BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seismic image even if a sound image reproduced from a sound image signal input from an external sound image signal source typified by a video tape recorder or a video game is being viewed. The present invention relates to a television receiver capable of automatically displaying an emergency notification message broadcast when a serious news or the like occurs in video or audio.

[0002]

2. Description of the Related Art Conventional television receivers can be roughly classified into two types with respect to a method of presenting an audiovisual image reproduced from an audiovisual image signal provided from a plurality of viewable audiovisual image signal sources. The first type is 1 on the screen of the monitor that is the video display.
Only the video from the two video image signal sources is displayed, and the audio from the video image signal source is output from the speaker, which is an audio display (for example, refer to Patent Document 1). The second type is one in which the screen of the monitor is divided into a plurality of sub-screens, the images from different audio-visual image signal sources are displayed on each, and the sound from one audio-visual image signal source is output from the speaker. is there. For convenience of explanation, the former (first type) is called a single-screen display television receiver, and the latter (second type) is called a multi-screen television receiver.

In the single-screen display television receiver, only the audiovisual image provided from one audiovisual image signal source selected from the plurality of audiovisual image signal sources is displayed to the viewer. For simplification, the voice output is also expressed as a display in this specification. On the other hand, in a multi-screen television receiver, the video provided by a plurality of audio-visual image signal sources is displayed at the same time as the number of small screens on one screen, but the audio is displayed at a specific video selected. Only those provided by the sound image source are displayed.

[0005]

The single-screen display television receiver and the multi-screen television receiver described above are typified by an emergency telop that is broadcast in order to inform people in the event of a disaster or a serious incident. This section briefly describes the reception and display of the emergency notification message.
The emergency notification message is usually superposed on a radio wave transmitted from a general broadcasting station, or broadcast on a radio wave in the same band.

In a single-screen display television receiver,
When the broadcast station where the emergency notification message is broadcast is selected as the audio-visual image signal source, even when the emergency notification message is started when the normal broadcast content is displayed,
Emergency notification is automatically displayed in video or audio. However, when an external device such as a video tape recorder or a video game is selected as the audio-visual image signal source, the emergency notification message cannot be displayed as video or audio. Even if the single-screen display television receiver can receive the emergency notification message itself, the emergency notification cannot be displayed as a sound image.

As described above, in the single-screen display television receiver, the viewer is activating the television receiver which is a means for receiving and displaying the emergency notification message and reproducing the audiovisual image signal from the external device. If so, the emergency notification message cannot be recognized. Such a situation is extremely problematic when the content of the emergency notification message is emergency information such as earthquake and tsunami information that is associated with human life, or information such as a serious incident.

On the other hand, in a multi-screen television receiver, when an image provided by a broadcasting station is displayed on one or more of the small screens, an emergency notification message can be displayed on the small screen. is there. However, if the emergency notification message is displayed as voice instead of characters or images such as telops, if the small screen is not selected to be displayed as audio, the viewer has received the emergency notification message. I don't know. Further, when the emergency notification message is displayed in characters or images, the small emergency notification displayed on one of a plurality of small screens is unnoticeable, and it is very difficult for the viewer to notice the presence. Thus, unlike a single-screen display television receiver, a multi-screen television receiver can technically display an emergency notification message, but it is said that important information is immediately transmitted to the viewer in an emergency. It is not so different from the single-screen display television receiver that it is very difficult to fulfill the original purpose of the emergency notification message.

Therefore, in view of the above-mentioned problem relating to the reception and display of the emergency notification message in the conventional television receiver, the present invention receives the emergency notification message regardless of the type of the audiovisual image signal source selected. It is an object of the present invention to provide a television receiver that automatically displays an emergency notification message that can be displayed to viewers.

It Needless to say, the emergency notification message may be a broadcast wave transmitted by wire instead of the antenna VS1 such as a cable television.

The emergency notification message receiving system EMa composed of the antenna VS1 and the analog tuner 2a to the message extractor 20a will be described below first, and then the external device image composed of the external input device VS2 and the tuning indicator 22 will be described. The sound image signal input system EIa will be described, and subsequently, the emergency notification message multiple display system MM configured by the image synthesizer 24a and the display 26 for displaying the emergency notification message in a multiplexed manner on the image output from the external input system EIa.
A will be described.

First, in the emergency notification message receiving system EMa, the analog tuner 2a is an analog broadcast wave SW.
A broadcast wave transmitted from a desired broadcast station is extracted from a and output as an intermediate frequency signal SB. The video / audio signal separator 4a converts the intermediate frequency signal SB to the image intermediate frequency signal Svi.
And the audio intermediate frequency signal Sai are separated and output.

The broadcast video receiver 6 receives the video intermediate frequency signal S.
The broadcast video signal Sv is generated from vi. The video A / D converter 8 A / D converts the broadcast video signal Sv to generate broadcast video data Svd.

The broadcast audio receiver 10 generates a broadcast audio signal Sa from the audio intermediate frequency signal Sai. The audio A / D converter 12 A / D converts the broadcast audio signal Sa to generate audio data Sad. Emergency notification voice data storage 1
4, a voice such as a chime that is played to draw the viewer's attention before the emergency notification message is displayed is stored in advance as notification audio data Smd. And
The emergency notification voice data storage 14 stores the notification voice data Sm.
d is supplied to the voice comparator 18. Display time setter 16
Stores information representing a predetermined time T as time data ST. Then, the display time setting device 16 supplies the time data ST to the audio comparator 18.

The voice comparator 18 is a voice A / D converter 12
Voice data Sad input from the
md is compared, and the audio data Sad is the notification audio data S
When it matches with md, it is determined that the emergency notification message is received, and the emergency notification message reception detection signal SE is generated. Further, the voice comparator 18 determines that the time data ST
The emergency notification message reception detection signal SE is continuously output to the message extractor 20a during the predetermined time T represented by.

In response to the emergency notification message reception detection signal SE, the message extractor 20a displays an image of an emergency notification message such as an emergency telop included in the broadcast video data Svd input from the video A / D converter 8. The signal Sm is extracted and output to the video synthesizer 24a. Since the message signal Sm is continuously input during the predetermined time T defined by the time data ST, the message extractor 20a extracts the emergency notification message included in the broadcast video signal Sv over the predetermined time T. it can.

On the other hand, when the emergency notification message ends before the elapse of the predetermined time T, the message extractor 20a has a predetermined capacity so as to output the already extracted emergency notification message as the message signal Sm. A frame buffer may be provided. As an example of a method of generating the message signal Sm, the message extractor 2
For 0a, the broadcast video data Svd output from the video A / D converter 8 is accumulated in the frame buffer, and only the portion of the accumulated video information having the white color information at the top of the screen is extracted as a telop character. There is a method.

Next, in the external device audio / video image signal input system EIa, the channel selection indicator 22 decides to receive the emergency notification message in advance in response to the audio / video image signal Sve input via the external input device VS2. A channel selection signal SBC for instructing the reserved broadcasting station is output to the analog tuner 2a. As a result, while the television receiver EBa is displaying the audio-visual image signal from the external device, the broadcast wave S in which the emergency notification message may be transmitted in the background is transmitted.
Wa can continue to be received. Therefore, when the emergency notification message is actually transmitted, the emergency notification message is superimposed and displayed on the image from the external device without delay, so that the viewer can recognize the emergency notification message without delay.

The emergency notification message multiple display system M
In Ma, the video synthesizer 24a superimposes the message signal Sm on the audiovisual image signal Sve input from the channel selection instructor 22 to generate the audiovisual image signal Svem. Based on the sound image signal Svem, the display unit 26 displays an emergency notification message on the screen of the display unit 26 at a fixed rate. Therefore, even in a multi-screen television receiver, by displaying the emergency notification message over a plurality of sub-screens, it is possible to effectively draw the viewer's attention.

Next, with reference to the flow chart shown in FIG. 2, the emergency notification message automatic display operation by the television receiver EBa will be described.

In step S4, the tuning indicator 22 outputs a tuning signal SBC to the analog tuner 2a. Then, the control proceeds to the next Step S6a.

In step S6a, the analog tuner 2a extracts the intermediate frequency signal SB from a predetermined broadcasting station from the analog broadcasting wave SWa in response to the channel selection signal SBC. Then, the control proceeds to the next Step S8a.

At step S8a, the broadcast video data Svd is generated by the video / audio signal separator 4a, the broadcast video receiver 6, and the video A / D converter 8, and the video / audio signal separator 4a and the broadcast audio are generated. Receiver 10,
And the audio A / D converter 12 causes the audio data Sa
d is generated. Then, the control proceeds to the next Step S10.

In step S10, the voice comparator 18
Thus, it is determined whether the audio data Sad matches the notification audio data Smd. If it is determined that they do not match, the control returns to step S8a described above. On the other hand, if it is determined that they match, the control proceeds to the next step S12.

In step S12, the voice comparator 18
Generates an emergency notification message reception detection signal SE based on the time data ST. Then, the emergency notification message reception detection signal SE remains in the message extractor 2 for a predetermined time T.
It is output to 0a. Then, the control is performed in the next step S14.
Proceed to.

In step S14, the message extractor 20a extracts the emergency notification message from the broadcast video data Svd in response to the emergency notification message reception detection signal SE, and generates the message signal Sm. The message signal Sm is output to the video synthesizer 24a. And
The control proceeds to the next step S16.

In step S16, the image synthesizer 24
a synthesizes the image signal Sve with the message signal Sm to generate the image signal Svem. Then, the control proceeds to the next Step S18.

In step S18, the display device 26 displays an image in which an emergency notification message is multiplexed on a video image provided from the outside based on the sound image signal Sve.
Then, the control returns to step S8a described above to prepare for the next emergency notification message.

As mentioned above, the television receiver EBa

Further, the voice comparator 18 continues to output the emergency notification message reception detection signal SE to the message extractor 20b for the predetermined time T represented by the time data ST.

In response to the emergency notification message reception detection signal SE, the message extractor 20b extracts the image of the emergency notification message such as the emergency telop contained in the additional information IS from the video / audio data separator 4b as the message signal Sm. And outputs it to the video synthesizer 24b. Since the message signal Sm is continuously input for a predetermined time T defined by the time data ST, the message extractor 2
0b can extract the emergency notification message included in the additional information IS over a predetermined time T. Message extractor 20b
Similarly to the message extractor 20a, when the emergency notification message ends before the predetermined time T elapses, the already extracted emergency notification message is output as the message signal Sm so that the frame having a predetermined capacity is internally generated. A buffer may be provided.

In the emergency notification message multiple display system MMb, the image synthesizer 24b adds a message signal Sm input from the emergency notification message receiving system EMb to a video image signal Sve input from the external device video image signal input system EIa.
