Description

  The present invention relates to presetting of an apparatus including a wireless reception system, and more particularly to a technique for providing conditions for performing presetting.

  Conventionally, in a mobile radio reception system, every time a broadcast station uses a different frequency, the channel of the broadcast station must be preset again. In particular, portable and in-vehicle wireless reception systems (radio, TV, etc.) often receive broadcasts while moving, and as shown in FIG. 14, broadcasts cannot be received if the distance from the broadcast station is increased on the movement route. There is a case. In addition, in a mountainous area or the like, the frequency may change even in a broadcast receivable area (switch to a satellite station), and thus there is a problem that reception cannot be continued unless a satellite station is searched and reselected.

  Further, in the conventional radio reception system, the frequencies of a plurality of broadcasting stations are set in advance, and at the time of channel selection, the frequency data specified by the channel selection number is input to the receiver to perform channel selection immediately.

  Therefore, according to Patent Document 1, from a mobile communication radio base station arranged in the whole country, a radio wave transmitting a predetermined area code for each area to which each radio base station belongs is moved to , Detect the area code, and reset the frequency used by each broadcasting station operating in the area as frequency data from the area code.

  When the radio reception system moves, first, in the destination area, the area code representing the area from the mobile radio base station is received, and the use frequency of the broadcasting station operating in the area is determined from the area code. Proposals have been made that can be re-preset automatically and always select a channel with a simple operation.

Further, according to Patent Document 2, the area where the broadcast radio wave from the FM broadcast station can be received is limited, but the same program can be heard from FM broadcast stations in other areas.
In such a case, it is possible to listen to the same program in another area by adjusting the reception frequency by using numeric keys or dials provided in the wireless reception system, or by selecting an auto search function or an auto scan function. Even in the same program, if the area is different, the transmission frequency of the broadcasting station is different. Therefore, the user must continue to operate the numeric key, dial, and auto search key provided on the apparatus until the broadcast of the same program is received. Therefore, a wireless reception system that uses the alternative frequency data of the broadcast station that broadcasts the same program superimposed on the broadcast radio wave and automatically tunes to the broadcast radio wave of the broadcast station that broadcasts the same program even if the area is moved is proposed. Has been.

  According to Patent Document 3, the broadcast program is automatically tracked to greatly reduce the channel number setting time, and the channel number is sequentially set without being affected by the position change of the apparatus due to movement and other radiated radio waves and noise. There are proposals for continuous reception of broadcast programs by sequentially updating channel numbers in a reception environment that can be updated and has a weak electric field strength.

According to Patent Literature 4, when performing presetting, a change content of a preset is displayed to the user, and then the user switches based on the display content.

The oscillator 27 is controlled by an information processing circuit 30 (to be described later) to change the oscillation frequency in order to perform a desired channel selection by the mixer 22.
The interface unit 3 includes a key panel 28 (operation means), a display (liquid crystal or the like: display means) 29, and the like. The key panel 28 is used by the user for channel selection, volume adjustment, various settings, and the like. Here, although it is set as a key panel, it is not limited, What is necessary is just a means which a user can input. The display 29 displays channel selection information (broadcast station information, etc.), messages, display of reception intensity, and the like. For example, liquid crystal.

  The control unit 4 includes at least an information processing circuit 30 (control), and controls the entire mobile device on which the wireless reception system is mounted. For example, if it is a mobile phone, the exchange control with the mobile phone unit is controlled, and if it is an MP3 (MPEG1 Audio Layer 3) player, the exchange with the MP3 player unit is controlled. The information processing circuit 30 also controls the key panel 28 and the display unit 29 described above, and also controls the information collection unit 5 described later. It also controls the channel selection of the wireless reception units 1 and 2.

  The information collecting unit 5 includes a memory 31 and a communication circuit 32 (which can be connected to the Internet or the like). The memory 31 stores channel preset information collected from the communication circuit 32. The communication circuit 32 collects necessary information through the Internet, a dedicated line, and a wireless LAN.

  For example, a system that provides an Internet environment such as a WLAN (Wireless Local Area Network) is provided to an MP3 player, and its location information can be detected using a hot spot (registered trademark No. 4539387).

  Then, an access point such as a wireless LAN or Bluetooth is installed, and position information and the like are acquired from a space where a wireless Internet connection service is provided to an unspecified number of users. Here, until the ISP (Internet service provider, etc.) provides commercial services, restaurants, etc. to users, there are a wide variety of forms of information provision, so hotspots correspond to each provider. Different communication standards. Therefore, it is necessary to prepare and use a device that supports the same communication standard as the hot spot side on the user side. Therefore, the hot spot standard is displayed, and further, processing corresponding to the hot spot standard is performed manually or automatically. For example, preset corresponding to the hot spot standard is performed.

In addition, a list of broadcast stations that can be received from a database is searched from position information obtained from a hot spot or the like, and a preset for selecting a broadcast station suitable for the place where the user is is automatically performed.
Further, for example, location information may be managed at a municipal level, and even if the broadcasting station is the same, depending on the location, the satellite station may be automatically switched so that a stable radio wave reception state can be continued even when moving.
(Operation of the control unit 4: preset setting and broadcast station switching operation)
FIG. 2 shows a flow of the present invention. A broadcast transmitted from the broadcast station is received by the reception antenna 6. In step S21, based on the received reception strength, the user selects whether to update information by presetting. At this time, the user refers to the display unit 29 of the interface unit 3 and selects whether or not to update using the key panel 28 or the like.

When updating the preset, preset setting (step S22) is performed. The preset setting in S22 is shown in FIG.
When performing the preset setting, first, in step S31, it is determined whether to perform the preset setting automatically or manually. Whether to perform it automatically or manually is set in advance. For example, the user performs automatic / manual switching setting in the control unit 4 using the key panel 28 or the like.

  In the case of manual setting (when there is no position information), the user sets preset information (information included in the area information (database) in FIG. 4 and main station-satellite information (database) in FIG. 5) necessary for presetting. To do. In step S32, information recorded in the area information database as shown in FIG. 4 is called, and a broadcast station desired to receive in that area is set. For the area information, a list of areas can be called from the area information database shown in FIG. 4, and the user can manually select a desired area.

  Here, the area information database has at least “region” (region information), “prefecture name” (prefecture name information), “area code”, “area name”, etc., and a code is assigned to each area. It has been. In “Region” in Japan, information divided into Hokkaido, Tohoku, Kanto, Tokai, etc. is recorded. In “Prefecture name”, the name of the prefecture belonging to the area divided by “Region” is recorded. The “area code” is composed of “area ID”, “sub-area ID”, and the like, and these IDs are assigned based on “region” and “prefecture name”. The area name corresponding to the area code is recorded in “area name”.

Next, in step S33, the frequency of each broadcasting station is called and set from the area information database and the main station-satellite information database shown in FIG.
The main station-satellite information database includes at least “broadcast station” (broadcast station information), “frequency” (frequency information), “main station / satellite” (main station / satellite identification information), and “area code”. A code is assigned to each broadcasting station. In “Broadcasting station”, the name of the broadcasting station is recorded. For example, a full name or an abbreviated name may be used. In “frequency”, a frequency corresponding to each broadcasting station is recorded. In the “main station / satellite”, a code for identifying whether it is a main station or a satellite is recorded. For example, the main station is “1” and “0” is a satellite. Further, the area code shown in FIG. 4 is assigned to the “area code”. With this area code, it is possible to associate which broadcast station can receive the broadcast for each area, and display it on the display means.

  Next, when performing presetting automatically, position information is acquired from the communication circuit 32 of the information collection unit 5 from the Internet, a hot spot, GPS, or the like in step S34. For example, in the case of a WLAN, position information is acquired from a connection destination terminal. Here, when communication is performed using a hot spot, if the communication method is different, the communication method is changed by a method set in advance automatically or manually by the user to communicate with the hot spot. Also, a communication method database for changing these communication methods is prepared. 4 and 5, the database such as the communication method is recorded in the memory of the control unit 4 or the memory 31 of the information collecting unit 5.

  In step S35, the channel preset information is acquired from the communication circuit 32 from a site on the web using a public line, a dedicated line, the Internet, or the like. This channel preset information is information that rewrites the contents of the preset information (information contained in the database) shown in FIGS. 4 and 5 recorded in the mobile device equipped with the wireless reception system. In addition, for example, information on a newly opened broadcasting station is updated in the channel preset information, so that the latest reception environment information can be provided at any time by incorporating the preset information into the preset information. In addition, when rewriting is not desired, the user can cancel it.

In step S36, preset information such as the frequency of each broadcasting station is called and set from the area information database and the main station-satellite information database.
When the preset information is not updated, in step S23, the user selects the channel assigned to the broadcast station to be received by using the key panel 28, for example, and matches the desired channel. In step S24, a signal for setting the frequency is transmitted from the control unit 4 to the oscillator 19 of the wireless reception unit 1 in order to set the desired channel. When the frequency is set, sound of a desired channel is output from the speaker 18.

  In step S25, a reception signal (RSSI signal) for monitoring the reception intensity is also input to the wireless reception unit 2 side via the distributor 7 in parallel, and monitoring of the reception intensity is started. Here, the reception strength may be a reception sensitivity or may be displayed by other reception characteristics. When the wireless receiver 2 is not provided, the RSSI signal on the wireless receiver 1 side is used. In step S26, information such as the frequency of channels (including satellites) that have been preset and made receivable is displayed on the display, and the control unit 4 changes the oscillation frequency of the oscillator 27 to a receivable channel and scans as needed. (A user or a period is set in advance, and scanning is performed at the set period. In particular, the period may not be constant. For example, when the reception intensity level of the channel currently selected has dropped, the scanning period is shortened. The received intensity is measured for each channel and displayed on the display 29.

  FIG. 6 shows an example of display display. The case where the FM broadcast channel selection screen is displayed on the display 61 of the mobile device (the display 29 or the key panel 28 as a touch panel) will be described.

  “Tokyo” shown in the broken line part 62 is called from the area information database to display the current position. A broken line portion 63 is an indicator showing the reception intensity of each broadcasting station. The number displayed in the broken line part 64 indicates the number assigned by the user in the mobile station, for example, of the set broadcasting station. A broken line portion 65 indicates a currently receivable broadcasting station and is indicated by ▽ (black inverted triangle). A broken line portion 66 indicates the frequency of each broadcasting station. A broken line portion 67 indicates the name of the broadcasting station (for example, NNN, FM_T, FM_J... FM795).

  In the figure, only the portion of channel 6 is displayed larger than the others, indicating that the channel is currently selected by the user. Further, the display information of the selected channel may be indicated by blinking or cursor display. In addition, as shown in FIG. 7, the reception intensity of the community FM as indicated by the broken line portion 71 may be displayed. Information such as the community FM can also be acquired by channel preset information.

  Further, the reception strength indicator indicated by the broken line portion 63 is displayed as shown in FIG. As shown in FIG. 8 (a), the RSSI voltage is divided into ranges such as 0.0, 0.1, 0.2, 0.5 (V) numerically, and 0.0 or more and less than 0.1V. If it is 0.1V or less and less than 0.2V, the sensitivity is the lowest, if it is 0.2V or more and less than 0.5V, the sensitivity is degraded, and if it is 0.5V or more, the medium sensitivity is displayed. Good.

  In addition, the bar graph of FIG. 6 represents antenna sensitivity with good sensitivity, medium sensitivity, low sensitivity, minimum sensitivity, and no reception, as shown in FIG. 8B. Further, it may be represented as a traffic light as shown in FIG. If the sensitivity is good, the traffic light is displayed in blue. If the sensitivity is medium, the traffic light is displayed in yellow. If the sensitivity is poor, the traffic light is red. If the sensitivity is low, red is lit. Turn off all the displays. Further, if a satellite station can be selected, an arrow may be displayed on the display portion provided below the traffic light to notify the user.

Not only the bar graphs and traffic lights described above, but also figures, patterns, and colors that can be recognized by the user may be used. The same applies to the above-described ▽ (black inverted triangle).
Next, in step S27, the reception intensity of the broadcasting station of the channel being received by the reception system (main tuner) 1 is measured, and the reception intensity reference value that determines whether the preset reception is good or bad, Determine whether the reception sensitivity is good or bad. At this time, the reception intensity reference value may be set by the user. If the reception intensity is good, the process returns to S25. On the other hand, if it is determined to be defective, the display of the reception intensity indicator is changed in step S28.

  Next, in step S29, it is determined whether or not the reception intensity is the lowest level. If it is the lowest level (Yes), the broadcasting station is switched in the process of step S210. If it is not the lowest level, the process returns to S26. Here, the reception strength level is divided into several levels as described above (divided into several levels as in the case of bar graphs and traffic lights), and the minimum level is set in advance and set. When the level is reached, the process proceeds to S210.

  Here, as shown in FIG. 9, when the reception intensity of the currently selected channel 6 shown by the broken line portion 91 is deteriorated or when the reception state can be improved by moving to the satellite station, for example, ▽ (black The user may be prompted to switch by turning on an inverted triangle) or changing the color. Then, the user calls the satellite station selection screen 92 in order to select the satellite station. The calling method is not particularly limited, but a method of placing the cursor on the channel 6 and clicking it may be used. Then, information on each broadcasting station is displayed on the satellite station selection screen 92 together with the satellite stations (SAT_FFF to SAT_SSS). At that time, the reception strength is also displayed, so that the user can select a channel with reference to the reception strength. Here, the display on the screen is performed based on the database shown in FIGS.

  Next, in S210, broadcasting station switching is performed. FIG. 10 shows a flow for switching broadcast stations based on the reception intensity and preset information of broadcast stations in the receivable area. In step S41, the satellite station reception intensity is acquired. In step S42, for example, when all the satellite stations set in the preset information are poorly received, the reception channel strength deterioration state is displayed, and a message for prompting the channel change is also displayed. A notification for displaying the message “Please change channel” as shown by the broken line part 111 in FIG. 11 is sent. In addition, a notification for notifying a warning sound or a message by voice is set on the display 29 (display unit).

  In step S43, if the automatic change function of the satellite station is ON, the process proceeds to step S45. On the other hand, if it is OFF, the process proceeds to step S44, and a message for prompting the satellite station to change the frequency is sent. For example, as shown by a broken line portion 121 in FIG. 12, a notification for displaying a message “Please change the frequency” is sent. In addition, a notification for notifying a warning sound or a message by voice is set on the display 29 (display unit).

  In step S45, the reception strength of each satellite station is compared and the strongest one is selected. In step S46, the currently received frequency is switched to the satellite station frequency. At this time, the user may confirm whether the frequency can be changed.

  In step S47, the display (frequency) on the display is switched. The satellite station frequency is changed and displayed as indicated by a broken line portion 131 shown in FIG. In step S48, the display indicates that the frequency has been switched to the satellite. Satellite station reception marks and satellite station names are displayed as indicated by broken lines 132 and 133 shown in FIG. The contents indicated by the broken lines 131, 132, 133 described above may be any figure, pattern, color, or character that can be recognized by the user.

With the above configuration, for example, a system that provides an Internet environment such as a WLAN is provided, and its own position information can be detected using a hot spot or the like.
Also, if the location detection function reveals your location (possible at the municipal level), the channel is automatically preset. If the position cannot be detected, the broadcast station can be preset by calling the preset data of the broadcast station assigned to each area by manually specifying the area.

  In addition, when the wireless reception system comes near the coverage area boundary of the receiving broadcast station, it is displayed that it is difficult to continue reception (for example, the broadcast station name is blinked or the color is displayed lightly) , Urge the user to select another broadcast station or not to leave the cover area. Furthermore, by obtaining information from the Internet, it is possible to update and use a list of small-scale broadcast stations such as increase / decrease of broadcast stations and community FM as needed.

  By displaying the reception level using a bar graph or color coding, it is possible to select a channel that allows stable reception, or to switch to a satellite or adjust the antenna direction. In addition, it is possible to confirm whether or not reception is possible by changing the direction and type of the antenna and the reception location using the reception intensity indicator.

  Since the reception intensity of the preset channel can be monitored in real time by the sub-tuner, the optimum reception environment can be maintained by automatically switching the frequency for the broadcasting station where the satellite station exists.

  The present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the gist of the present invention.
