Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a timer reservation device for performing program reservation recording at a designated date and time in a home video tape recorder (hereinafter, referred to as VTR) or the like. About.

(Prior Art) Generally, a VTR or the like has a program reservation function of reserving a broadcast program and recording the program at the reserved time. For example,
In VTR, reservation date, start time, end time, channel,
A reservation program including an operation mode and the like is set by key input means such as a remote controller, and when the current time reaches the set start time, recording is automatically started and ended.

Various setting methods are available for setting the reservation data, such as setting the displayed number up and down using the up / down keys, or directly setting the time and date using the numeric keypad. Exists. Of these, for the numeric keypad method, for example, 12: 3
4AM March 31 (March 31 at 12:34 am) 1 → 2 →
It is easy to understand and the number of key input is small because of the method of directly inputting numerical keys of 0 to 9 or AM / PM key sequentially like 3 → 4 → AM → 0 → 3 → 3 → 1 There is an advantage that quick setting can be performed.

By the way, if you want to partially modify the settings once,
For example, start time, date and time 3:30 PM March 31 at 11:30 AM11
In the case of correction on the 11th of the month, in the above numeric keypad method, the correction is usually performed by the setting procedures (1) to (10) shown in FIG. Indicates the position of a cursor (setting pointer), which is moved one by one by inputting a 0 to 9 key (including an AM / PM key) or operating a shift key. Initially, the cursor is located at the 10 o'clock digit, and if one key is entered at this cursor point in step (1), the procedure moves to step (2), at 13:30 PM on March 31, and the cursor moves to 1 Move to hour digit. When one key is input, the process proceeds to step (3) and the cursor moves to the tenth digit. Next, when the input of the 3 key or the shift key is performed, the procedure shifts to the procedure (4), and the cursor moves to one minute. When the 0 key or the shift key is input, the process proceeds to step (5), and the cursor moves to the AM / PM digit. Here, when the AM key is input, the process proceeds to step (6), and the cursor moves to the October digit. Next, when the 1 key is input, the process proceeds to step (7), and the cursor moves to the January digit. When the 1 key is pressed, the process proceeds to step (8) and the cursor moves to the 10th digit. Next, when the 1 key is input, the procedure shifts to the procedure (9) and the cursor moves to the 1st digit. Then, when the 1 key or the shift key is input, (1
0) and the cursor disappears, 11:30 AM November 11th,
Correction is completed.

By the way, in the setting procedure of FIG. 4, when one key is input in the procedure (1), an abnormal setting such as 13:30 PM is temporarily made in the procedure (2). (In this case, since AM and PM are used, it is normal to set the hour with a numerical value of 1 to 12.) Similarly, in (7), November and in (8), November
Temporarily abnormal settings such as the 31st. Even in this case, there is no problem if the data is corrected correctly to the end, but if the setting is completed in the state of (2), (7), or (8), the data is reserved as abnormal data. (Especially one
In the case of 3:30 PM or November 31, it may be assumed that this is a normal setting and make a reservation. ) To prevent this,
There is also a method of detecting an abnormal setting and prohibiting key input, but the correction procedure as described above stops halfway and cannot be corrected.

(Problems to be Solved by the Invention) As described above, in the conventional timer reservation device, when setting contents are corrected, an abnormal setting such as 16:00, March, or February 30 may sometimes occur. As a result, the contents of the correction are difficult to understand, and the reservation operation may end with an abnormal data. Also, if the input that becomes abnormal data is prohibited, 3
It is impossible to change from 11:00 to 13:00 from March to December.

The present invention eliminates the above-mentioned problems and provides a numeric keypad (including AM / PM
It is an object of the present invention to provide a timer reservation device which can be easily set only by inputting a key, and can be operated for a partial correction or the like by the same input method, thereby avoiding setting of abnormal data or the like.

[Means for Solving the Problems] The timer reservation device of the present invention has a data input key, and inputs reservation data consisting of time information or calendar information composed of a plurality of unit data. Input means for inputting in a predetermined order for each unit data by a key; storage means for storing the input reservation data; display means for displaying the input reservation data; and storage means for storing in the storage means. Means for correcting the reserved data, wherein when the unit data is corrected by operating the data input key, it is determined whether time information or calendar information including the input unit data is normal. Abnormal data determination means, and reserves unit data in the next and subsequent input order when the reserved data is determined to be abnormal by the abnormal data determination means. It constituted by comprising: a correction data generation means for generating correction data for correcting so that there are no inconsistent over data, and a correction means made of a changing means for changing the reservation data based on the corrected data.

(Operation) According to the above configuration, when the data of the reservation content input and set in the storage means temporarily becomes abnormal, this is detected,
Since the reservation setting content is corrected to consistent data by the correction data creating means, the abnormal data is not stored in the storage means as it is, and the abnormal data is not displayed on the display device as it is. Therefore, unlike the related art, there is no possibility that abnormal data is regarded as normal data and reserved. As a result, setting and correction of timer reservation can be performed smoothly without input errors.

(Examples) Hereinafter, the present invention will be described based on examples shown in the drawings.

FIG. 1 is a block diagram showing a timer reservation device according to one embodiment of the present invention.

In this figure, the timer reservation device 20 is
1, a control device 22, a storage device 23, an abnormal data determination device 24, a correction data creation device 25, and a display device 26. The input device 21 is a device for directly inputting the contents of the reservation setting such as numerical values such as 0 to 9, AM / PM, and the day of the week. Storage device
23 is a device for storing the contents of the reservation setting. Control device
Reference numeral 22 controls the transfer of data set by the input device 21 to the storage device 23, the setting of a cursor with respect to the 10 o'clock digit, the 1 o'clock digit, and the like of the storage device 23, and the control of shifting the cursor. Further, the abnormal data determination device 24 determines whether or not the result of the key input supplied to the storage device 23 by the input device 21 is normal. In other words, each time the digits supplied to the storage device 23, such as the 10 o'clock digit and the 1 o'clock digit, are set, it is determined whether the set data is abnormal data. Then, in the correction data creation device 25, when the abnormal data determination device 24 determines that the data is abnormal, the correction data generation device 25 outputs the correction data to the control device 22 so that no inconsistency occurs in each digit of the setting data. Alternatively, error display data is output. The display device 26 displays the reservation setting contents (including correction data and error display data) stored in the storage device 23.

FIG. 2 shows a display example of the timer reservation setting contents on the display device 26. The display screen 26A shows the reserved channel (CH), tape speed (SP, LP, etc.), start time (O
N), reservation time such as end time (OFF) and reservation date (DATE) are displayed. In the CH column, C stands for CATV, and in the DATE column, 3/31
/ 89 means March 31, 1989. SUN indicates Sunday.

Next, a method of setting the reservation data of the timer reservation device of FIG. 1 will be described.

FIG. 3 specifically shows a procedure for setting and correcting the reservation data.

FIG. 3A shows a procedure for newly setting a start time or an end time when the start time or the end time has not been set. The initial content is "-:-AM", that is, an unset state. Initially, the cursor is at the 10 o'clock digit. For example, by inputting the 1 key, 1 is set at the 10 o'clock digit, and the cursor is automatically shifted to the 1 o'clock digit. Similarly, for each digit, 2 → 3
By inputting each key in the order of → 4 → PM, “12:34 PM” is set. Although the case where the AM and PM keys are provided is described here, for example, one key is used instead of the AM key, two keys are used instead of the PM key, and one key or two keys are used. A method of setting AM or PM (or other keys) may be used.

FIG. 3 (b) shows a procedure for modifying the preset "10:30 AM" to "3:40 AM". Here, if the 0 key is input while the cursor is at the 10 o'clock digit, “00: 30A
M) is abnormal data.
Abnormal data is detected by the correction data creation device 25
Data of 1 is created as the hour digit, and the operation of changing the input data of the 10 hour digit to 0 (1:30 AM), which is consistent with "1:30 AM", is performed. Then, the 3 key is input at the 1 o'clock digit. After that, the 10 minute digit and the 1 minute digit are sequentially input by keys in the same manner. Here, when the 6 key is input for the 10-minute digit, the key input itself is regarded as abnormal data, error data such as "?" Is created and displayed, and the cursor is not shifted. Then, by inputting the 4 key to the 10-minute digit and the 0 key or shift key to the 1-minute digit, the correction is completed.

FIG. 3 (c) shows a procedure for correcting the preset date "3/31/89" to "4/30/89". here,
If you press the 4 key when the cursor is at the January digit, "4 /
31/89 ", the abnormal data is detected in the same manner as above, and the date correction data" 01 "is created by the correction data creation device 25, which is consistent with" 4/01/89 " Data. After that, 3 keys are input in order of 10 days, and 0 key is input in 1 day. Here, when 1 key is input in 1 day, the key input itself is abnormal. Error data such as "?" Is created and displayed as data, and the cursor is not shifted. Then, the correction is completed by inputting the 0 key or the shift key for the 1-day digit and the 8 and 9 keys (or the shift key) for the 10- and 1-year digits, respectively.

Fig. 3 (d) relates to the leap year, "2/19/8
9 (meaning February 19, 1989)
8 ”shows the procedure for correction. If you press the 2 key when the cursor is in the October digit, the abnormal data will be "2/29/89", so abnormal data will be detected in the same way as above,
The correction data creation device 25 creates the correction data “92” for the year, and sets the data to “2/29/92” without any contradiction. Then, when the 8 key is input to the 10-year digit, the abnormal data becomes “2/29/82”, so that the correction data “0” is created as the 1-year digit, and there is no contradiction of “2/29/80”. Data. After that, when the 8 key is input to the year digit, the correction is completed.

Thus, in the timer reservation device according to the present invention, 0
If there is an error in the data at the time of key input of ~ 9, etc., this is detected, and each time the correction data creating device creates consistent data, which is also lower than the cursor of the input which caused the abnormal data. Since the data of the lower cursor is corrected, smooth setting and correction can be performed without breaking the already input setting data. For example, "
In the setting of "Year", when setting the cursor order of October digit → January digit → 10th digit → 1st digit → 10 year digit → 1 year digit, for example, modify “February 19 89” If the 10th digit is corrected to 2 in the process, it becomes "February 29, 89" and abnormal data will be detected. This is detected and corrected data is created. It is also conceivable that “January 29, 89” may be used. However, at this time, since the cursor has already shifted to the one-day digit, the data of the one-day digit lower than the input ten-day digit cursor is set to 0 and “2”. In this case, the correction is made to “February 29, 92” with the data of the 20th year, 89 years ”or 10 years, 1 year digit data as 92.

Table 1 shows an example of creating correction data when the correction data creating apparatus inputs time data.

[Effects of the Invention] As described above, according to the present invention, even if abnormal data temporarily occurs during timer reservation setting, the abnormal data is detected and the correction data creating means always produces consistent data. In particular, when the direct input setting method using the numeric keypad is used, there is no possibility that the reservation is terminated without storing the abnormal data without storing the abnormal data. Therefore, the setting and correction of the timer reservation can be performed quickly (efficiently) by the same input method with less input errors.
