Description

  The present invention relates to an information processing apparatus capable of creating a playlist that reflects user preferences based on a web browsing history.

  In recent years, TV program information such as EPG (Electronic Program Guide) has been distributed, and the user can select a TV program by specifying not only the broadcast time and G code but also the program name and the contents representing the program. It is. However, as the number of channels has increased, it is difficult for a user to search for a program that suits his / her taste from a huge amount of programs. Conventionally, there is a keyword search as a search method used, but skill and experience are necessary to perform an accurate search, and it cannot be said that everyone can use it. Therefore, a technique for automatically extracting a user's preference regarding a program using a user's behavior is disclosed.

  Patent Document 1 proposes a content search device that searches for video content that matches a user's preference using a keyword extracted from a bookmark (favorite) title of a Web browser. However, the preference data obtained from the keyword extracted from the bookmark title is only data for each bookmarked page, and preference data considering the browsing order in Web browsing cannot be obtained. Therefore, when considered as an information source for collecting user preference data for viewing content, it cannot be said that the title of a bookmark has a sufficient amount of information.

In Patent Document 2, user preference data is accumulated from an access history to the Internet or the like (search key and connection destination address or homepage category), and a TV program that matches the user preference is searched using the data. An information processing apparatus has been proposed. However, a specific method for determining the user's preference data from the access history and for narrowing down TV programs to be automatically received using the preference data has not been clarified.
Japanese Patent Laid-Open No. 2001-344251 (page 8, FIGS. 5 and 11) JP 2002-366570 A (pages 10-11, 14-20)

  In the future, storage-type broadcasting will progress and the time and space restrictions for TV viewing will be removed, and one program will be divided into a plurality of tagged contents, and the user can easily select them. Further, it is conceivable that a program having a shorter time than the current one is provided with the target of viewing the program in a limited time in a mobile environment or the like. In a situation where a wider variety of content can be viewed in such a limited time, the frequency of content selection by the user dramatically increases. At this time, it is necessary to manage the viewing order of each content during the total content viewing time, as well as selecting individual content. In addition, user convenience is improved by creating a playlist that takes into account viewing conditions such as viewing time and the capacity of a storage medium for storing content.

  Here, when a playlist is created taking into account only preference data for individual content, content of the same genre is biased to the top of the viewing order, and as a result, a playlist that detracts from the user's interest is created. . Therefore, in order for the user to obtain satisfaction, it is necessary to select each content in consideration of the content viewing order and create a playlist. To be frank, in general news programs on TV and radio broadcasts, programs are organized not to keep viewers bored, such as putting entertainment information and sports information in the meantime, rather than continuing with high social topics. Yes. However, it is a great effort and labor for a general user to do this every day by the user himself / herself.

  The present invention was created in view of such circumstances, and an object of the present invention is to provide an information processing apparatus capable of creating a playlist in a content viewing order that reflects user preferences without biasing a specific genre to the top. And

An information processing apparatus according to the present invention includes:
Web browsing history acquisition means for acquiring Web browsing history from outside;

  According to the above configuration, by registering the content in the playlist in the content viewing order that reflects the user's preference extracted from the Web browsing history, the specific order of the viewing order that reflects the user's preference is not biased to the top. A playlist can be created.

  In the above, the Web browsing history acquisition unit may be a Web browser that acquires the Web browsing history from the Internet, or the Web browsing history generated by another device is received and the storage unit It may be a Web browsing history receiving unit that transfers to the network.

  Further, in the above, there is an aspect in which the control unit creates the playlist taking into account viewing conditions that reflect a user's viewing environment. Here, the viewing conditions are, for example, conditions specified by the user such as the total playback time of the playlist and the playback start / end time of playback of the playlist, the capacity of the storage medium for storing the content registered in the playlist, etc. It is a condition limited by.

  In addition, in the above, there is an aspect in which a playlist transmission unit that reads the playlist from the storage unit and transmits the playlist to another device is provided. The created playlist can be expanded to other devices.

  Further, in the above, there is an aspect in which the apparatus further includes a playlist receiving unit that receives the playlist from another device and transfers the playlist to the storage unit. A playlist created in another device can be used in the information processing apparatus.

  Further, in the above, there is an aspect in which the control unit reads the playlist from the storage unit and specifies an ID (identifier), a start time, and an end time of the reproduction content with respect to the storage unit. And the said control means has the aspect of reading the said reproduction | regeneration content specified based on the said play list with respect to the said memory | storage means.

  According to the present invention, by registering content in the playlist in the content viewing order that reflects the user's preference extracted from the Web browsing history, the play in the viewing order that reflects the user's preference without biasing the specific genre to the top. You can create a list.

  Embodiments of an information processing apparatus according to the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the information processing apparatus A1 in the first embodiment, and FIG. 2 shows a user's Web browsing history 31 obtained through the Web browser 11. FIG. The web browsing history 31 includes a URL (Uniform Resource Locator), whether bookmarks are registered, and the number of accesses.

  FIG. 3 extracts the keyword α and the preference coefficient δ of each page in the Web browsing history 31, registers only pages whose preference coefficient δ exceeds the threshold, and then integrates adjacent pages having the same keyword. The page information table 32 is shown. β is the related coefficient of the keyword, and γ is the continuity of the keyword. Specifically, page 1 and page 2 are adjacent to each other via the same keyword “USA”. Page 2 and page 3 are adjacent to each other via the same keyword “sports”. Page 3 and page 4 are adjacent to each other via the same keyword “Europe”. Page 4 and page 5 are adjacent to each other via the same keyword “travel”. Page 5 and page 6 are adjacent to each other via the same keyword “news”. Page 6 and page 7 are adjacent to each other via the same keywords “news” and “economy”.

  FIG. 4 shows a viewing order information table 33 created by extracting the keyword α and the preference coefficient δ from the page information table 32 and rearranging the keyword α according to the priority of the keyword on each page.

  FIG. 5 shows a playlist 40 created using the viewing order information table 33, viewing conditions, and content metadata. Here, the viewing conditions are, for example, conditions specified by the user, such as the total playback time of the playlist 40 and the playback start / end time of playback of the playlist 40, and the capacity of the semiconductor memory that stores the content registered in the playlist 40 It is a condition limited by the equipment.

  In the embodiment of the present invention, a playlist 40 composed of movie contents all having a bit rate of 1 Mbps and movie contents registered in the playlist 40 are stored in a semiconductor memory having a capacity of 512 megabytes. Assume that the total playback time is limited to 60 minutes.

  The information processing apparatus A1 is connected to the Internet 21 and provides a user with means for performing web browsing (browsing home pages on the Internet). Further, the information processing apparatus A1 can receive a digital TV broadcast program, and includes a Web browser 11, a tuner 12, a decoder 13, a content receiving unit 14, a content metadata receiving unit 15, a storage as a Web browsing history acquisition unit. Unit 16, operation unit 17, control unit 18, and playlist transmission unit 19. Reference numeral 22 denotes an external display device.

  Here, the digital TV broadcast program assumed in the embodiment of the present invention is content metadata in which program information and information of each scene constituting the program are described in a general description language together with encoded video data and audio data. Are multiplexed. As the general-purpose description language, for example, a general-purpose description language such as XML (eXtensible Markup Language) can be used. The tags constituting the content metadata are data relating to the program (program name, broadcast station name, channel), data representing the content of the scene (keyword, summary), a counter representing the start time / end time of the scene, and the like.

  In the embodiment of the present invention, the information processing apparatus A1 is installed at home as a home AV server, and the storage unit 16 of the information processing apparatus A1 is preliminarily connected via the tuner 12, the decoder 13, and the content receiving unit 14. A sufficient amount of programs have been recorded. Further, content metadata corresponding to all recorded programs is also recorded via the tuner 12, the decoder 13, and the content metadata receiving unit 15. For recording digital TV broadcast programs and receiving content metadata, for example, reservation recording by EPG may be applied. Then, in order to view a plurality of programs recorded at the destination and a scene of the recorded program divided by the metadata scene information, an appropriate playlist 40 is created and stored in the storage unit 16 by the information processing apparatus A1. In this example, the playlist 40 and programs and scenes registered in the playlist 40 are stored in the semiconductor memory through the playlist transmission unit 19.

  The Web browser 11 is connected to the Internet 21 via a communication interface, provides Web browsing means to the user, and writes a Web browsing history 31 in the storage unit 16.

  The tuner 12 is connected to the decoder 13 via a signal line, receives a broadcast digital TV broadcast program, and obtains encoded video data and audio data.

  The decoder 13 decodes the encoded video data and audio data obtained by the tuner 12 and content metadata including information on the program and each scene constituting the program.

  The content receiving unit 14 receives the program extracted from the decoder 13 and writes it in the storage unit 16 according to an instruction from the control unit 18.

  The content metadata receiving unit 15 receives the content metadata extracted from the decoder 13 and writes it in the storage unit 16 according to an instruction from the control unit 18.

  The storage unit 16 stores and reads out the Web browsing history 31, the page information table 32, the viewing order information table 33, the playlist 40, the content metadata, and the program.

  The control unit 18 creates a page information table 32 indicating user preference information on each page of the web browse history 31 from the web browse history 31. Also, a viewing order information table 33 that defines the content viewing order using the page information table 32 is created. In addition, the control unit 18 creates a playlist 40 using the viewing order information table 33, content metadata, and viewing conditions, writes the playlist 40 in the storage unit 16, and also sends the playlist 40 to the playlist transmission unit 19 Is written to the semiconductor memory.

  The operation unit 17 provides the user with operation means necessary for Web browsing and playlist creation such as a mouse and a keyboard.

  The playlist transmission unit 19 is a semiconductor memory reader, and reads the playlist 40 stored in the storage unit 16 according to an instruction from the control unit 18 and writes it to the semiconductor memory.

  Next, the operation of the information processing apparatus A1 in the present embodiment will be described with reference to a flowchart.

  FIG. 6 shows a keyword α for each page in the web browsing history 31 and a preference coefficient δ representing the user's preference for the page. After registering only pages whose preference coefficient δ exceeds a threshold, It is a flowchart which shows a series of control operation | movement until integrated page is integrated and the page information table 32 is produced. FIG. 7 is a flowchart for extracting the keyword α and the preference coefficient δ in the page information table 32 and rearranging the keyword α according to the priority of the keyword in each page until the viewing order information table 33 is created. FIG. 8 is a flowchart until the playlist 40 is created using the viewing order information table 33, viewing conditions, and content metadata.

  First, using FIG. 6, the keyword α and the preference coefficient δ of each page in the Web browsing history 31 are extracted, and only pages whose preference coefficient δ exceeds the threshold are registered, and then adjacent pages having the same keyword are integrated. A series of control operations until the page information table 32 is created will be described.

  In this embodiment, the user performs Web browsing in advance using the Web browser 11 provided in the information processing apparatus A1, and the playlist is stored by the Web browser 11 storing the history in the storage unit 16. The web browsing history 31 can be obtained before the creation work. Since the web browsing history 31 is updated every time the user performs web browsing, the latest preference of the user is automatically reflected in the playlist 40 by using the latest web browsing history 31 when creating the playlist. .

The control unit 18 calculates a preference coefficient δ representing the magnitude of the user's preference for each page of the web browsing history 31 (step S1). The preference coefficient δ is, for example,
[Page stay time] x k ₁ + [Bookmark flag] x k ₂ + [Number of accesses] x k ₃ …
It may be defined as follows. Then, the control unit 18 enters the registration work of the viewing order information table 33 for each page of the history (step S2). Compare the preset threshold value with the preference coefficient δ of the registered work target page, position the page with the preference coefficient δ larger than the threshold value as the page where the user's preference appears, and measure the user's viewing flow (Step S3). If the threshold value is set to be lower here, a finer flow of viewing by the user can be reflected in the playlist 40. On the other hand, if the threshold is low, there may be too many pages registered in the page information table 32 and the original user's preferences may not be collected. If it is intended to avoid this, the threshold can be set higher. is there.

From a page having a preference coefficient δ larger than the threshold value, a keyword α highly relevant to the page content is extracted (step S4). The keyword α is selected in order from a word / phrase having a high keyword-related coefficient β indicating the degree of relevance between the page content and the word / phrase. Here, the keyword-related coefficient β is for a certain phrase, for example,
[Number of words / phrases that exist in the page] × k ₁₁ + [Number of words / phrases that exist in the anchor text (link character string) of the link from another page] × k ₁₂ + [Web Presence flag of the word / phrase in the search key history of the user stored in the browser] × k ₁₃ + [number of words / phrases present in bookmark title of Web browser] × k ₁₄ ...
It may be defined as follows. Then, the preference coefficient δ possessed by the page, the keyword α highly relevant to the page contents, and the related coefficient β of each keyword α are registered in the page information table 32 (step S5). In the present embodiment, the number of keywords α registered in the page information table 32 is three per page, but is not limited to this. The registration work is repeated for all pages in the web browsing history 31 (step S7), and after the registration work for all pages is completed (step S6), adjacent pages having the same keyword are integrated (step S8). . At this time, a value obtained by averaging the preference coefficients δ of a plurality of pages of the integration source is set as the preference coefficient δ of the integrated pages.

  With the above operation, the control unit 18 creates the page information table 32 and stores the page information table 32 in the storage unit 16.

  Next, a series of control operations until the priority of each keyword α in the page information table 32 is determined and the viewing order information table 33 is created will be described with reference to FIG.

  The control unit 18 calculates the continuity γ of all keywords registered in the page information table 32. Here, the keyword continuity γ is a value obtained by counting how many times the keyword α registered on the page has been registered on the page. The continuity γ will be described using the keyword “news” in the page information table 32 as an example. First, the keyword “news” is registered in page 1, but is not registered in page 2 as any keyword from keyword 1 to keyword 3. Accordingly, the keyword “news” can be regarded as being interrupted on page 1, and “1” is given to the continuity γ of the keyword “news” registered on page 1. Also, since the continuity γ of the keyword is reset to “0” at the moment of interruption, the continuity γ is counted up again from “1” even if the same keyword is registered in the subsequent pages. . Next, since the keyword “news” is registered again on page 5, page 6, and page 7, the continuity γ of the keyword “news” on page 5, page 6, and page 7 is set to “1”, “2”, Count up like “3”. Then, the page information table 32 ends at page 7, but in this case, it is considered that the continuity γ is interrupted at page 7 for all keywords α. When the keyword continuity γ is counted up to “2” or more, the keyword α of each page is given the continuity γ at the moment when the continuity γ is interrupted. Therefore, the continuity γ of the keyword “news” registered in page 5, page 6, and page 7 in the page information table 32 is all given “3” as the value of continuity γ in page 7. As described above, in the page information table 32 according to the present embodiment, the continuity γ of the keyword “news” registered in page 1 is “1”, and the keyword “news” registered in page 5, page 6, and page 7 is the same. The continuity γ is calculated as “3”.

  First, keyword 1 of page 1 is set as a survey target keyword, and a survey of continuity γ is started (step S11). Next, it is confirmed that the keyword to be investigated is registered in any one of keyword 1, keyword 2, and keyword 3 on the next page (step S12). If it is also registered in the next page, the continuity γ of the search target keyword is increased by “1” (step S13). On the other hand, if it is not registered in the next page, it is determined that the continuity γ of the search target keyword is interrupted, and the continuity γ of the search target keyword is determined (step S14).

  The continuity survey for keyword 1 on page 1 has been completed, but since keyword 2 and keyword 3 are still registered on page 1, next, keyword 2 on page 1 is set as the keyword to be surveyed (step S16). ), The continuity survey is performed in the same procedure as for keyword 1. After the keyword 2 survey is completed, the keyword 3 on the page 1 is also surveyed. Since the search for all the keywords α registered in page 1 is completed by the above operation, the search object is moved to the next page 2 (step S18), and the continuity γ of keyword 1 on page 2 is checked. Thereafter, similarly, continuity investigation is performed on all keywords α registered in all pages of the page information table 32, and the continuity γ of each keyword α is determined.

When the continuity γ of all keywords is determined, the ranking of the keywords α on each page is performed (step S19). For ranking keywords α, for each keyword α,
Keyword priority = [Keyword continuity γ] × k ₂₁ + [Keyword related coefficient β] × k ₂₂
And the keyword α having a high priority is set at the top. In this embodiment, assuming that k ₂₁ = 1 and k ₂₂ = 0, the keywords α are ranked on each page using only the keyword continuity γ as a scale. Of course, the values of k ₂₁ and k ₂₂ are used. Is not limited to this. Finally, the control unit 18 extracts the keyword α and the preference coefficient δ from the page information table 32 and registers them in the viewing order information table 33 to create the viewing order information table 33 (step S20). Then, the control unit 18 writes the viewing order information table 33 in the storage unit 16 and completes the viewing order information table 33.

  Next, a series of control procedures until the playlist 40 is created using the viewing order information table 33, viewing conditions, and content metadata will be described with reference to FIG.

  First, the control unit 18 reads the viewing order information table 33 from the storage unit 16, compares the preference coefficient δ in each viewing frame of the viewing order information table 33, and selects the viewing frame having the largest preference coefficient δ, that is, the viewing frame 2 as the content. A registration target frame is set (step S31). Next, the control unit 18 obtains the viewing time T allocated to the viewing frame 2 using the viewing condition 34 (step S32). Here, the viewing time T allocated to the viewing frame 2 is obtained by multiplying the value 0.23 obtained by normalizing the preference coefficient δ of the viewing frame 2 by the sum of the preference coefficients δ of all viewing frames and the total playback time 60 minutes of the playlist 40. This is the combined value and is calculated as 14 minutes.

  A calculation example here is as follows.

7 + 10 + 6 + 4 + 3 + 8 + 5 = 43
10 ÷ 43 ≒ 0.23
0.23 × 60 ≒ 14
When the viewing time T is obtained, the control unit 18 starts searching for content that matches the user's preference in the viewing frame 2 that is the content registration target frame from the content metadata 35. The search is performed using a keyword in the viewing frame 2, but the control unit 18 first sets all the keywords α registered in the viewing frame 2 as search keywords (step S33) and connects them with AND. A keyword search is performed on the content metadata 35 (step S34). Next, the control unit 18 determines whether or not one or more search results exist (step S35). If one or more search results exist, the playback time of the content listed at the top of the search results and the previously obtained viewing time are determined. T is compared (step S36). If the highest content playback time of the search result is less than or equal to the viewing time T, the highest content of the search result is registered in the viewing frame 2 of the playlist 40 (step S37), and the playback time of the registered content is viewed. By subtracting from the time T, the remaining reproduction time that can be stored in the viewing frame 2 is updated (step S38). Then, the registered contents are removed from the search result, and it is confirmed in the same procedure whether the second and subsequent contents in the search result can be registered in the viewing frame 2. If the playback time of the top content of the search result is longer than the viewing time T in step S36, the top content of the search result cannot be registered in the viewing frame 2 of the playlist 40, so steps S37 and S38 are skipped. Thereafter, as in the case where the highest content is registered, the confirmation work as to whether or not the second and subsequent content in the search result can be registered in the viewing frame 2 is entered.

  If the search result is 0 because the search result is removed in the process of confirming the registration of the content of the search result, or if the search result is 0 from the beginning, the lowest keyword is selected from the search keywords. By removing the search keyword, the search keyword is changed (step S40). That is, the first search keyword in the viewing frame 2 was “America”, “Sports”, and “Baseball”, but after passing through step S40, the keyword “baseball” in rank 3 was removed and the search keyword was changed to “America”. ”And“ Sports ”. If the search keyword is changed, the search keywords are connected again with AND, and the content metadata 35 is searched. The subsequent content registration confirmation procedure is the same as before the search keyword change.

  If the content is registered in the viewing frame 2 by the above procedure and the number of search keywords becomes zero (step S41), the viewing frame having the highest preference coefficient δ next to the viewing frame 2 in the viewing order information table 33 is displayed. Search to obtain the viewing frame 6. Then, the viewing frame targeted for playlist registration is changed to the viewing frame 6 (step S43). The subsequent content registration procedure is the same as the procedure in the viewing frame 2, and the control unit 18 finishes the playlist creation when the content registration work is completed for all viewing frames in the playlist 40 (step S42), and stored. By writing the playlist 40 in the part 16, the playlist 40 is completed. Looking at the playlist 40 in FIG. 5, the playlist is in the order of viewing that reflects the user's preference without biasing the specific genre to the top.

  Also, the playlist transmission unit 19 receives an instruction from the control unit 18, reads the completed playlist 40 from the storage unit 16, and writes it to a semiconductor memory that is a storage medium.

  As a result, the user can obtain a playlist 40 for simply viewing only the content that suits his / her preference from the recorded TV programs and TV program scenes. It can also be taken out to equipment. Further, since the playlist 40 is created in consideration of the flow between contents, the user can obtain a playlist 40 with a balanced organization in which only specific contents are not biased. Even when any viewing condition occurs, the user can automatically obtain the playlist 40 for optimal content viewing without special consideration.

  In the above-described embodiment, a description has been given of a mode in which a semiconductor memory reader is used for the playlist transmission unit 19, but the present invention is not limited to this. For example, if an infrared device, a wireless LAN communication device (802.11b / g / a), a Bluetooth communication device, or the like is used, media 40 is not required, and the playlist 40 can be transmitted more easily.

  In the above embodiment, the decoder 13 decodes the digital TV broadcast program received by the tuner 12, and the content metadata receiving unit 15 uses the metadata multiplexed in the digital TV broadcast program. However, the present invention is not limited to this. For example, a communication form via the Internet 21 can be used. It is also possible to use a bridge medium such as a semiconductor memory. Similarly, the content receiving unit 14 can also receive content using a communication form via the Internet 21 or bridge media.

  In the above embodiment, the control unit 18 creates the playlist 40 and stores it in the semiconductor medium through the playlist transmission unit 19. However, the control unit 18 stores the playlist 40 stored in the storage unit 16. May be adopted in which the content registered in the playlist 40 is read out from the recording means. Thereby, the user can appreciate the content registered in the created playlist 40 with the information processing apparatus A1.

(Embodiment 2)
In order to create the playlist 40 using the Web browsing history 31 created by another device, it is effective to have an information processing apparatus A2 having a functional configuration as shown in FIG. Each configuration will be described in detail.

  A web browsing history receiving unit 20 as a web browsing history acquisition unit is connected to the storage unit 16 via a signal line, receives a web browsing history 31 generated by another device, and receives instructions from the control unit 18. The web browsing history 31 is written in the storage unit 16. Since other configurations are the same as those in FIG. 1 in the case of the first embodiment, the same reference numerals are given to the same portions, and descriptions thereof are omitted.

  In this way, the playlist 40 can be created using the web browsing history 31 created on a home or office PC (personal computer), and a wider variety of playlists 40 can be created. In addition, some mobile phones having a function of connecting to the Web also have a function of storing the Web browsing history 31, which can be used to create a playlist 40 having a pattern different from that of the PC. The possibility of creating a product that matches your taste increases.

  The information processing apparatus according to the present invention registers the content in the playlist in the content viewing order that reflects the user's preference extracted from the Web browsing history, and thus the viewing order that reflects the user's preference without biasing the specific genre to the top. This is useful for applications such as stationary media servers and portable media viewers.
