(Embodiment 1)
1. Program Information Providing System FIG. 1 is a configuration diagram of a program information providing system according to the first embodiment. The illustrated program information providing system is a program information providing system that provides video data of a television program as content to a user. In a television program system, channels and programs (contents) are associated with each other in a predetermined viewing time zone. For this reason, in the first embodiment, the viewing time zone and the channel being viewed are specified in comparison with a so-called program table in which channels, scheduled broadcast times, and programs are associated with each other.

The program information providing system of Embodiment 1 requests a user fixed terminal 101 to transmit information (program information) related to a television program, and receives a program information transmitted in response to the request (Embodiment 1). Here, it is described as a user mobile terminal 103), and a program information providing apparatus 102 that creates and transmits program information in response to a request.
The user fixed terminal 101 is, for example, a television or a personal computer, and a mobile phone is used as the user mobile terminal 103, for example. Further, in recent years, as in the one-segment system, it is also possible to view television on a mobile terminal, so that a mobile terminal can be used instead of a user fixed terminal. Further, a single one-segment mobile terminal may function as the user fixed terminal 101 and the user mobile terminal 103.

  The user fixed terminal 101 includes a viewing channel acquisition unit 114 that acquires a viewing channel selected by a user, and a channel viewing time acquisition unit 113 that acquires information about a time zone in which the viewing channel is selected. The “time zone” when the channel is selected is information including the time when the channel is switched and the time when the channel is switched to another channel again.

In the first embodiment, the time zone in which the channel is selected is “viewing time zone”, and the time obtained by subtracting the time when the channel is switched to another channel from the time when the channel is switched to another channel is referred to as “ Also referred to as “viewing time”.
The user fixed terminal 101 determines whether channel selection, that is, viewing in the viewing time zone is zapping based on the viewing channel and viewing time, and creates viewing channel information based on the determination result. Is further provided. The viewing channel information is information including a viewing channel and a viewing time zone corresponding to the viewing channel. The viewing channel information is transmitted to the program information providing apparatus 102 by the viewing channel information transmission unit 112.

The user mobile terminal 103 includes a program information acquisition request transmitting unit 131 that requests the program information providing apparatus 102 to transmit program information, a program information receiving unit 132 that receives program information transmitted in response to the request, and the received program information Is stored with a personal program information storage unit 133.
The program information providing apparatus 102 includes a broadcast program receiving unit 130 that receives broadcast program data (hereinafter referred to as video data) on a television, a broadcast program storage unit 121 that stores the received video data, and the stored video data. A broadcast program type determination unit 120 that determines whether or not there is corresponding program metadata is provided. Note that the program metadata is information related to the video data of the program, and includes data creation date and time, creator, data format, title, annotation, and the like.

  The determination of the broadcast program type by the broadcast program type determination unit 120 can be realized as follows, for example. That is, a program ID for specifying a broadcast program is attached to each broadcast program, and a program metadata ID is attached to the program metadata. Then, the program ID and the program metadata ID corresponding to the program ID are managed as a program metadata related to the broadcast program using a DB table (not shown) or the like.

The broadcast program type determination unit 120 searches the program metadata storage unit 128 for program metadata having a program metadata ID corresponding to the broadcast program ID. As a result of the search, if there is program metadata, it is determined that program metadata exists, and if there is no program metadata, it is determined that there is no program metadata in the broadcast program.
The program information providing apparatus 102 includes a program metadata acquisition unit 129 that acquires program metadata, a program metadata storage unit 128 that stores the acquired program metadata, and a broadcast time for each program scene from the stored program metadata A segment information acquisition unit 124 that acquires segment information in which a band is described is provided.

  The program information providing apparatus 102 includes a video scene analysis unit 123 that detects scene breaks from video data and extracts a time stamp from the scene breaks. When the program metadata does not exist, in the first embodiment, the video scene analysis unit 123 extracts a time stamp. Note that, as a method for analyzing a video scene, for example, a method of detecting an excitement of audio or a change in camera angle as a scene break can be considered. Since such an analysis method is known, further explanation is omitted.

In addition, the program information providing apparatus 102 includes a chapter generation unit 125 that receives the segment information acquired by the segment information acquisition unit 124 or the time stamp extracted by the video scene analysis unit 123 and generates a chapter. A chapter is video data with a shorter plurality of broadcast times generated by dividing video data into scenes.
The segment information acquisition unit 124 acquires segment information describing a broadcast time zone from the program metadata stored in the program metadata storage unit 128 and passes it to the chapter generation unit 125. The chapter generation unit 125 receives the segment information, divides the video data for each appropriate broadcast time zone based on the segment information, and generates a chapter.

  On the other hand, the video scene analysis unit 123 passes the extracted time stamp to the chapter generation unit 125. The chapter generator 125 divides the video data with the time stamp as a delimiter to generate chapters. In the first embodiment, at this time, it may be determined whether or not the program metadata corresponding to the generated chapter can be acquired. If possible, the program metadata may be acquired and added to the chapter.

In the first embodiment, chapters can be generated regardless of whether or not video metadata includes program metadata.
In addition, the program information providing apparatus 102 includes a program information generation unit 126. The program information generation unit 126 acquires the program metadata corresponding to the chapter from the program metadata storage unit 128 and adds it to the corresponding chapter. In the first embodiment, information in which chapters are associated with broadcast times is used as program information, and program metadata is added to program information if acquisition is possible. Program information is stored in the program information storage unit 127.

  Furthermore, the program information providing apparatus 102 includes a viewing channel information receiving unit 115 that receives viewing channel information from the user fixed terminal 101, and a time information obtaining unit 116 that acquires time information related to a time zone in which a channel is selected from the viewing channel information. The content specifying unit 100 for specifying the content that has been viewed based on the viewing channel information and the time information, that is, the program is provided.

In the first embodiment, the content specifying unit 100 has the above-described program guide, and specifies the program by comparing the program guide with the viewing channel information.
Further, the program information providing apparatus 102 extracts the requested program information from the program information storage unit 127 out of the program information of the program specified by the content specifying unit 100, and the user information from the user mobile terminal 103. A program information acquisition request receiving unit 118 that receives a request for program information, and a program information transmission unit 119 that transmits program information to the user mobile terminal 103 in response to the request.

2. Operation In the program information providing system of the first embodiment described above, first, while the user is watching a television program on the user fixed terminal 101, the viewing channel acquisition unit 114 acquires information on the currently selected channel. Further, the channel viewing time acquisition unit 113 acquires the viewing time zone of this channel.
The zapping discriminating unit 111 determines, based on the viewing channel and the viewing time, whether viewing in the viewing time zone is for viewing the program or has occurred in the zapping process. Then, if it is determined that it occurred in the zapping process, the viewing channel information transmission unit 112 excludes the viewing time zone and viewing channel information related to viewing. Note that viewing exclusion processing related to zapping will be described later.

  On the other hand, the user transmits a program information acquisition request regarding the TV program being viewed from the program information acquisition request transmission unit 131 of the user mobile terminal 103 to the program information providing apparatus 102. The program information acquisition request is received by the program information acquisition request receiving unit 118 of the program information providing apparatus 102. The content identification unit 100 identifies the program that was viewed from the viewing channel information and the time information. The program information extraction unit 117 associates the program information acquisition request with the viewing channel information notified from the user fixed terminal 101, and extracts the program information of the requested program from the program information storage unit 127.

The program information is passed to the program information transmission unit 119 and transmitted to the user mobile terminal 103. The transmitted program information is displayed on a display unit (not shown) on the user mobile terminal 103.
The user confirms the chapter of the displayed program information and selects the program information to be acquired for each chapter. The selected program information is stored in the personal program information storage unit 133. The program information stored in the personal program information storage unit 133 can be confirmed after viewing the program. In the first embodiment, hereinafter, selecting program information and storing it in the personal program information storage unit 133 is also referred to as “registration” of the program information.
In the present embodiment, as indicated by a broken line in FIG. 1, the history information R is transmitted from the user mobile terminal 103 to the zapping determination unit 111 of the user fixed terminal via the program information providing apparatus 102. . The history information R is information indicating a registration history of program information in the user mobile terminal 103.

3. Determination of zapping Next, determination of zapping according to the first embodiment will be described.
FIG. 2 is a flowchart for explaining processing of the entire program information providing system according to the first embodiment.
The flowchart shown in FIG. 2 starts when a program information acquisition request is received from the program information providing apparatus (step S201). The viewing channel acquisition unit acquires viewing channel information that identifies the currently selected channel in the user fixed terminal (step S202). In parallel, a viewing time (referred to as viewing time length in the figure) X is acquired from the viewing time zone of the program corresponding to the selected channel (step S203).
The zapping determination unit compares the viewing time X with a preset threshold Y, and determines whether the viewing time X is shorter than the threshold Y (step S204). Note that the threshold value Y is desirably set to a short time of about 10 seconds, for example.

  When the viewing time X is shorter than the threshold Y (step S204: Yes), the zapping determination unit determines that the program is viewed during the zapping process (step S205). When the zapping discriminating unit determines that the viewing is performed in the zapping process, the channel information related to viewing and the information related to the viewing time zone are deleted (step S206). Does not transmit channel information. In the first embodiment, such processing is also referred to as “exclude” or “ignore” in creating viewing channel information.

As a result, the channel viewing information of the program whose viewing time is shorter than the threshold Y is not transmitted to the program information providing apparatus, and the program information extracting unit can extract the viewing program information generated in the zapping process. No (step S207).
On the other hand, when the channel viewing time X is longer than the threshold Y (step S204: No), the zapping determination unit determines that the viewer is watching the program (step S208). Then, the viewing channel information is transmitted based on the viewing channel and the viewing time zone. The generated viewing channel information is transmitted to the program providing device, and the program information extraction unit extracts the program information based on the viewing channel information (step S210). Of the steps described above, a series of processes including step S202 to step S210 is also referred to as flow1.

  Through the above processing, the program providing system of Embodiment 1 can transmit only the program information of the program that the viewer intended to watch to the user mobile terminal 103 and display it (step S211). For this reason, it becomes possible for the viewer to receive a high-quality service without the inconvenience of sending program information of a program viewed for the purpose of zapping.

4). Chapter Generation FIG. 3 is a flowchart for explaining the processing of the chapter generation unit 125 shown in FIG. The broadcast program determination unit determines the presence / absence of program metadata of the broadcast program (step S401). As a result of the determination (step S402), when there is no program metadata (step S402: No), the video scene analysis unit analyzes the broadcast data to determine a scene break and the like, and extracts a time stamp (step S403).

The chapter generation unit generates a chapter using the extracted time stamp (step S404). Further, related information is assigned to the generated chapter as necessary (step S405), and it is determined whether or not the chapter program metadata can be acquired from the outside (step S406). If the program metadata can be acquired (step S406: Yes), the acquired program metadata is added to the chapter to generate program information (step S407).
If the program metadata cannot be acquired (step S406: No), the process is terminated as it is.

  On the other hand, when it is determined in step S402 that the metadata of the broadcast program is stored in the program metadata storage unit 128 (step S402: Yes), the chapter generation unit displays the video based on the segment information of the program metadata. Broadcast time periods of a plurality of scenes constituting the data are acquired (step S408). The chapter generation unit generates chapters by dividing the video data based on the broadcast time period (step S409). Program metadata is assigned to each chapter (step S407). As a result, program information including chapters, chapter broadcast times and program metadata is generated.

Of the processes described above, a series of processes including steps S401, S402, S408, and S409 is performed in the steps of flow2, step S401, step S402, step S403, step S404, step S408, and step S409. This series of processing is also referred to as flow3.
In the program information providing system of the first embodiment described above, the user fixed terminal 101 corresponds to the video data viewing terminal, the program information providing apparatus 102 corresponds to the program information providing apparatus, and the user mobile terminal 103 corresponds to the mobile terminal.

  Also, the viewing channel acquisition unit 114 functions as a content specifying unit, the channel viewing time acquisition unit 113 functions as a viewing time zone acquisition unit, and the zapping determination unit 111 functions as a viewing channel information transmission unit and a zapping determination unit. The broadcast program type determination unit 120, the video scene analysis unit 123, the segment information acquisition unit 124, the chapter generation unit 125, and the program information generation unit 126 function as program information creation means.

5). Modification Furthermore, the program information provision system of Embodiment 1 is not limited to the structure shown in FIG. 1, It can also be comprised like FIG. 4 or FIG. In the configuration shown in FIG. 4, the personal program information storage unit 133 of the user mobile terminal 103 shown in FIG. 1 is arranged in the program information providing apparatus 102. The user mobile terminal 303 is provided with a personal program information display unit 310 instead of the program information transmission unit 119.
In this way, the program information registered by the viewer can be stored in the program information providing apparatus 302 and transmitted and displayed in response to a request from the user mobile terminal 103. The configuration shown in FIG. 4 is more advantageous for downsizing the memory of the user mobile terminal 303 and thus downsizing the device than the configuration shown in FIG.

  In the first embodiment, for example, as illustrated in FIG. 5, the zapping determination unit 111 may be provided on the program information providing apparatus 602 side instead of the user mobile terminal 601. In such a case, the zapping determination unit 111 determines zapping based on the viewing channel included in the viewing channel information and the viewing time of the channel. The content specifying unit 100 ignores the viewing channel information related to viewing that is determined to be zapping by the zapping determination unit 111 so as not to specify the content.

(Embodiment 2)
Next, a program information providing system according to the second embodiment of the present invention will be described. Note that the program information providing system of the second embodiment has the same configuration as that of the first embodiment, and is different from the first embodiment only in a specific method for determining zapping. Therefore, in the second embodiment, the illustration of the program information providing system and a part of the description thereof are omitted.
The purpose of the second embodiment is to detect a program A that is judged not to be zapping because it has been viewed in the zapping process but has satisfied the viewing time of the threshold Y, and to improve the zapping detection accuracy. It is a thing.

  FIG. 6 is a flowchart for explaining zapping processing according to the second embodiment. As shown in the drawing, in the first embodiment, after the user fixed terminal makes a request for program information acquisition from the program information providing apparatus (step S301), the flow1 process shown in FIG. 2 is executed (step S302). Then, as in the first embodiment, only the program information that is determined to have been intentionally viewed by the viewer is displayed on the display unit (not shown) of the user mobile terminal 103 (step S303).

At this time, in Embodiment 2, the history information R relating to the registration of the program information is notified from the user mobile terminal to the zapping determination unit via the program information providing apparatus.
The difference between the viewing time Y ′ and the threshold value Y is equal to or less than a predetermined time among at least one of the programs (adjacent contents) viewed immediately before viewing and viewing immediately after viewing determined to be zapping. Detect programs that are Then, the registration history information R of the program information included in the detected program A is confirmed (step S304).

Further, when the history information R does not include the registration history of the program information included in the program A (step S307: No), the zapping determination unit determines that the program A is also viewed during the zapping process (step S305). Then, the zapping threshold Y is corrected to the viewing time Y ′ of the program A (step S306).
On the other hand, in step S307, when the history information R includes the registration history of the program information included in the program A (step S307: Yes), the zapping determination unit 111 determines that the program A is not zapping (step S308). At this time, the threshold value Y used for the determination of zapping is stored as it is (step S309).

  The second embodiment described above is not limited to such a configuration. For example, in the second embodiment, only a program viewed immediately before and immediately after a program determined to be zapping is not a target for redetermination of zapping. A predetermined number of programs viewed before the program determined to be zapping and a predetermined number of programs viewed after the program determined to be zapping may be re-determined.

(Embodiment 3)
Next, a program information providing system according to the third embodiment of the present invention will be described. The program information providing system of the third embodiment has the same configuration as that of the first embodiment, and differs from the first embodiment only in a specific method for determining zapping. For this reason, in the third embodiment, a part of the illustration and description of the program information providing system is omitted.
Embodiment 3 aims to set the time length of one chapter more appropriately when the chapter generation unit divides video data to generate chapters.

  FIG. 7 is a flowchart for explaining chapter generation processing according to the third embodiment. As illustrated, in the third embodiment, program information including chapters is selected in the user mobile terminal (step S701). The chapter generation unit of the program information providing device refers to the history information R and determines whether or not a plurality of program information corresponding to successive chapters (scenes) is registered in the user mobile terminal or the program information providing device (step). S702).

As a result of the determination, if program information with continuous chapters is not registered (step S702: No), the flow 3 process shown in FIG. 3 is executed to generate chapters (step S703). The generated chapter is displayed as program information on the user mobile terminal 103 (step S708).
On the other hand, when it is determined in step S702 that a plurality of program information corresponding to successive chapters is registered (step S702: Yes), the chapter generation unit determines the time length of the plurality of chapters of the registered program information. Is calculated (step S704). Then, the flow2 process shown in FIG. 3 is executed (step S705).

Further, when the chapter generation unit generates a chapter by dividing video data with the next time stamp, the chapter generation unit determines the broadcast time of one chapter as a reference value based on the average value of the previously calculated broadcast time (step). S706). Specifically, the broadcast data is divided by selecting a time stamp so that the broadcast time of one chapter is closest to the average value.
Further, even when generating a chapter based on the next segment information, the chapter generation unit determines the broadcasting time of one chapter as a reference value based on the previously calculated broadcasting time average value (step S707). Specifically, the broadcast data is divided by selecting a scene break so that the broadcast time of one chapter is closest to the average value.

For example, when the average value w is 40 seconds, the broadcast time zone of scene 1 indicated by the segment information is 0:00:00 to 0:00:30, and scene 2 is 0:00:30 to 0:00: 45, if the scene 3 is 0:00:45 to 0:01:00, the broadcast data broadcast in the time zone from 0:00:00 to 0:00:45 that combines the scene 1 and the scene 2 is 1 One chapter.
The chapter generated as described above is displayed on the user mobile terminal as program information together with the broadcast time zone and program metadata (step S708).
