When the recording stop operation is performed by the operation unit 19, the process proceeds from step B14 to step B25 to notify the TV unit 1 of the recording stop operation, and at step B26, the channel of the tuner 3 displayed on the screen from the TV unit 1 is displayed. It waits for information and receives this information to synchronize tuner 16 to the channel of tuner 3. And step B
After the channel setting completion is notified to the TV section 1 by 27, the process proceeds to step B28 and the recording / reproducing section 17 is controlled to stop.

(III) Operation of the entire apparatus Then, the operation of the TV section 1 and the VTR section 2 causes the entire apparatus to operate as follows. (A) When both the TV unit 1 and the VTR unit 2 are in the power-on state, the tuner 3 or 1 whose power is first turned on
The channels of both tuners 3 and 16 are synchronized with reference to the channel of 6, and the input source of the TV section 1 is switched from the tuner 3 to the VTR section 2.

By this switching, thereafter, the tape reproduction output or the reception output of the VTR section 2 is C except when the VTR section 2 is recording.
The screen is displayed on RT10. (B) When playing back the VTR section 2, the VT of the TV section 1
By operating the R button 15, the VTR section 2 is controlled to reproduce and the display screen of the CRT 10 becomes the tape reproduction screen.

At this time, the VTR section 2 is pressed by the VTR button 15.
Can be selected as one of the channels by the TV section 1 and controlled to be reproduced, and the VTR section 2 can be operated by the so-called one-touch channel selection operation of the TV section 1 without being aware of the reproduction operation of the VTR section 2. Can be played.

(C) If the TV section 1 or the VTR section 2 performs a tuning operation while the VTR section 2 is playing, this operation is performed when the tape program is finished and the television program is watched.
The playback of the R section 2 is stopped, and the TV section 1 and VTR are
In any channel selection operation of the section 2, the tuners 3 and 16 are both synchronized with the channel selected, and the VTR section 2 switches from the tape reproduction output to the television tuner output of the selected channel, and the CRT 10 The display screen of changes to the broadcast of the selected channel.

Since the tuning operation can be performed from either the TV unit 1 or the VTR unit 2, the display screen of the VTR unit 2 during reproduction is confused with the screen of the TV unit 1 when it is used alone. Even if you perform the tuning operation in 1, the display screen will switch to the selected channel, and you will not be confused by the operation.

(D) When the recording operation of the VTR unit 2 is performed, V
The TR section 2 starts recording the built-in tuner 16, and the TV section 1
Switches the input source to the built-in tuner 3 and displays the broadcast of the reception channel of this tuner 3 on the CRT 10. Since the screen display before recording is the received broadcast of the tuner 16, the broadcast can be surely recorded without performing the channel synchronization operation of the VTR unit 2.

Moreover, since the channels of the tuners 3 and 16 before recording are synchronized, the broadcast displayed on the CRT 10 does not change even if the input source of the TV section 1 is switched by recording.

(E) If the TV section 1 or the VTR section 2 performs a channel selection operation during recording of the VTR section 2, the change of the recording channel due to this operation is prohibited, so that the channel of the tuner 16 does not change. The tuner 3 changes to the selected channel, and the broadcast of the selected channel is displayed on the screen of the CRT 10.

Since the tuning operation can be performed from either the TV section 1 or the VTR section 2, (for example, it is confusing that the recording screen of the VTR section 2 is displayed, the VTR section 2 performs the tuning operation. However, the display screen of the CRT 10 is switched to the selected channel, and there is no confusion with the operation.

(F) When the recording stop operation of the VTR section 2 is performed, the VTR section 2 stops recording and the tuner 16
Is synchronized with the channel currently displayed on the tuner 3 screen,
Moreover, the input source of the TV section 1 is switched to the VTR section 2 again. Then, since the channel displayed on the CRT 10 does not change due to the recording stop operation, careless channel change does not occur.

(Other Embodiments) Next, other embodiments will be described with reference to FIGS. 1, 6 and 7. This embodiment is different from the first embodiment in the control method of the control unit 13 in FIG. 1, and the operation will be described below using the reference numerals in FIG.

The same processing as 16 to B21 is performed. When the TV section 1 receives a channel selection information from the TV section 1 and the channel information is notified from the TV section 1, the process proceeds from step D4 to step D14 and it is determined whether or not recording is in progress.

If recording is in progress, the channel change of the tuner 16 is prohibited, and the current state is maintained without doing anything. On the other hand, if recording is not in progress, the process proceeds from step D14 to step D12, and the processes of steps D12 and D13 are performed.

Next, when a recording operation of the VTR section 2 by the operation section 19 occurs, steps D5 to D15
Then, the TV section 1 is notified of the occurrence of the recording operation, and when the channel information is notified from the TV section 1 based on this notification, the channel is notified to the tuner 16 by going to Step D17 via Step D16. , And notifies the TV section 1 of the completion of the channel setting in step D18, and then controls the recording / reprocessing section 17 to record in step D19 to record the received broadcast of the tuner 16. When a recording stop operation of the VTR section 2 by the operation section 19 occurs, the process moves from step D6 to step D20 to notify the TV section 1 of the occurrence of the recording stop operation, and then step D21.
Thus, the recording / reprocessing unit 17 is controlled to stop and the recording is ended.

(III) Operation of the entire apparatus (a) When both the TV section 1 and the VTR section 2 are turned on, the display screen of the CRT 10 does not change.
