  The terminal 501 or 502 can display menu image data and program guide image data on the screen of the touch panel, and the user operates the electronic device by touching an operation button displayed on the screen of the touch panel. A command signal can be given.

  FIG. 2 shows a configuration example of the terminal 501. The display 301 operates as a video display unit and can operate as a touch screen. When the user touches a desired item while the menu image is displayed, the operation input is recognized by the operation command processing unit 324 of the control unit 320. For example, when the touch operation is an operation input for selecting a telephone function, the operation mode setting unit 326 sets the terminal 501 to the mobile phone mode.

  The display 301 displays an operation screen for dial input. When a dial input operation of a desired destination is performed, the mobile phone function unit 325 transmits a call signal of the communication partner via the data processing unit 302, the communication control unit 303A, the transceiver 304A, and the antenna 305A. When the line with the communication destination is connected, a signal from the communication partner is decoded via the transceiver 304A, the communication control unit 303A, and the data processing unit 302. Audio data is output from the speaker 306. This audio data is processed by the data processing unit 302 via the microphone 307 and sent to the communication control unit 303A. Then, it is transmitted as transmission data to the communication partner via the transceiver 304A.

  The memory 321 is used for temporarily storing data or storing an application. Reference numeral 323 denotes a battery which can be charged.

  The terminal 171 can download content or an application via the Internet, for example. Further, the downloaded content or application can be transferred to, for example, the electronic apparatus shown in FIG. 1 based on the control of the data transfer unit 327. In this case, the terminal 171 functions as a repeater in appearance. Short-range communication is performed via the communication control unit 303B, the transceiver 304B, and the antenna 305B. The communication control units 303A and 303B, the transceivers 304A and 304B, and the antennas 305A and 305B may be integrated. And long-distance communication and short-distance communication may be switched according to transmission / reception mode. The terminal 501 may include a camera 308 and an image processing unit 328.

  The terminal 501 can download content from an external server or an electronic device and display the content on the display unit 301.

  FIG. 3 shows an example of a usage state of a plurality of terminals 501-504 that can communicate with the electronic device 100. The terminals 501 to 504 are held by the users 611 to 614.

  The electronic device 100 can grasp the managed terminals 501 to 504 by the short-range wireless communication system. Here, it is assumed that each user of the terminals 501 to 504 selects the TV communication mode as the operation mode.

  Then, as shown in FIG. 4, the electronic device 100 can secure a display area 511-514 that can display transmission data from the terminals 501-504 on the screen. In the figure, four display areas 511 to 514 for four terminals 501 to 504 are secured. However, if the terminal 504 does not select a TV communication mode, three display areas for three terminals 501 to 503 are displayed. Display areas 511-513 are secured.

  Also, the electronic device 100 can transmit identification data having different colors or different shapes to the terminals 501 to 504, for example. If the identification data is blinking data for display, blinking marks 521-524 are displayed on the display units of the terminals 501-504. On the other hand, identification marks 531-534 corresponding to the blinking marks 521-524 are also displayed in the display areas 511-514 of the electronic device 100. For example, the flashing marks 521 and 531 have the same shape or color, the flashing marks 522 and 532 have the same shape or color, the flashing marks 523 and 533 have the same shape or color, and the flashing mark 524 534 has the same shape or color. The identification mark 531-534 may be a model name of a corresponding terminal, a user name, or the like.

  Thereby, the user using each terminal can easily recognize the display area on the electronic device corresponding to his / her terminal.

  Next, it is assumed that the content 541 (moving image, data, or photographic image) is transmitted as “recommended information” or “interest information” from the terminal 501. Then, electronic device 100 displays content 541 in display area 511 corresponding to terminal 501. When the server address and the content ID are transmitted as “interest information” from the terminal 501, the electronic device 100 uses the received address. That is, the electronic device 100 can use the received address and content ID to access a server on the Internet, for example, and acquire the same content as the content 541 displayed on the terminal 501.

  Here, the user 611 who uses the terminal 501 may want other users 612 to 614 to share the same content 541. In this case, as shown in FIG. 5, the user 611 operates the terminal 501 or the remote controller 115 and operates the batch transfer button. Then, the operation command processing unit 202 detects the batch transfer command signal, and the communication control unit 203 transfers the address and content ID necessary for acquiring the same content 541 or the same content 541 to each terminal 502-504. .

  At this time, the terminals 502 to 504 may return the content 541 to the electronic device 100 in order to notify the reception. As a result, the content 541 is also displayed in the display areas 512-514. As a result, the user 611 can confirm that the terminal 502-504 of the user 612-614 has received the content.

  In this case, the identification between the transmitting side and the receiving side is displayed in the display areas 511 and 512-514. There are various methods for identifying the transmitting side and the receiving side. For example, “Sent” or “OUT” may be displayed below the display area 511, and “Received” or “IN” may be displayed below the display areas 512, 513, 514. In other words, it is possible to display the notification of being the sending side and the receiving side.

  The trigger for distributing the content 541 or the address and content ID necessary for acquiring the content 541 from the electronic device to the terminals 502 to 504 is not limited to the above description. The electronic device may automatically start requesting information on the content displayed in the terminal 501 in a predetermined mode.

  In FIG. 6, the above operation process is shown by a left block arrangement, and the transmission / reception directions between the terminals and the electronic device 100 are shown on the right side.

  For example, the electronic device 100 requests information necessary for acquiring information on the content displayed on the terminal 501 (interest information such as an address and a content ID) (steps SA1, SA2, and SA3). The terminal 501 transmits the interest information to the electronic device 100 in response to the request. The electronic device 100 grasps the status of the other terminals 502-504 that are currently connected by polling (steps SA4 and SA5). If terminal 502-504 can accept the content, electronic device 100 transmits the interest information to terminal 502-504 (step SA6).

  Thereby, each terminal 502-504 can access the server using the interest information (address and content ID), and can acquire the same content as the content being viewed on the terminal 501.

  Prior to transmitting the content to each terminal 502-504, electronic device 100 may transmit data or an application or an encryption / decryption key necessary for processing the content to each terminal 502-504. . Thereby, even if the content is encrypted and transmitted, each terminal 502-504 can easily decrypt the content. Each terminal 502-504 can receive and store game software and the like.

  Various modifications can be made to the above-described embodiment. For example, a content reacquisition function, a content comparison function, a game processing function, and the like may be established in the control unit 200. For example, the CPU 201, the memory 212, the operation command processing unit 202, the display processing unit 211, the communication control unit 203, and the operation device management unit 204 are integrated to construct these various functions. Alternatively, a dedicated functional block may be provided in the control unit 200.

  For example, it is assumed that the content itself is transferred from the terminal 501 to the electronic device 100. In this case, since the electronic device 100 has a larger screen than the screen of the terminal 501, the image quality is better when the content with high resolution is displayed. In such a case, the electronic device 100 may request the terminal 501 for the address of a server that acquires content based on the control of the content re-acquisition function, and acquire high-resolution content from the server. it can. For example, reading data, animation content, and the like can be viewed with high-quality video by reproducing high-resolution content.

  The electronic device 100 has a content transfer function. However, when transferring content to the terminals 502 and 503, the electronic device 100 can transfer content with low resolution. For example, if the content to be transferred is a low-resolution content acquired from the terminal 501, the content is transferred as it is to the terminals 502 and 503. Alternatively, the content is converted into a resolution and size suitable for the resolution of the terminals 502 and 503 and transferred.

  The electronic device 100 has a large screen, and the terminals 501 to 504 have a small screen. For example, it is assumed that the users 611 to 614 acquire moving images or still images by using the camera functions of the terminals 501 to 504, respectively. At this time, the users 611-614 can transfer the moving images or still images of the terminals 501-504 to the electronic device 100, respectively. The electronic device 100 can display the received moving image or still image on the display area 511-514 and present it to all users.

  At this time, if there is a desired moving image or still image, the user 611-614 can also capture it in his / her terminal. For example, the terminal is set to a content capturing mode from an electronic device. Then, the cursor (or a blinking mark may be used) on the screen of the electronic device 100 is moved to set the content image (display area of another user) of another user. Next, desired content can be captured from the electronic device 100 by touching the capture button.

  In addition, in a state where the moving image from each terminal 501-504 is displayed in the display area 511-514, for example, the synchronization display button may be operated on any terminal. In this case, the terminal 511-514 can adjust the start frame of the moving image displayed in the display area 511-514. For example, when the frame advance button or the reverse feed button of the terminal 511-514 is touched, the image in the display area 511-514 can be frame-by-frame fed or reversely fed. By this operation, the start screen of the moving image displayed in the display area 511-514 is set. Next, when the synchronous display button of any terminal is operated, the moving images displayed in the display areas 511-514 are displayed in synchronization. For example, it is effective when checking a moving image obtained by imaging the same subject from different angles. It is also effective when checking moving images taken of different subjects in the same time zone. The terminal can also be a movie camera.

  It is also possible to store game applications in the electronic device 100 and the terminals 501-504. In this case, a game screen is displayed on the electronic device 100, and a plurality of users can operate the operation buttons of the terminals 501 to 504 to enjoy the game. Further, a game screen may be displayed on the terminals 501 to 504 and an operation screen may be displayed. As for the progress of the game, the operation command on the operation screen of a certain terminal is operated on the touch-type panel, whereby the next command signal and game change signal are transmitted to the other terminals, and the game progresses. In this case, a transmission / reception signal between terminals may be transmitted / received via an electronic device, or may be transmitted / received between terminals. When the electronic device functions as a simple relay device, a user who is watching a program that is the electronic device does not appear on the screen as a result of the game being executed.

  The embodiment of FIGS. 3 and 4 is an example in which the terminals 501 to 504 are present in the short-range wireless communication area of the electronic device 100. However, the present invention is not limited to this embodiment.

  FIG. 7 shows another embodiment. Now, assume that the user 600 operates the terminal 500 and transmits a problem to the terminals 501 to 504 of the students 601 to 604. The students 601 to 604 operate the terminals 501 to 504 to send back answers to the terminal 500.

  In this case, the terminal 500 can secure a display area for each of the terminals 501 to 504 in the same manner as the example of the previous electronic device, and the user 600 can see the response from each of the terminals 501 to 504. However, securing a plurality of display areas on the screen of the terminal 500 and checking an answer may cause the display area to be too small.

  Therefore, the user 600 can transfer the contents of the terminal 500 to the electronic device 100 and check the responses from the terminals 501 to 504 while comparing them on a large screen. Note that responses from the terminals 501 to 504 may be directly transmitted to the electronic device 100.

  Although several embodiments of the present invention have been described, these embodiments have been presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
