Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a 5K video tape recorder in which operations such as recording are prohibited during a specific time period according to the user's wishes.

The present invention relates to a video tape recorder in which operations such as recording are prohibited during a specific time period according to the wishes of the user. By recording the video signal, 5K is used to prevent misunderstandings such as malfunctions regarding the prohibition of operations.

[Conventional technology]

Although audiovisual equipment such as televisions and video tape recorders are extremely effective when used for education, many television programs that are undesirable for the mental health of young people are broadcast in so-called late-night broadcasts. On the other hand, if parents or guardians are always near the television set, it is easy to prohibit viewing of such programs. However, it is difficult to perform such K in reality. Furthermore, especially in video tape recorders, if so-called timer recording is performed, it is extremely easy to record programs without the parents' knowledge and view them when the parents are not present.

By the way, television receivers have a built-in memory and a timer device, and parents, etc. have to memorize the prohibited viewing times and channels in the memory.When the timer device reaches that time, a computer etc. can determine the status. A device has been proposed that prohibits viewing.

FIG. 4 shows a 70-chart of a computer for this purpose. It is assumed that setting data such as time zone and prohibited channels are stored in advance in the memory, and a well-known setting method is used as the setting method.

Incidentally, when the device is powered on, initial settings are first performed in step [l]. Subsequently, in step [2], the current time is detected from the timer device, and in step [3], the viewing prohibited time period is read from the memory. Then, in step [4], it is determined whether the current time is included in the prohibited time zone, and if it is not included, the normal operation mode is set in step [5]. Further, in step [6], it is determined whether or not a request to turn off the power of the device has been made, and if there is a request to turn off the power, the device is turned off after being controlled to turn off in step [7]. Further, if there is no request for turning off at step [6], the process returns to step [2].

Furthermore, if the current time is included in the prohibited time zone in step [4], it is determined in step [10] whether or not a prohibited channel is set. If no prohibited channels are set here, use is completely prohibited. If no prohibited channels have been set, a "prohibited" message is displayed on the screen of the receiver in step [11], and after a predetermined period of time has elapsed in step [12], step [13] ], the device is turned off.

If a prohibited channel is set in step [10], the receiving channel is detected from the receiving tuner section in step (21), and the prohibited channel is read from the memory in step (22). Then, in step [23], it is determined whether the receiving channel is a prohibited channel or not, and if it is not a prohibited channel, the process proceeds to step [5]. Further, if the channel is prohibited in step [C], a message "Channel prohibited" is displayed on the screen of the receiver in step [S]. Furthermore, in step [section] it is determined whether or not the reception channel has been changed, and if it has been changed, the process returns to step [21]. Also step [5]
If no change is made in step [26], the elapsed time is determined in step [26], and when the predetermined time has elapsed, step [26] is performed.
27], the off control is performed and the device is turned off.

Therefore, according to this device, even if you try to watch TV during the prohibited viewing time set by your parents, etc., a message such as "Do not use" will be displayed on the receiver screen, and programs that are considered harmful to young people will be displayed. It is possible to prohibit viewing such as.

However, in the case of video tape recorders, even if the above-mentioned configuration is applied as is, not only will it not work effectively, but
There is a risk that it may be misunderstood as a malfunction. That is, in general, recording with a video tape recorder is often done by so-called timer recording, and in that case, it is unfortunate that the user is nearby during recording. r
It is meaningless to display a message such as "No general tr. insect drawings allowed." In addition, when rewinding and playing back the tape after recording has finished, it is not possible to determine whether the fact that no recording was made on the tape was due to recording being prohibited or because the device was malfunctioning. There is an extremely high possibility that it will be misunderstood.

On the other hand, when setting timer recording, it is possible to judge the set time and the prohibited time period and display a message such as "Recording prohibited", but if the prohibited time period etc. In some cases, recording may be performed after the settings have been made, and in that case, something that was supposed to be recorded may be prohibited, which may cause more inconvenience.

[The problem that the invention attempts to solve]

Conventional devices were constructed as described above. For this reason, when applied to a video tape recorder, not only will it not work effectively, but it may even be misunderstood as a malfunction.
There were problems such as:

[Means for solving problems]

The present invention has a time zone storage memory (161) and a timer device αη.
and detects that the time from the timer device is included in the time zone stored in the memory (comparison unit 08
3) L. In a video tape recorder whose operation is limited (control unit αI) during this detection period, a predetermined video signal generation source α stage is provided, and the operation is set to recording mode during the detection period. When a predetermined video signal from the above source is recorded on the tape (6) (switch (2)
)) is a video tape recorder.

[Effect]

According to this device, a video signal indicating "recording prohibited" etc. is recorded on the tape recorded during the prohibited time period.
When this tape is played back, this video is displayed, clearly indicating that recording is prohibited. This also eliminates the risk of being misunderstood as a malfunction.

〔Example〕

In FIG. 1, a received signal from a tuner (1) is taken out through a changeover switch (2), and this received signal passes through a recording circuit (3) and a recording/reproduction changeover switch (4) to a rotary head (5) where it is transferred to a tape ( 6) Recorded above. Also, the playback signal played from the tape (6) by the rotary head (5) is taken out through the recording/playback switch (4) and the playback circuit (7), and converted into a signal of an arbitrary channel by the RF circuit (8). output terminal (not shown) to a television receiver (not shown).
9).

Furthermore, a system control circuit section for controlling a recording circuit (3), a recording/reproduction switch (4), a reproduction circuit (7), etc. is provided, and this system control circuit section is controlled by a microcomputer aυ. is setting key a3. It is controlled by operation keys 03 and the like, and the contents of this control are displayed on the display section α. The setting key αa, the operation key αj1 and the display part α are configured as shown in FIG. “End”, channel key “CH”
, clear key "CL" and registration key "1" are provided,
The operation keys (13) are provided with keys such as ``1 record'', ``playback'', 1 rewind'', ``fast forward'', 1 stop'', 1 pause'', etc., as in a normal video tape recorder, and the display section I Each is provided with a two-digit channel "CH" display section consisting of a so-called "day" display section, a four-digit time display section, etc. The pen is a cassette insertion slot.

In the above configuration, normal recording playback is performed using operation key Q3)
This is done in a conventionally known manner by manipulating the . In addition, when performing so-called timer recording, for example, set the recording start time by pressing the start key of the setting key C13 and operating the numeric keypad, then set the channel by operating the numeric keypad while holding down the channel key, and finally set the recording start time. Press and hold the end key while using the numeric keys to set the recording end time.

In addition, if you make a mistake in the settings or after timer recording is completed and the settings are no longer necessary, you can cancel the settings with the clear key. As a result, the recording that has been set (J-IIIM 紘葡) Iφ-1 is started as soon as possible, and then it can be ended at the set recording end time. can. Further, the current time, channel, etc. and the set time, channel, etc. are displayed on the display section (14).

In this device, a predetermined video signal generation source a9 is further provided, and this generated video signal is transmitted to the changeover switch (
2). The video signal generated here indicates that so-called recording is prohibited.
A text message such as "Recording prohibited" or a simple message
This may be announced by means of a picture or the like.

In addition, a memory αe and a timer device (17) are provided in connection with the computer αυ, and data from these are compared in a comparison section H, and the comparison output is supplied to a control section I to control the system control circuit 0Q, etc. be done. That is, the following program is installed on the computer Qυ.

In FIG. 3, A is a flowchart of the main routine, in which when the power of the device is turned on, the first step [
31], initial settings are performed. Next step (32)
Main operations such as other system controls are performed in .

Furthermore, in step [33] it is determined whether or not a recording request has been made, and if so, various flags indicating the operating status are reset in step [a], and in step [35]
7 lags for recording are set. And step [33
] and step [36]
You can proceed to

At this step [%], it is determined whether or not the recording flag is set, and if it is set, step [3]
7], the recording subroutine is executed, and step [Audience] is executed.
When it is not set, you can proceed to the step [feather].

That is, B is a flowchart of the recording subroutine, and when this subroutine is called, the current time of the timer device αη is first detected in step [71], and the recording prohibited time period in the memory is detected in step [72]. Read out. To set the recording prohibited time period to the memory ae, for example, press the registration key of the setting key aa and enter a desired password using the numeric keypad to enter the setting mode, and then record in the same way as setting timer recording. Set the start time, channel, and end time of the prohibited time period. Furthermore, after setting, press the Kama key again to cancel the setting mode.

Then, in step [73], it is determined whether or not the above-mentioned current time is included in the recording prohibited time zone, and if it is not included, in step [74], switch (2) is set to tuner (1).
) side, and in step [75], the recording mode is set and the process returns to the main routine.

If the channel is included in step [73], it is determined in step [76] whether or not a recording prohibited channel is set. If set, the receive channel of tuner (1) is detected in step [77], the recording prohibited channel of Mesori αe is read out in step [78], and if they match in step [79], the reception channel of tuner (1) is detected. It is determined whether or not there is. If they do not match, the process proceeds to step (74) K and normal recording is performed.

Furthermore, if there is no set channel in step [76] (
If all channels are prohibited) and the channels match in step [79], the process advances to step [add]. In this step, the switch (2) switches to the source (
It is switched to the 1!9 side, and the elapsed time is determined in step [81]. For example, if it is within 30 seconds, the recording mode is set in step [82] and the process returns to the main routine.
When the time is longer than 2 seconds, the process is put into stop mode at step [Ku] and returned to the main routine.

Note that step [81] is composed of, for example, a kind of counter, and a count is performed every time this step [81] is passed, and the product of this count value and the time it takes to go around the main routine and subroutines is 30 seconds. When the count value exceeds this value, it is determined that 30 seconds have passed. This counter is reset at the same time as various flags such as step are reset.

The subroutine is thus executed and the process returns to the main routine. Furthermore, in the main routine, it is determined whether or not a request to stop is made in step [镊], and if it is made, various flags etc. are reset in step [39], and in step [40] it is determined that the stop request is not made. At the same time, the process proceeds to step [41]. In this step [41], it is determined whether or not the stop flag is set, and if it is set, the stop mode is set in step [42], and if it is not set in step [41], then step [4] You can proceed to

Furthermore, it is determined whether a request to power off the device has been made in step [invitation], and if there is no request, step [invitation]
be returned to. Also, if there is a request to turn off, step [
After the off control is performed in step 4], the device is turned off.

Therefore, in this device, when a request for recording is made by pressing the operation key or by setting a timer recording within the recording prohibited time period, this is determined in the subroutine of step [37], and the switch (2) is changed to cause the recording to occur. After the video signal from source a51 is recorded on tape (6) for 30 seconds,
The device goes into stop mode. Therefore, when this tape is later played back, this video will be displayed, making it clear that recording was prohibited, and there is no risk of this being misunderstood as a malfunction.

Even if the recording mode was started before the prohibited time period, according to the above configuration, the above operation will occur as soon as the prohibited time period begins, and the recording time will not be set until after the prohibited time period. In this case, when the prohibited time period ends, normal operation will resume and recording will resume.
At 0 seconds, the above-mentioned "recording prohibited" video line is recorded.

In addition, in the above-described configuration, the operating state remains unchanged regardless of the order in which the timer time is set and the high image prohibition time period is set, so that no inconvenience occurs due to a change in the operating state.

〔Effect of the invention〕

According to the present invention, a video signal indicating "recording prohibited" is recorded on the tape recorded during the prohibited time period, and when this tape is played back, this video is displayed and recording is prohibited. It is possible to clearly indicate what is prohibited.

This also eliminates the risk of being misunderstood as a malfunction.5.
