The present invention relates to a technology for returning to a previous mode from V-Cal. In particular, when an undesired mode is selected due to a user's mistake, the V-Cal's cancellation input is adapted to receive a cancel key input and to switch to a setting state of the previous mode. It relates to a treatment method.

1 is a diagram showing various keys of a remote controller applied to a general V-Cal for convenience of explanation, and as shown in FIG. 1, rewind key (REW), play key (PLAY), fast driving key (FF), and the like. It is composed of PAUSE, STOP key, STOP key, REC key, REC key, and the first group key G1 for controlling the driving of deck system, power key, input selection key, volume up / down key, channel The second group key (G2) which consists of increase / decrease key, clock / counter key, and toggles on, off or up / down, numeric key, G code key, function selection key, learning reservation key, simple reservation key, It consists of help key, channel memorization / clear key, input channel input number, input number on menu, and it is connected to third group key (G3) for reservation. Referring to Figure 3 as follows.

First, the processing method of the first group key G1 will be described. For example, while listening to a program recorded on a tape, pressing the stop key to stop listening to a program on the way, and then watching the program again from the point where it stopped. If you press the play key (PLAY) by mistake, but you press the fast drive key (FF) by mistake, the loading motor is driven by controlling the deck system after the system control microcomputer (not shown) recognizes the high-speed drive key (FF). The drum motor and the capstan motor are rotated at high speed, and at this time, the running counter of the tape is operated to display the running distance of the tape.

After a predetermined time has elapsed, if the user notices a mistake and wants to return the running position of the tape to the original position, that is, the stop position before the high-speed driving is executed, the count value is stored and then rewinded. And the stop key can be used to return to the original position. However, in most cases, the user does not remember the count value. In such a case, the user presses the stop key when the desired position is reached while searching the screen using the fast search key.

Referring to the processing of the second group key (G2), when the user presses the play key to listen to the program and accidentally presses the power key, the power is turned off after the stationary mode is performed in the deck system. Appears on the external LCD. At this time, the user should press the power key again after pressing the power key in order to return to the original playback mode from the current power off mode after recognizing his mistake.

If you press the channel up / down key incorrectly, you can return to the original channel by using the previous channel key. However, the input selection key operates in the toggle mode, so if the number of inputs is 4 ~ 5, you need to press 3 ~ 4 times. You can return to input mode again. For example, if the input is ① wired broadcasting, ② general broadcasting, ③ external input, ④ external input 2, ① you want to select the cable broadcasting, but if you select ② general broadcasting by mistake, select the input selection key 3 times (② → ③ → ④ → ①) You should press it.

The process of processing the third group key (G3) will be explained. In the case of accepting the reservation by toggle method by displaying the reservation recording input table on the screen, as shown in FIG. The menu screen showing the type is displayed. For example, press button # 3 to select the sub-menu screen, select the scheduled recording for one program, set the channel, start time, and end time, and then schedule another program again. In order to cancel the reservation recording function itself, press and hold the function selection key to exit the screen state of each step.

However, in such a general V key processing method, when the control key is input by mistake, the immediately previous mode data is replaced with the data of the current mode. Therefore, in order to return to the home position, the key has to be manipulated several times, so that it is time-consuming and time-consuming, and moreover, a child or an elderly person who is inexperienced in the key operation has emerged as a combination that causes confusion in use.

Accordingly, an object of the present invention is to provide a method for automatically switching to a setting state of a previous mode by receiving a cancel key input when an undesired mode is selected due to a user's mistake.

In order to achieve the above object, the VRF cancel input processing method of the present invention scans various control key signals inputted from the key input means to store the current mode when the key signal is input and to store the state data of the current mode. After the first step of performing a function corresponding to the corresponding control key signal, and implements a new mode function in response to the new key input, when the cancel key signal is input, it switches to the stored mode and returns to the state Including the second process.

4 is a schematic block diagram of V-C to which the cancellation input processing method of the present invention is applied, and as shown in FIG. 4, a remote controller for outputting various control key signals and a mode selection cancel key signal for controlling each part of the V-Cal; 1) and the overall control of the V-CAL system under the control of the remote controller 1, and each time various key signals are input, the current mode and its state are stored in a separate buffer, A microcomputer 2 for switching to the stored mode and state when the mode selection key signal is input, and a servo system 3 for controlling the driving of the deck system under the control of the microcomputer 2, and A deck system 4 which reproduces and outputs a program recorded on a tape under the control of the servo system 3 or records a program input from the outside, and an image reproduced by the deck system 4. Arc or when supplied to the video signal (Vin) is input from the outside was composed of a video signal processing unit 5 for processing so as to suitable for display on the display means.

5 is a schematic view of the remote control showing the installation portion of the cancel key of the present invention, and added the cancel key (1A) (Undo key) to the existing key group (G1-G3) as shown in FIG. Conveniently installed in the middle of the right side of the remote control 1, and formed larger than the general key, with reference to Figure 6 attached to the operation and effect of the present invention configured as described above in detail as follows.

First, the processing method of the first group key G1 will be described. For example, while executing the playback mode, the program is recorded on the tape and the stop key is pressed in order to stop watching the program. When pressing (FF), the microcomputer 2 recognizes the key input and stores the playback mode and the tape travel distance, which are the immediately preceding modes, in separate buffers before performing the high-speed driving.

Thereafter, the microcomputer 2 controls the deck system 4 through the servo system 3 so that the loading motor is driven, the drum motor and the capstan motor are rotated at high speed, and the running counter of the tape operates to drive the tape travel distance. Is displayed. At this time, when the user recognizes a mistake and presses the cancel key 1A, the microcomputer 2 recognizes the key, reads the tape travel distance stored in the buffer, drives the tape to the position, and returns to the playback mode. do.

Accordingly, the user can skip the cumbersome key operation in order to return to the previous mode and driving position, and the cancel key 1A is the same in other modes, namely, rewind, fast driving, pause, stop, and recording mode. Is applied.

For example, a process of processing the second group key G2 will be described. If a user presses a play key to watch a program and accidentally presses a power key, the microcomputer 2 recognizes the key input and powers off as described above. Before executing the function, the previous mode, the playback mode and the tape mileage, are stored in separate buffers.

Then, after the stop mode is performed in the deck system 4, the power is turned off, and the power-off state appears on the external LCD. At this time, when the user recognizes his mistake and presses the cancel key 1A, the microcomputer 2 recognizes the key and reads the tape travel distance stored in the buffer to drive the tape to the location. Return to the mode.

As another example, when there is ① wired broadcasting, ② general broadcasting, ③ external input 1, ④ external input 2, ① attempting to select wired broadcasting but accidentally selecting ② general broadcasting, the previous input (① wired broadcasting) as above. ) Is stored in a separate buffer and another input is selected, and when the cancel key 1A is input as above, it toggles as in the prior art and recognizes the stored input and selects it immediately before selecting another input sequentially. You can select the input (① wired broadcast) that you have used. Referring to the processing of the third group key G3, for example, in the case of a method of accepting a reservation by a toggle method by displaying a reservation recording input table on the screen, as shown in FIG. A menu screen indicating the type of reserved recording is displayed. For example, by pressing ③, the submenu screen is selected to select the reserved recording of one program, set the channel, start time, end time, and the like. In order to reserve recording, press ③key and then set as above. If you press the cancel key 1A to cancel the reservation recording function, the microcomputer 2 recognizes the key and then stores it in the buffer. The normal display mode is read and you are returned to that mode.

As described in detail above, the present invention allows the user to automatically switch to the setting state of the previous mode by receiving a cancel key input when an undesired mode is selected due to a user's mistake, thereby avoiding the troublesome operation of the key. This saves time.
