Abstract

PROBLEM TO BE SOLVED: To sense and receive an emergency broadcast immediately through automatic starting and to generate an alarm by performing ON/OFF control over the power source with the control signal outputted by a TV tuner circuit when the emergency broadcast is received. SOLUTION: This personal computer 16 which can perform ON/OFF control over the power source through remote control 11 turns on the power source 15 by a power source control microcomputer 12 when the power-ON output signal is sent out of the remote control 11 to start the personal computer 16. Further, when the TV tuner circuit 14 receives an emergency broadcast radio wave, the TV tuner circuit 14 sends a signal to the power source control microcomputer 12, which once receiving the output signal from the TV tuner circuit 14, turns on the power source 15 of the personal computer with a signal and then sends a signal to BIOS.ROM 13 at the same time to initialize the TV tuner circuit 14 and sounds an alarm at the same time.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a personal computer having a built-in TV tuner circuit, and more particularly to a personal computer having an emergency broadcast receiving function.

[0002]

2. Description of the Related Art At present, when an emergency broadcast such as a disaster is issued on a home television or radio, a television having an emergency broadcast code detecting device, such as a publicly available TV, for example, when a main switch is OFF, is used. , A tuner device, a voice detection device, a code detection device to supply power from a standby power supply,
Always operate, wait for emergency broadcast reception, receive emergency broadcast, immediately return to normal TV reception mode, and when emergency broadcast is sensed, use volume control device and video control device to transmit video and audio. According to a method of automatically adjusting to an optimal state (for example, see Japanese Patent Application Laid-Open No. 58-134588), the power of the television and the radio is automatically turned on,
Emergency broadcasts can be received and alarms can be issued.

[0003] In a personal computer having a built-in multimedia function such as a TV tuner or a FAX modem, it is already known to automatically start the personal computer by receiving a FAX.

[0004]

However, the above-mentioned TV has
In a personal computer with a built-in tuner circuit, there is a problem that a personal computer cannot start an alarm automatically upon detecting an emergency broadcast and issue an alarm upon receiving the emergency broadcast, like a home television.

When an emergency broadcast is sensed by a personal computer, it is necessary to immediately switch to a television function to immediately receive the emergency broadcast and to issue an alarm. It is necessary to forcibly turn on the power, and it is necessary to notify before the broadcast that the emergency broadcast will start. The reason is that, since the broadcast is an emergency broadcast, even if the power of the personal computer is turned off, the emergency broadcast must be immediately issued, and at the same time, it must be notified that the broadcast is an emergency broadcast. is there.

SUMMARY OF THE INVENTION An object of the present invention is to provide a personal computer having a multi-function capable of receiving television broadcasts, which detects an emergency broadcast, automatically starts up, immediately receives the emergency broadcast, and issues an alarm. It is in.

[0007]

According to the present invention, in a personal computer having a television function, a power supply is turned on by a TV tuner circuit having an emergency broadcast receiving function and a control signal output from the TV tuner circuit when receiving an emergency broadcast. And a power supply control circuit for performing / OFF control.

Further, the present invention is characterized in that the personal computer described above further comprises a storage circuit storing a program for automatically starting the personal computer in response to a start signal output from the power supply control circuit.

When the TV tuner circuit detects an emergency broadcast, it outputs a power control signal, and in response to the signal, the power control circuit turns on the power of the personal computer and automatically starts up. Thus, a personal computer having a multi-function capable of receiving a television broadcast can receive an emergency broadcast and issue an alarm even when the power is off.

[0010]

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a personal computer according to the present invention. In FIG. 1, a power supply control circuit corresponds to the power supply control microcomputer 12 in remote control reception, and a storage path storing a program for automatically starting the personal computer 16 is a BI path.
This corresponds to the OS ROM 13.

When a power ON output signal is output from the remote controller 11, the personal computer 16 capable of controlling the power ON / OFF with the remote controller 11 turns on the power source 15 by the power control microcomputer 12 and turns the personal computer 16 on. Can be started. The TV tuner circuit 14, which controls the personal computer 16 so that it can be used as a television, monitors whether or not an emergency broadcast from the broadcast station 17 has arrived.

The emergency broadcast is performed by a television or radio broadcast audio channel, and broadcasts a disaster forecast or occurrence by interrupting a normal program. Therefore, a special code is added before and after the broadcast to distinguish the broadcast from the emergency broadcast. Therefore, the TV tuner circuit 14
Can monitor this special code and know whether or not an emergency broadcast has arrived.

When the TV tuner circuit 14 detects an emergency broadcast wave, the TV tuner circuit 14 sends a signal to the power control microcomputer 12. When receiving the output signal from the TV tuner circuit 14, the power supply control microcomputer 12 turns on the power supply 15 by using a known method of turning on the power supply of the personal computer by the signal. The power control microcomputer 12
After the power supply 15 is turned on, a signal is sent to the BIOS ROM 13 at the same time.

The power supply 15 of the BIOS ROM 13 is turned on.
, The stored program is executed, and the system is started up so that the TV function such as initialization of the TV tuner circuit 14 and adjustment of the speaker volume can be realized. At the same time, by sounding a warning sound, it is possible to notify that the emergency broadcast has been received, to immediately receive the emergency broadcast, and to emit information.

The embodiments of the present invention have been described with reference to the drawings. However, the present invention is not limited to the embodiments, and may be modified without departing from the spirit of the present invention. However, this is included in the present invention.

[0017]

As described above, the present invention provides a TV
In a personal computer with a built-in tuner circuit, even if the power of the personal computer is off, if an emergency broadcast occurs, the personal computer is immediately turned on to automatically start up, execute the TV function, and receive the emergency broadcast. This has the effect that an alarm can be issued, and at the same time, an alarm can be sounded to notify that it is an emergency broadcast.

Therefore, if a personal computer is provided, it is possible to receive an emergency broadcast without newly purchasing a dedicated television for receiving the emergency broadcast simply by adding an option board equipped with this function. As a result, costs and installation space can be reduced. In addition, unlike a large home-use television, since it is space-saving, it can be placed in a necessary place such as a bedroom or a private room without choosing an installation place.
