At this time, each time the CPU 15 receives a display switching instruction transmitted from the remote controller 20 and indicating that the display switching button has been pressed, the CPU 15 selects one of the display patterns stored in the memory 16 and selects the remote controller 20. Send to.

Further, when there are a plurality of information contents displayed on the display unit 17, the CPU 23 may receive all the information contents, generate a plurality of information content display patterns in advance, and store them in the memory 24. . At this time, every time the display switching button is pressed, the CPU 23 selects one from the display patterns stored in the memory 24 and displays it on the information display unit 25.

Further, when the information content displayed on the information display unit 25 includes selectable options, the CPU 23 of the remote controller 20 operates an arrow key and a selection button provided on the operation unit 22. The user instruction performed by is accepted as a selection instruction. In addition, the CPU 23 transmits the selection instruction received in the operation unit 22 to the television 10 via the communication unit 21. When the selection instruction transmitted from the remote controller 20 is received via the communication unit 14, the CPU 15 of the television 10 transmits the selection selected by the remote control 20 to the external network via the external network communication unit 13 as a selection command. .

Information content often has character string information as main information as compared with video content. Therefore, when it is displayed on the display unit 17, it may be difficult for a user such as myopia and presbyopia to see the information content. . However, as described above, by displaying the information on the information display unit 25, the information content can be displayed at the user's hand, so that the user's inconvenience that it is difficult to see can be reduced.

In the present embodiment, the case where information content is displayed on the information display unit 25 has been described as an example, but the present invention is not limited to this. For example, when the above-described transmission setting information or transmission instruction information indicates a setting for transmitting a partial moving image of video content, a still image of video content, or the like included in broadcast content to the remote controller 20 These contents may be transmitted. In this case, a part of the video content included in the broadcast content, a still image of the video content, and the like may be displayed on the information display unit 25.

Further, when displaying a part of moving image, still image, etc. of the video content on the information display unit 25, the CPU 15 may extract an image to be displayed on the information display unit 25 from the video content.

Note that the video display device according to the present invention is not limited to the television 10. For example, the video display device may be an HD recorder that includes a display unit outside and can receive broadcast content, a personal computer (hereinafter also referred to as a personal computer), and the like. That is, the HD recorder that is the video display device according to the present embodiment only needs to include a display unit outside and a configuration other than the display unit 17 among the configurations included in the television 10 described above. Note that, for example, a configuration in which the HD recorder and the external display unit are connected using an HDMI terminal, a composite terminal, or the like can be given as an example, but the present invention is not limited to this.

In addition, the broadcast content has been described as an example of the display content received from the outside, but the present invention is not limited to this, and is, for example, content broadcast by cable broadcasting typified by CATV. May be. The display content received from the outside may be content input from a DVD player / recorder, BD player / recorder, HD recorder, or the like, or content that is streamed and distributed by the VOD system on the Internet. Also good.

When the broadcast content is content broadcast by cable broadcasting represented by CATV and content streamed on the Internet, the video content is, for example, a moving image, a still image, and Any image that is a combination of a moving image and a still image may be used. The information content includes a file described in a markup language (for example, SMIL (Synchronized Multimedia Integration 静止 Language)), a still image and character string information displayed when the “d” button in FIG. 1 is pressed. And so on.

When the display content received from the outside is broadcast content by cable broadcasting, the broadcast content is received via a set-top box connected to a connection unit included in the television 10. When the display content received from the outside is content that is streamed, the CPU 15 plays back the content that is streamed using streaming playback software.

Furthermore, in the present embodiment, the case where the information display device is the remote controller 20 has been described as an example. However, the present invention is not limited to this, and reception and display of information content to be displayed at the user's hand. A terminal device other than the remote controller 20 that can be used may be used.

This makes it possible to configure an information display device using a device that the user usually places close to him / her.

In the present embodiment, when the information content includes selectable options, that is, when the broadcast content is viewer-participatory interactive content, the option selected by the remote controller 20 is used as a selection command. Although the configuration of transmitting to an external network via the external network communication unit 13 included in the television 10 has been described as an example, the present invention is not limited to this.

<Modification>
A modification of this embodiment will be described with reference to FIG. For convenience of explanation, components having the same functions as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted. In the present embodiment, differences from the first embodiment will be mainly described.

FIG. 7 is a block diagram showing the configuration of the remote controller 20a according to this modification. As shown in FIG. 7, the remote controller 20 a has the same configuration as the remote controller 20 of the first embodiment except that it includes an external network communication unit (third communication unit) 26. Note that the television according to this modification has the same configuration as the television 10 in the first embodiment.

The external network communication unit 26 is a means for transmitting a user participation command to the external network when the broadcast content is a viewer participation type interactive content. Specifically, the external network communication unit 26 includes a plurality of pieces of information that can function as options that can be selected by the user on the remote control 20a (for example, interactive content in which the broadcast content is a viewer participation type). ), The option selected by the user is transmitted to the external network as a user participation command.

As the interactive content, for example, a quiz program can be cited, and the options that can be selected by the user can include, for example, an option for answering a quiz program.

Since the remote controller 20a includes the external network communication unit 26, the selected option can be transmitted as a selection command to the external network via the external network communication unit 26 without using the television 10.

Note that the television 10 in the present modification may or may not include the external network communication unit 13. When the external network communication unit 13 is provided in the television 10, the selected option is transmitted as a selection command to the external network via the external network communication unit 13 provided in the television 10, or the external device provided in the remote controller 20 is provided. Whether to transmit to the external network via the network communication unit 26 may be determined by a user instruction.

According to the above configuration, when the broadcast content is a viewer participation type interactive content such as a quiz program, the option selected by the remote controller 20 can be transmitted to the external network without going through the television 10.

<Embodiment 2>
Next, another embodiment of the present invention will be described with reference to FIGS. For convenience of explanation, components having the same functions as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted. In the present embodiment, differences from the first embodiment will be mainly described.

(TV configuration)
FIG. 8 is a block diagram showing the configuration of the television 10 ′ according to this embodiment. As shown in FIG. 8, the television 10 ′ according to the present embodiment has the same configuration as the television 10 of the first embodiment except that the television 10 ′ includes a character recognition unit 19 (character recognition means).

When the character recognition unit 19 receives broadcast content in which a character string is superimposed on the video content included in the broadcast content received by the antenna 11 (so-called superimpose), the character recognition unit 19 extracts the character string from the broadcast content. The character recognition unit 19 transmits a character string extracted from the broadcast content as information content to the remote controller 20 via the communication unit 14 under the control of the CPU 15.

Note that, when the video content included in the broadcast content is a three-dimensional moving image, the character recognition unit 19 extracts the superimposed character string as a two-dimensional image.

The CPU 15 controls the character recognition unit 19 to transmit the character string extracted by the character recognition unit 19 as information content to the remote controller 20 via the communication unit 14.

When the display content received from the outside is broadcast content, for example, a movie that is wirelessly broadcast from a broadcasting station, the character string superimposed on the video content may include, for example, a caption subtitle in the movie Can do.

[Operation of display system]
The operation of the display system 1 according to the present embodiment will be described with reference to FIG. FIG. 9 is a flowchart showing a flow of information content display processing on the information display unit 25 provided in the remote controller 20 of the display system 1 according to the present embodiment. In FIG. 9, a broadcast content in which a character string is superimposed on video content will be described as an example of the broadcast content received by the antenna 11.

As shown in FIG. 9, first, the television 10 'receives broadcast content at the antenna 11 (step S21).

When the broadcast content is received, the character recognition unit 19 determines whether a character string is superimposed on the video content included in the broadcast content (step S22).

If it is determined that the character string is not superimposed on the video content (NO in step S22), the character recognition unit 19 notifies the CPU 15 that the character string is not superimposed on the video content. The CPU 15 having acquired the notification displays the video content received by the antenna 11 on the display unit 17. The character recognition unit 19 and the CPU 15 repeat the operations of steps S21 and S22 until the character recognition unit 19 determines that the character string is superimposed on the video content.

When it is determined that the character string is superimposed on the video content (YES in step S22), the character recognition unit 19 recognizes an area where the character string is superimposed on the video content (step S23). Specifically, the character recognition unit 19 recognizes in which area of the display unit 17 the character string is displayed when the video content is displayed on the display unit 17.

In addition, since the caption super is generally displayed in the lower end area, the left end area, or the right end area of the display unit 17, the recognition of the area where the character string is superimposed in the character recognition unit 19 is It is preferable to target only these regions and not the central region. Thereby, the speed of the process related to the recognition of the character string in the character recognition unit 19 can be improved.

When recognizing the region where the character string is superimposed, the character recognition unit 19 extracts the character string included in the recognized region (step S24). A method for extracting a character string will be described later.

When the character recognizing unit 19 extracts the character string from the region where the character string is superimposed, the character recognizing unit 19 transmits the extracted character string as information content to the remote controller 20 via the communication unit 14 under the control of the CPU 15 (step S25). ).

When transmitting the information content to the remote controller 20, the character recognition unit 19 determines again whether a character string is superimposed on the video content included in the broadcast content received by the antenna 11. That is, the television 10 'repeats the operations from step S21 to S25 as long as it continues to receive broadcast content.

(Character string extraction method)
Next, a method for extracting a character string in the character recognition unit 19 will be described. Here, two types of character string extraction methods will be described, but the present invention is not limited to this.

When the character recognition unit 19 recognizes the region where the character string is superimposed, the character recognition unit 19 first extracts the character string from the superimposed region and recognizes what character string the character string is. The character recognition unit 19 converts the recognized character string into text data, and sequentially transmits the character code of the converted text data as information content to the remote controller 20 via the communication unit 14 under the control of the CPU 15.

In this extraction method, since the character string superimposed on the video content is extracted by the character recognition unit 19, the television 10 ′ can also delete the character string from the video displayed on the display unit 17. This is particularly effective when the video content is a 3D video. This is because in a 3D image, a character string without the concept of depth will appear floating in the 3D image, resulting in an unnatural display and very difficult to see.

Therefore, by displaying the character string superimposed on the video content extracted in the character recognition unit 19 on the information display unit 25 and deleting the character string from the video displayed on the display unit 17, the character string is easy to see, and You can enjoy more natural images. The character string extraction method described above is particularly suitable when the processing speed of the television 10 'is sufficiently high.

Further, instead of transmitting the extracted character string as information content, the character recognition unit 19 may transmit an area where the character string is superimposed as information content. Specifically, when the character recognition unit 19 recognizes the region where the character string is superimposed, the character recognition unit 19 extracts the region from the video content as a still image, and uses the region data including the extracted character string as the information content on the remote controller 20. Send to.

Such a character string extraction method is particularly suitable when the communication speed between the TV 10 'and the remote controller 20 is sufficiently high, although the processing speed of the TV 10' is not sufficiently high. Therefore, the television 10 ′ may select an optimum method from the above-described two character string extraction methods based on the processing speed of the television 10 ′ and the communication speed between the television 10 ′ and the remote controller 20. .

It should be noted that the character string superimposed on the video content as a subtitle supermarket is often the same character string over a plurality of frames constituting the video content. Therefore, the character recognition unit 19 does not need to perform the above-described character string extraction, recognition, and transmission processing for each frame of the video content. It may be performed only when the character string is changed to a different character string.

In the present embodiment, the case where the display content received from the outside is a broadcast content has been described as an example, but the present invention is not limited to this. For example, the content may be content input from a DVD player / recorder, a BD player / recorder, an HD recorder, or the like, or may be content streamed by the VOD system on the Internet.

In the present embodiment, the configuration has been described in which the character string superimposed on the video content is extracted simultaneously with the display of the video content included in the received broadcast content, and transmitted as information content. However, the present embodiment is limited to this. It is not a thing. For example, display of content input from a DVD player or the like is different from display of broadcast content, and it is not necessary to display video content and extract a character string simultaneously with reception on the television 10 ′.

When the display content is content input from a DVD player, a character string superimposed on the video content is extracted in advance, and when a certain character string is extracted, display of the video content and information Content transmission can be started. When the display content is content input from an HD recorder, a character string superimposed on the video content can be extracted in advance, and the extracted character string can be stored in the HD.

Thereby, the display of the video content on the display unit 17 included in the television 10 ′ and the display of the information content on the information display unit 25 included in the remote controller 20 can be performed with almost no time difference.

Note that the video display device according to the present invention is not limited to the television 10 ', and includes, for example, a configuration other than the display unit 17 among the configurations provided in the television 10' described above. Or an HD recorder. Note that, for example, a configuration in which the HD recorder and the external display unit are connected using an HDMI terminal, a composite terminal, or the like can be given as an example, but the present invention is not limited to this.

Furthermore, the information display device according to the present invention is not limited to this, and for example, a terminal device other than the remote controller 20 that can receive and display information content to be displayed at the user's hand may be used. As the terminal device, for example, a mobile phone, a smartphone, a PDA, a personal computer, and the like provided with the configuration of the remote controller 20 described above can be given as examples.

As a result, it is possible to reduce the burden of processing related to communication in the television 10 ″.

Further, when the broadcast content is a program using two-way communication, it is not preferable to accept an operation from all of the plurality of remote controllers 20 ". For example, the broadcast content is a viewer participation type quiz program. In this case, when a different answer selection instruction is received from each of the remote controllers 20 ″ a to 20 ″ c, the television 10 ″ cannot determine which selection instruction is selected as an answer in the display system 2. .

In such a case, the CPU 15 included in the television 10 ″ determines only one of the selection instructions from the remote controllers 20 ″ a to 20 ″ c received by the communication unit 14 as the selection in the display system 2. Specifically, the CPU 15 displays the display by referring to the selection setting information stored in advance in the memory 16 as to whether the selection instruction received from which remote controller 20 ″ is determined as the selection instruction in the display system 2. What is necessary is just to determine as selection in the system 2.

In addition, the display system 2 according to the present embodiment may be configured such that a selection operation can be performed only on any one of the remote controllers 20 ″ a to 20 ″ c. First, the CPU 23 provided in each of the remote controllers 20 ″ a to 20 ″ c refers to operation setting information stored in advance in the memory 24 as to whether or not a quiz program answer selection operation is possible. Only when the selection operation is possible based on the setting information, the user's selection operation may be accepted and transmitted as a selection instruction to the television 10 ″ via the communication unit 21.

When the CPU 15 included in the television 10 ″ receives a selection instruction from any one of the remote controllers 20 ″ a to 20 ″ c, the CPU 15 ″ uses the option indicated by the selection instruction as a selection command via the external network communication unit 13. Send to the network.
