Description

  The present invention relates to a frequency setting device, a frequency setting method, a frequency setting program, and an electronic device for setting a reception frequency when receiving a broadcast radio wave, particularly when the reception frequency needs to be changed with movement. The present invention relates to a frequency setting device, a frequency setting method, a frequency setting program, and an electronic device that can automatically change the setting of a reception frequency in a short time.

  In recent years, portable information terminal devices such as small personal computers and PDAs (Personal Digital Assistance) have been provided with functions for receiving television broadcasting (hereinafter referred to as “TV broadcasting”). . Such an information terminal device can generally be driven by a battery, and a user of the information terminal device can view a television broadcast while away from home or on the move.

  By the way, normally, broadcast stations for television broadcasting include a key station and a relay station. The key station is a station serving as a base point for sending out a broadcast program, and the relay station is a station that sends out a broadcast program of the key station to an area where radio waves do not reach from the key station. The key station and the relay station have exactly the same broadcast programs and their time zones, but have different frequencies of radio waves to be transmitted.

  Therefore, in order to watch a television broadcast while going out or moving using the above-described portable information terminal device, the user needs to change the frequency received by the portable information terminal device according to the location. However, it is very inconvenient to search for a receivable frequency by interrupting viewing and manually changing the reception setting every time video or audio is disturbed.

  Therefore, the reception frequency is set based on the information that associates the region with the frequency that can be received in the region, and the position information of the portable information terminal device obtained by using GPS (Global Positioning System) or a cellular phone. A technique of automatically changing according to a place has been devised (see, for example, Patent Documents 1 and 2).

  However, the intensity of radio waves such as television broadcasting changes depending on external factors such as weather conditions, time zones, and environments. For this reason, in a place where a plurality of frequencies can be received (for example, a boundary between an area covered by a key station and an area covered by a relay station), the optimal frequency for reception varies from moment to moment.

  In general, when a channel is set by a television broadcast receiving device, there is a method of using an auto scan function in addition to setting a frequency based on a region. The auto scan function is a function of automatically searching for a channel that can be received at that time by receiving radio waves while continuously changing the frequency. When this auto-scan function is used, the optimum frequency can be searched each time, so that the optimum frequency can be set even in a place where a plurality of frequencies can be received.

  When changing the reception frequency setting while watching TV broadcast, if it takes a long time to change, it will take longer time to stop watching TV broadcast and miss important scenes or important information will not be obtained This will cause discomfort for the user.

  Therefore, how to automatically change the setting of the reception frequency in a short time when the change of the reception frequency becomes necessary with movement is an extremely important issue.

And it becomes possible to narrow down only to the frequency of the area of the moving destination, and there is an effect that the setting of the reception frequency can be changed in a shorter time.

  In addition, according to the present invention, a selection as to whether or not to execute a process related to the setting of the reception frequency is accepted, and the process is executed only when a selection to execute the process related to the setting of the reception frequency is accepted. Since it is configured, when it is not necessary to automatically change the reception frequency, such as when watching a broadcast without moving, the process is stopped, and the power consumption due to operation of the apparatus can be suppressed. .

  Embodiments of a frequency setting device, a frequency setting method, a frequency setting program, and an electronic device according to the present invention will be described below in detail with reference to the drawings. In this embodiment, the case where the present invention is applied to an information terminal device having a function of receiving an analog television broadcast (hereinafter referred to as “analog broadcast”) will be described. However, the present invention is limited by this embodiment. Is not to be done.

  First, the concept of the information terminal device according to the present embodiment will be described. FIG. 1 is a diagram for explaining the concept of the information terminal device according to the present embodiment.

  A key station A shown in the figure is a television station serving as a base point of analog broadcasting, and relay stations A1 and A2 are relay stations that relay analog broadcasting by the key station A. These stations transmit broadcast radio waves of different frequencies that propagate the same content broadcast, and cover the broadcast areas 10, 20, and 30 shown in FIG.

  The key station B shown in the figure is a television station of the same series as the key station A. The key station B transmits a broadcast radio wave having a frequency different from that of the key station A and the relay stations A1 and A2, in which some programs propagate the same analog broadcast as the key station. Covering. The series here refers to a group of stations (affiliated stations) that broadcast the same program depending on the time zone or day of the week, such as a metropolitan area television station and a local television station.

  Here, while the user of the information terminal device 100 according to the present embodiment is watching the broadcast of the key station A using the information terminal device 100, the broadcast area of the relay station A2 is started from the broadcast area 10 of the key station A. Consider the case of moving to 30 or the broadcasting area 40 of the key station B.

  In the information terminal device 100, information (hereinafter referred to as “key station group information”) in which the broadcast radio wave frequencies of stations that broadcast the same content are grouped together as the same key station group is stored for each key station. In addition, information (hereinafter referred to as “affiliated station group information”) in which the frequencies of broadcast radio waves of the key stations of the same series are grouped as the same affiliated station group is stored for each affiliated station. Here, in the information terminal device 100, the frequency of the broadcast radio wave of the key station A, the frequency of the broadcast radio wave of the relay station A1, and the frequency of the broadcast radio wave of the relay station A2 are stored as the same key station group. The frequency of the broadcast radio wave of the key station A and the frequency of the broadcast radio wave of the key station B are stored as the same affiliated station group.

  First, consider a case where the user has moved from the broadcast area 10 to the broadcast area 30 (see (1) in the figure). The information terminal device 100 constantly monitors whether the sound data of the broadcast radio waves of the key station A is stereo sound or monaural sound, and confirms that the sound data is monaural sound continuously for a predetermined time. It is determined that the broadcast radio wave of A is weakened, and the frequency of other stations belonging to the same key station group as the frequency of the station being received is obtained by referring to the key station group information. Here, the information terminal device 100 acquires the frequencies of the relay station A1 and the relay station A2.

  Then, the information terminal device 100 confirms whether the received broadcast radio wave audio data is stereo audio or monaural audio while setting the acquired frequencies one by one as the reception frequency, and is stereo audio. If it is confirmed, the frequency set at that time is fixed as the reception frequency. Here, since the information terminal device 100 is moved into the broadcast area 30 of the relay station A2, when the frequency of the relay station A2 is set, the information terminal device 100 confirms that the audio data is stereo sound and receives the frequency. Fix as frequency.

  Next, consider a case where the user has moved from the broadcast area 10 to the broadcast area 40 (see (2) in the figure). When the information terminal apparatus 100 determines that the broadcast radio wave of the key station A is weak, as in the case of moving to the broadcast area 30, the information terminal apparatus 100 refers to the key station group information and uses the same key as the frequency of the station being received. Get the frequencies of other stations belonging to the station group. Also here, the information terminal device 100 acquires the frequencies of the relay station A1 and the relay station A2.

  And the information terminal device 100 confirms whether the audio | voice data of the received broadcast radio wave is a stereo audio | voice or a monaural audio | voice, setting the acquired frequency to a receiving frequency one by one. Here, since the information terminal device 100 has been moved into the broadcast area 40 and is neither in the broadcast area 10 of the relay station A1 nor in the broadcast area 20 of the relay station A2, the audio data is stereo sound. I can't confirm that.

  Therefore, the information terminal device 100 determines that it is impossible to receive the same content broadcast, and refers to the affiliated station group information to determine another key belonging to the affiliated station group that is the same as the frequency of the receiving station. Get station frequency. Here, the information terminal device 100 acquires the frequency of the key station B.

  Then, the information terminal device 100 sets the frequency of the key station B as the reception frequency, and confirms whether the received broadcast radio sound data is stereo sound or monaural sound. Here, since the information terminal device 100 has moved into the broadcast area 40 of the key station B, the information terminal device 100 confirms that the sound data is stereo sound and fixes the frequency as the reception frequency.

  As described above, the information terminal device 100 according to the present embodiment propagates the same content broadcast and transmits a plurality of broadcast waves having different frequencies when broadcast waves having different frequencies are transmitted from a plurality of broadcast stations. Is stored as key station group information, and it is monitored whether the audio data of the broadcast radio wave is stereo audio or monaural audio during reception of the broadcast radio wave. The main feature is that, when it is confirmed, the reception frequency is set to the frequency of another broadcast radio wave belonging to the same group as the broadcast radio wave being received based on the key station group information.

  Furthermore, the information terminal device 100 according to the present embodiment stores information related to a group of a plurality of broadcast radio waves that are propagated in the same part of the content and have different frequencies as affiliated station group information. If there is no broadcast radio wave that satisfies the specified quality among broadcast radio waves belonging to the group stored as information, other broadcasts belonging to the same affiliate station group as the received broadcast radio wave based on the stored affiliate group information The main feature is that the reception frequency is set to the frequency of the radio wave.

  That is, the information terminal device 100 according to the present embodiment not only sets the reception frequency that can be automatically received when it becomes necessary to change the setting of the reception frequency with movement, but also sets the reception frequency. A function capable of shortening the time is provided.

  Next, the configuration of the information terminal device according to the present embodiment will be described.

FIG. 3 is a diagram illustrating an example of key station group information. As shown in the figure, the key station group information is information configured by associating the channel of the key station with the channels of a plurality of relay stations that relay the broadcast of the key station. The channel here is identification information for uniquely identifying a station, and each channel is assigned a unique frequency. Specifically, as shown in the figure, the channel is represented by a channel-specific number such as “4ch” or “53ch”.

  The channels belonging to the key station group information are further classified for each broadcast area. Here, the broadcast area is an area where each station covers the broadcast, which is determined based on the reach of the broadcast radio wave. Specifically, the broadcast area is represented by an identifier unique to each broadcast area, such as “Code42” and “Code033”. In the figure, “Code 040/037, Code 042/046” indicates that broadcast areas “Code 040”, “Code 037”, “Code 042”, and “Code 046” are covered by the same station. Yes.

  For example, the key station group 50 shown in the figure is a group in which stations having the same contents as the broadcast of the key station “4ch” are grouped, and eight types of channels (4ch, 16ch, 35ch, 36ch, 42ch, 51ch) are collected. , 53ch, 54ch) are classified into 19 broadcast areas (Code 031 to 049).

  The affiliated station group table 142 is a table that stores affiliated station group information that summarizes the frequencies of broadcast radio waves of the same affiliated key stations for each affiliated station. FIG. 4 is a diagram illustrating an example of affiliated station group information. As shown in the figure, the affiliated station group information is information in which the channels of the same affiliated key stations are grouped into the same affiliated station group, and the channels belonging to the affiliated station group information are further classified for each broadcast area. Yes.

  For example, the key station group 60 shown in the figure is a group in which key stations of the same series as the broadcasting of the key station “4ch” are grouped, and five types of channels (4ch, 39ch, 51ch, 52ch, 54ch) are 5 The broadcast areas are classified into code areas (Code 042, 135, 254, 357, 495).

  The control unit 150 is a control unit that performs overall control of the information terminal device 100, and includes a radio wave quality monitoring unit 151, a frequency setting unit 152, and a process selection receiving unit 153 as those related to the present invention. Although not shown here, the control unit 150 demodulates the broadcast radio wave received by the TV tuner 110 and outputs a television broadcast image obtained thereby to the display unit 120. A functional part is also provided.

  The radio wave quality monitoring unit 151 is a processing unit that monitors whether the audio data of the broadcast radio wave is stereo audio or monaural audio during reception of the broadcast radio wave. Specifically, the radio wave quality monitoring unit 151 always inputs audio data output from the TV tuner 110 and confirms whether the audio data is stereo audio or monaural audio. The result is notified to a frequency setting unit 152 described later.

  The frequency setting unit 152 is a processing unit that automatically sets the reception frequency. Specifically, when the confirmation result of the audio data notified from the radio wave quality monitoring unit 151 is monophonic for a predetermined time, the frequency setting unit 152 uses the processing selection receiving unit 153 described later to use It is confirmed whether or not the selection to move the received frequency is accepted from the person. Then, the frequency setting unit 152 performs the process related to the setting of the reception frequency described below only when the selection for moving the reception frequency is accepted.

  In this case, the frequency setting unit 152 determines that the broadcast radio wave being received is weak, and first displays a frequency change notification dialog on the display unit 120 to notify the user that the setting of the reception frequency is to be changed. To do. FIG. 6 is a diagram illustrating an example of a frequency change notification dialog.

  Subsequently, the frequency setting unit 152 refers to the key station group table 141 and belongs to the same key station group as the channel of the broadcast radio wave being received, and the broadcast area is set by the process selection receiving unit 153 described later. Get the frequency that is the same as the destination area.

  Then, the frequency setting unit 152 sets the acquired frequency as the reception frequency in the TV tuner 110, and then confirms the confirmation result of the audio data notified from the radio wave quality monitoring unit 151, and the audio data is stereo audio. If this is confirmed, the reception frequency set in the TV tuner 110 at that time is fixed.

  On the other hand, if it is confirmed that the audio data is monaural audio after setting the reception frequency, the frequency setting unit 152 should continuously receive the same broadcast at the frequency in the area set as the destination. Referring to the key station group table 141 again, the frequency of another channel belonging to the same key station group as the channel of the broadcast radio wave being received is acquired.

  Then, the frequency setting unit 152 confirms the confirmation result of the audio data notified from the radio wave quality monitoring unit 151 while setting the acquired frequencies one by one as the reception frequency in the TV tuner 110, and the audio data is stereo. When it is confirmed that the voice is received, the reception frequency set in the TV tuner 110 at that time is fixed.

  On the other hand, if it is not confirmed that the audio data is stereo audio, it is determined that it is impossible to receive the same content broadcast, and first the user is notified that the broadcast station is to be changed. The broadcast station change dialog for displaying is displayed on the display unit 120. FIG. 7 is a diagram illustrating an example of a broadcast station change dialog.

  Subsequently, the frequency setting unit 152 refers to the affiliated station group table 142 and acquires the frequency of the channel of another key station belonging to the same affiliated station group as the channel of the broadcast radio wave being received.

  Then, the frequency setting unit 152 confirms the confirmation result of the audio data notified from the radio wave quality monitoring unit 151 while setting the acquired frequencies one by one as the reception frequency in the TV tuner 110, and the audio data is stereo. When it is confirmed that the voice is received, the reception frequency set in the TV tuner 110 at that time is fixed.

  Furthermore, when the reception frequency is set (changed) by any one of the above-described procedures, the frequency setting unit 152 sets another change in the same broadcasting area as the channel set here in the key station group table 141. Each channel is also set as a reception frequency. Thereby, when the reception frequency of one channel is set, all the channels that can be received at that place can be received.

  The process selection receiving unit 153 is a processing unit that receives a selection as to whether or not to execute the process related to the setting of the reception frequency by the frequency setting unit 152. Specifically, the process selection accepting unit 153 displays a movement correspondence setting dialog on the display unit 120, and determines whether or not to perform movement correspondence of the reception frequency by the radio wave quality monitoring unit 151 and the frequency setting unit 152 from the user. And the input of the area of the movement source and the area of the movement destination when the movement correspondence is performed. The source area and the destination area received here correspond to broadcast areas, respectively.

  FIG. 5 is a diagram illustrating an example of a movement setting dialog. The figure shows a case where the user selects to perform movement and inputs “in Tokyo” as the destination area and “Hachioji” as the destination area.

  The process selection accepting unit 153 receives the selection of whether or not to perform movement correspondence of the reception frequency and the input of the movement source area and the movement destination area in the case of performing movement correspondence as the movement setting information. For example, it is stored in the storage unit 140 or the like. The process selection receiving unit 153 overwrites and updates the movement setting information every time it is input by the user.

  Next, a processing procedure of the information terminal device 100 according to the present embodiment will be described. 8 and 9 are flowcharts illustrating the processing procedure of the information terminal device 100 according to the present embodiment. As shown in the figure, when the information terminal device 100 is instructed by the user to output a television broadcast, first, the process selection accepting unit 153 displays a movement correspondence setting dialog on the display unit 120 (step S120). S101), ON / OFF corresponding to movement, and input of movement source and movement destination are accepted (step S102).

  Subsequently, the television function unit of the control unit 150 sets the frequency of the area designated as the movement source to the tuner 110 as a reception frequency (step S103), and starts the video output of the television broadcast received by the TV tuner 110. (Step S104).

  Thereafter, the frequency setting unit 152 confirms whether or not the television broadcast is a stereo audio program. Here, when the television broadcast is not a stereo audio program, the frequency setting unit 152 continues the same confirmation until the stereo audio television broadcast starts (step S105, No), and the television broadcast is a stereo audio program. When it is confirmed that the program is a program (step S105, Yes), it is confirmed whether or not the audio data output from the TV tuner 110 is stereo audio.

  Here, while confirming that the sound data is stereo sound (Yes in step S106), the frequency setting unit 152 continues the same confirmation, and the sound data is not stereo sound (is monaural sound). (Step S106, No), and after confirming that the monaural sound has continued for a predetermined time (step S107, Yes and No), it is determined that the frequency designated as the movement source cannot be received. (Step S108).

  Then, the frequency setting unit 152 confirms ON / OFF corresponding to movement, and if the movement correspondence is OFF (No in step S109), the frequency setting unit 152 sets the reception frequency without performing the following series of processes. This process is terminated. On the other hand, when the movement correspondence is ON (step S109, Yes), the frequency setting unit 152 displays the frequency change notification dialog on the display unit 120 (step S110), and then whether or not the movement destination is set. To check.

  If the destination has been set (step S111, Yes), the frequency setting unit 152 sets the frequency of the area specified as the destination as the reception frequency (step S112), and further, step Returning to S105, the processing is continued. On the other hand, if the destination has not been set (step S111, No), the frequency of other broadcast radio waves belonging to the same key station group as the frequency of the received broadcast radio wave is referred to the key station group table 141. Is acquired (step S113), and the frequency of the broadcast radio wave in which the audio data can be received as stereo audio is detected.

  Here, when the frequency of the broadcast radio wave that can be received by the audio data as stereo sound is detected (step S114, Yes), the frequency setting unit 152 sets the frequency as the reception frequency in the TV tuner 110 (step S115). Further, the process returns to step S105 to continue the processing. On the other hand, when the frequency of the broadcast radio wave that can be received as stereo sound is not detected in the audio data (No in step S114), the frequency setting unit 152 displays that the current location is not the designated area. Displayed on the unit 120 (step S116), and by referring to the affiliated station group table 142, obtains the frequency of another broadcast radio wave belonging to the same affiliated station group as the frequency of the broadcast radio wave being received (step S117). Then, the frequency of the broadcast radio wave that can be received by the audio data as stereo sound is detected.

  Here, when the frequency of the broadcast radio wave that can be received by the stereo data as audio data can be detected (step S118, Yes), the frequency setting unit 152 displays a broadcast station change dialog on the display unit 120 (step S119). The frequency is set in the TV tuner 110 as a reception frequency (step S120), and the process returns to step S105 to continue the process. On the other hand, when the frequency of the broadcast radio wave that can be received by the stereo data as audio data cannot be detected (No in step S118), the frequency setting unit 152 informs the display unit 120 that the video output of the television broadcast cannot be continued. Display (step S121), and a series of processing relating to the setting of the reception frequency is terminated.

  As described above, in the present embodiment, when broadcast radio waves having different frequencies are transmitted from a plurality of broadcast stations, the same contents are propagated and a plurality of broadcast radio waves having different frequencies are related. Information is stored in the key station group table 141 as key station group information, and the radio wave quality monitoring unit 151 monitors the quality of the broadcast radio wave during reception of the broadcast radio wave, and the monitored quality does not satisfy the predetermined quality. In this case, based on the key station group information stored in the key station group table 141, the frequency setting unit 152 sets the frequency of another broadcast radio wave belonging to the same key station group as the received broadcast radio wave as the reception frequency. Therefore, it is possible to narrow down the frequency for determining whether or not reception is possible to only the frequency of the broadcast radio wave that propagates the broadcast of the same content. Of when a change is needed, it is possible to change the setting of the automatic reception frequency in a short time.

  Further, in this embodiment, information related to a group of a plurality of broadcast radio waves that propagate the same part of the content and have different frequencies is stored in the affiliated station group table 142 as affiliated station group information, and the frequency setting unit When there is no broadcast radio wave satisfying a predetermined quality among broadcast radio waves belonging to the group stored as the key station group information 152, based on the affiliated station group information stored in the affiliated station group table 142, Since the frequency of other broadcast radio waves that belong to the same affiliate group as the broadcast radio wave is set as the reception frequency, even if the frequency that propagates the broadcast of exactly the same content could not be set as the reception frequency, Depending on the time zone and day of the week, the frequency of a broadcasting station that may be broadcasting the same program can be set as the reception frequency.

  Also, in this embodiment, broadcast radio waves belonging to the group stored in the key station group table 141 as key station group information are stored in association with broadcast areas, respectively, and when the frequency setting unit 152 sets the reception frequency, Broadcast radio wave reception frequency that propagates other contents of broadcast is set to the same frequency as the broadcast radio wave area that propagates other contents and that corresponds to the set reception frequency. Since the setting is made, the setting of each reception frequency can be simultaneously changed for broadcast stations other than the broadcast station that was actually viewed by the user when the reception frequency was set.

  In the present embodiment, the group stored in the key station group table 141 as key station group information is composed of broadcast radio waves associated with the destination area and broadcast radio waves associated with the source area. The radio wave quality monitoring unit 151 monitors the quality of the broadcast radio wave during reception of the broadcast radio wave associated with the movement source area. If the monitored quality does not satisfy the predetermined quality, the frequency setting is performed. Based on the information stored in the key station group table 141 as the key station group information, the unit 152 sets the reception frequency to the frequency of the broadcast radio wave associated with the destination area. If the destination area is set, it is possible to narrow down the frequency for determining whether or not reception is possible to only the frequency of the movement source area and the frequency of the movement destination area. It is possible to change the setting of reception frequency in a shorter time.

  Further, in this embodiment, only when the process selection receiving unit 153 receives a selection as to whether or not to execute the process related to the setting of the reception frequency and receives a selection to execute the process related to the setting of the reception frequency, Since the frequency setting unit 152 executes the process, when it is not necessary to automatically change the reception frequency, such as when viewing a broadcast without moving, the process is stopped and power consumption due to operation of the apparatus is stopped. Can be suppressed.

  In this embodiment, the radio wave quality monitoring unit 151 monitors whether the audio data propagated by the broadcast radio wave is stereo audio or monaural audio, and based on the monitoring result, the frequency setting unit 152 Because it determines whether or not the quality of the broadcast radio wave satisfies the specified quality, if the received broadcast radio wave becomes weak, the audio data of the stereo broadcast deteriorates to become monaural audio. Thus, the reception frequency can be automatically switched.

  Although the embodiments of the present invention have been described so far, the present invention may be implemented in various different embodiments other than the above-described embodiments.

  For example, when the present invention is applied to an information terminal device having a function of receiving a digital television broadcast, the TV tuner 110 receives a broadcast wave of the digital television broadcast, and the radio wave quality monitoring unit 151 is received from the TV tuner 110. Check if data (video data, audio data, etc.) is being output.

  When the frequency setting unit 152 confirms that the data has not been output for a predetermined time, the frequency setting unit 152 determines that the broadcast radio wave being received is weakened, and the frequency of the reception frequency described so far is determined. Performs processing related to settings.

  For example, when the present invention is applied to an information terminal device having a GPS function, the position of the own device can be specified based on the position information acquired by the GPS function. No need to accept any other areas or destination areas. As a result, it is possible to save the setting work required in advance when the user views the television broadcast on the information terminal device.

  In the present embodiment, the information terminal device 100 to which the present invention is applied has been described. However, by realizing the configuration of the information terminal device 100 by software, a frequency setting program having the same function can be obtained. . A computer that executes the frequency setting program will be described.

  FIG. 10 is a functional block diagram illustrating the configuration of a computer that executes a frequency setting program according to the present embodiment. As shown in the figure, the computer 200 includes a RAM (Random Access Memory) 210, a CPU (Central Processing Unit) 220, an HDD (Hard Disk Drive) 230, a LAN (Local Area Network) interface 240, and an input.

  The RAM 210 is a memory that stores a program and a program execution result, and the CPU 220 is a central processing unit that reads the program from the RAM 210 and executes the program.

  The HDD 230 is a disk device that stores programs and data, and the LAN interface 240 is an interface for connecting the computer 200 to other computers via the LAN.

  The input / output interface 250 is an interface for connecting an input device such as a mouse or a keyboard and a display device, and the DVD drive 260 is a device for reading / writing a DVD.

  The frequency setting program 211 executed in the computer 200 is stored in the DVD, read from the DVD by the DVD drive 260, and installed in the computer 200.

  Alternatively, the frequency setting program 211 is stored in a database or the like of another computer system connected via the LAN interface 240, read from these databases, and installed in the computer 200.

  In addition, among the processes described in the present embodiment, all or part of the processes described as being automatically performed can be performed manually, or the processes described as being performed manually can be performed. All or a part can be automatically performed by a known method.

  In addition, the processing procedure, control procedure, specific name, and information including various data and parameters shown in the above-described document and drawings can be arbitrarily changed unless otherwise specified.

  Each component of each illustrated device is functionally conceptual and does not necessarily need to be physically configured as illustrated. In other words, the specific form of distribution / integration of each device is not limited to that shown in the figure, and all or a part thereof may be functionally or physically distributed or arbitrarily distributed in arbitrary units according to various loads or usage conditions. Can be integrated and configured.

  Furthermore, all or a part of each processing function performed in each device may be realized by a CPU and a program that is analyzed and executed by the CPU, or may be realized as hardware by wired logic.

  As described above, the frequency setting device, the frequency setting method, the frequency setting program, and the electronic device according to the present invention are useful for personal computers and PDAs having a function of receiving television broadcasts, and are particularly received as they move. This is suitable when it is necessary to change the reception frequency automatically in a short time when the frequency needs to be changed.

  The present invention relates to a frequency setting program and an electronic device for setting a reception frequency when receiving a broadcast radio wave, and in particular, when a change in the reception frequency is necessary with movement, the reception is automatically performed in a short time. The present invention relates to a frequency setting program and an electronic device that can change a frequency setting.

  In recent years, portable information terminal devices such as small personal computers and PDAs (Personal Digital Assistance) have been provided with functions for receiving television broadcasting (hereinafter referred to as “TV broadcasting”). . Such an information terminal device can generally be driven by a battery, and a user of the information terminal device can view a television broadcast while away from home or on the move.

  By the way, normally, broadcast stations for television broadcasting include a key station and a relay station. The key station is a station serving as a base point for sending out a broadcast program, and the relay station is a station that sends out a broadcast program of the key station to an area where radio waves do not reach from the key station. The key station and the relay station have exactly the same broadcast programs and their time zones, but have different frequencies of radio waves to be transmitted.

  Therefore, in order to watch a television broadcast while going out or moving using the above-described portable information terminal device, the user needs to change the frequency received by the portable information terminal device according to the location. However, it is very inconvenient to search for a receivable frequency by interrupting viewing and manually changing the reception setting every time video or audio is disturbed.

  Therefore, the reception frequency is set based on the information that associates the region with the frequency that can be received in the region, and the position information of the portable information terminal device obtained by using GPS (Global Positioning System) or a cellular phone. A technique of automatically changing according to a place has been devised (see, for example, Patent Documents 1 and 2).

  However, the intensity of radio waves such as television broadcasting changes depending on external factors such as weather conditions, time zones, and environments. For this reason, in a place where a plurality of frequencies can be received (for example, a boundary between an area covered by a key station and an area covered by a relay station), the optimal frequency for reception varies from moment to moment.

  In general, when a channel is set by a television broadcast receiving device, there is a method of using an auto scan function in addition to setting a frequency based on a region. The auto scan function is a function of automatically searching for a channel that can be received at that time by receiving radio waves while continuously changing the frequency. When this auto-scan function is used, the optimum frequency can be searched each time, so that the optimum frequency can be set even in a place where a plurality of frequencies can be received.

JP 2005-175556 A Japanese Patent Laid-Open No. 7-284030

  However, when the auto scan function is used, it is necessary to change the frequency in a wide range, and there is a problem that it takes time to search for the optimum frequency.

  When changing the reception frequency setting while watching TV broadcast, if it takes a long time to change, it will take longer time to stop watching TV broadcast and miss important scenes or important information will not be obtained This will cause discomfort for the user.

  Therefore, how to automatically change the setting of the reception frequency in a short time when the change of the reception frequency becomes necessary with movement is an extremely important issue.

  The present invention has been made to solve the above-described problems caused by the prior art, and automatically changes the setting of the reception frequency in a short time when it is necessary to change the reception frequency along with movement. It is an object of the present invention to provide a frequency setting program and an electronic device that can be used.

  In order to solve the above-described problems and achieve the object, the present invention is a frequency setting program for setting a reception frequency when receiving broadcast radio waves, and broadcast radio waves of different frequencies are transmitted from a plurality of broadcast radio wave transmission devices. A group information storage procedure for storing information related to a plurality of broadcast radio wave groups that propagate the same content broadcast and have different frequencies when transmitted, and the quality of the broadcast radio wave during reception of the broadcast radio wave. Radio wave quality monitoring procedure to be monitored, and when the quality monitored by the radio wave quality monitoring procedure does not satisfy a predetermined quality, based on the information stored by the group information storage procedure, A frequency setting procedure for setting the reception frequency to a frequency of another broadcast radio wave belonging to the same group is executed by a computer.

  In addition, the present invention is an electronic device that receives broadcast radio waves and outputs information related to the broadcast propagated by the broadcast radio waves, where broadcast radio waves of different frequencies are transmitted from a plurality of broadcast radio wave transmission devices In addition, group information storage means for storing information related to a plurality of groups of broadcast radio waves that propagate the same content and have different frequencies, and radio wave quality monitoring that monitors the quality of the broadcast radio waves during reception of the broadcast radio waves And, when the quality monitored by the radio wave quality monitoring unit does not satisfy a predetermined quality, other members belonging to the same group as the broadcast radio wave being received based on the information stored by the group information storage unit Frequency setting means for setting the reception frequency to the frequency of the broadcast radio wave, and the broadcast radio wave received at the frequency set by the frequency setting means, And information output means for outputting such information, characterized by comprising a.

  Further, the present invention, in the above invention, further comprises a secondary group information storage means for storing information related to a group of a plurality of broadcast radio waves that propagate the same part of the broadcast and have different frequencies, When there is no broadcast radio wave satisfying a predetermined quality among broadcast radio waves belonging to the group in which the information is stored by the group information storage unit, the frequency setting unit is stored in the information stored in the secondary group information storage unit. Based on this, the reception frequency is set to the frequency of another broadcast radio wave belonging to the same group as the broadcast radio wave being received.

  Further, the present invention is the above invention, wherein broadcast radio waves belonging to the group for which information is stored by the group information storage means are stored in association with regional information, and the frequency setting means sets the reception frequency. In this case, the reception frequency of the broadcast radio wave that propagates the broadcast of other contents is the broadcast frequency that propagates the other content and that corresponds to the same area as the broadcast radio wave area corresponding to the set reception frequency. It is characterized by setting to the frequency of radio waves.

  Further, the present invention is the above invention, wherein the group in which the information is stored by the group information storage means includes a broadcast radio wave associated with the destination area, a broadcast radio wave associated with the destination area, The radio wave quality monitoring means monitors the quality of the broadcast radio wave during reception of the broadcast radio wave associated with the movement source area, and the frequency setting means is monitored by the radio wave quality monitoring means. If the received quality does not satisfy the predetermined quality, the reception frequency is set to the frequency of the broadcast radio wave associated with the destination area based on the information stored by the group information storage means. It is characterized by.

  In the above invention, the present invention further includes a process selection accepting unit that accepts a selection as to whether or not to execute a process related to setting of a reception frequency by the frequency setting unit, and the frequency setting unit includes the process selection The processing is executed only when a selection to execute the processing related to the setting of the reception frequency is received by the receiving means.

  In the present invention, the radio wave quality monitoring unit monitors whether the audio data propagated by the broadcast radio wave is stereo sound or monaural sound, and the frequency setting unit Based on the result of monitoring by the quality monitoring means, it is determined whether or not the quality of the broadcast radio wave satisfies a predetermined quality.

  According to the present invention, when broadcast radio waves having different frequencies are transmitted from a plurality of broadcast radio wave transmitters, information relating to a group of a plurality of broadcast radio waves having the same contents and having different frequencies is grouped. Store as information, monitor the quality of the broadcast radio wave while receiving the broadcast radio wave, and if the monitored quality does not satisfy the specified quality, the same as the broadcast radio wave being received based on the stored group information Since it is configured to set the reception frequency to the frequency of other broadcast radio waves belonging to the group, it is possible to narrow down the frequency for determining whether or not reception is possible to only the frequency of the broadcast radio wave that propagates the same content broadcast. As a result, when the reception frequency needs to be changed, the reception frequency can be automatically changed in a short time.

  Further, according to the present invention, information related to a group of a plurality of broadcast radio waves that propagate the same part of the broadcast and have different frequencies is stored as the secondary group information, and belongs to the group stored as the group information. When there is no broadcast radio wave that satisfies the specified quality, the reception frequency is set to the frequency of another broadcast radio wave that belongs to the same group as the broadcast radio wave that is being received, based on the stored secondary group information. Broadcasting stations that may broadcast the same program depending on the time of day or day of the week, such as broadcasting of affiliated stations, even if the frequency that propagates exactly the same content broadcast cannot be set as the receiving frequency It is possible to set the frequency to be the reception frequency.

  In addition, according to the present invention, broadcast radio waves belonging to a group stored as group information are stored in association with local information, and when a reception frequency is set, reception of broadcast radio waves that propagate other contents of the broadcast is received. When the reception frequency is set, the frequency is set to the frequency of the broadcast radio wave that propagates other contents and corresponds to the same area of the broadcast radio wave corresponding to the set reception frequency. For broadcast stations other than the broadcast station that was actually viewed by the user, it is possible to simultaneously change the settings of the respective reception frequencies.

  Further, according to the present invention, the group stored as the group information is composed of a broadcast radio wave associated with the destination area and a broadcast radio wave associated with the source area, and the group is stored in the source area. Monitor the quality of the broadcast radio wave during reception of the associated broadcast radio wave, and if the monitored quality does not satisfy the specified quality, respond to the destination area based on the information stored as group information Since the receiving frequency is set to the frequency of the attached broadcast radio wave, if the source area and the destination area are set in advance, the frequency for determining whether or not reception is possible is set to the frequency of the source area. And it becomes possible to narrow down only to the frequency of the area of the moving destination, and there is an effect that the setting of the reception frequency can be changed in a shorter time.

  In addition, according to the present invention, a selection as to whether or not to execute a process related to the setting of the reception frequency is accepted, and the process is executed only when a selection to execute the process related to the setting of the reception frequency is accepted. Since it is configured, when it is not necessary to automatically change the reception frequency, such as when watching a broadcast without moving, the process is stopped, and the power consumption due to operation of the apparatus can be suppressed. .

  Further, according to the present invention, it is monitored whether the audio data propagated by the broadcast radio wave is stereo audio or monaural audio, and the quality of the broadcast radio wave satisfies a predetermined quality based on the monitoring result. Since it is configured to determine whether or not the received broadcast radio wave is weak, the reception frequency is automatically switched using the fact that the audio data of stereo broadcast deteriorates to become monaural sound. There is an effect that can be performed.

  Embodiments of a frequency setting program and an electronic device according to the present invention will be described below in detail with reference to the drawings. In this embodiment, the case where the present invention is applied to an information terminal device having a function of receiving an analog television broadcast (hereinafter referred to as “analog broadcast”) will be described. However, the present invention is limited by this embodiment. Is not to be done.

  First, the concept of the information terminal device according to the present embodiment will be described. FIG. 1 is a diagram for explaining the concept of the information terminal device according to the present embodiment.

  A key station A shown in the figure is a television station serving as a base point of analog broadcasting, and relay stations A1 and A2 are relay stations that relay analog broadcasting by the key station A. These stations transmit broadcast radio waves of different frequencies that propagate the same content broadcast, and cover the broadcast areas 10, 20, and 30 shown in FIG.

  The key station B shown in the figure is a television station of the same series as the key station A. The key station B transmits a broadcast radio wave having a frequency different from that of the key station A and the relay stations A1 and A2, in which some programs propagate the same analog broadcast as the key station. Covering. The series here refers to a group of stations (affiliated stations) that broadcast the same program depending on the time zone or day of the week, such as a metropolitan area television station and a local television station.

  Here, while the user of the information terminal device 100 according to the present embodiment is watching the broadcast of the key station A using the information terminal device 100, the broadcast area of the relay station A2 is started from the broadcast area 10 of the key station A. Consider the case of moving to 30 or the broadcasting area 40 of the key station B.

  In the information terminal device 100, information (hereinafter referred to as “key station group information”) in which the broadcast radio wave frequencies of stations that broadcast the same content are grouped together as the same key station group is stored for each key station. In addition, information (hereinafter referred to as “affiliated station group information”) in which the frequencies of broadcast radio waves of the key stations of the same series are grouped as the same affiliated station group is stored for each affiliated station. Here, in the information terminal device 100, the frequency of the broadcast radio wave of the key station A, the frequency of the broadcast radio wave of the relay station A1, and the frequency of the broadcast radio wave of the relay station A2 are stored as the same key station group. The frequency of the broadcast radio wave of the key station A and the frequency of the broadcast radio wave of the key station B are stored as the same affiliated station group.

  First, consider a case where the user has moved from the broadcast area 10 to the broadcast area 30 (see (1) in the figure). The information terminal device 100 constantly monitors whether the sound data of the broadcast radio waves of the key station A is stereo sound or monaural sound, and confirms that the sound data is monaural sound continuously for a predetermined time. It is determined that the broadcast radio wave of A is weakened, and the frequency of other stations belonging to the same key station group as the frequency of the station being received is obtained by referring to the key station group information. Here, the information terminal device 100 acquires the frequencies of the relay station A1 and the relay station A2.

  Then, the information terminal device 100 confirms whether the received broadcast radio wave audio data is stereo audio or monaural audio while setting the acquired frequencies one by one as the reception frequency, and is stereo audio. If it is confirmed, the frequency set at that time is fixed as the reception frequency. Here, since the information terminal device 100 is moved into the broadcast area 30 of the relay station A2, when the frequency of the relay station A2 is set, the information terminal device 100 confirms that the audio data is stereo sound and receives the frequency. Fix as frequency.

  Next, consider a case where the user has moved from the broadcast area 10 to the broadcast area 40 (see (2) in the figure). When the information terminal apparatus 100 determines that the broadcast radio wave of the key station A is weak, as in the case of moving to the broadcast area 30, the information terminal apparatus 100 refers to the key station group information and uses the same key as the frequency of the station being received. Get the frequencies of other stations belonging to the station group. Also here, the information terminal device 100 acquires the frequencies of the relay station A1 and the relay station A2.

  The key station group table 141 is a table that stores, for each key station, key station group information in which the frequencies of broadcast radio waves of stations that broadcast the same content are collected. FIG. 3 is a diagram illustrating an example of key station group information. As shown in the figure, the key station group information is information configured by associating the channel of the key station with the channels of a plurality of relay stations that relay the broadcast of the key station. The channel here is identification information for uniquely identifying a station, and each channel is assigned a unique frequency. Specifically, as shown in the figure, the channel is represented by a channel-specific number such as “4ch” or “53ch”.

  The channels belonging to the key station group information are further classified for each broadcast area. Here, the broadcast area is an area where each station covers the broadcast, which is determined based on the reach of the broadcast radio wave. Specifically, the broadcast area is represented by an identifier unique to each broadcast area, such as “Code42” and “Code033”. In the figure, “Code 040/037, Code 042/046” indicates that broadcast areas “Code 040”, “Code 037”, “Code 042”, and “Code 046” are covered by the same station. Yes.

  For example, the key station group 50 shown in the figure is a group in which stations having the same contents as the broadcast of the key station “4ch” are grouped, and eight types of channels (4ch, 16ch, 35ch, 36ch, 42ch, 51ch) are collected. , 53ch, 54ch) are classified into 19 broadcast areas (Code 031 to 049).

  The affiliated station group table 142 is a table that stores affiliated station group information that summarizes the frequencies of broadcast radio waves of the same affiliated key stations for each affiliated station. FIG. 4 is a diagram illustrating an example of affiliated station group information. As shown in the figure, the affiliated station group information is information in which the channels of the same affiliated key stations are grouped into the same affiliated station group, and the channels belonging to the affiliated station group information are further classified for each broadcast area.

  For example, the key station group 60 shown in the figure is a group in which key stations of the same series as the broadcasting of the key station “4ch” are grouped, and five types of channels (4ch, 39ch, 51ch, 52ch, 54ch) are 5 The broadcast areas are classified into code areas (Code 042, 135, 254, 357, 495).

  The control unit 150 is a control unit that performs overall control of the information terminal device 100, and includes a radio wave quality monitoring unit 151, a frequency setting unit 152, and a process selection receiving unit 153 as those related to the present invention. Although not shown here, the control unit 150 demodulates the broadcast radio wave received by the TV tuner 110 and outputs a television broadcast image obtained thereby to the display unit 120. A functional part is also provided.

  The radio wave quality monitoring unit 151 is a processing unit that monitors whether the audio data of the broadcast radio wave is stereo audio or monaural audio during reception of the broadcast radio wave. Specifically, the radio wave quality monitoring unit 151 always inputs audio data output from the TV tuner 110 and confirms whether the audio data is stereo audio or monaural audio. The result is notified to a frequency setting unit 152 described later.

  The frequency setting unit 152 is a processing unit that automatically sets the reception frequency. Specifically, when the confirmation result of the audio data notified from the radio wave quality monitoring unit 151 is monophonic for a predetermined time, the frequency setting unit 152 uses the processing selection receiving unit 153 described later to use It is confirmed whether or not the selection to move the received frequency is accepted from the person. Then, the frequency setting unit 152 performs the process related to the setting of the reception frequency described below only when the selection for moving the reception frequency is accepted.

  In this case, the frequency setting unit 152 determines that the broadcast radio wave being received is weak, and first displays a frequency change notification dialog on the display unit 120 to notify the user that the setting of the reception frequency is to be changed.

  Subsequently, the frequency setting unit 152 refers to the key station group table 141 and belongs to the same key station group as the channel of the broadcast radio wave being received, and the broadcast area is set by the process selection receiving unit 153 described later. Get the frequency that is the same as the destination area.

  Then, the frequency setting unit 152 sets the acquired frequency as the reception frequency in the TV tuner 110, and then confirms the confirmation result of the audio data notified from the radio wave quality monitoring unit 151, and the audio data is stereo audio. If this is confirmed, the reception frequency set in the TV tuner 110 at that time is fixed.

  On the other hand, if it is confirmed that the audio data is monaural audio after setting the reception frequency, the frequency setting unit 152 should continuously receive the same broadcast at the frequency in the area set as the destination. Referring to the key station group table 141 again, the frequency of another channel belonging to the same key station group as the channel of the broadcast radio wave being received is acquired.

  Then, the frequency setting unit 152 confirms the confirmation result of the audio data notified from the radio wave quality monitoring unit 151 while setting the acquired frequencies one by one as the reception frequency in the TV tuner 110, and the audio data is stereo. When it is confirmed that the voice is received, the reception frequency set in the TV tuner 110 at that time is fixed.

  On the other hand, if it is not confirmed that the audio data is stereo audio, it is determined that it is impossible to receive the same content broadcast, and first the user is notified that the broadcast station is to be changed. The broadcast station change dialog for displaying is displayed on the display unit 120. FIG. 7 is a diagram illustrating an example of a broadcast station change dialog.

  Subsequently, the frequency setting unit 152 refers to the affiliated station group table 142 and acquires the frequency of the channel of another key station belonging to the same affiliated station group as the channel of the broadcast radio wave being received.

  Then, the frequency setting unit 152 confirms the confirmation result of the audio data notified from the radio wave quality monitoring unit 151 while setting the acquired frequencies one by one as the reception frequency in the TV tuner 110, and the audio data is stereo. When it is confirmed that the voice is received, the reception frequency set in the TV tuner 110 at that time is fixed.

  Furthermore, when the reception frequency is set (changed) by any one of the above-described procedures, the frequency setting unit 152 sets another change in the same broadcasting area as the channel set here in the key station group table 141. Each channel is also set as a reception frequency. Thereby, when the reception frequency of one channel is set, all the channels that can be received at that place can be received.

  The process selection receiving unit 153 is a processing unit that receives a selection as to whether or not to execute the process related to the setting of the reception frequency by the frequency setting unit 152. Specifically, the process selection accepting unit 153 displays a movement correspondence setting dialog on the display unit 120, and determines whether or not to perform movement correspondence of the reception frequency by the radio wave quality monitoring unit 151 and the frequency setting unit 152 from the user.

  Subsequently, the television function unit of the control unit 150 sets the frequency of the area designated as the movement source to the tuner 110 as a reception frequency (step S103), and starts the video output of the television broadcast received by the TV tuner 110. (Step S104).

  Thereafter, the frequency setting unit 152 confirms whether or not the television broadcast is a stereo audio program. Here, when the television broadcast is not a stereo audio program, the frequency setting unit 152 continues the same confirmation until the stereo audio television broadcast starts (step S105, No), and the television broadcast is a stereo audio program. When it is confirmed that the program is a program (step S105, Yes), it is confirmed whether or not the audio data output from the TV tuner 110 is stereo audio.

  Here, while confirming that the sound data is stereo sound (Yes in step S106), the frequency setting unit 152 continues the same confirmation, and the sound data is not stereo sound (is monaural sound). (Step S106, No), and after confirming that the monaural sound has continued for a predetermined time (step S107, Yes and No), it is determined that the frequency designated as the movement source cannot be received. (Step S108).

  Then, the frequency setting unit 152 confirms ON / OFF corresponding to movement, and if the movement correspondence is OFF (No in step S109), the frequency setting unit 152 sets the reception frequency without performing the following series of processes. This process is terminated. On the other hand, when the movement correspondence is ON (step S109, Yes), the frequency setting unit 152 displays the frequency change notification dialog on the display unit 120 (step S110), and then whether or not the movement destination is set. To check.

  If the destination has been set (step S111, Yes), the frequency setting unit 152 sets the frequency of the area specified as the destination as the reception frequency (step S112), and further, step Returning to S105, the processing is continued. On the other hand, if the destination has not been set (step S111, No), the frequency of other broadcast radio waves belonging to the same key station group as the frequency of the received broadcast radio wave is referred to the key station group table 141. Is acquired (step S113), and the frequency of the broadcast radio wave in which the audio data can be received as stereo audio is detected.

  Here, when the frequency of the broadcast radio wave that can be received by the audio data as stereo sound is detected (step S114, Yes), the frequency setting unit 152 sets the frequency as the reception frequency in the TV tuner 110 (step S115). Further, the process returns to step S105 to continue the processing. On the other hand, when the frequency of the broadcast radio wave that can be received as stereo sound is not detected in the audio data (No in step S114), the frequency setting unit 152 displays that the current location is not the designated area. Displayed on the unit 120 (step S116), and by referring to the affiliated station group table 142, obtains the frequency of another broadcast radio wave belonging to the same affiliated station group as the frequency of the broadcast radio wave being received (step S117). Then, the frequency of the broadcast radio wave that can be received by the audio data as stereo sound is detected.

  Here, when the frequency of the broadcast radio wave that can be received by the stereo data as audio data can be detected (step S118, Yes), the frequency setting unit 152 displays a broadcast station change dialog on the display unit 120 (step S119). The frequency is set in the TV tuner 110 as a reception frequency (step S120), and the process returns to step S105 to continue the process. On the other hand, when the frequency of the broadcast radio wave that can be received by the stereo data as audio data cannot be detected (No in step S118), the frequency setting unit 152 informs the display unit 120 that the video output of the television broadcast cannot be continued. Display (step S121), and a series of processing relating to the setting of the reception frequency is terminated.

  As described above, in the present embodiment, when broadcast radio waves having different frequencies are transmitted from a plurality of broadcast stations, the same contents are propagated and a plurality of broadcast radio waves having different frequencies are related. Information is stored in the key station group table 141 as key station group information, and the radio wave quality monitoring unit 151 monitors the quality of the broadcast radio wave during reception of the broadcast radio wave, and the monitored quality does not satisfy the predetermined quality. In this case, based on the key station group information stored in the key station group table 141, the frequency setting unit 152 sets the frequency of another broadcast radio wave belonging to the same key station group as the received broadcast radio wave as the reception frequency. Therefore, it is possible to narrow down the frequency for determining whether or not reception is possible to only the frequency of the broadcast radio wave that propagates the broadcast of the same content. Of when a change is needed, it is possible to change the setting of the automatic reception frequency in a short time.

  Further, in this embodiment, information related to a group of a plurality of broadcast radio waves that propagate the same part of the content and have different frequencies is stored in the affiliated station group table 142 as affiliated station group information, and the frequency setting unit When there is no broadcast radio wave satisfying a predetermined quality among broadcast radio waves belonging to the group stored as the key station group information 152, based on the affiliated station group information stored in the affiliated station group table 142, Since the frequency of other broadcast radio waves that belong to the same affiliate group as the broadcast radio wave is set as the reception frequency, even if the frequency that propagates the broadcast of exactly the same content could not be set as the reception frequency, Depending on the time zone and day of the week, the frequency of a broadcasting station that may be broadcasting the same program can be set as the reception frequency.

  Also, in this embodiment, broadcast radio waves belonging to the group stored in the key station group table 141 as key station group information are stored in association with broadcast areas, respectively, and when the frequency setting unit 152 sets the reception frequency, Broadcast radio wave reception frequency that propagates other contents of broadcast is set to the same frequency as the broadcast radio wave area that propagates other contents and that corresponds to the set reception frequency. Since the setting is made, the setting of each reception frequency can be simultaneously changed for broadcast stations other than the broadcast station that was actually viewed by the user when the reception frequency was set.

  In the present embodiment, the group stored in the key station group table 141 as key station group information is composed of broadcast radio waves associated with the destination area and broadcast radio waves associated with the source area. The radio wave quality monitoring unit 151 monitors the quality of the broadcast radio wave during reception of the broadcast radio wave associated with the movement source area. If the monitored quality does not satisfy the predetermined quality, the frequency setting is performed. Based on the information stored in the key station group table 141 as the key station group information, the unit 152 sets the reception frequency to the frequency of the broadcast radio wave associated with the destination area. If the destination area is set, it is possible to narrow down the frequency for determining whether or not reception is possible to only the frequency of the movement source area and the frequency of the movement destination area. It is possible to change the setting of reception frequency in a shorter time.

  Further, in this embodiment, only when the process selection receiving unit 153 receives a selection as to whether or not to execute the process related to the setting of the reception frequency and receives a selection to execute the process related to the setting of the reception frequency, Since the frequency setting unit 152 executes the process, when it is not necessary to automatically change the reception frequency, such as when viewing a broadcast without moving, the process is stopped and power consumption due to operation of the apparatus is stopped. Can be suppressed.

  In this embodiment, the radio wave quality monitoring unit 151 monitors whether the audio data propagated by the broadcast radio wave is stereo audio or monaural audio, and based on the monitoring result, the frequency setting unit 152 Because it determines whether or not the quality of the broadcast radio wave satisfies the specified quality, if the received broadcast radio wave becomes weak, the audio data of the stereo broadcast deteriorates to become monaural audio.
