Information providing apparatus and information providing method

[0001] 1. Field of the Invention

[0002] The present invention relates to technology for providing related information that is related to advertising content associated with video content.

[0003] 2. Description of the Related Art

[0004] There are following conventional technologies for providing detailed information related to a portion of content.

[0005] The first technology is disclosed in information providing apparatus (Japanese laid-open patent application No.9-160852). In the technology, a receiving terminal for receiving broadcasted signals and a user terminal (computer) are combined so that the user can request, by an easy operation, detailed information on a program that the user is viewing. More particularly, the user terminal sends a pair of a channel number and a user request obtained time to an address server that provides an address of detailed information of the program. The address server converts the received pair into an address of the detailed information and provides the address to the user. In addition, the server can provide the address in response to a request of the user after a lapse of a time.

[0006] Next technology is disclosed in system for reproducing AV information and reproducing method of the system (Japanese laid-open patent application No.9-328596). In the technology, a mark (Web mark) is displayed if detailed information (Web page) can be provided while reproducing image content from a recording medium. The reproducing apparatus can obtain the detailed information when the user clicks the mark.

[0007] In reproducing system and reproducing terminal apparatus (Japanese laid-open patent application No.10-62724), a reproducing terminal reproduces a data file (music and video), and detailed information related to the data file is downloaded from an information server and the detailed information is displayed on the reproducing terminal. More particularly, the reproducing terminal sends identification information of the data file to the information center, and the information center sends an URL of the detailed information to the reproducing terminal on the basis of the received identification information.

[0008] However, there are following problems in the above-mentioned conventional technologies.

[0009] In the above-mentioned information providing apparatus (Japanese laid-open patent application No.9-160852), the system is assumed to be used only for broadcasting media. In addition, since the channel number and the time are used for detecting an operation indicating the detailed information request by the user, it is impossible to apply this system to package media.

[0010] As to the above-mentioned system for reproducing AV information and reproducing method of the system (Japanese laid-open patent application No.9-328596), the detailed information can be displayed only when the Web mark is displayed. Therefor, it is impossible to display the detailed information asynchronously at any timing and it is impossible to display the detailed information on an terminal other than the reproducing apparatus.

[0011] As to reproducing system and reproducing terminal apparatus (Japanese laid-open patent application No.10-62724), it is impossible to display detailed information only for reproduced content that the user is interested in. In addition, it is impossible to display the detailed information at desired timing.

[0012] In addition, according to the conventional technologies, although information that the user is interested in can be recorded, related information can not be provided without user's request. Thus, if the user forgets the fact that the user has recorded information, the recorded information can not be used effectively.

[0013] An object of the present invention is to provide an information providing technique for providing, to a desired terminal at desired timing, information on advertising content in which the user is interested in while the user is viewing video content.

[0014] The above object is achieved by an information providing system for providing related information that is related to advertising content associated with video content, the information providing system comprising a user terminal and a center terminal, the user terminal including:

[0015] a part for obtaining user information for identifying a user;

[0016] a part for obtaining content information for identifying the video content;

[0017] a part for obtaining locating information for locating advertising content corresponding to input by the user;

[0018] a part for sending the user information, the content information and the locating information as mark information;

[0019] the center terminal including:

[0020] an advertising information storing part for storing, for each video content, identification information of advertising content and locating information corresponding to the advertising content;

[0021] a storing part for obtaining identification information of advertising content from the advertising information storing part by using the content information and the locating information included in the mark information, and storing the identification information or related information on the advertising content in which the stored identification information or related information is associated with the user information included in the mark information;

[0022] a sending part for sending the related information on the basis of the user information.

[0023] According to the present invention, based on mark information sent from the user terminal of a user, the center terminal stores information related to advertising content that the user is interested in for the user. Thus, the user can obtain the information related to the advertising content at any timing by using desired terminal.

[0024] For example, the center terminal sends the related information to a viewing terminal in response to receiving a viewing request that includes user information from the viewing terminal, or the center terminal may send related information corresponding to a user to a viewing terminal of the user at a predetermined notification time.

[0025] The predetermined notification time may be a date and time that is specified by the user or a predetermined periodic date and time, or, if content on the advertising content is unscreened, the predetermined notification time is a date and time close to a release date of the content on the advertising content.

[0026] The user terminal may include a reproducing part for reproducing video content in a package medium or received via broadcasting. In this case, the locating information for locating advertising content is reproducing position information corresponding to the advertising content in the video content.

[0027] The center terminal may include a related information storing part for storing the related information in which the related information is associated with identification information of the advertising content;

[0028] wherein the center terminal obtains the related information from the related information storing part by using the identification information of the advertising content.

[0029] In addition, the user terminal may obtain the content information for identifying the video content from input by the user, from digital data embedded in the package medium, from other terminal, or from information included in broadcasted information.

[0030] The above-mentioned object can be also achieved by a center terminal to be used in an information providing system for providing related information that is related to advertising content associated with video content, the center terminal including:

[0031] a part for receiving user information for identifying a user, content information for identifying the video content and locating information for locating advertising content;

[0032] an advertising information storing part for storing, for each video content, identification information of advertising content and locating information corresponding to the advertising content;

[0033] a storing part for obtaining identification information of advertising content from the advertising information storing part by using the content information and the locating information included in the mark information, and storing the identification information or related information on the advertising content in which the stored identification information or related information is associated with the user information included in the mark information;

[0034] a sending part for sending the related information on the basis of the user information.

[0035] In addition, the above-object can be also achieved by a user terminal for providing related information that is related to advertising content associated with video content, the user terminal including:

[0036] a part for obtaining user information for identifying a user;

[0037] a part for obtaining content information for identifying the video content;

[0081] In the following, embodiments of the present invention will be described with reference to figures.

[0082] First Embodiment

[0083] First, the principle of the first embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a schematic of a package media content detailed information providing system of the first embodiment. The package medium is a recording medium such as an optical magnetic disk or a magnetic tape that stores content such as video, music and games and is provided for sale or rental.

[0084] Content, as referred to in accordance with the present invention, is understood by one skilled in the art as being information that is intended for presentation to a user, either visually or audibly or as an audiovisual presentation.

[0085] The system is for obtaining detailed information of the content in the package medium. The system includes a media reproducing apparatus 200, a viewing terminal 300 and a center terminal 100.

[0086] The media reproducing apparatus 200 includes a first user input detection part 230, a user ID obtaining part 240, a package ID obtaining part 250, a reproducing position information obtaining part 260, a mark information sending part 270. The first user input detection part 230 detects input from a user. The user ID obtaining part 240 obtains a user ID for the user. The package ID obtaining part 250 obtains a package ID from user input or from digital data embedded in the package medium. The reproducing position information obtaining part 260 obtains reproducing position information in response to user input for a portion of content that the user is interested in. The mark information sending part 270 sends the user ID, the package ID and the reproducing position information as mark information.

[0087] The center terminal includes a receiving part 110, an advertising information holding part 150, a mark information holding part 140, a content information management part 160 and a mark content information producing/sending part 170.

[0088] The receiving part 110 receives information from other apparatuses. The advertising information holding part 150 holds, for each package ID, reproducing interval information for advertising content that is included in the package medium and content IDs of advertising content in which each piece of the reproducing interval information is associated with the corresponding content ID. The mark information holding part 140 sends the received package ID and the reproducing position information to the advertising information holding part 150 to request for identifying content that the user is interested in, and stores the user ID and the content ID of the identified content by associating the user ID with the content ID. The content information management part 160 stores, for each content, information including title, rental fee, rental availability and reservation availability in which these pieces of information is associated with the content ID. The mark content information producing/sending part 170 identifies a content ID by referring to the mark information holding part on the basis of the user ID included in a viewing request from the receiving part 110, searches the content information management part 160 by using the content ID, and sends information related to the content ID to the source of the viewing request.

[0089] The viewing terminal 300 includes a second user input detection part 310, a viewing request part 330 and a display part 340. The second user input detection part 310 detects user input. The viewing request part 330 sends a viewing request including a user ID to the center terminal 100. The display part 340 displays a response from the center terminal 100.

[0090] Next, an overview of the operation of the system will be described with reference to a sequence chart shown in FIG. 2.

[0091] The media reproducing apparatus 200 detects a user ID input by the user and stores the user ID in step 1, and obtains the package ID from an input of the user or from digital data embedded in the medium in step 2. Then, the media reproducing apparatus 200 reproduces content in the medium and obtains reproducing position information in the medium in response to input from the user in step 3, and sends the user ID, the package ID and the reproducing position information to the center terminal as mark information in step 4.

[0092] The center terminal identifies the user from the mark information and stores the mark information in step 5. When the center terminal receives a viewing request including the user ID from the viewing terminal 300 in step 6, the center terminal identifies the user from the user ID in step 7 and searches for package ID and reproducing position information corresponding to the user ID in step 8. Then, the center terminal specifies a content ID of the advertising content that the user is interested in by using the package ID and the reproducing position information in step 9. Then, the center terminal obtains information related to the content ID from a storing part that manages information related to content in step 10, then sends the information to the viewing terminal 200 in step 11. The viewing terminal 200 displays the response from the center terminal 100 in step 12.

[0093] In the following, the present embodiment will be described more particularly. Following description will be given taking a rental service of a package medium as an example.

[0094] The package medium in this embodiment is, for example, a rental video, a DVD and the like. The user is interested in an advertising content such as a preview that is associated with main content in the package medium. While the user is watching content in the package medium, if the user is interested in a portion of the content, information on the portion of the content is stored in the center terminal only by performing easy operation by using an remote controller and the like, so that the user can obtain detailed information on the advertising content (portion of the content) at any timing the user wants.

[0095] The detailed information may be the title and the rental fee, rental availability, or rental reservation availability for the advertised content at the time of the request by the user.

[0096] FIG. 3 shows a system configuration of the first embodiment of the present invention.

[0097] The system of the first embodiment includes the media reproducing apparatus 200, the center terminal 100 and the viewing apparatus 300. The media reproducing apparatus 200 reproduces content in a medium such as a video and a DVD that the user borrowed. The center terminal stores information related to the advertising content that the user is interested in, and provides the information or receive reservation request of the advertised content according to a request by the user. The viewing terminal 300 is used for requesting the detailed information of the advertising content at any timing from the center terminal 100.

[0098] These terminals are connected by communication circuit such as the Internet. Although the media reproducing apparatus 200 and the viewing apparatus 300 are explained separately in this embodiment, these may be integrated to one terminal.

[0099] In the following, each apparatus shown in FIG. 3 will be described.

[0100] The media reproducing apparatus 200 includes a media reproducing part 210, a display part 220, a user input detection part 230, a user ID obtaining/storing part 240, a package ID storing part 250, a reproducing position information obtaining part 260 and a mark information sending part 270.

[0101] The media reproducing part 210 has an insertion opening for inserting a medium such as a videocassette or DVD, and reproduces video data in the medium.

[0102] The display part 220 displays the reproduced video data, and displays an operation menu and information for requesting the user to check operation information.

[0103] The user input detection part 230 detects a user ID and a package ID input by the user, and detects user's input for indicating advertising content.

[0104] The user ID (UID) is assigned beforehand by the system for a user who registers in the system. The user ID is used for identifying the user. The package ID (PID) is assigned beforehand to a package medium that the user borrowed for example.

[0105] More particularly, the user ID (UID) can be input as character string including numerals and/or alphabets by using a remote controller or a keyboard. The user input detection part 230 can detect the character string. In addition, when the user ID is written on a member card of the user as barcode, an barcode reader as the user input detection part 230 can read the barcode as the user ID.

[0106] In the same way, the package ID can be input as character string that is written on the package, and the user input detection part 230 can read it. In addition, if the ID is written as barcode, the barcode reader can read it. In addition, the package ID may be embedded as digital data in the medium.

[0107] The user ID obtaining/storing part 240 obtains and stores the user ID (UID) detected by the user input detection part 230. The user ID obtaining/storing part 240 may stores user IDs (UIDs) for each media reproducing apparatus beforehand.

[0108] The package ID storing part 250 obtains and stores the package ID (PID) that is obtained by the user input detection part 230 or obtained from digital data embedded in the medium.

[0109] The reproducing position information obtaining part 260 obtains reproducing position information (T) when detecting user's input for interested advertising content. The reproducing position information (T) is, for example, a relative time in whole video content. The user's input may be performed by pushing a pause button of the remote controller.

[0110] The mark information sending part 270 produces mark information (M) that includes the user ID (UID), the package ID (PID) and the reproducing position information (T), and sends the mark information to the center terminal 100.

[0111] In this embodiment, although the components are included in one apparatus, all of a part of the user input detection part 230, the user ID obtaining/storing part 240, the package ID storing part 250, the reproducing position information obtaining part 260 and the mark information sending part 270 can be included in another apparatus or in a card. In such a case, a communication mean such as infrared ray or card reader becomes necessary between the another apparatus or the card and the media reproducing apparatus 300. As the another apparatus, a mobile terminal such as a mobile phone and PDA can be used. As the card, an IC card and a magnetic card can be used. An example will be described later in a second embodiment.

[0112] In addition, although one center terminal is shown in this embodiment, the number is not limited to one. A plurality of center terminal can be provided. For example, the center terminals may be provided for each package production company, or for each rental company. For example, it can be assumed that a connection destination is shown on the package, or on a user card issued by a rental company.

[0113] The center terminal 100 includes a receiving part 110, a user identification part 120, a user information management part 130, a mark information storing part 140, an advertising information storing part 150, a content information management part 160, a mark content information producing/sending part 170, and a reservation management part 180.

[0114] These components are not necessarily included in one apparatus, and may be included separate apparatuses. For example, if the company has a plurality of stores as branches, management of user information, rental availability and reservation availability management may be performed in each store, and storing mark information may be performed in one store.

[0115] The receiving part 110 receives the mark information (M) from the media reproducing apparatus 200, and receives viewing request (L) or reservation request (R) from the viewing terminal 300. The receiving part 110 sends a user ID (UID) included in the information or request to the user identification part 120. When the user is identified, the receiving part 110 requests the mark information storing part 140 to store the mark information (M) when receiving the mark information (M). When receiving the viewing request (L), the receiving part 110 requests the mark content information producing/sending part 170 to produce mark content information (C). When receiving the reservation request (R), the receiving part 110 requests the reservation management part 180 to reserve content.

[0116] The mark information storing part 140 requests the advertising information storing part 150 to identify content that the user is interested in by sending the package ID (PID) and the reproducing position information (T) to the advertising information storing part 150. Then, the mark information storing part 140 stores the user ID (UID) and a content ID (CID) of the identified content. The content ID (CID) is an ID that is assigned to each content to identify content uniquely.

[0117] The advertising information storing part 150 stores, for each package ID, content IDs and corresponding pieces of reproducing interval information.

[0118] The content information management part 160 stores, for each content ID, pieces of information such as title, rental fee, rental availability, reservation availability and the like.

[0119] The mark content information producing/sending part 170 requests stored data from the mark information storing part 140 by sending the user ID (UID) included in the viewing request (L) to the mark information storing part 140. Then, the mark content information producing/sending part 170 prepares content information (marked content information (C)) and sends it to the viewing terminal 300. The marked content information includes tile, rental fee, rental availability, reservation availability, content ID (CID), recommended content and the like for the marked content. The information may include advertising video that the user viewed when the content was marked.

[0120] The reservation management part 180 manages reservation by using the user ID (UID), the content ID (CID) and reservation date and time (D) that are included in the reservation request (R). The reservation date and time (D) are date and time that the user wants to reserve content. At this time, user authentication may be performed by using a password and the like.

[0121] The viewing terminal 300 includes a user input detection part 310, a user ID obtaining and storing part 320, a marked content information viewing request part 330, a display part 340 and a reservation request part 350.

[0122] The user input detection part 310 and the user ID obtaining/storing part 320 are the same as those of the media reproducing apparatus 200.

[0123] The marked content information viewing request part 330 produces the viewing request (L) including the user ID (UID) and sends the viewing request to the center terminal 100 for requesting information on the marked advertising content.

[0124] The display part 340 receives the marked content information from the center terminal 100 and displays it. The reservation request part 350 produces a reservation request (R) that includes reservation data and time, the content ID and the user ID (UID), and sends the reservation request (R) to the center terminal 100. The reservation request part 350 may sends a password input by the user to the center terminal 100 according to user authentication request by the center terminal 100.

[0125] In the following, procedure for the process of this embodiment will be described with reference to FIGS. 4-8.

[0126] FIG. 4 shows a flowchart showing the operation of the media reproducing apparatus in the first embodiment of the present invention.

[0127] When a video cassette or a DVD that the user rent is set in the media reproducing apparatus 200, the media reproducing apparatus 200 checks whether the user ID obtaining/storing part 240 has the user ID (UID). If it does not have the user ID (No in step 101), the user ID obtaining/storing part 240 detects the user ID input by the user (Yes in step 102), and stores the user ID (step 103). If it has the user ID, the process goes to the next step.

[0128] Next, the media reproducing apparatus 200 obtains the package ID (PID) in step 104 by detecting input by the user or by reading digital data in the media, and reproduces the media in step 105. Then, the media reproducing apparatus 200 detects input performed by the user for marking advertising content that the user is interested in, and obtains reproducing position information (T) at this point in step 107.

[0129] As mentioned before, for marking the advertising content, various easy method can be used, for example, pushing pause button by using a remote controller. Then, the media reproducing apparatus 200 produces mark information (M) by using the user ID (UID), the package ID (PID), and the reproducing position information (T), and sends the mark information (M) to the center terminal 100 in step 108. Next, the operation of the center terminal 100 will be described.

[0130] FIG. 5 shows a flowchart of the operation of the center terminal according to the first embodiment of the present invention.

[0131] The center terminal waits for the mark information (M) from the media reproducing apparatus 200, viewing request (L) from the viewing terminal 300, or the reservation request. When the center terminal receives the mark information (M) (Yes in step 201), the center terminal identifies a user by using the user ID (UID) included in the mark information (M) in step 202. In the user identification process, the user identification part 120 that receives the user ID (UID) from the receiving part 110 inquires the user information management part whether the user ID is registered or not. If the user ID is not registered, the center terminal may sends information for causing the media reproducing apparatus 200 to display a screen for performing registration by the user.

[0132] After that, the center terminal performs mark information storing process in step 203. FIG. 6 shows a flowchart of this process.

[0133] The mark information storing part 140 receives the mark information (M) from the receiving part 110 in step 301, and sends the package ID (PID) and the reproducing position information (T) included in the mark information (M) to the advertising information storing part 150. Then, the mark information storing part 140 obtains a content ID (CID) corresponding to the target advertising content in step 302. FIG. 7 shows an example of data stored in the advertising information storing part 150. As shown in FIG. 7, the advertising information storing part 150 stores reproducing positions and corresponding content IDs for each package ID (PID).

[0134] Then, the mark information storing part 140 stores the obtained content ID (CID) and the user ID (UID) in which the obtained content ID (CID) is associated with the user ID (UID) in step 303. At this time, the mark information storing part 140 may store time indicated by a clock in the system as the date and time when the marking is performed. In addition, a data area for storing a flag for determining whether a video corresponding to the content has been rent may be provided. FIG. 8 shows an example of data stored in the mark information storing part 140. Although FIG. 8 shows an example in which a user provide one mark, the mark information storing part 140 may manage a plurality of mark information for each user. In response to a viewing request, when content is identified by a user ID, a plurality of pieces of content may be identified for the user ID, in which the plurality of pieces of content are corresponds to the user ID in the mark information storing part 140. Thus, all of content IDs corresponding to the user ID may be displayed on the viewing terminal 300. In addition, some pieces of content may be selected. For example, by using the flag showing whether the video has been rent or not, a content ID that has been rent may not be displayed.

[0135] Next, the center terminal 100 waits for receiving a viewing request (L) from the viewing terminal. When the center terminal 100 receives the viewing request from the center terminal 100 in step 204, the center terminal 100 performs user identifying process by using the user ID (UID) included in the request (L) in step 205. This process is the same as that described before.

[0136] Then, the center terminal 100 produces marked content information (C) and sends it to the viewing terminal 300 in step 206. This process will be described with reference to FIG. 9.

In the reservation receipt process, the reservation management part 180 receives the reservation request (R) from the receiving part 110, and makes a reservation for rental of the content by using the user ID and the content ID (CID), reservation date and time, and reservation availability information, in which the user ID (UID) and the content ID (CID) and the reservation date and time (D) are included in the reservation request (R), and the reservation availability information is stored in the content information management part 160.

[0140] FIG. 11 is a flowchart showing the operation of the viewing terminal according to the first embodiment of the present invention.

[0141] First, the viewing terminal obtains a user ID (UID). This process is the same as that in the media reproducing apparatus 200.

[0142] The viewing terminal produces a viewing request by using the user ID (UID), and sends the request to the center terminal in steps 503 and 504. In response to the request, the viewing terminal receives marked content information (C) from the center terminal and displays the information on the display part 340 in step 505. After that, if the viewing terminal detects user input for performing rental reservation in step 506, the viewing terminal produces a reservation request (R) by using the user ID, the content ID (CID) included in the marked content information (C), and the reservation date and time input (D) by the user, and sends the viewing request (R) to the center terminal 100 in step 507. In this step, the viewing terminal may receive, from the center terminal 100, a request for sending a password, and detect input from the user and send the input password to the center terminal 100. If the viewing terminal does not receive input from the user for performing rental reservation, the process ends.

[0143] FIG. 12 is a sequence chart between the media reproducing apparatus and the center terminal according to the first embodiment of the present invention.

[0238] The record request receiving part 810 receives a record request (R) from the mobile terminal 700, and requests the user information management part 820 to identify the user by sending the user information (U) included in the request (R) to the user information management part 820. In addition, the record request receiving part 810 requests the preview information management part 830 to identify content (recorded content information (RC)) that the user is interested in by sending the showing content information (C), time information (T) and the showing location information (L) to the preview information management part 830. In addition, record request receiving part 810 sends the showing location information (L) to the record part 860 to request to record the information.

[0239] The user information management part 820 registers user information according to the user's request beforehand, and stores notification address (A) with user information (U). The notification address (A) is used for sending information on recorded content at another time. The user information (U) may be provided to the terminal beforehand, or may be provided from the center terminal 800 at the time of registration. When the user information management part 820 receives the user information (U) from the record request receiving part 810, the user information management part 820 identifies a notification address (A) that is associated with the user information (U), and sends the notification address (A) to the record part 860.

[0240] The preview information management part 830 stores, for each showing location, showing schedule and information on previews. FIG. 26 shows an example of the data. For each piece of content information, the preview information management part 830 stores a start time and an end time of the main content and a start time and an end time of each preview corresponding to the main content, and content information of each preview. Data in the field of the main content information (C) and data in the preview content information are provided for identifying content uniquely. When the preview information management part 830 receives the showing content information (C), time information (T), the showing location information (L) from the record request receiving part 810, the preview information management part 830 identifies recorded content information (RC) by using the above-mentioned information, and sends the identifies recorded content information (RC) to the related information storing part 840.

[0241] The related information storing part 840 includes a related information table 841 for identifying related information (CI) by using the recorded content information (RC). The related information may include at lease one of title, performer list, outline, static image and the like. When the related information storing part 840 receives the recorded content information (RC) from the preview information management part 830, the related information storing part 840 identifies related information (CI) corresponding to the recorded content information (RC) by referring to the related information table 841, and sends the related information (CI) to the record part 860. FIG. 27 shows an example of the related information table 841.

[0242] When the record part 860 is requested to record content information by receiving the showing location information (L) from the record request receiving part 810, the record part 860 receives the notification address (A) from the user information management part 820 and receives the related information from the related information storing part 840, and stores these pieces information. At this time, date and time when the related information (CI) will be sent to the user are specified. More specifically, for example, the date and time are specified to be near the release date of the content if the content has not been released. In addition, if the content can not be specified, an operator of the center terminal 800 may record the content information manually later. In addition, the center terminal may request the user to input date and time when the user wants to receive notification, such that the user can specify the desired date and time. FIG. 28 shows an example of recorded data in the record part. The record part 860 periodically receives, from the notification information checking part 850, a notification information checking request (CF). When the record part has information to be sent at the time, the record part sends proper related information (CI), showing location information (L), and notification address (A) to the notification part 870 to request the notification part 870 to send these pieces of information. The notification information checking request (CF) is used by the notification information checking part 850 for periodically checking whether there is information to be sent in the record part 860, and the notification information checking request (CF) includes time information.

[0243] The notification information checking part 850 periodically produces the notification information checking request (CF) that includes time, and checks whether the record part 860 includes information to be sent.

[0244] The notification part 870 receives the related information and the showing location information (L) from the record part 860, and produces notification information (I) including these pieces of information. In addition, the notification part 870 receives the notification address (A) at the same time so as to identify the user terminal (mobile terminal 700) to send the notification information (I).

[0261] FIG. 36 shows a system configuration according to the sixth embodiment of the present invention.

[0262] The system shown in the figure includes a viewing terminal 900 by which the user watches the video, a center terminal 800 and a mobile terminal 1000 that receives notification from the center terminal 800. In this embodiment, although the viewing terminal 900 and the mobile terminal 1000 are described separately, these may be configured as one terminal.

[0263] The configuration of the viewing terminal 900 is almost the same as that of the mobile terminal in the fifth embodiment. They are different in that the viewing terminal 900 includes a video receiving part 910 and a content information storing part 920.

[0264] If the video that the user watches is broadcasted by radio, the video receiving part 910 receives the broadcasted video signal and displays video image. At this time, the video receiving part 910 obtaines a tuned channel number (CH) and passes the channel number to the content information storing part 930. The content information storing part 930 stores the channel number (CH).

[0265] If the viewing terminal 900 receives the video from a communication network, the video receiving part 910 receives the video signal and content information (CI) for uniquely identifying the video, in which the content information corresponds to the showing content information of the fifth embodiment. Then, the video is displayed and the video receiving part 910 passes the content information to the content information storing part 930. The content information storing part 930 stores the content information.

[0266] After the user input part 940 detects the user input, the time information obtaining part 950 obtains the time information (T). Other parts are the same as those in the fifth embodiment.

[0267] The mobile terminal 1000 is the same as the configuration of the fifth embodiment including the notification receiving part 760, the display part 770, the recorded content information storing part 780.

[0268] The configuration of the center terminal 800 is the same as that in the fifth embodiment. Data in the preview information management part 830 in the center terminal 800 is data in which time is associated with CM for each channel in the case of radio broadcast or for each destination such as URL in the case of broadcast via the communication network. FIG. 37 shows an example of the data. Different from the fifth embodiment, recorded content is not the preview but CM. That is, instead of the recorded content information (RC), CM information (CM) is identified so as to identify related information (CI) by using a table in which CM information (CM) is associated with related information (CI).

[0269] The notification time when the CM information is notified of to the user may be determined to be predetermined date and time after the release date and time of the CM information, or user specified date and time. In addition, if the record part 860 indicates that the information is to be sent periodically, the date and time may be determined according to the predetermined date and time. Other processes, and sequences are the same as those of the fifth embodiment.

[0270] Seventh Embodiment

[0271] In this embodiment, content such as a preview that is included in a video program that is recorded in a recording medium such as a DVD.

[0272] FIG. 38 shows the system configuration of the seventh embodiment of the present invention.

[0273] The system shown in FIG. 38 is almost the same as the sixth embodiment. The viewing terminal 900 has a video reproducing part 970 instead of the video receiving part 910. A recording medium such as DVD can be set into the video reproducing part 970 which reproduces video signal recorded in the medium. In addition, the viewing terminal 900 obtains package information (C2) instead of the content information (C1) of the sixth embodiment. The viewing terminal 900 may obtain the package information (C2) by reading package information (C2) recorded in the recording medium, or by detecting input by the user. The input by the user may be performed by using a keyboard, infrared ray, near field communication, IC chip or the like.

[0274] The content information storing part 920 stores the obtained package information (C2).

[0275] Time information (T) obtained by the time information obtaining part 950 may be a time relative to the start of the video, or may be a number of a video frame that can identify a potion of the reproduced video.

[0276] In the center terminal 800, recorded content information (RC) can be identified by using package data (C2) and time information (T) in the data stored in the preview information storing part 830. An example of the data is shown in FIG. 39.

[0277] The notification time when the CM information for the preview is notified of to the user may be determined to be as a predetermined date and time after the release date and time of the CM information, or user specified date and time. In addition, if the record part 860 indicates that the information is to be sent periodically, the date and time may be determined according to the predetermined date and time.

[0278] Components of the center terminal 800 and the mobile terminal 700, and operations and sequences are the same as those of the sixth embodiment.

[0279] Eighth Embodiment

[0280] Next, the eighth embodiment of the present invention will be described.

[0283] The viewing/mobile terminal 905 includes components of the viewing terminal 900 and components of the mobile terminal 1000. The video reproducing part 975 may be called as a video receiving part in the case where the video reproducing part 975 has a capability described in the sixth embodiment. The operation of the system in this embodiment is the same as that of the sixth or seventh embodiment except that the viewing terminal 900 and the mobile terminal 1000 operate as the viewing/mobile terminal 905.

[0284] As mentioned above, according to the fifth to eighth embodiments, when the user is interested in advertising content that is associated with video content such as a movie, a TV program or the like, the user can record information on the advertising content only by performing a simple operation. In addition, the information can be sent to the user at a proper timing even if the user forgets about recording the information of the content. Thus, it can be avoided to loose an opportunity to view the recorded content.

[0285] As for the provider of the video content, the provider can provide opportunities for the user interested in advertising content to view information at any timing and at the same place.

[0286] The information that is recorded is not limited to information on content. The information may be information related to a product, so that the related information of the product can be sent just before the release of the product.

[0287] The capabilities of each terminal can be realized by installing a program in a computer from a recording medium such as a CD-ROM, a hard disk drive, a flexible disk and the like. The program can be also installed via a network.

[0288] The present invention is not limited to the specifically disclosed embodiments, and variations and modifications may be made without departing from the scope of the present invention.
