Hereinafter, embodiments of the present invention will be described.
(First embodiment)
FIG. 1 is a block diagram showing a network system including an information processing terminal (hereinafter referred to as a terminal) according to the first embodiment of the present invention.
In the network system according to the first embodiment, a terminal 111, a television 112, and an HDD (Hard Disk Drive) recorder 113 are connected via a home network 101 which is a local network. The home network 101 is connected to the public network 102 via the router 114, and the electronic bulletin board server 121 is connected to the public network 102.

  Here, the local network refers to a network constructed by enabling data transmission / reception between terminals or the like existing within a limited range such as a home or the same building. The public network is a network constructed by interconnecting a plurality of local networks, for example, a network such as the Internet.

  The HDD recorder 113 is a storage device that stores content data. Here, it is assumed that the content data is recorded and stored on a broadcast television program. Further, it is assumed that the HDD recorder 113 stores such a television program in association with identification information for identifying the television program.

  Here, the identification information for identifying the television program may be any information that can identify the television program based on the identification information. For example, program information used in EPG (Electronic Program Guide) may be used as identification information, and a G code may be used as identification information. Alternatively, a content ID defined by the content ID forum can be used. Furthermore, if a manufacturer that provides a storage device for storing a TV program has a function for adding and storing unique identification information when recording a TV program in a storage device handled by the manufacturer, It is also possible to use identification information.

  The unit to which the identification information is given is not necessarily a program unit. For example, it may be given for each corner in the program, and the program is divided by a predetermined time unit. It may be given every time.

  The HDD recorder 113 is preferably a so-called “multi-channel all-time recording recorder”. That is, for example, multiple channels of terrestrial broadcasting (or BS broadcasting, digital broadcasting, CATV, Internet distribution content, etc.) can be recorded for a long time such as 24 hours or more, and any recorded program can be recorded at any time. It is preferable that it can be viewed.

  The electronic bulletin board server 121 is a server that provides an electronic bulletin board service that can be freely read and written by all of the participants (or members of some membership system community). The electronic bulletin board server 121 receives and stores document data or the like written by the user on the electronic bulletin board, and displays it on the electronic bulletin board so that other users can view it.

  As a method of sharing and viewing content data including image information and audio information on such an electronic bulletin board, there is a hyperlink. A hyperlink refers to a character string representing position information such as another document or image embedded in a document. In general, when a user of an electronic bulletin board clicks a hyperlink on the electronic bulletin board, the electronic bulletin board server displays content data existing at the position indicated by the hyperlink on the user's terminal so that the user can view it. . According to the prior art, the content data represented by such a hyperlink exists on the electronic bulletin board server or another WWW server on the public network, so that the content data is displayed on the user terminal. The content data is transmitted to the user's terminal via the public network.

  On the other hand, in the first embodiment of the present invention, what is transmitted from the electronic bulletin board server 121 to the user terminal 111 via the public network 102 is not the content data itself but identification information of the content data. Since the content data viewed by the user is stored in the HDD recorder 113 on the home network 101 to which the terminal 111 belongs, the content data itself is not transmitted / received via the public network 102.

  The hyperlink on the electronic bulletin board for realizing such an embodiment may be expressed as, for example, “anydevice @ localnetwork / TVProgramTitle / 20050708”.

  In the above example, “anydevice @ localnetwork” means an arbitrary storage device connected to the local network to which the terminal transmitting / receiving data to / from the electronic bulletin board server belongs, and “/ TVProgramTitle / 20050708” is , The identification information of the content data (the TV program “TVProgramTitle” broadcast on July 8, 2005) represented by the hyperlink. In addition, “TVProgramTitle” can be used in various expression methods such as identification information for identifying a television program as described above, that is, program information used in EPG, G code, content ID, broadcast station name, and the like. is there.

  From such a hyperlink, the terminal 111 acquires content data identification information, and reads the content data from the home network 101 to which the terminal belongs. Detailed operation will be described later.

  As shown in FIG. 2, the terminal 111 has a communication interface 111a for transmitting / receiving data to / from a storage device or server connected to the home network 101 or the public network 102, and a display for displaying an electronic bulletin board. 111b, an identification information acquisition unit 111c that acquires identification information of content data from the electronic bulletin board, a content data reading unit 111d that reads content data from the HDD recorder 113 connected to the home network 101, and the read content data Is provided to the television 112 for display (display).

The above is the configuration of the network system according to the first embodiment of the present invention.
Next, the operation of the network system according to the first embodiment of the present invention will be described with reference to FIGS. FIG. 3 is a flowchart showing the operation of the terminal 111 according to the first embodiment of the present invention. In the following description, it is assumed that devices on the home network 101 are capable of data communication with each other. However, such data communication on the home network 101 is, for example, each device on the home network 101. Can be realized by transmitting and receiving data such as control messages with the IP address as the destination. In this case, for example, in the case where a storage device that records a television program among the devices on the home network 101 is found, the storage that records and stores the television program from the terminal 111 to the device on the home network 101. The following operation may be performed with a storage device that transmits a request message for requesting a response as to whether or not the device is transmitted by multicast and transmits a response message affirmative thereto. The same applies to the display device.

  First, the user displays an electronic bulletin board on the display unit 111b of the terminal 111 using a Web browser of the terminal 111 (step S101). FIG. 4 is a display example of an electronic bulletin board. Such display of the electronic bulletin board on the display unit 111b of the terminal 111 may be performed by, for example, a widely used Web browser.

  Next, the identification information acquisition unit 111c of the terminal 111 acquires the identification information of the content data from the electronic bulletin board server 121 in response to an instruction from the user such as clicking on a hyperlink on the electronic bulletin board (step S102). . If the data on the website of the electronic bulletin board provided by the electronic bulletin board server 121 is already stored in the memory (not shown) of the terminal 111, the terminal 111 is not accessed without newly accessing the electronic bulletin board server 121. The identification information of the content data may be acquired from the data stored in the memory.

  When the identification information acquisition unit 111c of the terminal 111 acquires the identification information of the content data in this way, the content data reading unit 111d of the terminal 111 then acquires the content acquired from the HDD recorder 113 connected to the home network 101. The content data corresponding to the data identification information is retrieved and read (step S103).

  As a method for searching for and reading content data corresponding to the identification information of the acquired content data from the HDD recorder 113 connected to the home network 101, for example, content that the HDD recorder 113 has in advance from the HDD recorder 113 to the terminal 111 can be used. A method of transmitting data identification information is conceivable. That is, content data identification information transmitted from the HDD recorder 113 is stored in the memory of the terminal 111 as a content data list table. Then, when reading the content data corresponding to the specific identification information, the content data stored in the HDD recorder 113 may be read based on this table.

  FIG. 5 shows an example of the content data list table. Here, for each program name, the broadcast time of the program name, the broadcast station, information on the stored storage device, and the time when the table was last updated are stored. The content data list table stores all programs broadcast from “2005/01/01” to “2005/07/14” by the “ccc” broadcasting station, such as “ccc-all”. Identification information indicating that the content is present may be stored in association with the content data. Such a content data list table is desirably updated periodically so that the latest contents are always stored.

  Separately from this, for example, whenever content data is to be read, identification information of the content data is transmitted from the terminal 111 to the HDD recorder 113, and whether or not there is content data corresponding to the HDD recorder 113 is answered. You may do it.

  When there are a plurality of storage devices other than the HDD recorder 113, the identification information of the content data is transmitted from the terminal 111 to the storage device on the home network 101 by multicast (or in order), and the response from each storage device The location of the content data may be searched by receiving. When there are a plurality of storage devices on the home network 102, a so-called home directory server that centrally manages content data stored in these storage devices is provided, and the contents of the terminal 111 are provided. The data reading unit 111d may transmit content data identification information to the home directory server to answer the location of the corresponding content data. Alternatively, a priority order may be given to each storage device, and content data may be retrieved from each storage device in order according to the priority order.

  Further, when the content data stored in each storage device has a difference in image quality due to, for example, different compression rates, the content data having the highest image quality (low compression rate) is read out. It may be. Alternatively, the read content data may be transmitted to the terminal 111 via the home network 101 and displayed on the display unit 111b so that the user can arbitrarily select the content data.

  Here, as described above, the HDD recorder 113 is assumed to be a large-capacity storage device. However, since only a part of TV programs are recorded, content data cannot be found or the HDD recorder that has been stored once is recorded. A case may be considered where it cannot be found because it has been deleted from 113. In such a case, the content data reading unit 111d receives a reply from the HDD recorder 113 that the corresponding content data is not present. And the terminal 111 should just display that the content data cannot be displayed on the display part 111b.

  When the content data reading unit 111d of the terminal 111 reads the content data stored in the HDD recorder 113, the display control unit 111e of the terminal 111 then sends the read content data from the HDD recorder 113 to the home. It is transmitted and displayed on the television 112 on the network 101 (step S104).

  Specifically, first, transmission of content data and a control message indicating the transmission destination (television 112) are transmitted from the display control unit 111e of the terminal 111 to the HDD recorder 113. At the same time, the display control unit 111e transmits a control message instructing the television 112 to receive and display the content data transmitted from the HDD recorder 113.

  The content data may be transmitted to the television 112 directly from the HDD recorder 113 to the television 112. First, the content data to be transmitted is received by the terminal 111 and transferred to the television 112. 112 may be transmitted. At this time, the terminal 111 may perform transfer to the television 112 while displaying the received content data on the display unit 111b, for example.

  The above is an example of so-called “third-party setup” in which the third-party terminal 111 transmits a control message to the HDD recorder 113 and the television 112, respectively. Separately from this, for example, a control message for instructing the television 112 to transmit (pull) the content data from the HDD recorder 113 to the television 112 and to receive and display it is displayed. The content data may be displayed on the television 112 by transmitting.

  When there are a plurality of display devices that display content data, for example, information of a plurality of display devices connected to the home network 101 is stored in advance in the terminal 111 so that the user can select from these. May be. That is, for example, a screen for allowing the user to select a display device as shown in FIG. 6 is displayed on the display unit 111b of the terminal 111, and content data is displayed on the display device selected by the user on this screen. That's fine.

  In the above description, when content data is transmitted from the HDD recorder 113 to the television 112, the content data reproduced by the HDD recorder 113 is transmitted to the television 112 and displayed on the television 112. However, in the case where the television 112 has a content data reproduction function, the content data can be reproduced by the television 112. Further, when the content data stored in the HDD recorder 113 is transferred to the television 112 via the terminal 111, the content data is reproduced on the terminal 111, and the reproduced content data is transferred to the television 112. It is also possible to display it.

  In this way, the content data stored in the HDD recorder 113 is transmitted to the television 112 via the home network 101 and displayed, so that the user can view the content data. Become. At this time, the data transmitted / received between the electronic bulletin board server 121 and the terminal 111 via the public network 102 is content data identification information, and the content data itself is not transmitted / received via the public network 102. . Therefore, as described above, for example, there is no problem that the content data cannot be transmitted / received via the public network because the content data capacity exceeds the capacity that can be transmitted / received via the public network.

  As described above, according to the network system including the terminal 111 according to the first embodiment, the terminal 111 acquires the identification information of the content data from the electronic bulletin board server 121 connected to the public network 102, and the content data Based on the identification information, the content data stored in the storage device (HDD recorder 113) connected to the home network 101 can be displayed on the television 112 via the home network 101. Therefore, even if the content data cannot be transmitted / received via the public network due to the type or capacity of the content data, the user can easily view the content data.

  In the above-described embodiment, the content data is displayed on the television 112 in response to an instruction from the terminal 111, but may be displayed on the display unit 111b of the terminal 111. In this case, first, the terminal 111 causes the HDD recorder 113 to transmit the content data read by the content data reading unit 111d to the terminal 111. The terminal 111 receives the content data transmitted from the HDD recorder 113 and displays it on the display unit 111b.

  In the above-described embodiment, the content data is read from the HDD recorder 113 connected to the terminal 111 via the home network 101. However, the content data is also stored in the memory of the terminal 111 together with the identification information. In such a case, the content data reading unit 111d may search the memory to read the content data.

  In the above-described embodiment, the embodiment in which the identification information of the content data is acquired from the electronic bulletin board server as the WWW server has been described. However, the WWW server may not be the electronic bulletin board server. That is, for example, even if a server that provides a website (such as a homepage that does not have an electronic bulletin board) that does not allow others to write, content data identification information is described in a hyperlink format. It is also possible to acquire content data identification information from a hyperlink so that the content data can be viewed.

  Further, in the above-described embodiment, the television program in which the content data is broadcast and the storage device are HDD recorders. However, the content data may be, for example, music or still images, and the storage device may be, for example, a memory. AV equipment etc. having

  In the above-described embodiment, the identification information of the content data is expressed as a hyperlink on the electronic bulletin board. However, it is not necessarily expressed as a hyperlink. For example, even if the identification information is expressed as a simple character string that is not a hyperlink on the electronic bulletin board, the terminal 111 only needs to have a function of specifying and selecting the character string. As the method, for example, as shown in FIG. 7, the identification information of the content data described on the electronic bulletin board can be selected using a mouse cursor or the like, and the identification information acquisition unit 111b selects the selected information. What is necessary is just to acquire the identification information of content data from a part.

  In addition, the hyperlink is not the content data identification information directly described as a character string on the electronic bulletin board. For example, as shown in FIG. 8, the identification information is embedded in the document data. The identification information may be acquired by clicking the character string of the part. For example, when HTML is used as the document description language, the identification information is embedded in the document data as follows: “<A HREF=“anydevice@localnetwork/TVProgramTitle/2005050708”> here </A> Can be realized.

  The terminal 111 can also be realized by using, for example, a general-purpose computer device as basic hardware. That is, the identification information acquisition unit 111c, the content data reading unit 111d, and the display control unit 111e can be realized by causing a processor mounted on the computer device to execute a program. At this time, the terminal 111 may be realized by installing the above program in a computer device in advance, or may be stored in a storage medium such as a CD-ROM or distributed via the network. The program may be implemented by appropriately installing it in a computer device. Further, the terminal 111 may have a function as a television or a function as an HDD recorder in addition to the functions described above.

(Second Embodiment)
In the first embodiment described above, the terminal 111 acquires content data identification information from the electronic bulletin board server, and uses this to read content data from the HDD recorder 113.

  In the second embodiment, in addition to the content data identification information, in order to display only a part of the content data, the information for specifying the part and the display speed (playback speed) for displaying the content data are specified. When the information to be used and the content data include multiple languages (for example, in the case of an audio multiplex broadcast television program), the information for specifying the language to be used and the content data are displayed. An embodiment in which information specifying a presentation method of content data, such as additional information to be displayed (inserted), is also obtained from the electronic bulletin board server 121 and content data is presented based on such information will be described.

  In the network system according to the second embodiment of the present invention, in the network system according to the first embodiment, the identification information acquisition unit 111c of the terminal 111 presents the content data as described above together with the identification information of the content data. The difference is that information specifying the method is also obtained, and the display control unit 111e controls the HDD recorder 113 and the television 112 so as to present the content data according to the method.

  First, in the electronic bulletin board, an example of a hyperlink including information specifying the content data presentation method as well as the content data identification information as described above is shown below.

  First, as a hyperlink including information for specifying a part to be displayed of content data used for displaying only a part of the content data, for example, “anydevice @ localnetwork / TVProgramTitle / 2005050708 / 09300-093030” is used. An expression may be used. The above example is an example in which the portion from 9:30 to 9:30:30 of the TV program “TVProgramTitle” broadcast on July 8, 2005 is specified. The display control unit 111f transmits only the specified part of the content data read by the content data reading unit 111d from the HDD recorder 113 to the television 112 for display.

  In addition, for a specific AV device, for example, so-called “metadata” that can specify a specific scene of content data may be defined for each model or manufacturer. In such a case, it is possible to specify and display a part of the content data using the metadata.

  For example, a storage device called “DEF” of “ABC” assigns numbers sequentially as metadata for each television program stored, for example, for each corner of a television program or for each news in a news program. Let's consider the case where it is memorized. In this case, for example, the expression “ABC-DEF @ localnetwork / TVProgramTitle / 20050708 / 093000-100000 / shot-number = 3” is used as a hyperlink including information for specifying a portion to be displayed of content data. Can do.

  In the above example, “ABC-DEF @ localnetwork” means a storage device called “DEF” of “ABC” connected to the local network (ie, home network 101) to which the terminal 111 belongs. Then, “TVProgramTitle / 2005050708 / 093000-100000 / shot-number = 3” is used to express “3rd program from 9:30 to 10:00 of the program“ TVProgramTitle ”broadcast on July 8, 2005. The second shot (scene) "is specified. The content data reading unit 111d of the terminal 111 reads the content data from the storage device “DEF” of “ABC company” on the home network 101, and the display control unit 111f reads the content read by the content data reading unit 111d. Only the part specified in this way is transmitted to the television 112 and displayed.

In this way, it is possible to designate and display a specific scene using “metadata” defined for each specific model.
Next, for example, the expression “anydevice @ localnetwork / TVProgramTitle / 2005050708 /? Speed = 2” may be used as a hyperlink including information specifying the speed (reproduction speed) for displaying content data. The above example is an example in which a television program “TVProgramTitle” broadcast on July 8, 2005 is designated to be displayed at twice the normal speed. The display control unit 111f causes the content data read by the content data reading unit 111d to be transmitted from the HDD recorder 113 to the television 112, and controls the HDD recorder 113 to reproduce and display the content data at twice the normal speed. Let

  Next, when the content data includes a plurality of languages (for example, when the content data is a TV program of audio multiplex broadcasting), as a hyperlink including information specifying the language to be used, for example, “anydevice” @ Localnetwork / TVProgramTitle / 20050708 /? Audio = sub ”may be used. The above example is an example in which a television program “TVProgramTitle” broadcast on July 8, 2005 is designated to be output with sub-audio. The display control unit 111f transmits the portion corresponding to the sub-audio in the content data read by the content data reading unit 111d from the HDD recorder 113 to the television 112 for output.

  Next, as a hyperlink including additional information to be inserted when content data is displayed, for example, when the expression “anydevice @ localnetwork / TVProgramTitle / 20050708” is used and described in a document, the document description Using HTML as the language, “<tt = text“ I like this actor in this scene the most ”content URI =“ anydevice @ localnetwork / TVProgramTitle / 20050708 ”begin =“ 09:30:30 ”duration =“ 30:00 “Location =“ (XXX, YYY) ”medium“ arrow ”>
