Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a method for establishing a program and time of a remote controller (i.e., a (&#34;remocon&#34;), particularly to a method in which the program and time of the remocon are established, being seen by the attached liquid crystal display (LCD), and the established program and time are sent to the original VTR set, thereby establishing those of the VTR set. 
     In the past, in order to establish the program and time of the VTR with remocon, first the VTR set is turned on, and the user must establish the program and time of the VTR, watching display-characters on the screen, or operate manually the key of the VTR set. 
     Thus, the direct operation of the key is inconvenient and it is not found that the program and time are correctly established. 
     Also, in the prior method the program and time are established by watching on-screen characters, at first, the VTR set should be turned on, and the operation by remote control is therefore inconvenient. 
     SUMMARY OF THE INVENTION 
     The present invention has been made in consideration of this and has for one object to provide a method for establishing the program and time of the remocon, in which the established course of the program and time can be displayed by attaching the LCD to the remocon and the program and time of the original set are established by receiving that of the remocon when the desired program and time is completed. 
     Another object of the present invention is to provide the method in which the program and time established for the set can be performed, while watching only the LCD attached to the remocon without the operation of the key or on-screen characters since the LCD can display the established course of the program and time. 
     According to the present invention, there is provided a method for establishing the program and time of a remote controller having a microprocessor (i.e., a remocon MICOM) having remocon, characterized in that the time counting operation is performed being displayed on the LCD under the conditions that the initial time establishment is t1 seconds, the functional key is OFF and time more than t2 seconds goes by after the mode key is ON, and while not under these conditions, the conventional key input is sent as the remocon data after decoding of the key input, and mode key input is sent to the set as the remocon data for a mode-set after display on the LCD through the established route of each program and time.

     DETAILED DESCRIPTION OF THE INVENTION 
     The present invention will be now described in more detail with reference to accompanying drawings. 
     First, FIG. 1 represents the block diagram of the remocon with the LCD according to the present invention. 
     The remocon is constructed so that the clocks of the MICOM 2 for the main program and time are provided from the oscillators Z1 and Z2 of which have oscillating frequencies of 1.215 MHz and 32.768 KHz respectively, and the internal program the MICOM 2 is changed by pressing the key matrix 1, thereby establishing the program and time, with LCD 3 displaying the established program and time. 
     That is, after the program and time of the remocon is established by pressing the key matrix, the data of the remocon is sent to the original set, thereby establishing the program and time of the set. At this time, the established course is displayed on the LCD. 
     Thus, the user can establish and send the program and time of the remocon, watching the LCD3 attached to the remocon for establishing the program and time of the set. 
     Now, the program for establishing the program and time in the MICOM 2 will be described with reference to the FIG. 2 which represents the main flow chart. 
     When the initial main program starts, the RAM inside the MICOM 2 for the remocon is cleared, and the subroutine timers (1) (see FIG. 3) 1 and 3 have periods of 0.5 milliseconds and 1 seconds, respectively. At this time, the period of (see FIG. 4) timer 1, 0.5 ms, is obtained from the frequency of the oscillator Z1, 1.216 MH 3  and that of the timer 3, 1 sec, is obtained from that of the oscillator Z2, 32.768 KHz. 
     By distinguishing between time 1 and time 3 in the initial starting state after clearing of the RAM, if timer 1, then the decoding routine P1 for key input is performed, while if timer 3, then the count-up routine of the time at first is performed. After counting up the time, if the functional key of the key matrix 1 is ON, then the decoding routine of the key-input is first performed, while if the functional key is OFF, then whether the establishment, or setting, mode for the main program is selected is determined and if not, then the time setting mode is performed. 
     When the establishment, or setting, mode for the main program is ON, then, whether time more than 20 seconds goes by or not, is determined after the final key-input. But, if not in the establishment mode, then the routine directly enters into the oscillation stop routine of the oscillator Z1. 
     Also, the key-input decoding routine P1 is performed before 20 seconds go by. If twenty seconds have expire, the oscillation stop routine is performed. The routine begins to count the period of 20 seconds from the final key-input. 
     As this, when the timer 1 is selected or time more than 20 seconds does not go by on the establishment mode, the key-input decoding routine P1 is performed. The key-input decoding routine P1 will be described later. 
     On the other hand, if the routine is not in the establishment mode, then only time is counted. Thus, the oscillation of oscillator Z1 is stopped and the routine in which the decoding of the timer 1 is stopped, while the decoding of timer 3 is performed, also the interrupt 2 routine which is permitted, is performed. 
     Afterwards, the routine is performed whereby timer 1 is not decoded, while the timer 3 is decoded, also the interrupt 2 is permitted, if enters the standby state, checking the input state of the timer 3. If shown in FIG. 4 the subroutine of the timer 3 enters, then the subroutine shown in FIG. 4 is performed, while, if not, the counted time is displayed on the LCD. 
     At this time, if the subroutine is that shown in FIG. 5, the interrupt 2, is performed, the oscillator Z1 begins to operate and the subroutine timer 1 as shown in FIG. 3 is performed. Thus, the subroutine timer 1 distinguishes whether on sending of the remocon data or not remocon data is sent. If on sending, the remocon data as shown in FIG. 6 is sent, while if not, the counter for key-scan operates. After that time, all modes before the subroutine interrupt 2 are performed. The LCD 3 of the remocon displays the counted time. 
     Also, in case that the initial subroutine time 1 is selected, or the functional key is pressed, or that time more than 20 seconds does not go by during the establishment mode, the operation of the key-input decoding routine P1 is to be described. That is, in the key-input decoding routine P1, whether the key-input is the conventional number key or the sound multiselection key, is checked by decoding the key-input. This check of the key-input is finished if the key-scan pulse is double coincided when key-input enters. 
     At this, after the key-input is decoded in the key-input decoding routine P1, then whether the key-input is for establishment mode or not is determined. If the key is for the establishment mode, then whether the key-input is for main program establishment mode is again determined. 
     But, if the key input is not for the establishment mode, then the key-input is the conventional key-input so that the remocon data is sent to the original set. That is, if the key-input decoded in the key-input decoding routine is not the establishment mode key but the conventional functional key, the key-input is sent directly to the set so that the corresponding operation is performed. 
     But, if the establishment mode setting key is used, either the main program establishment mode or the time establishment mode is again distinguished. In case of the main program establishment mode, the main program establishment routine P2 is performed, while in case of the time establishment mode, the time establishment routine P3 is performed. 
     In the main program establishment routine P2, the main program can be established by receiving the key-input such as the program key, the recall/correct key for the reset and correction, the number key, the speed key for the tape, and the removal key. The establishment course of the main program by each key is displayed on the LCD 3. 
     And in the time establishment routine P3, the time is established by the clock key, the number key, and the recall/correct key. Also, the time establishment operation is displayed on the LCD. 
     At this, in both routines, that is, the main program establishment routine P2 and the time established routine P3, the establishment courses are displayed on the LCD 3, also whether the establishment operation is finished or not is determined. If the establishment of the main program and time is not finished, then the operation as mentioned above is repeated. 
     While, when the establishment of both is finished, the transmission key-input is checked so that the data is sent to the original set in case that the transmission key-input is entered. At this time, the LCD displays the established course regardless of the transmission key-input. 
     As above, when the main program and time are established and are sent to the set, the sent remocon data for establishment of the main program and time is constructed differently than the conventional functional data as shown in FIG. 6. 
     That is, the sent data of the conventional functional key is constructed as shown in FIG. 6(a), and the data for establishing the main program and time are constructed as shown in FIG. 6(b) and (c), respectively, where the establishment data is made up with many groups by regarding the conventional functional data of FIG. 6(a) as one group. Each group of the data for establishing the main program and time can be changed according to the establishment state, and the custom code of each group is identical with that of the conventional functional key. 
     As mentioned above, the present invention can establish simply the program and time of the set by sending the remocon data to the set after establishment of the remocon, and watching the displayed state on the LCD, where the data for establishing the main program and time are differently provided, and this different data is decoded in the original set for establishment of the set. Thus, the present invention is convenient for use, since the program and time of the set can be simply established by monitoring the LCD of the remocon. 
     The invention is in no way limited to the embodiment described hereinabove. Various modifications of disclosed embodiments as well as other embodiments of the invention will become apparent to persons skilled in the art upon reference to the description of the invention. It is therefore contemplated that the appended claims will cover any such modifications or embodiments as fall within the true scope of the invention.
