BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control and a remote control signal processing apparatus suitable for producing a television (TV) set and displaying a selected number of models on an OSD screen.

In general, a remote controller is used as a combined device having a TV / VCR selection button so as to drive a TV and a VCR set separately. Such a remote controller is configured to generate together a key mode representing a head code, a custom code and an actual mode of operation in its operation.

However, since the operation codes are composed of different data according to the manufacturer and the model of the product, a multi-function remote controller has been developed that partially enables the remote controller of one product, which cannot operate the product of another manufacturer or other models.

Such a TV / VCR combined multi-function remote controller is configured to generate key code data for a model of a TV product, even if the manufacturer and model of the TV set are different. To explain this in more detail, first select the TV / VCR selection button as the TV mode on the multi-function remote control, and then press a separate TV setting key or button to enter the mode in which the microcomputer in the remote control can generate a code signal for the desired TV set. Make it. After that, while looking at the user manual or guide recorded to identify the manufacturer of the TV set and the model of the product to be operated as a number, select and press the number (0 to 9) keys or buttons arranged on the remote controller. . Then, the microcomputer in the remote control functions corresponding to the manufacturer and the product model selected by the number as described above for about four to five functions such as power on / off, channel up / down, volume up / down, and voice mute. It is ready to carry out, and by pressing the TV setting key once again, the currently selected manufacturer and model number is set in the storage means inside the remote control. The remote controller thus set generates only a key code corresponding to the new product until there is a change to the new product.

Such a multi-function remote controller is not provided with an LCD (liquid crystal) display device that can display the manufacturer and model number. Therefore, in the general remote control without the LCD display function, there is no method of checking whether the manufacturer and model number currently set on the remote control are set for which manufacturer's TV set. Therefore, there was no choice but to confirm by directly operating the TV set using the multi-function remote control. However, if an LCD device that performs a display function on a remote controller is added to solve such a problem, there is a problem that not only the volume is increased but also the manufacturing cost increases.

Accordingly, the present invention provides a display device that displays a manufacturer and a product model number which are set on a TV / VCR combined remote controller without an LCD display function and are newly set on a OSD screen using a VCR.

According to the present invention for achieving this object, a multi-function remote control capable of driving the manufacturers of a plurality of different TV products and models of the TV product, and displays the corresponding OSD characters in accordance with the remote control data output from the remote control A TV manufacturer and a model display device comprising a signal processing device, the multi-function remote control comprising: a mode setting key for selectively generating an on or off setting mode for setting one selected TV product manufacturer and a product model; A number key for selecting the selected TV manufacturer and model as a number; A setting mode control unit for selectively outputting the setting mode signal generated from the mode setting key or the number data generated from the number key; A storage unit for storing the number data selectively provided from the setting mode control unit; The number data previously recorded in the storage unit is read in accordance with the set mode signal in the on state provided from the set mode control unit, and the number key is read in accordance with the set mode signal in the off state provided from the set mode control unit. A recording / reading control unit controlling to record the number data generated from the recording unit into the storage unit; An output section for outputting the number data read out from the storage section by the read / write control section; The remote control signal processing apparatus may include: an OSD control circuit which receives the number data output from an output unit of the remote controller and displays the number data on the OSD screen.

Hereinafter, the present invention will be described in detail as follows with reference to the accompanying drawings.

1 shows a block diagram of a multifunction remote controller 10 having a plurality of numeric buttons and function buttons.

The remote controller 10 includes a TV setting key signal input unit 1 for receiving a TV setting mode signal generated from the TV setting key 5 selected in the key matrix, and a number button for selecting a number of a manufacturer and a product model of the TV set. A number key signal input unit 2 for receiving a signal generated from (6), a setting mode control unit 3 for determining a signal input from the TV setting key signal input unit 1 or the number key signal input unit 20; A storage unit 7 for storing the manufacturer and model numbers, a recording and reading control unit 4 for recording and reading the manufacturer and model numbers in the storage unit 7, a number key input unit 2, and a recording / reading unit. And an output unit 8 for outputting data output from the control unit 4.

The TV setting key 5 is configured as a toggle switch which is repeated on and off in order to set the remote controller 10 to the manufacturer and model of the desired TV set. Therefore, when the TV setting key 5 is operated once, i.e., in the on state, the TV setting mode for the TV manufacturer and model setting is progressed, and when it is operated again, i.e., in the off state, the TV setting mode is It is repeated to exit.

The setting mode control section 3 selectively selects the output data of the number key input section 2 in accordance with the input of the TV setting key 5, as shown by the switch 3 'in the same drawing to illustrate its function. To control. That is, when the TV setting mode signal is input from the TV setting key input unit 1, the switch 3 'is turned on so that the number signal of the number key input unit 2 can be received. When the TV setting signal is input again from the above, the switch 3 'is turned off so that no further number signal is received. This function is to turn on or off the switch 3 'in accordance with the 0 or 1 state of the flag internally using the TV mode flag, as described with reference to FIG.

The storage unit 7 stores the number data applied via the setting mode control unit 3.

The recording / reading control section 4 according to the state of the TV mode flag of the setting mode control section 3, if the mode flag is 1, the storage section 7 uses the number signal provided from the number key input section 2 as new number data. If the mode flag is 0, the old number data already stored in the storage unit 7 is read.

The number data read out from the storage unit 7 by the recording / reading control unit 4 is output through the data output unit 8 together with the flag bits of the mode setting control unit 3.

2 is a block diagram of a remote control signal processing device 20 for displaying a signal generated by the remote control shown in FIG. 1 on an On Screen Display (OSD) screen according to the present invention.

The remote control signal processing apparatus 20 typically uses a timer microcomputer of a VCR used to receive a remote control signal and correspondingly provide a visual indication on an OSD screen. The timer micom 20 includes a key input determination unit 12, an OSD on / off control unit 13, and an OSD character data output unit 14.

The receiver 11 transmits data provided from the remote controller 10 to the key input determination unit 12. The key input determination unit 12 determines whether the received key data is a signal generated from the TV setting key 5 or the number key 6. The OSD character data output unit 14 outputs the TV manufacturer and model number to the OSD IC 15 in accordance with the determination signal transmitted from the key input determination unit 12. The OSD IC 15 receives the applied character data and inserts the character signal into the video signal to display the TV manufacturer and its model on the OSD screen.

The OSD on / off control unit 13 selectively controls data output from the OSD character output unit 14 according to the determination signal of the key input determination unit 12. That is, when the TV select key is pressed for the second time to set the selected manufacturer and model number, the display on the OSD is turned off after being delayed for a certain period of time, for example, 5 seconds according to the present invention. Therefore, the set number is displayed for 5 seconds and then disappears.

FIG. 3 shows a flowchart describing the operation performed by the remote controller 10 shown in FIG. 1, and the operation shown in this flowchart consists of the following two steps.

The first step (P1) is a processing process when the juter TV setting mode signal is applied as a key matrix, and the second step (P2) is a processing process when a number key signal for selecting a TV manufacturer and its model is applied.

In step P1, when the TV setting mode signal is input to the TV setting key input unit 1 (step S1), the flag state of the setting mode control unit 3 is determined (step S2). That is, if the TV mode flag currently has a value of 1, it indicates that the TV setting key 5 has been operated once, and if the TV mode flag has a current value of 0, the TV setting key 5 has been repeatedly operated off. It is judged to indicate the state. Therefore, if the TV setting mode signal is applied and the flag is set to 0, the flag value is set to 1 to make it possible to receive the number key input (step S3). However, if the flag is currently set to 1, it is determined that the TV setting key signal has been repeatedly applied, and the flag value is cleared to 0 to terminate the TV setting mode. Then, the read / write control unit 4 reads the manufacturer and model number previously stored in the storage unit 7 in accordance with the present invention and simultaneously stores the new number latched (step S5).

In step S6, TV setting key data including flag bits and data read by the read / write control unit are output.

In step P2, when the number key 6 is input (step S7), the state of the current TV mode flag is determined (step S8).

When the switch is turned on, the process proceeds to step S9 and the manufacturer and model number inputted are output as data. On the other hand, if the switch is in the off state, it handles the operation corresponding to the number keys performed in the normal remote control.

Referring to FIG. 4, the operation of the timer micom 20 for displaying the data output from FIG. 2 on the OSD screen will be described.

The flowchart shown in FIG. 4 is largely composed of two steps. The first step P3 is a process when the setting key data is transmitted from the remote controller 10 shown in FIG. 1, and the second step P4 is shown in FIG. This is the process when number key data is transmitted.

In step P3, when the key input determination unit 12 determines that the TV setting key data is (step S10), the state of the TV mode flag therein is determined (step S11). If the flag is 1, the flag is cleared to 0 (step S13), and the first data transmitted from the remote controller microcomputer 10 is output to the OSD IC 15 for a preset time, for example, about 5 seconds (step S14). And 15). However, if the flag is set to 0, its value is set to 1 (step S12).

In step P4, if it is determined that the number key is input (step S16), the set state of the flag is determined (step S17). If it is in the display mode state, the flow advances to step S18 to display the currently entered manufacturer number and model number on the OSD screen, and if it is not in the display mode state, the flow advances to step P3 again and repeats the above procedure.

As described above, the display function, which is not performed by the multi-function remote control without the display function, is displayed on the OSD screen using the OSD function, so that the user does not need to memorize how the manufacturer and model number have been selected in the past. According to the present invention, the operation can be simply checked by simply operating the TV setting key.
