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 8. Industrial application fields °　This invention relates to a VTR-integrated television receiver.

B. Summary of the Invention This invention improves ease of use in a VTR-integrated television receiver having a picture-in-picture function by performing predetermined display processing when the V'rR is switched from recording mode to stop mode. This is an improved version of .

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 watch the current program. You can record the other program while watching the program.

In this case, since the VTR and the television receiver are separate units, it is impossible to confuse the channel selection section of the VTR with the channel selection section of the television receiver.1. Therefore, there is no confusion between selecting a channel to be displayed on a television receiver 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 chainer circuit with a TV receiver, there is only one chainer 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, when a deck-type VTR is integrated into a TV receiver that is capable of so-called picture-in-picture, in which a smaller sub-screen can be displayed within the main screen, the main Since it has a Chener circuit for the screen and a Chener circuit for the sub-screen, a problem arises 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
(Literature: Japanese Patent Publication No. 11510/1983) V 'l' which eliminates the above problems.
An R-integrated television receiver is being considered.

First, an example of such a receiver will be explained using an fAt diagram.

In this case, the reduction circuit (55) includes, for example, an A/D converter, a memory, a D/A converter, etc., and outputs the signal C3.
This is for converting the signal into a signal for the sub-screen. Also,
The synthesis circuit (52) is controlled by the control signal BNSB from the system controller (90), and outputs the input signal CI as it is when the sub-screen is not displayed, and outputs the input signal Ct when the sub-screen is displayed. The signal c3 is synthesized and output.

Furthermore, (59) indicates a forming circuit, and this forming circuit (5

) from the speaker (5) through the amplifier (56).
7).

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

Further, the ROM of the micro combinator that constitutes the system controller (90) is provided with a routine (100) shown in the flowchart shown in FIG. 3, for example.

In such a configuration, when the signal HNSB prohibits the synthesis of the signal c3 in the synthesis circuit (52), Table 1 corresponds to the switching of the switch circuits (81) and (83), and the switch circuit By switching between (81) and (83), you can view images and audio based on arbitrary signals Vi and Si on the main screen, and the signal VLsS1
At this time, any channel can be viewed using the signal CQNI.

Furthermore, when the synthesis of the signal Cj in the synthesis circuit (52) is permitted by the signal ENSB, 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, the signal VIOD! By V
When the TR (40) is set to the recording mode, the routine (100) of the flowchart shown in FIG. 3 is executed to perform recording.

That is, now, for example, switch circuits (81) to (84)
is connected to contact A-A, as shown in ■ in Figure 4A,
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 a sub-screen is displayed, and the image of the 21st channel is displayed on this sub-screen, as shown in 1 of FIG. Note that when the sub-screen is displayed, a white rectangular frame is displayed around it.

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 CHNI
The value (data) of is copied to the signal CLLN2 regardless of the previous value of the signal CHN2.

In this case, the signal CHN2 also has a value that selects the 14th channel, and the chase 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
No. 4) Connected to contacts A and A.

Therefore, by steps (102) and (103), signals ■j are output from the switch circuits (82) and (84).

Sj is the signal V 2 T 32 of the channel selected by the Chener circuit (21), and the signal Vl of the channel selected by the Chener circuit (11)
, St. The same signal V2. S2 will be output.

In this case, it is the switch circuit (82).

The 14th channel selected from (84) by Chena circuit (21)
Channel signals V2 and St are taken out.

Therefore, if the display of the sub-ii- is permitted, the image of the 14th channel is also displayed on the sub-screen, as shown by ■ in FIG. 4B.

Next, the process proceeds to step (104), and this step (104) receives the input signal MODII! VTR (4
0) is set to recording mode. Therefore, VTR (4G
) d, the signal Vx s St (-Vj +
In other words, recording 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 FIGS. 4A and B, the signal 1! A sub screen is displayed by NSB. In this case, the signal V2 of the channel displayed on this sub-screen
(-Vj) is equal to the signal V2 (-Vi) of the channel being supplied to the VTR (40), i.e.
The channel recorded on the VTR (40), in this case the 14th channel, will be displayed on the sub-screen. Also, at this time, the frame around the sub-screen turns red to indicate that the signal Vj on the sub-screen is being recorded.

Next, the process proceeds to step (106), and after waiting for a time of 5 seconds, for example, in this step (106), the process 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), proceed to step (10B) and proceed to ■ in Figure 4A.
As shown in Figure 14, the process proceeds to step (109) after the display of the sub-screen is prohibited by the signal HNSB, and if the sub-screen is being displayed, the process proceeds from step (107) to step (109) and returns to v14, Figure B. As shown in (3), the sub-screen remains displayed, and this routine (100) is ended at step (109).

Thus, according to this television receiver, the switch (9A
) to (9N), when you press the recording switch, CHN2
= As CIINI, match the signal Vj with the signal Vi displayed on the main screen at that time, and write this signal v along with the name.
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 Vi displayed on the main screen, it is not determined whether it is v3-vt, 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 check 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, if the VTR (40) is a sufficiently small VTR such as an 8mm video, even if it is a TV receiver with an integrated VTR (4G), its size and The appearance is V'r
It has the same size and appearance as a general TV receiver that does not have a built-in R(40), and the front of the cabinet displays the channel, V'rR(40) operating mode, etc. There will be no space left.

Therefore, the channel, operating mode of the VTR (40), etc. are displayed by displaying characters or symbols indicating the channel, operating mode, etc. on the screen of the picture tube (53), as described above. is common.

However, if you do that, when you change the V'rR (40) from recording mode or playback mode to stop mode,
This will cause a problem with the display.

In other words, the signal v3 recorded by the VTR (40) is displayed on the sub screen, but when switching from recording mode to stop mode, "5TOP" is always displayed on the main screen regardless of whether there is a sub screen or not. If the characters or symbols are displayed, it may give the illusion that the main screen signal Vt has been recorded up until now, which is difficult for the user to understand and can easily lead to mistakes.

In addition, V'rR (40) (7) The playback signal v4 can be displayed on both the main screen and the sub screen, but when the stop mode is set, the characters or symbols "5TOP" are always displayed on the main screen. , it is still difficult for users to understand.

This invention attempts to eliminate these problems.

E Means for Solving Problems This invention has a picture-in-picture function that displays a reduced sub-screen within the main screen, and also has a V
In a television receiver with an integrated TR, when an operation is performed to put the VTR in stop mode while an image from the recording signal or playback signal of the VTR is being displayed on the sub-screen, the above-mentioned The VTR-integrated television receiver is configured to set the VTR in a stop mode and display characters or symbols on the sub-screen indicating that the VTR is in the stop mode.

F Effect Stop mode is properly displayed.

G. The hardware of the embodiment is configured as shown in FIG.
00), for example, the routine (110) shown in FIG.

Then, when the VTR (40) is playing, or by the routine (100), the VTR (4G)
When recording is in progress, switch (9^) ~
When the stop switch (9N) is pressed, the processing of the CPU of the system controller (90) starts from step (111) of the routine (110) and proceeds to step (112). 1'l0D
V'I'R (40) is set to stop mode by H, and then, in step (113), this routine (11G
) is executed, it is determined whether the mode of the VTR (4) was the recording mode or the playback mode.

If the recording mode is changed to the stop mode, the process proceeds to step (121), and this step (
In step 121), it is determined whether or not the sub-screen is being displayed, and if the sub-screen is being displayed, the process proceeds to step (122), and in this step (122), "5TOP" is displayed on the sub-screen by the signal otsp. A signal Cd for displaying characters is formed, and therefore "5T" is displayed on the sub-screen.
OP” will be displayed.Then, the process will proceed to step (
123) and ends this routine (110).

Further, if the sub screen is not displayed in step (121), the process proceeds to step (124), and in this step (124), the signal Cd for displaying the characters "5TOP" on the main screen is generated by the signal DISP. ,
However, at 9:00, the characters "5TOP" were displayed on the main screen.
This routine (110) is ended by step (125).

Further, if the playback mode is changed to the stop mode in step (113), the process is continued in step (13).
1), and in this step (131) it is determined whether or not the sub-screen is being displayed. If the sub-screen is being displayed, the process proceeds to step (132), and in this step (132), it is determined whether or not the sub-screen is being displayed. It is determined whether the signal v3 that was being displayed is the reproduced signal ■4 of V'l'R (40), and when Vj is V4, the process proceeds to step (133), and in this step (133) The characters "5TOP" are displayed on the sub screen by the signal Cd, and this routine (110
).

Also, when the sub screen is not displayed in step (131), and in step (132), VJ #
When V4, the process proceeds to step (135), and in this step (135), the characters "5TOP'" are displayed on the main screen by the signal Cd, and the process proceeds to step (136).
This routine (110) is ended.

Although not shown, when the VTR (40) is changed from fast forward mode, rewind mode, or stop mode, the characters "5TOP'" are displayed on the main screen.

Effects of the invention H Thus, according to the invention, when the recording signal Vj of the VTR (40) is displayed on the sub-screen, and when the VTR (4G
