Multifunction remote controller

1 is a function data transmission format of a general remote controller.

2 is a multifunctional remote controller according to the present invention.

3 is a remote controller function data transmission state diagram of FIG.

Article 4 is the transmission format according to FIG.

The present invention relates to a remote controller, and more particularly to a multi-function remote controller that selectively controls two sets of functions by one touch key input to control operation.

A remote controller (remote controller) (hereinafter referred to as a remote controller) controls the operation of a device far from a remote site and is currently used in all industrial and home appliances. For the same reason as above, several remote controllers exist in a home, which causes a problem of mutual interference. For example, there is a remote control of a television (TV) and a remote control of a video cassette tape recorder (VCR). In addition, it is inconvenient to operate two remote controllers for operating the TV and the VCR when the TV and the VCR are connected to watch the playback screen of the VCR.

Axial codes of the remote controller for controlling such TVs, VCRs, etc. for each product are as shown in FIG. 1 as follows: Leader Code (LC), CustumCoed (Key Code) (C, / D) The / signifies the bar (BAR), which means the inverted signal of the custom code C.) Date Code (D, / D). It consists of a continuous code. The reader code LC is a code indicating a transmission state from a remote control transmitter to a receiver, and the custom code (C, / C) is a product identification code such as a TV or a VCR, and the data code (D, / D) is a function ( Function selection data for selecting Function). Each of these codes is set to a predetermined number of bits, and the remote control receiver receives the corresponding custom code and data code to control the device with the corresponding function.

An example of watching an image reproduced from a VCR with a TV remote control and a VCR remote control having an output code form as shown in FIG. 1 will be described below. In order to watch a playback video screen of a VCR on a TV, first, a TV remote control is used to tune a TV channel into 3 or 4 channels to prepare for watching a VCR. As described above, by selecting a TV channel with the TV remote tone, by selecting the VCR function with the VCR remote control to operate in the VCR play mode (Play Mode), it is possible to watch the video screen reproduced from the VCR on the TV.

However, the method of using the remote control to control each set as described above was very inconvenient for the user because the two remote control to operate to watch the video screen of the VCR on the TV.

In order to solve this problem, there was a TV / VCR combined remote control for controlling the TV and the VCR with a single remote control, but this did not completely solve the inconvenience by operating by switching the operation mode of the remote control TV or VCR mode. In other words, when the TV / VCR remote controller is set to TV, only the TV is operated. When the VCR mode is selected, only the VCR is operated. , VCR function selection key, etc. was inconvenient to select.

Accordingly, an object of the present invention is to provide a multi-function remote control capable of simultaneously controlling a TV and a VCR by transmitting a function control code of a channel and a VCR of a TV by one touch.

Another object of the present invention is to provide a data format for controlling a TV and a VCR by input of a one touch key.

Another object of the present invention is to provide a circuit for transmitting remote control data of two different products by one touch key input.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a multi-function remote control circuit diagram according to the present invention, a plurality of keys connected in a mattress form between row lines for inputting kisscan data and column lines for outputting key data. A key matrix 12, an output port 01 to 03 for outputting scan data to the row lines at predetermined intervals, an input code 11 to 13 for inputting key data from the column lines, and a TV; It has an expansion port (EP) for inputting a simulated signal, and outputs the corresponding function data code when key data is input to one of the ports (11 to 13), and the TV channel data code and the VCR to the expansion port (EP). A transmission controller 14 for sequentially outputting function data, a TV simulated switch TSS connected between the expansion port EP of the transmission controller 14 and one of the row lines, and the transmission controller (14) output code It consists of a transmission interface for the wireless transmission. At this time, the transmission interface comprises a light emitting diode 16, a transistor 18, and a resistor 20 connected in series between a power supply voltage and a ground.

FIG. 3 shows the form of a code transmitted when a key is pressed while the TV simulated switch TSS of FIG. 2 is in the ozone position, and shows TV channel selection data and a VCR function button data code.

4 is a form in which the function selection key is continuously turned on while the TV simulated switch TSS is turned on as the transmission data format.

Hereinafter, the remote controller described above with reference to FIG. 2 will be described under the assumption that the remote control is a VCR remote control. First, the operation of the TV Simulate Switch (TSS) in the open state will be described.

When the TV simulation switch TSS is opened and a key for selecting a specific function of the VCR is pressed among the keys K1 to K9 located in the matrix 12, the transmission controller 14 performs the above-described first operation. Only the code as described above is transmitted to control the function of the VCR. The transistor 18 for inputting the code output from the transmission controller 14 to the base is switched in accordance with the code and driven by the light emitting diode 16 connected to the collector to transmit infrared rays to the remote control receiver of the VCR.

If the user selects the function key of the VCR, for example, the play key K2 while the TV simulation switch (TSS) is turned on, the scan pulse output of the output port (01) is the input port of the transmission controller (14). 12 is simultaneously input to the expansion port EP through the switch TSS. At this time, the transmission controller 14, which inputs the scan pulses to the expansion port EP and the input port 12, has a reader code (LC) and a custom code (C, / C) for tuning the channel of the TV as shown in FIG. And outputting data codes (D, / D) first, and then sequentially outputting reader codes (LC), kiss-term codes (C, / C), and data codes (D, / D) for selecting the function of the VCR. .

That is, when the VCR playback mode key is selected while the TV simulation switch (TSS) is turned on, the TV tuning data code for tuning the TV channel and the VCR function button data code for controlling the playback mode for the VCR operation are successively selected. Will output Therefore, if the required key (function key for operation) of the VCR is selected while the TV simulate switch (TSS) is turned on, the channel (for example, channel 3 or channel 4) of the TV is automatically tuned by the above operation and the VCR Is operated to operate two sets (TV / VCR) by one touch operation.

If the selected key is continuously pressed while the TV tuning data code and the VCR function button data code are output as shown in FIG. 3, the TV tuning data code (TV-S) and the VCR function button data code are output as shown in FIG. After that, the VCR function button data codes for operating the VCR in the play mode are sequentially and repeatedly sent out.

As described above, the present invention can control the two sets by one operation by connecting the TV simulation switch to the expansion port of the transmission controller and sequentially outputting TV channel selection data and VCR function selection data as one-touch.
