BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote controller for a television receiver, and more particularly to a review system for television programs.

[0002]

2. Description of the Related Art In order to confirm the contents of a program other than the program currently being watched by a television viewer, a push button switch which is usually provided on the tuner or remote controller of the television receiver body is provided corresponding to the channel. Since it is necessary to switch the channel for each station, the switching operation for the number of channels is required when it is desired to check a plurality of channels, and the operation is complicated or troublesome.

Therefore, in order to solve this problem, in the past, the television screen was divided into 9 screens or 16 screens, and a television screen having a multi-screen display function capable of simultaneously displaying the programs of a plurality of stations as moving images or still images. Machines have emerged and are in the news.

[0004]

However, in the simultaneous display system using the multi-screen, not only in the case of a moving image but also in a still image, a memory or other special circuit is added to perform signal processing in order to realize its function. Therefore, there is a problem in that it is unavoidable to increase the cost, and it is a system that is difficult to be adopted in a general household receiver.

The present invention has been made in view of such a problem, and its purpose is to pay attention to the fact that a remote control is attached to a television receiver, and a television having a function of easily reviewing a program of a channel. It is to provide a remote controller for a receiver.

[0006]

In order to achieve the above object, the remote controller of the television receiver of the present invention has the following structure. That is, the remote controller of the television receiver of the first invention includes a first key for inputting a channel update command;
In response to key operation, programs for all channels are switched and displayed at predetermined time intervals, and after one cycle, the program at the time of first key operation is displayed;

The remote controller of the television receiver of the second invention is
Second and third keys for inputting a channel update command and a channel release command; in response to the operation of the second key, the channel program is switched and displayed at predetermined time intervals, and in response to the operation of the third key And means for stopping the switching display and displaying the program when the second key is operated.

The remote controller of the television receiver of the third invention is
4th and 5th keys for inputting a channel update command and its cancellation command; in response to the operation of the 4th key, the program of the channel is switched and displayed at predetermined time intervals, and in response to the operation of the 5th key. Means for displaying the program at the time of the operation of the fifth key by stopping the switching display by means of; and.

The remote controller of the television receiver according to the fourth aspect of the present invention includes the sixth and seventh keys for inputting a channel update command and a channel release command; and a channel program in response to the operation of the sixth key. Switching and displaying at a predetermined time interval, when there is no operation of the 7th key before one cycle, the program at the time of operating the 6th key after one cycle is displayed, and when the operation of the 7th key has been input before one cycle Means for stopping the switching display and displaying the program at the time of the operation of the 7th key;

[0010]

Next, the operation of the remote controller of the television receiver of the present invention constructed as described above will be described. In the first invention, the programs of all channels are automatically switched and displayed by the first key operation, and the program of the original channel is displayed when the programs of the channels make one cycle. This is effective when you simply want to check (review) programs from other stations. The first key may be a newly installed one, but one existing push button switch can be used.

In the second invention, the program of the channel is automatically switched and displayed by the second key operation, and the program of the original channel is displayed when the third key operation is performed. This is effective when simply wanting to confirm the program of another station as in the first aspect of the invention.

In the third invention, the program of the channel is automatically switched and displayed by the fourth key operation, and the program of the channel at that time is displayed when the fifth key operation is performed. This is effective when searching for a program of a station you want to watch.

Further, in the fourth invention, the program of the channel is automatically switched and displayed by the operation of the sixth key, and if the operation of the seventh key is not performed by the time of one cycle, the program of the original station is displayed after one cycle. , If the 7th key is operated before one cycle, the program of the channel at that time is displayed. It is a combination of the first invention, the second invention and the third invention.

In the switching display in the second invention and the third invention, there are cases where all channels are targeted and some channels are targeted. Further, the two keys in the second invention to the fourth invention may use separate and independent push button switches (existing or new), but can also be used as one push button switch (existing or new). .

As described above, in the present invention, the program of each channel can be reviewed by simply adding a simple function to the remote controller without making any changes to the television receiver main body. The receiver can be easily applied to general household receivers without making the receiver expensive.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a remote controller of a television receiver according to an embodiment of the present invention. In FIG. 1, 1 is a keyboard in which push button switches are arranged, 2 is a CPU (central processing unit) for controlling the operation, 3 is an amplifier, and 4 is a photodiode for emitting infrared light, for example. The light emission of the photodiode 4 turns on / off the power of a television receiver (not shown) and designates a channel.

FIG. 1 shows the structure of a normal remote controller in terms of constituent elements, but in this embodiment, one existing push button switch on the keyboard 1 is provided with the first key, the second key and the third key.
It is used as any one of the 4th and 5th keys and the 6th and 7th keys.

Since the remote controller is always equipped with a push button switch for manually incrementing and decrementing the channel number, it seems appropriate to use one of the switches as the push button switch of the present invention. Be done.

When this one push button switch is operated, an operation signal is input to the CPU2, and one of the following four types of channel update programs is set in the memory of the CPU2.

That is, the first update program is a program that "displays the programs of all channels by switching them at predetermined time intervals in response to the update command, and displays the program at the time of inputting the update command, that is, the original program after one cycle". is there.

The second update program "displays the program of the channel by switching at a predetermined time interval according to the update command,
This program stops the switching display by the release command and displays the program when the update command is input. "

The third update program "displays a channel program switched at predetermined time intervals according to an update command,
The program stops the switching display by the release command and displays the program when the release command is input. "

Further, the fourth update program displays "the program of the channel is switched and displayed at predetermined time intervals according to the update command, and if there is no release command by the end of one cycle, the program at the time of input of the update command is displayed after one cycle. If there is a cancellation command by the end of one cycle, switching display is stopped at that point and the program at the time of cancellation command input is displayed. "

In short, the remote controller of the present invention can be divided into four types, and hereinafter, "one push button switch" to be used will be referred to as "review button" and each type will be described.

The first type is a remote controller of the type in which the review button (first key) is operated once when the user wants to review the program on each channel. This key operation is performed by the CPU
Input to 2 as a channel update command. CPU2 is
The first update program set in the memory is executed.

As a result, in the main body of the television receiver, the programs of all the channels are sequentially switched and displayed at predetermined time intervals on the television screen, and the program is stopped when the program of the original channel is restored.

The second type is to push the review button (second and third keys) 2 when the program of each channel is desired to be reviewed.
It is a type of remote control that can be operated once. This key operation is input to the CPU 2 as a channel update command for the first operation and as an update cancellation command for the second operation. The CPU 2 executes the second update program set in the memory.

As a result, in the main body of the television receiver, the program of the channel is sequentially switched and displayed at a predetermined time interval on the television screen by the first key operation. This is repeated until there is a second key operation. When the second key operation is performed, the television screen returns to the program of the original channel. Therefore, in this case, programs of all channels may be switched and displayed, and programs of some channels may be switched and displayed.

The third type uses the review button (4th and 5th keys) when the user wants to review the program on each channel.
It is a type of remote control that can be operated once. This key operation is input to the CPU 2 as a channel update command for the first operation and as an update cancellation command for the second operation. The CPU 2 executes the third update program set in the memory.

As a result, in the main body of the television receiver, the program of the channel is sequentially switched and displayed at a predetermined time interval on the television screen by the first key operation. This is repeated until there is a second key operation. When the second key operation is performed, the television screen is stopped at the program of the channel at the time of the second key operation. Therefore, also in this case, as in the case of the second type, there are cases where programs of all channels are switched and displayed, and cases where programs of some channels are switched and displayed.

The fourth type is to push the review button (6th and 7th keys) to 2 when reviewing the program of each channel.
It is a type of remote control that can be operated once. This key operation is input to the CPU 2 as a channel update command for the first operation and as an update cancellation command for the second operation. The CPU 2 executes the fourth update program set in the memory.

As a result, in the main body of the television receiver, the program of the channel is sequentially switched and displayed at a predetermined time interval on the television screen by the first key operation. If the second key operation is not performed before all the channels have been cycled, the television screen will be stationary when the original channel program is switched to. On the other hand, if the second key operation is performed before all the channels are cycled, the television screen is stopped at the channel program at the time of the second key operation.

The switching of each channel of the television screen may be realized by causing the CPU 2 to execute the update program as described above. For example, as shown in FIG. 2, the channel switching circuit 5 is arranged in parallel with the switch of the review button. It may be realized by providing it in the. Although the channel switching circuit 5 is not shown,
For example, in the case of the remote controller of the first type, it is a circuit for intermittently turning on the switch for a few minutes by a single operation of the review button, that is, a circuit for automatically performing increment or decrement. it can.
In addition, in the second to fourth types, only some functions are added to it.

Here, the time interval for switching the programs of the channels one after another during the review seems to be several seconds at most for the purpose of the review, but such a time interval is fixedly set in advance.

During the review, the voice may or may not be output, but it is better to turn off the voice automatically when the time interval for switching is short. This is to eliminate the noisy element in which the sound changes rapidly.

Further, it is better to display the channel number during the review. In the case of the first type and the second type, the necessity is small, but in the case of the third type and the fourth type, it is possible to confirm at a glance which program is being performed on which channel, and it matches the purpose of the review. To do.

[0037]

As described above, in the remote controller of the television receiver of the present invention, the simple operation of each channel is achieved by adding a simple function to the remote controller without changing the main body of the television receiver. Because I am able to review the program,
There is an effect that the television receiver is not expensive and can be easily applied to a general household receiver.
