  As described above, if a mobile terminal with a conventional 1Seg broadcasting reception function is entered, the reception rod antenna is manually extended or the reception location is moved to a place with a good view when entering a reception-insensitive area of 1Seg broadcasting. There have been attempts to improve broadcast reception based on user intuition. An object of this invention is to provide the portable terminal which can aim at the reception improvement in the reception insensitive area of 1seg broadcasting, without depending on a user's intuition.

  The portable terminal having the one-segment broadcast reception function includes a position information acquisition unit that acquires position information from a global positioning system (GPS) satellite, and one-segment broadcast reception guide information corresponding to the position information. Reception improvement method information display for displaying information of reception improvement method in a broadcast reception insensitive area based on the one-segment broadcast reception guide information acquisition means fetched from the memory of the server or its own terminal and the one-segment broadcast reception guide information corresponding to the position information Means.

  According to this portable terminal, the broadcast reception improvement information is stored in the server of the Internet site or the memory in the portable terminal for each reception insensitive area of the one-segment broadcasting, and the mobile terminal uses the global positioning system (GPS) function to By displaying the broadcast reception improvement information corresponding to the location of the terminal, it is possible for the user to easily view the one-segment broadcasting without relying on intuition, such as moving so as to avoid insensitive areas. Thereby, the trial of the reception improvement in the broadcast reception insensitive area by the user is not performed, and the wasteful consumption of the battery can be avoided.

  FIG. 1 is an explanatory diagram of reception improvement in a broadcast insensitive zone by the disclosed mobile terminal. In the figure, reference numeral 1-1 denotes a mobile phone network communicable area where communication can be performed via a mobile phone network by a mobile terminal, and an area 1-2-1 to 1-4 where one-seg broadcasting can be received. Is assumed to be a dead zone where it is impossible to receive one-segment broadcasting except for those areas 1-2 to 1-4.

  The mobile terminal 1-5 receives position information by a global positioning system (GPS), acquires one-seg broadcast reception guide information corresponding to the position information, and in accordance with the one-seg broadcast reception guide information, a built-in antenna The gain adjustment of the amplifier that amplifies the received signal is performed, and when the reception is not improved only by the gain adjustment, a message notifying the use of the external antenna and the receivable direction is displayed.

  In other words, the position information acquisition function by the global positioning system (GPS) of the mobile terminal 1-5 is utilized to acquire position information such as the latitude, longitude, and ground height of the location, and one-segment broadcasting reception corresponding to the position information is received. Guide information is received from a server at an Internet site via a mobile phone network. Alternatively, the one-segment broadcast reception guide information corresponding to the position information is acquired from the one-segment broadcast reception guide information already stored in the memory of the terminal itself.

  Since the transmission wave of the one-segment broadcasting is directional in the UHF band, the built-in antenna of the portable terminal 1-5 is based on the information on the direction and height difference of the broadcasting station viewed from the location of the portable terminal 1-5. Pull out an external antenna such as a rod antenna, and obtain the one-seg broadcasting reception guide information corresponding to the location such as which direction the external antenna should be received to improve reception If it is possible, reception can be improved.

  Therefore, the one-seg broadcast reception guide information corresponding to the location is searched for whether or not the one-seg broadcast reception guide information corresponding to the location is already stored in the own terminal. Download.

  Then, according to the one-seg broadcast reception guide information, adjust the gain of the built-in antenna, or notify the user of the use of the external antenna and the direction of its direction, or the direction of the receivable area and the distance traveled to it. A message to be notified is displayed on the terminal screen or notified by sound, light, vibration, or the like.

  FIG. 2 shows a display example in which the one-segment broadcasting reception guide information is displayed on the mobile terminal. When entering a broadcast reception insensitive area during reception of one-segment broadcasting, as shown in the figure, for example, reception improvement information such as “Please move 10 meters to the east of the 1seg reception insensitive zone” is displayed on the screen in characters. The user sees the reception improvement information, recognizes the direction and distance of the broadcast receivable area, and moves to the broadcast receivable area, thereby improving the reception of the one-segment broadcasting.

  FIG. 3 shows an example of a recording file of one-segment broadcasting reception guide information. The recording file is information that is the basis of the one-segment broadcast reception guide information displayed by the application software, and includes information indicating that the one-segment broadcast reception dead zone and reception improvement information corresponding to the position information. . These pieces of information are stored as a database in a server at the Internet site, and a part of the information is downloaded from the server by a mobile terminal and stored in the mobile terminal.

  FIG. 4 is a processing flow for displaying the one-segment broadcasting reception guide information. First, a database storing the one-segment information reception guide information including the receivable area information and the reception improvement information is built in a server accessed from the mobile terminal (4-1).

  Radio waves are radiated from the global positioning system (GPS) satellite (4-2), and the portable terminal receives the radio waves and calculates position information (4-3). The mobile terminal monitors the change in the position information based on the difference from the previously calculated position information, and determines whether or not the position information has changed significantly by comparing with the threshold value (4-4).

  When the mobile terminal detects that the position information has changed significantly, it generates a trigger for requesting the capture of the one-segment broadcasting reception guide information (4-5). When the trigger is generated, the one-seg broadcast reception guide information corresponding to the position information of the current location is fetched from the server via the mobile phone network, or is already stored if already stored in the own terminal. The one-seg broadcast reception guide information is read.

  When the 1Seg broadcast reception guide information is fetched from the server, the 1Seg broadcast reception guide information is stored in the memory in the own terminal as backup information (4-6). Thereafter, the one-segment broadcasting reception guide information having the same position information is read from the memory, and the process of repeatedly accessing the server via the cellular phone network can be omitted.

  Based on the one-segment broadcasting reception guide information, the portable terminal determines whether or not the current location is in the one-segment broadcasting reception insensitive area (4-7). If the current location is an area where the 1Seg broadcast can be received, the reception screen of the 1Seg broadcast is displayed as it is (4-8). If the current location is a one-segment broadcast reception insensitive area and reception improvement information exists, the reception improvement information is displayed according to the one-segment broadcast reception guide information using the application software (4-9), and the one-segment broadcast reception screen The reception improvement information is multiplexed and displayed (4-10).

  The mobile terminal transmits the one-segment reception insensitive area information and reception improvement information input by the user's manual operation to the server via the mobile phone network (4-11), and the server is transmitted from the mobile terminal. The one-seg broadcast reception guide information display database is updated based on the one-seg reception insensitive area information and the reception improvement information.

  The one-segment broadcast reception guide information has a function of allowing a user to edit or modify the information on the mobile terminal and transmitting the modified one-segment broadcast reception guide information to the server. As a result, the server side is updated to correct the error of the one-segment broadcasting reception guide information, and the accuracy of the one-segment broadcasting reception guide information can be improved by updating by a large number of users. If there is a building and reception is impossible, the user can edit the one-segment broadcast reception guide information independently so that reception of the one-segment broadcast is automatically turned off.

  In this way, using the GPS function, the latitude / longitude / ground height of the receiving point and the azimuth / elevation information of the broadcasting station at that point are obtained from the server via the mobile phone communication network, and the one-segment broadcasting is best By displaying the guide information so that it can be received in the state, even if it is insensitive zone of receiving 1Seg broadcast, it is possible to notify the user how to escape from that zone and receive 1Seg broadcast Become.
