  1.290 is a remote controller control unit, which scans the matrix of the key button unit 1.201, identifies the pressed key, assigns a key code, controls the distance measuring unit 1.240, and controls the TV device 1. 1 measures the distance between the remote control device and the data transmission / reception unit 1.202, communicates with the TV device 1.1, transmits various data such as the pressed key code information, distance measurement data, messages, operations, etc. Various types of data such as panels and icons are received, various types of information including the received data are displayed in 1.210, and the volume of audio data received by the audio receiving unit 1.220 is controlled.

The remote control device stores a remote control ID unique to the remote control in the control unit 1.290,
When transmitting the data, by transmitting the remote control ID prior to data transmission, it is possible to identify from which remote controller the remote control data is transmitted. In the present embodiment, the remote control ID of the remote control device 1.2 is “ID1”, and the remote control ID of the 1.3 remote control device is “ID2”.

  FIG. 4 shows external views of the two remote control devices 1.2, 1.3, and corresponds to FIG. 1.201po is a power key and is a key for turning on / off the TV apparatus 1.1. 1. 201sc is a screen key for adding and deleting screens.

  The TV apparatus 1.1 can display a screen of up to four screens within a designated screen area with one remote controller, and the rotation operation from one screen to four screens is performed according to the pressing of the screen key. Can be done. The displayed content is displayed based on the above-described display screen information, and a screen ID is assigned to the displayed screen.

  It is also used as a setting key for starting individual viewing by another remote control device. When there are other viewers, when the screen key is pressed by the other remote control, screen key processing and viewing area change processing described later are tracked. An area independent of other viewers is secured, and viewing of up to four screens and operation of the TV device 1.1 can be performed in this area. Note that a screen area is secured when starting display of a screen controlled by the remote control device (and power is turned on in some cases) and / or a screen area is deleted when display of the screen controlled by the remote control device is terminated. It is also possible to adopt a configuration in which a command for performing control for (and power OFF in some cases) is generated not by operating the screen key but by operating the power key as will be described later.

  1. 201 rs is a screen resize key. When the key is pressed during multi-viewing, distance measurement between the TV apparatus 1.1 and the remote controller is executed, and a viewing area changing process described later is performed based on the measured distance data. When activated, the screen size of the TV device 1.1 is reset.

  1.201 TV is a TV viewing basic key such as an input switching key, a channel selection key, and a volume key. 1.201mn is a TV expansion operation key such as a menu key, up / down / left / right cursor keys.

  Next, the operation of the present embodiment will be described with reference to the above and FIGS.

  First, some basic individual operations will be described.

  First, the operation on the remote control device side will be described with reference to FIG. 24 regarding the key transmission between the TV device 1.1 and the remote control devices 1.2 and 1.3 and the distance measurement in the present invention.

  The remote control device performs a key scan to detect key press by the remote control unit 1.290 (st2801).

  When the TV viewer presses the remote control button, key data corresponding to the button is generated and transmitted from the data transmission / reception unit 1.202 to the remote control control unit 1.140 of the TV apparatus 1.1. The key data includes the remote controller ID data of the remote controller, and the remote controller that transmitted the key data can be specified by the remote controller ID data (st2802).

  Next, the control waits for a response from the remote control unit 1.140 corresponding to reception of the transmitted key (st2803).

  If there is no response for a certain period of time, it is determined that an error process is to be performed, assuming that the pressed key is not normally received by the remote controller 1.140 (st2821).

  If there is no response even though the key code has been transmitted a predetermined number of times by the remote control device, an error is determined (st2821), error processing is performed, and the process is terminated. In the error processing, an error is displayed on the display unit 1.210 and an alarm is output to the audio output unit 1.230 so that the viewer can recognize that the pressed key has not been normally transmitted to the TV apparatus 1.1. (St2822).

  If it is determined that there is no error, the process returns to the key scan routine again (st2802).

  If there is a response, it is checked whether or not there is a distance data request in the response (st2803), and it is determined that the TV device 1.1 and the remote control device are facing each other, and a distance measuring unit 1.240 is obtained. The distance measurement between the remote control device and the TV device 1.1 is measured (st2807).

  Then, the distance data is transmitted from the data transmission / reception unit 1.202 to the remote control unit 1.140 of the TV apparatus 1.1 (st2809).

  Then, it waits for a response again (st2810). If there is a response, the process ends normally. If not, the error determination similar to st2821 is performed (st2841), and if an error is detected, error processing is performed (st2842). If not, the process returns to the key scan routine again, retransmits the distance data, and waits for a response from the remote control unit 1.140.

  Next, the control operation by the remote control device on the TV device 1.1 side will be described with reference to FIG.

  The remote control unit 1.140 of the TV apparatus 1.1 receives whether or not there is remote control key data. When data is received (st2101), it is first checked whether or not the power is on (st2102).

  If the power is off, check whether the received key data contains data corresponding to the command corresponding to the power key. If the key data does not contain data corresponding to the command corresponding to the power key, the power is turned off. The response is returned to the remote control device and the process is terminated (st2141, st2142).

  If the received key data includes data corresponding to the command corresponding to the power key even when the power is on or the power is off, the remote control ID of the data is checked and the RDC in the TV apparatus 1.1 is checked. It is investigated whether it is already registered in the table. If it is not registered, registration is performed (st2103, st2104).

  Thereafter, the key code is registered in the key buffer, and an event is generated for the listener of the key code (st2105).

  Then, it is checked whether or not the key data is key data including data corresponding to a command requiring a distance. This distance measurement necessity key is a power key, a screen key, a resize key, and a key registered in a distance measurement key table described later. The distance requirement table is as shown in FIG. 8, and is registered / released by an application program determined to require distance measurement, and is placed in the parameter storage unit 1.150 (st2106).

  If it is determined that distance measurement is not necessary, a distance measurement unnecessary response is returned as a response to the key reception (st2107).

  When it is determined that distance measurement is necessary, a distance data request response is transmitted to the remote control device 1.2 or 1.3, and distance data is received (st2121, st2122).

  If the distance data cannot be received for a certain period of time, an error is made based on the same processing as st2621 described above (st2131).

  If it is determined that an error has occurred, an error response is returned to 1.2 or 1.3 to the remote control device, and the process ends (st2131, st2132). If it is determined that there is no error, a distance request response is returned again (st2131, st2121).

  When distance data is received, a distance data reception response is returned (st2122, st2123), and the distance data is written in the distance data column of the corresponding remote controller ID in the RDC table (st2124).

  Next, the processing of the power key pressed by the viewer when the power is turned on / off and individual viewing ends will be described with reference to FIG.

  In the power key process, the key reception processing unit waits for a power key event to occur. If it is confirmed that the event is a power key event, it is checked whether the flag of the register in operation of the RDC table in the parameter storage unit 1.150 is set.

  If no flag is set in the operating register of the own remote controller ID that transmitted the key data or other operating registers other than the remote controller ID, the TV apparatus 1.1 is in the power-off state. It is determined that there is a power supply, and power ON processing is performed (st2202, st2211).

  After that, set the viewing flag of the operating register corresponding to the operated remote control ID of the RDC register, set the priority to “1 (highest priority)”, set the remote control distance, set the display area to the full screen, The screen display process is started and finished (st2211, st2212, st2213, st2214). Thereby, the screen area corresponding to the remote control device is set.

  When the operation register of the remote control ID that transmitted the key data is not set and any other operation register other than the remote control ID is set, the TV apparatus 1.1 transmits the key data. Since it is determined that the remote controller other than the remote controller is operated and the power ON / OFF process cannot be performed, the key invalid alarm process is performed (st2202, st2211, st2231). As in the example described later, a screen area corresponding to the remote control device may be set here, but in this embodiment, this function is not assigned to a command corresponding to the power key.

  If the flag of the in-operation register of the remote control ID that transmitted the key data is set, but no other in-operation register other than the remote control ID is set, the TV apparatus 1.1 is turned on. This is a state where the key data transmission remote controller is not operated (when no screen area other than the screen area controlled by the remote control device is set), and the power is turned off when the key is pressed. First, after clearing all the flags of the register in operation corresponding to the operated remote control ID and clearing the priority order, power off processing is performed to turn off the power of the TV apparatus 1.1 (st2202, st2203). , St2241, st2242, and st2243).

  When the operating register of the remote control ID that transmitted the key data and the other operating register other than the remote control ID are set, a screen area other than the screen area controlled by the remote control device is set. When the TV apparatus 1.1 is operating in the individual viewing mode with the power on, the TV apparatus 1.1 determines that the operation is to end the viewing by the viewer, and does not turn off the power. The screen area controlled by the device is deleted. In this case, the viewing flag and the priority order of the remote control for transmitting the key data are cleared, and the viewing area changing process described later is performed (st2202, st2203, st2205, st2206, st2207).

  Next, screen key processing that the viewer presses when starting the individual viewing screen will be described with reference to FIG. As described above, when the remote controller has already been operated, an operation for adding or deleting a screen is performed.

  The screen key processing unit waits for the occurrence of a screen key event from the key reception processing unit (st2301). If it is confirmed that the key is a screen key, it is checked whether or not the viewing flag of the in-operation register of the remote control ID whose key is pressed is set (st2302). It is determined that the key has been pressed by the remote controller that has not been operated, and a new individual viewing is being attempted, and a viewing area change process described later is started to set a screen area controlled by the remote controller (st2303). Here, simultaneously with the setting of the screen area, display of a screen on the screen area (display of a new screen) can be started.

  If it is set, it is determined that the screen mode has been changed by the remote controller that has already operated the screen, and screen addition / deletion processing is performed within the area corresponding to the operation remote controller ID. The process investigates the number of screen IDs in the corresponding area, and if the number of screens is less than 4, newly adds a screen ID and display screen information. If the number of screen IDs is 4, A process of clearing three screen IDs other than the current screen is performed (st2311).

  Then, it is investigated whether or not the distance of the remote controller ID has changed (st2312). If it has changed, a viewing area change process is performed (st2304). If it has not changed, the corresponding area is displayed on the screen. Processing is performed (st2313).

  Next, screen display processing will be described with reference to FIG.

  In the screen display process, first, the screen mode such as the number of screen IDs, two large and two small screens, two equal screens, and the main screen are investigated from the setting values corresponding to the remote controller ID in the RDC table (st2401, st2402, st2403). Based on the information, each screen size and start position are determined, written to the display screen information, and displayed based on the display screen information. Note that the screen mode and the main screen are changed by changing the screen mode through a menu operation (st2404).

  Then, the priority order is examined. If “1”, the main screen audio is output from the main screen TV 1.1 main body (st2408, st2409), otherwise, the audio transmission units 1.125a, b The voice is further transmitted (st2421).

  Next, viewing area change processing for adding / deleting individual viewing areas and changing and displaying a screen size necessary when the distance between the remote control device and the TV apparatus changes will be described with reference to FIG.

  First, the number n of viewing areas is determined from the number of viewing flags in the operating register or the menu flag described later (st2601), and then the priority order in which the viewing flags are set is reset in order from 1 (st2602). ).

  Next, in the case of adding a region, the screen ID of the display screen information of the remote controller ID operated in the RDC table is checked to check whether the screen is added. Are determined (st2603, st2604).

  At this time, if the previous information remains in the input information of the display screen item corresponding to the remote control ID operated in the RDC table, it is used (st2605). The lowest frequency channel of the tuner in use is set as an input source in the RDC table. The input information can be selected by another method (st2621).

  Next, the distance ratio Ri between each remote controller and the TV device is calculated based on the remote controller with the shortest distance from the distance data of the remote controller ID in which the register during operation is set, and this is determined in advance. It is investigated whether the distance ratio is within the maximum value Rmax (st2607).

  If it is within the range, the obtained distance ratio Ri is determined as the screen size parameter Pi (st2608), and if it is out of the range, the distance ratio maximum value Rmax is determined as the screen size parameter Pi. n-1 screen size parameters Pi are created for n areas (the same number of remote control devices and viewing flags in the operation register) (st2641).

And the ratio of the diagonal Di of the maximum screen that can be displayed in each of the n areas is
Each screen area and the maximum display screen size are determined so that P1: P2:...: Pn-1: 1 = D1: D2:. That is, the screen area and the display screen size increase as the viewer moves away from the TV device and the distance between the TV device and the remote control device increases.

  In addition, by setting the maximum distance ratio value, the display screen size is prevented from becoming extremely small when the distance between the TV apparatus and the remote control apparatus becomes small.

  It should be noted that the maximum screen that can be displayed in each area is a display of the aspect ratio of the display screen information set in the main screen in the display screen information of each area. By using the aspect ratio, the screen size considering the aspect ratio of the screen can be determined (st2609). Then, the above-described screen display processing is performed for each area, screen display is performed, and the process is terminated (st2610).

  Next, menu processing will be described with reference to FIG.

  Menu processing waits for the occurrence of menu-related key events.

  When a menu event occurs, it is checked whether or not the register being operated is set (st2702), and if it is set, it is determined that the display has already been made by the remote control device that generated the menu-related key event. Then, the process jumps to st2707 to display the menu screen by the menu related key event processing.

  If it is not set, it is determined whether the menu screen display in the menu key event processing can be displayed on the remote control device or whether it is necessary to display on the TV main body (st2703). Then, the menu flag of the in-operation register is set, and the other in-operation register performs the above-described viewing area changing process to secure the screen area (st2705, st2706). When the screen area can be secured, the menu screen is displayed.

  Here, it is checked whether there is one area where the register during operation is set (st2708). In one case, since the entire screen is displayed by one remote controller, the menu screen is displayed at the initial size and the initial position, and there is sound. In this case, the data is output from the TV main body (st2731, st2732).

  If there are multiple areas in which the register being operated is set, it is determined whether the menu screen size can be displayed within the area corresponding to the remote control ID being operated (st2708), and the size of the menu screen can be changed by changing the coordinates. If the display is possible without changing the coordinates, the coordinates are changed and displayed in the area, and whether the priority is “1” is checked. , Send the sound to the corresponding remote controller in operation (st2741, st2712, st2713, st2751). If the size cannot be displayed in the area, it is reduced to an appropriate size and appropriate coordinates are set and displayed in the area. (St2709, st2710). After setting a screen area corresponding to the remote control device, a menu screen as control information is displayed on the set screen region, so the menu screen is displayed in a screen area other than the screen area controlled by the remote control device. You can avoid that. Various other methods can be adopted as a method for avoiding that at least a part of the control information such as the menu screen is displayed in another screen area. In any case, the control information may be displayed by selecting a position where duplication to another screen area can be suppressed based on the coordinate data of each screen area.

  Then, in the same manner as described above, whether or not the priority is “1” is checked. If it is 1, audio is output from the TV body, and if it is not 1, audio is transmitted to the corresponding remote controller in operation (st 2712, st 2713, st2751).

  On the other hand, if it is determined in st2703 that the menu can be displayed on the remote control device, the menu screen is reduced for remote control display, and the display data is sent from the remote control unit 1.140. Then, it is transmitted to the remote control device performing the menu operation and displayed, and if there is sound, it is transmitted from the sound transmitting unit (st2721, st2722, st2723).

  When the display of the menu screen and the voice output control are completed, it is determined whether or not the menu process is terminated by the key process (st2715). If not, the corresponding key process is performed and the key process is terminated. Then, the next key event interrupt is awaited (st2716).

  When the key operation finishes menu operation or menu display, the menu flag in the register being operated is cleared, viewing area change processing is performed, if there is a display area, it is deleted, and other end processing is performed. Then, the menu process is terminated (st2761, st2762, st2763).

  Next, as a first operation example, the remote controller 1.2, 1.3 in which the viewer A at the distance “L1” from the TV apparatus 1.1 is different from the viewer B at the distance “L2”. Thus, the individual screen viewing operation of the TV apparatus 1.1 will be described. The distances L1, L2 are L1> L2, and the ratio L1 / L2 is within the distance ratio maximum value (Rmax).

  First, as shown in FIG. 9, when the viewer A who is at a distance “L1” from the TV apparatus 1.1 depresses the power button of the remote control apparatus 1.2 to turn on the TV apparatus 1.1, FIG. In accordance with the operation of FIG. 18, the remote controller ID, key data, and distance data are transmitted from the remote controller 1.2 to the TV apparatus 1.1.

  Next, according to FIG. 19, as shown in FIG. 6, in the RDC table, the distance of the remote controller ID1 is set to “L1”, the “viewing flag” in the operating register is set, and the “priority” is “1”. Set to area 1, and coordinates ((0, 0), (xend, yield)) for displaying the entire screen are set. The other values in the RDC table are the contents that were previously operated and held by the remote control device 1.2. Then, screen display is started in accordance with the screen processing of FIG. 21 described above, and viewing of the screen of tuner A BS192ch and screen aspect ratio of 16: 9 is started independently on the entire screen as shown in FIG. The sound is generated from the sound output unit 1.124 of the TV apparatus 1.1.

  Here, it is assumed that the viewer B presses a screen key of the remote control device 1.3 different from the remote control device 1.2 in order to perform individual viewing. Then, in the same manner as described above, the screen key data and the 1.3 remote control distance data are transmitted from the remote control device 1.3 to the TV device 1.1 in accordance with the operations of FIGS.

  Next, according to FIG. 20, as in area 2 of FIG. 7, the operation register of the remote control ID 2 of the RDC table is set to “viewing”. Then, other RDC table values are examined, and since “1” is set in the area 1, “priority” is set to “2”, the distance is set to the measurement data “L2”, and the viewing area changing process is performed. to start. The other values in the RDC table are contents previously operated and held by the remote control device 1.3. Thereby, the screen area controlled by the remote control device 1.3 is set.

  According to the viewing change process of FIG. 22 described above, the number of viewing areas is determined to be 2, and the priority order of audio is “1” for area 1 and “2” for area 2 from “priority order”, and area 2 is added. However, in the additional area 2, the display screen information of Tuner B, terrestrial wave 4ch, and screen aspect ratio 4: 3 that was displayed last time remains, and it is decided to display this.

Then, the distance ratio L1 / L2 is obtained from the distance “L1” and the distance “L2”. Since this is within the distance ratio maximum value (Rmax), the distance ratio is determined as the screen size parameter. , The ratio of the diagonal of the maximum display screen in the two areas is L1 / L2: 1 = D1: D2
Area 1 ((0, 0), (xe1, ye1)) and area 2 ((xs2, ys2), (xend, yield)) are determined so as to be equal to and written in the display area of the RDC table. Then, the display as shown in FIG. 10 is performed by the screen display process of FIG. 21 described above, and the sound of Tuner A of area 1 and display screen information 1 is output from the main body of the TV apparatus 1.1 as before, based on the voice order. Then, the sound of Tuner B in area 2 and display screen information 1 is transmitted from 1.125 to the remote control device 1.3.

  Next, as a second operation example, a case where the viewer B who is viewing individually moves from the distance L2 to the same distance L1 as the viewer A and presses the resize key of the remote control device 1.3 will be described. To do.

  When the resize key is pressed, the key data is received based on FIG. 24 and FIG. 18, it is recognized that the key is the resize key, the distance data request is made to the remote control device 1.3, and the remote control device 1. 3 measures the distance “L1” and transmits it to the TV apparatus 1.1. The TV apparatus 1.1 that has received the data writes the distance data in the field of the distance of the area 2 corresponding to the remote control ID 2 of the RDC table, and starts the viewing area changing process.

  In the viewing area changing process, the screen size parameter is recalculated without changing the screen contents. Based on this, the area is recalculated and the area coordinates are written. Based on the screen display process of FIG. 21, as shown in FIG. , Redisplay. In FIG. 11, the viewer B has moved away from the TV apparatus 1.1 as compared with FIG. 10, so the screen size of the viewer B has increased. On the other hand, when the viewer B approaches the TV apparatus 1.1, the screen of the viewer B becomes small. At this time, if the distance to the viewer A is more than a certain distance, or the distance ratio to the viewer A is equal to or greater than Rmax, the screen size does not become larger or smaller.

  As a third operation, a case will be described in which the viewer A presses a screen key and displays a plurality of screens in his / her area and area 1 in the state of the operation example 1.

  It is assumed that the screen mode is set to a large or small screen by a menu operation during previous viewing.

  When viewer A presses the screen key, key data reception and distance data reception are performed based on FIGS. 24 and 18 as described above, and then the RDC table is examined based on the screen key processing of FIG. As shown in FIG. 6, since the number of screen IDs in the operation remote control ID corresponding area is 1, screen ID 3 and its display screen information are newly added as shown in FIG. At this time, as the display screen information, the content of the display screen information 1 previously displayed, Tuner C, terrestrial wave 02ch, and screen aspect ratio 4: 3 are determined in the region 1, and the distance of the remote control does not change. Perform screen display processing.

  In the screen processing of FIG. 21, a small screen of TunerC is additionally displayed in the area 1 as shown in FIG. 12, based on the screen display information of the set screen ID3. Next, it is assumed that the viewer A performs a menu operation in the above state and changes the screen mode from the large / small two screens to the equivalent two-screen display.

  Then, based on FIGS. 24 and 18, key data reception and distance data reception are performed as described above. In the screen mode change operation process, the distance data and the changed mode are written in the screen mode of the RDC table, and the screen display process shown in FIG. 21 is started.

  The screen display process shown in FIG. 21 determines the sizes and positions of the display screens of the screen ID 1 and the screen ID 3 in the area 1 based on the changed screen mode of the two equal screens, and displays them as shown in FIG. . Thus, even if the screen mode changes, if the distance between the viewer A and the viewer B does not change, the respective areas do not change.

  Next, as a fourth operation example, when the viewer A presses the menu key of the remote control device 1.2 to perform the menu operation and / or the viewer B performs the menu operation of the remote control device 1.3. The display of the menu screen when the menu key is pressed will be described. The display screen when the menu key is pressed is such that some text with a frame as shown in FIG. 14 is selected by the cursor key and can be displayed on the remote control device.

  First, when the viewer A is performing single viewing on the entire screen by operating the remote control device 1.2, when the menu key is pressed, the in-operation register is set and the set screen area Therefore, according to FIG. 22, as shown in FIG. 14, the menu screen is displayed at the center of the screen with the initial size and position regardless of the screen mode.

  In addition, when viewing the entire screen of the viewer A, if the viewer B presses the menu key of the remote control device 1.3 in order to perform only the menu operation without pressing the screen key, the in-operation register is still set. Since there is no screen area, it can be displayed on the remote control device. Therefore, according to FIG. 22, a reduced menu screen is displayed on the remote control device as shown in FIG.

  In the individual viewing by the viewer A and the viewer B in FIG. 10, when the viewer A presses the menu key, the display register is set and the screen area is not one. Therefore, the remote controller operated by the viewer B It is necessary to avoid displaying the menu screen in the screen area controlled by the device. Here, if it is determined that the display can be performed without changing the initial size in the area of the viewer A, according to FIG. 22, the size is set to the coordinates in the area of the viewer A with the initial size as shown in FIG. Change and display in area A.

  On the other hand, when the viewer B presses the menu key, the display register is set, the screen area is not one, and it is necessary to avoid displaying the menu screen in the screen area controlled by another remote control device. Here, when it is determined that the display cannot be performed with the initial size in the area of the viewer B, the menu screen is reduced according to FIG. 22, and the coordinates are changed and displayed in the area of the viewer B.

  In the present embodiment, the menu display has been described only on the menu screen, but this can correspond to all displays as a result of operations by the operations of each viewer. For example, the operation panel of the connection device, channel display, volume display, warning message, icon, and the like.

  In the present embodiment, screen keys for adding a self-screen area at the start of individual viewing (screen area corresponding to a remote control operated by the user) and adding / deleting a self-screen area when displaying a plurality of self-screens are provided. Although provided, the function of adding / deleting the own screen area may be assigned to the power key without providing the screen key. As described above, when control is not performed so that a plurality of screens can be displayed in the screen area, addition or deletion of the screen area can be treated as equivalent to addition or deletion of the screen.

  FIG. 25 is a flowchart showing the operation of the TV apparatus 1.1 when the power key is pressed in the configuration in which the function for adding / deleting the self-screen area is assigned to the power key. Since operations other than st2220 and st2221 are the same as those described above (FIG. 19), description thereof will be omitted.

  When the power key is pressed by the remote controller 1.2 or 1.3, the self-screen corresponding to the remote controller in which the key operation has been performed is not displayed (the self-screen area is not set), and other screens (other remote controllers) (Screen controlled by operation) is displayed (the other screen area is set) (st2201 → st2202 → st2211), in st2220, the in-operation register and viewing for the remote control ID for which the power key was operated The flag is set and the viewing area changing process is started (st2221).

Control can be performed.

  In addition, although the structure which uses a some remote control device as an input device was illustrated as an example above, input devices other than remote control devices, such as an operation button provided in the housing | casing which accommodated the display control circuit (and display device) Can also be used. Further, in place of the control by the remote control device 1.3, when the display system performs a control for forcibly displaying a screen not based on the control of the viewer, the same control as the above by the remote control device 1.2 is performed. It is also effective when performing.

  As described above, in the embodiment described above, it is possible to provide a better individual screen viewing environment by determining the screen size based on the viewing distances between a plurality of viewers and the TV viewer.

  In addition, by setting the maximum distance ratio and providing an upper limit and a lower limit of the screen size, when the distance between the TV device and the remote control device is reduced, the display screen size is not extremely reduced.

  Further, by using the aspect ratio of the display contents when determining the screen area and the screen size, it is possible to determine the screen size considering the aspect ratio of the screen.

  In addition, by securing an area corresponding to the viewing distance of a plurality of viewers and TV viewers and performing OSD and menu display only within the secured area, the screens of other viewers who are viewing individually are displayed. It is possible to provide an environment that does not interfere.

  Further, by not displaying the menu screen that can be displayed on the remote control device on the TV device, it is possible to prevent the viewer from disturbing other viewers who are viewing individually.

  In addition, by giving priority to the audio output from the TV main body to the viewer who has started viewing first, it is possible to prevent viewing from being disturbed by the viewer who has started viewing first.

  Further, by turning off the power of the TV device by the power key only for the final viewer, it is possible to prevent the power from being turned off by an inadvertent operation and to provide a better multi-viewing environment.
