Description

  The present invention relates to a digital broadcasting system, and more particularly to an apparatus and method for recording a digital broadcast on a storage medium such as a hard disk and viewing a part of the recorded video.

  In recent years, it has become common to record a digital broadcast program on a storage medium such as an HDD recorder and view it in response to a user request. A program reservation video recording service for instructing the program has been started. Such a technique is described in Patent Document 1.

Also, since the HDD can be accessed randomly, it is possible to start playback from a predetermined location by specifying the playback start position using a time code or the like. Conventionally, the playback start position specification for starting playback from an arbitrary position is generally created by the person who recorded the program while using the video editing application while viewing the program, and the program is broadcast. Normally, the program composition information is not provided from the broadcasting station.
JP 2002-7873 A

  Viewing an arbitrary portion of a program recorded by a viewer may lead to a decrease in CM advertisement viewing for a program provider, that is, a company that pays an advertising fee and broadcasts a commercial (CM) between programs. I can imagine it easily. Such a viewing method is inconvenient for a program provider, and thus a broadcasting station. Therefore, even if the broadcasting station has program configuration information that supports partial viewing, it is rarely provided to viewers.

  The present invention has been devised in view of the above problems.

  In order to solve this problem, the program information holding server 100 in the prior partial viewing method of the present invention has a reservation information receiving unit 101, an advertisement information sending unit 102, a program information holding unit 103, and a reproduction / editing program sending unit 104, The program reservation recording device 116 includes a recording reservation information transmission unit 105, an advertisement information acquisition unit 106, an advertisement viewing history transmission unit 107, an advertisement viewing information holding unit 108, an advertisement browsing unit 109, a recording reservation information holding unit 110, and an external device communication unit 111. By providing the playback / editing program holding unit 112, the program receiving unit 113, the program holding unit 114, and the playback / editing unit 115, the CM advertisement viewing means independent of the recorded program viewing means is provided to the user. It is possible to provide information that supports partial viewing only to viewers who watched CM advertisements before viewing recorded programs.

  The present invention provides an advance partial viewing device comprising: an information server that provides a program service according to a user's viewing history via a communication line; and a television broadcast recording device that can communicate with the information server; The information server sends advertisement information sending means for notifying the recording device of an advertisement corresponding to the reservation information received from the recording device, and a program service corresponding to the advertisement viewing history received from the recording device to the recording device. A program service sending means for providing the recording apparatus, a recording reservation information sending means for notifying the information server of the recording reservation information, an advertisement acquisition means for obtaining advertisement information corresponding to the recording reservation information, and a user An advertisement presenting means for presenting the selected advertisement, an advertisement viewing history sending means for notifying the information server of the user's advertisement viewing history, and the information server An external device communication unit configured to acquire program service according to tell viewing history, user; and a service execution unit configured to call and execute the program service when viewing a program.

  The present invention also provides an advance part in an advance partial viewing apparatus comprising an information server that provides a program service according to a user's viewing history via a communication line, and a television broadcast recording apparatus that can communicate with the server. An advertisement information acquisition step for providing a viewing method, in which the recording device notifies the recording server of recording reservation information to acquire advertisement information, and an advertisement viewing history storage step for storing the viewing history when the user views the advertisement And a playback / editing program acquisition step of notifying the information server of the advertisement viewing history of the recording device and acquiring a corresponding program service.

  In one embodiment of the present invention, the prior partial viewing method includes a recording reservation step in which the recording device makes a recording reservation in response to a user's recording reservation command, and a program recording in which the recording device records a designated program. And a playback / editing step in which the user executes a playback / editing program for the recorded program.

  The present invention also includes a program for executing the above-described method and a recording medium on which the program is recorded.

  As described above, according to the present invention, a viewer can view a CM advertisement before viewing a recorded program, thereby partially viewing the program when playing the program, or extracting a part of the program simply when editing the program. Is possible. In addition, the program provider can more reliably view the CM advertisement. Thereby, there is an effect that it is possible to provide a program viewing method that is advantageous to both the program provider and the viewer.

  Hereinafter, embodiments of the present invention will be described.

(Embodiment 1)
Hereinafter, the prior partial viewing method according to the first embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a functional block diagram showing an example of the configuration of a prior partial viewing apparatus used in the prior partial viewing method according to Embodiment 1 of the present invention.

  The operation of the partial prior viewing service using the partial partial viewing apparatus configured as described above will be specifically described with reference to the drawings.

  Here, the prior partial viewing service refers to a program that is arbitrarily selected by the user or automatically selected by the program reservation recording terminal and scheduled to be recorded by the program reservation recording terminal such as an HDD recorder before the actual viewing time. This is a service in which a part of a program, in this embodiment, the CM of the provider can be viewed in advance by a method other than program viewing, and the CM of the provider that has been viewed can be skipped during playback. Also, in the past, users have been using a video editing application to re-edit programs such as removing already watched CM parts of the provider or extracting only the necessary parts of the program. It is also a service that can.

  FIG. 2 is a diagram showing an example of advertisement information data held by the program information holding unit 103 shown in FIG. The program information holding unit 103 holds program configuration information (described later) and editing program information (described later) in addition to the advertisement information.

  The advertisement information includes “program name”, “broadcast time”, “provider company name” of the program, “product name” of the target CM, “URL” of the advertisement of the provider, and the like for each program.

  In normal television programs, CMs are broadcast before and after the main program and between programs. In the present invention, instead of viewing the CM in the program at the time of playing the recorded program, the recorded program playback is performed by accessing the URL specified by the provider before playing the recorded program and viewing the advertisement of the web content equivalent to the CM. In some cases, it is possible to implement an advance partial viewing service in which a CM of a provider that has already been viewed is skipped and played.

  “Program name” and “broadcast time” of the advertisement information are data necessary for specifying the program. The “providing company name” is a name of a company that broadcasts a commercial by paying an advertisement fee for the program, and a plurality of “providing company names” may exist for one program. If only a specific product of the provider is advertised, or if the product name is known to the public beyond the provider's name, it is easier for the user to select the advertisement because the product name is presented. The target “product name” is added to the advertisement information, but this information is not essential. “URL” is an address of an advertisement accessed when an advertisement viewing request is received from the user, and the user can view the advertisement of the WEB content by accessing this address.

  First, the advertisement information registration process will be described. A program provider that wishes to view advertisements of the WEB content of the provided program before playing the recorded program instead of viewing the CM in the program when playing the recorded program creates an advertisement of the WEB content and accesses the user The advertisement URL to be received is registered in the program information holding server 100. The program information holding server adds the registered URL to the advertisement information of the program provider.

  The advertisement information 201 is that a program provider whose program name is “World Travel” and whose broadcast time is “19:00 to 10:00 on October 1, 2003” is “provider company A” and “provider company B”. "And" providing company C ". “Providing company A” requests the user to view advertisements for the product “Shaver” placed at the URL “HTTP://www.teiyou_a.com” instead of viewing the CM in the “World Travel” program. It shows that you are doing. “Providing company B” indicates that instead of viewing the CM in the “World Travel” program, the user is requested to view the advertisement placed at the URL “HTTP://www.teiyou_b.com”. ing. “Providing company C” instead of viewing the CM in the “World Travel” program, advertisement of the product “domestic travel” placed at the URL “HTTP://www.teikyo_c.com/domestic” or “HTTP” : //Www.teikyo_c.com/broad ”” indicates that the user is requested to view the advertisement of the product “overseas travel”. As in the example of FIG. 2, one provider may register a plurality of URLs as advertisement information, and the user may be able to view advertisements according to preferences. Further, the advertisement of the WEB content does not necessarily relate to a product equivalent to the CM broadcast in the program.

  Next, the recording reservation process will be described. The program reservation recording device 116 accepts a recording reservation command (not shown) from the user, or the program reservation recording device 116 automatically determines (not shown) and reserves recording of a specific program. The details of reserved recording of programs, automatic selection of recorded programs, and recording processing operations of reserved recording programs are functions that are generally known by being installed in general-purpose devices such as HDD recorders. Because there is no, it is omitted.

  FIG. 3 is a diagram showing an example of recording reservation information data held by the recording reservation information holding unit 110. As recording reservation information, “program name”, “broadcast channel”, “broadcast time”, “status” of reservation, and “recording reservation reception time” are stored. The reservation information 301 indicates that a program whose program name is “Travel around the world”, the broadcast channel is “10”, and the broadcast time is “October 1, 2003 19:00 to 20:00” is “September 24, 2003”. 23:48 "indicates that" recording reservation "has been made.

  Next, the advertisement information acquisition process will be described. The program reservation recording device 116 notifies the recording reservation information to the program information holding server 100, and acquires advertisement information corresponding to the program.

  FIG. 4 is a diagram showing a flowchart of advertisement information acquisition in the program reservation recording device 116. The recording reservation information sending unit 105 detects the occurrence of a reservation recording command (S401), and if there is recording reservation information that has not been transmitted to the program information holding server 100, acquires a recording reservation information notification destination (S402). It transmits to the reservation information reception part 101 of the information holding server 100 (S403). In the present embodiment, since the program information holding server 100 is installed for each broadcasting station, the correspondence relationship between the broadcasting station and the notification destination of the recording reservation information is held in the program recording terminal 116, and the program is stored in the program. The recording reservation information is notified to the corresponding program information holding server 100. The advertisement information acquisition unit 106 acquires advertisement information from the advertisement information transmission unit 102 of the program information holding server 100 (S404), and stores the advertisement information in the advertisement viewing information holding unit 108 (S405).

  FIG. 5 is a diagram illustrating an example of reservation information data transmitted to the reservation information receiving unit 101. In the present embodiment, since the program information holding server 100 is installed for each broadcasting station, it is possible to specify a program that has been reserved for recording based on the program name or broadcasting time. In the present embodiment, both the program name and the broadcast time are transmitted as reservation information. Note that the program information holding server 100 may not be installed for each broadcasting station, and the program information of all broadcasting stations may be held by one server. In that case, since there is a possibility that the program cannot be specified only by the program name and the broadcast time, it is necessary to add a broadcast channel or the like to the recording reservation information. In this embodiment, the occurrence of a recording reservation command is detected and the recording reservation information is notified. However, the recording reservation information is checked at regular intervals, and if there is a change, the recording reservation is detected. Information notification processing may be performed, or notification processing may be performed by a user's recording reservation information notification command.

  FIG. 6 is a flowchart of advertisement information transmission in the program information holding server 100. The reservation information reception unit 101 monitors reception of reservation information from the program reservation recording device 116 (S601), and if there is reservation information, transfers the received reservation information to the advertisement information transmission unit 102. The advertisement information transmitting unit 102 specifies the program from the reservation information based on the data in the program information holding unit 103, acquires the corresponding advertisement information (S602), and transmits the advertisement information to the program reservation recording device 116 (S603). ).

  In the present embodiment, unified advertisement information is sent nationwide for the same program. However, depending on the broadcasting mode, the provider for the same program and the CM to be broadcast may be different for each region. In such a case, an item of “region code” is added to the advertisement information, and the advertisement information is held for each region. When receiving the reservation information from the program reservation recording terminal, the program reservation recording is recorded together with the reservation information. What is necessary is just to acquire the area code etc. in which the apparatus is installed, and to send the advertisement information of the area concerned.

  Here, the flow from when a new recording reservation command is generated until the advertisement information is stored in the advertisement viewing information holding unit 108 will be described with reference to the example of the figure.

  By the user's reserved recording process or the recorded program selection process of the program reservation recording apparatus 116, the program name is “Asia Travel”, the broadcast channel is “10”, and the broadcast time is “October 3, 2003 12:00:00 to 13:00. Recording reservation information is added to the recording reservation information holding unit 110.

  FIG. 7 is a diagram illustrating an example of recording reservation information data of the recording reservation information holding unit 110 when the recording reservation information of the above-described program is added to the recording reservation information of FIG.

  The recording reservation information sending unit 105 acquires the recording reservation information notification destination corresponding to the broadcast channel “10”, and sends the program name “Asia trip” and the broadcast time “2003” as the recording reservation information to the corresponding program information holding server 100. October 3rd, 12:00 to 13:00 ".

  The recording reservation information 501 in FIG. 5 is recording reservation information 501 notified to the program information holding server 100. The reservation information receiving unit 101 of the program information holding server 100 delivers the recording reservation information 501 received from the program reservation recording terminal 116 to the advertisement information sending unit 102. The advertisement information sending unit 102 starts from the program name “Asia trip” and the broadcast time “October 3, 2003 12:00:00 to 13:00”. ”Is specified, and advertisement information relating to“ provider company F ”and“ provider company G ”, which are advertisement information of the program, is acquired.

  8 is a diagram illustrating an example of advertisement information data extracted from the program information holding unit 103 and sent from the advertisement information sending unit 102 to the program reservation recording device 116.

  FIG. 9 is a diagram showing an example of program viewing information held by the advertisement viewing information holding unit 108. The advertisement viewing information includes “program name”, “broadcast channel”, “broadcast time” for specifying a program, “reservation status” indicating the current reservation status, and additionally acquired from the program information holding server 100. “Providing company name” that is the advertisement information corresponding to the program that has been played, “Product name” of the CM, “URL” of the advertisement that the user wants to view instead of the CM, and “Viewing” of the URL that is the advertisement viewing history of the user There are “number of times” and “information update flag”. The “information update flag” is a flag indicating whether the viewing history information is updated. This value becomes “1” when the viewing history of the program, in this embodiment “viewing count” is changed, and becomes “0” when the advertisement viewing history is sent to the program information holding server 100. Therefore, by referring to this value, it is possible to determine whether there is an advertisement viewing history that has not been sent to the program information holding server.

  The advertisement viewing information 901 is added by the advertisement information acquisition unit 106 acquiring the advertisement information 801 shown in FIG. Since the “URL” of the advertisement is not viewed at the time of addition, “0” is stored in the number of viewing times.

  The above is the flow from when the reservation recording command is generated until the advertisement information is stored in the advertisement viewing information holding unit 108.

  Next, an advertisement viewing process when the user views an advertisement will be described.

  The advertisement browsing unit 109 creates and presents to the user an “advertisement viewing selection screen” for allowing the user to select an advertisement to view based on the data of the advertisement viewing information holding unit. The “advertisement viewing selection screen” may be presented in response to a user request or when advertisement information is sent from the program information holding server 100 and information in the advertisement viewing information holding unit 108 is changed. Alternatively, it may be performed at regular intervals.

  FIG. 10 is a diagram illustrating an example of a service image of the advertisement viewing selection screen. In this embodiment, in order to make it easier for the user to select an advertisement, not only the “view” button 1001 for instructing viewing of the advertisement, but also the “program name”, “broadcast channel”, “broadcast time” and "Providing company name" and "product name" information is also presented. The information presented here is obtained from “program name”, “broadcast channel”, “broadcast time”, “provider company name”, and “product name” in the advertisement viewing information holding unit 108. The user operates the remote control up / down key to select an advertisement to be viewed from among the “advertisement selection buttons”, and can determine the advertisement to be viewed by pressing a determination button on the remote control. A “view” button 1001 is a currently focused button.

  The “view again” button 1002 is advertisement information that has already been viewed once. By placing a button labeled “View” for an advertisement whose “viewing number” in the advertisement viewing information is zero, and a button labeled “View again” for one or more advertisements, the viewer still has You can easily find advertisements you have not seen.

  The “View” button 1001 is associated with “HTTP: //www.teiyou_a.com”, which is the URL of the advertisement of the corresponding provider, and corresponds when the “Enter” button on the remote control is pressed when the “View” button 1001 is selected. WEB content for advertising “shaver” of “provider company A”, which is a product of the provider, is displayed. In other words, when the “view” button 1001 is pressed, the program reservation recording terminal 116 connects to an address whose URL associated with this button is “HTTP://www.teiyou_a.com”, such as an HTML document or the like. WEB content is acquired and presented. The display of WEB content by pressing a button is a function generally known in the data broadcasting service of BS digital broadcasting, and is omitted because it is not the main point of the present invention.

  When the user views the WEB content associated with the advertisement of the provider, the “viewing count” in the advertisement viewing information holding unit 108 increases by one. If the value of the “information update flag” is “0”, it is changed to “1”. In this embodiment, only the number of times of viewing is stored as the advertisement viewing history at the festival where the advertisement is viewed, but the history such as the time and the number of pages that were viewed may be stored, A determination result as to whether or not a specific operation has been performed may be stored as a history. Here, the specific operation that is beneficial to the provider is that when the provider conducts a questionnaire to the user with the WEB content in the URL of the advertisement or enables the user to purchase an advertising product from the WEB content. Refers to an action such as answering a questionnaire or purchasing a product.

  In this embodiment, the program viewing recording device 116 automatically generates an advertisement viewing selection screen in order to clarify the correspondence between the program and the advertisement to the user and to omit the URL input operation for connecting to the advertisement. However, the advertisement viewing selection screen is not always necessary, and the user can directly view the advertisement by directly entering the URL, or access the WEB content for supporting advertisement viewing and select the advertisement to be viewed from there. May be.

  Next, advertisement viewing history transmission processing and playback / editing processing will be described.

  FIG. 11 is a flowchart showing a processing flow of the program reservation recording device 116 when the user plays back or edits the recorded program. When receiving a playback or editing command of the recorded program from the user (S1101), the playback / editing unit 115 determines whether or not it is necessary to acquire the playback / editing program from the program holding information server (S1102). Specifically, when the program has never been reproduced or edited in the past, and when the advertisement viewing history is updated after the previous reproduction or editing, that is, when the “information update flag” is “1”, It is determined that playback / editing program acquisition is necessary, and otherwise it is determined unnecessary. If it is determined that the reproduction / editing program needs to be acquired, the advertisement viewing history of the program stored in the advertisement viewing history holding unit is notified to the program information holding server 100 (S1103), and the external device communication unit 111 The reproduction / editing program is acquired from the information holding server 100, the value of the “information update flag” is returned to “0” (S1104), and stored in the reproduction / editing program holding unit 112 (S1105).

  After storing in the reproduction / editing program holding unit 112 or when it is determined that acquisition of the reproduction / editing program is unnecessary, it is determined whether or not the instruction from the user is a reproduction instruction (S1106). If there is, a reproduction program for the program is extracted from the reproduction / editing program holding unit 112 and presented to the user (S1107). The reproduction method selected by the user is received (S1108), and when the user selects the reproduction program, the selected reproduction program is executed (S1109). When the user selects normal playback, playback is performed in the same manner as playback of a conventional scheduled recording program (S1110).

  If the command from the user is not a playback command, it is determined whether or not it is an editing command (S1111). If the command is an editing command, the editing program of the program is extracted from the playback / editing program holding unit 112 and presented to the user. (S1112). The editing method selected by the user is received (S1113), and when the user selects the editing program, the selected editing program is executed (S1114). If the user selects normal editing, an editing application for editing the video of the program is activated (S1115).

  FIG. 12 is a flowchart showing the flow of the reproduction / editing program sending process in the program information holding server 100. When receiving the advertisement viewing history from the program reservation recording device 116 (S1201), the playback / editing program sending unit 104 specifies the corresponding program from the program information holding unit 103 and acquires the program information (S1202), and the user advertisement viewing history. A reproduction / editing program distribution list in which all reproduction / editing programs matching the above are extracted is created (S1203), and all the reproduction programs and editing programs described in the reproduction / editing program distribution list are sent to the program reservation recording device 116. (S1204).

  Here, the reproduction / editing program will be described in detail.

  In the present embodiment, the playback program is a partial playback (playing back only a part of the program) or skip playback (playing back only a part of the program) for a program reserved for recording and held in the program holding unit 114. ) And a program that specifies a playback method for continuously performing a combination of partial playback and skip playback.

  In the present embodiment, the editing program refers to an operation that is usually performed manually by a user using an editing application or the like for a program reserved for recording and held in the program holding unit 114, specifically, This is a program that automatically extracts only a specific video part or assigns a title. A single editing program that uses a procedural language, etc. for multiple work processes such as extracting only a specific video portion of a program, connecting the extracted videos, and converting them to a specific format As a result, it is possible to easily create an edited video suitable for the purpose.

  The reproduction / editing program distribution list creation process will be described below.

  FIG. 13 is a diagram showing an example of program configuration information. Each program can be divided into a plurality of corners according to the broadcast contents, and each corner can be expressed using relative time from the broadcast start time. The composition of the program can be expressed by “end position”, “category” of CM or the main part of the program, and “broadcast content” indicating the provider company name or the corner name. FIG. 13 shows program configuration information of the “World Tour” program. For 3 minutes from the broadcast start time, CMs of “provider company A”, “provider company B”, and “provider company C” are broadcast for one minute each, then “opening” of the main part of the program is 7 minutes, and 4 videos about “Phuket” It shows that the CM of “provider company A” is broadcast for 1 minute, and then the video regarding “Phuket” is broadcast for 10 minutes.

  FIG. 14 is a diagram showing an example of editing program information data held in the program information holding unit 103. The “title” and “edit program name” to be given to the organized video and the “distribution condition” indicating what conditions are to be distributed to users who satisfy the conditions and the substance of the edit program (not shown) are stored. ing. Organizing program information exists for each program.

  The editing program 1401 views the advertisement URL of “provider company A”, the advertisement URL of “provider company B”, and the user who has viewed the advertisement URL of “provider company C” as a “world travel-digest version”. If the user edits a “World Tour” program using the edit program, the title “World Tour-Digest Version” is given to the title. ing.

  FIG. 15 is a flowchart showing the flow of the reproduction / editing program distribution list generation process. The playback / editing program transmission unit 104 acquires “provider company name” and “URL” from the program information of the target program (S1501), and compares the advertisement viewing history acquired from the program reserved recording terminal 116 with the user. The “providing company name” that has been viewed is specified (S1502). Thereafter, the program configuration information of the target program is acquired (S1503), and the following processing is repeated for the number of program corners. Corner information is acquired for each corner of the program (S1505), and it is determined whether the category is a program (S1506). If it is a CM, it is determined whether or not the CM is a “provider company name” that has already been viewed (S1507). If the category is a program and if the CM is not a “provider company name” that has already been viewed, the corner is added to the reproduction target list (S1508). After completion of the process of determining whether to add all the corners to the reproduction target list, a program is created to connect all the corners of the reproduction target list for reproduction (S1511), and the reproduction program is added to the reproduction / edit program distribution list. (S1512). Thereafter, the editing program information of the target program is acquired (S1513), and the following processing is repeated for the number of editing programs. Editing program information is acquired for each editing program (S1515), whether or not the distribution condition is satisfied is determined (S1516), and if the distribution condition is satisfied, the editing program is added to the reproduction / editing program distribution list (S1517). After all the editing programs have been processed for determining whether to add to the reproduction / editing program distribution list, the processing ends.

  Here, the flow from when the user views an advertisement to issue a recorded program playback command and when the playback / editing program is stored in the playback / editing program holding unit 112 will be described with reference to the example of the drawing.

  When the user instructs to play the “World Tour” program, the advertisement viewing history sending unit 107 refers to the “information update flag” of the program, and since it is “1”, the advertisement viewing history of the program is stored in the program information holding server. Notice.

  The advertisement viewing history 1601 in FIG. 16 is a diagram showing an example of the advertisement viewing history notified to the program information holding server.

  The playback / editing program sending unit 104 receives the advertisement viewing history 1601 and selects a program whose program name is “World Travel” and broadcast time is “October 1, 2003 19:00:00 to 20:00” in the program information. After searching and identifying which program's advertisement viewing history is received from the user, creation of a reproduction / editing program distribution list is started.

  The playback / editing program transmission unit 104 compares the advertisement “URL” of the target program “World Travel” with the advertisement viewing history 1601 so that the user can view the advertisements of “providing company B” and “providing company C”. You can see that it is done. After that, the program composition information of the target program “World Travel” is acquired, and addition determination to the playback target list is performed sequentially from the top corner.

  As a result of the determination process, the “1”, “4”, “5”, “6”, “7”, “8”, “10”, “11”, “13”, “14”, and “17” corners are added to the reproduction target list. A program for reproducing by connecting is generated, and the reproduction program is added to the reproduction / editing program distribution list. After that, the editing program information of the target program “World Tour” is acquired, and addition determination to the reproduction / editing program distribution list is performed for the number of editing programs.

  The distribution condition of “World Travel-Digest Version” is to watch “provider company A”, “provider company B”, and “provider company C”, but the users are “provider company B” and “provider company C”. Therefore, it is determined that the distribution condition is not satisfied, and the editing program “World Tour-Digest Version” is not added to the reproduction / editing program distribution list.

  The distribution condition of “Phuket Journey” is to watch “provider company A” or “provider company B”, but the user meets “distribution company B” and “provider company C”, so it satisfies the distribution condition. The editing program “World Tour-Phuket Travel” is added to the reproduction / edit program distribution list.

  As a result, the playback program and the editing program “1”, “4”, “5”, “6”, “7”, “8”, “10”, “11”, “13”, “14”, and “17” are connected. "World Tour-Phuket Tour" is transmitted to the program reservation recording terminal 116.

  The reproduction / editing program created as described above is transmitted to the program reserved recording terminal 116 and used by the user.

  In this embodiment, a playback program is automatically generated, and a plurality of editing programs are created in advance and sent according to the distribution conditions. However, a plurality of playback programs are created and distributed in advance. Only those that meet the conditions may be sent out, or an editing program may be automatically generated.

  In this embodiment, the advertisement viewing history transmission process is executed immediately before the reproduction / editing process. However, the advertisement viewing history transmission process may be performed in advance before the reproduction / editing process is performed.

  Since the recording process is a general function in general-purpose equipment such as an HDD recorder, the description thereof is omitted. However, in order to perform the playback / editing process, the recording process needs to be executed before that. There is.
