BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus and an information processing method provided with a telephone call function such as a cellular phone and a water receiving function such as a mobile television.

Recently, in terrestrial digital broadcasting, high data rate broadcasting for a stationary TV receiver (hereinafter referred to as 13 segment broadcasting) and low data rate broadcasting for mobile TV receiver (hereinafter referred to as 1 segment broadcasting) will be standardized. This one-segment broadcast receiver includes: 1) a dedicated TV receiver with an emphasis on portability; and 2) a digital broadcast reception module using a general-purpose device such as a personal digital assistant or a personal computer (PC) as a personal information terminal. TV receivers that function as mobile TVs by connecting newly installed devices such as TVs or cards to general-purpose devices, and 3) digital broadcast receivers that incorporate a digital broadcast receiver into the mobile phone and display signals or signal processing functions of the mobile phone. This is assumed.

Here, in the viewing device equipped with both the function of the mobile phone and the function of the digital broadcasting receiver, the power consumption is increased compared to the capacity of the battery, so that the use time is limited, so the countermeasure in the possible range is provided. It is required to prolong it.

Patent document 1 (Japanese Patent Laid-Open No. 2003-111004) discloses a device having both a terrestrial digital broadcast reception function and a mobile telephone function as a portable viewing device. Here, a technique is disclosed in which a television program is recorded in an internal memory when a user performs a call operation when there is an incoming call while watching a television.

However, the above-mentioned conventional technology has a problem that it is not possible to sufficiently save the power consumption, which is a subject of the present invention, only by storing image information of a broadcast program in a memory. In addition, when a telephone function and a digital broadcast reception function are provided together, there is a problem that a function for automatically saving power consumption is not sufficiently provided by assuming a lot of situations in which power consumption increases.

SUMMARY OF THE INVENTION The present invention provides an information processing apparatus having a telephone function and a broadcast receiver function. The present invention provides an information processing apparatus and an information processing method that perform a maximum function with a limited power resource by limiting or automating processing according to a use situation. For the purpose of

An information processing apparatus according to the present invention includes a tuner unit for receiving and demodulating a broadcast signal, a mobile communication unit for making a call with another mobile station by communicating with a base station, a battery unit for supplying power to the tuner unit and the mobile communication unit; And a control unit for controlling the power supply from the battery unit for receiving the broadcast signal when the mobile communication unit receives an incoming call from the base station when the tuner unit receives the broadcast signal.

In addition, the information processing apparatus according to the present invention includes a tuner unit for receiving and demodulating a broadcast signal, a mobile communication unit for communicating with another mobile station by communicating with a base station, and the mobile communication unit without the tuner unit receiving the broadcast signal. Is provided with an acquisition unit for acquiring EPG (electronic program information) when it is not communicating with the base station.

In the above-described information processing apparatus according to the present invention, for example, a tuner section that functions to receive terrestrial digital broadcasting is controlled so that the power supply associated with the reception is reduced when the mobile communication section, which is a cellular phone function section, receives an incoming call from the base station. Here, various reductions in power supply related to reception can be assumed. For example, one method is to stop the power supply to the tuner section and the other is to change the 13 segment broadcast reception to 1 segment broadcast reception.

Further, in the information processing apparatus according to the present invention described above, the function of selecting a program is remarkably improved by acquiring EPG information, which is electronic program information (EPG), and maximizing it. However, the acquisition of the EPG information is performed using a tuner unit or a mobile communication unit. Such information should be available at an optimal timing in consideration of power consumption. If the tuner section is not used here and the mobile communication section, which is a cellular phone function section, does not communicate with the base station, it is assumed that the acquisition of EPG information will be performed automatically. In this way, the EPG information can be utilized as much as possible without degrading the inherent receiving function or calling function.

(Configuration)

The information processing apparatus 1 which is the first embodiment of the information processing apparatus according to the present invention has a key input unit 17 which is an operation unit first in FIG. 1 and a control unit 16 connected to this and performing overall operations.

The information processing apparatus 1 is a configuration for a mobile telephone which is a mobile communication unit, and the antenna 11 is connected to the RF circuit 14 including the down converter and the up converter through the amplifiers 12 and 13 so that the input / output is a baseband.

Further, the information processing apparatus 1 is a configuration for a TV receiver such as digital terrestrial broadcasting, which is included in a portion surrounded by a solid line, and is provided with a tuner section 24 connected to the antenna 11 described above, and this output is supplied. MPEG decoder 25 for decoding MPEG information, EPG acquisition unit 32 connected to tuner unit 24 to acquire EPG information, output of this MPEG decoder 25 and baseband circuit 15 described above. Has a switching unit 22 to which the image output of the controller is connected and a display 18 to which the output of the switching unit is selectively supplied. The display 18 is connected to a brightness setting unit 31 for setting the brightness of the display 18 under the control of the control unit 16. In addition, the information processing apparatus 1 has a switching section 23 to which the audio output of the baseband circuit 15 and the audio output of the MPEG decoder 25 described above are supplied and selectively output this to the earphone terminal 21 or the like. have.

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 respectively shown, and the power source 1 is a power source that can be turned on and off by the user of the switch 27, and is connected to the battery 28 through the switch 27. It is. The power supply 2 supplies power to the tuner portion 24 and the MPEG decoder 25 used only for watching TV, and the power supply 1 supplies power to portions other than the power supply 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. Doing.

(action)

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 shown in FIG. 1, it is assumed that the switch 26 is activated in the off state. Next, when the user presses an independent dedicated button or the like on the key input unit 17 to watch TV, it is considered that there has been a TV viewing request (S11), and the switch 26 is turned on so that the tuner unit 24 and the MPEG decoder are turned on. Power is supplied to 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 to generate an electronic program table (hereinafter referred to as EPG). Display on the display unit 18 (S13).

Here, SI (Service Information) is program arrangement information and various kinds of information defined for convenience of program selection. The content defined by the Ministry of Internal Affairs and Communications is defined in the ARIB standard. In addition to the extended part of the ARIB standard reader, PSI information of MPEG-2 is also included. In addition, PSI (Program Specific Information) is program specific information and information necessary for selecting a required program, and consists of four tables: PAT, PMT, NIT, and CAT. It is regulated by MPEG-2 system standard, general affairs decree.

If there is a selection of a program to be viewed from the user according to the EPG information displayed next (S14), the tuner unit 24 is controlled according to the SI / PSI information to tune the desired channel (S15). On the other hand, if there is no program selection, the previous viewing program (channel) is tuned (S26). In addition, if information for tuning the previous viewing program is lost at this time or the user cannot tune in the previous viewing program (channel) due to the user not turning on the power for a long time or moving to another broadcasting area, etc. It is assumed that 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 at the same time, the switching circuit 23 is switched so as to output the TV audio to the earphones to output the audio (S16).

If there is no incoming call (S17), the process returns to step S26 and continues to provide the program currently being viewed. On the other hand, when there is an incoming call, the switching circuit 22 is switched to notify the user that an incoming call has occurred, and an image display indicating that an incoming call has been made is performed (S18).

The image display displaying the incoming call may be duplicated on the TV screen, or the TV screen may be erased to display only the incoming screen. The incoming display screen may be generated by the baseband circuit 15 or may be generated by the controller 16 or a peripheral circuit.

Next, the switch 26 is turned off (S19) to stop the power supply to the tuner unit 24 and the decode circuit 25 such as video and audio. As a result, power is supplied from the power supply unit only to the cellular phone function, which is a mobile communication unit, so that even when the capacity of the battery 28 is insufficient, it is possible to make a reliable call.

Next, the call waiting timer is reset (S20). This call waiting timer may be implemented by a program of the controller 16 or may be performed using a dedicated timer circuit (not shown).

When the call is started (S21), the call is made while the power supply to the tuner unit 24 is stopped until the call is finished (S24), and when the call is finished, the switch 26 is turned on again to receive broadcast. It resumes (S25).

On the other hand, if the call is not started (S21) and the timer has elapsed for a predetermined period (S22) or the call is disconnected (S23), the switch 26 is turned on again and broadcast reception is resumed (S25). If the timer has not elapsed (S22) and the incoming call is not disconnected (S23), it is monitored in step S21 whether the call is made.

As described above, power supply to the broadcast reception function can be stopped in response to a call from the mobile communication unit, thereby reducing power consumption, so that a reliable call can be made even if the power capacity of the battery 28 is not sufficient.

If there is an incoming call during viewing of the program in step S18, when the incoming call screen is displayed under the control of the control unit 16, the tuner unit 24 and the MPEG decode circuit are confirmed after confirming an operation such as pressing a call button by the user. It is also appropriate to stop the power supply to (25) or the like.

As described above, the following method is suitable in addition to stopping the power supply to the tuner unit 24, the MPEG decode circuit 25 and the like in order to reduce power consumption. That is, it is suitable to change the processing from the decoding process of the high quality 13 segment broadcast in which the tuner part 24 consumes much power at the timing of step S19 to the decoding process of 1 segment broadcast with low power consumption. In step S25, the processing returns from the one-segment decoding process to the 13-segment decoding process.

It is also suitable not to immediately change from 13 segments to 1 segment in step S19, but to change only when an operation is proposed and agreed to the user by displaying the change on the display 18. FIG.

In addition, although the display 18 can obtain a high quality image of a TV broadcast by setting a high brightness, it is also suitable to reduce the power consumption by lowering the brightness of the display 18 in step S18 because the power consumption becomes large. In this case, the luminance of the display 18 is changed by the luminance setting unit 31 according to the control signal of the controller 16. Similarly, it is also suitable to propose a change in brightness of the display 18 to the display 18, and then change it after obtaining an operation from an agreed user.

As described above, when there is an incoming call of the cellular phone, processing such as stopping the power supply for the broadcast reception function can be performed for reliable call processing even if the battery capacity is not sufficient.

(Different behavior)

In the flowchart shown in FIG. 3, the operation modification example of the other information processing apparatus 1 is shown. That is, the process from FIG. 3 to step S18 is the same as that shown in the flowchart of FIG. In the flowchart shown in Fig. 2, after the incoming call is displayed in step 18, the switch 26 is immediately turned off to stop supplying power to the broadcast reception process. The telephone wait timer by the circuit or the like is reset (S31). When the call is started (S32), the switch 26 is turned off to stop the power supply to the broadcast reception process (S35). If the call is not made (S32) and the incoming call is cut off (S34) or the incoming call is not cut off (S33), the timer returns to step S26 again to continue receiving the broadcast (S26).

After the switch 26 is turned off (S35) and the call ends (S36), the switch 26 is turned on again to resume broadcast reception (S26).

In the above procedure, the power consumption can be reduced by stopping the power supply to the broadcast reception function according to the incoming call, so that a reliable call can be made even if the power capacity of the battery 28 is not sufficient.

Second Embodiment of Information Processing Apparatus According to the Present Invention

The second embodiment of the information processing apparatus according to the present invention shows that the broadcast receiver automatically acquires EPG information of a broadcast signal when the broadcast receiver does not receive and the mobile communication unit does not talk. 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 flow charts showing another example of the acquisition processing of EPG information in the information processing apparatus according to the present invention. to be.

(substance)

When acquiring broadcast signal SI / PSI information necessary for channel selection or EPG display, there is a limit in the transmission rate of SI / PSI information, so a considerable time may be required after the acquisition starts. For example, in the ARIB standard, operation regulations, etc., the transmission period of SI / PSI information is long, and there may be three to six minutes.

That is, after the user performs an operation for watching TV, power is supplied to a circuit used only for receiving a broadcast such as the tuner unit 24, the decoder circuit 25 such as video and audio, and then the SI / PSI information in the broadcast signal. If the value is obtained, the EPG cannot be presented for a few minutes as the worst value, and because there is no EPG, the viewer cannot operate the program selection or obtain the information for tuning, and thus the TV display can be performed. You can also think of no. This problem is dealt with in the second embodiment as follows.

First, part or all of the SI / PSI information received during previous TV viewing is stored in a storage area such as the controller 16. The SI / PSI information includes additional information such as information essential for tuning (for example, frequency information of each channel) and the name of a program broadcast on each channel. As for the storage of the additional information, the nonvolatile memory of the information processing apparatus is used. It should be stored according to the amount of available memory. In addition, the nonvolatile memory means that the viewer does not turn off even when the power switch 27 is turned off. In addition to the memory that the memory does not turn off even when power is not provided, such as an EEPROM, power that cannot be turned off by the power switch 27 is provided. Memory may be present.

In general, since the information (e.g., frequency information of each channel, etc.) essential for tuning is not changed so much, the viewer performs operations for watching TV so that the decode circuit 25 such as the tuner unit 24 and the video and audio 25 can be used. After the power is supplied to a circuit used only for receiving broadcasts, it is thought that tuning can be performed using SI / PSI information received during previous TV viewing.

However, the name of a program broadcast on each channel is often updated every day, and when the power-off time is long (days), it may not be appropriate as data for EPG display.

Next, the information processing apparatus according to the present invention is premised on being portable and movable. SI / PSI information varies from region to region, especially in terrestrial digital broadcasting. That is, for example, when a user who has normally used the device in the Kanto region of Japan moves to the Kansai region of Japan, the SI / PSI information becomes completely different, and after the movement, the user can select the previous SI / PSI information. none. In this case, there is a problem that it is necessary to acquire the SI / PSI information of the region again after moving, and it takes time to acquire it again.

Therefore, in the second embodiment, the EPG information is automatically acquired when neither the tuner unit which is a TV reception function nor the mobile communication unit which is a mobile phone function is operated.

In addition, although the block diagram of FIG. 4 is basically the same as the block diagram of FIG. 1, the control part 1 memorize | stores the EPG acquisition control program described by the following flowchart, and implements the procedure mentioned later. In addition, the power switch 29 is newly provided to indicate that the MEPG decoder 25 is independently controlled.

(action)

2nd Embodiment is demonstrated using the flowchart shown in FIG. This flow chart is processed when the switches 26 and 29 are off, such as when the cellular phone is waiting or when the cellular phone is called.

First, when the presence or absence of the TV is detected and the user is not watching the TV (S41), the timer is reset (S42). This timer may be realized by a program of the controller 16 or may have a dedicated timer circuit (not shown). Next, when a predetermined time has elapsed by checking the count value of the timer (S43), the switch 26 is turned on (S44) and power is supplied to a circuit block used only for watching TV at least, such as the tuner unit 24. Start to supply power to a circuit block used for extracting at least SI / PSI information from a broadcast signal. In addition, since no TV display is performed, the switch 29 for supplying power to a decoding circuit such as video and audio remains off. The EPG acquisition unit 32 then extracts SI / PSI information from the broadcast signal (S45).

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

The determination of step S46 may be a method of extracting while determining whether all SI / PSI information has been updated, or may be ended by extracting a predetermined time since it is repeatedly extracted by a timer.

In addition, it is also possible to display what is being acquired on the display 18 at the time of acquiring SI / PSI information, that is, EPG information in step S45. In addition, when the acquisition is completed, it may be displayed that the EPG information has been acquired.

As described above, the EPG information may be obtained from the broadcast signal using the tuner unit 24 or the like, but the Internet via the base station 41 through the RF circuit 14 or the baseband circuit 15, which is a mobile communication unit, may be obtained. It is also good to acquire via a back. In this case, it is appropriate to supply power only to the RF circuit 14 or the baseband circuit 15 without supplying power to the tuner unit 24 or the like when acquiring the EPG information.

(Different behavior)

In the case of the flowchart shown in FIG. 6, switching of the base station is detected and EPG information is acquired as a trigger of this.

First, when the presence or absence of the TV is detected and the user is not watching the TV (S41), the timer is reset (S42). This counter may be implemented by a program of the controller 16 or may have a dedicated counter circuit.

 Next, it is determined whether or not switching of the mobile communication unit base station of the information processing apparatus 1 has occurred (S51). When it occurs, the count value is increased (S52). Next, if the count value of the counter is equal to or more than a predetermined number (S43), the switch 26 is turned on (S44), and power supply to a circuit block used only for watching TV at least, such as the tuner unit 24, is started. Power supply is started to the circuit block used to extract SI / PSI information from the broadcast signal. In addition, since no TV display is performed, the switch 29 for supplying power to a decode circuit such as video and audio remains off. The EPG acquisition unit 32 then extracts SI / PSI information from the broadcast signal (S45).

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

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

In the case of the flowchart shown in Fig. 8, the same process as the flowchart shown in Fig. 6 is shown. When the duplication of the base station is detected in step S61, the flow proceeds to step S43. Other than that is the same as that of the flowchart of FIG.

As described above, in the information processing apparatus according to the present invention, the tuner unit automatically acquires the EPG information during the period when the mobile communication unit is not receiving the broadcast signal and the mobile communication unit is not in the call. Since the latest EPG information can be prepared without impairing the function, it is possible to provide an information processing apparatus and an information processing method that perform the maximum function among given power resources.

(Other Embodiments)

In some cases, depending on the region, assuming that the user is moving by electric train, some railway companies may be prohibited from receiving or calling. As a response when the incoming call is prohibited, it is as follows. 9 is a block diagram illustrating another embodiment.

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

As a countermeasure when a call is prohibited, it is as follows. In FIG. 1 or FIG. 4, when a user is watching TV while moving by an electric vehicle and there is an incoming call, an incoming call is received by a pop-up menu display of an on-screen display on the screen without turning off the power (2, 2, 3) immediately. Indicates.

In the pop-up menu display, there are three indications of a call later during a call, missed recording, or moving by a train.If the user selects missed recording, a message indicating that the caller is in a missed recording status is displayed. If the user selects the telephone later during the movement by the electric vehicle, a message indicating that the telephone is to be called later during the tram movement is sent to the call partner.

The message such as the missed recording is generated by the control unit 16 and is stored in advance in a memory not shown. In addition, the control unit 16 also controls a memory (not shown) that stores the message of the other party during the missed recording, and the user makes a request for playback to the control unit 16 through the key input unit 17 after getting off the train. When the message of the other party is stored, the memory is reproduced from the memory (not shown).

The present invention can be realized by those skilled in the art by the various embodiments described above, and it is easy for the person skilled in the art to come up with various modifications of these embodiments, and the present invention can be applied to various embodiments without having the inventive ability. It is possible. Accordingly, the present invention is not intended to be limited to the embodiments described above as it extends to a broad range that does not contradict the disclosed principles and novel features.

That is, in the above embodiment, the case where there is no overlap in the circuit for realizing the function of the cellular phone and the TV function has been described. However, the baseband circuit 15, the decode circuit 25 such as the video and audio, etc. are used as a digital signal processor (DSP). In some cases, both power supplies cannot be converted. However, when each of the functions of the cellular phone and the TV function has a dedicated circuit block, the present invention can be implemented by switching the power supply of the dedicated circuit block.

In addition, in the above description, the mobile phone has a built-in TV reception function as an example, but the same effect can be obtained even when the communication module of the mobile phone is added to a TV in which a digital broadcast reception module is connected to a dedicated TV receiver or a general purpose device. Can be obtained. That is, in a TV in which a communication module of a cellular phone is connected to a dedicated TV receiver, the power supply circuit in the dedicated TV receiver is set to two or more systems as described above, and the dedicated TV is used when communicating using the communication module of the cellular phone. The power consumption of the TV receiver in the receiver is turned off.

In the above-described information processing apparatus according to the present invention, for example, when the tuner unit, which is a reception function of terrestrial digital broadcasting, receives a call from a base station while the mobile communication unit, which is a cellular phone function, is receiving a TV broadcast, it controls to reduce the power supply for reception. Here, the reduction of the power supply related to the reception can be considered in various ways. For example, one method is to stop the power supply to the tuner unit, and it is also possible to change the broadcasting reception of 13 segments to the broadcasting reception of 1 segment. It's another way.

In addition, in the information processing apparatus according to the present invention, acquiring and utilizing Electronic Program Guidance (EPG) information, which is electronic program information, greatly improves the function of program selection. However, the acquisition of the EPG information is performed by using a tuner unit or a mobile communication unit, and should be obtained at an optimum timing in consideration of power consumption. Here, it is specified that the EPG information is automatically acquired when the tuner unit is not used and the mobile communication unit serving as the cellular phone does not communicate with the base station. As a result, the EPG information can be utilized without compromising the original reception function or call function.
