The data 13 is inserted into a television signal and broadcast (as a television character multiplex broadcast program). By continuously receiving a predetermined number of program broadcast schedule information data 13 thus broadcast, it is possible to acquire the program broadcast schedule for one week of the currently selected channel (broadcasting station). Then, the control means 1 judges from the code data 25 of the program broadcast schedule information data 13 whether or not the data input from the VBI decoder 3 is the program broadcast schedule data, and if it is the program broadcast schedule data. , Writing to the storage means 4. The control means 1 repeats this operation for all channels (broadcasting stations) while the VBI data, that is, the data for which program broadcasting is scheduled continues (while being broadcast). Incidentally, the operation of fetching the program broadcast schedule data (writing operation to the storage means 4) is always continuously performed, and after the operation of fetching the program broadcast schedule data is completed (for all channels).
Rewrites only the changed program broadcast schedule data. Of course, it is also possible to overwrite all of the fetched program broadcast schedule data in the storage means 4 every time regardless of whether the data is changed or not.

Next, in the state where the above-mentioned operation is continuously performed (normal state), the storage means 4 stores
The operation of the timer reservation device according to the present invention when the program timer reservation operation is performed when the latest program broadcast schedule data for one week is stored for all channels (broadcasting stations) will be described.

FIG. 3 is a flow chart showing an operation example of the timer reservation device of the present invention.

FIG. 4 is a view showing a display example of the warning message displayed on the display means 5.

The display means 5 is, for example, as shown in FIG. 4A, the program reservation number display section 42, the day of the week display section 43, and the day of the week displayed on the day of the week display section 43 is the next week (second week). Second week display section 48 that displays the day of the week, reservation start time display section 44 that displays the reservation start time, reservation end time display section 45 that displays the reservation end time, and channel number display that displays the channel number. It comprises a section 46 and a tape speed display section 47 for displaying the tape speed (triple or standard).

In the embodiment of the present invention, the program reservation number display section 42 has six reservation memories, and when the reservation program data is registered in the reservation memory,
The reserved memory number is displayed, and the day of the week display section 43 displays the day of the week based on the reserved program data when a program is reserved and the current day of the week when the program is reserved. The eye display section 48 is the day of the week display section 43.
When the day displayed in is indicating the day of the next week (second week), the tape speed display section 47 displays the corresponding tape speed (triple or standard). It is supposed to be displayed.

The reservation start time display section 44 displays the reservation start time based on the reserved program data at the time of program reservation.
The current time is displayed except when the program is reserved, and the reservation end time display section 45 displays the reservation end time based on the reserved program data when the program is reserved. The channel number display section 46 does not display the reserved channel number based on the reserved program data when the program is reserved, and displays the predetermined channel number when the program is reserved.

Furthermore, the reservation start time display section 44, the reservation end time display section 45, and the channel number display section 46 display a warning message under the control of the control unit 1 when a program is reserved.

The operation of the timer reservation device according to the present invention when the program timer reservation operation is performed will be described below with reference to FIG.

First, the control means 1 judges whether or not the reserved program data 14 input from the reserved program input means 6 is the G code mixed data (step s1). If it is not the G code mixed data, The broadcast day (date), reservation start time, reservation end time, channel number, tape speed, and program genre (information such as sports, movies, dramas, news, and variety) of the reserved program.
Is input (step s2). If the reserved program data 14 is G code mixed data, the input process of the day (date) on which the program reserved by the G code is broadcast, the reservation start time, the reservation end time, and the channel number (step s3), Also, the tape speed and the program genre are input (step s12).

When the input of the reserved program data 14 is completed,
For the current day (date), the day of the week on which the program reserved by the input reserved program data 14 is broadcast (date)
Is checked for the next week (the date after 7 days) (step s4), and if it is the next week (the date after 7 days), the storage means 4 stores only the program broadcast schedule data for one week. Since it is not stored, for example, the display means 5
A message 1 as shown in FIG. 4B, that is, a message notifying the user that there is no data to be compared is displayed (step s7), and the reserved program data 1 is displayed.
If the user decides not to register (re-set) after waiting for the user to decide whether to register 4 (whether to ignore the message contents) (step s9), Returning to the step s1, resetting is performed, and when the user decides to register (do not reset), registration setting of the reserved program data 14 is performed (step s10), and program timer reservation operation is performed. To finish.

On the other hand, in step s4, the day (date) on which the program reserved by the reserved program data 14 is broadcasted
If it is not the next week (the date after 7 days), the reserved program data in the program broadcasting schedule data for all channels (broadcasting stations) for the latest one week stored in the storage means 4 The same data as 14 is searched (step s5), and the search data is confirmed (the existence of the same data is confirmed).
If so, it is judged that the set value of the program timer reservation of the user is correct, so the registration setting of the reserved program data 14 is performed (steps s6, 11), and the operation of the program timer reservation is completed. Further, when the presence of the same data as the reserved program data 14 is not confirmed, it is determined that the setting value of the program timer reservation of the user is incorrect, and, for example, in the display means 5, as shown in FIG. A message 2 as shown, that is, a message notifying the user that there is no program for which the user wants to set a timer is displayed (steps s6, 8), and whether or not to register the reserved program data 14 (the message If the user decides not to register (re-set) (step s9), the process returns to step s1 to re-set, If the user decides to register (not reset), the reserved program data 14 is registered and set (step s10), and the program timer reservation is made. To end the work. The reason why the user decides to register (do not reset) in step s9 is that, for example, before the broadcast of the program (reserved program data 14) for which the user is about to set a timer, a night broadcast or the like is performed. For example, when there is a program whose broadcast time may be extended, the user intentionally sets the reservation end time 27 with a delay of, for example, about one hour.

By the way, in general, the program to be set by the user is determined by a program broadcast schedule table (also simply referred to as a program table) such as newspapers and magazines, and timer reservation is made based on the information described in the program table. Is set. However, the programs published in the program guides of such newspapers and magazines are not absolute, and the contents of the programs may be changed due to the circumstances of the broadcasting station, such as the broadcasting of emergency special programs. In such cases, especially when the timer reservation setting of the program scheduled to be broadcast in a few days is set based on the information listed in the program guide of the magazine etc.,
A desired program is not recorded, and a program that one does not want to watch is recorded. This not only wastes tapes and electric bills, but also causes a situation in which a valuable program is missed.

Then, next, the timer program reservation setting has already been made and the reserved program data 14 stored in the reservation memory is stored.
The latest 1 stored in the storage means 4 on a regular basis.
A function to notify the user that the timer reservation setting has become invalid, when the program is changed due to the circumstances of the broadcasting station, compared with the program broadcasting schedule data for all channels (broadcasting stations) for the week A timer reservation device according to the present invention having the above will be described.

FIG. 5 is a flow chart showing a control procedure for notifying the user when the timer reservation setting becomes invalid after the timer reservation setting.

Now, when four of the six reserved memories of the timer reservation device according to the present invention are in use (reserved program data is written), the program is changed due to the circumstances of the broadcasting station. An example of the operation of the timer reservation device according to the present invention for notifying the user of the reserved program data, that is, the timer reservation setting being invalid, will be described with reference to the flowchart of FIG. .

When the timer reservation device has four timer reservation settings, the display of the display means 5 is as shown in FIG.
As shown in (1) of (d), the program reservation number display section 42 displays the number of the reservation memory in which the reserved program data is stored.

Then, the control means 1 of the timer reservation device
As described above, the channel selection means 2 is controlled to take in one week's worth of broadcast-scheduled program data from the VBI decoder 3 (step t1), and one week's worth of each channel number is recorded. The broadcast-scheduled program data (latest data) is compared with the broadcast-scheduled program data (old data) for one week for each channel number previously fetched from the VBI decoder 3 (step t2), and if there is no change, the above step is performed. Returning to t1, the process of taking in one week's worth of broadcast-scheduled program data for each channel number is repeated. If a change occurs in step t2, one week's worth of broadcast-scheduled program data for each channel number, which is stored in the storage unit 4 and is stored in the VBI decoder 3 last time, is the latest data that has been loaded from the VBI decoder 3 this time. The broadcast-scheduled program data for one week is rewritten for each channel number (step t3). At this time, only the data portion in which the changed program is stored may be rewritten.

Next, stored in the storage means 4,
Determination of whether or not there is a program responding to the reserved program data 14 stored in the reservation memory among the program broadcasting schedule data for all channels (broadcasting stations) for the latest one week,
In addition, whether or not the day of the week (date) on which the program reserved by the reserved program data 14 stored in the reservation memory is broadcast is the next week (the date after 7 days) with respect to the current day (date) Is determined for each reserved program data stored in each reserved memory (step) t5, and it is determined that there is a program responding to the reserved program data stored in the reserved memory, and the reservation If it is determined that the day of the week (date) on which the reserved program is broadcast in the reserved program data stored in the memory is not the next week (the date after 7 days), the process returns to step t1 and the channel numbers The process of fetching broadcast program data for one week each is repeated.

On the other hand, as a result of the judgment, when there is no program responding to the reserved program data stored in the reservation memory, it is judged that the program has been changed. As shown in (2), the number of the reserved memory that stores the reserved program data for which it is determined that the program has been changed (No. 3 in the embodiment of the present invention)
Is flashed slowly to notify the user that the program registered in the reserved memory number 3 has been changed, and thus the reserved program data registered in the reserved memory 3 is invalid (step t6). Further, with respect to the current day of the week (date), it is determined that the day of the week (date) on which the program reserved by the reserved program data 14 stored in the reserved memory is broadcast is the next week (the date after 7 days). In this case, for example, as shown in (3) of FIG. 4D, the number of the reserved memory in which the determined reserved program data is stored (No. 2 in the embodiment of the present invention) ) Is flashed, the program registered in the reserved memory number 2 by the user is broadcasted of the program reserved by the reserved program data stored in the reserved memory for the current day (date). It is notified that the day of the week (date) to be displayed is the next week (the date after 7 days) (step t6).

Then, after that, the process returns to the step t1, and the process of fetching the broadcast-scheduled program data for one week for each channel number is repeated.

When the user sets the timer reservation, the opening and ending images of the program to be watched are cut and the timer reservation is set, that is, the recording start time is several minutes, for reasons such as tape saving. There is a case where it is set with a delay and the recording end time is set a few minutes earlier, but as a countermeasure in that case, the programs for all the latest channels for one week (broadcasting stations) stored in the storage means 4 are stored. Reserved program data stored in the reserved memory in the broadcast schedule data (including the recording start time and recording end time)
When performing before the determination of whether there is a program that responds to
Regarding the collation of the recording start time and the recording end time, for example, the start time and the end time in the program broadcast schedule data stored in the storage means 4 may be determined with a range of ± several minutes. May be.

Further, in the embodiment of the invention described above, the case where the timer reservation device is used in the VTR has been described, but the present invention is not limited to this, and it is convenient if the timer reservation function is necessary or is present. It can be applied to all possible electronic devices.

[0048]

As described above, according to the present invention, when the user makes a timer reservation setting by mistake, it is detected and a message is output to the user to prompt the user to change the setting. Therefore, it is possible to prevent erroneous reservation settings.

Further, even if the program for which the reservation setting is made is changed for some reason after the timer reservation setting is made once, the change is detected and the user is notified. By re-setting (correcting) the timer reservation setting, it is possible to surely perform reserved recording for a target program.
