JP4823961B2 - Content list management method for information appliances - Google Patents

Description

  The present invention relates to a content list management method for a display device of an information home appliance.

  Conventionally, information appliances with a display (including AV planes such as digital television (DTV) and set top box (STB)), white planes such as air conditioners and refrigerators, and PC planes such as PCs, printers, and digital cameras) Terminals are mutually connected, and a home network (so-called home network) is constructed as an internal network. In this internal network (home network; home network), for example, a protocol such as Digital Living Network Alliance (Digital Living Network Alliance); DLNA, UPnP, ECHONET, and the like has been proposed.

  Furthermore, information home appliances as a terminal (internal terminal; Home Device (HD)) on this internal network (home network; home network) are, for example, Home Access (HA); Gateway device, Home Bridge (HB); Hub And routers, Home Client (HC); connected to external networks (including IP networks) via controllers of information appliances, etc., unidirectional content reception mainly for broadcasting services, and communication by IP communication Provides services (two-way communication mainly using the Internet). In addition, various information appliances are remotely operated and monitored via an internal network, and various services such as home security are also provided.

  By the way, when these information home appliances acquire content on the external network, after the content is once stored in the internal server on the internal network, the content required by the information home appliance is transferred to the internal server via the internal network. Download from.

  For example, the gateway device as the internal server receives data on the content acquisition address, content identifier, and content storage capacity from the information home appliance via the internal network, and the content from the server corresponding to the content acquisition address via the IP network Here, when the content identifier of the content matches the content identifier of the information appliance, the content is sent to the information appliance according to the content storage capacity (for example, patent Reference 1).

  In addition, when information is transmitted from a wide area network (WAN) to an information terminal connected to a local area network (LAN), the gateway device as an internal server temporarily stores the reception information received from the WAN, and the information related to the reception information is stored. There is one in which broadcast information is generated and broadcast on the LAN. Here, the information terminal determines whether or not the reception information received by the gateway device is necessary based on the broadcast communication information, and if necessary, an acquisition request is made from the information terminal to the gateway device, Received information is sent from the gateway device to the information terminal via the LAN (see Patent Document 2).

Due to recent advances in storage medium technology, the storage capacity of the internal server has become extremely large. For example, a 200 GB HDD can record more than 500 hours. For this reason, since a huge amount of content headings are displayed on the display unit of the information appliance, it is difficult for the user to determine the content to be viewed. On the other hand, for example, a user extracts specific content using a search term such as the name of a favorite actor, and views the content.

  Next, an example of functional configurations of the external server 10 and the internal server 100 illustrated in FIG. 1 will be described with reference to FIG. The external server 10 includes a two-dimensional barcode generation unit 112 for generating a two-dimensional barcode representing a predetermined URL, and an image data generation unit 111 for generating image data. The internal server 100 includes a content request data receiving unit 201, a content request data transmitting unit 202, a user ID / password data receiving unit 203, a user ID / password data transmitting unit 204, a content data / folder association data receiving unit 205, a content tree structure A data conversion unit 206, a content tree structure data / content data transmission unit 207, and a protocol conversion unit 208 including a content tree structure data conversion unit. The protocol conversion unit 208 is connected to the external server 10 as a terminal. The protocol conversion with the information home appliance 70 with display is performed.

  The user ID / password data receiving unit 203 is connected to an information terminal device such as a PC, and receives user ID / password data as user identification data.

  FIG. 4 shows a content transmission processing procedure according to an example of the preferred embodiment of the present invention. First, the content request data receiving unit 201 of the internal server 100 receives data for requesting content from the information home appliance with display 70 on the internal network (step S101). Here, the user ID / password data receiving unit 203 of the internal server 100 may receive user ID / password data as user identification data in advance from a PC or the like. In this case, the received user ID / password data is set in the internal server 100 thereafter.

  Next, the internal server 100 converts the received request data of the content from the protocol of the internal network into the protocol of the external network, and transmits it to the external server 10 via the external network 50 (FIG. 1) (step). S102). At this time, if a user ID / password is set in the internal server 100, the user ID / password data transmission unit 204 further transmits the user ID / password data to the external server 10 via the external network 50. .

  The external server 10 transmits data indicating the requested content and the association of the content by the folder to the internal server 100 via the external network 50. Further, when the external server 10 further receives the user ID / password data, the external server 10 determines whether or not the user ID / password data is registered. If the user ID / password data is registered, the external server 10 specifies the user ID / password data. Data indicating the customized content and link structure is transmitted to the user.

  Here, the external server 10 generates image data for displaying the content data to be transmitted in a predetermined size as necessary, and further, if necessary, a two-dimensional barcode (a QR code) representing a predetermined URL. Is generated and inserted into the image data (step S103). Thereafter, the external server 10 transmits the content data and image data to the internal server 100 via the external network 50.

  Next, the internal server 100 receives data indicating the content and the association of the content by the folder from the external server 10 by the content data / folder association data receiving unit 205 (step S104).

  Next, the content tree structure data conversion unit 206 of the internal server 100 converts the content tree structure data into content tree structure data based on the data indicating the link structure (step S105).

  Next, after the internal server 100 associates the content data with each node of the content tree structure (step S106), the content tree structure data / content data transmission unit 207 includes a display as a terminal on the internal network. The content tree structure data and the content data are transmitted to the information home appliance 70 (step S107). When the content data includes image data generated by the external server 10 described above, the internal server 100 transmits the image data as content data.

  Then, the internal server 100 determines whether or not there is further content request data (step S108). If there is content request data, the process returns to step S101 to continue the process, and if there is no content request data, the process ends. .

  By the way, when the user ID / password is set in the internal server 100, user identification data setting processing according to an example of the preferred embodiment of the present invention shown in FIG. 5 is performed. First, the user ID / password data receiving unit 203 receives data for setting a user ID / password as user identification data from a PC or the like connected to the internal server 100 (step S201).

  Next, the internal server 100 stores and saves this user ID password in a memory (not shown) (step S202). Note that a plurality of user IDs / passwords may be set in the internal server 100. In that case, when receiving data requesting content from the information home appliance with display 70 as a terminal thereafter, the plurality of user IDs / passwords are set. Data for designating one of the user ID and password may be further received.

  Subsequently, an example of the above-described content transmission method will be specifically described. First, referring to FIG. 6, FIG. 6 is a diagram illustrating a general definition of an internal network according to an example of a preferred embodiment of the present invention. Here, the internal server 100 (proxy) is connected to an external network 50. It is an interface for connecting information appliances etc. existing on the internal network, and has, for example, a connection function between the outside and home network, a broadcast service reception function, a home network management function, a middleware conversion function, etc. Yes. On the other hand, a unique protocol domain is defined in the home network. Here, there are a PC plane, an AV plane, a white object plane, and a telephone / FAX system as shown. The internal network may be realized by a power network or a wireless network such as Zigbee.

  Referring to FIG. 7, an external server (Web server) 10 according to an example of a preferred embodiment of the present invention includes a user DB and a content DB. The content data is converted into, for example, JPEG, MPEG, or MP3 and transmitted to the internal server 100. At this time, the external server 10 may transmit the folder specification XML to the internal server 100 in order for the internal server 100 to expand the content data in a folder.

  In this case, the internal server 100 receives the XML data generated by the Web server with reference to the content DB, and converts the XML data into content tree structure data based on the XML data.

  FIG. 8 is a diagram showing a pattern for creating a folder directly from the DB. For example, a news DB, which is one of the content DBs, includes columns for ID, headline, text, photo, category, and UP date. When creating a folder, for example, XML is generated from the DB, JPEG data is further generated, and stored in the folder. Similarly, the moving image DB and the weather DB are also stored in folders.

  In the illustrated example, a news folder, a movie folder, and a weather folder are generated at the top (top folder). When the news holder is opened, domestic, overseas, and economic folders are further generated. When the domestic folder is opened, various JPEG files can be referred to. In the terminal, that is, the information home appliance with display 70, when the country is selected from the news and the “AAA” JPEG file is further selected, the corresponding file is opened and displayed on the screen.

  By doing so, the terminal, that is, the information home appliance 70 with a display, can display the image of the Web page and check the image of the page that is displayed on the Web browser. You can also display lower-level folders.

  When the HTML document includes an anchor tag for another HTML document, a two-dimensional barcode (or QR code) indicating the URL indicated by the anchor tag may be generated and inserted into the image data for display. .

  FIG. 9 is a schematic diagram illustrating an example of the configuration of the internal server 100. As shown in FIG. 9, the internal server 100 includes a control unit 100a and a received content DB 100b. The received content DB 100b is a storage device for storing content that has been converted into content tree structure data and stored as described above.

  FIG. 10 is a diagram illustrating an example of a table in the received content DB 100b. The received content DB 100b stores an ID table shown in FIG. 10A and a content table shown in FIG. In the relationship with the tree structure described above, the JPEG file at the end (see FIG. 8) corresponds to the received content.

  List information and association information are stored in the ID table. The list information is information indicating a content heading. The list information includes, for example, a title, access, acquisition date / time, G code, and the like. The title is the title of the content, for example, “Hokkaido Solo Travel”. The access is a TV channel or URL for acquiring content. The acquisition date and time is the date and time when the content is received. The G code is recorded when it exists. The association information is a numerical value / English character string unique to each content for associating the ID table list information with the received content of the received content table.

  As shown in FIG. 10B, the display order is associated with the received content in the received content table. As a display order immediately after receiving the received content, a smaller number is assigned to a later received date, that is, a new received content. As will be described later, this display order is changed by the list additional information received from the external device 20.

The evaluation determination unit 43 is a configuration for determining an evaluation for a search term in the extracted content. The evaluation determination unit 43 is an example of an evaluation basic information extraction unit, an example of an association degree calculation unit, an example of an association degree calculation unit, and an example of a recommendation order determination unit. The list additional information transmission unit 44 is configured to transmit list additional information for rearranging the list information of the internal server 100.

  FIG. 16 is a schematic diagram illustrating an example of the configuration of the corresponding content extraction unit 42. As shown in FIG. 16, the corresponding content extraction unit 42 includes a search word extraction unit 42a, a search processing unit 42b, a search result generation unit 42c, a search log recording unit 42d, and a WEB page DB 42e.

  FIG. 17 is an explanatory diagram of the search word extraction unit 42a. As shown in FIG. 17, the search word extraction unit 42 a is configured to extract, for example, text data “Hokkaido solitary journey” from the identification information and use it as a search word.

  FIG. 18 is a diagram illustrating a search result of a search performed by the search processing unit 42b using the above-described search terms. As shown in FIG. 18, the address of content such as a blog including a search word is acquired as a search result.

  FIG. 19 is a diagram illustrating an evaluation method by the evaluation determination unit 43 (see FIG. 15). For example, a blog as content is as shown in FIG. In this case, as shown in FIG. 19B, the evaluation determination unit 43 is negative as a word indicating a positive evaluation (hereinafter referred to as a “positive evaluation word”) for the search term “Hokkaido solo trip”. A word indicating evaluation (hereinafter referred to as “negative evaluation word”) is specified. Words indicating a positive evaluation are defined in advance, such as “interesting”, “fun”, “worthy”, “joyful”, “feeling”, “gorgeous”, “deal”, and the like. Words indicating negative evaluation are also defined in advance, for example, “not boring”, “boring”, “valueless”, “offset”, “feeling bad”, “poor”, “expensive”, and the like. In FIG. 19B, “interesting” and “recommended” are specified as positive evaluation words, and “sorry” is specified as negative evaluation words. As shown in FIG. 19C, the evaluation determination unit 43 extracts a positive evaluation word and a negative evaluation word corresponding to the search word from the blog text. Then, the evaluation determination unit 43 subtracts the number of negative evaluation words from the number of positive evaluation words, and calculates “+1” as the evaluation value of “Hokkaido solo trip”, for example, as shown in FIG. .

  Furthermore, the evaluation determination unit 43 calculates the degree of association. The degree of association is an index indicating how much a specific search term is related to the user's preference. Specifically, the degree of association is the degree of overlap between a specific search word morpheme and a search word morpheme generated from text information among the list information of each content stored in the internal server 100 of the user. Show.

  FIG. 20 is a diagram illustrating an example of relevance calculation. Here, it is assumed that the reference search term is “Hokkaido solo trip”. As shown in FIG. 20A, the morphemes are “Hokkaido”, “One person”, and “Travel”, which are called standard morphemes. The reference morpheme and reference morpheme overlap 100%. The morpheme of “Tohoku solitary journey” overlaps with the reference morpheme by 66%, and the morpheme of “Kanazawa solitary journey” also overlaps with the reference morpheme by 66%. In this way, the degree of relevance is calculated by calculating the degree of overlap with the reference morpheme for all text information morphemes in the list of list information (see FIG. 10A) and dividing by the number of all text information. To do. In the present embodiment, it is 77% as shown in FIG.

FIG. 21 is a diagram illustrating an example of a recommendation order determination method. The evaluation determination unit 43 first calculates a recommended reference value based on the evaluation value and the degree of association. The recommended reference value is a value obtained by adding an evaluation value to a numerical value calculated by the formula shown in FIG. As shown in FIG. 21B, the recommendation order increases as the recommendation reference value increases. That is, the recommendation order increases as the evaluation value increases and the degree of relevance increases. The information indicating the recommendation order is an example of list additional information.
The above is the configuration of the content transmission system 1 of the present embodiment. Next, a main operation example of the content transmission system 1 will be described mainly using FIG.

FIG. 22 is a schematic flowchart illustrating a main operation example of the content transmission system 1.
First, the external device 20 receives list information from the internal server 100 (step S1 in FIG. 22). Subsequently, the external device 20 extracts the corresponding content (step S2). Subsequently, the external device 20 extracts evaluation basic information from the content (step S3). Subsequently, the external device 20 calculates an evaluation value (step S4).

  Subsequently, the external device 20 calculates the degree of association (step S5). Subsequently, the external device 20 calculates a recommended reference value (step S6). Subsequently, the external device 20 determines the recommendation order (step S8). Subsequently, the external device 20 transmits list additional information indicating the recommendation order (step S8). Subsequently, the internal server 100 rearranges the list information based on the list additional information (step S9). Subsequently, the internal server 100 displays the rearranged list information on the display device of the terminal 70.

By providing the configuration as described above, the external device 20 can determine the recommendation order that is the display order of the headings, and can transmit the list additional information indicating the recommendation order to the internal server 100. Since the recommendation order is based on the evaluation basic information and the relevance degree, the positive order is higher and the relevance order is higher as the relevance degree is higher, and is determined so as to suit the user's preference.
The internal server 100 can rearrange the headings indicated in the list information based on the list additional information and display the list information after the rearrangement.
For this reason, the internal server 100 can preferentially display interesting content on the display device of the information home appliance.

  ADVANTAGE OF THE INVENTION According to this invention, the content management method which can display an interesting content on the display apparatus of information household appliances preferentially can be provided.

Subsequently, a main operation example of the content transmission system 1A will be described.

  25 and 26 are schematic flowcharts for explaining a main operation example of the content transmission system 1A. First, the internal server 100A receives a request for list information from the personal computer 70E in the hotel 61 (step S20 in FIG. 25). Subsequently, the internal server 100A transmits list information to the external device 20 and requests list additional information (step S21). Steps S22 to S30 are the same as steps S1 to S9 of the first embodiment, and thus description thereof is omitted.

  Following step S30, the internal server 100A transmits the sorted list information to the personal computer 70E (step S31). Subsequently, the personal computer 70E receives the list information (step S32) and displays it on the display device (step S33). Subsequently, the personal computer 70E receives the content selected by the user from the internal server 100A (step S34).

  As described above, a user who lives in the user house 60 accesses the internal device 80 in the user house 60 via the IP network 50 in the hotel 61 at the destination, for example, and stores the list information stored in the internal server 100A. Can be received. For example, when the personal computer 70E accesses the gateway 90, the internal server 100A accesses the external device 20 via the gateway 90 and the IP network 50, requests the list additional information, and uses the received list additional information to obtain the list information. It comes to rearrange. After the list information is rearranged, the list information is transmitted to the personal computer 70E. When the user browses the list information displayed on the personal computer 70E and selects a desired content heading, the user can receive the corresponding content from the internal server 100A.
