Abstract

PURPOSE:To easily and surely perform picture recording, by displaying a video signal supplied to a VTR as a sub picture plane in spite of the display of the sub picture plane before then in the pause state of the picture recording. CONSTITUTION:When the VTR40 is set at a picture recording pause mode, the sub picture plane is displayed in spite of the display of the sub picture plane until then, and also, the image of the video signal Vj supplied to the VTR40 is displayed on the sub picture plane, and it is monitored. Thereby, it is possible to recognize the timing of the cancel of picture recording pause. Also, since the change of the channel of a tuner circuit 21 is prohibited only in picture recording and the change of the channel of the tuner circuit 21 is permitted in the picture recording pause, etc., it is possible to record a program on a different channel freely. In such a way, the picture recording can be performed surely and easily.

Description

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

A. Industrial application field B. Summary of the invention C Conventional technology D Problems that the invention attempts to solve E. Means to solve the problem (Figure 1) F. Effect G Example Effect of H invention A. Industrial application field The present invention relates to a VTR-integrated television receiver.

B. Summary of the Invention This invention enables recording to be easily and reliably performed in a VTR-integrated television receiver having a picture-in-picture function by performing predetermined control processing during a broadcast recording pause. This is how it was done.

C Conventional technology In general, a VTR with a tuner for channel selection and a television receiver are separate units, and these are used in combination, so it is possible to record a program while watching it, It is possible to record a subprogram while watching the main 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 is only one tuner circuit, so you can record the channel you are currently watching by simply pressing the record switch. , there are no particular problems with operability.
(No. 11510) However, when a deck-type VTR is integrated into a TV receiver that is capable of so-called picture-in-picture, in which a separate small sub-screen can be displayed within the main screen. Since it has a tuner circuit for both main and sub-screens and a tuner circuit for the sub-screen, this causes problems in operability during recording.

In other words, if you configure the system so that channels on both sides of the main screen are always recorded when the recording switch is pressed, it will be easy to use (although it will be easy to understand), but you will not be able to record the opposite 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, , a similar problem occurs. Moreover, when the switch is changed, the correspondence between the recorded channel, the main screen channel, and the sub-screen channel is reversed.In addition, the VTR and TV receiver are integrated, and all the operation switches are in the cabinet. Since it is located at the front, it is 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.

Therefore, a VTR-integrated television receiver is being considered that eliminates the above-mentioned problems.

First of all, such a reception @! Let's explain an example of the machine using Figure 1.

The audio signals S L *32 of the selected channels are respectively extracted in the tuner circuits (11) and (21).

Further, (31) and (32) indicate external input terminals, and external signal sources such as a video disc player (not shown) are connected to these terminals (31) and (32), and color video signals from the future are connected. v3 and audio signal S3

Further, (81) to (84) indicate switch circuits, and these switch circuits (81) to (84) have contacts A to C, and signals ■1 to V4. St to S4 are supplied in the combination shown in the figure, and a control signal SW is supplied from the system controller (90), and the switch circuit (
81), from (82), any signal V + + V J (i = 1.3) of the video signals v1 to v4
．． 4. j-2 to j-4) are respectively taken out, and the audio signals 81 to 84 are taken out from the switch circuits (83) and (84).
One of the signals S i + S J of S4 is respectively taken out.

Further, (51) and (54) indicate Y/C processing circuits, and these processing circuits (51) and (54) receive signals Vi and Vj from switch circuits (81) and (82).
are supplied as 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
This is for converting the signal into a signal for the sub-screen. Also,
The synthesis circuit (52) is controlled by the control signal ENSB from the system controller (90), and outputs the input signal Ci as it is when in a mode in which the sub-screen is not displayed, and outputs the input signal Ci as it is in the mode in which the sub-screen is displayed. The signal Cj is synthesized 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 (56).
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. 5, for example.

In such a configuration, when the signal Cj is synthesized in the synthesis circuit (52) by the signal ENSB, the signal Cj becomes MII in response to the switching of the switch times [8 (81) and (83). By switching the switch circuits (81) and (83), images and sounds based on arbitrary signals Vi and Si can be viewed on the main screen, as well as signals Vl.

When in Sl, any channel can be viewed using the signal CHNI.

Further, when the synthesis of the signal Cj in the synthesis circuit (52) is permitted by the signal EMSH, the projection of the sub-screen is permitted, and the switch circuits (82) and (84) become Table 2, and the switch circuit ( 82), an image based on an arbitrary signal Vj is displayed on the sub-screen, and at the time of signal 2, an arbitrary channel can be displayed using 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, V'
When the l''R (40) is set to the recording mode, the routine (100) of the flowchart shown in FIG. 5 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 1 of Fig. 6A,
It is assumed that only the main screen is displayed, and that the image of the 14th channel is also displayed on this main screen. Alternatively, it is assumed that not only the main screen but also the sub-screen is displayed, and the image of the 21st channel is displayed on this sub-screen, as shown in (■) in 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).
and in this step (102) the signal C)IN
The value (data) of I is copied to signal CHN2 regardless of the previous value of signal CHN2.

In this case, the signal CHN2 also has a value that selects the 14th channel, and the tuner circuit (21) also selects the 14th channel.

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).

S'' is the signal V2.32 of the channel selected by the tuner circuit (21), and is the signal V2.32 of the channel selected by the tuner circuit (21).
11) The signals Vl, Sl of the channel selected by
The same signals V2 and S2 will be output. In this case, it is the switch circuit (82).

The 14th station selected by the tuner circuit (21) from (84)
The signal V 2 + 32 of the channel is taken out.

Therefore, if displaying the sub screen is permitted,
As shown in (■) in FIG. 6B, 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 VTR (40)
is considered to be recording mode. Therefore, in the VTR (40), recording of the signals V2, S2 (-Vj, Sj) is started, that is, the channels that were being displayed on the main screen before the recording switch was pressed,
In this case, recording of the 14th channel is started.

Then, the process proceeds to step (105), and in this step (105), as shown in H of FIG. 6A and H,
The sub-screen is displayed by the signal ENSB regardless of whether the sub-screen has been displayed before. in this case,
Channel signal V2 (-
VJ) is equal to the channel signal V2 (=Vj) supplied to the VTR (40), that is, the VTR
The channel recorded in (40), in this case the 14th channel, will be displayed on the sub-screen.

Next, the process proceeds to step (106), and after waiting for a time of, for example, 5 seconds, proceeds to step (107).
), it is checked whether the sub-screen was displayed before this routine (100) was executed, and if the sub-screen was not displayed, the process proceeds to step (
107) to step (10B) and m in Figure 6A.
As shown in FIG. 6, after the display of the sub-screen is prohibited by the signal EMSH, the process proceeds to step (109), and if the sub-screen is being displayed, the process proceeds from step (107) to step (109), and the process proceeds to step (109). The sub-screen remains displayed as shown in (■) in B, and this routine (100) is ended in step (109).

Thus, according to this television receiver, the switch (9A
) to (9N), when you press the recording switch, CHN2
- As CHNI, make the signal VJ match the signal Vi displayed on the main screen at that time, and also make this signal Vj
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 selected and , you can easily 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.

Further, when the signal VJ is made to match the signal vi displayed on the main screen, step (102) is performed without determining whether or not VJ = Vi, i.e., regardless of the previous state. (103) by VJ wVi
Therefore, the routine (100) is simple.

Moreover, when the recording switch is pressed, the sub-screen is displayed regardless of whether it was displayed previously, and the sub-screen becomes the channel being recorded on the VTR (40). You can check the target channel, which also allows you to record reliably.

D. Problem to be solved by the invention By the way, the functions required for the recording pause of a VTR include stopping the running of the tape during unnecessary video signal periods such as commercials, and stopping the running of the tape during the recording pause. Even when switching from one channel to another, the connection can be made neatly.

However, when such a function is provided to the above-mentioned television receiver, the following problems arise.

In other words, if you are recording a subprogram while watching the main program on the main screen, and the subscreen is displayed, you can use the subscreen to know when to cancel the recording pause (restart recording). When the sub-screen is not displayed, it is not possible to know when to cancel the recording pause.

Also, when changing the recording channel during recording pause, copy the channel on the main screen to the channel on the sub-screen and configure to record this channel on the sub-screen, as in routine (100). cannot be recorded.

This invention attempts to eliminate these problems.

E. Means for Solving Problems This invention provides a method for displaying a video signal supplied to a VTR as a sub-screen during a recording pause, regardless of whether or not a sub-screen was previously displayed, and A VT that does not change the video signal supplied to the VTR when switching from recording pause mode to recording mode.
This is an R-integrated television receiver.

F Effect Provides functions necessary for recording pause.

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
00), for example, the routines shown in FIGS. 2 to 4 (
110) to (130) are provided.

Then, when recording is being performed on the VTR (40) by the routine (100), the switch (9A) (9N
) is pressed, the system controller (9) is pressed.
0) CPU processing starts from step (111) of routine (110) and proceeds to step (112), and in this step (112), the signal is The sub screen is projected by ENSB, and therefore, at that time, the VTR (
The video signal ■j recorded in step 40) is displayed as a sub-screen.

Subsequently, the process proceeds to step (113), and in this step (113), the VTR (40) is activated by the signal MODE.
is set to recording pause mode, and this routine (110) is ended at step (114).

Therefore, when this routine (110) is executed,
The VTR (40) enters the recording pause state, and at this time, the video signal ■j being supplied to the VTR (40) can be monitored on the sub-screen.

When the pause switch is pressed again while in this recording pause state, the processing of the CPU of the system controller (90) starts from step (121) of the routine (120), proceeds to step (122), and proceeds to step (122). 12
In step 2), it is checked whether the sub-screen was displayed before the sub-screen was displayed in step (112), that is, before the routine (110) was executed and the recording pause mode was entered, and the sub-screen was displayed. If it is being displayed, the process directly proceeds to steps (1, 24); if it is not being displayed, the process proceeds to step (123), and in this step (123), the display of the sub-screen is prohibited by the signal EMSH. The process then proceeds to step (124).

Then, in step (124), the recording pause of the VTR (40) is canceled by the signal MODE, and therefore the VTR (40) resumes recording. Also, the routine (
120) ends with step (125).

Therefore, when this routine (120) is executed,
The recording pause of V'rR (40) is released, and
The sub screen is returned to the state before entering the recording pause.

On the other hand, when the switch for changing the channel of the tuner circuit (21) among the switches (9A) to (9N) is operated, the processing of the CPU of the system controller (90) is performed using the routine (13).
0), start from step (131) and move to step (
132), and in this step (132) the VT
It is determined whether R (40) is recording, and if it is not recording, the process proceeds to step (134);
In this step (134'), a signal CHN2 is generated according to the previous switch operation, thereby changing the channel of the tuner circuit (21).

Then, the process proceeds to step (135) and ends this routine (130).

Further, when it is determined that recording is in progress in step (132), the process proceeds to step (133), and in this step (133) it is determined whether or not recording is in pause. The process proceeds to step (134), and if the recording pause is not in progress, the process proceeds to step (135).

Therefore, according to this routine (130), changing the channel of the tuner circuit (21) is prohibited only during recording, and except when recording is in progress, such as when recording or stopping.
21) Channel changes are permitted.

H Effects of the Invention Thus, according to the present invention, when the VTR (40) is put into the recording pause mode, the sub-screen is displayed by the routine (110) regardless of whether the sub-screen was displayed up to that time, and Since the image of the video signal vj supplied to the VTR (40) is displayed on this sub-screen and can be monitored, it is possible to know the timing when canceling the recording pause.

In addition, the routine (130) prohibits changing the channel of the tuner circuit (21) only during recording, and allows changing the channel of the tuner circuit (21) during recording pauses, so you can freely watch other programs. Can be recorded.

Furthermore, when the recording pause is canceled and recording is resumed, the subscreen is returned to the state before entering the recording pause by the routine (120), and the main screen channel is changed to the subscreen channel as in the routine (100). Since the video signal Vj of the channel of this sub-screen is not copied to the channel and supplied to the VTR (40), no new switch operation is required for the channel to be recorded or the sub-screen.
