The present invention records the desired message in the NV RAM of the video device (VTR, TV), and when the predetermined time comes, the content of the message recorded at the predetermined time using the ON SCREEN DISPLAY function and the alarm function. It relates to a message memory and a display method of an image device to display.

In other words, even if the power is not supplied, the user can store the messages he / she wants (appointment time, celebration day, etc.) by using NV RAM which can memorize the memory contents permanently, and then use the OSD function and alarm function. By displaying a message externally at a time, a user can use an image device as an electronic organizer.

In the conventional similar function, the appointment time is memorized by using the memory of the imaging device, and when the predetermined appointment time is reached, the image device is turned "on" or an alarm function is provided to notify the user that the appointment time is reached, The on / off time was reserved to utilize the function of automatically turning the "on" "off" image device at the reserved time.

However, when using this function, if the power is cut off or a power failure occurs, all memory functions of the set will be reset, which will not inform the appointment time, etc. I was not sure if the alarm function was activated.

Therefore, it was necessary to memorize and display more various information by using RAM that can memorize the contents even in the state of power failure.

For example, when the appointment time arrives, the alarm function is activated to inform the outside, and the OSD function should be displayed in a simple memo form to indicate who and where to meet on the screen.

To this end, in the present invention, the memory stored in the memory by the power failure, etc. is not reset by using the NV RAM and the user desired time and various messages after the user's desired time using the alarm function and at the same time using the OSD function The message that the user has memorized is displayed in the proper format.

The NV RAM used in the present invention is currently expensive and low in memory capacity, but it is expected that the memory capacity of the NV RAM can be greatly expanded and reduced in price through technology development. It is about how to use NV RAM equipped.

As described above, the present invention will be described in detail with reference to the accompanying drawings in which various messages are stored in the NV RAM and displayed at a desired time using an OSD function together with an alarm function in a suitable format.

First, the driving method of the OSD, which is the display form according to the present invention, will be described with reference to FIG.

In order to display the OSD, the microcomputer 1 shown in FIG. 1A outputs an active low chip select signal to the OSD block 2, followed by the data and the address according to the clock. That is, a signal relating to the character and the position where it is to be displayed on the image is output from the microcomputer 1 to the OSD block 2.

For example, when displaying the character HAPPY DAY on the screen, the data output of the microcomputer 1 should be output as shown in FIG. 1B, and the positions of "H" and "D" are determined by the address, The HAPPY DAY character is displayed.

Meanwhile, in the present invention, the processing for the message text input from the user is performed based on the flowchart shown in FIG.

First, when the problem data is input by the user, the character data is classified and the OSD program is processed for the input data and the text data is output to display the OSD on the screen.

That is, if the character data input by the user is present, the OSD program for the data is processed and the OSD is displayed at the same time, and the character data is stored in the NV RAM, and the character data stored in the NV RAM exceeds the memory capacity. If not, move the cursor indicating the character input position in the OSD screen to prepare for the next character input, but if the memory capacity of NV RAM is exceeded, display “OVER”, the memory capacity indication on the screen, Do not accept character data input.

Thus, the program selection operation of the present invention for processing the input character data based on the flowchart of FIG. 2 will be described based on FIG.

First, the present invention selects an electronic notebook (ELECTRONIC MEMO) function that can record various messages on the OSD menu screen displayed when a program key is input, and stores the text data. This process is reserved through the OSD menu screen with a conventional remote controller. It's almost like setting up a program.

That is, the present invention selects the ELECTRONIC MEMO function and stores the text data in a manner similar to the method of reserving the OSD by viewing the OSD display with the remote controller. The OSD menu screen is displayed as shown on the right side of the figure, wherein numbers 1-4 indicate the selection of a reserved program to be performed and number 5 becomes the electronic notebook selection function of the present invention.

Therefore, the user presses the number 5 on the remote control to select the electronic notebook mode of the present invention after the user presses the program button on the remote control so that 1-5 years is displayed on the OSD menu screen as shown on the right side of the drawing. MEMO) is selected, and three menus, which are internal functions of the organizer, are displayed again.

Therefore, when the user presses the program button and presses the organizer selection number 5, the menu of the organizer is displayed in three ways, so the user presses the required menu number among the organizer menus and inputs a message according to the selected menu. After the message input is completed, the message input of the organizer menu is completed by "off" the OSD in the same manner as the "off" of the existing OSD.

At this time, the digital organizer menu appearing on the screen B of FIG. 3 may be extended by adding any number according to memory capacity such as an address book, a directory, and a phone book.

In this way, if you press the program number of the program selection number on the screen by pressing the program key, the electronic notebook menu screen as shown in (B) of Fig. 3 is displayed. Look at the diagram.

That is, when the user presses 1 to select HAPPY DAY, the screen shown in FIG. 4A is displayed on the OSD screen.

At this time, the format displayed as the screen of FIG. 4A can be changed to another format, and four program numbers can be expanded according to memory capacity.

In the screen of FIG. 4A, the number of the already selected and reserved records among the four program numbers easily indicates which program is selectable by not blinking.

In other words, four programs can be selected to select four congratulatory days to memorize the message.

For example, if there is no program reservation, after the screen of FIG. 4a is displayed and the program 1 is selected by pressing No. 1 key on the remote controller, the OSD screen is displayed in the same format as in FIG. 4b.

In this case, the blinking cursor (C) is a guide for writing a character, and moves one space each time character data is inputted one by one, and indicates the space where the next character data is to be input. The screen format of FIG. 4b can be changed to another ideal format. Do.

When the screen is displayed as shown in FIG. 4B, the user can change the time (FROM) and the ending time (TO) for sending the alarm signal using the movement of the cursor (C)-/-/-/-( Year / Month / Day / Time), and after the alarm time is set, the message entered by the user is memorized from the next column to the capacity allowed by the memory.

Character data input at this time follows the flowchart of FIG.

In this way, the user selects the electronic organizer menu (Fig. 3 (B) 1 (Fig. 4a) and selects a program available for reservation (Fig. 4b) to alarm the birthday or other anniversary that the user should remember. In addition, by recording the text data as a message, the user can recognize the contents of the message displayed by the alarm function and the OSD function at the desired time.

On the other hand, in order to record the appointment time and the contents of the appointment in the electronic notebook, when the screen (B) of FIG. 3 is displayed, press 2 to select PROMISE, and the OSD screen is displayed as shown in FIG. 4C.

At this time, the screen display format as shown in FIG. 4C can be changed as much as possible, and the program number used among the programs 1, 2, 3, and 4 is not blocked.

Therefore, when the user selects the recordable program number to be blinked by looking at the OSD screen as shown in FIG. 4C (select 1 in the present invention), the screen as shown in FIG. 4D is displayed on the OSD screen.

At this time, the screen format as shown in FIG. 4d may be changed, and the cursor C at this time is the same as the cursor operation in FIG. 4b.

Therefore, the user sets the start time (FROM) and the end time (TO) of the alarm time according to the movement of the cursor (C) by using the remote control keys, and then the appointment time (WHEN), appointment place (WHERE), The WHO, WHY, etc. are stored as simple text data.

That is, when the screen is displayed as shown in FIG. 4d for setting the message of the appointment, the alarm time and the end time are set according to the movement of the cursor C, and a simple appointment message is made.

As shown in (B) of FIG. 3, when the memo (MEMO) is selected by pressing 3 when the detailed menu program of the electronic notebook is displayed, the OSD screen is displayed in the same format as in FIG. 4E.

At this time, the program format can be changed as many times as described above. When the program 1, 2, 3, or 4 programs are recorded, the user does not blink and selects a program number that is not recorded.

In this case, when the user selects No. 2, the display is displayed as shown in FIG. 4f, and the format can also be changed, and the cursor C guides the position where the input character data is displayed as described above.

Therefore, the user sets the start time FROM and the end time TO of the alarm time according to the movement of the cursor C on the screen display as shown in FIG.

In the MEMO mode, memo characters are memorized, which requires a significant amount of memory, but this can greatly increase the memory capacity.

If the allocated memory capacity of the NV RAM used for each menu is exceeded for the message input for each program menu of the ELECTRONIC MEMO as described above, the capacity of the memory is displayed by displaying the word “OVER” on the OSD screen. At the same time, the cursor does not move and no text data is input.

That is, as in the character input flowchart of FIG. 2, when the character data input exceeds the memory capacity, the screen displays “OVER” to inform the user. When the user deletes the character data (Delete), the memory is erased as much as the erased data. The "OVER" display disappears as it remains.

As described above, the message input of the desired program in the electronic organizer menu has been described. Next, the memory message contents will be described when the scheduled alarm time comes. When the scheduled reminder time of HAPPY DAY is reached, the alarm is displayed and the screen is displayed as shown in FIG. 5A. Also, when the appointment time of the PROMISE is reached, as shown in FIG. 5B, the memo ( When the reservation time of MEMO) is reached, as shown in FIG. 5C.

At this time, each display format can be changed to another format and when the program key is pressed, the entire OSD screen disappears.

Therefore, when the alarm time is set as shown in Figs. 5a, b, and c, the user displays the alarm and displays the message contents (displayed as xxx in the drawing) that the user memorizes. do.

That is, the user simply uses the electronic organizer function of the image device by displaying a simple message on the screen why the time is set instead of simply displaying the set time as an alarm.

In this way, the OSD display of each mode of the organizer prevents the imager from performing an alarm function during recording or rewinding, and only when it is within the set time range during normal operation (during playback). The OSD is displayed together, and this performing operation is the same as the flowchart of FIG.

In other words, it checks which mode is recorded in NV RAM to continuously detect whether the recorded alarm time is reached, and when the set time is reached, it is possible to check whether or not the video device can perform OSD instead of performing special function. If it is not in the OSD mode, it is still waiting.

If it is the set time and it is possible to perform OSD, it is judged whether the power is "on" and when the power is "on", it performs the OSD function with the alarm function. And program key are entered.

At this time, if the power is "off" in a situation where the OSD may be performed, the above operation is performed after the power is "on".

If the set time has elapsed during the execution of the alarm and OSD function, or if a program key is input, the alarm and OSD function will be stopped.If the powder is "on" before the OSD function is executed, the power will exit to the main routine and if the power is "off", To "off".

When the alarm and OSD function by the organizer menu is finished, the original main routine is continued if the powder is "on" and the standby state is returned to the initial state if the powder is "off".

On the other hand, the position movement of the cursor (CURSOR) during the execution of the ELECTRONIC MEMO menu of the present invention may be used by a program that moves the cursor when inputting normal character data, and the key for specifying the movement of the cursor depends on the intention of the manufacturer. It is enough to select and set an arbitrary function key of each function key of the remote controller.

In addition, the character data displayed on the screen can be deleted by pressing the Clear key. At this time, the characters on the OSD screen and the data stored in the NV RAM are deleted.

The insertion of characters and the data for characters are configured to be inserted and input by a conventional method and an arbitrary key selection.

In addition, the alarm (ALARM) of the present invention can be displayed by using a voice signal using a speaker or by blinking a part of the screen.

As described above, the present invention inputs various messages required by using the NV RAM of the image device and sets the time, and when the set time comes, the message memorized with the alarm function is displayed on the OSD screen. You can easily know what to do.

In other words, the message entered at the set time is displayed on the OSD along with the alarm, so that the user can easily know the appointment time, the day of celebration, or the necessary memo, so that the video device can be used more conveniently and conveniently. It is possible to provide an electronic notebook, which is not cleared due to power failure.
