  An embodiment of the present invention will be described below with reference to FIGS.

(Configuration of display device 1)
FIG. 1 is a block diagram showing a schematic configuration of a display device 1 according to an embodiment of the present invention. As shown in FIG. 1, a display device 1 includes a receiving unit (identification information receiving unit) 2, a content acquisition unit (content acquisition unit) 3, a content storage unit (content storage unit) 4, an image processing unit 5, and an image output unit. (Display means) 6, a display 7, an audio conversion unit (audio conversion means) 8, an audio output unit 9, a speaker 10, and a control unit 11.

  The display device 1 is a display device that can be operated by a plurality of different operation terminals 20. Specifically, when a control signal transmitted from the operation terminal 20 is received by a user operation, various operations are executed based on the control information included in the control signal. Further, the display device 1 can accept and operate a control signal transmitted from the other operation terminal 20 even when the user switches to another operation terminal 20.

  In addition, the display device 1 receives an operation signal from a plurality of different operation terminals 20 and switches the display of content according to each operation terminal. Specifically, when receiving the identification information transmitted from the operation terminal 20, the display device 1 acquires and displays content (display content) corresponding to the identification information.

  Here, the content is intended to be a content whose display form is switched in conjunction with the operation terminal 20 operated by the user, and includes, for example, operation information related to a method for operating the operation terminal 20. The display device 1 according to the present embodiment stores a plurality of contents including contents corresponding to identification information. Therefore, when receiving the identification information from the operation terminal 20, the display device 1 acquires content corresponding to the identification information from a plurality of contents stored in the display device 1 in advance.

  For example, when a user is viewing a television image on the display device 1 and displaying content representing the operation information of the operation terminal 20 currently used, the operation terminal 20 is switched to another operation terminal 20 for operation. Then, the content is switched to a content corresponding to another operation terminal 20.

  As described above, the display device 1 can be operated while confirming an operation method according to the currently used operation terminal 20 even if the user moves and operates a plurality of different operation terminals 20. Therefore, even when the user operates using a plurality of different operation terminals 20, an operation corresponding to the operation terminal 20 currently used can be easily performed.

  The receiving unit 2 receives the identification information transmitted from the operation terminal 20 and outputs it to the content acquisition unit 3.

  In this specification, the “identification information” is intended to identify the own device (operation terminal) that is held for each operation terminal 20. Therefore, the display device 1 displays content corresponding to the operation terminal 20 that transmits the received identification information. Thereby, even if it is a case where the operation terminal 20 currently used by the user is changed to another operation terminal 20 and operated, the display can be switched to the content corresponding to the other operation terminal 20. The identification information includes the type of operation terminal and the type information of the operation terminal, such as “TVRemoteControl / CellPhone / SH999”, which is expressed in a format such as “type of operation terminal / model information of operation terminal”. It may be information.

  The information communication method between the receiving unit 2 and the operation terminal 20 is not particularly limited, and short-range communication such as Bluetooth (registered trademark), wireless LAN communication, wireless USB, and infrared light may be used. . The receiving unit 2 receives control information transmitted from the operation terminal 20. Examples of the control information include channel or volume setting instructions.

  The content acquisition unit 3 acquires content corresponding to the received identification information. Specifically, the content storage unit 4 stores specific information for specifying each content in association with each of the plurality of contents. The content acquisition unit 3 acquires content associated with specific information that matches the received identification information.

  The content acquisition unit 3 can acquire the content from the external device 30 such as a server that distributes the content when the content corresponding to the received identification information is not stored in the content storage unit 4, for example.

  Further, the content acquisition unit 3 can acquire main content (other content) from the external device based on the control information transmitted from the operation terminal 20. The “main content” mentioned here means, for example, a television program acquired through an antenna, or various contents acquired through the Internet. Examples of the external device include a content distribution server, an antenna, an external storage device, and a recording medium. The content acquisition unit 3 outputs the acquired content and main content to the image processing unit 5.

  The content storage unit 4 stores a plurality of contents. Specifically, as described above, specific information for specifying each content is stored in association with each of the plurality of contents.

  The image processing unit 5 processes the content and the main content and outputs them to the image output unit 6.

  The image output unit 6 outputs the content processed by the image processing unit 5 and the main content to the display 7 at the same time. Thereby, the display 7 displays the content and the main content. The display 7 is realized as, for example, a liquid crystal display, a plasma display, or an organic EL display.

  The audio conversion unit 8 converts the display content of the content acquired by the content acquisition unit 3 into an audio signal. For example, when the content includes operation information, the user can use it more easily by converting the operation information like a voice guide. The audio conversion unit 8 outputs the converted audio signal to the audio output unit 9.

  The audio output unit 9 outputs the converted audio signal to the speaker 10. Thereby, the speaker 10 outputs the content as an audio signal.

  The control unit 11 performs overall control of operations in the display device 1.

(Operation by a plurality of operation terminals 20)
FIG. 2 is a diagram showing a flow of content acquisition according to the operation terminal 20 in the display device 1.

  In FIG. 2, the display device 1 is a TV, and acquires a TV program (main content) from the external device 30. 2 is operated by a remote controller 20A attached to the TV, a mobile phone 20B, a dictionary terminal 20C, and a plurality of operation terminals 20. Thus, the display device 1 can be operated by various mobile terminals in addition to the remote control attached to the TV. By operating the display device 1 using these operation terminals 20, for example, a TV program can be switched or an Internet service can be used on the TV.

(Content display switching example)
FIG. 3 is a diagram illustrating an example of switching contents displayed on the display device 1. Here, the user uses the Internet service, and “today's news” is displayed as the main content 21 on the display 7. In addition, on the display 7, for example, an operation guidance 22 such as an operation method for displaying the next news or an operation method for switching the genre of news is displayed as content.

  The operation guidance 22 varies depending on each operation terminal 20. Therefore, the operation guidance 22 to be displayed is switched according to the operation terminal 20 currently used by the user.

  First, the user operates the display device 1 using the remote controller 20A. At this time, the display device 1 recognizes that it is currently operated by the remote controller 20A. Therefore, as shown in FIG. 3A, the operation guidance 22 corresponding to the remote controller 20A is displayed on the display 7.

  Next, the user changes the remote control 20 </ b> A to the mobile phone 20 </ b> B, and transmits identification information to the display device 1 from the mobile phone 20 </ b> B. The identification information may be set in advance so as to be transmitted when the user presses a transmission button for identification information provided on the mobile phone 20, for example. The display device 1 changes the operation guidance 22 to be displayed based on the received identification information ((b) of FIG. 3). That is, in the display device 1, the operation guidance 22 corresponding to the remote controller 20A is switched to the operation guidance 22 corresponding to the mobile phone 20B.

  Furthermore, when the user switches from the mobile phone 20B to the dictionary terminal 20C and transmits identification information from the dictionary terminal 20C to the display device 1, the display device 1 receives the identification information of the dictionary terminal 20C. As shown in (c), the operation guidance 22 corresponding to the dictionary terminal 20C is displayed.

(Flow of content switching in the display device 1)
Next, a flow of processing from when the display device 1 receives the identification information to when content display switching is performed will be described. FIG. 4 is a flowchart showing a flow of content switching processing in the display device 1.

  First, the receiving unit 2 checks whether or not identification information is transmitted from the operation terminal 20 (step S1). When receiving the identification information, the receiving unit 2 notifies the control unit 11 that the identification information has been received (step S2). The control unit 11 confirms with respect to the content currently displayed on the display 7 with respect to the content storage unit 4 whether or not the content corresponding to the operation terminal 20 needs to be displayed (step S3).

  That is, the content storage unit 4 holds content based on the correspondence between the specific information and the identification information as shown in FIG. FIG. 5 shows a table for storing the content and specific information in the content storage unit 4 in association with each other.

  For example, when the user displays content on the display device 1, first, one of the common content that does not correspond to each operation terminal 20 (contents A to C) is displayed. Next, when the user transmits identification information from the remote controller 20A, the control unit 11 confirms whether the currently displayed content is content corresponding to the received identification information. As a result, when it is determined that the displayed content does not correspond to the received identification information, the control unit 11 further compares the received identification information with the specific information, and the content storage unit 4 performs the identification. It is confirmed whether or not the content A1 corresponding to the information is held (step S4).

  On the other hand, for example, when the content A1 is displayed, if the user further transmits identification information from the remote controller A1, the control unit 11 determines that the identification information corresponds to the currently displayed content A1, and the content This completes the switching process.

  Next, as shown in the column of specific information B in FIG. 5, when there is no content corresponding to the identification information, the control unit 11 determines that the content is not held in the content storage unit 4, and the content acquisition unit 3 The corresponding content is acquired from the server which is the external device 30 (step S5).

  The content acquisition unit 3 confirms whether the content corresponding to the identification information can be acquired from the server (step S6). As a result, if content acquisition from the server is possible, the content acquisition unit 3 acquires the content and stores the acquired content in the content storage unit 4 (step S7). The content acquired in this way is output by the image output unit 6 and displayed on the display 7 (step S8). On the other hand, if content acquisition from the server is not possible, the content switching process is terminated.

(Variation of identification information transmission method by operation terminal 20)
As described above, transmission of identification information by the operation terminal 20 is executed by giving a certain trigger to the operation terminal 20 such as a user pressing a button provided on the operation terminal 20. Here, a method of transmitting identification information by the operation terminal 20 is illustrated. FIG. 6 is a diagram illustrating a variation of identification information transmission by the operation terminal 20.

  For example, in the mobile phone 20B shown in FIG. 6A, the user interface 23 of the operation application of the display device 1 is displayed on the display screen. In this case, the user transmits the identification information by selecting the operation start icon 24 on the user interface.

  The remote controller 20A attached to the TV shown in FIG. 6B has an operation start button 25 as one of a plurality of buttons. In the remote controller 20A, when the user presses the operation start button 25, identification information is transmitted.

  Moreover, transmission of identification information can also be performed when the state of the operating terminal 20 changes.

  For example, as shown in FIG. 6C, a transmission button 26 may be provided on the back surface of the remote controller 20A. The transmission button 26 is normally provided so as to protrude from the back surface of the remote control 20A. However, when the remote control 20A is placed on a desk or the like, the transmission button 26 is pushed into the remote control 20A. When the user lifts the remote control 20A again, the transmission button 26 pops out. As described above, when the transmission button 26 is pushed out from the depressed state, the remote controller 20A determines that the user is using the remote controller 20A and transmits the identification information.

  In addition to this, as a method for transmitting identification information accompanying a change in state, for example, a sensor such as an acceleration sensor may be used. That is, the remote controller 20A may detect the “tilt” of the operation terminal 20 by an acceleration sensor provided in the operation terminal 20, and transmit identification information when the “tilt” exceeds a certain value.

  The display device according to the present invention may be used alone or in combination with an operation terminal that transmits identification information.
