Description

  The present invention relates to a recording apparatus, method, and program, and more particularly, to a recording apparatus, method, and program that can make remote recording reservation of a program simpler and at a lower cost.

  In recent years, there has been known a remote recording reservation system in which a user can instruct a recording reservation of a program to a recording apparatus installed at a remote place by operating a mobile phone or a personal computer.

  For example, as shown in FIG. 1, such a remote recording reservation system includes a recording device 11, a personal computer 12, and a mobile phone 13, and each of the recording devices 11 to 13 is connected via a communication network 14. Are connected to each other.

  The recording device 11 is installed in a user's house, for example, and has a server function. The user can make a reservation for remote recording of a program by operating the personal computer 12 or the mobile phone 13 while away from home. That is, the personal computer 12 or the mobile phone 13 accesses the recording device 11 via the communication network 14 and calls the recording reservation function of the recording device 11 in accordance with a user operation.

  When the user operates the personal computer 12 or the mobile phone 13 to specify a program to be recorded, the personal computer 12 or the mobile phone 13 receives information indicating the program specified by the user according to the user's operation. The data is transmitted to the recording device 11 via the communication network 14.

  On the other hand, the recording device 11 receives information indicating a program transmitted from the personal computer 12 or the mobile phone 13, reserves recording of the program indicated by the received information, and records the program reserved for recording. When the broadcast time comes, the program is received and recorded.

  In such a remote recording reservation system, the user only has to operate the personal computer 12 or the mobile phone 13 to directly access the recording device 11, so that the remote recording reservation system implements the remote recording reservation system. No other device that provides network services is required. Therefore, since the cost required to realize the remote recording reservation system is only the development cost of the software installed in the recording apparatus 11, the manufacturer of the recording apparatus 11 provides the user with a remote recording reservation service at a low cost. can do.

  In some remote recording reservation systems, as shown in FIG. 2, remote recording reservation is performed via a server 21 that provides a network service. In FIG. 2, the same reference numerals are given to the portions corresponding to those in FIG. 1, and the description thereof will be omitted as appropriate.

  In the example of FIG. 2, a server 21 is newly connected to the communication network 14, and when the user operates the personal computer 12 or the mobile phone 13 to specify a program to be recorded, the personal computer 12 or the mobile phone 13. Transmits information indicating a program designated by the user to the server 21 via the communication network 14 in accordance with the user's operation.

  When information indicating a program is transmitted from the personal computer 12 or the mobile phone 13, the server 21 receives and stores the information indicating the transmitted program. Then, the recording device 11 periodically accesses the server 21, acquires information indicating the program stored in the server 21, and reserves recording of the program indicated by the acquired information.

  As described above, in the remote recording reservation system in which the recording device 11 and the personal computer 12 or the mobile phone 13 exchange information indicating a program to be recorded via the server 21, the recording device 11 has a predetermined communication network. 14, the number of items to be set by operating the recording device 11 for the user to make a remote recording reservation is small compared to the example of the remote recording reservation system shown in FIG. The user can easily make a remote recording reservation.

  In addition, since the personal computer 12 and the mobile phone 13 that are operated to make a remote recording reservation need only access the predetermined server 21, the user can use these devices as devices to be operated at the time of remote recording reservation. You can easily make the settings necessary to

  Further, in the conventional remote recording reservation system, a recording device installed in a user's home is set in a predetermined format required for recording a program from a private server connected via a network provided in the user's home. There is also a program that reserves recording reservation information and reserves recording of a program based on the acquired information (see, for example, Patent Document 1). In this remote recording reservation system, a public server receives and stores recording reservation information input by a user transmitted from a mobile phone, and a private server records from a public server connected via the Internet. Get reservation information.

  However, in the above-described remote recording reservation system in which the personal computer or mobile phone directly accesses the recording device, the recording device realizes a server function, and thus measures against unauthorized access to the recording device from the outside are required. In addition, in order for devices such as personal computers and mobile phones used for remote recording reservation to directly access the recording device, many settings such as various network settings are required from the user. Therefore, the user is required to have detailed knowledge about the network, and the user has to make complicated settings.

  In a remote recording reservation system in which a recording device and a personal computer or a mobile phone exchange information indicating a program to be recorded via a server, a user can make settings necessary for remote recording reservation relatively easily. However, since it is necessary to provide a dedicated server in the remote recording reservation system, a large amount of cost is required for installing the server and maintaining the service provided by the server.

  Furthermore, even in a remote recording reservation system in which the recording device acquires recording reservation information from a public server via a private server, only a large amount of cost is required for installing the private server and the public server and maintaining the service. In addition, since the user has to input recording reservation information in a predetermined format, remote recording reservation could not be made if the user did not know the information to be input as recording reservation information accurately. .

  The present invention has been made in view of such a situation, and makes it possible to make a remote recording reservation easily and at low cost.

  The communication unit 91 communicates with the server 62 via the communication network 64 to exchange various data. The blog article acquisition unit 92 acquires a blog article or the like from the server 62 via the communication unit 91. The blog article acquisition unit 92 includes a setting information recording unit 111, an acquisition unit 112, and an article generation unit 113.

  The setting information recording unit 111 records setting information that is various kinds of information necessary for acquiring an article of a blog posted by a user from the server 62 and posting an article to the server 62. The acquisition unit 112 acquires the setting information from the setting information recording unit 111, and using the acquired setting information, the RSS (Rich Site) including the update date of the blog, the article summary, and the like from the server 62 via the communication unit 91. Summary) Get feeds, blog posts, and more. The acquisition unit 112 supplies the acquired blog article to the analysis processing unit 93.

  Further, the acquisition unit 112 transmits the article supplied from the article generation unit 113 to the server 62 via the communication unit 91. Furthermore, the acquisition unit 112 includes a determination unit 121, and the determination unit 121 determines whether or not the blog has been updated based on the acquired RSS feed. When the program recording reservation completion notification is supplied from the program search unit 94, the article generation unit 113 generates an article including a message indicating that the recording reservation has been made, and supplies the article to the acquisition unit 112.

  The analysis processing unit 93 extracts information for specifying a program to be reserved for recording from the article supplied from the acquisition unit 112 and supplies the information to the program search unit 94. The analysis processing unit 93 includes a word dictionary recording unit 114, a word string detection unit 115, and an extraction unit 116.

  The word dictionary recording unit 114 records a word dictionary in which a predetermined detection target word is registered. The word string detection unit 115 refers to the word dictionary recorded in the word dictionary recording unit 114 and refers to the word registered in the word dictionary for the article supplied from the acquisition unit 112 (hereinafter appropriately registered). The word string is detected from the character string included in the article, that is, the article body. Further, the word string detection unit 115 supplies the word string detection result to the extraction unit 116.

  The extraction unit 116 performs analysis processing, understands the contents of the word string supplied from the word string detection unit 115, extracts information for specifying a program from the word string, and supplies the information to the program search unit 94. That is, the extraction unit 116 uses the date and time specified by the word representing the date and time among the words included in the word sequence supplied from the word sequence detection unit 115 as time information indicating the broadcast date and time of the program, and relates to the contents of the program. The word is supplied to the program search unit 94 as a keyword.

  The program search unit 94 refers to the program distribution information recorded in the recording unit 97 and searches for a program specified by the time information and the keyword supplied from the extraction unit 116. Here, the program distribution information refers to information indicating a broadcast schedule of a program composed of information indicating a program, for example, EPG (Electronic Program Guide). The information indicating each program includes information indicating the broadcast date and time of the program and information regarding the contents of the program. That is, more specifically, the program search unit 94 searches for information indicating a program specified by time information and a keyword from information indicating programs included in the program distribution information, and indicates the program obtained as a result. The program specified by the information is a program for which recording is reserved.

  The program search unit 94 instructs the recording control unit 96 to record the program obtained as a result of the search, and reserves the recording of the program. Further, for the program reserved for recording, the program search unit 94 supplies the article generation unit 113 with a recording reservation completion notification including information related to the program.

  The receiving unit 95 includes a tuner and the like, receives a program broadcasted by a television station and a program distribution information from a broadcast station (not shown), and supplies the program control unit 96 with the program. Further, iEPG (Internet EPG) or the like may be acquired as program distribution information from a device to which the receiving unit 95 is connected via the communication network 64.

  The recording control unit 96 supplies the program distribution information supplied from the receiving unit 95 to the recording unit 97 for recording. In addition, the recording control unit 96 supplies the recording unit 97 with the program instructed to be recorded by the program searching unit 94 among the programs supplied from the receiving unit 95. The recording unit 97 includes, for example, a hard disk drive, and records programs and program distribution information supplied from the recording control unit 96.

  Incidentally, the recording device 63 periodically accesses the server 62 connected via the communication network 64, and performs a recording reservation process for making a recording reservation for the program. Hereinafter, recording reservation processing by the recording device 63 will be described with reference to the flowchart of FIG.

  In step S11, the recording device 63 performs an article acquisition process. Although details of the article acquisition process will be described later, in this article acquisition process, the recording device 63 generates a blog article, RSS feed, blog information, and the like based on the setting information recorded in the setting information recording unit 111. get. Here, the blog information is information necessary for posting and obtaining the article. The blog information includes a URL (Uniform Resource Locator) for accessing the user's blog, a blog ID for identifying the blog, a blog title, etc. It is included. When the blog article is acquired, the acquired article is supplied from the acquisition unit 112 to the word string detection unit 115.

  In step S12, the analysis processing unit 93 performs an analysis process. Although details of the analysis processing will be described later, in this analysis processing, the analysis processing unit 93 uses time information and information as information for specifying a program from an article supplied from the acquisition unit 112, that is, a character string included in the article. The keywords are extracted and supplied to the program search unit 94.

  In step S <b> 13, the program search unit 94 searches for a program for which recording is scheduled based on the time information and keywords supplied from the extraction unit 116 of the analysis processing unit 93. More specifically, the program search unit 94 includes the date and time indicated by the time information among the information indicating the program included in the program distribution information recorded in the recording unit 97 as the broadcast date and time of the program, and Information indicating a program in which a keyword is included in information related to the contents of the program is searched as information indicating a program to be reserved for recording. Here, the information indicating the program includes information indicating the broadcast date and time of the program and information regarding the content of the program, and the information regarding the content of the program includes the word regarding the program such as the content of the program, the title, and the performer. It is included.

  In addition, although it has been described that time information and a keyword are used as information for specifying a program, a program to be reserved for recording may be searched using only the time information or the keyword. For example, when only one of the time information and the keyword can be extracted in the analysis processing unit 93, the program search unit 94 searches for a program using the extracted time information or keyword.

  In step S14, the program search unit 94 determines whether there is a program for which recording is reserved. That is, the program search unit 94 determines whether or not there is one or more programs obtained as a result of the search.

  If it is determined in step S14 that there is no program that is scheduled to be recorded, since the user has not instructed recording of the program, the process proceeds to step S18.

  On the other hand, if it is determined in step S14 that there is a program to reserve recording, the process proceeds to step S15, and the program search unit 94 reserves recording of the program. In other words, the program search unit 94 reserves recording of these programs by instructing the recording control unit 96 to record all the programs obtained as a result of the search. As a result, the program reserved for recording is recorded at the broadcast time. That is, the recording control unit 96 acquires the program reserved for recording from the receiving unit 95 and causes the recording unit 97 to record it. Also, the program search unit 94 supplies the article generation unit 113 with a recording reservation completion notification including information related to the program reserved for recording.

  In step S <b> 16, the article generation unit 113 generates an article including a message indicating that a program recording reservation has been made based on the completion notification from the program search unit 94, and supplies the article to the acquisition unit 112.

  In step S17, the acquisition unit 112 posts the article supplied from the article generation unit 113 to the blog. That is, the acquisition unit 112 supplies the article supplied from the article generation unit 113 to the communication unit 91, and the communication unit 91 transmits the article supplied from the acquisition unit 112 to the server 62 via the communication network 64. .

  More specifically, for example, when the Web public API (Application Program Interface) provided by the server 62 is in the XML-RPC (Extensible Markup Language-Remote Procedure Call) format, the acquisition unit 112 sets the setting information and the blog. Using the information, a request message for calling a method called blogger.newPost or a method called metaWeblog.newPost is generated. This request message includes an API key used for authentication when an article is entered, a blog ID, a user name, a password, an article supplied from the article generation unit 113, information specifying whether or not to publish the article, and the like. include.

  Here, which method of the blogger.newPost or metaWeblog.newPost is called by the acquisition unit 112 is determined depending on which method the server 62 providing the blog service supports. Further, when metaWeblog.newPost is called, the recording device 63 can add a title to the article. Therefore, when the server 62 can handle both blogger.newPost and metaWeblog.newPost, metaWeblog.newPost To be called.

  For example, when the Web public API format provided by the server 62 is the AtomAPI format, the acquisition unit 112 obtains a get request message for the PostURI (Uniform Resource Identifier) acquired from the server 62 in the process of step S11. An article can be posted by generating and sending a request message such as a post request message. Here, the transmitted request message includes a user name, password, article, article title, and the like.

  In this way, the request message generated by the acquisition unit 112 is transmitted to the server 62 via the communication unit 91. When the Web public API format provided by the server 62 is the AtomAPI format, when the server 62 receives a request message from the recording device 63, the server 62 uses the user name and password included in the request message. Perform WSSE authentication.

  If an article is posted in step S17 or if it is determined in step S14 that there is no program to reserve recording, the recording device 63 determines in step S18 whether or not to end the process. For example, when the user operates the recording device 63 and gives an instruction to turn off the power, the recording device 63 determines to end the process.

  If it is determined in step S18 that the process is not to be ended, the recording is continuously reserved, so the process returns to step S11 and the above-described process is repeated.

  On the other hand, if it is determined in step S18 that the processing is to be terminated, the recording device 63 terminates the processing performed by each unit, and the recording reservation processing is terminated.

  In this way, the recording device 63 acquires a blog article from the server 62, and extracts time information and keywords for specifying a program from the acquired article. Then, the recording device 63 searches for a program to be recorded based on the extracted time information and keywords and schedules recording.

  As described above, the server 62 that provides the blog service is accessed, the blog article is acquired and the recording is reserved, so that the network device necessary for accessing the server 62 from the recording device 63 and the terminal device 61 is provided. Various settings can be made easily. In addition, since a remote recording reservation can be performed using a general free blog service, it is not necessary to start a service dedicated to remote recording reservation, and the server 62 also requires software dedicated to remote recording reservation. Therefore, a remote recording reservation service can be provided at a low cost.

  Also, since the blog service itself assumes writing from any terminal device, by searching for the program to be recorded and reserving recording based on the time information and keywords extracted from the blog article, As long as the terminal device can be connected to the communication network 64 and can post a blog article, the recording of the program can be reserved for any terminal device. Therefore, for example, a user can make a remote recording reservation only by posting an article instructing remote recording reservation for one line on a train to a blog using a mobile phone as the terminal device 61.

  Furthermore, by using a general web service called a blog, it is possible to make a remote recording reservation not only using a blog posted by the user itself but also using a blog article written by another person. In this embodiment, even if an article of a blog posted by another person is not intended to be reserved for recording, if time information and keywords are extracted by analysis processing, recording is reserved from the contents of the blog. Therefore, it is possible to reflect not only the user but also the taste of others in the recording reservation.

  Next, the article acquisition process corresponding to the process of step S11 of FIG. 5 will be described with reference to the flowchart of FIG.

  In step S <b> 41, the acquisition unit 112 acquires setting information from the setting information recording unit 111. Here, the setting information includes, for example, a blog service name that identifies an entity that provides a blog service, a Web public API call URL for article posting, a Web public API call URL for image posting, a user name, a password, API key and URL to get RSS feed are included.

  Web publishing API call URL for article posting and web publishing API call URL for image posting included in the setting information are provided for each blog service to allow users to use the web publishing API. It is a URL for calling a method, and is a unique character string for each blog service.

  When the Web public API format is XML-RPC, the Web public API call URL for article posting and the Web public API call URL for image posting are the same. It only needs to include the URL of the web public API call. When the Web public API format is the AtomAPI format, each of the Web public API call URL for article posting and the Web public API call URL for image posting corresponds to the root end point.

  Furthermore, the user name, password, and API key are information necessary for posting an article on a blog, and are a unique character string for each user.

  Such setting information is set by the user when the recording device 63 is initially set. For example, the user selects one blog service name from several blog service names by operating the recording device 63 while viewing a setting screen displayed on a display device (not shown) connected to the recording device 63. . When the blog service name is selected by the user, the recording device 63 internally stores the character string indicating the selected blog service name among the plurality of character strings indicating the blog service names recorded in advance. get.

  In addition, the user operates the recording device 63 while viewing the setting screen, and Web posting API call URL for article posting, Web public API call URL for image posting, user name, password, API key, and RSS feed URL Enter. The recording device 63 records the input information as setting information. Corresponding to the blog service name selected by the user by associating the blog service name with the Web public API call URL for article posting, the Web public API call URL for image posting, and the RSS feed URL in advance. Web public API call URL and RSS feed URL may be recorded as setting information.

  When the acquisition unit 112 acquires the setting information, in step S42, the acquisition unit 112 acquires blog information. For example, when the Web publishing API format is XML-RPC format, the acquisition unit 112 generates a request message for calling a method called blogger.getUsersBlogs, as shown in FIG. The API call URL is sent to the server 62 via the communication unit 91 as a destination. This request message includes the user name and password included in the setting information.

  When the server 62 receives the request message from the recording device 63, the server 62 calls a method according to the request message, and includes the URL for accessing the blog, the blog ID, and the blog title as the blog information. Response message is generated and transmitted to the recording device 63 via the communication network 64.

  Then, the communication unit 91 receives the response message transmitted from the server 62 and supplies the response message to the acquisition unit 112, and the acquisition unit 112 acquires blog information from the response message supplied from the communication unit 91.

  Depending on the blog service, the user may be able to use a plurality of blogs for one set of user name and password. In such a case, in response to the request message for calling blogger.getUsersBlogs transmitted from the recording device 63 to the server 62, the server 62 determines the number of blogs specified by the user name and password included in the request message. A response message including the URL for accessing the blog, the blog ID, and the blog title is transmitted to the recording device 63.

  Therefore, in the recording device 63, the user can set one blog to be used for the remote recording reservation by setting the blog to be used for the remote recording reservation in advance when setting the setting information. That is, the acquisition unit 112 of the recording device 63 acquires, as setting information, a set including the blog ID set by the user from among a plurality of sets of URLs, blog IDs, and blog titles for accessing the blog. .

  On the other hand, when the Web public API format is the AtomAPI format, as shown in FIG. 7B, the acquisition unit 112 generates a get request message including the user name and password as setting information, and That is, the generated get request message is transmitted to the server 62 via the communication unit 91, with the article public web API call URL for posting as a destination.

  When the server 62 receives the get request message from the recording device 63, the server 62 performs WSSE authentication using the user name and password included in the get request message. A response message including the PostURI and FeedURI is generated and transmitted to the recording device 63 via the communication network 64.

  Then, the communication unit 91 receives the response message transmitted from the server 62 and supplies it to the acquisition unit 112. The acquisition unit 112 acquires PostURI and FeedURI as blog information from the response message supplied from the communication unit 91. To do. Here, PostURI is a URL for calling a method for posting an article on the user's blog, and FeedURI is a URL for calling a method for acquiring an article on the user's blog.

  As described above, when the blog information is acquired from the server 62, the preparation for posting the article to the blog or acquiring the article is completed.

  Returning to the description of the flowchart of FIG. 6, in step S <b> 43, the acquisition unit 112 accesses the position indicated by the URL of the RSS feed as the setting information, and acquires the RSS feed from the server 62. For example, the acquisition unit 112 transmits a transmission request for requesting transmission of the RSS feed recorded at the position indicated by the URL of the RSS feed to the server 62 via the communication unit 91, and the server 62 includes the recording device 63. The transmission request from is received.

  Then, the server 62 transmits the RSS feed requested by the transmission request to the recording device 63 via the communication network 64. The communication unit 91 of the recording device 63 receives the RSS feed transmitted from the server 62 and supplies it to the acquisition unit 112.

  In step S44, the determination unit 121 of the acquisition unit 112 determines whether or not the blog has been updated based on the acquired RSS feed. That is, the determination unit 121 determines whether a new article has been posted. For example, the determination unit 121 stores the date and time when the RSS feed was last referenced, and performs determination by comparing the stored date and time with the update date and time included in the acquired RSS feed. .

  If it is determined in step S44 that the blog has not been updated, the process returns to step S43, and the above-described process is repeated. The acquisition unit 112 acquires the RSS feed from the server 62, for example, at a frequency of several to several tens of times a day. Therefore, for example, when the process returns from step S44 to step S43, the acquisition unit 112 acquires a new RSS feed after a predetermined time has elapsed since the last acquisition of the RSS feed.

  On the other hand, if it is determined in step S44 that the blog has been updated, the process proceeds to step S45, and the acquisition unit 112 accesses the server 62 and acquires a newly posted blog article. Then, the acquisition unit 112 supplies the acquired article to the word string detection unit 115, and the process proceeds to step S12 in FIG.

  For example, when the Web public API format is XML-RPC format, the acquisition unit 112 generates a request message for calling a method called blogger.getRecentPosts or a method called metaWeblog.getRecentPosts, and the blog To the server 62 via the communication unit 91. Then, the server 62 receives the request message transmitted from the recording device 63, calls a method in accordance with the request message, generates a response message including the blog article requested to be transmitted, The data is transmitted to the recording device 63 via the communication network 64.

  The communication unit 91 receives the response message transmitted from the server 62 and supplies the response message to the acquisition unit 112. The acquisition unit 112 acquires the blog article from the response message supplied from the communication unit 91.

  Depending on the blog service, only one of the methods of blogger.getRecentPosts or metaWeblog.getRecentPosts can be used to acquire a blog article, or both methods can be used. Which method is to be used is determined in advance according to the corresponding method in 62.

  When the Web public API format is the AtomAPI format, the acquisition unit 112 generates a get request message including the user name and password as the setting information with the FeedURI acquired as the blog information as a destination, and the communication unit 91 To the server 62 via

  When the server 62 receives the get request message from the recording device 63, the server 62 performs WSSE authentication using the user name and password included in the get request message. When the authentication is successful, transmission is requested. A response message including the user's blog article is generated and transmitted to the recording device 63 via the communication network 64.

  The communication unit 91 receives the response message transmitted from the server 62 and supplies the response message to the acquisition unit 112, and the acquisition unit 112 acquires the blog article from the response message supplied from the communication unit 91.

  In this way, the recording device 63 acquires the RSS feed from the server 62, determines whether or not the blog has been updated, and acquires the article of the blog when the blog is updated.

  As described above, the RSS feed is acquired from the server 62 to determine whether or not the blog has been updated, and when the blog is updated, the article of the blog is acquired. You can easily schedule remote recording by simply posting an article that includes the date and time and words related to the contents of the program.

  Further, any blog service provided in general may be used to make a remote recording reservation, so that the user who is the owner of the recording device 63 keeps the blog that he / she uses as it is. You can make remote recording reservations. As a result, more users can make remote recording reservations more easily without depending on a specific blog service.

  Next, analysis processing that is processing corresponding to the processing in step S12 in FIG. 5 will be described with reference to the flowchart in FIG.

  In step S71, the word string detection unit 115 processes the article supplied from the acquisition unit 112, more specifically, the character string of the article body. For example, the word string detection unit 115 converts a full-width character number or a Chinese character included in the article body into a half-width character number, or an unnecessary symbol included in the article body, such as HTML (Hyper Text Markup). Edit the text string of the article text by deleting the tags used in the description in the (Language) format and the characters in the tags.

  In step S72, the word string detection unit 115 refers to the word dictionary recorded in the word dictionary recording unit 114, and compares the registered word registered in the word dictionary with respect to the processed character string of the article body. Pattern matching is performed to detect a word string from the article body.

  For example, the word dictionary shown in FIGS. 9 and 10 is recorded in the word dictionary recording unit 114. In the word dictionary shown in FIG. 9 and FIG. 10, a word representing a date and time, a word representing a recording reservation operation, a word whose part of speech is a particle, and the like are registered, and the registered word registered in the word dictionary Includes its registered word readings, part of speech, meaning, and value.

  Here, “word” is a template for detecting a registered word from a character string to be analyzed, and “reading” indicates reading of the registered word. “Part of speech” indicates the part of speech of the registered word, and “Meaning” indicates the type of word for understanding the content of the sentence indicated by the target character string in the analysis process, that is, the registered word indicates the date and time. The type of the word, such as whether it is a word to represent or a word to represent a recording reservation operation, is shown. Further, “value” indicates information required to convert the date and time indicated by the word into a numerical value representing the date and time.

  That is, in the word dictionary, the word “today” having a reading “Kyo”, a part of speech “noun”, a meaning “date designation”, and a value “current date” is registered. The word “today”, whose reading is “honjitsu”, the part of speech is “noun”, the meaning is “date / time designation”, and the value is “current date”, is registered.

  In the word dictionary, the word “Tomorrow” whose reading is “Tomorrow, Tomorrow”, the part of speech is “Noun”, the meaning is “Specify Date / Time”, and the value is “Current Date + 1 Day”. The word “Tomorrow”, which is registered, has the reading “Asa, Myo Nichi”, the part of speech is “Noun”, the meaning is “Specify date and time”, and the value is “Current date + 2 days” Is registered, the reading is “Shisatte”, the part of speech is “noun”, the meaning is “date and time designation”, and the value “current date + 3 days” is registered. ing.

  Here, for example, the reading “Asatte, Myounichi” of the word “the day after tomorrow” indicates that the reading of the word is “Asatte” or “Myogo Nichi”, and the meaning “date designation” It indicates that the word “day after tomorrow” is a word designating a date as a date and time, and the value “current date + 2 days” is the current date, that is, the word string detection unit 115 or the extraction unit 116 performs processing. It shows the date two days after the date on which the word dictionary was referred to.

  In the word dictionary, the word “This week” has the reading “Konshu”, the part of speech “Noun”, the meaning “Weekly specified”, and the value “Saturday of the same week from the current date”. ”Is registered, the reading is“ Raishu ”, the part of speech is“ Noun ”, the meaning is“ Weekly specified ”, and the value is“ One week after Sunday of next week ” "Next week" is registered, the reading is "Raigetsu", the part of speech is "noun", the meaning is "month specified", and the value is "current month + 1 month" "Is registered.

  In addition, the word dictionary contains the word “Sunday” with the reading “Nichiyo”, the part of speech “noun”, the meaning “day of the week”, and the value “Sunday”. , The word “Monday” with the reading “Getsuyo”, the part of speech “Noun”, the meaning “Day of the week” and the value “Monday” is registered, and the reading is “Kayo” ”, The part of speech is“ noun ”, the meaning is“ day of the week designation ”, and the value“ Tuesday ”is registered as a word“ Tuesday ”.

  Furthermore, in the word dictionary, the word “Wednesday” whose reading is “Suiyo”, the part of speech is “noun”, the meaning is “day of week designation”, and the value is “Wednesday” is registered. The word “Thursday” with the reading “Mokuyo”, the part of speech “Noun”, the meaning “Day of the week”, and the value “Thursday” is registered, and the reading is “Kin” ”, Part-of-speech is“ noun ”, meaning“ day-of-the-week ”is specified, and the word“ Friday ”with the value“ Friday ”is registered. The word “Saturday”, which is “noun”, meaning “day designation”, and value “Saturday”, is registered.

  Furthermore, the word “recording” having a reading “Rokuga”, a part of speech “noun”, and a meaning “reservation / recording execution” is registered in the word dictionary. ”, Part of speech is“ verb ”, meaning“ schedule / record execution ”is registered, word“ sue ”is registered, reading is“ want ”, part of speech is“ verb ”, meaning The word “I want to” that is “Reservation / Recording execution” is registered, the reading is “To”, the part of speech is “Verb”, and the meaning is “Reservation / Recording execution”. Is registered.

  Here, for example, the meaning “reservation / recording execution” of the word “te” indicates that the word represents a recording reservation operation.

  Similarly, in the word dictionary, the word “shiro” whose reading is “shiro”, the part of speech is “verb”, and whose meaning is “reservation / recording execution” is registered, and the reading is “take”. Yes, the part of speech is “verb”, the word “record” with the meaning “reservation / recording execution” is registered, the reading is “take”, the part of speech is “verb”, and the meaning is “ The word “recording”, which is “reservation / recording execution”, is registered.

  Also, as shown in FIG. 10, the word “I want to record” is registered in the word dictionary with the reading “I want to take”, the part of speech “verb”, and the meaning “reservation / recording execution”. The word “I want to see” is registered, the reading is “To”, the part of speech is “verb”, the meaning “reservation / recording execution” is registered, the reading is “to”, and the part of speech is The word “to”, which is “participant”, has the meaning “and”, is registered, has the reading “o”, the part of speech is “particle”, and the meaning “noun designation” "" Is registered.

  Here, for example, the meaning “and” of the word “to” indicates that it is a word used when arranging nouns of the same rank, and the meaning “designation of the noun” of the word “to” is arranged immediately before. This indicates that the word specifies a noun.

  In the word dictionary, the word “ka” whose reading is “ka”, the part of speech is “particle”, the meaning “or” is registered, the reading is “no”, and the part of speech is The word “no”, which is “particle”, has the meaning “own”, is registered, has “ni” as the reading, has the part of speech as “particle”, and has the meaning “designation of time”. "" Is registered.

  Here, for example, the meaning “or” of the word “ka” indicates that either the word immediately before or the word immediately after the word may be selected. The meaning “time designation” indicates that the word immediately before the word is designated as a word representing the date and time.

  Furthermore, in the word dictionary, a word “nn year” having a reading “Nen”, a part of speech “noun”, a meaning “year designation”, and a value “nn year” is registered. , The word “nn month”, whose reading is “tsuki”, the part of speech is “noun”, the meaning is “month designation”, the value is “nn month”, and the reading is “hi” , The part of speech is “noun”, the meaning is “date designation”, the word “nn day” having the value “nn day” is registered, the reading is “ji”, and the part of speech is “ "Noun", meaning "time designation", value "nn hour" is registered word "nn hour", reading is "fun", part of speech is "noun", meaning Is “minute specification”, and the word “nn minutes” having the value “nn minutes” is registered.

  Here, the letters nn in the words “nn year”, “nn month”, “nn day”, “nn hour”, and “nn minutes” indicate arbitrary numerical values.

  Note that the purpose of the analysis processing performed by the analysis processing unit 93 is to specify what the user wants to record, and not to understand the contents of general sentences. In the example of the word dictionary shown in FIG. 10, only words that are specialized for recording a program, that is, words that specify, for example, the broadcast date of the program or indicate the recording operation are registered in the word dictionary.

  Further, in a general natural sentence understanding method, morphological analysis is sometimes performed to classify the use of verbs. In the examples of FIGS. 9 and 10, the used verbs are also registered as one word. In this way, by only registering words for specifying a program to be recorded in the word dictionary, the number of words to be referred to can be reduced, and analysis processing can be performed more quickly.

  In the word dictionary recording unit 114, the word dictionary shown in FIGS. 9 and 10 is recorded. In step S <b> 72, the word string detection unit 115 refers to the word dictionary recorded in the word dictionary recording unit 114, and performs pattern matching with the registered word registered in the word dictionary with respect to the character string of the article text. I do.

  For example, the word string detection unit 115 uses the registered word itself and the reading of the registered word as a word for pattern matching with respect to the character string of the article body so that a word described in hiragana can also be detected. Pattern matching is performed between words and character strings in the article text. That is, the word string detection unit 115 not only performs pattern matching between the registered word itself and the character string of the article text, but also reads the registered word as one word, and the word and the character string of the article text. Also performs pattern matching.

  Here, the word string detection unit 115 selects a registered word registered in the word dictionary, more specifically, a registered word and a registered word having a large number of characters from among the readings of the registered word, and sequentially selects the article text. If the character string that matches the registered word is detected and the character string that matches the registered word is detected, the character string is assumed to be the same word as the registered word, and the meaning of the character string that does not match the registered word is unknown. Let the part of speech be a noun word.

  When the word string detection unit 115 performs pattern matching between a registered word representing a time such as year, month, day, hour, minute, and second and a character string of the article body, the word string detection unit 115 Of the characters in the body of the article that are the same as the characters excluding any number nn in the character string constituting the registered word, such as “hour” and “minute” included in the registered word representing Only when there is a single-byte character number immediately before, the word consisting of those numbers and the character immediately after the number included in the article body is a word representing time, and "hour", " If there is no single-byte character immediately before a character such as “minute”, it is not regarded as a word representing time.

  Thus, for example, as shown in FIG. 11, the word strings “Today”, “To”, “Tomorrow”, “No”, “Soccer”, “I want to see” from the character string “I want to see football today and tomorrow”. Is detected. Here, in the figure of each word constituting the detected word string, the part of speech and meaning of the word are shown on the lower side. For example, under the word “Today”, the part of speech “noun” and the meaning “date designation” are shown, and under the word “soccer”, the part of speech “noun” and the meaning of the word are unknown. The meaning “unknown” indicating a word is shown.

  When a word string is detected by pattern matching, the word string detection unit 115 supplies the detection result to the extraction unit 116.

  Returning to the flowchart of FIG. 8, when pattern matching with the registered word is performed, the extraction unit 116 detects the word string detected based on the word string detection result supplied from the word string detection unit 115 in step S <b> 73. The time information and keywords are extracted as information for specifying the program from the word string. Then, the extraction unit 116 supplies the extracted time information and keywords to the program search unit 94, and the process proceeds to step S13 in FIG.

  For example, according to the following six rules, the extraction unit 116 understands the content of the word string from the positional relationship of each word, and extracts time information and keywords.

(1) Rule 1
The word “to” positioned between the nouns has a meaning of “and” and is used when arranging nouns of the same rank.
(2) Rule 2
A word “ka” positioned between nouns has a meaning of “or”, and is a word indicating that either the word immediately before or the word immediately after the word may be selected.
(3) Rule 3
The word “NO” located immediately after the noun representing the date and time is a word representing possession.
(4) Rule 4
When nouns representing date and time are consecutive, these nouns represent one date and time.
(5) Rule 5
The noun immediately preceding the word “O” is a keyword that identifies the program.
(6) Rule 6
The noun immediately preceding the verb whose meaning is “reservation / recording execution” is a keyword that identifies the program.

  The extraction unit 116 extracts time information and keywords from the word string according to these six rules. Further, when extracting the time information and the keyword from the word string, the extraction unit 116 uses a word representing the date and time whose meaning is “date designation”, “day designation”, and the like by using the word “value”. Replace with a number indicating the date and time shown.

  For example, when the current date and time is January 1, 2006, the extraction unit 116 replaces the word “today” with a numerical value representing January 1, 2006 using the value “current date”, and the word “ “Tomorrow” is replaced with a value representing January 2, 2006, using the value “current date + 1 day”.

  In addition, when the date and time indicated by the detected word is a date and time outside the period of the program broadcast schedule indicated by the program distribution information recorded in the recording unit 97, the date and time indicated by the word is invalid. It is not time information.

  In addition, for example, the current date and time is June 20, 2006, and the word string supplied to the extraction unit 116 includes the word “tomorrow”, the word “no”, and the word “19:00” in order. In this case, in accordance with rule 3, the extraction unit 116 sets the word “Tomorrow” representing the date and time, the word “no”, and the word “19:00” representing the date and time as a word string representing one date and time. The date and time is defined to mean “19:00 on June 21, 2006”. That is, the extraction unit 116 extracts time information indicating the date and time “19:00 on June 21, 2006” from the word string as the detection result.

  For example, the current date and time is June 20, 2006, and the word “tomorrow”, the word “no”, and the unknown word “drama” are sequentially arranged in the word string supplied to the extraction unit 116. In accordance with Rule 3, the extracting unit 116 is a word related to the contents of the program, the word “tomorrow” representing the date and time and the word “drama” of unknown meaning immediately after the word “no” representing possession. And That is, the extraction unit 116 extracts the keyword “drama” from the word string as the detection result.

  Further, for example, the current date and time is June 20, 2006, and the word string “Today” indicating the date and time and the word “19:00” indicating the date and time are sequentially arranged in the word string supplied to the extraction unit 116. If it is included, the extraction unit 116 converts the word “today” and the word “19:00” into a word string representing one date and time according to the rule 4, and the date and time “June 20, 2006” from the word string as the detection result. 19:00 "is extracted.

  Furthermore, for example, when the word string supplied to the extraction unit 116 includes the unknown word “drama”, the word “O”, and the word “I want to see” in order, the extraction unit 116. Follows the rule 5 and extracts the unknown word “drama” immediately before the word “o” as a keyword.

  Further, for example, in the word string supplied to the extraction unit 116, the word “drama” with an unknown meaning and the word “reserve” in which the meaning is “reservation / recording execution” and the part of speech is a verb are sequentially ordered. In the case where they are included in a line, the extraction unit 116 assumes that the word “ha” for designating a noun is omitted immediately before the word “reserved” and the word “reserved” immediately before the word “reserved” according to rule 6. An unknown word “drama” is extracted as a keyword.

  Furthermore, when the word string detection unit 115 detects the word string shown in FIG. 11, the extraction unit 116 determines that the word “today”, the word “to”, and the word “ The current date from “Tomorrow” and the date one day after the current date are extracted as time information, and the word “soccer” is used as a keyword from the word “s” and the word “soccer” of unknown meaning according to rule 5. Extract.

  In this way, the analysis processing unit 93 detects a word string from the article text supplied from the acquisition unit 112, and further extracts time information and keywords for specifying a program from the word string.

  In this way, instead of a sentence in a predetermined format, the time information and the text used by the user and the article body created without being aware of the order of the words, that is, the sentence of the natural syntax input by the user, By extracting a keyword, it is possible to easily search for a program that the user wants to record using the extracted time information and the keyword and reserve a recording.

  Therefore, the user does not need a dedicated device to make a remote recording reservation for a desired program, and does not input a program broadcast time, program name, etc. in a predetermined syntax. By simply inputting and posting an article containing the entered text on the blog, you can easily schedule remote recording of the program.

  In the above description, the recording device 63 has been described as acquiring an article posted to the user's own blog that owns the recording device 63 and scheduling recording of the program, but not the user's own blog, You may make it reserve the recording of a program using a blog of another person.

  When the recording device 63 acquires information necessary for program recording reservation using the user's own blog, the recording device 63 is provided by the server 62 using the Web public API as shown in FIG. 12A. You can post articles to your blog, get blog articles, get blog information, and get RSS feeds.

  On the other hand, when the recording device 63 uses a blog of another person different from the user to acquire information necessary for program recording reservation, the recording device 63 acquires an RSS feed as shown in FIG. 12B. It is possible to do this, but since user authentication is required to acquire detailed information about blogs and post articles, posting articles using the Web public API, acquiring blog articles, and acquiring blog information Can not do.

  Therefore, when reserving recording of a program using another user's blog, the recording device 63 performs reserving recording of the program using the outline of the article included in the RSS feed. In such a case, the recording device 63 executes the recording reservation process described with reference to FIG. 5 and reserves the recording of the program. In the article acquisition process in step S11, the recording device 63 uses the RSS feed instead of the article body. Get a summary of the included articles.

  Hereinafter, with reference to the flowchart of FIG. 13, an article acquisition process in the case of reserving recording of a program using another user's blog will be described.

  In step S <b> 101, the acquisition unit 112 acquires setting information from the setting information recording unit 111. Here, the URL for acquiring the RSS feed acquired as setting information is the URL for acquiring the RSS feed of another user's blog used for recording recording of the program, and this URL is set by the user in advance. Is done.

  In step S <b> 102, the acquisition unit 112 accesses the position indicated by the URL of the RSS feed as the setting information via the communication unit 91 and acquires the RSS feed from the server 62. For example, the acquisition unit 112 transmits a transmission request for requesting transmission of the RSS feed recorded at the position indicated by the URL of the RSS feed to the server 62 via the communication unit 91, and the server 62 includes the recording device 63. The transmission request from is received.

  Then, the server 62 transmits the RSS feed requested by the transmission request to the recording device 63 via the communication network 64. The communication unit 91 of the recording device 63 receives the RSS feed from the server 62 and supplies it to the acquisition unit 112.

  In step S103, the determination unit 121 of the acquisition unit 112 determines whether the blog has been updated based on the acquired RSS feed. If it is determined in step S103 that the blog has not been updated, the process returns to step S102, and the above-described process is repeated.

  On the other hand, when it is determined in step S103 that the blog has been updated, the process proceeds to step S104, and the acquisition unit 112 acquires the updated article summary from the RSS feed supplied from the communication unit 91. To do. That is, the summary tag part of the RSS feed includes the content of the article posted on the blog, for example, the entire article body, the first few hundred characters of the article body, etc. as the article summary. Get the summary of this article as an updated article body.

  Then, the acquisition unit 112 supplies the acquired article summary to the word string detection unit 115, and the process proceeds to step S12 in FIG. Thereafter, an analysis process is performed on the acquired article outline, and time information and keywords are extracted from the article outline to make a recording reservation for the program.

  In this way, the recording device 63 acquires the RSS feed from the server 62 and determines whether or not the blog has been updated. When the blog is updated, the recording device 63 acquires the article summary from the RSS feed.

  As described above, the RSS feed is acquired from the server 62 to determine whether or not the blog has been updated, and when the blog is updated, the outline of the article is acquired from the RSS feed. Even when is used, it is possible to easily search for a program and reserve recording of the program.

  Even when the recording device 63 reserves recording of a program using the user's own blog, the outline of the article included in the RSS feed may be used. In some cases, only the first few hundred characters of the article body are included, so even if a user posts an article to make a remote recording reservation, the article summary does not include time information and keywords There is a risk that. Therefore, when a user's blog is used for remote recording reservation, it is desirable to make a recording reservation by using the article text, not the outline of the article.

  In addition to blog articles and RSS feeds, the recording device 63 acquires articles on web pages generated using CMS (Contents Management System) and extracts time information and keywords from the acquired articles. You may make it do.

  Furthermore, in the above description, an example of a program broadcast on television as the content recorded in the recording device 63 has been described. However, in addition to this, a moving image or cable distributed from another device via the communication network 64 is used. Content such as a program distributed from another device via the recording device 63 may be recorded in the recording device 63.

  The series of processes described above can be executed by hardware or can 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 recording medium in a general-purpose personal computer or the like.

  FIG. 14 is a block diagram showing an example of the configuration of a personal computer that executes the above-described series of processing by a program. A CPU (Central Processing Unit) 311 of the personal computer 301 executes various processes according to a program recorded in a ROM (Read Only Memory) 312 or a recording unit 318. A RAM (Random Access Memory) 313 appropriately stores programs executed by the CPU 311 and data. The CPU 311, ROM 312, and RAM 313 are connected to each other via a bus 314.

  An input / output interface 315 is also connected to the CPU 311 via the bus 314. The input / output interface 315 is connected to an input unit 316 including a keyboard, a mouse, and a microphone, and an output unit 317 including a display and a speaker.
