Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control transmitter for remotely controlling a television receiver and its peripheral equipment.

[0002]

2. Description of the Related Art In recent years, with the widespread use of video devices such as VTRs and video discs, which are television receivers and their peripheral devices, the chances of using these devices in combination at home have increased. These devices are generally equipped with a Mokon transmitter, which helps to simplify the operation. However, each of these remote controllers must use a separate remote controller transmitter, and if these remote controllers increase, they will run out of storage space, will be searched unnecessarily when needed, and it will be difficult to know which remote controller is for which device. It disappears and various troubles are appearing. The reason for using individual remote controllers is that one remote controller prevents multiple devices from operating at the same time, and the remote controller code is intentionally changed. However, this causes the above-mentioned inconvenience. To solve this problem, some remote control transmitters are equipped with operation buttons for a plurality of devices. For example, there are things that can move a TV and video, and things that can move a video disc and the like. But,
These remote controllers have other inconveniences as the number of buttons that can be operated increases and the number of buttons increases, making the remote controller transmitter larger, and because there are too many buttons to decide which one to press.

On the other hand, in order to increase the functions that can be operated without increasing the number of buttons, there is a method of switching the code output when these buttons are operated by another switch. However, this method requires the user to perform a large number of operations each time the switch is operated by the user, and also requires the user to consider how to operate the switch. An example of this can be found in JP-A-4-160897. FIG. 5 shows a front view of the operation unit of the remote control transmitter. This remote control transmitter can switch and control both the CD player and the VTR.

In FIG. 5, S1 to S12 are CD and V.
This button is used to control TR, and S13 is CD and VTR.
And S14 is a switch for switching the operation mode of the remote controller between normal and storage.
Japanese Unexamined Patent Publication No. 4-160897 is characterized in that it is devised for easy storage in addition to switching and using devices, but this function is not related to the description of the present invention. Detailed description is omitted. As described above, there is a remote controller that can be switched and operated, and a plurality of devices can be operated by a single remote controller, but an operation for switching is required, which is not easy to use. Further, JP-A-2-86392 is proposed as an idea for improving usability.

As shown in FIG. 6, the configuration in this case comprises a CPU, an operation content detection unit, a signal output unit, a reception buffer, a ring buffer, a temporary registration buffer and a registration sequence holding memory. If so, the CPU automatically stores the procedure in the memory for holding the registered sequence, and once it is stored, the series of codes stored previously can be sent by simply operating one button that has been decided. Is to do. For example, when you want to watch a VTR, you usually send a power command of the TV, send a command to change the screen of the TV to VIDEO, and set the VTR to PL.
It is convenient in that the number of operations is small because only one button needs to be operated when it is necessary to send a command for AY, but the number of buttons on the remote control transmitter does not decrease.

[0006]

In order to improve the operability of an AV system in which a plurality of devices are combined, one remote control transmitter can operate all the devices, and the number of buttons on the remote control transmitter is the minimum required. It must be limited, easy to operate, and transparent to the user.

[0007]

In order to solve the above problems, the structure of the present invention is such that one remote control transmitter includes a remote control button group (group A) for input switching of a television receiver.
Other button groups (group B) for operating various other functions, keyboard storage means for storing the last operated button of group A, and a page designated by the keyboard storage means and its page Is the address that corresponds to each operation button one-to-one, and the remote control code of the device that should be connected to the input terminal of the television receiver that can be switched by the last operated group A button that is most suitable for the display of each button. It is provided with stored transmission code storage means and control means for controlling them. The control means is A
When a button in the group is operated, a remote control code for switching and designating a predetermined input terminal of the television receiver is transmitted to each button, and the input terminal number of this button is stored in the keyboard storage means. When the group B button is operated, the page is designated by the contents of the keyboard storage means, which is stored in the corresponding address of the group B button of the transmission code storage means, that is, of the device displaying the image on the screen of the television receiver. It works so that the optimum remote control code is transmitted to the B group button. The above is the configuration of claim 1.

According to a second aspect of the present invention, the transmission code storage means is rewritable, and the transmission code stored therein can be arbitrarily rewritten by the user. As a control means for rewriting the transmission code. In addition to the function of claim 1,
A function for writing arbitrary data to an arbitrary address of an arbitrary page of the transmission code storage means is added according to a predetermined specific procedure input from the keyboard means.

According to a third aspect of the invention, in addition to the configuration of the second aspect, a read-only storage means for storing transmission codes of various functions of various makers is provided, and the control means has the function of claim 2. In addition, for convenience when the user writes the transmission code in the rewritable transmission code storage means, the control means reads out the necessary data from the dedicated storage means by a special procedure determined in advance from the keyboard means. A function is added in which the read code is stored in a desired address of the transmission code storage means.

[0010]

According to the structure of claim 1, peripheral equipment connected to not only the television receiver but also a predetermined input terminal of the television receiver with one remote control transmitter and a limited number of buttons. Can be controlled. Moreover, the number of operations does not increase for that reason. According to the configuration of claim 2, the manufacturer does not specify the device to be connected to the input terminal of the television receiver, and the same operation as described above can be obtained even if the user connects any peripheral device. It is a thing. Further, according to the structure of claim 3, in order to obtain these effects, as a preparation, the user is connected to the transmission code storage means of the remote control transmitter of the device which he / she is connected to each input terminal of the television receiver. Although it is necessary to store the remote control code, there is an effect that the operation at that time is easy.

[0011]

EXAMPLES Examples of the present invention will be described below with reference to FIGS. 1 to 4 and Table 1.
Will be described with reference to Table 3. FIG. 1 is a front view of a remote control transmitter according to an embodiment of the present invention. In FIG. 1, a group A surrounded by a broken line is an input switching operation button of the television receiver, which transmits an input switching remote control transmission code for the television. Group B is operation buttons for devices other than the television receiver. In this example, the remote control transmission codes of the television receiver, VTR (video), LD (video disc), and CS tuner are output.

FIG. 2 shows a first embodiment of the present invention.

In FIG. 2, reference numeral 15 is infrared ray emitting means, 14 is transmission pulse generating means, 12 is keyboard input means, 11 is keyboard storage means, 16 is transmission code storage means, and 13 is control means for controlling these. Table 1 describes the code table, which is the storage content of the transmission code storage means 16, by the function.

[0013]

[Table 1]

Next, the operation of the remote control transmitter constructed as described above will be described. When the operation button of the keyboard input means 12 is pressed, the control means 13 determines whether the operation button belongs to the A group or the B group of FIG. When the button belongs to the group A, the information indicating which button has been operated is written in the keyboard storage means 11, and then the transmission code recorded in the address corresponding to the operated button from the transmission code storage means 16, in this case. To read out the TV input switching code,
An infrared remote control code is transmitted from the infrared light emitting means 15 via the transmission pulse generating means 14. As a result, the input of the television receiver is switched, and the video signal of the device connected to each input terminal is displayed. As can be seen from (Table 1), the code transmitted at this time is the "TV" code if the "TV" button is operated, and the "V1" code if the "V1" button is operated, regardless of the video input state of the television. coming out.

On the other hand, when the button belonging to the B group is operated, the A operated last from the keyboard storage means 11 is operated.
A column in which the button of the group is read out, and the address corresponding to the button operated from the transmission code storage means 16 and the current video input state of the television are read according to the information and the information indicating which button is pressed. The transmission code of 1 is read out, and the transmission pulse generating means 1 is operated in the same manner as the A group button.
An infrared remote control code is transmitted from the infrared light emitting means 15 via 4.

As can be seen from (Table 1), the code transmitted at this time changes depending on the image input state of the television, for example, the last operated group A button is "TV",
Now, if the "1" button is pressed, the television code "1" is transmitted, and if the last operated group A button is "V1", the VTR code "1" is transmitted. . Similarly, if the last operated group A button is "V2", the LD code "1" is transmitted, and if it is "V3", the CS tuner code "1" is transmitted.

FIG. 3 shows a second embodiment of the present invention.

[0018]

[Table 2]

(Table 2) describes the code table, which is the storage content of the transmission code storage means 21, by the function. In addition to the function of the control means 13 of FIG. 2, the control means 22 detects a special input procedure or a special operation method of the keyboard input means 12, and detects the “any function code of any manufacturer” in (Table 2). It plays the role of writing an arbitrary code there. As an example of the special input procedure, "specific procedure" can be considered, and as an example of the special operation method, "simultaneous pressing of two or more buttons" can be considered. Next, a procedure for storing an arbitrary code in a specific procedure will be shown. For example, if the buttons "1", "5" and "9" are successively input twice in this order, the code input state is set. The address of the rewritable transmission code storage means 21, that is, the line of (Table 2) is determined by the next button to be pressed. The column of (Table 2) is the keyboard storage means 11
Determined by The code to be stored is determined and stored by the next operation button (number). If you operate the number buttons with the required number of digits, one code will be stored. Next, select the button to be stored and repeat these steps. As a method of exiting the code input state and returning to the normal use state, there is a method of automatically exiting if there is no button operation for a certain period of time.

FIG. 4 shows claim 3 in one embodiment of the present invention.
3 is a block diagram of the remote control transmitter of FIG. In FIG. 4, reference numerals 11, 12, 14, 15, and 21 are the same as those in FIG. 3, 33 is a read-only storage means, and 32 is a control means for controlling them. The control means 32 can store an arbitrary code, but the operation becomes complicated because the control means 22 of FIG. 3 has a function of easily storing an arbitrary code from a menu prepared in advance, although not optional. It has a. The read-only storage means 33 stores the "prepared menu", that is, the "prepared code".
An example of the contents is shown in (Table 3).

[0021]

[Table 3]

Next, a method of storing in the rewritable transmission code storage means 21 will be described. The code input state in the specific procedure is the same as the operation of the control means 22. The address to be stored (column in Table 2) is determined by the keyboard storage means 11. The code groups to be stored are in (Table 3).
That is, the columns in (Table 3) may be designated. Here, press the button "1". The control means 32 reads out all the data in the column of "code group 1" of (Table 3) from the read-only storage means 33 and rewrites them, and the transmission code storage means 21 is possible.
It is stored in the address specified at the end of each. This operation may be repeated for each column in (Table 2).

[0023]

According to the present invention, a television receiver and its peripherals can be easily operated with a single remote controller having a small number of buttons. That is, if you press ">>" while watching the VTR, the VTR will be
">>" code (fast-forward code) is issued from the remote control transmitter, the VTR enters the fast-forward state as expected, and if you press ">>" while watching the LD, the LD ">>" code will be as you expected. (LD fast-forward code) is emitted from the remote control transmitter, and the LD enters the fast-forward state as expected. In this way, the remote control transmitter automatically determines and transmits the code that the user expects, which is very convenient.
These functions are available only in a predetermined device in claim 1, but in claim 2, this function can be extended to any device, and in claim 3, there is an effect that setting can be further facilitated.
