  Next, details of the image display apparatus 1 will be described. FIG. 3 is a block diagram for explaining the image display device 1 and the broadcasting station 100.

  The broadcasting / communication cooperation system including the image display device 1 and the broadcasting station 100 links broadcasting services provided by broadcast waves with communication services provided from the server 120 via a communication network, thereby performing broadcasting communication. Provide linked services to users.

  The broadcasting station 100 includes a broadcasting device 110 and a server 120. The broadcast device 110 broadcasts a moving image using a broadcast wave. The server 120 stores a plurality of moving images. The server 120 transmits the stored one or more moving images to the image display device 1 via the communication network. Here, the moving image may be referred to as content. The broadcast device 110 and the server 120 share a system clock when transmitting a moving image from each to the image display device 1. That is, the broadcast device 110 and the server 120 add information indicating the reference clock to the moving image to be transmitted.

  The image display device 1 includes a first image output unit 10, a second image output unit 20, a first reception unit 31, a first synchronization buffer 32, a request generation unit 33, a second reception unit 34, A second synchronization buffer 35, a synchronization unit 36, a switching unit 37, a speaker 38, and a control unit 39 are provided. Here, in FIG. 3, the first image output unit 10 is simplified and described as “first display unit 10”. In FIG. 3, the second image output unit 20 is simplified and described as “second display unit 20”.

The first receiving unit 31 receives a moving image transmitted from the broadcasting station 100 by a broadcast wave. That is, the first receiving unit 31 receives a moving image transmitted from the broadcasting device 110 by a broadcast wave. The first receiving unit 31 is, for example, a tuner and a decoder. The first receiving unit 31 acquires a reference clock from the received moving image and outputs it to the control unit 39 described later.
The first synchronization buffer 32 temporarily stores the moving image output from the first receiving unit 31.

  When there is a request request from the user, that is, for example, when there is a video transmission request after a hybrid cast button (not shown) of the remote controller 40 (see FIG. 4) is operated, the request generation unit 33 , A request is transmitted to the server 120. The server 120 transmits a moving image to the image display device 1 in response to the request.

The second receiving unit 34 receives one or a plurality of moving images transmitted from the server 120 via the communication network. The second receiving unit 34 is, for example, a decoder.
The second synchronization buffer 35 temporarily stores the moving image output from the second reception unit 34.

  The synchronization unit 36 synchronizes the moving image received by the first receiving unit 31 and one or more moving images received by the second receiving unit 34. That is, the synchronization unit 36 adds the reference clock supplied from the control unit 39 and the moving image stored in the first synchronization buffer 32 and the moving image stored in the second synchronization buffer 35 to each moving image. Take synchronization based on the reference clock you have.

  The switching unit 37 switches the display destination of the moving image, which of the first image output unit 10 and the second image output unit 20 displays the moving image. That is, the switching unit 37 switches the output destination for displaying the synchronized moving image received from the first synchronization buffer 32 and the second synchronization buffer 35. The switching unit 37 is controlled by a control unit 39 to be described later. As an example, the switching unit 37 switches the display of moving images based on the operation of the remote controller 40 by the user.

FIG. 4 is a diagram for explaining an example of the remote controller 40.
The remote controller 40 communicates with the image display device 1 by wireless communication, for example. For this reason, the remote controller 40 can receive and display a moving image transmitted from a communication unit (not shown) of the image display device 1 and can transmit an instruction to the image display device 1. .

  The remote controller 40 displays buttons and the like on a touch screen display, for example. On the left side of the remote controller 40, a channel button and a volume button are displayed. In the upper right area 40a of the remote controller 40, the moving image transmitted from the image display device 1 is displayed. The lower right area 40b of the remote control 40 is an area (television area 40c) to which a moving image to be displayed on the first image output unit 10 (television) is allocated, and the second image output unit 20 (left side) arranged on the left side of the image display device 1. : A region (left region 40d) for assigning a moving image to be displayed on the left second image output unit 20c), a second image output unit 20 (previous: front second image output unit 20a) disposed on the upper surface of the image display device 1 A region for assigning a moving image to be displayed (front region 40e) and a region for assigning a moving image to be displayed in the second image output unit 20 (right: right second image output unit 20b) arranged on the right side of the image display device 1 (right There is a region 40f).

  As an example, when “moving picture 1” displayed in the upper right area 40a is dragged to the television area 40c, the remote control 40 displays a signal for displaying “moving picture 1” on the first image output unit 10 (television). Is transmitted to the image display apparatus 1. Further, as an example, when the “moving image 2” displayed in the upper right area 40a is dragged to the front area 40e, the remote controller 40 displays the second image output unit 20 (front second) arranged on the upper surface of the image display device 1. A signal for displaying “moving image 2” on the image output unit 20 a) is transmitted to the image display device 1.

  When the communication unit (not shown) of the image display device 1 receives a signal from the remote control 40, the control unit 39 switches the switching unit so that “moving image 1” is displayed on the first image output unit 10 (television). 37 is controlled. As a result, “moving image 1” is displayed on the first image output unit 10. Here, the first image output unit 10 displays any one of the moving images synchronized by the synchronizing unit 36.

  When a signal from the remote control 40 is received by a communication unit (not shown) of the image display device 1, the control unit 39 causes the second image output unit 20 (the front image 2) in which “moving image 2” is arranged on the upper surface of the image display device 1. The switching unit 37 is controlled so as to be displayed on the second image output unit 20a). As a result, “moving image 2” is displayed on the second image output unit 20a. Here, the second image output unit 20 displays other moving images other than the moving image displayed by the first image output unit 10 among the moving images synchronized by the synchronizing unit 36. That is, the second image output unit 20 displays a moving image in accordance with the switching of the switching unit 37 based on the control of the control unit 39. Each second image output unit 20 displays one moving image.

  Thereby, the moving image transmitted by the broadcast wave and the moving image transmitted via the Internet are displayed on the image output unit according to the user's preference among the first image output unit 10 and the second image output unit 20. Can be made.

  The speaker 38 outputs sound (sound) extracted from the moving image. When the speaker 38 is a surround speaker, the speaker that outputs sound may be changed according to the moving image displayed on the first image output unit 10 and the second image output unit 20. For example, when “moving image 1” is displayed on the first image output unit 10 (television), the speaker arranged in the image display device 1 outputs the sound of “moving image 1” with priority. Further, when “moving image 3” is displayed by the second image output unit 20 (left second image output unit 20c) disposed on the left side of the image display device 1, a speaker disposed on the left side with respect to the image display device 1 That is, the speaker arranged at a position near the wall on which the moving image 3 is displayed preferentially outputs the sound of “moving image 3”. Here, the control unit 39 controls switching of a sound (voice) signal output to the speaker 38.

  Further, the volume of the sound (sound) extracted from the moving image can be adjusted. That is, for example, the control unit 39 can adjust the volume of each moving image. More specifically, the control unit 39 adjusts the volume of the moving image sound received by the first receiving unit 31 and the volume of the moving image sound received by the second receiving unit 34, respectively. Output from the speaker 38.

  As an example, when the moving image 1 displayed on the remote control shown in FIG. 4 is selected by clicking, the volume of the moving image transmitted by the broadcast wave can be adjusted with the “volume” button on the remote control. In addition, when the moving images 2 to 4 displayed on the remote control are clicked and selected, the volume of the moving image transmitted via the communication network can be adjusted with the “volume” button on the remote control.

  Thereby, the user can hear the sound of the moving image based on the broadcast wave greatly, or can hear the sound volume of the moving image received via the communication network. As a specific example, when the video is soccer, the user listens to the explanation-centered sound received in the broadcast wave, listens to the sound of the audience seats, or kicks the ball or the player's You can hear a loud voice.

  The control unit 39 controls the image display device 1. As an example, the control unit 39 controls the first reception unit 31, the first synchronization buffer 32, the second synchronization buffer 35, the synchronization unit 36, the switching unit 37, and the request generation unit 33.

Further, in the image display device 1 as described above, it is preferable that the second image output unit 20 performs an enlarged display on the displayed moving image according to the sound level.
FIG. 5 is a diagram for explaining a moving image displayed on the image display device 1.
The sound (audio signal) is transmitted from the server 120 separately from the moving image, for example, or included in the moving image. The sound level is obtained based on the audio signal. The sound level represents the strength of the sound. For example, if the sound level is high, the sound is loud. The second image output unit 20 may perform enlarged display on the currently displayed moving image in accordance with a plurality of sound levels. The moving image to be enlarged is preferably high definition. That is, it is preferable that the moving image displayed in an enlarged manner is, for example, a Super Hi-Vision moving image. It is preferable that the center area of the enlarged display is determined in advance. It is preferable that the enlargement ratio when performing enlargement display is determined in advance.

Hereinafter, a specific first example will be described.
The second image output unit 20 (as an example, the previous second image output unit 20a) displays the entire moving image of the soccer field (see FIG. 5A). The sound is the sound of the cheering seat on one team side and the sound of the cheering seat on the other team side. When a player of one team performs a shot or the like, the cheering of one team is increased, and it is considered that the sound that is a criterion for performing enlarged display is increased. That is, it is considered that the sound level of the cheering seat on one team side becomes higher. On the other hand, when the player of the other team shoots or the like, the support of the other team side is increased, and it is considered that the sound that becomes the determination criterion when performing enlarged display is increased. That is, the sound level of the cheering seat on the other team side is considered to be high.

  Here, when a sound that is a determination criterion for enlarged display is included in the moving image and is received by the second receiving unit 34, the control unit 39 acquires the sound from the second synchronization buffer 35. That is, the control unit 39 acquires the sound of the cheering seat on one team side and the sound of the cheering seat on the other team side from the second synchronization buffer 35. And the control part 39 judges whether the level of each acquired sound became larger than the preset threshold value.

  When the sound level of the cheering seat of one team is higher than the threshold value, the control unit 39 determines that one team is invading, and the second image output unit uses the scoring scene of one team with great force. 20, the entire soccer field video displayed on the second image output unit 20 (previous second image output unit 20 a) is clipped, and the second image output unit 20 ( The image is displayed on the previous second image output unit 20a) (see FIG. 5B).

  On the other hand, when the sound level of the cheering seat of the other team is higher than the threshold value, the control unit 39 determines that the other team is invading and determines the scoring scene of the other team with great force. In order to display on the two-image output unit 20, the entire soccer field video displayed on the second image output unit 20 (previous second image output unit 20a) is clipped, and the second image is displayed near the goal of one team. The image is displayed on the output unit 20 (the previous second image output unit 20a).

The sound and the area to be clipped are associated in advance.
Thereby, the image display apparatus 1 can display a moving image so that presence may increase.

  In the image display device 1, when there are a plurality of second image output units 20, one main image output unit that preferentially displays a moving image for each of the plurality of second image output units 20, and a main image output Preferably, any one of the secondary image output units 20 other than the secondary image output unit 20 is set. In this case, the main image output unit displays one moving image selected according to the sound level from among the moving images displayed on each of the plurality of second image output units 20. The sub image output unit displays other moving images excluding the moving image displayed on the main image output unit among the moving images displayed on each of the plurality of second image output units 20.

  That is, when a moving image is displayed on each of the plurality of second image output units 20, the control unit 39 switches the switching unit 37 to switch the second image output unit 20 that displays a moving image according to the sound level. Control. A plurality of sounds (audio signals) are received by the second receiver 34. Alternatively, the sound is a sound included in a moving image displayed by the plurality of second image output units 20. The sound level is obtained based on the audio signal. The sound level represents the strength of the sound. For example, if the sound level is high, the sound is loud.

  The main image output unit is the second image output unit 20 that is most easily viewed by the user. That is, the main image output unit displays, for example, a moving image in front of the viewing user, and becomes the front second image output unit 20a. The sub image output unit is the second image output unit 20 that is less likely to be viewed by the user than the main image output unit. That is, the sub-image output unit displays, for example, a moving image on the side of the viewing user, and becomes the left second image output unit 20c and the right second image output unit 20b.

Hereinafter, a specific second example will be described.
The previous second image output unit 20a (main image output unit) displays the entire video of the soccer field, and the right second image output unit 20b (sub image output unit) displays the video near the goal of one team, and the left It is assumed that the second image output unit 20c (secondary image output unit) displays a moving image near the goal of the other team. The sound is the sound of the cheering seat on one team side and the sound of the cheering seat on the other team side. When a player of one team performs a shot or the like, the cheering of one team is increased, and it is considered that the sound that becomes the determination criterion when performing the switching display is increased. That is, it is considered that the sound level of the cheering seat on one team side becomes higher. On the other hand, when the player of the other team shoots or the like, the support of the other team side becomes large, and it is considered that the sound that becomes the determination criterion when performing the switching display becomes loud. That is, the sound level of the cheering seat on the other team side is considered to be high.

  Here, when the sound that is the determination criterion of the switching display is included in the moving image and is received by the second receiving unit 34, the control unit 39 acquires the sound from the second synchronization buffer 35. That is, the control unit 39 acquires the sound of the cheering seat on one team side and the sound of the cheering seat on the other team side from the second synchronization buffer 35. And the control part 39 judges whether the level of each acquired sound became higher than the preset threshold value. When the sound level of the cheering seat of one team is higher than the threshold value, the control unit 39 determines that one team is invading and causes the user to preferentially view the scoring scene of one team. In addition, a moving image near the goal of the other team is displayed on the second image output unit 20a (main image output unit), and a moving image of the entire soccer field is displayed on the second left image output unit 20c (secondary image output unit). Then, the switching unit 37 is controlled to display the moving image near the goal of one team on the second right image output unit 20b (secondary image output unit).

Next, a specific third example will be described.
The previous second image output unit 20a (main image output unit) displays the entire video of the soccer field, and the right second image output unit 20b (sub image output unit) displays the video near the goal of one team, and the left It is assumed that the second image output unit 20c (secondary image output unit) displays a moving image near the goal of the other team. The sound is the sound (sound) of a movie. That is, the sound of the moving image displayed on the front second image output unit 20a is the sound of the entire soccer field. The sound of the moving image displayed on the right second image output unit 20b is the sound near the goal of one team. The sound of the moving image displayed on the second left image output unit 20c is the sound near the goal of the other team.

  The control unit 39 generates a sound of the moving image displayed on the front second image output unit 20a, a sound of the moving image displayed on the right second image output unit 20b, and a moving image displayed on the left second image output unit 20c. Identify the sound that has the highest sound level. For example, when the control unit 39 specifies that the sound level of the moving image displayed on the left second image output unit 20c (secondary image output unit) is the highest, the left second image output unit 20c (secondary image output unit) The switching unit 37 is controlled so that the moving image displayed on the output unit) is displayed on the previous second image output unit 20a (main image output unit). Further, the control unit 39 switches the switching unit 37 so that the moving image displayed on the previous second image output unit 20a (main image output unit) is displayed on the left second image output unit 20c (sub image output unit). Control.

  Since the moving image displayed by the second image output unit 20a is displayed on the upper and rear surfaces of the image display device 1, it is considered that the user can easily view the moving image. For this reason, the image display apparatus 1 makes it easy for the user to view a characteristic moving image by replacing the moving image displayed on the previous second image output unit 20a (main image output unit) according to the sound level. Can do. That is, the image display device 1 can display a moving image so as to increase the sense of reality.

  The image display device 1 described above displays any one of the videos synchronized by the synchronization unit 36 on the first image output unit 10, and the videos synchronized by the synchronization unit 36 are displayed. Among them, other moving images except for the moving image displayed on the first image output unit 10 are displayed on the second image output unit 20. Both the first image output unit 10 and the second image output unit 20 are not tablet computers. For this reason, the image display apparatus 1 can make a user feel the force and presence of a moving image.

  Further, the second image output unit 20 performs enlarged display according to the sound level. Thereby, the image display apparatus 1 can display a moving image so that presence may increase.

  In addition, the main image output unit of the second image output unit 20 displays one moving image selected according to the sound level from among the moving images displayed on each of the plurality of second image output units 20. The sub image output unit of the second image output unit 20 displays other moving images excluding the moving image displayed on the main image output unit among the moving images displayed on each of the plurality of second image output units 20. By changing the moving image displayed on the second image output unit 20a (main image output unit) according to the sound level, the image display device 1 can display the moving image so as to increase the sense of reality.

  The first image output unit 10 is a television display. The second image output unit 20 is a projector. By using the second image output unit 20 as a projector, the image display device 1 can be made smaller than when the first image output unit 10 and the second image output unit 20 are both television sets. As a result, the image display apparatus 1 can display a large image even when placed in a relatively small room, and can make the user feel a sense of reality.

  In the above-described embodiment, the example in which the first image output unit 10 and the second image output unit 20 are arranged in the same housing has been described. However, the present invention is not limited to this example. That is, the second image output unit 20 may be removable from the casing in which the first image output unit 10 is arranged. The second image output unit 20 is disposed in a different housing from the housing in which the first image output unit 10 is disposed, and the image display device main body in which the first image output unit 10 is disposed, Alternatively, signals may be transmitted and received wirelessly. In such a modification, the degree of freedom of the second image output unit 20 increases, so that the possibility that the moving image projected on the wall by the second image output unit 20 is distorted can be reduced.

  In the above-described embodiment, the example in which the first image output unit 10 is a television display and the second image output unit 20 is a projector has been described. However, the present invention is not limited to this example. For example, the first image output unit may be a projector. The second image output unit may be a television display.
