  In the following description, the above 1) a mobile phone incorporating a TV reception function will be described as a representative example.

(Constitution)
An information processing apparatus 1 that is a first embodiment of an information processing apparatus according to the present invention includes a key input unit 17 that is an operation unit in FIG. 1 and a control unit 16 that is connected to the operation unit and controls the entire operation. Have.

  In the information processing apparatus 1, as a configuration for a mobile phone that is a mobile communication unit, an antenna 11 is connected to an RF circuit 14 including a down converter and an up converter via amplifiers 12 and 13, and this input / output is a baseband circuit. The speaker 19 and the microphone 20 are further connected to the baseband circuit 15. FIG. 1 also shows an example of a base station 41 that makes a call via the antenna 11 and a mobile phone 42 that is another mobile station that makes a call via the base station 41.

  Further, the information processing apparatus 1 includes a tuner unit 24 connected to the antenna 11 described above as a configuration included in a portion surrounded by a solid line as a configuration for a TV receiver such as a digital terrestrial broadcast, Is connected to the MPEG decoder 25 for decoding MPEG information, the EPG acquisition unit 32 connected to the tuner unit 24 for acquiring EPG information, the output of the MPEG decoder 25 and the image output of the baseband circuit 15 described above. It has a switching unit 22 and a display 18 to which the output of the switching unit is selectively supplied. The display 18 is connected to a luminance setting unit 31 that sets the luminance of the display 18 according to the control of the control unit 16. Furthermore, the information processing apparatus 1 has a switching unit 23 that is supplied with the audio output of the baseband circuit 15 and the audio output of the MPEG decoder 25 and selectively outputs them to the earphone terminal 21 or the like. .

  In the information processing apparatus 1 shown in this embodiment, two power sources connected to the battery 28 are prepared. In FIG. 1, a power source 1 and a power source 2 are shown, respectively. The power source 2 supplies power to the tuner unit 24 and the MPEG decoder 25 that are used only for watching TV, and the power source 1 supplies power to parts other than the power source 2. The switch 27 turns on / off the power source 1 and the power source 2 under the control of the control unit 16, and the switch 26 turns on / off only the power source 2 under the control of the control unit 16.

(Operation)
The operation of the information processing apparatus 1 according to the present invention having the above-described configuration will be described in detail below using a flowchart. First, when the information processing apparatus 1 turns on the switch 27 illustrated in FIG. 1, the switch 26 is activated in an off state. Next, when the user presses a dedicated button or the like that is independent of the key input unit 17 in order to view the TV, it is considered that a TV viewing request has been made (S11), the switch 26 is turned on and the tuner unit 24 is turned on. Power is supplied to the MPEG decoder 25 (S12).

  Next, based on the broadcast signal received and demodulated by the tuner unit 24 and the MPEG decoder 25, the EPG acquisition unit 32 extracts SI / PSI information in the broadcast signal, generates an electronic program guide (hereinafter referred to as EPG), and displays it. It is displayed on the part 18 (S13).

  Here, SI (Service Information) is program arrangement information, and is various information defined for the convenience of program selection. It is defined by the Ordinance of the Ministry of Internal Affairs and Communications, and the contents are defined as the ARIB standard. In addition to the extension part unique to the ARIB standard, MPEG-2 PSI information is also included.

PSI (Program Specific Information) is program specific information, which is information necessary for selecting a required program, and is composed of four tables: PAT, PMT, NIT, and CAT. It is defined in the MPEG-2 Systems standard, the Ordinance of the Ministry of Internal Affairs and Communications.

  Next, according to the displayed EPG information, when the user selects a program to be viewed (S14), the tuner unit 24 is controlled according to the SI / PSI information to select a desired channel (S15). On the other hand, if no program has been selected, the program (channel) viewed last time is selected (S26). At this time, the information for selecting the program that was viewed last time has been lost, the user has not turned on the power for a long time, or moved to another broadcast area, etc. When a program (channel) cannot be selected, a predetermined channel set in advance is presented.

  Next, in order to display the TV image on the display, the switching circuit 22 is switched to select the TV image, and the switching circuit 23 is switched to output the sound to the earphone so as to output the sound (S16).

  If there is no incoming call (S17), the process returns to step S26, and the program currently being viewed is continuously provided as it is. On the other hand, when there is an incoming call, in order to notify the user that the incoming call has been received, the switching circuit 22 is switched to display a screen indicating that the incoming call has been received (S18).

  The image display indicating the incoming call may be overlapped on the TV screen, or the TV screen may be deleted and only the incoming call screen may be displayed. The incoming call display screen may be generated by the baseband circuit 15 or by the control unit 16 or a peripheral circuit.

  Next, the switch 26 is turned off (S19), and the power to the tuner unit 24 and the video / audio decoding circuit 25 is stopped. As a result, the power from the power supply unit is supplied only to the mobile phone function as the mobile communication unit, and it is possible to make a reliable call even if the capacity of the battery 28 is insufficient.

  Next, the call waiting timer is reset (S20). The call waiting timer may be realized by a program of the control unit 16 or may be performed using a dedicated timer circuit (not shown).

  When the call is started (S21), the call is performed with the power supply to the tuner unit 24 stopped until the call is ended (S24). When the call is ended, the switch 26 is turned on again. Thus, broadcast reception is resumed (S25).

  On the other hand, if the call has not been started (S21), the timer has passed a predetermined period (S22), or if the incoming call has been cut off (S23), the switch 26 is turned on again, and broadcast reception is resumed ( S25). If the timer has not passed the predetermined period (S22) and the incoming call is not interrupted (S23), whether or not a call is made is monitored by step 21.

  As described above, by stopping the power supply to the broadcast receiving function in response to an incoming call in the mobile communication unit, power consumption can be reduced, and even if there is no room in the power capacity of the battery 28, it is reliable. It is possible to make a call.

  In step 18, when a call is received while watching the program, the user confirms the operation such as pressing the call button when the incoming call screen is displayed according to the control of the control unit 16. It is also preferable to stop the power supply to the tuner unit 24, the MPEG decoding circuit 25, and the like.

  Furthermore, as described above, in order to reduce power consumption, the following method is suitable in addition to stopping the power supply to the tuner unit 24, the MPEG decoding circuit 25, and the like. In other words, at the timing of step 19, it is preferable that the tuner unit 24 change the process from the high-quality 13-segment broadcast decoding process, which consumes much power, to the one-segment broadcast decoding process, which consumes less power. It is. Further, in step 25, the process is returned from the 1-segment decoding process to the 13-segment decoding process.

  In addition, instead of immediately changing from 13 segments to 1 segment in step 19, it is also preferable to suggest changes to the user by displaying them on the display 18, and to change only when an operation for agreeing to this is obtained. .

  Further, the display 18 can obtain a high-quality image of TV broadcast by setting a high luminance, but also consumes a large amount of power, which is a burden, so in step S18, the luminance of the display 18 is reduced. It is also preferable to reduce power consumption. Here, the luminance setting unit 31 changes the luminance of the display 18 in accordance with the control signal of the control unit 16. Similarly, it is also preferable to change the brightness of the display 18 after proposing the change on the display 18 after obtaining an operation from the user who agrees.

  As shown above, when there is an incoming call from a mobile phone, it is possible to perform reliable call processing even if the battery capacity is insufficient by performing processing such as stopping the power supply related to the broadcast receiving function. it can.

(Other actions)
Further, in the flowchart shown in FIG. 3, a modified example of the operation of the other information processing apparatus 1 is shown. That is, in FIG. 3, the process up to step S18 is the same as that shown in the flowchart of FIG. Compared with the case where the incoming call is displayed in step 18 and the switch 26 is immediately turned off in the flowchart of FIG. 2 to stop the power supply to the broadcast reception process, the control unit 16 and the dedicated dedicated not shown in the flowchart of FIG. The telephone waiting timer by the timer circuit or the like is reset (S31). When a call is started (S32), for the first time, the switch 26 is turned off to stop the power supply to the broadcast receiving process (S35). If the telephone call is not made (S32), the incoming call is cut off (S34), or if the incoming call is not cut off, if the timer elapses for a predetermined period (S33), the process returns to step S26 again to continue receiving the broadcast ( S26).

  When the switch 26 is turned off (S35) and then the call is terminated (S36), the switch 26 is turned on again and the broadcast reception is resumed (S26).

  Similarly in the above procedure, the power supply to the broadcast receiving function is stopped in response to the incoming call, so that the power consumption can be reduced and the power capacity of the battery 28 has no margin. It is possible to make a reliable call.

<Second Embodiment of Information Processing Device According to the Present Invention>
The second embodiment of the information processing apparatus according to the present invention automatically acquires EPG information of a broadcast signal when the broadcast receiving unit is not receiving and the mobile communication unit is not making a call. Show. FIG. 4 is a block diagram showing another example of the configuration of the information processing apparatus according to the present invention, and FIGS. 5 to 8 are flowcharts showing another example of the EPG information acquisition process of the information processing apparatus according to the present invention. It is.

(Summary)
When acquiring SI / PSI information in a broadcast signal, which is necessary for channel selection or EPG display, there is a limit on the transmission rate of SI / PSI information. . For example, in the ARIB standard, the operation regulations, etc., there are 3 to 6 minutes with a long transmission cycle of SI / PSI information.

  That is, the user performs an operation for watching TV, and after the power is provided to the circuit used only for receiving the broadcast, such as the tuner unit 24 and the video / audio decoding circuit 25, the SI / PSI information in the broadcast signal As a worst case, EPG cannot be presented for several minutes as the worst value, and since there is no EPG, viewers cannot perform program selection operations, and information for channel selection cannot be obtained. It is also possible that TV display is not possible. For this inconvenience, the following processing is performed in the second embodiment.

  First, part or all of the SI / PSI information received during the previous TV viewing is stored in a storage area such as the control unit 16. SI / PSI information includes information essential for channel selection (for example, frequency information of each channel) and additional information such as the name of a program broadcast on each channel, and stores additional information. Is stored in accordance with the amount of memory that can be used as the nonvolatile memory of the information processing apparatus. Here, the non-volatile memory means that the viewer does not disappear even when the power switch 27 is turned off. In addition to the memory that does not disappear even if power is not provided, such as an EEPROM, the power switch 27 cannot be turned off. A memory to which power is provided may be used.

  Normally, information essential for channel selection (for example, frequency information of each channel) does not change so much, and in this way, the viewer performs an operation for watching TV, and the tuner unit. 24. After power is provided to a circuit used only for receiving a broadcast such as a video / audio decoding circuit 25, it is considered that channel selection can be performed using SI / PSI information received during the previous TV viewing. It is done.

  However, the names of programs broadcast on each channel are often updated daily, and if the power is off (days) is long, it may be inappropriate as data for EPG display. is there.

  Next, it is assumed that the information processing apparatus according to the present invention is portable and moves. The SI / PSI information differs in each region, particularly in the case of terrestrial digital broadcasting. That is, for example, if a user who normally uses this unit in the Kanto region moves to the Kansai region, the SI / PSI information will be completely different, and after the move, the user will select using the previous SI / PSI information. Can not do the station. In this case, it is necessary to acquire SI / PSI information of the area after moving again, and there is a problem that it takes time to acquire again.

  For this reason, in the second embodiment, EPG information is automatically acquired when the tuner unit that is a TV reception function and the mobile communication unit that is a mobile phone function are not operating.

  The block diagram of FIG. 4 is basically the same as the block diagram of FIG. 1, but in particular, the control unit 1 stores an EPG acquisition control program described in the following flowchart, and realizes the procedure described later. To do. Further, it is shown that a power switch 29 is newly provided to control the MPEG decoder 25 independently.

(Operation)
A second embodiment will be described with reference to the flowchart shown in FIG. This flowchart is processed when the switches 26 and 29 are in the OFF state, such as when the mobile phone is waiting or when the mobile phone is talking.

  First, the presence / absence of watching TV is detected. If the user is not watching TV (S41), the timer is reset (S42). This timer may be realized by a program of the control unit 16 or may have a dedicated timer circuit (not shown). Next, the count value of the timer is inspected, and if a predetermined time has elapsed (S43), the switch 26 is turned on (S44), and the tuner unit 24 or the like is used only for watching TV. Power supply to the circuit block is started, and power supply to the circuit block used for extracting SI / PSI information from at least the broadcast signal is started. Since the TV display is not performed, the switch 29 for supplying power to the decoding circuit for video and audio remains off. Then, the EPG acquisition unit 32 extracts SI / PSI information from the broadcast signal (S45).

  When the extraction of SI / PSI information is completed (S46), electronic program information (EPG) is generated based on the extracted SI / PSI information, the switch 26 is turned off (S47), and the process returns to step S41 again.

  Note that the determination in step S46 may be a method of extracting while determining whether or not all SI / PSI information has been updated, and since the extraction is repeated by a timer thereafter, extraction of a predetermined time is performed. It is also possible to end the process.

  In addition, when acquiring SI / PSI information, that is, EPG information, in step S45, it is also preferable to display on the display 18 that acquisition is in progress. Further, when the acquisition is completed, it is also preferable to display that the EPG information has been acquired.

  As described above, the EPG information may be acquired from the broadcast signal using the tuner unit 24 or the like. However, the EPG information is transmitted to the base station via the RF circuit 14 or the baseband circuit 15 which is a mobile communication unit. It is also preferable that the information is acquired via the station 41 and the Internet. In this case, when acquiring EPG information, it is preferable to supply power only to the RF circuit 14 and the baseband circuit 15 without supplying power to the tuner unit 24 and the like.

(Other actions)
In the case of the flowchart shown in FIG. 6, the switching of the base station is detected, and this is used as a trigger to acquire EPG information.

  First, the presence / absence of TV viewing is detected. If the user is not watching TV (S41), the counter is reset (S42). This counter may be realized by a program of the control unit 16 or may have a dedicated counter circuit.

  Next, it is determined whether or not switching of the base station of the mobile call unit of the information processing apparatus 1 has occurred (S51). If it occurs, the count value is incremented (S52). Next, if the count value of the counter is equal to or larger than the predetermined number (S43), the switch 26 is turned on (S44), and power is supplied to a circuit block such as the tuner unit 24 used only for watching TV. And at least power supply to a circuit block used for extracting SI / PSI information from a broadcast signal is started. Since the TV display is not performed, the switch 29 for supplying power to the decoding circuit for video and audio remains off. Then, the EPG acquisition unit 32 extracts SI / PSI information from the broadcast signal (S45).

  When the extraction of SI / PSI information is completed (S46), electronic program information (EPG) is generated based on the extracted SI / PSI information, the switch 26 is turned off (S47), and the process returns to step S41 again.

  As described above, the EPG information may be acquired from the broadcast signal using the tuner unit 24 or the like, but the base station circuit 15 may be configured to receive the base station via the RF circuit 14 or the baseband circuit 15 that is a mobile communication unit. It is also preferable that the information is acquired via the station 41 and the Internet. In this case, when acquiring EPG information, it is preferable to supply power only to the RF circuit 14 and the baseband circuit 15 without supplying power to the tuner unit 24 and the like.

  In the case of the flowchart shown in FIG. 8, the same processing as in the flowchart shown in FIG. 6 is shown. However, in step S61, if duplicate base stations are detected, the process proceeds to step S43. Is the same as the flowchart of FIG.

  As described above, in the information processing apparatus according to the present invention, the EPG information is originally acquired by automatically acquiring EPG information during a period in which the tuner unit is not receiving a broadcast signal and the mobile communication unit is not in a call. The latest EPG information can be prepared without impairing the broadcast receiving function of the mobile phone or the telephone call function of the mobile phone, and the information processing apparatus and the information processing that exhibit the maximum function among the given power resources A method can be provided.

(Other embodiments)
In some cases, it may differ depending on the area, but assuming that the user is moving on a train, there is a case where an incoming call or a call is prohibited by a railway company. The following is a response when incoming calls are prohibited. FIG. 9 is a block diagram showing another embodiment.

  When the user views the TV while traveling by train, the power supplies 2 and 3 are turned on and the power supply 4 is turned off using the control unit 16 and switches 26, 29, and 30 in FIG. 9. The power supply 4 is supplied to circuit blocks used when the functions of the mobile phone such as the amplifier 12, the amplifier 13, the RF circuit 14, and the baseband circuit 15 are used.

  The following is a response when calls are prohibited. In FIG. 1 or FIG. 4, when a user is watching TV while moving on a train and receives an incoming call, the power supply 2 or 2 or 3 is not turned off immediately, but an on-screen pop-up display is displayed on the screen. Etc. to indicate that there was an incoming call.

  In the pop-up display, there are three types of display of the telephone after moving on the call / answering record / train, and when the user selects the answering record, a message indicating that it is in the answering record state is sent to the calling party. If the user selects the phone after moving by train, a message indicating that the call is made after moving by train is sent to the other party. is there.

  The message such as the recorded message is generated under the control of the control unit 16 and is stored in advance in a memory (not shown). Further, it is assumed that the control unit 16 also controls a memory (not shown) that stores the message of the other party at the time of answering, and when the user makes a reproduction request to the control unit 16 through the key input unit 17 after getting off the train. It is assumed that the message is reproduced from a memory (not shown) that stores the message of the other party.

  With the various embodiments described above, those skilled in the art can realize the present invention. However, it is easy for those skilled in the art to come up with various modifications of these embodiments, and have the inventive ability. It is possible to apply to various embodiments at least. Therefore, the present invention covers a wide range consistent with the disclosed principle and novel features, and is not limited to the above-described embodiments.

  That is, in the above embodiment, the description has been made assuming that there is no overlap between the function of the mobile phone and the circuit that realizes the TV function. However, the baseband circuit 15 and the decoding circuit 25 such as video and audio are digital signal processors. (DSP) may be realized, and in this case, it is not possible to switch between both power sources. However, when the mobile phone function and the TV function have dedicated circuit blocks, the present invention can be implemented by switching the power supply of the dedicated circuit block.

  In the above description, the mobile phone is incorporated with a TV reception function as an example. However, in addition to a dedicated TV receiver or a TV in which a digital broadcast receiving module is connected to a general-purpose device, a mobile phone communication module is additionally provided. The same effect can be obtained even if the is incorporated. That is, in a TV in which a mobile phone communication module is connected to a dedicated TV receiver, the power supply circuit in the dedicated TV receiver has two or more systems as described above, and communication is performed using the mobile phone communication module. In this case, the power of the TV receiver in the dedicated TV receiver is turned off to reduce power consumption.
