Abstract

PURPOSE: To serve information to viewers at all times even when no desired channel is presented on a screen by using a notice means to inform it to a viewer when a radio wave including a digital signal is received and displaying the signal onto a character display means. CONSTITUTION: A channel selection signal being a default of a selected channel stored in a RAM 3 is fed to a tuner 6 of a TV broadcast receiver 1. When a digital signal of a video signal of a set channel is received, a buzzer 10 buzzs via a buzzer ring control section 11 to inform it to a viewer. The digital signal includes program information of a teletext broadcast or a TV broadcast station. Then the digital signal is converted into characters and the converted character string is displayed on a character display panel 12 via a character display control section 13. When no digital signal is received, a central processing unit 4 receives a video signal succeedingly. on the reception of an emergency broadcast, the outline of the emergency is recognized by the buzzer 10 and the panel 12 and the picture is set to a set channel, then details are recognized timely.

The purpose is to provide a TV broadcast receiver that can be checked at any time.

[0005]

In order to achieve the above object, the present invention converts a radio wave transmitted from a TV broadcasting station into a video signal, and decodes a video signal by decoding a digital signal from the video signal. Means, notification means for notifying that the digital signal has been received, character display means for converting the digital signal into a character string and displaying the character string, and control means for controlling the respective means. .

[0006] Further, the input means for inputting the information corresponding to the character string displayed on the character display means and the signal transmission section for transmitting the input information from the input means to the TV broadcasting station are provided with the above-mentioned structure. It is a configuration provided.

Further, the above-mentioned structure is provided, and one of the input means is provided.
As an example, the IC card reading unit is provided.

[0008]

According to the present invention, when the electric wave including the digital signal transmitted from the TV broadcasting station is received by the above-mentioned constitution, the notifying means can inform the viewer and the character display means can display it. Therefore, even if the desired channel is not displayed on the screen, it is possible to always provide the viewer with the information transmitted by the digital signal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A TV broadcast receiver according to an embodiment of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 is a block diagram of a TV broadcast receiver of this embodiment.

First, the internal configuration of the TV broadcast receiver 1 of this embodiment will be described. As the control means, there are a ROM 2 for storing a control program, a RAM 3 for storing various data, and a central processing unit 4 for performing various controls based on the contents of the control program in the ROM 2. As a video signal receiving / decoding means, a tuner 6 for selectively receiving and converting a high frequency signal transmitted from the TV broadcasting station 5 into an intermediate wave signal, a video detector 7 for converting the intermediate wave signal into a video signal, and a video signal are provided. There are a digital signal decoding unit 8 for decoding and extracting a digital signal, and a communication control unit 9 for transmitting the extracted digital signal to the central processing unit 4.

Further, a buzzer 10 and a buzzer sounding control section 11 for controlling the sounding of the buzzer 10 as a notification means, and a character for controlling the character display panel 12 and the character display panel 12 as a character display means separately from the original screen of the television. A display controller 13 is provided.

The operation of the above configuration will be described with reference to the flowchart of FIG. In the TV broadcast receiver 1,
First, a channel selection signal is supplied to the tuner 6 (step 1). This is the default value for the selected channel stored in RAM3. The video signal of the channel set in step 1 is received (step 2). Step 2
It is determined whether or not the video signal received in step 1 contains a digital signal (step 3). This digital signal contains
For example, character multiplex broadcasting and TV broadcast program information are included. If there is a digital signal received,
The buzzer 10 is sounded via the buzzer sounding control unit 11 to inform the viewer (step 4). Next, the digital signal is converted into characters (step 5), and the converted character string is displayed on the character display panel 12 via the character display controller 13 (step 6). If the digital signal is not received in step 3 described above, the central processing unit 4 continues to receive the video signal in step 2.

For example, when receiving an emergency broadcast, the buzzer 1
The details of the emergency broadcast can be obtained in a timely manner by knowing the outline with 0 and the character display panel 12 and adjusting the screen to the set channel.

(Embodiment 2) FIG. 3 shows a second embodiment according to the present invention.
An example of is shown. In the TV broadcast receiver 1 of this embodiment, when the digital signal decoding unit 8 decodes the digital signal and the content is a bidirectional program, the sensor 15 receives the signal from the remote controller 14 as the input means. The remote control signal reception control unit 16 reads the data and sends it to the central processing unit 4. After that, the communication control section 9 transmits the signal from the communication modem 18 to the TV broadcasting station 5 via the public line 19 via the signal transmitting section 17. Other configurations are the same as in the first embodiment.

(Embodiment 3) FIG. 4 shows a third embodiment according to the present invention.
An example of is shown. In the TV broadcast receiver 1 of this embodiment, when the digital signal decoding unit 8 decodes the digital signal and the content is a bidirectional program, the IC card reading unit 2 from the IC card 20 via the IC card reader 21.
2, personal information is read out, and the personal information is transmitted as additional information of the remote control signal from the modem 18 to the TV broadcasting station 5 through the public line 19 via the signal transmitting unit 17. The other structure is similar to that of the second embodiment.

As described above, the TV broadcast receiver of this embodiment can receive digital signals in accordance with the selected channel, so that even if the viewer is watching a program of a different TV broadcast station on the TV screen. The start of reception of the digital signal of the selected channel can be confirmed by the sound of a buzzer, and the character display panel allows the user to know the program content on the air of the selected channel.

Further, if the interactive program is started, the channel of the television itself is set to the same selected channel as the TV broadcast receiver, and the remote controller is operated to operate the CPU.
4. A bidirectional program can be used by outputting a signal through the communication controller 9, the signal transmitter 17, and the modem 18.

If the personal information stored in the IC card is output, the TV program can obtain more detailed viewer information by the interactive program.

In the TV broadcast receiver 1 of this embodiment, the notification means is a buzzer, and the buzzer sounds the viewer to confirm the program information of the selected channel, but the buzzer is not the only option. Instead, a lamp such as an LED may be used, and the same effect can be obtained by flushing the display panel.

[0021]

As described above, according to the present invention, it is possible to appropriately confirm information by a digital signal transmitted from the TV broadcasting station of the set channel, and to be able to immediately know emergency disaster information and the like. A TV broadcast receiver can be provided.
