When the determination result of step SB5 is “NO”, the control unit 15 proceeds to step SB6. In step SB6, the control unit 15 determines whether or not the incoming call detection signal RD1 is supplied from the incoming call detection circuit 12. When the determination result of step SB6 is “NO”, the control unit 15 returns to step SB5. When the incoming call detection signal RD2 is supplied from the incoming call detection circuit 12, the determination result in step SB5 is “YES”, and the control unit 15 proceeds to step SB7.
In step SB7, the control unit 15 determines whether the telephone number data DN2 or the mail address data MA is supplied from the telephone number / mail address detecting circuit 13. When the determination result of step SB7 is “NO”, the control unit 15 repeats the determination. When the telephone number data DN2 or the mail address data MA of the portable terminal 3 is supplied from the telephone number / mail address detection circuit 13, the determination result in step SB7 is “YES”, and the control unit 15 supplies The telephone number data DN2 or mail address data MA is supplied to the encoder 16.

When the incoming call detection signal RD1 is supplied from the incoming call detection circuit 12, the determination result in step SB6 is “YES”, and the control unit 15 stores its own device stored in a predetermined storage area of the storage unit 18. The telephone number data DN1 of the telephone number assigned to is supplied to the encoder 16.
As a result, the encoder 16 encodes its own telephone number data DN1, telephone number data DN2 or mail address MA supplied from the control unit 15, and supplies the encoded signal EC to the wireless communication unit 17 (step SB8). ). Accordingly, the wireless communication unit 17 performs modulation using the encoded signal EC supplied from the encoder 16, transmits the modulated signal VE from the antenna 23, and ends the series of processes (step SB9).

Next, among the operations of the video display apparatus 2 having the above-described configuration, operations related to incoming call display, which is a feature of the present invention, will be described with reference to the flowchart shown in FIG. In the video display device 2, the receiver 39 determines whether or not the modulation signal VE has been received in a state where the power is turned on (step SC1). When the modulation signal VE is received, the determination result in step SC1 is “YES”, and the receiver 39 demodulates the encoded signal EC from the modulation signal VE received by the antenna 38 and supplies it to the decoder 40 ( Step SC2).
The decoder 40 supplied with the encoded signal EC decodes the telephone number data DN1, DN2 or the mail address data MA from the encoded signal EC and supplies it to the control unit 34 (step SC3).

The control unit 34 to which the telephone number data DN1, the telephone number data DN2 or the mail address data MA is supplied refers to the registration table shown in FIG. 4 and the telephone number data DN1, DN2 or the mail address data supplied from the decoder 40. It is determined whether or not the MA is registered (step SC4). If the determination result in step SC4 is “NO”, that is, if the telephone number data DN1, DN2 or the mail address data MA supplied from the decoder 40 is not registered, the control unit 34 does nothing, Terminate the process.
On the other hand, if the determination result in step SC4 is “YES”, that is, if telephone number data DN1, DN2 or mail address data MA is registered, control unit 34 proceeds to step SC5. In step SC5, the control unit 34 refers to the registration table shown in FIG. 4 to determine whether the incoming display method of the telephone number data DN1, DN2 or mail address data MA is the lighting of the LED 44. If the determination result in step SC5 is “YES”, that is, if the incoming call display method is to turn on the LED 44, the control unit 34 proceeds to step SC6.

In step SC6, the control unit 34 refers to the registration table shown in FIG. 4, and a control signal for continuously lighting or blinking the LED 44 with the color registered for the telephone number data DN1, DN2 or the mail address data MA. After SC2 is generated and supplied to the LED drive circuit 43, the process proceeds to step SC7. Thereby, the LED drive circuit 43 applies the drive voltage DV to the LED 44 based on the control signal SC2 supplied from the control unit 34. For example, as shown in FIG. 1, when there is an incoming call from the master unit 1, the LED 44 provided at the lower right portion of the video display device 2 is continuously lit in red.
In step SC7, the control unit 34 determines whether or not the supply of the modulation signal VE has been stopped. This determination is made based on whether or not the reception level signal RE supplied from the receiver 39 is not supplied when the input voltage of the modulation signal VE is equal to or higher than a predetermined voltage. If the determination result in step SC7 is “NO”, the controller 34 returns to step SC6 and continues to supply the control signal SC2. Thus, as long as the reception level signal RE is supplied from the receiver 39 to the control unit 34, the LED 44 continues to be lit continuously or blinking in a predetermined color.

  On the other hand, if the determination result in step SC7 is “YES”, that is, if the supply of the modulation signal VE that has been supplied from the parent device 1 is stopped, the control unit 34 proceeds to step SC8. In step SC8, the control unit 34 stops the supply of the control signal SC2 that has been supplied to the LED drive circuit 43 until then, and ends the series of processes. As a result, the LED drive circuit 43 stops supplying the drive voltage DV to the LED 44 because the control signal SC2 is not supplied from the controller 34. Accordingly, the LED 44 is turned off.

If the determination result in step SC5 is “NO”, that is, referring to the registration table shown in FIG. 4, the incoming number display method of the telephone number data DN1, DN2 or mail address data MA is not the lighting of the LED 44. Then, the control unit 34 proceeds to step SC9.
In step SC9, the control unit 34 refers to the registration table shown in FIG. 4 to determine the OSD based on the name, nickname, etc. of the telephone holder registered for the telephone number data DN1, DN2 or the mail address data MA. The display signal SO or the telop display signal ST is generated and supplied to the character generator 41, and then the process proceeds to step SC10.
Thereby, the character generator 41 superimposes the OSD display signal SO or the telop display signal ST supplied from the control unit 34 on the video signal VP supplied from the video processing circuit 33, and supplies it to the display 42 as the video signal VO. To do. For example, as shown in FIG. 9, when an incoming call is received from the portable terminal 3 a owned by the father, a blue background is displayed in the upper left display area of the display 42 and “Daddy is receiving mail”. An OSD display 8 composed of words is made. For example, as shown in FIG. 10, when there is an incoming call of the mobile terminal 3 b owned by the eldest daughter “Mako”, “Mako's phone is ringing in the display area at the top of the display 42. Is displayed from right to left in the drawing.

In step SC10, the control unit 34 refers to the registration table shown in FIG. 4 and determines whether or not the display method for receiving the telephone number data DN1, DN2 or mail address data MA is OSD display. If the determination result in step SC10 is “NO”, the controller 34 does nothing and proceeds to step SC13. On the other hand, if the determination result in step SC10 is “YES”, that is, if the display method of the incoming call number data DN1, DN2 or mail address data MA is OSD display, the control unit 34 goes to step SC11. move on.
In step SC11, the control unit 34 determines whether or not the cursor button has been pressed. This determination is made when the operator presses the cursor button on the remote controller 45 when the operator presses one of the upper cursor button, the lower cursor button, the left cursor button, or the right cursor button on the remote controller 45. This is performed by detecting whether or not an infrared pulse control signal LR indicating is received by the remote control receiver 35 and then converted into an electric signal control signal RC.

  If the determination result in step SC11 is “NO”, the control unit 34 repeats the determination. When the control signal RC indicating that any one of the up cursor button, the down cursor button, the left cursor button, or the right cursor button is pressed is supplied to the control unit 34, the determination in step SC11 becomes “YES”. The control unit 34 proceeds to step SC12. In step SC12, the control unit 34 changes the OSD display signal SO in order to change the display position of the OSD display 8 on the display 42 according to the control signal RC supplied from the remote control receiving unit 35 in the process of step SC11. Thereafter, the process proceeds to Step SC13. For example, as shown in FIG. 9, when the display position of the OSD display 8 is the upper left of the display 42, if the operator presses the right cursor button of the remote controller 45, the control unit 34 displays the OSD display 8. In order to move the position to the upper right, the OSD display signal SO is changed. Therefore, as shown in FIG. 11, the display position of the OSD display 8 is moved and displayed on a part of the display 42.

In step SC13, the control unit 34 determines whether or not the supply of the modulation signal VE has been stopped. If the determination result in step SC13 is “NO”, the controller 34 returns to step SC9 and continues to supply the OSD display signal SO or the telop display signal ST. Accordingly, as long as the reception level signal RE is supplied from the receiver 39 to the control unit 34, the OSD display 8 or the telop display 9 is continuously displayed on the display 42.
On the other hand, if the determination result in step SC13 is “YES”, that is, if the supply of the modulation signal VE that has been supplied from the parent device 1 is stopped, the control unit 34 proceeds to step SC14. In step SC14, the control unit 34 ends the series of processes after stopping the supply of the OSD display signal SO or the telop display signal ST that has been supplied to the character generator 41 so far. As a result, the character generator 41 is not supplied with the OSD display signal SO or the telop display signal ST from the control unit 34, so that the video signal VP is supplied without being superimposed on the video signal VP supplied from the video processing circuit 33. VO is supplied to the display 42. Therefore, only the video of the television program is displayed on the display 42.

As described above, according to the first embodiment of the present invention, when a fixed telephone or a mobile terminal receives an incoming call while watching a TV program using the video display device 2 such as a television receiver, This is notified by turning on the LED 44 provided at the lower right of the front surface of the video display device 2 and the OSD display 8 or the telop display 9 on the display 42. Therefore, even if the volume for notifying the incoming call of the telephone is set low or forgetting to cancel the manner mode of the portable terminal, the person watching the TV program easily confirms the incoming call of the telephone. be able to. In addition, since it is not necessary to set the volume for notifying incoming calls to a level higher than necessary, there is no inconvenience to neighboring rooms, neighbors, and the like.
Further, according to the above-described first embodiment, only the name and nickname of the recipient are displayed on the display 42, and the telephone number and name of the caller are not displayed. Therefore, there is no risk of infringing on the sender's privacy. Further, according to the first embodiment described above, the incoming call is only the lighting of the LED 44 or the display on the display 42, and is not notified by voice. Therefore, viewing of TV programs is not hindered.

Furthermore, according to the above-described first embodiment, as can be seen from FIG. 9, when OSD is displayed for an incoming call, this display is displayed in an approximately quarter area of the television screen. However, when the OSD is displayed on the display 42, the OSD display can be moved to a desired display position by the operator operating the cursor button of the remote controller 45. Therefore, for example, even when the OSD display is made so as to cover the goal while watching a television program on which a soccer game is being relayed, the OSD display can be immediately moved to a portion other than the goal. As a result, there is no risk of missing an important scene that determines the goal.
Further, according to the first embodiment described above, the telephone number / mail address detecting circuit 13 detects the telephone number of the fixed telephone from the call transfer signal and the mobile phone number or mail address of the called party from the incoming call confirmation signal RC. is doing. The telephone number / mail address detecting circuit 13 supplies the telephone numbers of the fixed telephone and the portable terminal to the control unit 34 as telephone number data DN1 and DN2 and the mail address as mail address data MA. As a result, the control unit 34 refers to the registration table by the telephone number data DN1, DN2 or the mail address data MA, distinguishes between “voice incoming” and “electronic mail incoming”, and displays the OSD on the display 42. Ticker display or LED display. Therefore, the person who is watching the television program can identify whether it is “voice incoming” or “electronic mail incoming”. For this reason, in the case of “incoming e-mail”, a person who is watching a television program is not likely to miss an important scene.

In FIG. 12, the processing executed by the control unit 34 and the programs and data stored in the storage unit 36 are different from those of the first embodiment as described below. That is, the control unit 34 executes a first incoming call display process and a registration table creation process described below. In the first incoming call display process, when it is informed that there is an incoming call from the fixed telephone or the mobile terminal 3 whose telephone number is registered in the registration table, the first incoming call display process is registered for the telephone number. This is a process for generating an OSD display signal SO or the like according to the type of display and supplying it to the character generator 41 or the like. The registration table creation process is a process for creating the registration table described in the first embodiment while communicating with the monitor unit 52.

  The encoder 61 encodes the video signal VO output from the character generator 41 and supplies the encoded video signal VO to the transmitter 62 as an encoded signal EC2. When the LED drive signal LD corresponding to the control signal SC2 to be supplied from the control unit 34 to the LED drive circuit 43 is supplied, the encoder 61 encodes the LED drive signal LD together with the video signal VO. The encoded signal EC2 is supplied to the transmitter 62. The transmitter 62 performs modulation using the encoded signal EC2 supplied from the encoder 61 and transmits the modulated signal VE2 from the antenna 63.

The monitor unit 52 according to the second embodiment of the present invention includes an antenna 71, a receiver 72, a decoder 73, a display 42, a control unit 74, a storage unit 75, an LED drive circuit 43, and an LED 44. Have. The receiver 72 demodulates the encoded signal EC2 from the modulated signal VE2 received by the antenna 71 and supplies it to the decoder 73. The decoder 73 decodes the encoded signal EC2 supplied from the receiver 72 and supplies the obtained video signal VO to the display 42. The decoder 73 decodes the encoded signal EC2 supplied from the receiver 72 and supplies the obtained LED drive signal LD to the control unit 74.
The control unit 74 includes a CPU, a DSP, a sequencer, and the like, and executes each of the second incoming call display process and other processes based on the second incoming call display program and other programs stored in the storage unit 75. Is controlled by supplying a control signal SC2 or the like. The second incoming call display process is a process for generating the control signal SC <b> 2 based on the LED drive signal LD supplied from the decoder 73 and supplying it to the LED drive circuit 43.

  The storage unit 75 includes a RAM, a ROM, or a semiconductor memory such as a flash memory. The storage unit 75 includes a program storage unit, a working storage unit, and a data storage unit. The program storage unit stores in advance a second incoming call display program to be executed by the control unit 74 and other various programs. The working storage unit is used for work when the control unit 74 executes the above-described second incoming call display program and other various programs. The data storage unit stores in advance initial values and final values to be set in the decoder 73 and other components, and stores various data.

  Next, the operation of the video display system having the above configuration will be described. First, regarding the registration table storage processing of the control unit 34 of the tuner unit 51, the above-described implementation is performed except that communication is performed between the tuner unit 51 and the monitor unit 52 in order to display a registration table creation screen on the display 42. Since this is the same as in the case of the first embodiment (see FIG. 5), the description thereof is omitted. Of the operations of base unit 1, the operations related to the incoming call display, which is a feature of the present invention, are the same as those in the first embodiment (see FIG. 7), and the description thereof is omitted.

Next, of the operations of the tuner unit 51 having the above-described configuration, operations related to incoming call display, which is a feature of the present invention, will be described with reference to the flowchart shown in FIG. In FIG. 14, the processing of steps SC1 to SC4 is the same as the processing of steps SC1 to SC4 in the flowchart shown in FIG.
In FIG. 14, if the determination result in step SC5 is “YES”, that is, if the incoming call display method is to turn on the LED 44, the control unit 34 proceeds to step SC21. In step SC21, the control unit 34 refers to the registration table shown in FIG. 4, and a control signal for continuously lighting or blinking the LED 44 with the color registered for the telephone number data DN1, DN2 or the mail address data MA. After the LED drive signal LD for generating SC2 is generated and supplied to the encoder 61, the process proceeds to step SC7. Accordingly, the encoder 61 encodes the video signal VO output from the character generator 41 and the LED drive signal LD supplied from the control unit 34, and supplies the encoded signal EC2 to the transmitter 62. Accordingly, the transmitter 62 performs modulation using the encoded signal EC <b> 2 supplied from the encoder 61 and transmits the modulated signal VE <b> 2 from the antenna 63.

  In step SC7, the control unit 34 determines whether or not the supply of the modulation signal VE that has been supplied from the parent device 1 has been stopped. This determination is made based on whether or not the reception level signal RE supplied from the receiver 39 is not supplied when the input voltage of the modulation signal VE is equal to or higher than a predetermined voltage. If the determination result in step SC7 is “NO”, the controller 34 returns to step SC21 and continues to supply the LED drive signal LD. Accordingly, as long as the reception level signal RE is supplied from the receiver 39 to the control unit 34, the encoder 61 encodes the video signal VO and the LED control signal LD into the encoded signal EC2, and the transmitter 62 encodes the encoded signal EC2. The modulation signal VE2 modulated using the signal EC2 is continuously transmitted from the antenna 63.

  On the other hand, if the determination result in step SC7 is “YES”, that is, if the supply of the modulation signal VE that has been supplied from the parent device 1 has been stopped, the control unit 34 proceeds to step SC22. In step SC <b> 22, the control unit 34 stops the supply of the LED control signal LD that has been supplied to the encoder 61 and then ends a series of processes. Accordingly, since the LED control signal LD is not supplied from the control unit 34, the encoder 61 encodes only the video signal VO output from the character generator 41 and supplies the encoded signal EC2 to the transmitter 62. Accordingly, the transmitter 62 performs modulation using the encoded signal EC2 obtained by encoding only the video signal VO supplied from the encoder 61, and transmits the modulated signal VE2 from the antenna 63.

On the other hand, if the determination result in step SC5 is “NO”, that is, referring to the registration table shown in FIG. 4, the incoming number display method of the telephone number data DN1, DN2 or mail address data MA is not the lighting of the LED 44. Then, the control unit 34 proceeds to step SC9.
In step SC9, the control unit 34 refers to the registration table shown in FIG. 4 to determine the OSD based on the name, nickname, etc. of the telephone holder registered for the telephone number data DN1, DN2 or the mail address data MA. The display signal SO or the telop display signal ST is generated and supplied to the character generator 41, and then the process proceeds to step SC10.

  As a result, the character generator 41 superimposes the OSD display signal SO or the telop display signal ST supplied from the control unit 34 on the video signal VP supplied from the video processing circuit 33 and supplies it to the encoder 61 as the video signal VO. To do. Therefore, the encoder 61 encodes the video signal VO output from the character generator 41 and supplies the encoded video signal VO to the transmitter 62 as an encoded signal EC2. Then, the transmitter 62 performs modulation using the encoded signal EC <b> 2 supplied from the encoder 61, and transmits the modulated signal VE <b> 2 from the antenna 63.

In step SC10, the control unit 34 refers to the registration table shown in FIG. 4 and determines whether or not the display method for receiving the telephone number data DN1, DN2 or mail address data MA is OSD display. If the determination result in step SC10 is “NO”, the controller 34 does nothing and proceeds to step SC13. On the other hand, if the determination result in step SC10 is “YES”, that is, if the display method of the incoming call number data DN1, DN2 or mail address data MA is OSD display, the control unit 34 goes to step SC11. move on.
In step SC11, the control unit 34 determines whether or not the cursor button has been pressed. This determination is made when the operator presses the cursor button on the remote controller 45 when the operator presses one of the upper cursor button, the lower cursor button, the left cursor button, or the right cursor button on the remote controller 45. This is performed by detecting whether or not an infrared pulse control signal LR indicating is received by the remote control receiver 35 and then converted into an electric signal control signal RC.

If the determination in step SC11 is “NO”, control unit 34 repeats the determination. When the control signal RC indicating that any one of the up cursor button, the down cursor button, the left cursor button, or the right cursor button is pressed is supplied to the control unit 34, the determination in step SC11 becomes “YES”. The control unit 34 proceeds to step SC12. In step SC12, the control unit 34 changes the OSD display signal SO in order to change the display position of the OSD display 8 on the display 42 in accordance with the control signal RC supplied from the remote control receiving unit 35 in the process of step SC11. After being supplied to the character generator 41, the process proceeds to step SC13.
As a result, the character generator 41 superimposes the changed OSD display signal SO on the video signal VP supplied from the video processing circuit 33 and supplies it to the encoder 61 as the video signal VO. Therefore, the encoder 61 encodes the video signal VO output from the character generator 41 and supplies the encoded video signal VO to the transmitter 62 as an encoded signal EC2. Then, the transmitter 62 performs modulation using the encoded signal EC <b> 2 supplied from the encoder 61, and transmits the modulated signal VE <b> 2 from the antenna 63.

  In step SC13, control unit 34 determines whether or not supply of modulation signal VE that has been supplied from base unit 1 has been stopped. If the determination result in step SC13 is “NO”, the controller 34 returns to step SC9 and continues to supply the OSD display signal SO or the telop display signal ST. Accordingly, as long as the reception level signal RE is supplied from the receiver 39 to the control unit 34, the encoder 61 encodes the video signal VO into the encoded signal EC2, and the transmitter 62 uses the encoded signal EC2. The modulated modulation signal VE2 is continuously transmitted from the antenna 63.

On the other hand, if the determination result in step SC13 is “YES”, that is, if the supply of the modulation signal VE that has been supplied from the parent device 1 has been stopped, the control unit 34 proceeds to step SC14. In step SC14, the control unit 34 ends the series of processes after stopping the supply of the OSD display signal SO or the telop display signal ST that has been supplied to the character generator 41 so far. As a result, the character generator 41 is not supplied with the OSD display signal SO or the telop display signal ST from the control unit 34, so that the video signal VP is supplied without being superimposed on the video signal VP supplied from the video processing circuit 33. The VO is supplied to the encoder 61.
As a result, the encoder 61 encodes the video signal VO output from the character generator 41 on which the OSD display signal SO or the telop display signal ST is not superimposed, and supplies the encoded video signal VO to the transmitter 62. Accordingly, the transmitter 62 performs modulation using the encoded signal EC2 obtained by encoding only the video signal VO supplied from the encoder 61, and transmits the modulated signal VE2 from the antenna 63.

Next, the processing of the monitor unit 52 will be described with reference to the flowchart shown in FIG. In the monitor unit 52, when the power is turned on, the receiver 72 determines whether or not the modulation signal VE2 is received (step SD1). When the modulation signal VE2 is received, the determination result in step SD1 is “YES”, and the receiver 72 demodulates the encoded signal EC2 from the modulation signal VE2 received by the antenna 71 and supplies it to the decoder 73 ( Step SD2).
The decoder 73 supplied with the encoded signal EC2 decodes the encoded signal EC2 (step SD3). Next, the decoder 73 determines whether or not the LED drive signal LD is obtained by decoding the encoded signal EC2 (step SD4). If the determination result in step SD4 is “YES”, the decoder 73 proceeds to step SD5, supplies the decoded video signal VO to the display 42, and supplies the decoded LED drive signal LD to the control unit 74. To supply. Thereby, only the video of the television program is displayed on the display 42.

The controller 74 to which the LED drive signal LD is supplied generates a control signal SC2 based on the LED drive signal LD and supplies it to the LED drive circuit 43 (step SD6). The LED drive circuit 43 applies a drive voltage DV to the LED 44 based on the control signal SC <b> 2 supplied from the control unit 74. Thereby, for example, as shown in FIG. 1, when there is an incoming call from the base unit 1, the LED 44 provided at the lower right portion of the video display device 2 is continuously lit in red.
Next, the control unit 74 determines whether or not the supply of the modulation signal VE2 is stopped (step SD7). This determination is made based on whether or not the reception level signal RE2 supplied from the receiver 72 is not supplied when the input voltage of the modulation signal VE2 is equal to or higher than a predetermined voltage. If the determination result in step SD7 is “NO”, the controller 74 returns to step SD6 and continues to supply the control signal SC2. Thus, as long as the reception level signal RE2 is supplied from the receiver 72 to the control unit 74, the LED 44 is continuously lit or blinking in a predetermined color.

On the other hand, if the determination result in step SD7 is “YES”, that is, if the supply of the modulation signal VE2 that has been supplied from the tuner unit 51 is stopped, the control unit 74 proceeds to step SD8. In step SD8, the control unit 74 stops the supply of the control signal SC2 that has been supplied to the LED drive circuit 43 until then, and ends the series of processes. As a result, the LED drive circuit 43 stops supplying the drive voltage DV to the LED 44 because the control signal SC2 is no longer supplied from the controller 74. Accordingly, the LED 44 is turned off.
On the other hand, if the determination result in step SD4 is “NO”, that is, if the LED drive signal LD cannot be obtained by decoding the encoded signal EC2, the decoder 73 proceeds to step SD9 and performs decoding. The processed video signal VO is supplied to the display 42. Thus, the incoming call is displayed on the display 42 in the OSD display format or the telop display format on the video of the television program (step SD10).

  Next, the control unit 74 determines whether or not the supply of the modulation signal VE2 is stopped (step SD11). This determination method is the same as in the case of the process of step SD7. If the determination result in step SD11 is “NO”, the control unit 74 returns to step SD10. Thus, as long as the reception level signal RE2 is supplied from the receiver 72 to the control unit 74, the OSD display or the telop display is continuously displayed on the display 42. Among these, when the operator presses one of the cursor buttons on the remote controller 45 while the OSD is displayed on the display 42, as described above, the control unit 34 of the tuner unit 51 displays the OSD display. In order to change the position, the OSD display signal SO is changed and supplied to the character generator 41.

  As a result, the character generator 41 superimposes the changed OSD display signal SO on the video signal VP supplied from the video processing circuit 33 and supplies it to the encoder 61 as the video signal VO. Therefore, the encoder 61 encodes the video signal VO output from the character generator 41 and supplies the encoded video signal VO to the transmitter 62 as an encoded signal EC2. Then, the transmitter 62 performs modulation using the encoded signal EC <b> 2 supplied from the encoder 61, and transmits the modulated signal VE <b> 2 from the antenna 63. Therefore, since the video signal VO on which the OSD display signal SO changed to change the display position of the OSD display 8 is superimposed is decoded by the decoder 73, the display position of the OSD display 8 is displayed on the display 42. Changed and displayed.

On the other hand, if the determination result in step SD11 is “YES”, that is, if the supply of the modulation signal VE2 that has been supplied from the tuner unit 51 is stopped, the decoder 73 proceeds to step SD12 and performs decoding. The processed video signal VO is supplied to the display 42. Thereby, only the video of the television program is displayed on the display 42 (step SD12).
