tennis game formats.

  That is, in the associative character string database 55 classified by classification shown in FIG. 5, the output character string “Austria, the capital of music, Europe” associated with the classification “music” is registered for the input character string “Vienna”. For the string “Munch”, the output string “Master of Beauty, Edvard Munch, Shouting, Despair, Anxiety” associated with the classification “Documentary [Culture, Traditional Culture]” is registered, and the input string “Tennis” ”Is registered as an output character string“ tournament, final, open ”associated with the category“ sports ”.

  Therefore, the associative character string acquisition unit 56, for example, when acquiring the associative candidate character string of the candidate character string “Vienna” extracted from the title information whose genre is “music”, The input character string “Vienna” is searched from the records whose classification is “music”, and the output characters “Austria, city of music, Europe” for the input character string “Vienna” are obtained.

  When the associative character string acquisition unit 56 acquires the associative candidate character string of the candidate character string “Munch” extracted from the title information whose genre is “documentary [culture, traditional culture]”, the associative character string database 55 classified by classification Search the input string “Munch” from among the records whose classification is “Documentary [Culture, Traditional Culture]”, and output character “Munku”, the craftsman of beauty, Edvard Munch, shout To get "despair, anxiety".

  When the associative character string acquisition unit 56 acquires an associative candidate character string of the candidate character string “tennis” extracted from the title information whose genre is “sports”, the classification in the associative character string database 55 classified by category is “ The input character string “tennis” is searched from the record “sports”, and the output character “tournament, final, open” for the input character string “tennis” is acquired.

  As described above, the character string associated with the candidate character string is registered in advance in the associative character string database 55 classified by category, and the associative candidate character corresponding to the candidate character string is stored in the associative character string database 55 classified by category. The column is searched and registered in the candidate character string database 53.

  As a result, when editing the title name of the content, etc., the candidate character string is not included in the title information but also from the candidate character string database 53 based on the content title information. The character string associated with can also be a candidate character string output to the editing GUI screen. Therefore, when editing the title name of the content or the like, a wide variety of candidate character strings are displayed on the editing GUI screen and can be used for editing. That is, user satisfaction can be promoted by the diversity and unexpectedness of the candidate character strings.

  Further, since the output character strings associated with the input character strings are registered for each classification in the classification-related associative character string database 55, the associative character strings corresponding to the candidate character strings to be searched are efficiently searched and acquired. can do. That is, for example, when there is no classification, even if the same input character is “Vienna”, an output character string that is associated with the classification “Liberal Arts [History, Culture]” and is not very suitable for the classification “Music”. (For example, “Hapsburg family”, “Court culture”, etc.) can be prevented from being acquired, thereby improving the search efficiency of the character string.

  In the case of the example shown in FIG. 5, the input character string “Vienna” of the classification “music” has priority over the input character string and output character string of the predetermined classification registered in the associative character string database 55 classified by classification. Priority information is added such that degree = high. That is, in this case, high priority information is added to “Austria, the capital of music, and Europe”, which is the output character string of the input character string “Vienna” of the classification “music”. This priority information is referred to in setting priority by the candidate character string reconstruction unit 58.

  The priority information adding method is not limited to the above method. For example, the priority of the input character string “Vienna” of the classification “music” = high, the priority of the output character string “Austria” = medium, and the output character string “ Priority information may be added to each input character string and output character string such that the priority of “city of music” = high and the priority of output character string “Europe” = low. For example, the priority of the input string “Vienna” for the classification “music” is high, and the priority of the output string “the city of music, Austria, Europe” is registered in the output character string in order from the left to the highest. The priority information may be added in the order in which they are assigned.

  FIG. 6 shows a configuration example of the candidate character string database 53.

  In the case of the example in FIG. 6, the character string extraction method of the candidate character string that is a scream is a character string in parentheses “”, and the related candidate character strings are “scream”, “scream”, and a masterpiece “scream”. The associative candidate strings are Munch, Edvard Munch, Master of Beauty, Despair, Anxiety, and Edvard Munch. Allocation “syllable” information is “sa” and allocation “row” information is “sa line”. It is shown that each priority information of a candidate character string, a related candidate character string, and an associative candidate character string is described as priority information.

  That is, the cry of the candidate character string is extracted from the title information and registered by the character string extraction unit 51 based on the character string extraction method that is the character string in parentheses “”. In this candidate character string, genre information acquired from title information from which the candidate character string is extracted may be registered together with the candidate character string.

  The related candidate character string “scream” is registered by the related candidate generation unit 54 as a related candidate character string by adding the double quotation “” adjacent to the shout in the title information. In the title information, “scream” in the column is registered by the related candidate generation unit 54 as a related candidate character string by adding square brackets “” instead of the double quotation “” adjacent to the shout of the candidate character string. In the title information, the masterpiece “scream” of the related candidate character string is related candidate as a related candidate character string by concatenating the masterpiece that was adjacent to the shout and adding a double quotation “”. It is registered by the generation unit 54.

  The associative candidate character strings Munch, Edvard Munch, Master of Beauty, Despair, Anxiety, and Edvard Munch are extracted from the classified character string database 55 by the associative character string acquisition unit 56, and the title from which the candidate character string is extracted. The input character string and the output character string corresponding to the scream of the classification corresponding to the genre of information are acquired and registered in the candidate character string database 53 by the associative character string registration unit 57 as the associative candidate character string. In addition, in each of these associative candidate character strings, the acquired original classification information and priority information of “input character string” or “output character string” are also registered.

  The assigned “syllable” information indicates that the syllable assigned to the cry of the candidate character string is “S” or “S”. That is, for example, when a key capable of selecting “sa” or “sa” is displayed on the editing GUI screen of the display 28, the “sa” key is selected based on the operation of the user's remote control. Then, the scream of the candidate character string whose allocation “syllable” information is “sa”, and the scream related candidate character string and the associative candidate character string are acquired from the candidate character strings in the candidate character string database 53. The

  Note that the Scream alphabet (T or S) may also be registered in the assigned “syllable” information. Further, when the candidate character string is Munch, the alphabet (M, m) of Munch may be registered in the assignment “syllable” information.

  The assignment “line” information indicates that the syllable assigned to the cry of the candidate character string is a line or a line. That is, for example, “sa” is selected by one remote control operation for one key, “shi” is selected by two consecutive remote control operations for one key, and three consecutive remote control operations for one key are performed. Select “S”, select “SE” by four consecutive remote control operations for one key, and select “SO” by five consecutive operations for one key, that is, according to the number of operations , Keys capable of selecting the five syllables are displayed on the editing GUI screen of the display 28.

  In this case, if the key of the sub-line or the sub-line is selected based on the operation of the user's remote control, the scream of the candidate character string whose assigned “line” information is the sub-line and the related candidate character of the scream A string and an associative candidate character string are acquired from candidate character strings in the candidate character string database 53.

  The candidate character string reconstruction unit 58 sets the priority information of each candidate character string (that is, the candidate character string, the related candidate character string, and the associative candidate character string). Specifically, the priority of each candidate character string is set by the character string extraction method, the number of extractions, or the length of the candidate character string. That is, for example, when a candidate character string is extracted a plurality of times from the title name information and title detailed information of the extraction source, the priority of the candidate character string is set high.

  The candidate character string reconstruction unit 58 determines whether or not the candidate character string is in the associative character string database 55, and if the candidate character string is in the associative character string database 55, the candidate character string reconstructing unit 58 includes the priority included in the associative character string database 55. Based on the degree information, the priority of the candidate character string is set. If the candidate character string is an associative candidate character string, information on the searched classification and priority information on “input character string” or “output character string” are also registered. You can also set the priority.

  Here, as the timing for learning the candidate character strings in the candidate character string database 53 configured as described above, for example, when changing the title name, the folder name, or the media name, the candidates are determined from the target title information. For example, when a character string is learned, or when content is stored in the recording medium 34 (that is, when title information is recorded), learning is performed.

  For example, when learning a candidate character string when editing a folder name, it is necessary to learn the candidate character string for each folder that is instructed to be edited based on the title information of the content managed in the target folder. However, since the target title information is used, it is possible to output more limited candidate character strings in the folder name editing process described later.

  On the other hand, when a candidate character string is learned when content is stored in the recording medium 34 (that is, when title information is recorded), many candidate character strings are output in an editing process such as a folder name described later. Can do. Furthermore, by setting a higher priority for new title information (that is, title information acquired later), a candidate character string related to a newer title name can be output. It is effective when changing However, when changing the folder name described above, the possibility of outputting a limited candidate character string is less than when learning candidate character strings.

  Of course, in the signal receiving device 1, these two learning methods can be used together. For example, when the title information is recorded, the candidate character string A is learned from the title information, and when the folder name is edited later, the priority information of the candidate character string A and the title information belonging to the folder are used. The priority information of the candidate character string A and the candidate character string B is set using two of the acquired priority information of the candidate character string B. Thereby, a candidate character string is output in an order with high priority information among candidate character string A and candidate character string B.

  Next, an example of a character string learning process of the signal reception device 1 will be described with reference to the flowchart of FIG. In the example of FIG. 7, as an example, a case where a candidate character string is learned when title information is acquired from EPG information will be described.

  For example, the user operates the remote controller to instruct recording of desired content. In accordance with a user instruction signal obtained via the light receiving unit 14, the CPU 11 controls the content recording process in each unit of the signal processing device 1.

  The front end unit 22 extracts a broadcast signal corresponding to the user's channel selection from the broadcast signal received via the antenna 21, demodulates it, generates a transport stream, and outputs it to the descrambler 23. The descrambler 23 appropriately de-scrambles the transport stream input from the front end unit 22 and outputs the descrambler 24 to the demultiplexer 24.

  The demultiplexer 24 separates the multiplexed transport stream into a stream such as video or audio data or section data. The demultiplexer 24 outputs the video data and audio data to the recording processing unit 26. On the other hand, the EPG information is received before the content is received or during the content reception, separated by the demultiplexer 24, and stored in the nonvolatile memory 15 or the like by the CPU 11.

  In step S11, the title information acquisition unit 50 acquires title name information and title detailed information corresponding to the content to be recorded among the EPG information stored in the nonvolatile memory 15, and the acquired title name information and title details. The information is supplied to the recording processing unit 26 and is also supplied to the character string extracting unit 51, and the process proceeds to step S12.

  As a result, the recording processing unit 26 performs predetermined processing on the video data and audio data from the demultiplexer 24 and records them as content on the recording medium 34, and also records title name information and title detailed information supplied from the CPU 11. To do.

  In step S12, the character string extraction unit 51 extracts candidate character strings based on a predetermined character string extraction method from at least one of the title name information and the title detailed information from the title information acquisition unit 50, and step S13. It is determined whether or not a candidate character string has been extracted. If it is determined in step S13 that no candidate character string has been extracted, the character string extracting unit 51 ends the learning process because there is no candidate character string to be registered in the candidate character string database 53.

  If the character string extraction unit 51 determines in step S13 that a candidate character string has been extracted, the process proceeds to step S14, where the character string registration unit 52 is controlled to register the extracted candidate character string in the candidate character string database 53. Then, the process proceeds to step S15.

  In step S15, the character string extraction unit 51 controls the related information candidate generation unit 54 to generate a related candidate character string, register the generated related candidate character string in the candidate character string database 53, and in step S16 move on.

  That is, the related information candidate generation unit 54 uses the same symbol (for example, double quotation “”) as that originally adjacent to the candidate character string extracted from the title information, or a symbol used for the same purpose (for example, A related candidate character string is generated by adding brackets “”). In addition, in the title information, the related information candidate generation unit 54 concatenates adjacent character strings when adjacent character strings adjacent to the extracted candidate character strings are appropriate. The generated related candidate character string is also registered in the candidate character string database 53.

  In step S16, the character string extraction unit 51 controls the associative character string acquisition unit 56 to execute the associative candidate character string registration process. This association candidate character string registration process will be described with reference to the flowchart of FIG.

  The associative character string acquisition unit 56 selects one candidate character string from the candidate character strings extracted by the character string extraction unit 51 in step S31 of FIG. 8, and proceeds to step S32. In step S <b> 32, the associative character string acquisition unit 56 selects a candidate character string from “classification” corresponding to the genre included in the original title information from which the candidate character string is extracted in the classified character string database 55. Search for the same input character string, and obtain the "output character string" corresponding to the "input character string" of the "classification", and register the associative character string with the obtained "output character string" as the associative candidate character string Then, the process proceeds to step S33.

  At this time, the associative character string acquisition unit 56, together with “output character string”, “classification” information searched for “output character string”, and priority information of “input character string” or “output character string” Are also supplied to the associative character string registration unit 57. Although illustration is omitted, when the “input character string” corresponding to the candidate character string is not searched, step S33 is skipped, and the process proceeds to step S34.

  In step S <b> 33, the associative character string registration unit 57 associates the associative candidate character string from the associative character string acquisition unit 56 with “classification” information, “input character string”, or “output character string” in association with the candidate character string. Together with the priority information, it is registered in the candidate character string database 53, and the process proceeds to step S34.

  In step S34, the associative character string acquisition unit 56 determines whether or not the processing for all candidate character strings extracted by the character string extraction unit 51 has been completed, and performs processing for all candidate character strings. If it is determined that the process has not ended, the process returns to step S31 and the subsequent processes are repeated. If the associative character string acquisition unit 56 determines in step S34 that the processing for all candidate character strings has been completed, the process returns to step S16 in FIG.

  When the associative candidate character string corresponding to the candidate character string is registered in the candidate character string database 53 in step S16 of FIG. 7, the character string extracting unit 51 proceeds to step S17, and the candidate character string reconstructing unit 58 is set. The candidate character string database 53 is reconstructed based on the symbol pattern database 59, and the character string learning process is terminated.

  Specifically, the candidate character string reconstruction unit 58 combines the candidate character strings registered by the character string extraction unit 51 based on the combination method registered in the symbol pattern database 59 in step S17. The candidate character string database 53 is registered as a new candidate character string.

  The candidate character string reconstruction unit 58 is registered by the candidate character string registered by the character string extraction unit 51, the related candidate character string registered by the related information candidate generation unit 54, and the associative character string registration unit 57. Each priority of the associated candidate character string is set, and the candidate character string database 53 is reconstructed. At this time, the candidate character string reconstruction unit 58 also refers to the priority information added in the classified associative character string database 55, and each priority of the candidate character string, the related candidate character string, and the associative candidate character string. Set the degree. Note that date information included in the title information may also be used for prioritization.

  As described above, in the candidate character string database 53, not only the candidate character strings extracted from the document associated with the title name and folder name to be edited, such as title name information and title detailed information, are registered, Related candidate character strings related to the candidate character strings, associative candidate character strings associated with the candidate character strings, and the like are also registered. That is, each of these candidate character strings can be used for editing in a title name or folder name editing process to be described later, so that the operability of user character input can be improved.

  Further, in the example of the signal receiving device 1, a candidate character string is extracted not from the EPG information itself but from the title name information and title detailed information of the content corresponding to the editing target (title name and folder name). Registration of candidate character strings not to be registered in the candidate character string database 53 is suppressed.

  In the example of FIG. 7, it has been described that character string learning processing is performed when content is recorded, but is not limited to content recording, for example, when the user is not viewing content. For example, before editing the folder name, only the title information of the content recorded in the folder to be edited is targeted. Alternatively, only the title information to be edited is edited before editing the title name. It can also be done. It is also possible to perform a learning process in advance for each title information of the folder.

  For example, when learning is performed collectively when the user is not viewing the content (that is, when the load on the signal processing device 1 is low), the load on the signal processing device 1 can be reduced, as described above. In the case of learning by restricting the target before editing the title name or folder name, it is possible to output more limited candidate character strings in the folder name editing process.

  In the above description, at least one of the associative character string database 55 classified by classification, the symbol pattern database 59, and the additional function database described above with reference to FIG. 2 is connected via a network. (For example, a server 301 connected to the network 303 in FIG. 14 described later).

  For example, when all these databases are configured in the server, the associative character string acquisition unit 56, candidate character string reconstruction unit 58, and related candidate generation unit 54 of the signal processing device 1 are respectively separated via the network. By accessing the associative character string database 55, the symbol pattern database 59, and the additional function database, data in each database is acquired.

  As described above, the classification-related associative character string database 55, the symbol pattern database 59, or the additional function database is arranged on the server, so that the database can be configured on a large scale, and the users can be various. Can be obtained. Further, unlike the case where the signal processing apparatus 1 is configured as described above, it is not necessary to update the associative character string database 55 and the symbol pattern database 59 according to classification, and the signal processing apparatus 1 reduces the processing load. The

  Next, content title name and folder name editing processing performed using the candidate character string database 53 registered as described above will be described. In the following description, candidate character strings, related candidate character strings, and associative candidate character strings registered in the candidate character string database 53 may be collectively referred to as candidate character strings or candidate character strings as appropriate. is there.

  FIG. 9 shows another functional configuration example of the signal processing device 1. The functional blocks shown in FIG. 9 are realized by executing a predetermined control program by the CPU 11 of FIG.

  The edit control unit 101 controls the candidate character string acquisition unit 102 and the display data generation unit 103 in accordance with a user instruction signal obtained via the light receiving unit 14, and the title name of the content and the folder name in which the content is recorded And processing for editing the media name of the recording medium 34 and the like.

  Specifically, the editing control unit 101 controls the candidate character string acquisition unit 102 based on the title information corresponding to the target to be edited (title name, folder name, media name, etc.), and the candidate character string database. The candidate character string is acquired from 53, or the priority of the candidate character string is changed. The editing control unit 101 also controls the display data generation unit 103 to generate editing GUI screen data corresponding to a user instruction signal obtained via the light receiving unit 14.

  The candidate character string acquisition unit 102 acquires candidate character strings from the candidate character string database 53 based on the title information supplied from the edit control unit 101, and the order of the highest priority set in the candidate character string database 53. Alternatively, based on the control of the editing control unit 101, the priority set in the candidate character string database 53 is changed, and the information on the candidate character strings is displayed in the order of the changed priority. To the display data generation unit 103.

  The display data generation unit 103 generates editing GUI screen data reflecting the editing GUI screen data according to the control of the editing control unit 101 or the candidate character string supplied from the candidate character string acquisition unit 102, The generated editing GUI screen data is supplied to the reproduction processing unit 27, and an editing GUI screen corresponding to the user operation is displayed on the display 28 in real time.

  FIG. 10 shows an example of the edit GUI screen.

  In the example of FIG. 10, the editing GUI screen 121 includes, for example, a software keyboard 131, a character input area 132, a candidate display area 133, a save key 134, an end key 135, and the like. The save key 134 is a key used when changing the title name and closing the edit GUI screen 121. The end key 135 is a key used to close the editing GUI screen 121 without changing the title name.

  The software keyboard 131 has a character key 141 composed of 50 sounds (syllables) for inputting (displaying) characters in the character input area 132, an input switching key 142 for switching hiragana, katakana, and alphabet, and a candidate display area 133. A genre key 143 used when selecting a genre (classification) of a candidate character string to be displayed, a character deletion key 144 used when deleting a character displayed in the character input area 132, and a space in the character input area 132. Space key 145 used when displaying (inputting), Cancel key 146 used when returning the character string displayed in the character input area 132, selecting or determining the character string displayed in the character input area 132 The decision key 147 and the like used in this case are used. The character key 141 is not limited to 50 sounds, and is composed of characters that can input all syllables.

  In addition, an arrow 151 is displayed on the edit GUI screen 121. The arrow 151 moves based on the user's remote control operation and indicates the operation position to the user. Specifically, when the operation position is not on the software keyboard 131, the character input area 132, the candidate display area 133, or various keys that are the operation targets, the operation position is indicated by an arrow 151. In addition, when the arrow 151 (operation position) is moved over any of the operation targets by the user's remote control operation, the operation target is selected and becomes an operable state to indicate the operable state to the user. The color of the operation target is reversed or the arrow 151 becomes a cursor.

  In the character input area 132, a syllable (that is, a character string consisting of one character) corresponding to a character key instructed by a user's remote control operation, and a target to be edited (such as a title name and a folder name) are displayed. In the case of the example of FIG. 10, the character input area 132 displays a song “Don Giovanni” having a title name preset in the recorded content as an object to be edited.

  In the candidate display area 133, a candidate character string, a related candidate character string, and an associative candidate character string corresponding to the character string displayed in the character input area 132 or selected in the character input area 132 are displayed. For example, when a folder name is changed, a candidate character string obtained from a plurality of target title information (that is, title information of content managed in the folder to be changed) is displayed.

  In the case of the example of FIG. 10, the candidate display area 133 includes a candidate character string acquired from the candidate character string database 53 based on the title name in the character input area 132 and the title information of the content of the play “Don Giovanni”. , Related candidate character strings, and associative candidate character strings (1 DON GIOVANNI, 2 Don Giovanni, 3 Mozart, 4 opera,...) Are displayed in the descending order of priority set in the candidate character string database 53. . In FIG. 10, the numbers shown in the candidate display area 133 only indicate the high priority, and may not actually be present.

  The user operates the remote controller to select a candidate character string to be displayed in the candidate display area 133, thereby adding the selected candidate character string to the character input area 132 or selecting it in the character input area 132. Can be replaced with the selected candidate character string.

  Next, a title name editing method will be described with reference to FIGS. 11 and 12 show display examples of the character input area 132 of FIG.

  The display of the editing GUI screen (character input area 132 and candidate display area 133) described below is supplied from the candidate character string acquisition unit 102 by the display data generation unit 103 under the control of the editing control unit 101. Edit GUI screen data is generated according to the information (priority) of the candidate character string to be generated, and the generated edit GUI screen data is supplied to the reproduction processing unit 27 and displayed on the display 28. For convenience of explanation, the explanation is omitted.

  In the example of FIGS. 11 and 12, a cursor 161 is shown in the character input areas 132c, 132d, 132f, and 132i, and an area selection 171 is made in the character input areas 132b, 132e, 132g, and 132h. The string is shown.

  For example, when the arrow 151 (operation position) is moved on the character input area 132 by the user's remote control operation and the character input area 132 becomes operable, the character input area 132c, 132d, As shown by 132f and 132i, the arrow 151 turns into a cursor 161. For example, in the character input area 132, when the cursor 161 is in a predetermined condition, the character string is area-selected 171 and the candidate display area is displayed. The display order of the 133 candidate character strings is changed.

  That is, when a predetermined condition is satisfied that the cursor 161 is positioned at the head of the candidate character string obtained by the candidate character string acquisition unit 102 among the character strings such as the title name displayed in the character input area 132, As shown in the character input areas 132b, 132e, 132g, and 132h, the character string is area-selected 171 and the priority of the candidate character strings displayed in the candidate display area 133 according to the area selection 171 The candidate character strings are displayed in the order of the priority of the changed priority in the candidate display area 133. As a result, due to the limitation of the number of displays on the screen, the character string that has not been displayed may be changed in priority and displayed.

  Hereinafter, a specific description will be given in order from the character input area 132a.

  For example, when the user operates the remote control to instruct editing of the recorded title “Don Giovanni” with the title name set in advance, the editing processing unit 101 displays the candidate character string acquisition unit 102. The candidate character string acquired from the title information of the content to be controlled and whose title name is to be edited is obtained from the candidate character string database 53. Specifically, the candidate character string acquisition unit 102 obtains, for example, DON GIOVANNI, Don Giovanni, opera, Mozart, drama, opera, “Don Giovanni” with parentheses, Don Giovanni, Find candidate strings such as dong. Of these, DON GIOVANNI, Don Giovanni, drama, Mozart, and opera are associative candidate character strings.

  Accordingly, the opera “Don Giovanni” is displayed in the character input area 132a, and the candidate display area 133 is displayed in the order of the priority set in the candidate character string database 53, for example, as shown in FIG. Thus, candidate character strings such as DON GIOVANNI, Don Giovanni, Mozart, Opera,... Are displayed. Hereinafter, this display order (order with the highest priority set in the candidate character string database 53) is set as the first priority order.

  Here, when the arrow 151 in FIG. 10 is moved on the character input area 132a by the user's remote control operation, as shown in the character input area 132b, a candidate character string called the opera at the beginning of the title name is displayed in the area Selected 171 and displayed. In the candidate display area 133, candidate character strings are displayed in the order of the character string selected in the area 171 and the priority level changed based on the opera. When there is no candidate character string at the head, the arrow 151 is displayed as the cursor 161 at the head of the title name.

  Next, in the character input area 132b, the user operates the direction key of the remote controller one right. Thereby, the character string / opera area selection 171 is canceled, and as shown in the character input area 132c, a cursor 161 indicating the insertion position is displayed immediately before the character string / opera. Then, when the area selection 171 is canceled, the candidate character strings displayed in the candidate display area 133 are displayed in the candidate character string database 53 in the order of the priority level changed based on the opera. Return (change) to the set first priority order.

  In the character input area 132c, the user further operates the direction key of the remote controller one more to the right. Thereby, as shown in the character input area 132d, the cursor 161 indicating the insertion position is displayed between the character string and the opera (between the song and the play). At this time, the display order of the candidate character strings displayed in the candidate display area 133 does not change from the first priority order.

  Further, in the character input area 132d, the user operates the direction key on the remote controller one right. Then, as shown in the character input area 132e, “Don Giovanni”, which is the next candidate character string with parentheses (related candidate character string) in the title name, is selected and displayed in the area selection 171. In the candidate display area 133, the candidate character strings are displayed in the order of the priority changed based on the character string selected in the area 171 and "Don Giovanni". At this time, in the character input area 132g described later, the candidate character string, Don Giovanni, is set to have a higher priority for the character string with parentheses than when the area selection 171 is performed.

  Next, in the character input area 132e, the user operates the directional key on the remote controller one right. This cancels the area selection 171 of the character string “Don Giovanni” and inserts it immediately before the character string “Don Giovanni” (immediately after the character string, the opera) as shown in the character input area 132f. A cursor 161 representing the position is displayed. When the area selection 171 is canceled, the display order of the candidate character strings displayed in the candidate display area 133 is returned to the first priority order set in the candidate character string database 53.

  In the character input area 132f, the user operates the direction key of the remote controller one right. Then, as shown in the character input area 132g, Don Giovanni, which is the next candidate character string in the title name, is selected and displayed in the area selection 171. In the candidate display area 133, the candidate character strings are displayed in the order of the character string selected in the area 171 and the priority level changed based on Don Giovanni. At this time, in the character input area 132e, the parenthesized candidate character string “Don Giovanni” is set to have a higher priority for the character string without parentheses than when the area selection 171 is performed.

  In the character input area 132g, the user operates the direction key of the remote controller one right. Then, as shown in the character input area 132h, a don, which is the next candidate character string in the title name, is selected by area 171 and displayed. In the candidate display area 133, the candidate character strings are displayed in the descending order of priority changed based on the character string selected in the area selection 171 and the don.

  In the character input area 132h, the user operates the direction key on the remote controller one right. As a result, the character string / don area selection 171 is canceled, and a cursor 161 representing the insertion position is displayed immediately before the character string / don as shown in the character input area 132i. When the area selection 171 is canceled, the display order of the candidate character strings displayed in the candidate display area 133 is returned to the first priority order set in the candidate character string database 53.

  In addition, after this, when the user operates the direction key of the remote controller to the right by one, the same processing as described above is repeated. That is, in the character input area 132, when the cursor 161 is placed at the head of a candidate character string, a related candidate character string, or an associative candidate character string, the combined character string is selected as an area 171. Then, in a state where the character string has been area-selected 171, the area selection 171 is canceled and the cursor 161 is displayed by further operating the direction key of the remote controller one right. Such processing is repeatedly executed.

  On the other hand, in the candidate display area 133, when the character string is not selected in the area 171 in the character input area 132, the candidate character strings are displayed in the first priority order set in the candidate character string database 53. When the column is area-selected 171, the candidate character strings related to the character string selected in the area selection 171 are displayed in a high display order (priority) according to the change in the priority based on the character string selected in the area selection 171. (In order according to the degree information) or only relevant candidate character strings are displayed.

  In addition, by using the genre key 143 shown in the example of FIG. 10, the candidate character string, the related candidate character string, and the associative candidate character string displayed in the candidate display area 133 according to the genre information of each character string. It is also possible to change the display order by limiting the priority of candidate character strings, related candidate character strings, and associative candidate character strings displayed in the candidate display area 133 in advance.

  Although not shown, the title name can also be edited using the character key 141.

  For example, in the character display area 132, when the cursor 161 is displayed immediately after the opera “Don Giovanni” (that is, after the receiving bracket), the user operates the remote controller to select “ When the character key 141 corresponding to “a” (in this case, “” is added to explain the syllable, a) is selected in the character display area 132, the character string (syllable) “ "Is selected and displayed in the area selection 171. Then, candidate character strings are displayed in the candidate display area 133 in the order of the priority changed based on “A”. At this time, for example, in the candidate character string database 53, the priority of the candidate character string, the related candidate character string, and the associative candidate character string whose allocation “syllable” information is “A” is set high.

  In the character display area 132, when the character selection 141 corresponding to “I” on the soft keyboard 131 is selected by the user operating the remote control while “A” is the area selection 171, the character is displayed. In the display area 132, the character string “Ai” is selected and displayed in the area 171. Then, candidate character strings are displayed in the candidate display area 133 in the order of the priority changed based on “Ai”. At this time, for example, in the candidate character string database 53, the priority of the candidate character string, the related candidate character string, and the associative candidate character string that include the character string “Ai” or that is related to the character string “Ai” is set high. Is done.

  Further, in the character display area 132, when the character selection 141 corresponding to “ko” on the soft keyboard 131 is selected by the user operating the remote control in a state where “ai” is the area selection 171, In the display area 132, the character string “Aiko” is selected and displayed in the area 171. Then, candidate character strings are displayed in the candidate display area 133 in the order of the priority changed based on “Aiko”. At this time, for example, in the candidate character string database 53, the character string “Aiko” is included or the priority of the candidate character string, the related candidate character string, and the associative candidate character string related to the character string “Aiko” is set high. Is done.

  As described above, the candidate character string is acquired from the candidate character string database 53 and changed based on the character string selected in the character input area 132 based on the title information of the content associated with the editing target. They are displayed in the candidate display area 133 in descending order of priority.

  That is, in the candidate display area 133, the candidate character strings are displayed in the order of priority according to the character string selected in the character input area 132. Therefore, for the user, the character string selected in the character input area 132 and The hit rate for finding a candidate character string to be replaced in the candidate display area 133 is increased. Therefore, it can be easily changed to a desired character string.

In addition, when inputting a character using the character key 141 described above, when a candidate character string displayed in the candidate display area 133 is changed, for example, a predictive conversion function such as POBox (registered trademark) is used together. It may be. In this case, the candidate character string and the predicted character string by the prediction conversion function are displayed side by side in the candidate display area 133. That is, the candidate character string (including the predicted character string) displayed in the candidate display area 133 is displayed based on the priority information of the candidate character string and the priority information of the predicted character string.

  Next, an example of an editing process such as a title name by the signal processing apparatus 1 will be described with reference to the flowchart of FIG. In FIG. 13, the case of editing the title name of the content will be described. However, the same processing is executed for folder names, media names of recording media, label names such as tags, or other character editing. .

  For example, the user operates the remote controller to instruct editing of the title name of the recorded content. In step S71, the editing control unit 101 supplies the title information of the content to be displayed displayed in the character input area 132 to the candidate character string acquisition unit 102, and the process proceeds to step S72.

  In step S72, the edit control unit 101 controls the candidate character string acquisition unit 102 to acquire candidate character strings registered in the candidate character string database 53 based on the title information (title name information and title detailed information). In step S73, the display data generation unit 103 is controlled to generate and generate editing GUI screen data for editing the title name of the content according to the user instruction signal obtained via the light receiving unit 14. The video corresponding to the editing GUI screen data is displayed on the display 28, and the process proceeds to step S74.

  Specifically, in step S72, the candidate character string acquisition unit 102 acquires each candidate character string registered in the candidate character string database 53 based on the title information from the editing control unit 101, and the candidate character string Information of each candidate character string is supplied to the display data generation unit 103 in descending order of priority set in the database 53.

  In step S <b> 73, the display data generation unit 103 displays the title name in the character input area 132 under the control of the editing control unit 101, and each candidate character string has a priority order from the candidate character string acquisition unit 102. Then, the editing GUI screen data displayed in the candidate display area 133 is generated, and the generated editing GUI screen data is supplied to the reproduction processing unit 27. The reproduction processing unit 27 causes the display 28 to display a video corresponding to the supplied editing GUI screen data. Thereby, for example, the editing GUI screen 121 of FIG. 10 is displayed on the display 28.

  The user operates the remote controller while viewing the editing GUI screen 121, so that the arrow 151 is moved to the software keyboard 131, the character input area 132, the candidate display area 133, and various keys that are the operation targets on the editing GUI screen 121. By moving the cursor over any one of these, one of the operation objects is selected, and the character displayed in the character input area 132 is edited.

  Based on the user instruction signal obtained via the light receiving unit 14, the editing control unit 101 determines in step S 74 whether or not there is a user editing instruction on the editing GUI screen 121, and the editing GUI screen 121 is displayed. If it is determined that there is no user editing instruction, the process proceeds to step S82. If the editing control unit 101 determines in step S74 that there is a user editing instruction on the editing GUI screen 121, the editing control unit 101 proceeds to step S75, and the user editing instruction is a character input area selection instruction. It is determined whether or not.

  For example, as described above with reference to FIG. 11, when the user moves the arrow 151 onto the character input area 132 by operating the remote controller, the editing control unit 101 edits the user in step S75. In step S76, the candidate character string acquisition unit 102 is controlled, and the candidate acquired in step S72 is determined. The high priority of the character string is changed based on the character string selected in the area selection 171 and the process proceeds to step S77.

  For example, when a character input area is selected for the first time in step S76, the candidate character string acquisition unit 102 selects the first candidate character string extracted from the title name information (title name) (that is, the character string selected for the area selection 171). Based on (for example, the opera in the character input area 132b in FIG. 11), the priority level of the candidate character string acquired in step S72 is changed, and the information on each candidate character string is changed in descending order of priority. Is supplied to the display data generation unit 103. In the subsequent step S76, as described above with reference to FIG. 11 and FIG. 12, the candidate character string acquisition unit 102 changes to the first priority order when no area is selected based on the user's remote control operation. Or when the area is selected, the priority level of the candidate character string is changed based on the candidate character string to be extracted next (area selected).

  In step S77, the edit control unit 101 controls the display data generation unit 103 so that each candidate character string is displayed in the candidate display area 133 in the order of priority supplied from the candidate character acquisition unit 102, and Edit GUI screen data is generated so that a predetermined candidate character string of the title name in the character display area 132 is displayed in the area selected state 171, and a video corresponding to the generated edit GUI screen data is displayed on the display 28. Then, the process proceeds to step S78.

  Thereby, candidate character strings are displayed in the candidate display area 133 of the editing GUI screen 121 in the order in which the priority is changed based on the character string selected in the area selection 171 in the character input area 132. For example, here, the user operates the remote controller to move the arrow 151 and select a desired character string from the candidate display area 133 of the editing GUI screen 121.

  In step S78, the edit control unit 101 determines whether a candidate character string has been selected based on a user instruction signal obtained via the light receiving unit 14, and determines that the candidate character string has been selected. In step S79, the display data generation unit 103 is controlled to generate edit GUI screen data in which the selected candidate character string is reflected in the character input area 132, and an image corresponding to the generated edit GUI screen data is displayed. 28, and proceeds to step S80.

  That is, in this case, in the character input area 132, the character string selected in the area selection 171 is displayed in place of the candidate character string selected by the user in the candidate character string area 133.

  Furthermore, in step S80, the edit control unit 101 determines whether another candidate character string is selected based on a user instruction signal obtained via the light receiving unit 14, and selects another candidate character string. When it determines with having been carried out, it returns to step S79 and the process after it is repeated. That is, in the character input area 132, the character string selected in the area selection 171 is displayed in place of the other candidate character string selected by the user in the candidate character string area 133.

  If it is determined in step S80 that no other candidate character string is selected, the process proceeds to step S82. If it is determined in step S78 that no candidate character string is selected, steps S79 and S80 are skipped, and the process proceeds to step S82.

  On the other hand, if it is determined in step S75 that the user's editing instruction is not a character input area selection instruction, that is, an instruction to an operation target other than the character input area, the editing control unit 101 performs step S75. Proceeding to S81, the display data generation unit 103 is controlled to generate editing GUI screen data reflecting a user instruction signal obtained via the light receiving unit 14, and a video corresponding to the generated editing GUI screen data is displayed. 28, and proceeds to step S82.

  Specifically, for example, the user moves the arrow 151 onto the software keyboard 131 that is the operation target on the editing GUI screen 121 by operating the remote controller while viewing the editing GUI screen 121, and the software keyboard is displayed. If 131 is selected, the edit control unit 101 edits GUI screen data obtained by inverting the display color of the software keyboard 131 so that the display data generation unit 103 indicates that the software keyboard 131 has been selected in step S81. And the generated editing GUI screen data is displayed.

  In step S <b> 82, the edit control unit 101 determines whether to end editing based on a user instruction signal obtained via the light receiving unit 14. For example, when the save key 134 is selected or the end key 135 is selected, the editing control unit 101 determines that the editing process is to be ended, and causes the display data generation unit 103 to stop displaying the editing GUI screen, End the editing process.

  Specifically, for example, when the user operates the remote controller to move the arrow 151 onto the save key 134 and select the save key 134, the editing control unit 101 selects the save key 134. Therefore, it is determined that the editing process is ended, the title name is changed to a character string displayed in the character input area 132, the set title name is added to the title detailed information, and then the display data generation unit 103 is changed. Then, the display of the editing GUI screen is stopped, and the editing process is terminated.

  Alternatively, for example, when the user operates the remote controller to move the arrow 151 onto the end key 135 and select the end key 135, the editing control unit 101 selects the end key 135, The editing control unit 101 causes the display data generation unit 103 to stop displaying the editing GUI screen without changing the title name, and ends the editing process.

  On the other hand, if the user does not select the save key 134, the end key 135, and the like and it is determined in step S82 that the editing is not to be ended, the editing control unit 101 returns to step S74 and repeats the subsequent processing. In step S82, it may be determined that the editing is to be terminated when the input of the instruction signal from the user has not elapsed for a predetermined time.

  In the example of FIG. 13, a case has been described in which candidate character strings are learned and registered in the candidate character string database 53. For example, as described above, when editing a title name or the like, candidate characters are used. When learning a candidate character string registered in the column database 53, the candidate registered in the candidate character string database 53 is executed after the learning process described with reference to FIG. Processed to get a string.

  As described above, each candidate character string is acquired from the candidate character string database 53 and displayed based on the title name information and title detailed information of the target (title name or folder name of the content) that the user wants to edit. The user can edit a desired title name simply by selecting the displayed candidate character string. That is, the user can save time and effort to select (input) one character from the character key 141 by operating the remote controller or the like, and the operability of the user's character input can be improved.

  The display order of the candidate character strings displayed in the candidate character area 133 is changed according to the priority level set based on the character string selected in the character input area. As a result, a candidate character string that is more related to the selected character string can be displayed above the candidate character area 133, which improves the operability for the user.

  Further, in the candidate character string database 53, not only the candidate character strings acquired from the title name information and the title detailed information, but also related candidate character strings related to the character strings, and associative candidate characters associated with the candidate character strings. Columns are also registered and displayed in the candidate character area 133.

  Specifically, when the user selects a character string or cry in the character input area 132, in the example of FIG. 4 described above, candidates acquired from title name information and title detailed information such as cry and munch. In addition to the strings, as shown in Fig. 6, Munk's full name "Edvard Munch", alphabetical title "Edvard Munch", Munk's popular name "Beauty Master", etc. It is displayed in the character area 133. Therefore, the user can select a desired character string or an unexpected character string related to the content content simply by inputting characters related to the content content. That is, user satisfaction can be promoted by the diversity and unexpectedness of candidate character strings.

  In the candidate display area 133, the character strings are displayed in the order of the priority set from the length of the candidate character string, the number of appearances, the genre, or the priority information registered in the associative character string database 55 classified by classification. Therefore, it is possible to suppress the misplaced character string from being displayed at the top of the candidate display area 133, for example.

  In the above description, the priority of each candidate character string is set based on the priority information registered in the associative character string database 55 classified by classification, but in the symbol pattern database 59 or FIG. The priority information may be registered in advance in the additional function database described above, and the priority of each candidate character string may be set based on the priority information.

  Further, in the above description, a character string is acquired and learned from EPG information (title name information and title detailed information) of content associated with the folder name, title name, and media name to be edited, and the folder name, title name The case of editing the media name has been described. For example, when a character string is acquired from an e-mail received via the network interface 31 and learned, and a reply e-mail associated with the received e-mail is created. Further, for example, when editing a folder name or a media name for managing a document, a character string from a document or text data stored in the folder or medium (that is, associated) May be acquired, learned, and used.

  In the above description, the signal receiving device 1 has been described. However, the present invention can be applied not only to the signal receiving device but also to a portable terminal such as a PDA (Personal Digital assistant) or a mobile phone. Of course, the present invention can also be applied to a personal computer having a keyboard. Furthermore, the present invention is not limited to a single device but can be applied to an information processing system connected via a network shown in FIG.

  FIG. 14 shows the configuration of an information processing system to which the present invention is applied. In FIG. 14, a server 301 is connected to a signal receiving apparatus 302 via a network 303 such as the Internet or an intranet.

  The signal reception device 302 is configured in the same manner as the hardware configuration of the signal reception device 1, and for example, implements other than the candidate character string database 53 in the functional blocks of FIG. That is, it is assumed that the server 301 has the candidate character string database 53 in the example of FIG. In other words, in the case of the example of FIG. 14, the candidate character string acquisition unit 102 is different from the signal receiving apparatus 1 only in that the candidate character string acquisition unit 102 accesses the candidate character string database 53 included in the server 301 via the network 303.

  The candidate character string acquisition unit 102 of the signal reception device 302 executes the editing process of FIG. 13 via the network 303 when editing the folder name or the title name of the content. That is, the candidate character string acquisition unit 102 transmits the target title information recorded in the built-in storage unit 32 to the server 301 via the network 303. For example, in the case of a folder name, all title information corresponding to the content managed in the target folder is transmitted.

  Correspondingly, each candidate character string acquired in the candidate character string database 53 is transmitted from the server 301 via the network 303 as candidate character string information together with priority information. When receiving the candidate character string information, the signal reception device 302 generates editing GUI screen data based on the priority information from the server 301, and displays a video corresponding to the generated editing GUI screen data on the display 28. .

  Further, the candidate character string acquisition unit 102 of the signal receiving device 302 also converts the character string selected in the character input area 132 by the user's operation as described above with reference to FIG. Accordingly, the priority level of the candidate character strings displayed in the candidate character area 133 can be changed, and therefore the display order can be changed according to the priority.

  On the other hand, the server 301 has the same configuration as that of the signal receiving device 1 of FIG. 1 except that the processing unit (for example, the antenna 21 to the speaker 29) that receives signals is omitted. For example, the function block of FIG. In addition, a functional block to which the candidate character string acquisition unit 102 of FIG. 9 is added is realized.

  When the server 301 receives the title information from the signal reception device 302 via the network 303, the server 301 executes the learning process described above with reference to FIG. That is, the server 301 acquires a candidate character string from the title information, registers it in the candidate character string database 53, and further obtains a related candidate from the classified associative character string database 55 or the additional function database described above with reference to FIG. Character strings, associative candidate character strings, and the like are registered in the candidate character string database 53, priorities are added to the candidate character strings based on the symbol pattern database 59, and the candidate character string database 53 is reconstructed.

  Then, the candidate character string acquisition unit 102 of the server 301 acquires each candidate character string from the reconstructed candidate character string database 53 based on the title information from the signal receiving device 302, and together with the priority information, the network The interface 31 is controlled to cause the signal reception device 302 to transmit via the network 303.

  As a result, in the signal reception device 302, an edit GUI screen including a candidate character area 133 in which candidate character strings are arranged in order based on the priority information from the server 301 is displayed on the display 28.

  As described above, the present invention acquires candidate character strings from the title information from the user of the signal receiving apparatus 302, reconstructs the candidate character string database 53, and gives the user of the signal receiving apparatus 302 the candidate character strings, The present invention can also be applied to a server 301 that provides a service for transmitting a candidate character string including a related candidate character string, an association candidate character string, and the like.

  Thereby, for example, in the signal reception device 302, the load of calculation processing for constructing the character string database 53 is reduced. Therefore, it is effective when the signal receiving device 302 is composed of a portable terminal or the like and the processing capability is small.

  Furthermore, in the information processing system of FIG. 14, the server 301 may implement the functional blocks of FIG. 9 in addition to the functional blocks of FIG. That is, in this case, the signal processing device 302 accesses the server 301 using browser software or the like, and transmits title information and the like. Then, the display data generation unit 103 of the server 301 generates edit GUI screen data corresponding to the browser software, and transmits it to the signal processing device 302 via the network 303. As a result, the signal processing device 302 displays an editing GUI screen on which candidate character strings are displayed in order of priority.

  Of course, as described above, in the signal processing apparatus 1 of FIG. 2, the classified associative character string database 55, the symbol pattern database 59, or the additional function database described above with reference to FIG. 2 is connected via a network. You may make it comprise in a server. In this case, the database can be configured with a large scale, and the user can acquire a wide variety of candidate character strings.

  As described above, in the information processing system in FIG. 14, each of the functional blocks in FIGS. 2 and 9 includes the processing capability of the signal reception device 302, the performance of the network 303, and the processing capability of the server 301. It may be installed in either the signal receiving device 302 or the server 301 according to the above.

  The series of processes described above can be executed by hardware, but can also be executed by software. When a series of processing is executed by software, a program constituting the software may execute various functions by installing a computer incorporated in dedicated hardware or various programs. For example, it is installed from a program storage medium in a general-purpose personal computer or the like.

  As shown in FIG. 1, a program storage medium that stores a program that is installed in a computer and can be executed by the computer is a magnetic disk (including a flexible disk), an optical disk (CD-ROM (Compact Disc-Read). Recording media (package media) 34 or a program made up of a semiconductor memory or the like, or a program is temporarily stored in the memory (including only memory), DVD (digital versatile disc), magneto-optical disc (including MD (mini-disc) (trademark)) It is configured by a ROM 12 or the like that is stored permanently or permanently.

  In the present specification, the steps shown in the flowcharts include not only processes performed in time series according to the order described, but also processes executed in parallel or individually even if not necessarily performed in time series. Is included.
