  FIG. 3 shows an essential part of the present invention shown in FIGS. Each block is denoted by the same reference numerals as those in FIGS.

  FIG. 4 is an explanatory diagram showing the operation of the apparatus of the present invention. Assume that the television receiver 100 is used to view still image (picture) or moving image (movie) data of the high-definition camera 200. First, as shown in Example A, mutual authentication between devices is performed to complete wireless connection.

  The high-vision camera 200 transmits display data (icon data) representing the function. Then, the display control apparatus 100 displays an icon indicating a function on the screen. In example A, the picture icon is shown on the left and the movie icon is shown on the right. This indicates that the high-vision camera 200 has a picture playback function and a movie playback function. Next, when the user moves the high-definition camera 200 to the left as shown in Example B1, the positional relationship between the high-definition camera 200 and the display control device 100 is analyzed by the previous position analysis unit 24.

  In this analysis, it is determined to which position the high-vision camera 200 has moved relative to the display control device 100 by determining the beam scanning operation and the reception status of the transmission signal from the high-vision camera 200.

  When the high-vision camera 200 moves to the position shown in Example B1, the control unit 11 transmits a command to the high-vision camera 200 so as to execute picture reproduction. Then, the high-vision camera 200 shifts to a picture playback mode, and transmits the picture content to be played back to the television receiving device 100 (display control device 100). The television receiving device 100 (display control device 100) executes a picture reproduction mode.

  Conversely, as shown in Example B2 of FIG. 4, when the high-vision camera 200 is moved, the positional relationship with the display control device 100 is analyzed by the previous position analysis unit 24. In this case, the moving image playback mode is entered. That is, the display control apparatus 100 analyzes the position of the high-vision camera 200 and transmits a command so as to perform operation reproduction. Then, the high-definition camera 200 shifts to a moving image playback mode and starts transmitting content. The display control apparatus 100 receives the content wirelessly and displays it on the display unit.

The wireless device used in the present invention includes an array antenna that allows a plurality of antennas having the same characteristics to be arranged and a beam to be directed in a desired direction using the phase difference in which excitation is shifted. For example, when three elements are arranged in a straight line at equal intervals and excited at half wavelength, the amplitude increases when the waves excited from each element overlap, and the beam does not overlap because the waves do not overlap in some places. In addition, there is a place where the beam is weakened by the influence of each wave. In the example of FIG. 5, a strong beam is formed in the top and bottom front direction. Here, an example in which there are three basic elements has been given, but using this characteristic, the mounting position of the antenna element, and excitation with shifted phases by mounting multiple elements, a more accurate beam Can be formed, and a beam directed to a wireless device with which communication is performed can be formed.

  For example, there is a wireless HD as a representative of a wireless communication system using a millimeter wave, and a fluctuation amount due to movement of a high-definition camera can be obtained by applying the above-described beam forming function of the wireless HD. The beam shape of the wireless communication path formed by moving the high-definition camera changes. By analyzing this, it is detected to which side the high-definition camera has moved, and an appropriate guide screen is displayed on the TV monitor (display unit). Can be provided to users. If the wireless device can emit a more accurate beam, it can provide the user with two or more options on the monitor.

  FIG. 6 shows a flowchart relating to the apparatus of the present invention. When wireless device A (television display control device 100) and wireless device B (high-vision camera 200) are communicating (step S1), an option (icon) with wireless device A is displayed on the monitor (step S2). . The user who sees it moves it from the currently installed position of the wireless device B in the direction of the desired option (icon) according to the screen display (step S3). The beam direction of the communication path is changed by the movement (step S4), and the change of the inclination of the beam direction, that is, the state of the phase difference is analyzed to determine which of the wireless devices B is relative to the wireless device A. (Step S5). That is, the arrangement relationship between devices is determined. If the analysis fails, the wireless device B is moved again to reanalyze the beam change (step S6). If the analysis is successful, the option selected by the user to the wireless device A in accordance with the moving direction of the wireless device B is output to the monitor and transmitted to the user (step S7).

  In the above description, user options are displayed as icons as shown in FIG. However, the present invention is not limited to this, and the user may be guided by voice. Of course, the user may be guided by both the voice and the monitor screen.

  Further, as shown in FIG. 7A, the arrangement position TV of the television display control apparatus 100, the position of options that can be selected by the user, the position B1, B2, and B3 of the picture playback mode, movie playback mode, and recording mode are shown. You may display on a plane.

  Here, for example, when the user selects a movie playback mode and this mode is set, a message and title number (or title name) for title selection (or chapter selection) as shown in FIG. May be displayed.

  The above example shows an example of the high-vision camera 200 and the television display control apparatus 100. However, the present invention is not limited to the high-vision camera 200, and may be a digital camera. Some recent digital cameras can record a short time movie in addition to taking a still image. Therefore, the present invention can be applied to this digital camera. The above-described wireless communication system may also be applied to game machines. Before starting the game, the present invention is applied until the television display control device automatically recognizes the game machine and selects the game type instead of the title as shown in FIG. 7B. It will be possible. Of course, the high-vision camera 200 may also be provided with a scan execution unit and a position analysis unit.

  As described above, according to the present invention, between devices used by wireless connection with each other, the operation mode between the devices is automatically determined by the device and device arrangement positional relationship, and the user simply determines the device arrangement relationship. What is necessary is just to determine according to a guide screen.
