The slave television 20B is the same as the slave television 20A, and a description thereof will be omitted.

Next, the operation of the television receiving system according to the present invention will be described. First, the basic control mode of the parent television 10 will be described with reference to the flowchart of the parent television control means 16 of the parent television 10 shown in FIG.
When the power button 13 of the remote control input device 11 is pressed, a power-on signal is input to the parent television control means 16 via the reception means 15 (ST1 in FIG. 3), and the power of the parent television 10 is turned on (ST2 in FIG. 3). Is displayed on the display 19. And the channel selection button 1 of the remote control input device 11
When 4 is pressed, a channel selection signal is input to the parent television control means 16 via the reception means 15 (ST3 in FIG. 3), and the parent television control means 16 transmits a channel switching signal to the channel reception means 17 (ST4 in FIG. 3). , The channel is switched, and the image displayed on the display 19 from the antenna line 5 via the channel receiving means 17 and the image synthesizing means 18 changes. When the power button 13 of the remote control input device 11 is pressed to turn off the parent television 10, a power-off signal is input to the parent television control means 16 via the reception means 15 (ST5 in FIG. 3), and the power of the parent television 10 is turned off. Is turned off (ST6 in FIG. 3), and the image on the display 19 disappears.

Next, the manner in which the parent television 10 controls the child televisions 20A and 20B will be described with reference to the flow chart of the parent television control means 16 of the parent television 10 shown in FIG. , Child TV 20A, 20
When B is also on, the images from the child televisions 20A and 20B are synthesized by the image synthesizing means 18 and are projected on the corners 19A and 19B of the display 19 of the parent television 10.
With the images of the corners 19A and 19B, the parent can monitor the broadcast contents of the child televisions 20A and 20B that the child is watching on the parent television 10, and if this adversely affects education or hinders study, Parents will be able to take care.

[0012] For example, when it is considered that the image of the child television 20A adversely affects the education of the child, the television selection button 12 on the child television 20A side of the remote control input device 11 is pressed, and the channel selection button 14 is depressed. The channel selection signal of the selected slave TV 20A is input to the master TV controller 16 via the receiver 15 (ST1, ST1 in FIG. 4).
2), the parent television control means 16 outputs a channel switching signal to the child television 20A (ST3 in FIG. 4). Then, upon receiving a channel switching signal as described later, the child television 2
The channel of 0A is switched. In this manner, the channels of the child televisions 20A and 20B can be changed on the parent television 10, so that the parent does not have to go to the children's room.

For example, since the child television 20A is turned on until late at night, when the child television 20A is forcibly turned off, the television selection button 12 of the remote control input device 11 is pressed, and the power button 13 is pressed. The power-off signal of 20A is input to the parent television control means 16 via the receiving means 15 (FIG. 4).
ST1, ST4), the parent television control means 16 outputs a power-off signal to the child television 20A (ST5 in FIG. 4). Then, upon receiving a power-off signal as described later, the power of the slave television 20A is turned off. As described above, since the power of the child televisions 20A and 20B can be turned off at the parent television 10, the parent does not have to go to the child's room.

In order to change the channel of the child television 20B, the user presses the television selection button 12 of the remote control input device 11 and presses the channel selection button 14, and the channel selection signal of the selected child television 20B is transmitted to the parent television control means. 16
(ST6, ST7 in FIG. 4), the parent television control means 16 outputs a channel switching signal to the child television 20B (ST8 in FIG. 4), and the channel of the child television 20B is switched. When the child TV 20B is forcibly turned off, the TV selection button 12 of the remote control input device 11 is pressed, and the power button 13 is pressed. Enter (Fig. 4
ST6, ST9), the parent television control means 16 outputs the child television 2
A power-off signal is output to 0B (ST10 in FIG. 4), and the power of the child television 20B is turned off.

Next, a description will be given of a control mode of the slave television set 20A with reference to the flowchart of FIG. 5. To turn on the slave television set 20A, when the power button 23 of the remote control input device 21 is pressed, a power ON signal is received. Child television control means 2 through means 25
6 (ST1 in FIG. 5), and if the television power-off is not being held (ST2 in FIG. 5) according to the mode of step ST12 in FIG. 5 described later, the power of the slave television 20A is turned on (ST3 in FIG. 5). An image is displayed on the display 29. When the channel selection button 24 of the remote control input device 21 is pressed, a channel selection signal is input to the child television control means 26 via the receiving means 25 (ST4 in FIG. 5), and this signal is not transmitted from the parent television 10 (ST5 in FIG. 5). The selected channel corresponds to step ST8 in FIG.
When the channel is not prohibited according to the mode (FIG. 5 S
T6), a channel switching signal is output from the child television control means 26 to the channel receiving means 27 (ST in FIG. 5).
7) The video input from the antenna line 5 is switched, and the video displayed on the child television 20A changes.

In step ST4 in FIG. 5, when the channel selection signal input to the child television control means 26 is from the parent television 10, that is, in consideration of an adverse educational effect as described in step ST3 in FIG. Has changed the channel (ST5 in FIG. 5),
Outputs a channel switching signal to the channel receiving means 27, and holds the channel which has been broadcast so far for a certain period of time, for example, one hour (S in FIG. 5).
T8). Thereby, when the channel is changed from the parent television 10, the channel prohibition is maintained for one hour, and the switching between the parent and child channels is prevented.

To turn off the sub-television 20A, when the power button 23 of the remote control input device 21 is pressed, a power-off signal is input to the sub-television control means 26 via the reception means 25 (FIG. 5).
ST9), the power of the child television 20A is turned off (FIG. 5).
ST10), the image on the display 29 disappears.

In step ST9 in FIG. 5, when the power-off signal input to the child television control means 26 is from the parent television 10, that is, in consideration of an adverse effect on education as described in step ST5 in FIG. When the power is turned off (ST11 in FIG. 5), the television power is kept off for a certain period of time, for example, one hour (ST12 in FIG. 5). In this way, when the power is turned off from the parent television 10, the power off is maintained for one hour, thereby preventing the parent and the child from turning on and off the power.

The remote control input device 11 of the parent television 10
Is provided with a channel selection prohibition button for the child televisions 20A and 20B, and when this button is pressed, the parent television control means 16 transmits a channel selection prohibition signal to the child television control means 26 to register the channel, and the prohibited channel is set. May not be selected. By doing so, it becomes possible to prohibit the channel selection of the child television sets 20A and 20B in advance by watching the television program.
