Abstract

PURPOSE:To obtain a CATV terminal equipment by which the operating state of a tuner is easily recognized without erroneous revision of a channel of the tuner in use for recording a program on a different channel. CONSTITUTION:An input RF signal is fed to a TV tuner 12 and a VTR tuner 13. A CPU 15 controls the operation of each tuner by the operation of a tuner selection key. The operating state of each tuner is displayed by a 1st display section 1 and a 2nd display section 2. When a video recording key is depressed, a video recording command is fed to a connected VTR to set the video recording mode. Then the CPU 15 makes the tuner 13 operationable independently of the pressing state of a tuner selection key and a channel of the tuner 13 is locked to light a channel lock display lamp 7. Even when a ten-key is operated in this state, the channel during video recording is unchanged.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a domestic CATV terminal device capable of back-recording with a VTR.

[0002]

2. Description of the Related Art Conventionally, a domestic CATV terminal device has a built-in tuner, but it is preferable to have two tuners built-in for so-called back recording.

Even in the case of having two tuners, it is preferable that the tuning operation can be performed by a common ten key.

However, in the case of having two tuners, there is a risk of erroneous operation in which the channel of the tuner currently used for back recording is erroneously changed.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is no possibility of accidentally changing the channel of the tuner being used for the back recording, and the operating state of the tuner can be immediately understood.
A TV terminal device is provided.

[0006]

According to the present invention, there is provided a first tuner connected to a television receiver, a second tuner connected to a VTR, and operation states of the first and second tuners. First and second display sections for displaying respectively, a set of channel selecting means for commonly selecting channels of the first and / or second tuner, and channel selection of the second tuner while the VTR is recording operation. The CATV terminal device is provided with a channel lock means for prohibiting the channel lock and a channel lock display means for indicating that the channel lock means is in operation.

[0007]

In the present invention, the first and second tuners can be tuned to by the common channel selecting means, and their operating states are displayed on the first and second display sections. Also, VT
During the recording operation of R, the channel lock means prohibits the channel change of the second tuner to prevent an erroneous operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing an operation panel of a CATV terminal device according to the present embodiment, in which 1 is a first display section for displaying an operating state of a TV tuner, and 2 is a first display section for displaying an operating state of a VTR tuner. 2 display unit. 3 is a TV tuner channel display section, 4 is a TV tuner channel selectable display lamp, 5 is a VTR tuner channel display section, 6 is a VTR tuner channel selectable display lamp, and 7 is V
It is a channel lock display lamp of the TR tuner.

FIG. 2 is a view showing a remote control transmitter, in which 8 is a ten-key for selecting a channel, 9 is a tuner selection key, and 10 is a recording key.

Next, a block diagram of the apparatus of this embodiment is shown in FIG. First, the input RF signal is divided into two by the distributor 11, and the tuner 12 for TV and the tuner 1 for VTR respectively.
3 is supplied. On the other hand, the remote control signal from the remote control transmitter is received by the remote control signal light receiving unit 14 and the CPU 15
Entered in. This CPU 15 is the two tuners 1
In addition to controlling Nos. 2 and 13, the TV tuner selectable display lamp 4, the VTR tuner selectable display lamp 5 and the channel lock display lamp 7 are controlled. still,
16 to 18 are drivers for driving the display lamps.

Next, the operation of the apparatus of this embodiment will be described.

When the tuner selection key 9 of the remote control transmitter is pressed, the CPU 15 controls each tuner, so that the tuner 12 to the tuner 13 to the tuner 12 cyclically.
The operable tuners switch in the order of and 13.

Further, the CPU 15 controls each of the drivers 16 to 18 so that the channel selectable display lamp 4 or 6 of the tuner which can be operated corresponding thereto lights up.

When the recording key 10 of the VTR is pressed, a recording command is transmitted to the connected VTR (not shown) to set the recording mode. Then, the CPU 15 makes the tuner 13 operable regardless of the pressed state of the tuner selection key 9, locks the channel of the tuner 13 and turns on the channel lock display lamp 7. Even if the ten key 8 is operated in this state, the channel being recorded does not change.

Therefore, even if the channel selection operation is performed during the reverse recording, the channel of the TV tuner 12 may be changed, but the channel of the VTR tuner 13 is not accidentally changed.

This locked state is automatically released when the recording operation is stopped, and the channel lock display lamp 7
Turns off. Further, even during recording, the lock can be released by pressing the unlock button.

[0018]

As described above, according to the present invention, the operating states of the two tuners can be immediately known, and the erroneous operation of erroneously changing the channel of the tuner being used for back recording can be prevented.
