The present invention relates to jog / shuttle key operation on a remote control, to facilitate setting of initial value and change data value for menu data contents of various menu items such as clock display, program display and calendar display displayed on the CRT. To the operation of a jog / shuttle key.

In the remote control function associated with the conventional VCR, a calendar display, a clock display indicating the current time, and a program indicator indicating a reservation status when recording a program reservation are made to change the menu data contents of various menu items. In order to find the corresponding setting button on the remote controller and select it individually, the desired data value was changed.

For example, in a clock display item consisting of hour, minute, year, month, and day of the week, setting and changing the data value for the item can be selected by operating the +,-or 0-9 keys on the remote control. It will change the value.

Therefore, there is an inconvenience of having to find and operate an operation button in order to input the data value.

Accordingly, it is an object of the present invention to jog the setting of initial and change data values of selected menu item contents and item movement processing between data setting areas when the menu screen is displayed on the CRT in accordance with the operation of a menu key. It is intended to provide more convenience to the user by performing as / shuttle key.

In order to achieve the above object, the present invention provides a remote control receiver for receiving key data supplied from a remote controller equipped with a jog / shuttle key, and the key data has a noise with respect to the key data supplied from the remote controller receiver. And a key input processing unit for performing key input processing on the input of the normal key data after determining whether the key data is normal, and when the key data supplied from the key input processing unit is a menu key, a jog key, and a shuttle key signal, A key input classification unit for supplying each key signal to each corresponding key processing unit, and the key signal classified and supplied from the key input classification unit is a jog key signal. A jog key input processing unit for converting and outputting an initial value and a changed data value; And a shuttle key input processing unit for converting the shuttle key signal into an item moving processing signal between data setting areas of the selected menu item content and outputting the converted key signal, when the key signal is classified and supplied from the key input classification unit. When the classified and supplied key signal is a menu key signal, processing is performed from a menu key input processing unit for converting the menu key signal into menu screen data and outputting the same, and the jog key input processing unit, shuttle key input processing unit, and menu key input processing unit. And an OSD screen data processing unit for converting the supplied key signal into a corresponding character on the CRT or an item moving processing signal between data setting areas.

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

BRIEF DESCRIPTION OF THE DRAWINGS The figure shows a block diagram illustrating the performance of key input processing in accordance with jog / shuttle key operation to achieve the object of the present invention. First, when a menu key signal is supplied to the remote controller receiver 1 according to a user's remote controller key operation, the remote controller receiver 1 transmits the menu key signal through a line 2 to a key input processor (inside the timer microcomputer 3). 7). At this time, the key input processing unit 7 determines whether the menu key signal is a normal key data signal instead of a noise. When the key data is found to be a normal key data signal on a remote controller, the menu key signal is connected to a line ( It is supplied to the key input classification unit 9 through 4). 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, jog key, or shuttle key signal, and supplies the determined key signals to the corresponding key input processing unit. If the currently supplied signal is a menu key signal, the key signal is input to the menu key input processing unit 15, and if the jog key signal is the jog key input processing unit 11, and if the shuttle key signal is the shuttle key input processing unit 13, the key signal is transmitted. Will be supplied. Therefore, since the currently supplied key data is a menu key signal, the menu key signal is supplied to the menu key input processor 15 through the line 10. The menu key input processing unit 15 converts the menu key signal into menu screen data and supplies the same to the OSD screen data processing unit 5 through the line 16. The OSD screen data processing unit 5 is provided with a line ( 18) the menu screen data is converted into the corresponding characters on the CRT and output. 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 process of moving items between the initial value, the changed data value and the data setting area for the selected menu item contents is operated by the jog shuttle key.

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

Therefore, when the jog key signal is supplied to the remote controller receiving unit 1, the jog key signal is supplied to the key input classification unit 9 through the key input processing unit 7. Then, the key input classification unit 9 supplies the jog key signal according to the key classification procedure to the jog key input processing unit 11 through the line 6, and the jog key input processing unit 11 supplies the jog key signal. Is converted into an initial value and a change data value of the selected menu data contents and supplied to the OSD screen data processor 5 through the line 12. Therefore, the initial value and the change data value for the menu item contents are changed into corresponding characters on the CRT by the OSD screen data processing unit 5 and displayed on the line 18 in the data setting area on the CRT.

Incidentally, the item moving process between the data setting areas for the contents of the menu item 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 classifier 9 through the remote controller receiver 1 and the key input processor 7, the key input classifier 9 performs the shuttle according to the key classification procedure. The key signal is supplied to the shuttle key input processing unit 13 through 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 data setting regions and converts the OSD screen data processing unit 5 through the line 14. To be supplied. Then, the OSD screen data processing unit 5 converts the item movement processing signal between the data setting areas supplied from the shuttle key input processing unit 13 into the form of a cursor and displays it on the CRT through the line 18. Therefore, the cursor moves to the desired data setting area according to the shuttle key signal supplied to the remote controller receiver 1.

As described above, the present invention performs the clock display or program indicator menu item contents by performing an item moving process between the initial value and the changed data value and the data setting area of the selected menu item contents according to the jog / shuttle key operation while viewing the CRT screen. This has the advantage that it is very convenient to set up the data for.
