Description

Digital jog processing method

The present invention relates to a jog shuttle system widely applied to a video apparatus such as a Vial, and more particularly to a digital jog processing method using a temporal continuous key processing method which does not require a series of pattern structures to detect movement of a jog key .

For example, the jog shuttle function in Vishal etc. provides various convenience in using Vishial in addition to searching for the playback screen, which is a representative function of the jog shuttle function.

In case of changing the menu data contents of various menu items such as the calendar display, the time display indicating the current time, and the program display showing the reservation status at the time of program reservation recording in the remote control function related to the vial, And the change of the desired data value is performed by selecting the corresponding setting button and selecting one by one.

For example, in the clock item display made up of hour, minute, year, month, day, and day, setting and changing of the data value for the item can be performed by operating the plus / minus or numeric keys on the remote controller, Can be changed.

FIG. 1 shows a processing circuit of a jog shuttle key input signal.

As will be referred to here, the signal processing circuit includes a remote control receiver 1 for receiving key data supplied from a remote controller equipped with a jog / shuttle key, and a controller for receiving the key data supplied from the remote controller receiver 1, A key input processing unit 7 for determining whether data is normal key data, not noise, and then performing a key input process for inputting normal key data, and a normal key data supplied from the key input processing unit 7, A key input classifier 9 for supplying the respective key signals to respective corresponding key processing units when the key signal is a jog key and a shuttle key signal, A jog key input processor 11 for converting the jog dial signal into an initial value and a changed data value for the selected menu item and outputting the converted value, And a shuttle key for converting the shuttle key signal into an item movement process signal between data setting areas for the contents of the selected menu item and outputting the shuttle key signal when the key signal supplied from the key input classifying unit 9 is a shuttle key signal, A menu key input processor 15 for converting the menu key signal into menu screen data and outputting the menu key data when the key data supplied from the input processor 13 and the key input classifier 9 is a menu key signal, The key data supplied from the jog key input processing unit 11, the shuttle key input processing unit 13, and the menu key input processing unit 15 are converted into corresponding characters on the CRT or converted into item movement processing between data setting areas And an OSD screen data processing unit 5.

The operation of the jog shuttle circuit constructed as described above will now be described.

First, when a menu key signal is supplied to the remote control receiver 1 in response to a user's remote control key operation, the remote control receiver 1 receives the menu key signal through the line 2, 7). At this time, the key input processing unit 7 determines whether the menu key signal is a normal key data signal, not noise. If the key data is determined to be a normal key data signal on the remote controller, To the key input classification unit 9 through the key input unit 9. Then, the key input classification unit 9 determines whether the normal key data supplied from the key input processing unit 7 is a menu key, a jog key or a shuttle key signal, and supplies each key signal discriminated to the key input processing unit If the currently supplied signal is a menu key signal, it is transmitted to the menu key input processing unit 15, the jog key input processing unit 11 if the jog key signal is a signal, and the shuttle key input processing unit 13 if the signal is a shuttle key signal. Signal. Therefore, since the currently supplied key data is the menu key signal, the menu key signal is supplied to the menu key input processing unit 15 through the line 10. The menu key input processing unit 15 converts the menu key signal into menu screen data and supplies the converted menu screen data to the OSD screen data processing unit 5 through the line 16. The OSD screen data processing unit 5 processes the menu screen data, 18 to convert the menu screen data into corresponding characters on the CRT and output the corresponding characters. Therefore, the menu item to be selected is displayed on the menu screen on the CRT.

When the menu screen is displayed on the CRT as described above, the item movement process between the initial value, the change data value, and the data setting area for the content of the selected menu item is activated by the jog shuttle key.

For example, when a clock display item, which is a menu item on the CRT, is selected, initial setting and change of menu data contents of hour, minute, year, month and day are performed according to the jog key, The item movement process between the municipal station, the minute zone, the year zone, the month zone and the day zone is performed according to the shuttle key.

Accordingly, when the jog key signal is supplied to the remote control receiver 1, the jog key signal is supplied to the key input classifier 9 through the key input processor 7. The key input classification unit 9 then supplies the jog key signal to the jog key input processing unit 11 through the line 6 in accordance with the key sorting procedure. In the jog key input processing unit 11, Signal to the initial value and the changed data value of the selected menu data contents and supplies the converted data value to the OSD screen data processing unit 5 through the line 12. Therefore, the initial value and the changed data value of the menu item contents are converted into corresponding characters on the CRT by the OSD screen data processing unit 5 and displayed on the CRT through the line 18 as the data setting area on the CRT.

The item movement process between the data setting areas for the menu item contents on the CRT is performed by the shuttle key signal as follows. When the shuttle key signal supplied from the remote controller is supplied to the key input classifying section 9 via the remote control receiving section 1 and the key input processing section 7, And supplies the key signal to the shuttle key input processing unit 13 via the line 8. [ Then, the shuttle key input processing unit 13 converts the shuttle key signal supplied from the key input classification unit 9 into an item movement processing signal between the data setting areas, and outputs the item movement processing signal to the OSD screen data processing unit 5 through the line 14. [ . Then, the OSD screen data processing unit 5 converts the item movement processing signal between the data setting area supplied from the shuttle key input processing unit 13 into a cursor shape and displays it on the CRT through the line 18. [ Accordingly, the cursor moves to the desired data setting area according to the shuttle key signal supplied to the remote control receiver 1. [

Accordingly, it is possible to perform an item movement process between the initial value of the contents of the menu item selected and the change data value and the data setting area according to the operation of the jog / shuttle key while viewing the television screen, The data setting operation for the contents can be performed very conveniently. However, when the key input is continuously inputted in the operability thereof, the user has to inconvenience that the corresponding key must be entered.

It is an object of the present invention to provide a digital jog processing method of a continuous key input processing method which will be followed by a time variation in which a large amount of jog pattern areas required for grasping the amount of jog in a jog shuttle apparatus can be minimized.

A feature of the present invention is that the method includes judging a jog input based on whether a single contact jog pattern of the forward and backward positions to be positioned opposite to each other to be selected by movement of the jog shuttle adjustment base is switched on, Executing a timing count (t) during the forward and backward jog key input times by the timing counter (t) and stopping the screen frame until the value reaches the first set time value (T1) And further advances the step by advancing the screen frame at regular intervals until the value reaches the second set time value T. The method further includes the step of: (T), disabling the continuous jog key input and switching the video equipment to the normal playback mode.

BRIEF DESCRIPTION OF THE DRAWINGS Fig.

FIG. 2 is a structural view of a jog shuttle apparatus to be applied to the present invention. On the substrate 20, a shuttle pattern 25 and a jog pattern 26 for forward and backward are provided.

The shuttle pattern 25 is formed by a combination of a plurality of patterns having a predetermined interval, and the jog pattern 26 is formed as a single contact for determining the presence or absence of a jog.

The frame 21 is arranged in accordance with the pattern on the substrate 20 as described above.

The frame 21 is provided with a second guide 29 in the up and down direction and a first guide 28 in the left and right direction.

A jog shuttle base 22 is disposed at a center portion formed by the first and second guides 28 and 29.

The shuttle contact 23 to be brought into contact with the shuttle pattern 25 and the jog contact 24 to turn on / off the jog pattern 26 are formed on the jog shuttle base 22.

FIG. 3 is a block diagram of a jog control system for implementing the present invention. The jog selection signal to be generated from the apparatus of FIG. 2 is input to a microcomputer 30 having a timer 32 via a jog- And the deck control unit 33 is controlled by the output of the microcomputer 30 so as to be connected.

A digital jog processing method to be executed based on the basic hardware configuration will be described with reference to FIGS. 2 to 5.

When the jog contact base 24 is moved up and down in the drawing to contact the jog pattern 26, the jog key input unit 31 of the third degree transmits it to the microcomputer 30.

Thus, the microcomputer 30 outputs a control signal to the deck control unit 33 as a timing control value by the timer 32.

At this time, the microcomputer 30 executes a program shown in FIG. 4. First, it is determined whether or not a jog key is input. If there is no key input, the timer counts the timer count by the timer 32 and then ends. It is judged whether it is a forward (FF) jog mode or a backward (REW) jog mode,

The forward jog mode and the backward jog mode program are selectively executed.

5 is a sub-routine program of the forward (FF) jog mode. When the forward jog mode execution is started, the timer executes the timing count t while the jog key is depressed and determines whether the value reaches the first set value T1 .

Here, if the current timing count value t has not reached the first set value T1, the microcomputer sets the jog mode to the screen frame stop mode as intended by the operator.

However, when the timing count value t reaches the first set value T1, the microcomputer controls the deck unit to switch to the step advancing mode for advancing at a predetermined time interval.

If the timing count value t reaches the second preset time value T2, the microcomputer ignores the jog key even if the jog key is input, thereby avoiding a burden imposed on the video device from unreasonable jog input.

As described above, according to the present invention, it is possible to minimize an area occupied by a plurality of jog patterns in an image device having a jog function, and also to reduce the operation load of the image device due to unreasonable jog key input.
