Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a television reception system that is used by combining a small-sized television receiver placed at hand and a large-sized television receiver placed far away.

Recently, television receivers that simultaneously display a different television image on a portion of one television image, and television receivers that simultaneously display two television images using two large and small cathode ray tubes, have become commercially available. has been done.

However, with such a television receiver, 2
Despite having two independent image receiving functions, the two images were projected within the same plane and could not be used separately as two receivers.

The present invention has been made in view of the above, and uses two separable large and small television receivers to enable selection between a small television receiver at hand and a large television receiver located far away. This provides a television reception system that allows remote control of stations, volume, etc.

The present invention will be described below with reference to embodiments shown in the drawings.

In the embodiment shown in FIG. 1, the television receiver system of the present invention is constructed by combining two large and small television receivers 1 and 2. A remote control signal receiving section 3 is provided on the small-sized television receiver 2, and a remote control signal transmitting section 4 is provided on the small-sized television receiver 2. It is possible to select a channel on the small-sized television receiver 2, and also to perform channel selection, volume adjustment, etc. on the large-sized television receiver 1 by remote control. Furthermore, here, a video exchange switch 6 is specially provided in the operation key section 5, and the video currently being received by each television receiver 1, 2 is instantly replaced by the switch 6.

The large television receiver 1 used here is no different from the configuration of a normal television receiver with a remote control function, but the small television receiver 2 has a configuration as shown in FIG. It has a unique structure. That is, in FIG. 2, 7 and 8 are the same channel selection section and image receiving circuit section as those used in a normal television receiver, and in particular, 5, 9, and 10 constitute the television image receiving system according to the present invention. These are a new operation key section, a signal processing section, and a remote control signal transmission section.

When an appropriate key operation is performed on the operation key section 5, this is processed in the signal processing section 9 and is sent to the channel selection section 7 based on the output signal A from the processing section 9.
is controlled, and at this time the small television receiver 2
Then, a predetermined channel is selected and received. When another appropriate key operation is performed, an output signal B is derived from the signal processing section 9 and supplied to the remote control signal transmitting section 10, from which a remote control signal is transmitted. Therefore, at this time, in the large television receiver 1, the signal is received by the remote control signal receiving section 3, whereby a predetermined channel is selected and received.

Note that here, remote control signal transmitter 1
The remote control signal transmitted from the transmitter 10 may be any one of light, ultrasonic waves, radio waves, etc., and the transmitter 10 and receiver 3 may be connected by wire and transmitted as an electrical signal.

Next, a more detailed block diagram of the signal processing section 9 is shown in FIG. 3, and the channel selection operation will be explained below. Here, the signal processing section 9 includes a data comparator 11, a timing signal generator 12,
ROM13, RAM14, data selector 15,
latch circuits 16, 17, and BCD output circuit 18,
Channel information corresponding to the reception channels of each receiver 1 and 2 is normally transmitted to the latch circuit 1.
It is held at 6,17.

If you now want to switch the reception channel of the small television receiver 1, turn on a predetermined channel selection key in the operation key section 5, and this input information will be transferred to the data comparator 1.
1, the program contents are compared with the program contents of the ROM 13 to determine various modes and operation signals, and then supplied to the data selector 15. At this time, predetermined channel information corresponding to the contents of the RAM 14 is sent from the data selector 15 to the latch circuit 16. is input. Therefore, at this time, an output signal A matching this channel information is derived from the BCD output circuit 18, and as a result, the small television receiver 2 is switched to the desired channel. Further, when switching the reception channel of the large television receiver 1, by turning on a predetermined channel selection key, predetermined channel information is inputted from the data selector 15 to the latch circuit 17 by a similar operation, and the output signal B is output from the BCD output circuit. is derived. As a result, the remote control signal section 10 transmits a remote control signal matching this channel information, and the reception channel of the television receiver 1 is switched to the desired channel.

Here, when the video exchange switch of the operation key section 5 is turned on again, the channel information held in the latch circuits 16 and 17 is exchanged with each other based on the command from the data selector 15, and at this time, each receiver 18, The channel being received by receiver 19 is switched, and as a result, the images of each receiver 18 and 19 are interchanged.

In the above embodiment, a case has been described in which the channel selection of the large-sized television receiver 1 is remotely controlled by key operations on the operation key section 5 of the small-sized television receiver 2. It is also possible to remotely control volume adjustment, power on/off operations, etc.

According to the television receiving system of the present invention,
As mentioned above, two large and small television receivers that are separable and have individual reception functions are used in combination, with the large television receiver equipped with a remote control receiving section and the small television receiver equipped with a remote control receiver. Since a control transmitter is provided, large television receivers can be placed far away.
By keeping a small television receiver close at hand and operating it remotely as necessary, it is possible to easily tune in, adjust the volume, etc. of a large television receiver located far away.

Furthermore, according to the image receiving system of the present invention, even if you are watching a program from a specific station on a large television receiver, you can easily check the contents of another station's program on a small television receiver. When the desired situation occurs during this confirmation,
By remote control operation on the small television receiver side, this scene can be switched to the screen of a large television receiver with almost no time delay, which is extremely convenient.
