Description

  The present invention relates to a program information server, a program information providing system, and a program information providing system for acquiring information related to a television broadcast program, program advertisement, CM, etc. using a broadcast receiving device such as a television receiver or a recording / playback device. The present invention relates to a method and a broadcast receiving apparatus.

  Conventionally, when a TV program is advertised, the TV program is advertised by placing an advertisement for the TV program on a paper medium such as a magazine or newspaper related to the TV program. Also, TV programs are advertised as part of TV broadcasts using TV broadcasts.

  When advertising TV programs using paper media, the listing of TV program advertisements on paper media is excellent, making it easy for viewers to visually grasp TV programs. . For example, when a viewer is interested in a TV program posted on a paper medium and desires to view the TV program, the viewer acquires the broadcast start time and channel of the desired TV program from the paper medium and acquires it. The desired television program is viewed using the broadcast start time and channel.

  Specifically, the viewer stores the broadcast start time and channel acquired from the paper medium, and when the broadcast start time is reached, the viewer stores the desired TV program by setting the channel for storing the TV channel. Can see. Alternatively, the viewer can make a recording reservation on the video tape recorder using the acquired broadcast start time and channel, and the viewer can watch the desired recorded television program.

  As described above, when viewing at the actual broadcast start time, the viewer needs to remember the broadcast start time and channel together with the desired television program until the broadcast start time. Recently, digital broadcasting has started, and there are many TV programs and there are many advertisements for TV programs, so viewers' interest in TV programs that they have become interested in fades with time, and TVs that have become interested once. I often forget the existence of the program itself.

  Then, when advertising a TV program to a viewer who watches at the actual broadcast start time using a paper medium, the viewer forgets with the passage of time even if the TV program is interested in the promotion. However, there are many cases in which the TV program that interests the user once is not viewed, and the advertising effect of the TV program is low.

  In addition, when a viewer watches a desired recorded television program, a recording reservation is necessary, and this recording reservation is complicated. In order to solve this problem, there is a recording reservation device that can easily perform a recording reservation operation using a bar code or an identification number.

  However, since there are many channels and the number of TV programs is large, the viewer forgets the existence of the recorded desired TV program even if the viewer can make a reservation for recording the desired TV program. There is a problem that viewers often do not actually watch TV programs that are interested in the advertisements even though they have been recorded.

  Recently, there are large-capacity recording / playback devices such as DVD recorders that can record a large number of TV programs, and therefore, using this recording / playback device, reservations can be made for TV programs of interest each time. Can be considered.

  However, when a TV program with interest is recorded each time, the number of TV programs to be recorded is large. Therefore, when actually watching the TV program with interest, searching for the TV program is complicated. . For this reason, there is a problem that there are many cases where viewers do not actually watch TV programs that are interested in the advertisements even though they are recorded.

  In other words, when advertising TV programs using paper media, the listability of TV programs is excellent and it is easy for viewers to visually grasp TV programs, but the advertising efficiency of TV programs is poor. There's a problem.

  On the other hand, when advertising a TV program using TV broadcasting, there is an effect that a relatively large number of viewers can watch the TV program. However, because many of the TV programs that are broadcast during TV broadcasts have short broadcast times, even if the TV program that was advertised could interest a large number of viewers, In many cases, it cannot be stored in the viewer's memory. In addition, even if a television program name or the like is stored, the viewer often cannot store the broadcast start time and channel of the television program.

  In other words, when a TV program is promoted using TV broadcasting, a relatively large number of viewers can watch the TV program and can be interested in many viewers. In many cases, viewers cannot actually watch, and there is a problem that the advertising efficiency of the TV program is poor.

  As an invention related to the present invention, Patent Document 1 discloses a mobile phone or a PHS or other mobile communication terminal equipped with a character / image display unit and a television receiver / recording device remote controller integrated with each other. There is disclosed a communication system including a functional portable terminal and a database storing television program related information including a television broadcast program table and information related to the television broadcast program. Further, it is described that television program related information is displayed on the display unit of the high function portable terminal, and the television program can be selected efficiently by using the television program related information.

Further, in Patent Document 2, when a user selects or changes a television channel, a portable terminal transmits a radio signal related to channel selection to the television receiver, and the channel is selected or changed according to the selection or change. The mobile terminal transmits a program-related information acquisition request including user identification information or information on the current position and information on channel selection to the server. When the mobile terminal receives the program-related information from the server, A program related information providing system for displaying the program related information on a display device of a portable terminal is disclosed. Further, it is described that shopping or the like can be performed using program-related information received from the server.
However, although the techniques described in Patent Documents 1 and 2 can select a TV program and acquire information related to a TV program that is currently being broadcast, the advertisement of CMs and other programs that flow during the TV program broadcast. Since it is not possible to identify information on the level of broadcasting material such as commercials, viewers who are once interested in a TV program cannot be linked to actual viewing behavior after that, and the TV program cannot be promoted efficiently. .

The time may be stored in the viewing log DB 340 along with the position information as needed. In this case, the viewing log DB 340 can aggregate the audience rating and the like in real time based on the channel information, the position information, and the time. Further, the viewing log DB 340 can total the recording rate and the recorded viewing rate based on the recording information / recorded program selection information.

  In addition, the viewing log DB 340 matches the viewing log with the purchase history such as electronic commerce using the billing / authentication function provided by the mobile phone company, the consumer questionnaire survey, and the like by the user ID of the mobile phone 200. It is possible to efficiently carry out a survey for associating the viewing history stored in and the actual purchase behavior. Regarding the survey of the audience rating and the like, since the viewing log generated in the viewing log DB 340 is immediately calculated by using the real-time program information server 300, the actual TV viewing fluctuation is investigated almost in real time. can do.

  Furthermore, by using the real-time program information server 300, it is possible to reflect the program organization change data until immediately before the broadcast, so that the audience rating according to the progress of the broadcast program is compared with the conventional audience rating survey method. It is possible to quickly and accurately grasp changes.

  FIG. 5 is a diagram schematically showing the flow of information output from the broadcast station 500 to the real-time program information server 300.

  The internal organization of the broadcasting station 500 is composed of archiving, reporting, production, public relations, sales / organization, organization, and transmission. In the first embodiment, only information output from one broadcasting station 500 to the real-time program information server 300 will be described. However, real-time program information servers from a plurality of broadcasting stations existing in the area related to the program information providing system 1 are described. The same applies to the information output to 300. In the first embodiment, the “station ID” of the broadcasting station 500 is “XX television”, and the broadcasting channel in a predetermined area is “X channel”.

  A program archive CM bank 501 is provided for the archive, a news support system 502 is provided for the news report, a program production system 503 is provided for the production, a public relations promotion DB 504 is provided for the public relations, and a business promotion DB 504 is provided for sales and organization. A release system 505 is provided, a PlayList data server 506 is provided for composition, and an automatic program transmission device 507 is provided for transmission. In these apparatuses and systems, when various types of information are input from each person in charge, the input information is output to the real-time program information server 300.

  Specifically, the program archive CM bank 501 outputs program metadata 364, the news report support system 502 outputs untime information 354, the program production system 503 outputs untime information 354, and the public relations promotion DB 504 displays a program. Advertisement information 362 is output, broadcast system 505 outputs program frame organization information 351, Q sheet organization information 352, program basic information 361, and program material information 363, and PlayList data server 506 outputs playlist information 353. The automatic program transmission device 507 outputs untime information 354.

  Note that the data output from the broadcast station 500 to the real-time program information server 300 can be divided into two groups: organization data and program content data. The organization data is data composed of program frame organization information 351, Q sheet organization information 352, playlist information 353, and untime information 354, and the program content data includes program basic information 361, program advertisements. This is data composed of information 362, program material information 363, and program metadata 364.

  In addition, the organization information DB 350 that primarily aggregates the organization data output from the broadcasting station 500 and the program information DB 360 that primarily aggregates the program content data output from the broadcasting station 500 are stored in the main storage unit 306. Each database (number DB 310, CMDB 320, main program DB 330) is configured.

  FIG. 6 is a diagram schematically showing a partial section of program frame organization information 351 and Q (Cue) sheet organization information 352 in “XX television”.

FIG. 7 is a diagram conceptually showing information stored in the composition information DB 350.
The program frame organization information 351 is information for specifying a broadcast time zone frame (program frame) of a broadcast program broadcast on “XXX TV”. Specifically, as shown in FIG. 7, it includes information on “program ID”, “station ID”, “broadcast date”, “program start time”, and “program frame time”, and is created for each TV program. It is a table. “Station ID” is an ID that identifies a broadcasting station, and “Program ID” is an ID that identifies a program.

  For example, in the program frame organization information 351, “XX News” is set in the frame from 19:00 to 20:00 on February 19, 2004, and the frame from 20:00 to 20:05 is set. It is assumed that “XX trip” is set. In addition, since a program frame of a broadcast program may change due to an extension of sports broadcast or emergency news, a plurality of program organization patterns are created in advance as the program frame organization information 351. Is used. Normally, about 20 types of program organization patterns are created, but in the first embodiment, as shown in FIG. 7, it is assumed that three types of program organization patterns 351a to 351c are created.

  The Q sheet organization information 352 is information for specifying a broadcast time frame of a broadcast program broadcast on “XX TV” by a level of CM or program advertisement time interval (set in seconds). Specifically, as shown in FIG. 7, the Q sheet organization information 352 is information associated with the “program ID” of the program frame organization information 351, and includes “material name”, “material ID”, and “material”. It is a table that includes information on “start time”, “material frame time”, “material type”, and “telop information”, and is created in units of seconds. The “material name” is a name of a material that is a component within the frame of the broadcast time zone. “Material ID” is an ID given to each material, “Material start time” is the start time of the frame of each material, and “Material frame time” is the time of the frame of each material. is there. In “Material Type”, “Confirm” is information indicating that “Material Frame Time” is fixed, and “Auto” is changed according to the change of “Material Frame Time” immediately before. “Untime” is information indicating that the “material frame time” is changed by the untime information 354. “Telop information” is information indicating the presence of character information that flows during a program broadcast.

  For example, as shown in FIG. 6 (2), “title”, “CM 1 to 5”, “main editions 1 and 2”, and “bansen (program advertisement) A to C” are included in the “XX news” frame. Are set, and “main part 1” and “local mission (broadcasting advertisement)” are set in the frame of “XX trip”. “Bansen A” is set in the frame of 19:02:15 to 19:02:30 on February 19, 2004 as a program advertisement for “XX Cooking Show”. “B” is set as a program promotion of “Drama XX” in the frame of 19:29:45 on February 19, 2004 to 19:30:00, and “Bansen C” It is assumed that the program advertisement of “Drama XX Samurai” is set in a frame of 19:59:30 on February 19, 2004 to 20:00:00. In addition, “XX cooking show” of “Bansen A” is a broadcast program broadcast from 20:00 to 21:00 on February 21, 2004. In addition, “CM1” is set as a frame of “XX mobile company” in the frame of 19:02:00 to 19:02:15 on February 19, 2004, and “CM2” As a CM of “XX Auto Company”, it was set in the frame of 19:29:00 to 19:29:15 on February 19, 2004, and “CM3” was set as a CM of “XX Electric Company” Suppose that it is set to the frame of 19:29:15 on February 19, 2004 to 19:29:45.

  The frequency of changing the composition of CM and Banban is overwhelmingly higher than that of the main part of the TV program, and there is a high possibility that it will be changed until the start of broadcasting. Also, in sports programs and news programs, manual material switching (untimed operation) is often performed with uncertain time including the main part. For this reason, since the Q sheet organization information 352 needs to be updated sequentially in real time in conjunction with the organization system of the broadcasting station 500, a plurality of material organization patterns are created in advance, like the program frame organization information 351. One of a plurality of material knitting patterns is used. Normally, about 20 material composition patterns are created. However, in the first embodiment, as shown in FIG. 7, the material composition pattern is associated with the program ID “DR042513” of “XX News”. Three patterns 352a to 352c are created.

  As shown in FIG. 7, the organization information DB 350 is a database configured by associating Q sheet organization information 352 with “program ID” of the program frame organization information 351. In the organization information DB 350, a plurality of program organization patterns are created in advance, similarly to the program frame organization information 351. Normally, about 20 types of program organization patterns are created, but in the first embodiment, 9 types of organization patterns 350a to 350i are created. The knitting pattern 350d is a knitting pattern obtained by delaying each frame of the knitting pattern 350a by 30 minutes.

  The playlist information 353 corresponds most to the change from the knitting patterns 350a to 350i when the broadcast time frame of a broadcast program, CM, program advertisement, etc. changes due to an extension of sports broadcast or emergency news. This is information for selecting a possible program pattern. Specifically, when the knitting pattern 350a is used, when the broadcast time frame of a broadcast program, CM, program advertisement, etc. changes due to an extension (for example, 30 minutes) of a sports broadcast broadcast program When the play list information 353 indicating that the organization pattern 350d is selected is input from the PlayList data server 506, the organization pattern 350d in which each frame is delayed by 30 minutes from the organization pattern 350a used immediately before the extension of the sports broadcast. Change to

  The untime information 354 is information for specifying the broadcast time of the time-indeterminate program material by manual switching. In the Q sheet organization information 352, “material frame” in which “untime” is set in the “material type” column. This is information for changing the “time”.

  For example, the broadcast time zone of “bansen A” (material name “XX cooking show”, material ID “BS045143”) set in the frame of 19:02:15 to 19:02:30 is 5 In the case of making a change that extends for 2 seconds, if an instruction for changing the extension for 5 seconds is manually input from any of the news report support system 502, the program production system 503, or the automatic program transmission device 507, the input device will receive the untime information. 354 is created, and the created untime information 354 is input to the real-time program information server 300, and the real-time program information server 300 changes the broadcast time zone of “No. A” to be extended by 5 seconds.

FIG. 8 is a diagram conceptually showing information stored in the program information DB 360.
The program basic information 361 is information including “program ID”, “program name”, “episode”, “EPG information”, and “video type”.

  “Episode” is an ID for specifying the number of stories (the XX story, etc.) in these programs in series programs and regular programs. “EPG information” is EPG information to be displayed on a digital television receiver defined by ARIB (Radio Industry Association) superimposed on television broadcast waves.

  The program advertisement information 362 is information including “program ID”, “program logo”, “banquet original”, “bansen photo”, and “bansen (material ID)”.

  The “program logo” is a logo mark representing a program, and is, for example, as shown in FIGS. 15 (2) and 16 (2). The “bansen manuscript” is a manuscript text for advertising the program. The “bansen photo” is a promotional photo of the program.

  The program material information 363 is information including “material ID”, “material name”, “material scale”, “audio mode”, and “angle of view”, and is a detailed item in the main part of the program shown in FIG. Or information specifying frame level items for commercials and program advertisements.

  The program metadata 364 is information including “in-material time”, “link destination”, “authentication”, and “link data”, and information for specifying a detailed item in the main part of the program shown in FIG. It is. For example, if the broadcast program is a drama, scenes in the drama in the main part of the program are specified at predetermined intervals, and each of them is set as an item such as “scene 1 of main part 1”, “scene 2 of main part 1”, and the like. This information is specified separately. In addition, if the program is a TV shop program, it is information for setting a predetermined item for each product introduced in the TV shop program in the main part of the program and specifying each product divided into the items.

  FIG. 9 is a diagram conceptually showing the number DB 310, the CMDB 320, and the program main part DB 330 stored in the main storage unit 306.

  As shown in FIG. 9, each of the numbering DB 310, the CMDB 320, and the main program DB 330 includes an organization information DB 350 that temporarily aggregates the organization data output from the broadcast station 500, and the program contents output from the broadcast station 500. It is composed of a program information DB 360 for temporarily collecting data. Information stored in the organization information DB 350 and the program information DB 360 is stored in each of the numbering DB 310, the CMDB 320, and the main program DB 330 in accordance with the contents of the material. Specifically, it is identified by the material ID. For example, “No. A” (material name “XX cooking show”, material ID “BS 045143”) shown in FIG. 6B is stored in the No. DB 310 because it is a program advertisement. Also, “CM1” shown in FIG. 6B (the material name “XX mobile company” and material ID “CM032715” in the Q sheet organization information 352 shown in FIG. 7) is a CM and is stored in the CMDB 320. Further, the “title” shown in FIG. 6B (the material name “XX News” and the material ID “TT042513” in the Q sheet organization information 352 shown in FIG. 7) is the title of the program, and is therefore stored in the main program DB 330. The Note that the “original program ID” of the program advertisement DB 310 is an ID for associating the program advertisement with the program associated with the program advertisement, whereby the program advertisement associated with the program advertisement can be associated with the program advertisement DB 310. The program information of the program related to the program advertisement can be extracted from the program.

  That is, the real-time program information server 300 aggregates various types of information output from the broadcasting station 500, and integrally associates the aggregated various types of information based on the program (event) ID and material ID. It is a server that updates in real time according to changes in

  In addition, the real-time program information server 300 stores the number DB 310, the CMDB 320, and the main program DB 330 for each of a plurality of regions, and based on the channel received from the mobile phone 200, the time, and the position information. It is a server that extracts program information from any one of the mission DB 310, the CMDB 320, and the main program DB 330. When the channel and the broadcasting station are unified in the area related to the program information providing system 1, the program information is extracted based on the channel and the time.

Next, the operation of the program information providing system 1 will be described.
FIG. 10 is a flowchart showing a program reservation operation in the program information providing system 1.

  In the first embodiment, when a viewer is watching a normal television program on the television receiver 100 using the remote control function of the mobile phone 200, the program is being broadcast on the television receiver 100. An operation for acquiring the program information from the mobile phone 200 will be described. Note that program information can be acquired in the same manner for broadcast information such as broadcast programs and CMs.

  In order for the viewer to watch the TV program, the TV receiver 100 is turned on using the remote control function of the mobile phone 200 (S101). In this case, the viewer may manually turn on the television receiver 100.

  Using the remote control function of the mobile phone 200, the viewer presses the channel selection key of the input unit 208 to select the channel of the television receiver 100 (S102). When the channel selection key of the input unit 208 is pressed, channel information related to the pressed channel selection key is transmitted from the infrared transmission unit 203 to the television receiver 100, and channel information related to the pressed channel selection key is stored in the RAM 205b. (S103). In the first embodiment, only the most recently pressed channel information is stored in the RAM 205b, but a predetermined number of channel selection history information may be stored in the RAM 205b.

  When the television receiver 100 receives channel information from the infrared transmission unit 203, the display of the television receiver 100 is switched based on the received channel information.

  A viewer who has selected a channel (for example, the X channel) with the mobile phone 200 receives a television broadcast of the television receiver 100 (for example, “XX News” shown in FIG. 6: 19:00 on February 19, 2004). When watching TV-20:00 broadcast), a program advertisement CM (for example, “Bansen A (“ XX Cooking Show ”)” shown in FIG. 6) that flowed during the television broadcast: February 19, 2004 Watching 19:02:15 to 19:02:30) and watching (or recording) the TV program of this program advertising CM (if interested), the viewer The program information acquisition key of the mobile phone 200 is pressed (S104). Note that if the channel using the mobile phone 200 has not been changed since the start of viewing of the television broadcast in the television receiver 100, it is necessary to press the channel selection key before pressing the program information acquisition key. There is.

  When the program information acquisition key is pressed, the most recently selected channel information (X channel) stored in the RAM 205b, program information acquisition request information for requesting program information acquisition, and the mobile phone stored in the RAM 205b 200 user ID and position information are transmitted from the mobile communication unit 202 to the real-time program information server 300 (S105). In this case, it may be transmitted on the Web or may be transmitted using electronic mail. However, it is necessary to use a communication means that makes this transmission time accurate.

  When the real-time program information server 300 receives the channel information, the program information acquisition request information, the user ID and position information of the mobile phone 200 (S106), the received channel information, the program information acquisition request information, and the user ID of the mobile phone 200 are received. The received time (for example, 19:02:25 on February 19, 2004) is stored in the RAM 303b in association with the position information (S107). Subsequently, the material ID is extracted from the database stored in the main storage unit 306 based on the reception time, channel information, and position information stored in the RAM 303b (S108). Specifically, a station ID (for example, XX TV) is extracted from the numbering DB 310, the CMDB 320, and the main program DB 330 shown in FIG. 9 based on the received channel information “X channel” and position information. A material ID “BS045143” (item 310a) corresponding to the extracted station ID and the reception time (19:02:25 on February 19, 2004) is extracted. That is, the broadcast material is specified from the database stored in the main storage unit 306 based on the reception time, channel information, and position information stored in the RAM 303b.

  Subsequently, the program information stored in the database of the main storage unit 306 in association with the extracted material ID is acquired by the real-time program information server 300 based on the user ID of the mobile phone 200 received in S106. It transmits to the requested mobile phone 200 (S109). Specifically, each item of information 310a shown in FIG. 9 is transmitted.

  Also, viewing information in which the extracted material ID, channel information, user ID of the mobile phone 200, position information, and reception time are associated is stored in the viewing log of the viewing log DB 340 (S109). The viewing log DB 340 aggregates audience rating data based on viewing information stored in the viewing log. Further, the program information transmitted to the mobile phone 200 is associated with the user ID of the mobile phone 200 and stored in the control log of the viewing log DB 340 (S109).

  When the mobile phone 200 receives the program information transmitted by the real-time program information server 300 (S110), the received program information is stored in the RAM 205b (S111), and image information such as a program logo included in the program information is displayed on the display 206. (S112). For example, together with the program logo, the channel, the broadcast start date and time (broadcast start time), and the broadcast end date and time (broadcast end time) are displayed on the display 206 so that the viewer can easily recognize visually.

  Subsequently, using the channel, broadcast start date / time, broadcast end date / time, and program ID included in the received program information, recording reservation information for recording the TV program related to the received program information with the PVR 110 is created. Then, the created recording reservation information is transmitted from the infrared transmission unit 203 to the PVR 110 (S113). When the PVR 110 receives the recording reservation information, the recording reservation is registered based on the received recording reservation information. If the received program information is not program information related to program promotion, the process proceeds to S102 after S112.

  Note that the ID of the PVR 110 is stored in the RAM 205b in advance, and in S105, the ID of the PVR 110 stored in the RAM 205b together with the channel information, the program information acquisition request information, the user ID of the mobile phone 200, and the position information are stored in the mobile communication. Recording information is transmitted from the unit 202 to the real-time program information server 300, and in S109, the program information is transmitted to the mobile phone 200 that has requested acquisition of the program information, and the PVR 110 based on the program information is reserved for recording. The real-time program information server 300 may transmit the created recording reservation information to the PVR 110 based on the ID of the PVR 110. In this case, the recording reservation operation from the mobile phone 200 to the PVR 110 may not be executed in S113. In this way, recording reservation of the PVR 110 can be easily performed even if there is no viewer who has the mobile phone 200 beside the PVR 110.

  Subsequently, the above operation is repeated (S102 to S113) while the viewer who has the mobile phone 200 is watching the television broadcast of the television receiver 100, and the remote control function of the mobile phone 200 is used to make the television receiver. When the power-off of 100 is instructed (S114), the process ends.

  When the real-time program information server 300 is requested to acquire program information from the mobile phone 200 via the Web, a time difference answer is executed without immediately sending an answer on the Web for the requested program information. The real time program information server 300 may transmit the program information to the mobile phone 200 by e-mail. Also, watch “XX News” (set to 19:00 to 20:00 on February 19, 2004) on TV receiver 100, and appear in each news in “XX News” The above-described control operation can be applied when acquiring detailed information about the incident to be performed. That is, by extracting a material ID that identifies each news item in “XX news” divided at predetermined intervals in the main part of the program, it appears in each news in the program metadata 364 shown in FIG. Get detailed information about each case (such as “link” and “file name” for each case). Further, the above-described control operation can be applied when a television shopping program is viewed on the television receiver 100 and detailed information about each product introduced in the television shopping program is acquired. In other words, by extracting the material ID for specifying the item set for each product introduced in the TV shop program in the main part of the program, detailed information about each product in the program metadata 364 shown in FIG. Acquire “link destination”, “file name”, etc.) related to the contents of each product. In addition, when the drama program is viewed on the television receiver 100 and detailed information or the like about a person or an object appearing in each scene in the program is acquired, the above control operation can be applied. That is, by extracting the material ID that identifies the item of each scene in the drama divided at predetermined intervals in the main part of the program, the people and objects appearing in each scene in the program metadata 364 shown in FIG. Detailed information (“link destination”, “file name”, etc. relating to people and things) is acquired.

  FIG. 11 is a flowchart showing the program reservation update operation in the program information providing system 1.

  The control unit 303 periodically monitors the number DB 310, the CMDB 320, and the main program DB 330 stored in the main storage unit 306, and monitors whether any database is updated (S201). . If there is an update in any of the databases, such as when the broadcast time frame for broadcast programs, commercials, program advertisements, etc. changes due to extended sports broadcasts or emergency news, etc. S201), the updated data is acquired from the updated database (S202).

  The acquired data is compared with the data before acquisition stored in the control log of the viewing log DB 340, and only the updated portion is extracted from the acquired data (S203).

  Subsequently, the extracted portion is transmitted as difference information to the mobile phone 200 stored in the control log in association with the portion extracted from the acquired data (S204). In addition, the extracted portion is updated with respect to the data before acquisition stored in the control log.

  The control unit 205 of the mobile phone 200 periodically monitors whether or not the difference information is received from the real-time program information server 300 (S205). If the difference information is received from the real-time program information server 300, it is stored in the RAM 205b. The program information related to the received difference information is updated in the program information being received (S206). Subsequently, the fact that the program information has been updated is displayed (S207).

  Specifically, image information such as a program logo included in the updated program information is displayed on the display 206 (S207). For example, along with the program logo and channel, the changed broadcast start date and time, and the changed broadcast end date and time, a message “The broadcasting time of“ XX cooking show ”has been changed” is displayed on the display 206 and viewed. Make it easier for a person to visually recognize changes.

  Subsequently, using the channel, the broadcast start date and time, the broadcast end date and time, and the program ID included in the updated program information, the recording reservation information for reserving the TV program related to the updated program information is created and created. The recording reservation information is transmitted from the infrared transmission unit 203 to the PVR 110 (S208). Along with this transmission, the recording reservation deletion information for deleting the recording reservation registered before the update is created based on the program ID, the created recording reservation deletion information is transmitted, and the recording reservation registered before the update is deleted. You may make it do. When the PVR 110 receives the recording reservation information, the recording reservation is registered based on the received recording reservation information.

  When the real-time program information server 300 transmits the recording reservation information to the PVR 110 in S109 shown in FIG. 10, the difference information is transmitted to the mobile phone 200 and the PVR 110 based on the updated program information is reserved for recording.

  The user ID of HDD recorder 600 is identification information for identifying HDD recorder 600 on the network, and is associated with an IP address, for example, and stored in RAM 606b.

Next, the operation of the program information providing system 3 will be described.
FIG. 22 is a flowchart showing a program reservation operation in the program information providing system 3.

  This operation is performed by the HDD recorder 600 using the remote controller 620 when the viewer is watching a normal television program on the television receiver 100, and the HDD recorder 600 displays program information relating to the program advertisement being broadcast on the television receiver 100. It is an action to get. Note that program information can be acquired in the same manner for broadcast information such as broadcast programs and CMs.

  In order for the viewer to watch the television program, the remote controller 620 is used to turn on the television receiver 100 and the HDD recorder 600 (S601). The power of the television receiver 100 or the HDD recorder 600 may be turned on without using the remote controller 620.

  Using the remote controller 620, the viewer presses the channel selection key of the remote controller 620 to select the channel of the television receiver 100 (S602). When the channel selection key of the remote control 620 is pressed, channel information regarding the pressed channel selection key is transmitted from the remote control 620 to the infrared communication unit 602. When the infrared communication unit 602 receives the channel information from the remote controller 620, the received channel information is stored in the RAM 606b (S603). That is, the channel information related to the broadcast information output to the television receiver 100 is stored in the RAM 606b. In this operation, only channel information related to broadcast information output to the television receiver 100 is stored in the RAM 606b, but a predetermined number of channel selection history information may be stored in the RAM 606b.

  When HDD recorder 600 receives channel information from remote controller 620, the display of television receiver 100 is switched based on the received channel information.

  A viewer who has selected a channel (for example, the X channel) with the remote controller 620 has a television broadcast (broadcast program) displayed on the television receiver 100 (for example, “XX News” shown in FIG. 6: February 2004). When watching TV from 19:00 to 20:00 on the 19th), a program advertisement CM (for example, “Bansen A (“ XX Cooking Show ”)” shown in FIG. 6) was broadcast during the TV broadcast. : 19:02:15 on February 19, 2004-19:02:30 Broadcasting) If you want to watch (or record) the TV program of this program advertisement (interested) The viewer presses the program information acquisition key of the remote controller 620 (S604).

  When the program information acquisition key is pressed, information indicating that the program information acquisition key has been pressed is transmitted from the remote control 620 to the infrared communication unit 602. When information indicating that the program information acquisition key has been pressed is received from the remote control 620 by the infrared communication unit 602, a request for program information acquisition is made together with channel information (X channel) relating to the broadcast information currently output to the television receiver 100. The program information acquisition request information to be transmitted and the user ID and position information of the HDD recorder 600 stored in the RAM 606b are transmitted from the communication unit 601 to the real-time program information server 300 (S605). In this case, it may be transmitted on the Web or may be transmitted using electronic mail. However, it is necessary to use a communication means that makes this transmission time accurate. When using a communication means whose transmission time is relatively delayed, the channel information, the program information acquisition request information, the user ID and position information of the HDD recorder 600, and time information related to the time when the program information acquisition key is pressed May be transmitted to the real-time program information server 300.

  When the real-time program information server 300 receives the channel information, the program information acquisition request information, the user ID and position information of the HDD recorder 600 (S606), the received channel information, the program information acquisition request information, and the user ID of the HDD recorder 600 are received. The received time (for example, 19:02:25 on February 19, 2004) is stored in the RAM 303b in association with the position information (S607). When the time information is received together with the channel information, the program information acquisition request information, the user ID of the HDD recorder 600 and the position information, the time related to the time information is stored in the RAM 303b as the reception time.

  Subsequently, the material ID is extracted from the database stored in the main storage unit 306 based on the reception time, channel information, and position information stored in the RAM 303b (S608). Specifically, a station ID (for example, XX TV) is extracted from the numbering DB 310, the CMDB 320, and the main program DB 330 shown in FIG. 9 based on the received channel information “X channel” and position information. A material ID “BS045143” (item 310a) corresponding to the extracted station ID and the reception time (19:02:25 on February 19, 2004) is extracted. That is, the broadcast material is specified from the database stored in the main storage unit 306 based on the reception time, channel information, and position information stored in the RAM 303b. If the channel and the broadcasting station are unified in the area related to the program information providing system 3, the material ID is extracted based on the received channel information and the reception time.

  Subsequently, the program information stored in the database of the main storage unit 306 in association with the extracted material ID is extracted, and the extracted program information is acquired based on the user ID of the HDD recorder 600 received in S606. The real-time program information server 300 transmits the requested HDD recorder 600 (S609). Specifically, each item of information 310a shown in FIG. 9 is transmitted. If the program information relates to program advertisement, information related to the broadcast program related to the program advertisement (program ID, program logo, channel, broadcast start date / time, broadcast end date / time, etc.) is extracted based on the “original program ID”. This information is included in the program information related to the program advertisement and transmitted.

  Also, viewing information in which the extracted material ID, channel information, user ID of the HDD recorder 600, position information, and reception time are associated is stored in the viewing log of the viewing log DB 340 (S609). The viewing log DB 340 aggregates audience rating data and the like based on viewing information stored in the viewing log. Further, the program information transmitted to the HDD recorder 600 and the user ID of the HDD recorder 600 are associated with each other and stored in the control log of the viewing log DB 340 (S609).

  When the HDD recorder 600 receives the program information transmitted by the real-time program information server 300 (S610), the received program information is stored in the recording unit 611 (S611), and image information such as a program logo included in the program information is stored. The image is output from the video output unit 608 to the television receiver 100 and displayed on the television receiver 100 (S612). For example, a program logo, a channel, a broadcast start date and time, and a broadcast end date and time are displayed on a part of the video currently broadcast on the television receiver 100, and the viewer can easily visually recognize the acquired program information. Like that. Note that image information such as a program logo may be displayed on the operation unit 610 or the display unit of the remote controller 620.

  Further, the link information included in the acquired program information may be displayed on the television receiver 100, and the displayed link information may be selected to access the website related to the link information.

  Subsequently, based on the material ID included in the received program information, it is determined whether or not the program information is program information related to program promotion (S613), and the received program information is the program information related to program promotion. If not, the process proceeds to S602. If the received program information is program information related to program promotion (S613), recording reservation information for recording the broadcast program related to the program promotion of the received program information by the recording unit 611 is included in this program information. Is created based on the channel, the broadcast start date and time, the broadcast end date and time, and the program ID, and the created recording reservation information is stored in the RAM 606b (S614).

  In S609, the program information is transmitted to the HDD recorder 600 that has requested acquisition of the program information, and if the program information is program information related to program promotion, the recording reservation information related to the program information is created and created. The real-time program information server 300 may transmit the recording reservation information to the HDD recorder 600.

  Subsequently, the above operation is repeated in a state where the viewer who has the remote controller 620 is watching the television broadcast displayed on the television receiver 100 (S602 to S614). When the power-off of HDD recorder 600 is instructed by operation from operation unit 610 or remote controller 620 (S615), the operation is terminated.

  After the above operation is completed, a list of program information stored in the recording unit 611 in S611 is displayed on the television receiver 100 by an operation from the operation unit 610 or the remote controller 620, and a desired program is displayed from the displayed list of program information. Information may be selected and displayed.

  When the real-time program information server 300 is requested to acquire program information from the HDD recorder 600 via the Web, a time difference answer is executed without immediately sending an answer on the Web for the requested program information. The program information may be transmitted from the real-time program information server 300 to the HDD recorder 600 by e-mail.

  When the program information transmitted to the HDD recorder 600 relates to program advertisement, the material ID related to the program information and the user ID of the HDD recorder 600 are stored in the viewing log DB 340 in association with each other, and the material ID (or the user) Based on the ID, the real-time program information server 1300 may aggregate or create various information related to recording reservations (recording reservation rate data, number of recording reservations, etc.).

FIG. 23 is a flowchart showing the program reservation updating operation in the program information providing system 3.
The control unit 303 periodically monitors the number DB 310, the CMDB 320, and the main program DB 330 stored in the main storage unit 306, and monitors whether there is an update in any database (S701). . If there is an update in one of the databases, such as when the broadcast time frame for broadcast programs, commercials, program advertisements, etc. changes due to extended sports broadcasts or emergency news, etc. S701), the updated data is acquired from the updated database (S702).

  The acquired data and the pre-acquisition data stored in the control log of the viewing log DB 340 are compared, and only difference information that is information related to the updated portion is extracted from the acquired data (S703).

  Subsequently, based on the user ID of the HDD recorder 600 stored in the control log in association with the program information including the program ID related to the extracted difference information as “original program ID”, this extracted portion is used as the difference information. The data is transmitted to the HDD recorder 600 (S704). Further, the program information related to the extracted difference information is updated for the pre-acquisition data stored in the control log.

  The control unit 606 of the HDD recorder 600 periodically monitors whether or not the difference information is received from the real-time program information server 300 (S605). If the difference information is received from the real-time program information server 300, the control unit 606 stores the difference information in the recording unit 611. Among the stored program information, the program information including the program ID related to the received difference information as the “original program ID” is updated (S706). Subsequently, the fact that the program information has been updated is displayed (S707).

  Specifically, when a television broadcast is displayed on the television receiver 100, image information such as a program logo included in the updated program information is output to the video output unit 608, and this image information is output to the television receiver. 100 is displayed (S707). For example, along with the program logo, channel, the changed broadcast start date and time, and the changed broadcast end date and time, a message “The broadcasting time of“ XX cooking show ”has been changed” is displayed on the television receiver 100. , Allowing viewers to easily recognize changes visually. Further, the message may be output by voice from the television receiver 100 and notified. If no television broadcast is displayed on the television receiver 100, image information such as a program logo included in the updated program information is displayed on the operation unit 610 or the display unit of the remote controller 620 (S707).

  Subsequently, the recording reservation information for recording the television program related to the updated program information in the recording unit 611 is based on the channel, the broadcast start date and time, the broadcast end date and time, and the program ID included in the updated program information. The created recording reservation information is stored in the RAM 606b (S620). Together with the operation of storing the recording reservation information in the RAM 606b, the recording reservation information related to the update stored in the RAM 606b before the update is deleted.

  When the real-time program information server 300 directly transmits the recording reservation information to the HDD recorder 600 in S609 shown in FIG. 22, the difference information is transmitted to the HDD recorder 600 and the HDD based on the updated program information is transmitted. Recording reservation information for making the recorder 600 make a recording reservation is created, and the real-time program information server 300 transmits the created recording reservation information to the HDD recorder 600. Simultaneously with this transmission, the recording reservation deletion information for deleting the recording reservation registered before the update is transmitted, and the recording reservation registered before the update is deleted.

FIG. 24 is a flowchart showing the reserved program viewing operation in the program information providing system 3.
This control operation is an operation performed when a viewer who uses the HDD recorder 600 views “OO cooking show” during an actual broadcast time zone.

  When the program information stored in the recording unit 611 relates to the program advertisement, based on this program information, a predetermined time (for example, 2 hours before) of the broadcast start time of “XX Cooking Show” included in the program information. It is determined whether or not the time has been reached (S801). If the predetermined time has been reached, a message indicating that the time is a predetermined time before the broadcast start time is displayed, and the viewer is notified of “ (S802) so that the broadcast can be seen. Specifically, when a television broadcast is displayed on the television receiver 100, the image logo included in the program information and “two hours before the broadcast start time of“ XX Cooking Show ”. “If you want to stop the notification of“ Cooking show ”, press the delete key.” Is output to the video output unit 608, and this image logo and message are displayed on the television receiver 100.

[Fourth Embodiment]
In the fourth embodiment of the present invention, program information is distributed to the HDD recorder 600 by a multicast method.
FIG. 26 is a flowchart showing a program reservation operation in the program information providing system 3 according to the fourth embodiment of the present invention.

  The control unit 303 extracts program information within a predetermined period (for example, for one week) from the program information stored in the main DB 306, CMDB 320, and main program DB 330 stored in the main storage unit 306. The multicast communication unit 301a executes IP multicast communication and distributes the program information within the predetermined period to the HDD recorder 600 by simultaneous broadcast transmission (S1001). In this case, the program information of the distributed area may be transmitted, and the real-time program information server 300 distributes the program information of all the areas, and the HDD recorder 600 that receives the distributed program information. It is also possible to extract program information related to the area where the device is installed and store the extracted program information in the recording unit 611. This distribution may be executed in response to a request from the HDD recorder 600.

  When the HDD recorder 600 receives the program information distributed by the real-time program information server 300, the received program information is stored in the recording unit 611 (S1005). For example, the program information for one week of the number DB 310, the CMDB 320, and the program production DB 330 shown in FIG. In this case, the fact that the program information has been received and the program information within a predetermined period (for example, the latest one hour) are output from the video output unit 608 to the television receiver 100, and these pieces of information are output to the television receiver 100. May be displayed.

  Subsequently, the control unit 303 periodically monitors the number DB 310, the CMDB 320, and the main program DB 330 stored in the main storage unit 306, and monitors whether any database is updated. (S1002). If there is an update in any of the databases, the updated data is acquired from the updated database, and only the difference information that is information related to the updated portion is extracted from the acquired data (S1003).

  Subsequently, the multicast communication unit 301a executes IP multicast communication, and distributes the extracted difference information to the HDD recorder 600 by simultaneous broadcast transmission (S1004).

  The control unit 606 of the HDD recorder 600 periodically monitors whether or not the difference information is received from the real-time program information server 300 (S1006), and if the difference information is received from the real-time program information server 300, the control unit 606 stores the difference information in the recording unit 611. In the stored program information, the portion related to the received difference information is updated (S1007).

  Subsequently, it is determined whether or not the updated portion relates to program information related to broadcast information that has already been reserved for recording (S1008), and the updated portion relates to program information related to broadcast information that has already been reserved for recording. If so, recording reservation information is created based on the channel included in the program information, the updated broadcast start date and time, and the updated broadcast end date and time, and stored in the RAM 606b (S1009). Along with this recording reservation, the recording reservation information related to the update stored in the RAM 606b before the update is deleted.

  Subsequently, the viewer presses the channel selection key to determine whether or not a channel has been selected (S1010). When the channel selection key is pressed, the television is set based on the channel information regarding the pressed channel selection key. The display of the receiver 100 is switched, and channel information related to the pressed channel selection key is stored in the RAM 606b (S1011). In the fourth embodiment, only the most recently pressed channel information is stored in the RAM 606b, but a predetermined number of channel selection history information may be stored in the RAM 606b.

  When a viewer who has selected a channel with the remote controller 620 is watching a television broadcast displayed on the television receiver 100, he / she sees a program advertisement CM that has flowed during the television broadcast, and sees a TV program (for example, a program advertisement CM). When it is desired to watch (or record) “XX cooking show”) (when interested), the viewer presses the program information acquisition key (S1012).

  When the program information acquisition key is pressed, the time when the program information acquisition key is pressed is stored in the RAM 606b in association with the channel information related to the broadcast information currently output to the television receiver 100 (S1013). Subsequently, the material ID is extracted from the program information stored in the recording unit 611 based on the pressing time and channel information stored in the RAM 606b (S1014). That is, the broadcast material is specified from the program information stored in the recording unit 611 based on the press time and channel information stored in the RAM 606b.

  Subsequently, the program information stored in the recording unit 611 in association with the extracted material ID is extracted, and image information such as a program logo included in the extracted program information is displayed on the television receiver 100 (S1015). For example, when the extracted program information relates to a program advertisement, the channel of the program, the broadcast start date and time, and the broadcast end date and time are displayed on the television receiver 100 together with the program logo so that the viewer can easily recognize visually. To. Subsequently, it is determined whether or not the extracted program information is the program information related to the program advertisement (S1016). If the extracted program information is the program information related to the program advertisement, the channel included in the program information is determined. The recording reservation information is created based on the broadcast start date and time and the broadcast end date and time, and the created recording reservation information is stored in the RAM 606b (S1017). Subsequently, the above operation is repeated while the viewer is watching the television broadcast of the television receiver 100 (S1006 to S1017).

  Note that each time an operation is performed on the operation unit 610 or the remote controller 620, operation information related to this operation is transmitted from the HDD recorder 600 to the real-time program information server 300, and when the real-time program information server 300 receives the operation information, the operation information is received. Operation information may be stored in the viewing log of the viewing log DB 340, and various data may be aggregated or created based on the stored operation information. The various data includes recording reservation total data, audience rating data, recording / playback data, and the like, and operation information includes channel information, recording reservation information, recording / playback information, and the like. For example, when channel information related to channel selection is received from the HDD recorder 600, the viewing log DB 340 correlates the material ID related to the channel information (or together with the position information) and the reception time with the user ID of the HDD recorder 600. Based on the material ID (or user ID), the real-time program information server 1300 creates or tabulates various types of information (viewing rate data, number of views) regarding the viewing rate.

  The program information received from the real-time program information server 300 may be transmitted from the HDD recorder 600 to the remote controller 620, and the program information may be displayed on the display unit of the remote controller 620. Further, the HDD recorder 600 may execute the control operations shown in FIGS.

  The program information displayed on the television receiver 100 is displayed, for example, as shown in FIGS. FIGS. 15 (1) and 16 (1) are examples in which three “Broadcasting station logo marks” are displayed. FIGS. 15 (2) and 16 (2) are “Program logo marks currently being broadcast”. 15 (3) and FIG. 16 (3) are examples in which one “image showing the contents of a program currently being broadcast” is displayed, and FIGS. 15 (4) to (5) are displayed. ) Is an example in which character information corresponding to the image display shown in FIGS. 15 (1) to (3) is displayed. 18 (2) to 18 (4) show twelve logo marks displayed on the television receiver 100. FIG. 19 (3) to 19 (5) show various logo marks displayed on the television receiver 100 shown in FIGS. 19 (1) and 19 (2) (FIGS. 18 (3) and (4)). FIG. 6 is a diagram illustrating an example of displaying various image information and the like stored in a recording unit 611 in association with various selected logo marks on the television receiver 100 when the viewer selects the image.

  As described above, by distributing the program information to the HDD recorder 600 by the multicast method, the program information currently being broadcast can be accurately acquired, and the accurate program information currently being broadcast can be displayed. Specifically, in the HDD recorder 600, the control unit 606 identifies the material ID of each channel related to the current time (or a time before the current time) based on the current time, and sets the identified material ID to the identified material ID. Image information such as a program logo mark included in the associated program information is extracted from the recording unit 611, and the extracted image information is sequentially displayed on the television receiver 100. One or more pieces of image information may be extracted. As a result, a broadcast station logo mark, a currently broadcast program logo mark, an image showing the contents of the currently broadcast program, a photograph of the currently broadcast program advertisement, and the like can be displayed on the television receiver 100. Also, as shown in FIGS. 16 (2), 18 (3), and 19 (1), an image for channel selection is displayed on the remote control for the “program logo mark” currently displayed on the television receiver 100. The channel may be selected by selecting with a key operation from 620. Also, the “broadcasting station logo mark” shown in FIGS. 16 (1) and 18 (2) and “the contents of the program currently being broadcast” shown in FIGS. 16 (3), 18 (4), and 19 (2). The operation for “showing image” is the same. In this case, since the contents currently being broadcast can be easily recognized visually, it is possible to realize a fun and easy-to-understand remote control operation for channel selection. Further, when selecting a channel, it is possible to visually recognize the contents of the program currently being broadcast for the channel to be selected next, so that unnecessary channel selection operations can be suppressed.

  Also, watch “XX News” (set to 19:00 to 20:00 on February 19, 2004) on TV receiver 100, and appear in each news in “XX News” The above-described control operation can be applied when acquiring detailed information about the incident to be performed. For example, the broadcast time slot of “main part 1” shown in FIG. 6 (2) is detailed in the items taken up in “main part 1” (such as news of a XX trial, a result of a professional baseball game, etc.). The broadcast material is divided into broadcast materials, and a material ID and various information related thereto are assigned to the broadcast material and stored in the main program DB 330. Then, by extracting the program information related to the material ID that identifies each news item in the “XX news” divided for each item in the main part of the program, each news in the program metadata 364 shown in FIG. Get detailed information about each incident that appears in (such as “link” and “file name” for each incident).

  Further, the above-described control operation can be applied when a television shopping program is viewed on the television receiver 100 and detailed information about each product introduced in the television shopping program is acquired. For example, in the same manner as described above, the broadcast time frame of “TV shopping program” is the item taken up in “TV shopping program” (introduction of product “XX TV”, product “XX video recorder”, product The broadcast material is divided into broadcast materials set for each product (such as introduction of “XX accessories”), and a material ID and various information related thereto are assigned to the broadcast material and stored in the main program DB 330. Then, by extracting the program information related to the material ID that identifies the item set for each product introduced in the TV shop program in the main part of the program, each product in the program metadata 364 shown in FIG. Detailed information (such as “link destination” and “file name” related to the contents of each product) is acquired.

  In addition, when the drama program is viewed on the television receiver 100 and detailed information or the like about a person or an object appearing in each scene in the program is acquired, the above control operation can be applied. For example, in the same way as above, the broadcast time frame of “Drama XX Criminal” is the item taken up in “Drama XX Criminal” (“Action Scene”, “Arrest Scene”, “Mystery Scene” etc. As described above, the broadcast material is divided into broadcast materials for each predetermined scene in the drama, and a material ID and various information related thereto are assigned to the broadcast material and stored in the main program DB 330. Then, by extracting the program information relating to the material ID that identifies the item of each scene in the drama divided at predetermined intervals in the main part of the program, it appears in each scene in the program metadata 364 shown in FIG. Get detailed information about people and things (such as “link destination” and “file name” related to people and things).

  In addition, as shown in FIGS. 19 (3) to (5), each product or photo associated with a material ID for identifying each product introduced in a TV program or an item set for each scene is displayed. can do. Further, program information including link information related to the material ID can be easily viewed on the television receiver 100. Therefore, it is easy to access from the HDD recorder 600 to various types of link information being broadcast on the television receiver 100.

  Also, by distributing program information by the multicast method, information on CMs currently broadcast on the HDD recorder 600, TV shop program contact information and product information, and other information linked to broadcast programs are transmitted to the television receiver 100. Can be displayed.

  As shown in FIG. 17, when the program link information 1705a is accessed by the conventional program information acquisition method, the program site 1701 is first connected, and after a few steps (1702a to 1705a), the desired program site 1705a is accessed. To do. On the other hand, in each of the above embodiments, as shown in FIG. 9, link information related to each product in association with a material ID that specifies an item set for each product introduced in the TV shop program. Are stored, and the HDD recorder 600 can easily acquire program information including link information related to each product. Therefore, when the HDD recorder 600 accesses the link information 1704d of the CM being broadcast on the television receiver 100 and the link information 1705a to c of the product of the TV shop program, it is included in the program information acquired by the HDD recorder 600. Link information (e.g., 1705a-d) can be directly accessed. That is, it is easy to access from the HDD recorder 600 the link information 1704d of the CM being broadcast on the television receiver 100 and the link information 1705a to 1c of the product of the TV shop program.

  In addition, about each operation | movement shown to S1001-S1007 and S1010-S1015 shown in FIG. 26, such as a digital television receiver etc. which have a communication function which communicates between the real-time program information servers 300, and the memory | storage part which stores program information. It can be applied to a video viewing device. In addition, each operation can be applied to an information processing apparatus such as a personal computer having a communication function for communicating between a tuner of a digital television and the real-time program information server 300 and a recording function. Each operation can also be applied to analog broadcasting.

[Fifth Embodiment]
FIG. 27 is a diagram conceptually showing the numbering DB 1310, the CMDB 1320, and the main program DB 1330 stored in the main storage unit 1306 of the real-time program information server 1300 according to the fifth embodiment.

  As in the fourth embodiment, the fifth embodiment of the present invention distributes program information from the real-time program information server 1300 to the HDD recorder 600 by a multicast method, and distributes difference information and the like related to the update. As shown in FIG. 27, various information is added to the main storage unit 306 of the real-time program information server 300. The various information is, for example, CM skip NG information, channel selection screen information, video content ID, replacement ID, viewing valid period information (use valid period information, right valid period information), and basic program information shown in FIG. 361 or information included in the program metadata 364.

  Also, a recording instruction key used when recording broadcast information currently being broadcast, a skip instruction key used when skipping a broadcast frame such as a CM flowing during the recorded broadcast, and a desired video content are selected. A video content selection key used in this case is provided on the operation unit 610 and the remote controller 620.

  The real-time program information server 1300 is the same as the real-time program information server 300 except for the main storage unit 1306 that stores the number DB 1310, the CMDB 1320, and the main program DB 1330, and the operation unit 610 and the remote controller 620.

FIG. 28 is a flowchart showing a channel selection screen display control operation in the program information providing system 5 according to the fifth embodiment of the present invention.
FIG. 29 and FIG. 36 are diagrams showing display examples of a broadcast station logo mark, a program logo mark currently being broadcast, an image showing the contents of the currently broadcast program, etc. displayed on the television receiver 100.

  This control operation is an operation for controlling the arrangement and size of a program logo mark or the like currently displayed on the television receiver 100 based on information from the broadcasting station. As in the fourth embodiment, the HDD recorder 600 acquires program information from the real-time program information server 1300 and stores the acquired program information in the recording unit 611.

  When an instruction to turn on the channel selection screen display is given, the operation starts. In the HDD recorder 600, the material ID of each channel related to the current time (or a time before a predetermined time before the current time) is extracted from the program information stored in the recording unit 611 based on the current time ( S1101), it is determined whether or not the “channel selection screen information” is included in the program information related to the extracted material ID of each channel (S1102). If the “channel selection screen information” is not included in the program information related to the extracted material ID of each channel (S1102), image information such as a program logo mark included in the program information related to the extracted material ID of each channel is displayed. Taking out from the recording unit 611 (S1105), as shown in FIGS. 29 (1) to (3), the taken image information is displayed on the television receiver 100 (S1106). The image information to be displayed on the television receiver 100 includes a broadcast station logo mark, a program logo mark currently being broadcast, an image showing the contents of a program currently being broadcast, a photograph of a program advertisement currently being broadcast, a visual EPG, and the like. In addition, when the video currently being broadcast is displayed on the television receiver 100, the image information may be displayed on a part of the video currently being broadcast.

  On the other hand, if “program selection screen information” is included in the program information related to the material ID of each extracted channel (S1102), an image such as a program logo mark included in the program information related to the extracted material ID of each channel Information is extracted from the recording unit 611 (S1103), and the extracted image information is displayed on the television receiver 100 as shown in FIGS. 29 (4) to (6) in accordance with the information of the “channel selection screen information” (S1103). ). For example, when displaying the image information related to the material ID to which “4 times / upper left” is added to the information of “channel selection screen information”, “○ tele” shown in the upper left of the screen in FIG. In this way, the image related to “○ tele” is displayed at the upper left of the screen in a size four times the normal size. In this case, the image information such as the program logo mark related to the program information not including the “channel selection screen information” is compared with the image including the “channel selection screen information” as shown in FIG. Small, display in normal order or ordered. In addition, as shown in FIG. 36 (1), according to the information of “channel selection screen information”, image information such as a program logo mark included in program information for a predetermined time (for example, 24 hours) related to one broadcasting station. Certain of them may be arranged on a circle. As shown in FIG. 36 (2), the horizontal axis is a channel axis and the vertical axis is a time axis, according to the information of “channel selection screen information”. The image relating to the predetermined channel may be arranged in the middle of the screen. Further, another display form based on the information of “channel selection screen information” may be executed. The extracted image information may be displayed on the display unit of the operation unit 610 or the remote controller 620.

  Subsequently, it is determined whether or not an instruction to turn off the channel selection screen display has been issued (S1107). If an instruction to turn OFF is given, the operation is terminated. On the other hand, if the OFF instruction is not given, the operations of S1101 to S1106 are repeatedly executed.

  In this way, by performing the channel selection screen display control operation, the viewer side is not based on the conventional channel number order display or display according to the viewer's preference, but based on the information on the broadcast station side. The display on the screen can be controlled. For example, when a broadcasting station broadcasts a new program, a program logo mark of the program, a photograph of a performer, etc. can be displayed larger than the display of other broadcasting stations in a prominent position in the middle or upper left. . For this reason, it is possible to make the new program visually recognizable to the viewer who has seen this display, so that the desire to view the new program is efficiently increased and linked to the viewing of the new program. be able to. In addition, in the case of advertising of products, etc., as well as when promoting programs, it is possible to make it easy to visually recognize CMs and numbers, as described above. Can be increased.

  In order to allow viewers to use this operation, it is conceivable that the broadcast station distributes program information for free. The channel selection screen information can be applied to the mobile phone 200 according to the second embodiment.

FIG. 30 is a flowchart showing a program recording operation in the program information providing system 5.
This control operation is a recording operation that indicates a case in which recording is instructed by a viewer's operation in HDD recorder 600 and a case in which a television program for which recording has been reserved is recorded. For example, a case where “XX News” broadcast from 19:00 to 20:00 on February 19, 2004 is recorded will be described.

  It is determined whether or not recording of the currently broadcast television broadcast is instructed by an operation from the remote controller 620 (S1201). If recording of the currently broadcast television broadcast is not instructed, the recording reservation information stored in the RAM 606b is determined. Based on the above, it is determined whether or not the broadcast start time of “XX News” (19:00 on February 19, 2004) has come (S1202).

  If there is no recording instruction for the currently broadcast television broadcast (S1201) and the broadcast start time of the recording reservation has not been reached (S1202), the system waits until the recording instruction or the broadcast start time.

  When an instruction from the remote controller 620 is given to record a television broadcast that is currently being broadcast (S1201), or when the broadcast start time of “XX News” is reached (S1202), the current time and recording are instructed. Based on the channel information related to the TV broadcast channel (channel related to the recording reservation), the material ID related to the current time and the channel information is extracted from the program information stored in the recording unit 611 (S1203).

  Subsequently, the broadcast information received from the broadcast station 500 is associated with various information included in the program information stored in the recording unit 611 in association with the extracted material ID, and is recorded in the recording unit 611 (S1204). For example, as shown in FIG. 27, the various information includes a material ID, CM skip NG information, video content ID, replacement ID, and viewing validity period information.

  It is determined whether or not the end of recording has been instructed by an operation from the remote controller 620 (S1205). If the end of recording has not been instructed, the “xxx news” is stored based on the recording reservation information stored in the RAM 606b. It is determined whether or not the broadcast end time (20:00 on February 19, 2004) has come (S1206).

  If the end of recording is not instructed by the operation from the remote controller 620 (S1205), and if the broadcast end time of “XX News” has not been reached (S1206), the operations of S1203 and S1204 are repeated.

  When the end of recording is instructed by an operation from the remote controller 620 (S1205) or when the broadcast end time of “XX News” is reached (S1206), the recording operation is ended.

FIG. 31 is a flowchart showing a recording / playback operation in the program information providing system 5.
This control operation is an operation in the case where a skip of CM or the like is instructed while the broadcast information recorded by the HDD recorder 600 is being reproduced. For example, the case where “XX news” broadcast from 19:00 to 20:00 on February 19, 2004 is recorded and this “XX news” is reproduced will be described.

  When viewing of “XX news” recorded on HDD recorder 600 is instructed from remote controller 620 (S1301), “XX news” recorded in recording unit 611 is based on the program ID of “XX news”. The searched “XX news” is reproduced and displayed on the television receiver 100 (S1302). When “XX News” is displayed on the television receiver 100, it is monitored whether or not the skip instruction key of the remote controller 620 is pressed (S1303). The CM skip NG information recorded in the recording unit 611 corresponding to the broadcast information reproduced at the time of pressing is referred to (S1304).

  If “NG” is assigned to the CM skip NG information (S1304), “Operation is invalid (this scene cannot be skipped)” is displayed on the display unit of the remote controller 620, and this “NG” is stored. The reproduction is continued without skipping the reproduction of the broadcast information related to the broadcast material (S1305). You may make it display the notification to the effect that the said skip cannot be performed on the television receiver 100. FIG. On the other hand, if “OK” is added to the CM skip NG information, the reproduction of the broadcast information related to the broadcast material in which this “OK” is stored is skipped (S1306). Note that the broadcast information may be fast-forwarded and played instead of skipping.

  Specifically, when playback is started (S1302), as shown in FIG. 6 (2), “Title” is displayed for 2 minutes, followed by “CM1 (CM of“ XX Mobile Company ”)”. The If “CM1” is displayed and the viewer wants to skip (fast forward) “CM1”, he / she presses the skip instruction key on the remote controller 620 (S1303). In this case, since “NG” is added to the CM skip NG information of “CM1” (S1304), “Operation is invalid (this scene cannot be skipped)” is displayed on the display unit of the remote control 620. , “CM1” cannot be skipped (S1305).

  On the other hand, when “No. A” to be played back immediately after “CM 1” is displayed, if the viewer wants to skip (fast forward) “No. A”, he / she presses the skip instruction key on the remote controller 620 ( S1303). In this case, since “OK” is added to the CM skip NG information of “No. A” (S1304), “CM2” is skipped (S1306), and “main part 1” relating to the next broadcast material is stored. Is displayed.

  Subsequently, it is determined whether or not the end of reproduction is instructed (S1307). When the end of reproduction is instructed, the reproduction operation is terminated. On the other hand, if the end of reproduction is not instructed, the reproduction operation is continued (S1303 to S1306).

  Note that when the skip instruction key is pressed while displaying broadcast information related to the broadcast material with “NG” added to the CM skip NG information, instead of invalidating this operation, the broadcast related to the broadcast material is broadcast. Information playback may be skipped, broadcast information related to the broadcast material may be taken into the RAM 606b, and the fetched broadcast information may be displayed on a part of the video being played back by the television receiver 100. Alternatively, various image information included in the program information related to the broadcast material may be extracted from the recording unit 611, and the extracted various image information may be displayed on a part of the video being reproduced for a predetermined time.

  In this way, skipping during playback of predetermined broadcast information is disabled (displayed as part of a video, related images are displayed, etc.), so that the recorded broadcast information is being played and CMs, program advertisements, etc. Information can be surely viewed by the viewer. In other words, as there is a large-capacity recording / playback device and the time for viewing recorded broadcast information is increasing, a lot of information on CMs, program advertisements, etc., as in the case of viewing during broadcast hours. Viewers can be surely viewed, and advertising efficiency can be improved.

FIG. 32 is a flowchart showing a recording / playback operation in the program information providing system 5.
This control operation is an operation of skipping broadcast information such as CMs for which the viewing valid period has elapsed in the HDD recorder 600 during playback. For example, when recording “XX News” broadcast from 19:00 to 20:00 on February 19, 2004 and playing this “XX News” on October 6, 2004 Will be described.

  The operations in S1301 and S1302 are the same as the operations described above. When “xxx news” recorded on the HDD recorder 600 is displayed on the television receiver 100, the viewing effective period information recorded in the recording unit 611 corresponding to the broadcast information being reproduced is referred to. Then, it is determined whether the viewing valid period has elapsed for the broadcast information being reproduced (S1311). Specifically, if a value smaller than “20041006 (playback date and time)” is given to the viewing effective period information, it is determined that the viewing effective period has passed, and a numerical value equal to or greater than “20041006” is included in the viewing effective period information. If it is given, it is determined that it is within the viewing valid period. For example, since “20043030” is assigned to “CM1”, it is determined that the viewing valid period has elapsed.

  If the viewing effective period has elapsed (S1311), the broadcast information related to the broadcast material for which the viewing effective period has elapsed is skipped (S1312). On the other hand, if the viewing valid period has not elapsed (S1311), the reproduction of the broadcast information is continued (S1313). For example, “main part 1” is not given viewing effective period information, and the reproduction of broadcast information is continued.

  Subsequently, it is determined whether or not the end of reproduction is instructed (S1314). When the end of reproduction is instructed, the reproduction operation is terminated. On the other hand, if the end of reproduction is not instructed, the reproduction operation is continued (S1311 to S1313).

  In S1311, the broadcast information related to the broadcast material immediately before the broadcast material related to the currently reproduced broadcast information may be determined as to whether or not the viewing valid period has elapsed, and the operations of S1311 to S1313 may be performed. Further, before S1311, it is determined based on the material ID whether the broadcast information currently being reproduced is broadcast information related to CM or program advertisement, and the broadcast information currently being reproduced relates to CM or program advertisement. In such a case, the operations of S1311 to S1313 may be performed.

  In this way, by skipping broadcast information for which the viewing valid period has passed during playback, a CM related to a product with a limited sales period is broadcast, and when the sales period of this product ends, or a broadcast program related to program advertisement In such a case, since it is possible to allow viewers to view only the information that the viewer wants to view without giving extra information to the viewer, the efficiency of advertisement and promotion can be improved.

FIG. 33 is a flowchart showing a recording / playback operation in the program information providing system 5.
This control operation is an operation of replacing broadcast information such as CMs for which the viewing valid period has passed in the HDD recorder 600 with other broadcast information during reproduction. For example, when recording “XX News” broadcast from 19:00 to 20:00 on February 19, 2004 and playing this “XX News” on October 6, 2004 Will be described.

  Information for replacement with broadcast information for which the viewing valid period has passed (replacement information) is periodically or irregularly distributed from the real-time program information server 1300 to the HDD recorder 600. When the HDD recorder 600 receives the delivered replacement information, the received replacement information is stored in the recording unit 611. The replacement information is assigned the same replacement ID as the broadcast information to be replaced. Alternatively, the viewing valid period information may be added to the replacement information, and the HDD recorder 600 may sequentially delete the replacement information after the viewing valid period has elapsed. A signal related to the replacement information is superimposed on the video signal and the audio signal transmitted from the predetermined broadcasting station to the HDD recorder 600, and the replacement information is distributed from the predetermined broadcasting station to the HDD recorder 600 regularly or irregularly. You may do it.

  The operations in S1301, S1302, and S1311 are the same as the operations described above. When the reproduction of “XX News” recorded on the HDD recorder 600 is displayed on the television receiver 100, it is determined whether or not the viewing valid period of the broadcast information being reproduced has passed (S1311). If the viewing effective period has elapsed, the replacement unit provided with the same replacement ID as the replacement ID assigned to the broadcast information for which the viewing effective period has elapsed is searched from the recording unit 611 (S1321). For example, as shown in FIG. 27, since “20043030” is assigned to “CM1”, it is determined that the viewing valid period has passed, and is the same as the replacement ID “KS005” assigned to “CM1”. The recording unit 611 is searched for replacement information to which the replacement ID “KS005” is assigned.

  Subsequently, instead of reproducing the broadcast information whose viewing valid period has elapsed, the searched replacement information is output and displayed on the television receiver 100 (S1322). On the other hand, if the viewing valid period has not elapsed (S1311), the reproduction of the broadcast information is continued (S1323). If the viewing valid period has passed but no replacement information exists in the recording unit 611, the broadcast information is skipped or reproduced as it is.

  Subsequently, it is determined whether or not the end of reproduction is instructed (S1324), and when the end of reproduction is instructed, the reproduction operation is terminated. On the other hand, if the end of the reproduction is not instructed, the reproduction operation is continued (S1311, S1321 to S1323).

  In S1311, it may be determined whether or not the viewing valid period has elapsed for the broadcast information related to the broadcast material immediately before the broadcast material related to the currently reproduced broadcast information, and the operations of S1321 to S1323 may be performed. Further, before S1311, it is determined based on the material ID whether the broadcast information currently being reproduced is broadcast information related to CM or program advertisement, and the broadcast information currently being reproduced relates to CM or program advertisement. In this case, the operations of S1311, S1321 to S1323 may be performed.

  Also, based on the material ID, it is determined whether or not the broadcast information being currently reproduced is broadcast information related to CM or program advertisement. If the currently reproduced broadcast information relates to CM or program advertisement, the broadcast information The viewing / listening flag is recorded in the recording unit 611 in correspondence with the information. When the broadcast information is reproduced, in S1311, the presence or absence of a viewed flag is determined for the currently reproduced broadcast information, and the operations of S1321 to S1323 may be performed based on the presence or absence of the viewed flag. . That is, when the broadcast information is reproduced after the second time, since the broadcast information has a viewing-and-listening flag, replacement information is output instead of the broadcast information.

  In this way, when the playback of the same broadcast program is repeated twice or more, different CMs and program advertisements can be provided to the viewer in the same broadcast frame for each playback. Can raise the interest of the person. That is, the efficiency of advertisement and promotion can be increased. Also, instead of the viewing-and-listening flag, information on the number of times of reproduction (two-time reproduction, three-time reproduction, etc.) is given to the recorded broadcast information, and the replacement information that details the contents of the CM etc. according to the number of times of reproduction May be output. That is, the advertiser can acquire the right of the playback frame and can effectively use the playback frame.

  Further, when the replacement information is replacement information related to program advertisement, recording reservation information of the broadcast program channel, the broadcast start date and time, and the broadcast end date and time related to the replacement information is included in the replacement information, and the fourth embodiment is used. The reserved recording operation shown may be executed during playback. Further, various image information related to the broadcast program related to the replacement information may be included in the replacement information, and such information may be displayed when the program information acquisition key is pressed during reproduction. Also, in the case where the replacement information relates to a broadcast material other than the program advertisement, various information related to the replacement information may be acquired.

  Thus, by replacing broadcast information whose valid viewing period has passed with replacement information during playback, for example, when a CM related to a product with a limited sales period is broadcast and the sales period of this product ends, the same The CM of the latest product of the advertiser can be provided to the viewer. In addition, when a broadcast program related to program promotion ends, the latest information on the same broadcast program can be provided to the viewer. That is, for the provider, the opportunities for advertisement and advertisement increase, and the efficiency of advertisement and advertisement can be further enhanced. Moreover, since the viewer can always receive the latest information during recording / playback, it is efficient.

FIG. 34 (1) is a flowchart showing a recording operation in the program information providing system 5.
This control operation is an operation of recording broadcast information related to each broadcast material related to the specific scene, performer, contents, shooting location, etc. desired by the viewer in the HDD recorder 600.

  Assume that the video content ID relating to the actor “Oda ○ O” is “MD01”, and “Oda O O” appears in “Main story 1”, “CM 1”, and “Bansen A” shown in FIG. Note that a large number of video content IDs relating to specific scenes, performers, contents, shooting locations, etc. related to the broadcast material are assigned to the broadcast material. Specific scenes are “impressive scenes”, “appearance scenes of performers”, and “comic scenes” in dramas, etc. The performers are those who appear in news programs, variety programs, dramas, commercials, etc. , “Baseball”, “English conversation”, “cooking” and the like, and the shooting location indicates the location where the broadcast program such as “Shibuya” and “Ginza” is shot. The video content ID is identification information associated with each element and identifying each element.

  The recording unit 611 of the HDD recorder 600 stores keywords such as specific scenes, performers, contents, and shooting locations, and video content IDs in association with each other. These pieces of information may be delivered from the real-time program information server 1300 to the HDD recorder 600 regularly or irregularly, or only information relating to the change or addition may be delivered.

  When the video content selection key is pressed on the remote controller 620 (S1401), keywords such as a specific scene, performers, contents, and shooting location stored in the recording unit 611 of the HDD recorder 600 are displayed on the television receiver 100. (S1402). In this case, it may be displayed for each category, or may be displayed in order from the keyword with the highest frequency according to the selected frequency. Further, the display is switched according to an operation from the operation unit 610 or the remote controller 620. For example, in the performer category, the actor “* da * m”, the actor “× kawa × 1”, the caster “* yama * 2”, the baseball player “x valley × 3”, and the like are displayed. By operating the operation unit of the remote controller 620, for example, the actor “Oda ○ O” is selected from the performers displayed on the television receiver 100 and determined (S1403). Note that a keyword may be input from the operation unit 610 or the remote controller 620 and determined based on the keyword.

  Subsequently, the video content ID stored in the recording unit 611 is extracted in association with the determined “* da ○ male”, and the program information stored in the recording unit 611 is extracted based on the extracted video content ID. Then, the material ID to which this video content ID is assigned is extracted (S1404), recording reservation information is created based on the channel related to the extracted material ID, the broadcast start date and time, and the broadcast end date and time. Information is stored in the RAM 606b (S1405). Subsequently, in the program information stored in the recording unit 611, it is determined whether or not there is another material ID to which the video content ID related to “Oda ○ O” exists (S1406). If there is no material ID to which the video content ID related to “Oda ○ O” is assigned, the operation is terminated. If there is another material ID to which the video content ID related to “* da * m” is assigned (S1406), the operations of S1404 and S1405 are executed. That is, a recording reservation is made for broadcast information related to “main part 1”, “CM1”, and “No. A” shown in FIG.

A plurality of keywords may be selected (S1403), as in the case where “Oda ○ O” is selected as the performer and “impressed scene” is selected as the specific scene. In this case, in step S <b> 1404, the material ID to which the video content ID related to “Emotional scene” is added together with the video content ID related to “* da ○ male” is extracted.
By recording in this manner, it is possible to make a reservation for recording broadcast information according to the viewer's preference at the material level (program advertisement, CM, etc.). For this reason, it is possible to increase the possibility of the viewer watching the recording, and to dramatically increase the efficiency of advertisement and program promotion.

FIG. 34 (2) is a flowchart showing the recording / reproducing operation in the program information providing system 5.
This control operation is an operation of reproducing broadcast information related to each broadcast material related to the specific scene, performer, contents, shooting location, etc. desired by the viewer in the HDD recorder 600.

  The operation of operating the operation unit of the remote controller 620 to select and determine a desired keyword from the keywords displayed on the television receiver 100 is the same as S1401 to S1403 described above.

  Subsequently, the video content ID stored in the recording unit 611 is extracted in association with the determined “* da ○ male”, and the recorded broadcast stored in the recording unit 611 is extracted based on the extracted video content ID. Broadcast information associated with the video content ID is extracted from the information (S1414), and the extracted broadcast information is displayed on the television receiver 100 (S1415). Subsequently, in the broadcast information stored in the recording unit 611, it is determined whether or not there is other broadcast information associated with the video content ID related to “Oda ○ O” (S1416). If there is no other broadcast information associated with the video content ID related to “Ota ○ O”, the operation ends. If there is other broadcast information associated with the video content ID related to “* da * m” (S1416), the operations of S1414 and S1415 are executed.

  A plurality of keywords may be selected (S1403), as in the case where “Oda ○ O” is selected as the performer and “impressed scene” is selected as the specific scene. In this case, in S1414, broadcast information in which the video content ID related to “impressive scene” is associated with the video content ID related to “Oda ○ O” is extracted.

  By reproducing in this way, broadcast information according to the viewer's preference can be reproduced from the recorded broadcast information at the material level (program advertisement, CM, etc.). For this reason, the viewer can view only broadcast information of high interest. In addition, since the viewer's interest in the broadcast information can be increased, the efficiency of advertisement and program promotion can be dramatically increased.

FIG. 35 is a flowchart showing the broadcast information display control operation in the program information providing system 5.
This control operation is an operation for displaying broadcast information or program information related to each broadcast material related to the specific scene, performer, contents, shooting location, etc. desired by the viewer in the HDD recorder 600. .

  The operation of selecting and determining a desired keyword from the keywords displayed on the television receiver 100 by operating the operation unit of the remote controller 620 is the same as S1401 to S1403 described above.

  Subsequently, the video content ID stored in the recording unit 611 is extracted in association with the determined “* da ○ male”, and the program information stored in the recording unit 611 is extracted based on the extracted video content ID. Then, the material ID to which this video content ID is assigned is extracted (S1424), and included in the program information related to the extracted material ID based on the channel related to the extracted material ID, the broadcast start date and time, and the broadcast end date and time. Display reservation information for displaying various images to be displayed on the television receiver 100 is created, and the created display reservation information is stored in the RAM 606b (S1425). Subsequently, in the program information stored in the recording unit 611, it is determined whether or not there is another material ID to which the video content ID related to “Oda ○ O” exists (S1426). If there is another material ID to which the video content ID related to “Oh * O” is present (S1426), the operations of S1424 to S1426 are executed.

  If there is no material ID to which the video content ID related to “Oda ○ O” is assigned (S1426), it is determined whether or not the broadcast start time related to the display reservation information stored in the RAM 606b has been reached (S1427). ) If the broadcast start time related to the display reservation information stored in the RAM 606b has been reached, various images included in the program information related to the display reservation information are extracted from the program information stored in the recording unit 611. (S1428), along with the various extracted images, a message “Currently“ Oda ”is appearing on the XX channel” is displayed on a part of the video displayed on the television receiver 100 (S1429). . Subsequently, it is determined whether or not the power of the HDD recorder 600 is turned off (S1430). If the power of the HDD recorder 600 is turned off, the operation is terminated. If the HDD recorder 600 is not turned off (S1430), the operations of S1401 to S1403 and S1424 to S1429 are repeated.

  Note that when the broadcast start time related to the display reservation information stored in the RAM 606b is reached, instead of extracting various images and displaying the extracted various images and messages on the television receiver 100 in S1428 and S1429. The broadcast information related to the display reservation information may be displayed on a part or all of the video displayed on the television receiver 100 using the channel related to the display reservation information.

  A plurality of keywords may be selected (S1403), as in the case where “Oda ○ O” is selected as the performer and “impressed scene” is selected as the specific scene. In this case, in S1424, the material ID to which the video content ID related to “impressed scene” is added together with the video content ID related to “Oda ○ male” is extracted.

  By executing the operation in this way, information related to broadcast information according to the viewer's preference is provided to the viewer at the material level (program advertisement, CM, etc.) regardless of the channel the viewer is viewing. can do. For this reason, it is possible to increase the possibility of viewers viewing broadcast information at the material level (program advertisement, CM, etc.), and dramatically increase the efficiency of advertisement and program advertisement.

  Note that a signal related to program information (including difference information and the like) is superimposed on a video signal and an audio signal transmitted from the predetermined broadcast station to the HDD recorder 600, and the program information (difference) is transferred from the predetermined broadcast station to the HDD recorder 600. (Including information etc.) may be distributed regularly or irregularly. Program information (including difference information and the like) may be distributed to the HDD recorder 600 in association with broadcast information from a broadcasting station.

  Note that for each operation shown in FIG. 28 and each operation shown in FIG. 35, a video viewing such as a digital television receiver having a communication function for communicating with the real-time program information server 1300 and a storage unit for storing program information. It can be applied to the device.

  By the way, recently, there are large-capacity recording / playback apparatuses such as DVD recorders and HDD recorders that can record a large number of TV programs, so that each time a TV program of interest is recorded using this recording / playback apparatus. The number of reservations is increasing. For example, when a recorded TV program is being watched, a large number of program advertisements and commercials are included during the broadcast of the TV program. Therefore, in order to watch only the main part of the TV program, There are cases where program advertisements and commercials are fast-forwarded and skip-played. In this case, a relatively large number of viewers can watch program advertisements and commercials, etc., and even though the viewer can be interested in the program, the viewer actually In many cases, advertisements and commercials are not seen, and there is a problem that the advertising efficiency of advertisements is poor.

  In addition, when the recorded TV program is viewed relatively later than the actual broadcast date, even if a program advertisement or CM included in the broadcast of the TV program is viewed, the advertisement effect has already been achieved. In this case, there is a problem that the advertising efficiency of the advertisement is poor.

  In this way, when an advertiser pays an advertising fee and advertises using TV broadcasting, a relatively large number of viewers can watch program advertisements and commercials, and are interested in many viewers. Despite being in a state where it can be displayed, there are many cases where viewers do not actually watch program advertisements or commercials, etc., and there are cases where the advertising effectiveness is low and the advertising efficiency is poor There is.

  According to each of the above-described embodiments, in the case where a program is promoted or commercialized using a television broadcast, the advertising efficiency of the program or commercial can be dramatically improved.
