Abstract

PURPOSE:To improve convenience to use by neglecting a switch operation for projecting a special picture at the time of a picture recording by a VTR. CONSTITUTION:At the time of monitoring a picture recording, when a video signal recorded in the VTR 40 is projected on a sub-screen and the switch for projecting the special picture such as a still picture or a stroboscopic picture on the sub-screen is operated, a system control 90 discriminates whether the VTR 40 is recording the picture or not. According to this discrimination result, when the VTR 40 is recording the picture, the switch operation for projecting the special picture is neglected. Namely, when the switch for the still picture or the stroboscopic picture is depressed, the sub-screen is brought into the still picture or the stroboscopic picture if the VTR 40 is not recording the picture, however, when the VTR 40 is recording the picture, the switch operation is neglected, the contents of the picture recording are projected on the sub-screen and 'during picture recording' is warned. Thereby, a user does not misunderstand by convenience to use is improved.

[Detailed description of the invention] The explanation will be given in the following order.

Effect G Example Effect of H invention 8. Industrial application fields The present invention relates to a VTR-integrated television receiver.

B. Summary of the Invention The present invention provides a VTR-integrated television receiver having a picture-in-picture function that, when monitoring recording,
The ease of use is improved by performing predetermined control processing.

C. Conventional technology In general, a VTR with a channel selection channel circuit and a television receiver are separate units, and these are used in combination, so it is possible to record the current program while watching it, or to record it while watching it. You can record the other program while watching the program.

In this case, since the VTR and the television receiver are separate, there is no confusion between the channel selection section on the VTR and the channel selection section on the television receiver. There is no confusion between selecting a channel and selecting a channel to be recorded on a VTR.

In other words, there is no problem with the operability of image reception and recording.

Also, even if you integrate a deck-type VTR that does not have a tuner circuit with a TV receiver, there will only be one tuner circuit, so you can record the channel you are currently watching by simply pressing the record switch. However, there are no particular problems with operability.

However, the deck type V was used in TV receivers that were designed to display a small sub-screen within the main screen, so-called picture-in-picture.
If the TR is integrated, it will have a tuner circuit for the main screen and a tuner circuit for the sub screen.
This causes problems in operability during recording.

That is, if the system is configured so that the channel on the main screen is always recorded when the recording switch is pressed, it will be easier to use, but it will not be possible to record the other program (sub-screen).

Therefore, if you configure the channel so that it records the channel on the sub-screen when you press the recording switch, you will be able to record the other program, but the sub-screen will sometimes be displayed and sometimes not. Therefore, when the screen is not displayed (this depends on the user's selection), it becomes a problem to check the channel and program content.

Furthermore, it is conceivable to provide a switch that selects the main screen channel and the sub-screen channel, and configure the screen to record the channel selected by this switch, but if the sub-screen is not displayed, , the same problem occurs, and the correspondence between the channels recorded by switching the switch and the channels on the main screen and the channels on the sub-screen is reversed, and
Since the VTR and TV receiver are integrated and all operation switches are located on the front of the cabinet,
Easy to make operational errors.

Also, when only the main screen is being displayed, the main screen channel may be recorded, and when the sub screen is also being displayed, the sub screen channel may be recorded. Operation becomes complicated

The TR (40) receives an operation mode control signal MODII! from the system controller (90). is supplied, and during playback, a color video signal v4 and an audio signal S4 are extracted.

Further, (81) to (84) indicate switch circuits, and these switch circuits (81) to (84) have contacts A to C, and signals v1 to Vn and St to S4 are applied to these contacts A to C as shown in the figure. At the same time, a control signal sw is supplied from the system controller (90), and the switch circuit (
81) and (82), any one of the video signals V1 to V4, Vi, VJ(1-1, 3, 4
, j-2 to j-4) are taken out, respectively, and the switch circuit (
83) and (84), signals 31 and Sj of the audio signals 81 to S4 are extracted, respectively.

Further, (51) and (54) indicate Y/C processing circuits, and these processing circuits (51) and (54) receive signals Vi and V from switch circuits (81) and (82).
j is supplied and made into three primary color signals Ci and CJ, and the signal Ci
is supplied to the synthesis circuit (52), and the signal CJ is supplied to the synthesis circuit (52) through the reduction circuit (55).

In this case, the reduction circuit (55) includes, for example, an A/D converter, a memory, a D/A converter, etc., and converts the signal Cj
A control signal CTRL for controlling still playback, strobe playback, etc. is also supplied from the system controller (90). The synthesis circuit (52) also receives a control signal E from the system controller (90).
Controlled by the NSB, when in a mode in which the sub-screen is not displayed, the input signal CI is output as is, and in a mode in which the sub-screen is displayed, the signal Cj is synthesized with the signal Ct and output.

The output signal of this synthesis circuit (52) is supplied to the color picture tube (53), and the switch circuit (83) is supplied to the color picture tube (53).
) from the speaker (5) through the amplifier (58).
7).

Further, signals Vj and Sj from the switch circuits (82) and (84) are supplied to the VTR (40) as recording signals.

Further, the ROM of the microcomputer constituting the system controller (90) is provided with a routine (100) shown in the flowchart shown in FIG. 4, for example.

In such a configuration, when the signal BNSB prohibits the synthesis of the signal Cj in the synthesis circuit (52), the switching circuit (81) and (83) are switched. , (83) allows you to view images and audio from any signals vt and st on the main screen, and also allows you to view the images and sounds from the signals V1+81
At this time, any channel can be viewed using the signal CHNI.

Also, signal II! When the synthesis of the signal Cj in the synthesis circuit (52) is permitted by the NSB, display of the sub-screen is permitted, and the switch circuits (82), (84
), and according to the switching of the switch circuit (82), an image according to an arbitrary signal Vj is displayed on the sub-screen, and at the time of signal 2, an arbitrary channel can be displayed according to signal CHN2.

Therefore, in this case, the switch circuits (81) to (
84), the sub-screen according to Table 2 is displayed within the main screen according to Table 1.

Then, with the switch circuits (81) to (84) connected to contact A or B, the VTR is
When (40) is set to the recording mode, the routine (100') of the flowchart shown in FIG. 4 is executed to perform recording.

That is, now, for example, switch circuits (81) to (84)
is connected to contacts A to A, as shown in ■ in Fig. 5A,
It is assumed that only the main two sides are being projected, and that the image of the 14th channel is being projected on this main screen. Alternatively, it is assumed that not only the main screen but also a sub-screen is displayed, and the image of the 21st channel is displayed on this sub-screen, as shown in 1 of FIG.

Then, when in this state, switch (9A)
When the recording switch of ~(9N) is pressed, the processing of the CPU of the system controller (90) starts from step (101) of the routine (100) and then moves to step (102).
In this step (102), the signal CIIN
The value (data) of I is copied to signal CHN2 regardless of the previous value of signal ClN2.

In this case, the signal CHN2 also has a value for selecting the 14th channel, and the 14th channel is also selected in the chainer circuit (21).

The process then proceeds to step (103), and in this step (103) the switch circuit (82
) and (84) have the same contact position as switches (81) and (83) regardless of the previous contact position. In this case, the switch circuit (82), (8
4) is connected to contacts A and A.

Therefore, by steps (102) and (103), the signal Vj is output from the switch circuits (82) and (84).

Sj is the signal V2.32 of the channel selected by the tuner circuit (21), and the tuner circuit B (
11), the same signals v2 and s2 as the signal V1.31 of the selected channel are output. In this case, it is the switch circuit (82).

(84) to the first channel selected in tuner episode II (21)
A 4-channel signal V 2 +32 is taken out.

Therefore, if displaying the sub screen is permitted,
As shown in (■) in FIG. 5B, the image of the 14th channel is also displayed on the sub-screen.

Next, the process proceeds to step (104), and in this step (104), the signal MODB is sent to the VTR (40).
is considered to be recording mode. Therefore, VTR (40)
On the other hand, the signals V2 and S2 (-Vj.

In other words, the oEq of the channel that was being displayed on the main screen before the recording switch was pressed, in this case the 14th channel, is started.

Then, the process proceeds to step (105), and in this step (105), as shown in (■) in FIG. 5A and B,
The sub-screen is displayed by the signal ENSB regardless of whether the sub-screen has been displayed before. in this case,
Channel (ll) signal V2 displayed on this sub screen
(-Vj) is equal to the signal V2 (=Vj) of the channel supplied to the VTR (40), that is, the channel being recorded in the VTR (40), in this case the 14th channel, is the sub-screen. It will be shown on the screen.

Subsequently, the process proceeds to step (106), in which the process waits for, for example, 5 seconds, and then proceeds to step (10'?).
7), it is checked whether or not the sub-screen was displayed before this routine (100) was executed;
When the sub-screen is not displayed, the process proceeds from step (107) to step (108), and the signal [! After the display of the sub-screen is prohibited by the NSB, the process proceeds to step (109), and when the sub-screen is displayed, the process proceeds from step (107) to step (109), as shown in ■ in FIG. 5B. The sub-screen remains displayed, and this routine (100) is ended at step (109).

Thus, according to this television receiver, the switch (9A
) ~ (9N) When you press the recording switch, CllN
2- As CHNI, make the signal Vj match the signal Vi displayed on the main screen at that time, and
j is recorded on the VTR (40), so when you press the record switch, the image displayed on the main screen at that time will always be recorded, ensuring that the desired channel is recorded. And it's easy to record.

In addition, the main screen and sub-screen can be set independently, so you can record the other program while watching the main program.
You can also check the recorded content on the sub-screen.

Furthermore, when the signal Vj is made to match the signal Vt displayed on the main screen, it is not determined whether it is Vj - Vi, that is, steps (102) and (103) are performed regardless of the previous state. Therefore, the routine (100) is simple.

Moreover, when the recording switch is pressed, the sub-screen will be displayed regardless of whether it was displayed previously, and the sub-screen will become the channel being recorded on the VTR (40). You can confirm the channel that you want to record, and this also allows you to record reliably.

D Problems to be Solved by the Invention By the way, when the picture-in-picture function is provided as described above, the reduction circuit (55) as described above
has a memory, so the signal CJ from this memory
Although reading is performed normally and continuously, if writing of the original signal Cj is stopped, the sub-screen can be made into a still screen. Alternatively, the original signal Cj may be written to the memory intermittently every predetermined field period, for example,
The sub-screen can be a so-called strobe screen.

However, as mentioned above, the TV receiver is VTR (4
0), and when recording, the recording signal V
j is enabled to be monitored for recording on a secondary screen, and when a special screen such as a still screen or strobe screen is executed on that recording monitor screen, the user can see that the recorded image is switched to the main screen signal vl. There is a possibility that you may misunderstand that the still screen was recorded continuously, and it is undesirable to stop recording in a hurry.

This invention attempts to solve these problems.

E. Means for Solving the Problems This invention projects the video signals recorded in the VT and R on the sub-screen during recording monitoring, and displays a special screen such as a still screen or a strobe screen on the sub-screen. When the switch for displaying the image is operated, it is determined whether or not the VTR is recording, and based on the result of this determination, when the VTR is recording, the switch operation for displaying the special screen is ignored. This is a TV receiver with an integrated VTR.

F Effect Improved ease of use.

G. The hardware of the embodiment is configured as shown in FIG. 1 and as described above, and the ROM of the microcomputer configuring the system controller (90) contains
In addition to routines (110) and (120) shown in FIGS. 2 and 3, for example, routines (110) and (120) are provided.

Then, when one of the switches (9A) to (9N) that makes the sub screen the still screen is pressed, the system controller (
90) CPU processing starts from step (111) of routine (110) and proceeds to step (112). In step (112), it is determined whether or not the VTR (4G) is recording, and recording is started. If it is not inside, the process proceeds to step (113), and this step (
113), the reduction circuit (55) is activated by the signal CTRL.
is controlled and its output signal CJ is used as a signal for both sides of the stay, and then in step (114) this routine (1
10).

Further, in step (112), if the VTR (40) is recording, the process proceeds to step (115), and the signal BNSH causes the sub screen to be displayed regardless of whether or not the sub screen is displayed in step (115). The screen is displayed, and step (116) causes this routine (110
).

Therefore, according to this routine (110), when the switch to set the still screen is pressed, if the VTR (40) is not recording, the sub screen is set as the still screen.
If the VTR (40) is recording, the recorded content is displayed on the sub-screen and a warning is given that ``recording'' is in progress.

Furthermore, if one of the switches (9A) to (9N) that makes the sub screen a strobe screen is pressed, the system controller (
90) CPU processing starts from step (121) of routine (120) and proceeds to step (122). In this step (122), it is determined whether or not the VTR (40) is recording, and the recording is started. If it is not inside, the process proceeds to step (123), and this step (
123), the reduction circuit (55) is activated by the signal CTRL.
is controlled and its output signal C' is used as a strobe screen signal, and then in step (124) this routine (1
20).

Further, in step (122), if the VTR (40) is recording, the process proceeds to step (125), and the signal BNSB is used to display the sub screen regardless of whether or not the sub screen is displayed in step (125). The screen is displayed, and step (126) causes this routine (120
).

Therefore, according to this routine (120), when the switch to set the strobe screen is pressed and the VTR (40) is not recording, the sub-screen is set as the strobe screen.
If the VTR (40) is recording, the recorded content is displayed on the sub-screen to warn that it is "recording".

Effects of the Invention According to this invention, when the switch for setting the still screen or strobe screen is pressed, the VTR (40
) is not recording, the sub screen will be used as a special screen such as the still screen or strobe screen, but if the VTR (40) is recording, the switch operation will be ignored and the recorded content will not be displayed on the sub screen. Since the user is warned that ``recording is in progress'', the user does not misunderstand the situation and improves ease of use.

Claims (1)

[Claims] In a television receiver that has a picture-in-picture function of displaying a reduced sub-screen within the main screen and is also integrated with a VTR, when recording is monitored, the video is recorded on the VTR. When a switch for displaying a video signal on the sub-screen and displaying a special screen such as a still screen or a strobe screen on the sub-screen is operated, it is determined whether or not the VTR is recording, and this determination is made. As a result, when the VTR is recording, a switch operation for displaying the special screen is ignored.
