Description

The present invention relates to a broadcast receiving apparatus and a program including output control means for outputting emergency information when it is detected that emergency information necessary for an emergency is included in the broadcast while receiving the broadcast.

In general, when a disaster such as a large earthquake or tsunami occurs, each broadcast media (radio station, television station) broadcasts an emergency bulletin even during the program as one form of reporting. That is, when an emergency occurs, broadcast corresponding to emergency information including necessary emergency information is performed. Broadcasts corresponding to such emergency bulletins (emergency information) are broadcast on AM / FM radio broadcasts, terrestrial analog / terrestrial digital TV broadcasts, and BS analog / BS digital broadcasts. In the case of central broadcasting, emergency response broadcasting is often not performed.

(Embodiment 1)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
This embodiment exemplifies a case where the broadcast receiving apparatus is applied to a mobile phone with a broadcast receiving function, and FIG. 1 is a block diagram showing basic components of the mobile phone with a broadcast receiving function. .
This mobile phone is provided with a telephone function, an electronic mail function, an Internet connection function (Web access function), a TV function, a radio function, an emergency broadcast output control function, and the like. This television function is a broadcast receiving function for receiving a television broadcast transmitted from a television station via a transmission base station, and receives a high-resolution digital television broadcast (12-segment broadcast).

The radio function is a broadcast reception function for receiving a radio broadcast transmitted from a radio station via a transmission base station. The reception state of FM (ultra-high frequency) radio broadcast and the reception state of AM (medium wave) radio broadcast. Can be switched. Note that the types of broadcasts that can be received by the television function and the radio function are not limited to these and are arbitrary. For example, digital ultra high frequency radio broadcasting (for example, 3 segment terrestrial digital radio broadcasting) may be received, or Internet television (for example, regional television) may be received. In addition, the emergency broadcast output control function is an emergency broadcast monitoring function that monitors emergency information broadcast by broadcast media (radio stations, TV stations) as an aspect of news reports when a disaster such as a major earthquake or tsunami occurs, and outputs the emergency information. It is configured to detect whether emergency information necessary for an emergency is included in the broadcast while receiving the broadcast in the background, and output the emergency information when emergency information is detected. Yes.

The central control unit 1 operates by supplying power from the external power supply connection unit 2 or the internal power supply 3, and controls the overall operation of the mobile phone according to various programs in the storage unit 4, a central processing unit, a memory, etc. have. The external power supply connection part 2 has a connection terminal connected to a commercial power supply (AC power supply) or a large capacity battery (for example, a battery pack), and supplies power to each part of the mobile phone. The internal power source 3 has a secondary battery and supplies power to each part of the mobile phone. Note that power is supplied from the external power supply to each part of the mobile phone when connected to the external power supply, and power is supplied from the internal power supply 3 to each part of the mobile phone when the external power supply is not connected. The external power source (commercial power source) is connected via a cradle (charging base) or a power adapter (not shown).

The power supply state detection unit 5 detects the power supply state of the mobile phone as the current state of the mobile phone, whether power is being supplied from an external power supply via the external power supply connection unit 2, or power from the internal power supply 3 Detect if the supply is taking place. That is, the power supply state detection unit 5 detects the power supply state when the power is turned on or when the power supply is switched. In addition to detecting whether the internal power supply or the external power supply is used as the power supply type, When the internal power supply 3 is used and power is supplied from the internal power supply 3, the remaining battery level of the internal power supply 3 is detected. Here, based on the power state of the mobile phone detected by the power state detection unit 5, the central control unit 1 selects a broadcast received in the background for the emergency broadcast monitoring function described above.

That is, when the internal power supply is used as the type of power supply, the central control unit 1 selects a broadcast with low power consumption from among a plurality of broadcasts with different power consumption for background reception. For example, if a plurality of broadcasts are television broadcasts and radio broadcasts, a broadcast with low power consumption (radio broadcast) is selected for background reception. Furthermore, when an internal power supply is used, a broadcast suitable for the current battery level is selected for background reception. For example, if a plurality of broadcasts are television broadcasts and radio broadcasts, the radio broadcast is selected as a broadcast with low power consumption. In addition, when an external power source is used, the central control unit 1 selects a broadcast with a large amount of information from a plurality of broadcasts with different amounts of information. For example, if a plurality of broadcasts are television broadcasts and radio broadcasts, the television broadcast is selected as a broadcast with a large amount of information.

The storage unit 4 stores programs and various applications for realizing the present embodiment in accordance with the operation procedure shown in FIGS. 3 and 4, and stores various information necessary for them. Yes. The storage unit 4 is provided with a selection condition setting storage unit M to be described later. The wireless communication unit 6 takes in a signal from the receiving side of the baseband unit and demodulates it into a received baseband signal during operation of the calling function, and then outputs a sound from the calling speaker SP, and also inputs audio from the calling microphone MC. Is encoded into a transmission baseband signal, and is then sent to the transmission side of the baseband unit for transmission from the antenna. The operation unit 7 inputs a power key, dial input, character input, command input, and the like, and the central control unit 1 executes processing according to an input signal from the operation unit 7.

The broadcast receiving unit 8 is capable of receiving TV broadcasts and radio broadcasts, and includes a radio tuner 9B connected to the radio antenna 9A, a TV tuner 10B connected to the TV antenna 10A, a demultiplexer 11, and an emergency information detection unit. The broadcast signal from the radio tuner 9B and the TV tuner 10B is given to the demultiplexer 11 and separated into video, audio, and data (character data). The emergency information detection unit 12 detects whether or not emergency information necessary in an emergency is included in the broadcast signal from the demultiplexer 11, and gives the detection result to the central control unit 1. Broadcast stations transmit emergency information during disasters such as earthquakes and typhoons. At that time, the emergency information program is transmitted instead of the program being broadcast, or a telop is synthesized with the program being broadcast. Send emergency information.

Radio sound and television sound output from the demultiplexer 11 are transmitted and decoded by the sound signal processing unit 14 constituting the broadcast output unit 13, and then output from the sound speaker 15. The TV video output from the demultiplexer 11 is sent to the video signal processing unit 16 constituting the broadcast output unit 13 and decoded, and then output from the display unit 17. The sound speaker 15 outputs radio sound and television sound, and also outputs a ringtone, an alarm sound, and the like. The display unit 17 uses a high-definition liquid crystal and outputs various types of information such as character information and a standby image in addition to outputting television images.

The power supply to the sound speaker 15 and the display unit 17 constituting the broadcast output unit 13 is cut off when the power key of the operation unit 7 is operated, but the power supply to the broadcast reception unit 8 is cut off from the power key. Is controlled according to whether a long press operation is performed or a short press operation is performed. In other words, the power supply to the broadcast receiving unit 8 is cut off by a long press operation of the power key, but in order to be able to receive broadcasts in the background when the main power is turned off by a short press operation, it is always on standby. Power is supplied and operation is possible. As described above, even when the main power is off, in this embodiment, the detection operation for detecting whether or not emergency information is included in the broadcast is performed while receiving the broadcast in the background. When the emergency information is detected by the above, the power is turned on and the power supply to the sound speaker 15 and the display unit 17 is started. The standby power supply is not limited to the external power supply, and may be the internal power supply 3.

FIG. 2 is a diagram for explaining the selection condition setting storage unit M.
The selection condition setting storage unit M stores “intermittent reception setting” as information for controlling a detection operation for detecting whether or not emergency information is included in the broadcast while receiving the broadcast in the background. The “intermittent reception setting” “on” means that the reception operation is intermittently executed, and the “intermittent reception setting” “off” means that the reception operation is always executed. .

When “intermittent reception setting” is set to “on”, the execution interval (** second interval) for executing the above-described reception operation is set at a rate of once every second. . The execution interval of the “intermittent reception setting” can be changed according to the remaining battery level when a battery is used as a power source. That is, the central control unit 1 is configured to be able to receive a broadcast selected for background reception intermittently or to control the operation of the broadcast receiving unit 8 so that the broadcast can be always received. In this case, the central control unit 1 sets them in an operable state together with the power supply to each unit constituting the broadcast receiving unit 8.

Next, the operation concept of the mobile phone according to the first embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. This also applies to other embodiments described later, and in addition to the recording medium, an operation specific to this embodiment can be executed using a program / data supplied externally via a transmission medium.

FIG. 3 is a flowchart showing an outline of the overall operation of the mobile phone that is started when the power is turned on (on).
First, when a power-on operation is performed by the power key of the operation unit 7, the central control unit 1 supplies power from the external power supply connection unit 2 or the internal power source 3 to each unit of the cellular phone, and controls each unit of the cellular phone. A power-on process, such as initializing a predetermined memory, is performed (step A1 in FIG. 3). Then, the process proceeds to background reception processing for receiving the broadcast in the background (step A2).

FIG. 4 is a flowchart for explaining in detail the background reception process (step A2 in FIG. 3) for receiving a broadcast in the background.
First, the central control unit 1 operates the power supply state detection unit 5 to acquire the type of power supply as a detection result of the power supply state (step B1 in FIG. 4). That is, whether the internal power supply 3 is used or whether the external power supply is used via the external power supply connection unit 2 is acquired as a power supply state, and the internal power supply 3 is used as the type of power supply based on this power supply state. Is determined (step B2). If an external power supply is used (NO in step B2), a broadcast with a large amount of information is selected for background reception from a plurality of broadcasts with different amounts of information (step B4). In this case, for example, a television broadcast is selected for background reception as a broadcast with a large amount of information.

If the internal power supply 3 is used (YES in step B2), the remaining battery level of the internal power supply 3 is acquired from the power supply state detection unit 5 (step B3). Then, it is checked whether or not the remaining amount of the battery is less than a predetermined amount (for example, less than 1/3) (step B5). If the remaining amount is sufficient with the predetermined amount or more (NO in step B5), the above-described step B4 Then, a broadcast with a large amount of information is selected for background reception, but if the remaining battery level is less than a predetermined amount (YES in step B5), the power consumption is low from among a plurality of broadcasts with different power consumption. Broadcast is selected for background reception (step B6). In this case, for example, a radio broadcast is selected for background reception as a broadcast with low power consumption.

Then, it is checked whether the “intermittent reception setting” in the selection condition setting storage unit M is “ON” (step B7). If the “intermittent reception setting” is “OFF”, the broadcast selected for background reception is used. After the broadcast receiving unit 8 is controlled so that it can be always received (step B8), the flow exits. If “intermittent reception setting” is “ON” (YES in step B7), it is checked whether the internal power source 3 is used as the battery type (step B9). If the external power source is used, After controlling the broadcast receiving unit 8 so that the broadcast selected for background reception can be received at all times (step B13), the process goes out of this flow, but if the internal power supply 3 is used (YES in step B9). Then, it is checked whether the battery remaining amount is less than a predetermined amount (step B10). Here, if the remaining battery level is equal to or greater than the predetermined amount, the background is always received (step B13). If the remaining battery level is less than the predetermined amount (YES in step B10), The execution interval (** second interval) of “intermittent reception setting” is changed based on the remaining battery level (step B11). For example, if the remaining battery level is 3/4 or more, the execution interval is changed to 0.5 second interval, and if it is within the range of 1/4 to 3/4, it should be 1 second interval or less than 1/4. For example, change the interval to 2 seconds.

Then, the broadcast receiving unit 8 is controlled so that the broadcast selected for background reception can be intermittently received (step B12), and the flow is exited. The background reception process is started at every execution interval of the “intermittent reception setting” described above.

When such background reception processing is completed (step A2 in FIG. 3), standby processing for reading and displaying a predetermined standby image or performing location registration by communicating with a base station is performed. Perform (Step A3). In this standby state, when an incoming call is detected from the wireless communication unit 6 (YES in step A4), an incoming call notification is performed, and then a call process for making a call ready in response to an off-hook operation is performed (step A5). Further, when switching of the power source is detected by the power source state detection unit 5 by connection / release of the external power source in the standby state (YES in step A6), the process proceeds to the background reception process described above (step A2). As described above, the background reception process is a process that is executed every time it is detected that the connection to the external power supply and the connection to the external power supply are released.

If it is detected that an emergency signal is included in the broadcast received in Backland (YES in Step A7), a voice message and a display message for notifying that an emergency has occurred are output. (Step A8), it is checked whether the broadcast received in the background is a broadcast with a large amount of information (Step A9). If the broadcast received in Backland is a broadcast with a small amount of information (NO in Step A9), reception of a broadcast with a larger amount of information than this broadcast is started (Step A10) and received in Backland. The parallel output for outputting in parallel the broadcast with a small amount of information and the broadcast with a large amount of information is started (step A11).

For example, a fixed message such as “Now an emergency has occurred” or “Notify. Emergency earthquake warning is being broadcast now. Immediately after the output of such a message, a broadcast received in the background (for example, a radio broadcast) and a broadcast with a larger amount of information (a television broadcast) are output in parallel. In this case, radio broadcasting instead of television sound and television video are output in parallel. Further, if the broadcast received in the backland is a broadcast with a large amount of information (YES in step A9), broadcast output is started to output the broadcast content as it is (step A12).

On the other hand, it is checked whether any operation has been performed in the standby state (step A13 in FIG. 3). If any operation is performed, it is determined whether the operation is a power-off operation by the power key of the operation unit 7 (step A14). (NO in step A14), for example, a setting process in the selection condition setting storage unit M, a TV function / radio function activation process, a telephone call process, and the like are performed (step S14). A15). If the power key is turned off (YES in step A14), it is checked whether the power key is pressed long (step A16). If the power key is pressed, the sound speaker 15 is checked. After executing the power-off process for shutting off the power supply including the display unit 17 and the like (step A17), this flow is ended, but when the power key is pressed for a short time (NO in step A16). Then, the main power is turned off, and the process proceeds to step A18 to receive the broadcast in the background.

In this main power-off state, a detection operation is performed to detect whether or not emergency information is included in the broadcast while receiving the broadcast in the background. (YES in step A19), a power-on process is executed in conjunction with detection of emergency information, and power supply to the sound speaker 15 and the display unit 17 is started (step A20). And it moves to step A8, and after outputting the voice message and display message which alert | report that the emergency happened, the broadcast output which outputs the broadcast content of an emergency is started (step A9-A12).

As described above, in the first embodiment, when detecting that emergency information is included in the broadcast while receiving the broadcast in the backland, the detection can be performed efficiently and reliably. Can be practically effective. In other words, since the broadcast received in the background is selected based on the situation of the mobile phone, the broadcast for background reception can be changed according to the change in the situation, and the emergency information can be changed from the changed broadcast. Detection can be performed efficiently and reliably.

Since the broadcast received in the background is selected based on the power supply state detected by the power supply state detection unit 5, the appropriate broadcast is selected from the relationship between the power consumption by the background reception and the current power supply state. Can do.

When selecting a broadcast to be received in the background, if the internal power supply 3 is used, a broadcast with low power consumption is selected. Therefore, if there is anxiety about the power state, the power consumption is lower. Broadcast can be selected, and power consumption in background reception can be suppressed as much as possible.

When selecting a broadcast to be received in the background, if a battery is used as a power source, a broadcast suitable for the remaining battery level is selected from a plurality of broadcasts with different power consumption. The remaining amount can be used effectively to make the background reception last longer.

When selecting a broadcast to be received in the background, if an external power supply is used, a broadcast with a large amount of information is selected. When a broadcast with a large amount of information was originally received, Can be output immediately.

Since the power supply state is detected when the power supply is switched, it is not necessary to constantly monitor the power supply state, and the monitoring can be minimized.

Since the detection operation for detecting whether or not emergency information is included in the broadcast while being received in the background is intermittently operated, power consumption can be suppressed.

When using a battery as a power source and receiving a broadcast in the background while intermittently detecting whether the broadcast contains emergency information, the interval of the intermittent operation is set as the remaining battery level. Since the change is made accordingly, if the remaining battery level is low, the execution interval of the intermittent operation can be lengthened, and the background reception can be prolonged by effectively using the small remaining battery level.

When it is detected that emergency information is included in the broadcast while receiving the broadcast in the background, the broadcast content received in the background and a broadcast with a larger amount of information than this broadcast are received. Since the broadcast contents are output in parallel, the emergency situation can be notified to the user in a multifaceted and effective manner.

In the state where the commercial power supply (AC power supply) or the large capacity battery is connected via the external power supply connection unit 2, the broadcast reception unit 8 receives power from the external power supply as a standby power supply even when the main power supply is off. When it is in an operable state, when it is detected that emergency information is included in the broadcast being received in the background, the power is turned on and the broadcast content is output. Even when the main power is off, the occurrence of an emergency can be notified immediately.

When emergency information is detected, a message is sent to notify the occurrence of an emergency, so it is possible to immediately notify that an emergency has occurred, and users are confused by sudden emergency broadcasts. Without having to deal with it.

In the first embodiment described above, while receiving a broadcast in the background, whether or not emergency information is included in the broadcast is intermittently detected. However, this intermittent operation is performed to detect emergency information. However, the detection operation for detecting the power supply state may be intermittently performed. This is advantageous in that the power consumption is reduced compared to the case where the detection of the power supply state is always performed. Further, when the power supply state is detected intermittently, the execution interval of this intermittent operation may be changed according to the remaining battery level. As a result, a small amount of remaining battery can be used effectively.

(Embodiment 2)
Hereinafter, a second embodiment of the present invention will be described with reference to FIGS.
In the above-described first embodiment, the power state is shown as the state of the mobile phone, and the broadcast received in the background is selected based on the power state of the mobile phone.

Since FIG. 1 described in the first embodiment is the same in the second embodiment, the description thereof is omitted.

FIG. 5 is a diagram for explaining the selection condition setting storage unit M in the second embodiment.
When the selection condition setting storage unit M detects that emergency information is included in the currently received broadcast (first broadcast), the selection condition setting storage unit M selects a broadcast having a larger amount of information than the broadcast as the second broadcast. Then, “second broadcast setting” indicating whether or not to output the broadcast content is stored, and “parallel setting” is stored whether or not the first broadcast and the second broadcast are output in parallel. . Here, “ON” of “second broadcast setting” means that, for example, when the first broadcast is a radio broadcast, after the emergency information is detected, the television broadcast is selected as the second broadcast with a large amount of information and the broadcast is performed. This means that the contents are output. “On” of “Parallel setting” means that, for example, when the first broadcast is a radio broadcast, after the emergency information is detected, the television broadcast is selected as the second broadcast with a large amount of information, and the broadcast content is parallelized. It means to output.

Next, the operation concept of the mobile phone according to the second embodiment will be described with reference to the flowcharts shown in FIGS. FIG. 6 is a flowchart showing an outline of the overall operation of the mobile phone that is started to be executed when the power is turned on (turned on) in the second embodiment.
First, when a power key-on operation is performed, the central control unit 1 supplies power from the external power source connection unit 2 or the internal power source 3 to each unit of the mobile phone, as in the first embodiment described above, and the mobile phone Each section of FIG. 6 is brought into an operable state, and power-on processing such as initialization of a predetermined memory is performed (step C1 in FIG. 6).

Then, a standby process is performed in which a predetermined standby image is read and displayed, or a location registration is performed by communicating with the base station (step C2). In this standby state, when an incoming call is detected from the wireless communication unit 6 (YES in step C3), after receiving an incoming call notification, a call process is performed to make the call ready in response to an off-hook operation (step C4). . Further, when any user operation is performed in the standby state (YES in step C5), if it is an operation other than an operation instructing to start receiving a broadcast (NO in step C6), a process corresponding to the operation is as follows: For example, a setting process to the selection condition setting storage unit M, a telephone call process, and the like are performed (step C7).

If any operation is performed, if it is an operation for instructing the start of broadcast reception (YES in step C6), the broadcast reception unit 8 is set in an operating state and reception of a radio broadcast or a television broadcast is started. (Step C8), a broadcast according to a TV channel or radio frequency arbitrarily selected by a user operation is set as a foreground broadcast, and the broadcast content is output (step C9), and then detection for detecting emergency information is detected. The operation is started (step C10).

FIG. 7 is a flowchart for explaining in detail the emergency information detection start process (step C10 in FIG. 6).
First, the central control unit 1 determines whether the broadcast arbitrarily selected by the user operation as described above (foreground broadcast) is a broadcast corresponding to emergency information that broadcasts emergency information when a disaster such as a large earthquake or tsunami occurs. (Step D1 in FIG. 7). Here, whether or not it is a broadcast corresponding to emergency information is determined in advance, for example, whether or not it is a broadcast corresponding to emergency information based on whether the broadcast is less public or the entertainment is strong You may make it discriminate | determine. If it is a broadcast corresponding to emergency information (YES in step D1), this broadcast is received in the foreground and a detection operation for detecting whether emergency information is included is started (step D2).

Then, it is checked whether there is a broadcast being received in the background (step D3). If there is no broadcast being received in the background, the flow of FIG. 7 ends at this point, but the broadcast is being received in the background. If there is a broadcast (YES in step D3), the background broadcast reception is terminated (step D4), and then the flow of FIG. 7 is terminated. If the broadcast is not emergency information compatible (NO in step D1), the emergency information compatible broadcast is selected for background reception (step D5), and then the emergency information detection operation is started while receiving this broadcast. After that (step D6), the flow of FIG. 7 ends.

When the emergency information detection operation is started (step C10 in FIG. 6), when it is detected that emergency information is included in the broadcast being received in the foreground or background (YES in step C11). In response to the detection of emergency information, the process proceeds to emergency information reception processing for effectively informing the occurrence of an emergency such as a large earthquake or tsunami (step C12).

FIG. 8 is a flowchart for explaining in detail the emergency information reception process (step C12 in FIG. 6).
First, the central control unit 1 reads “second broadcast setting” from the selection condition setting storage unit M (step E1 in FIG. 8), and checks whether this “second broadcast setting” is “ON” (step E2). ). If “second broadcast setting” is “off” (NO in step E2), it is checked whether the broadcast whose emergency information has been detected is a broadcast that is being received in the background (step E3), and the foreground is being received. 8 (YES in step E3), the flow of FIG. 8 ends in order to maintain the output state of the broadcast content as it is. However, if the broadcast is not being received in the background (NO in step E3). After starting the output of the broadcast content in place of the broadcast being received in the foreground for the broadcast being received in the background (step E4), the flow in FIG. 8 is ended.

If “second broadcast setting” is “ON” (YES in step E2), the broadcast type of the broadcast currently being received in the foreground or background (first broadcast) is detected, and the amount of information If it is a broadcast with a large amount of information (NO in step E5), the process proceeds to step E3 described above, and if the broadcast is not receiving a background, the background is being received. Is started in place of the broadcast being received in the foreground (step E4).

If the broadcast has a small amount of information (YES in step E5), the second broadcast having a large amount of information is selected (step E6). Then, “Parallel setting” is read from the selection condition setting storage unit M (Step E7), and it is checked whether “Parallel setting” is “ON” (Step E8). If “Parallel setting” is “OFF”. For example, the second broadcast content with a large amount of information is output (step E9). If “parallel setting” is “ON” (YES in step E8), the first broadcast with a small amount of information (for example, After starting the parallel output for outputting the broadcast contents of the radio broadcast) and the second broadcast (television broadcast) having a large amount of information in parallel (step E10), the flow of FIG. 8 ends.

As described above, in the second embodiment, if an arbitrary broadcast selected by the user is an emergency information compatible broadcast, the emergency information compatible broadcast is selected for background reception. Irrespective of the type of broadcast selected as urgent information can be detected.

In the state where the broadcast is received in the background, when the user intends to view or listen to the broadcast corresponding to the emergency information, the broadcast reception by the background is terminated, so that more power saving is achieved. Can be planned.

When it is detected that emergency information is included in the first broadcast that is currently being received, if the first broadcast is a broadcast with a small amount of information, the second broadcast with a large amount of information is selected. Since the broadcast contents are output, the user can confirm more detailed information regardless of the type of broadcast currently being received.

When it is detected that emergency information is included in the first broadcast, the first broadcast and the second broadcast can be output in parallel. It can be communicated in a multifaceted and effective manner.

Since the second broadcast having a large amount of information is selected and whether or not to output the broadcast content is arbitrarily set in advance, emergency information can be output in consideration of the user's intention.

In the second embodiment described above, when emergency information is detected, a message notifying the occurrence of an emergency situation may be output. That is, as in the first embodiment described above, the broadcast content may be output immediately after outputting a voice message and a display message notifying that an emergency has occurred.

In each of the above-described embodiments, a broadcast signal transmitted from a television station / radio station via a transmission base station is received. For example, a television broadcast program or a radio broadcast is transmitted via a wireless communication network or the Internet. A digital broadcast may be downloaded and received from an information distribution server that provides an information service that provides a program.

Moreover, as a kind of television broadcasting, 12 segment broadcasting and 1 segment broadcasting may be sufficient. In this case, a broadcast with low power consumption (1-segment broadcasting) may be selected for background reception. Further, when detecting emergency information, instead of 1-segment broadcasting, 12-segment broadcasting with a large amount of information may be selected and output. The type of television broadcast may be terrestrial analog television broadcast, terrestrial digital television broadcast, BS analog television broadcast, BS digital television broadcast, CS television broadcast, or the like. The type of radio broadcast is not limited to FM (ultra-high frequency) radio broadcast, AM (medium wave) radio, and 3 segment terrestrial digital radio broadcast, but may be other radio broadcasts.

In each of the above-described embodiments, the intermittent reception setting has been described using the expression “execution interval”. However, the ratio of the on time / off time may be variable. Even if the on-time / off-time (duty of on-time) is the same, it is preferable that the on-time + off-time is short because the delay from the emergency information broadcast to reception detection can be shortened on average.

In each of the above-described embodiments, the radio antenna 9A, the radio tuner 9B, the television antenna 10A, and the television tuner 10B are provided. However, a single antenna or tuner may be used.
In addition, the mobile phone is not limited to a mobile phone having a broadcast receiving function, and may be a personal computer / PDA (personal portable information terminal) having a broadcast receiving function, or a broadcast receiving apparatus itself.
