The present invention relates to a technique for simplifying the key operation in consideration of the front and back correlation of the key operation, and in particular, to determine which key signal will be input after the currently input key signal based on the correlation of the previously input key. The present invention relates to a method of inferring a driving key of V-Cal which is suitable for presenting and deciding whether or not to execute the proposed key command according to a user's judgment.

In the case of a general VRL, when you record a desired program on a tape or play a recorded program, you need to press forward fast or rewind key to find the desired starting point on the tape, press the stop key, and then press the play or record key. Operation was accompanied by a lot of cumbersome, more practically a lot of use at night, the surroundings were generally dark, it was more difficult to find the key.

Accordingly, an object of the present invention is to sequentially store a user's key input operation sequence in a memory, check the input frequency of the key input after the current mode, and present the key with the highest frequency and execute the suggested key command. It provides a way to execute the command by typing.

The driving key input inference method of the present invention for achieving the above object is a tenth step (S10) for confirming that the key signal related to the running of the tape is input, and the 20th step for performing the corresponding function when the driving key is input; (S20), the thirtieth step S30 of sequentially storing the input driving key; and the forty-step step S40 of inferring the driving key to be input after the current mode based on the stored driving key; In operation 50, the controller determines whether the inference key is input and executes a function corresponding to the inferred driving key.

FIG. 1 is a block diagram of V-C to which the driving key input inference method of the present invention is applied. As shown in FIG. 1, a remote controller outputs control signals for controlling various functions of V-C, including control signals related to running of the tape. (1), an infrared receiver 2 for receiving a near infrared signal output from the remote controller 1, and various control signals for performing a corresponding function according to various control signals inputted through the infrared receiver 2; A microcomputer 3 for outputting, inferring and displaying the driving key to be input next to the current mode when the inference key is input, and performing a function corresponding to the inferred key again when the inference key is input, and the micro The servo system 4 is configured to control the drive of the deck system 5 under the control of the computer 3 to perform a tape playback or recording function. The present invention configured as described above will be described in detail with reference to FIGS. 2 to 7.

First, when a viewer wants to record a desired program on a tape or to play a program already recorded, as shown in FIG. 2, driving-related keys, that is, a rewind key (REW), a play key (PLAY), and a fast forward driving key (FF), The desired function is selected by using the remote controller 1 composed of a STOP key, a reasoning key 1A, other channel keys, and a number key. For example, when a PLAY key is selected, The infrared signal of a predetermined type output from the remote controller 1 is transmitted to the microcomputer 3 through the infrared receiver 2.

The microcomputer 3 checks that the current playback key PLAY is input based on the infrared signal inputted through the infrared receiver 3 (S10), and opens the deck system 5 through the servo system 4. Since the playback mode is controlled, the playback function is performed. (S20)

At this time, the microcomputer 3 stores the input play key PLAY in a predetermined memory, and stores the key sequentially in the order of input whenever a key signal related to the driving is input. (S30)

3A shows various types of driving keys sequentially stored by the above-described process. The reason for storing the driving keys input as described above is inferred data when the inference key 1A is input. This is for use in inferring driving keys which are expected to be input.

The microcomputer 3 checks the frequency of the key input after the current mode by checking the various driving keys stored in the memory, selects the key with the highest frequency as the key to be input next, and displays it externally. For example, if the current mode is the playback mode as described above, as shown in (a) and (b) of FIG. 3, the play key PLAY is input, and then the stop key STOP is entered once, but other keys are not input. Since the next time the user expects to enter the STOP key (STOP), it displays the STOP on the external display window or LCD (S40).

Thereafter, the microcomputer 3 checks whether the inference key signal 1A is input through the above path (S40), that is, when the inference key 1A is displayed in the state where STOP is displayed as in the above example. If is inputted, the process returns to the twentieth step S20 and performs the stop function, and repeats the subsequent process. If not, the process returns to the initial state and repeats the above process.

On the other hand, each of the step-by-step process is described in more detail with reference to Figures 5 to 7 as follows.

First, referring to FIG. 5, a thirty-step step S30 of storing driving key data to be stored in a memory will be described. Once a driving-related key is input, the address of the memory is increased by one (S31), and the address is increased. The driving key data is stored (S32). After checking whether the current address reaches the preset N address (S32), if the address is reached, the address is set to 0 and terminated.

Although FIG. 5 shows a series of storage processes for storing driving-related key data over a preset N times, the driving-related key data is stored in a serial shift method so that the latest driving key input habits can always be grasped so that more accurate inference can be obtained. This becomes possible.

Referring to FIG. 6, when the driving key inference step S40 is described, the address of the memory is increased by one (S41), and the driving key data stored at the address is read (S42), and the key is the same driving key as the current mode. If the same driving key is checked (S43), an additional address is increased to determine which driving key is input next (S44), and the driving key data stored at the address is read (S45). S46)

Thereafter, the address is increased by one (S47), the address is increased by checking whether N + 1 is reached (S48), and the above process is repeated until the address is reached, and the N + 1 is reached. If it is, the driving key inputted after the current mode is set the most and the displayed driving key is displayed on the external display window or LCD.

(A) and (B) of FIG. 3 exemplarily illustrate the above-described implementation process. When the driving-related key data is stored in the memory as shown in FIG. In the next mode, the driving key input frequency is detected as shown in (b) of FIG. Here, when a plurality of driving key data is detected the same number of times, a key having a predetermined priority is set and displayed.

Referring to FIG. 50, when the inferred key is executed with reference to FIG. 7, the user checks whether the user inputs the inference key 1A in order to use the inference key function (S51). Display the driving key inferred through the same process as in (S51), and starts the counter (S53).

Thereafter, the controller checks whether the inference key signal is input again within a predetermined time (for example, 3 seconds), and if it is input, performs the corresponding function, and if it is not input, cancels the display function.

For example, if the user presses the play key (PLAY), the play function is executed, and if the user presses the reasoning key 1A to use the reasoning function at any time, the stop key STOP is generated by the above process. Is displayed. At this time, if the user wants to execute the stop function, pressing the inference key (1A) again, the stop function is performed immediately, and if the inferred key does not correspond to the desired key, the user inputs another function key. The reasoning function is immediately released. For reference, the reasoning function of the present invention is used in parallel with the existing key input means.

As described in detail above, the present invention sequentially stores the user's key input operation sequence in the memory, checks the input frequency of the key input after the current mode, and presents the most frequent key keys and the suggested key commands. By executing the command by checking whether the execution of the has the effect that can provide convenience to the user.
