  The broadcasting unit 1 detects and detects a video including a predetermined target object, target object position information that is position information on the screen of the target object, and a cursor position operated in a receiver on which the video is displayed. A program for collating the position of the cursor and the position of the target object is broadcast.

  Here, the broadcast video is a video that is normally broadcast on television. The target object means a predetermined object in the video, and is, for example, a person or a car in a real video, a computer graphic character in the real video, or the like, but is not limited thereto.

  The target object position information is information on the position of the target object in the video. As an example of the target object position information, for example, coordinates may be considered. When the target object is a character, a rectangle surrounding the entire character is assumed, and the coordinates of the four vertices of the rectangle or the coordinates of two opposite vertices may be used as position information. Further, the coordinates of the approximate center point of the character may be used as the target object position information. In addition, although the typical thing of target object position information was illustrated, it is not restricted to these. When there are a plurality of target objects, a plurality of pieces of target object position information may be combined into one.

  In the present embodiment, the target object position information as described above is transmitted (broadcast) at predetermined intervals (for example, every second). Further, every time the target object in the video moves, the target object position information may be transmitted (broadcast). Note that transmission (broadcasting) may be performed at predetermined intervals (for example, every second) regardless of the movement of the target object. As a transmission method, there are an event message defined in ARIB STD-B24, a transport private data area defined in MPEG, and a PES (Packetized Elementary Stream) private data area.

  The program broadcast from the broadcast unit 1 is a program for detecting the position of the cursor in the video by the operation unit 3 and collating the detected cursor position with target object position information. As a description method of this program, BML defined in ARIB STD-B24 is a typical one, but other methods may be used.

  The display unit 2 displays the video broadcast from the broadcast unit 1, and a typical example of the display unit 2 is a display of a television receiver.

  The operation unit 3 is used by a viewer to operate the cursor on the video displayed on the display unit 2, and a typical example of the operation unit 3 is a remote control of a television receiver or the like.

  The collation unit 4 collates the position of the target object with the position information of the cursor based on the broadcast program. A typical example of the collation unit 4 is an information processing device provided inside a television receiver, and is an information processing device that operates by BML for data broadcasting.

  The event generation unit 5 generates an event based on the collation result of the collation unit 4. Here, for the occurrence of the event, for example, when the TV receiver itself generates an event that displays an object reflecting the collation result in the video, or the collation result is reflected in the video from the broadcasting unit 1. There are cases where objects are generated. Further, collation results may be collected from a plurality of collation units 4 and the above events may be generated based on the results.

  With such a configuration, it is possible to provide a service that enables an active experience by a viewer such as a game by television broadcasting.

  Hereinafter, specific embodiments will be described.

By pressing the target object displayed on the touch panel via the display, The moving target object is specified, and the coordinates of the position are acquired. In this example, the coordinates of a predetermined center position of the specified target object are acquired. If the position where the target object moves is known in advance, such as a character, the coordinates of the position at predetermined intervals are acquired in advance, and the coordinates of the position are output at regular intervals. good.

  The target object position information generation unit 12 receives the target object position coordinates from the target object position detection unit 11 and converts them into information that can be put on the event message to generate target object position information.

  The event message generator 13 stores the position information from the target object position information generator 12 in a private area of the event message and sends it out.

  The BML storage unit 14 stores BML in which a script for causing the functions of the collation unit 4 and the event generation unit 5 described above to be performed in the television receiver is stored. Specifically, the position information of the target object is acquired from the event message, the position of the cursor operated in the receiver on which the broadcast video is displayed is detected, and the position of the target object and the detected cursor position are detected. And match. And according to the result of collation, an event is generated on the display of the television receiver. An example of BML is shown in FIG.

  The BML shown in FIG. 3 uses the predetermined position of the character as the center point, acquires its coordinates as target object position information, and for collation, the position at which the determination button of the remote control 26 described later is pressed is the position of the cursor. Detect as position. A process for generating an event (winning) is described when the position of the detected cursor is within a range of 10 × 10 dots centering on the coordinates of the target object.

  The multiplexing unit 15 multiplexes and broadcasts the video, the BML stored in the BML storage unit 14, and the event message from the event message generation unit 13.

  The display unit 23 is a display and displays the broadcast video.

  The collation unit 24 operates by BML (program), detects the position of the cursor operated by the remote controller 26, and collates the detected cursor position with the target object position information received by the event message.

  The event generation unit 25 generates an event based on the verification result of the verification unit 24. For example, “Win” is displayed on the display unit 23.

  Next, the specific operation of the present embodiment will be described with reference to FIG. 5 showing the transition of the screen displayed on the display unit 23 of the television receiver 20.

  First, a broadcast video is displayed on the display unit 23 of the television receiver 20, and a target object is also displayed in the video. A cursor operated by the remote control 26 is also displayed (state A).

  Subsequently, when the remote controller 26 is operated by the viewer, the cursor moves accordingly (state B). Then, the position of the cursor operated by the remote control 26 is detected, the detected cursor position is compared with the target object position information received in the event message, and the cursor position matches the target object position. If so, raise an event. In addition, although it is collation with the position of a cursor and a target object position, not only when the position coordinate of a cursor and a target object position coordinate correspond completely, for example, the position coordinate of a cursor is a target object position coordinate. If it is within a predetermined range as the center, the cursor position and the target object position may be treated as matching.

  Furthermore, the occurrence of the event is not limited to once, and may be performed a plurality of times according to the number of times the cursor position matches the target object position. For example, as in the state C and the state D in FIG. 5, when the first cursor position and the target object position coincide with each other, an event in which a part of the target object is broken is generated (state C). An event that causes the target object to explode may be generated when the cursor position matches the target object position (state C).

  In the first embodiment, a television receiver can be made like a game machine, and an active experience type service by a viewer can be provided by television broadcasting.

<Second Embodiment>
Next, a second embodiment of the present invention will be described.

  In the second embodiment, in each television receiver, an event for transmitting the determination result is generated in an aggregation server that aggregates the determination result of each television receiver. In the aggregation server, a matching result is obtained from a plurality of television receivers. And the event is generated in the video broadcast by the broadcasting station from the result. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 6 is a block diagram of a television receiver according to the second embodiment.

  The difference between the television receiver 20 of the second embodiment and the television receiver 20 of the first embodiment is that a verification result transmission unit 26 is provided instead of the event generation unit 25.

  The collation result transmission unit 26 transmits the collation result of the collation unit 24 to the aggregation server described later. That is, an event of sending the verification result is generated. The transmission of the collation result may be limited to, for example, only when the position of the cursor operated in the receiver matches the position of the target object.

  FIG. 7 is a block diagram of the aggregation server according to the second embodiment.

  The aggregation server 40 includes a verification result receiving unit 41, a verification result totaling unit 42, and an event trigger generating unit 43.

  The event trigger generation unit 43 generates an event trigger according to the totaling result of the collation result totaling unit 42. For example, an event trigger is generated when the number of matching results in which the position of the cursor matches the position of the target object exceeds a predetermined threshold.

  FIG. 8 is a block diagram of the broadcasting station 10 according to the second embodiment.

  The broadcast station 10 according to the second embodiment differs from the broadcast station 10 according to the first embodiment in that a video event generator 16 is provided in addition to the broadcast station 10 according to the first embodiment. It is. Further, the BML storage unit 14 stores a BML in which a script for generating an event for transmitting a determination result to the aggregation server is described instead of the occurrence of the event in the BML shown in FIG. An example of this BML is shown in FIG.

  The video event generation unit 16 receives a trigger from the event trigger generation unit 43 of the aggregation server 40 and generates an event in the broadcast video. For example, the video of the total result or the video in which the video of the target object changes is generated in the broadcast video. Note that a video to be broadcast may be stored in advance. The broadcast station 10 will broadcast the video in which the event occurred.

  In the present embodiment, in each television receiver 20, since the television receiver 20 itself does not need to generate an event, the broadcast program acquires the position information of the target object from the event message and is broadcast. It is only necessary to have a function of detecting the position of the cursor operated in the receiver on which the displayed video is displayed and collating the position of the target object with the position of the detected cursor. There is no need for a program for generating an event on the display.

  Next, the specific operation of the present embodiment will be described with reference to FIG. 10 showing the transition of the screen displayed on the display unit 23 of the television receiver 20.

  Subsequently, when the remote controller 26 is operated by the viewer, the cursor moves accordingly (state B). Then, the position of the cursor operated by the remote control 26 is detected, the detected cursor position is compared with the target object position information received in the event message, and the cursor position matches the target object position. In this case, the collation result is transmitted to the aggregation server 40.

  The totaling server 40 receives the verification results transmitted from each television receiver 20 and totals the verification results of each receiver. For example, the number of matching results in which the position of the cursor matches the position of the target object.

  The aggregation server 40 generates an event trigger according to the aggregation result. For example, an event trigger is generated when the number of matching results in which the position of the cursor matches the position of the target object exceeds a predetermined threshold. At this time, the occurrence of the event is not limited to once, and may be performed a plurality of times according to the number of matches between the cursor position and the target object position. For example, the number of matches between the cursor position and the target object position is displayed as 250, 500, 1000 as in the state B, state C, and state D in FIG. This trigger may be generated.

  In response to the event trigger, the TV broadcast station generates an event that displays the number of hits in the actual video and broadcasts it. At this time, an event in which a part of the target object is broken is generated (state C), and when the hit count reaches a predetermined number (for example, 1000 times), an event that causes the target object to explode is generated. Is good (state D).

  In the second embodiment, the television receiver can be made like a game machine, and an active experience-type service with a large number of viewers can be provided by television broadcasting.

  Obviously, the first embodiment and the second embodiment described above may be used in combination. That is, it is possible to make a hit determination by the television receiver alone and display the result on the television receiver, transmit the determination result to the aggregation server, and receive the video reflecting the aggregation result by broadcast waves. it can.
