Description

  The present invention relates to a portable terminal capable of receiving a television broadcast, and particularly to a device capable of receiving a television broadcast by a small-scale broadcasting station in a narrow reception area.

  As portable television broadcasting, television broadcasting using one segment of terrestrial digital television broadcasting (hereinafter, abbreviated as one-segment broadcasting) has been spreading. In terrestrial television broadcasting, the band of one channel is divided into 13 OFDM (Orthogonal Frequency Division Multiplex) segments. One-segment broadcasting is a television broadcasting using one of these 13 segments. Currently, general one-segment broadcasting broadcasts the same program from the same antenna as existing terrestrial digital television broadcasting. Such general one-segment broadcasting has output power that can secure a wide reception area.

  On the other hand, a one-segment broadcasting system by a small-scale broadcasting station in a narrow receiving area using a weak radio wave or the like in a receiving area having a radius of several meters to several tens of meters has been proposed. The specifications of one-segment broadcasting by small-scale broadcasting stations are basically the same as general one-segment broadcasting. For this reason, the user can receive the one-segment broadcasting by the small-scale broadcasting station using the portable terminal capable of receiving the one-segment broadcasting. One-segment broadcasting by a small-scale broadcasting station makes use of the characteristics of weak radio waves, and is used by department stores, convenience stores, restaurants, etc. to provide the latest programs suitable for each region and each store.

  However, the service areas of small-scale broadcasting stations are narrow, and their existence is often unknown due to radio waves. For this reason, it is difficult for an unfamiliar user to grasp where, on which channel, what kind of broadcast is being performed.

  For example, in Patent Document 1, when a channel designated by a user is not registered, a digital broadcast signal that scans a broadcast signal band and has the number as a virtual channel is set for a television channel that can be received. There has been proposed a digital broadcast receiver that can select a channel.

However, in Patent Document 1, there is no description about broadcasting of a small-scale broadcasting station, and since there is one tuner, channel scanning is performed during television reception to select the broadcasting. It is impossible to compile. For this reason, it is not possible or assumed to detect a small-scale broadcasting station while receiving a general television broadcast on a portable terminal.

  In contrast, small broadcast channels are unknown. In the first embodiment of the present invention, a small broadcast station detection process is performed, and when a small broadcast station is detected, the newly detected small broadcast station is notified. Then, a selection display as to whether or not to register the detected small-scale broadcast station is performed. When a small-scale broadcast station is registered, the broadcast is stored in the small-scale broadcast channel storage unit 52 as shown in FIG. The station name, channel, center frequency, and position information are stored. Specifically, for example, a small-scale broadcasting station name “AB Department Store 4F (Women's Clothing)”, a channel “41ch”, a center frequency “641 MHz”, and position information “North latitude 35 degrees 41 minutes East longitude 139 degrees 42 minutes” Is remembered. Actually, the position information is used up to the unit of “second”, but it is omitted here.

  5 and 6 explain the reception of a general broadcast station and the reception of a small-scale broadcast station in the first embodiment of the present invention.

  In FIG. 5, 101 is a general broadcast station, and 102 is a small-scale broadcast station. It is assumed that the user of the mobile phone terminal 1 moves from the point A1 to the point A2, the point A3, and the point A4. In FIG. 5, L <b> 1 is a service area of the small-scale broadcasting station 102. Outside the service area L1, radio waves can be received from the general broadcast station 101, but radio waves from the small-scale broadcast station 102 cannot be received.

  6A shows the reception screen at the point A1, FIGS. 6B to 6E show the reception screens at the point A2, and FIG. 6F shows the reception screens at the point A3. 6 (G) to 6 (I) show the reception screen at the point A4.

  Since the point A1 is outside the service area L1 of the small-scale broadcasting station 102, radio waves are received from the general broadcasting station 101 and the reception screen of the general broadcasting station 101 is displayed as shown in FIG. The

  When moving from the point A1 to the point A2, the service area L1 of the small-scale broadcasting station 102 is entered. In the mobile phone terminal 1 according to the first embodiment of the present invention, as will be described later, detection processing for a small-scale broadcast station is performed while receiving a general broadcast station. For this reason, when entering the service area L1 of the small broadcast station 102, a broadcast wave from the small broadcast station 102 is detected. When the small broadcast station 102 is detected, as shown in FIG. 6B, a notification display 110 indicating that the small broadcast station 102 has been newly detected is displayed. Then, as shown in FIG. 6C, a selection display 111 as to whether or not to register the newly detected small-scale broadcasting station 102 is displayed. Here, when “Yes” is selected, information of the detected small-scale broadcasting station 102 is registered. Then, as shown in FIG. 6D, a selection display 112 as to whether to view the newly detected small-scale broadcasting station 102 is displayed. Here, when “Yes” is selected, as shown in FIG. 6 (E), a notification display 113 indicating that the station has been changed to the small-scale broadcast station 102 is displayed, and the detected reception of the small-scale broadcast station 102 is confirmed. This reception screen is displayed. As a modification, the screen display in FIG. 6C may be omitted, and if Yes is selected on the screen 6D, registration and viewing operations may be performed collectively. Further, when the frequency of the small-scale broadcasting station received in relation to the screen 6 (B) is already registered, the registration operation on the screen 6 (C) can be omitted.

  Between the point A2 and the point A3, the mobile phone terminal 1 is in the service area L1 of the small-scale broadcasting station 102. For this reason, as shown in FIG. 6 (F), the reception of the broadcast from the small-scale broadcasting station 102 is continued.

  When the mobile phone terminal 1 moves out to the point A4, the mobile phone terminal 1 goes out of the service area L1 of the small-scale broadcast station 102, so that the broadcast from the small-scale broadcast station 102 cannot be received. In this case, as shown in FIG. 6G, a notification display 114 indicating that the small broadcast station 102 is out of the service area is displayed. Then, as shown in FIG. 6 (H), a selection display 115 as to whether or not to return to viewing of the original general broadcast station 101 is displayed. Here, if “Yes” is selected, as shown in FIG. 6 (I), the channel returns to the original channel of the general broadcast station, and this reception screen is displayed.

  As described above, in the first embodiment of the present invention, the broadcast wave detection process of the small-scale broadcast station is performed, and when the broadcast wave of the small-scale broadcast station is detected, the detected small-scale broadcast station is notified. For this reason, when there is a small-scale broadcasting station, this can be detected, and the latest program suitable for each region and each store can be received and displayed.

  FIG. 7 is a functional block diagram for explaining the operation of the first embodiment of the present invention. In the embodiment of the present invention, a television broadcast is received by the video reproduction tuner 43 and a channel is scanned by the wave search tuner 44 while being displayed on the display unit 13 to detect a broadcast wave. Then, when a broadcast wave is detected by the search tuner 44, it is compared with the broadcast channel information stored in the general broadcast channel storage unit 51. Judged to be a large-scale broadcasting station. And the GPS function part 41 receives the positional information from a GPS satellite via an antenna, and acquires the positional information on a mobile telephone terminal. When a new small broadcast station is detected, a notification display indicating that the small broadcast station has been newly detected is displayed, and an indication of whether or not to register the newly detected small broadcast station. Is displayed and information on the detected small broadcast station is registered in the small broadcast channel storage unit 52. Then, a selection display as to whether or not to view the newly detected small-scale broadcast station is displayed, and when viewing the detected small-scale broadcast station is selected, the small-scale image in which the channel of the video reproduction tuner 43 is detected is displayed. The channel is switched to the channel of the broadcast station, and the reception screen of the detected small-scale broadcast station is displayed on the display unit 13.

  FIG. 8 is a flowchart showing the operation of the first exemplary embodiment of the present invention. In FIG. 8, when the television reception is activated (step S1), it is determined whether a general broadcast channel or a small-scale broadcast channel is received (step S2).

  When the general broadcast channel is received in step S2, the channel is set from the channel information stored in the general broadcast channel storage unit 51 (step S3), and the set channel is set by the video reproduction tuner 43. Is received (step S4).

  When a small broadcast channel is received in step S2, a channel is set from the channels stored in the small broadcast channel storage unit 52 (step S5) and set by the video playback tuner 43. A channel broadcast is received (step S4).

  Then, detection processing of a small-scale broadcast station by the search tuner 44 is performed (step S6), and it is determined whether or not a small-scale broadcast station has been detected (step S7). If no small broadcast station is detected, the process returns to step S6, and the small broadcast station detection process is continued.

  In the first embodiment of the present invention, the broadcast of the set channel is received using the video playback tuner 43, and the detection processing of the small-scale broadcasting station in step S6 is performed by the search tuner 44. Is called. Therefore, even when a small broadcast station detection process is performed, the reception process of the general broadcast channel is continuously performed.

  When the broadcast of the small broadcast station is detected in step S7, a notification display indicating that the small broadcast station is newly detected is performed (step S8). Then, a selection display as to whether or not to register the channel information of the detected small broadcast station is performed (step S9).

  In step S10, it is determined whether or not the channel information registration of the small broadcast station has been selected. If it is selected in step S10 to register the channel information of the small broadcast station (Yes in step S10), the detected channel information of the small broadcast station is stored in the small broadcast channel storage unit 52. (Step S11). Then, a selection display as to whether or not to view the detected small-scale broadcasting station is performed (step S12).

  If registration of channel information of a small broadcast station is not selected in step S10 (No in step S10), the process goes to step S12 as it is, and a selection display of whether or not to view the detected small broadcast station is performed. Is called.

  In step S13, it is determined whether or not to watch a small broadcast station. When viewing of a small broadcast station is selected (Yes in step S13), the channel of the video playback tuner 43 is set to the channel of the detected small broadcast station (step S14). Then, the video reproduction tuner 43 receives the small-scale broadcast of the set channel (step S15). Thereafter, it is determined whether or not the channel of the small broadcast station can be received (step S16). If the reception is possible, the process returns to step S15, and the reception of the channel of the small broadcast station is continued.

  If it is not selected in step S13 to view the channel information of the small broadcast station (No in step S13), the process returns to step S4, and reception of the initially set channel is held.

  If it is determined in step S16 that the small broadcast station cannot be received, a notification display indicating that it is out of service area is performed (step S17). Then, a selection display as to whether or not to return to the original channel is performed (step S18).

  In step S19, it is determined whether or not return to the original channel is selected. If return to the original channel is selected (Yes in step S19), the original setting channel is restored (step S20). The process returns to S4. If returning to the original channel is not selected in step S19 (No in step S19), the process returns to step S15, and reception of the channel of the small broadcast station is continued.

  As described above, in the embodiment of the present invention, the detection processing of the small-scale broadcasting station is performed by the search tuner in step S6. This small broadcast station detection process will be described in detail.

  In this embodiment, a broadcast wave is detected while a channel is scanned by a search tuner 44 that is separate from the broadcast reception video reproduction tuner 43. If a broadcast wave is detected, it is compared with the broadcast channel information stored in the general broadcast channel storage unit 51. If it is not registered in the general broadcast channel storage unit 51, it is a new small-scale broadcast station. I am trying to judge.

  FIG. 9 is a flowchart showing details of the small-scale broadcast station detection process by the search tuner in step S6. In FIG. 9, the search tuner 44 is activated (step S101). Then, the initial channel is set (step S102).

  It is determined whether or not a broadcast wave is detected in the set channel (step S103). If no broadcast wave is detected (No in step S103), it is determined whether or not scanning of all channels is completed (step S103). Step S104). If all the channels have not been scanned (No in step S104), the next channel is set (step S105), and the process returns to step S103. When scanning of all channels is completed (Yes in step S104), the process returns to step S102 and is set as the initial channel.

  If a broadcast wave is detected in step S103 (Yes in step S103), it is compared with the broadcast channel information stored in the general broadcast channel storage unit 51 to determine whether or not it has been registered in the general broadcast channel storage unit 51. (Step S106). If registered in the general broadcast channel storage unit (Yes in step S106), the process goes to step S104 to determine whether or not all channels have been scanned. If all channels have not been scanned, the next channel is determined. (Step S105), the process returns to Step S103, and when all the channels have been scanned, the process returns to Step S102 and is set as the initial channel.

  When a broadcast wave that has not been registered in the general broadcast channel storage unit 51 is detected in step S106 (No in step S106), this channel can be determined as a newly detected small-scale broadcast channel. In this case, the position information is detected by the GPS function unit 41 (step S107), and the determination result that the channel of the small-scale broadcast has been detected and the information (channel information, position information) of this small-scale broadcast are obtained. Is output (step S108), and the process returns to the main process.

  In the first embodiment of the present invention, as described above, the wave detection tuner 44 is provided separately from the video reception tuner 43 for broadcast reception, so that a small-scale broadcast station can detect even during broadcast reception. it can. The display example shown in FIG. 10 displays icons so that the operation of the video playback tuner 43 and the operation of the search tuner 44 can be understood.

  10, display 123 shows the channel setting state of the video playback tuner 43, display 124 shows the reception state of the video playback tuner 43, display 125 shows the channel setting state of the search tuner 44, and display 126 shows the search. The reception state of the tuner 44 is shown.

  As shown in FIG. 10A, when receiving a general broadcast, in addition to the television image being received, the display 123 shows the channel setting state of the video playback tuner 43, and the display 124 shows the video playback tuner 43. The reception status of is shown. While the general broadcast is being received, the search tuner 44 performs a scanning process, and the display 125 and the display 126 are displayed to indicate that scanning is in progress.

  When a new small-scale broadcasting station is detected by the search tuner 44, as shown in FIGS. 10B and 10C, the display 125 newly detects the channel setting state of the search tuner 44. The channel of the small broadcast station is displayed, and the display 126 displays the reception status.

  Then, when viewing of the newly detected small-scale broadcast station is selected, the channel of the video playback tuner 43 becomes the channel of the newly detected small-scale broadcast station, and as shown in FIG. Is a display of the channel of the set small-scale broadcasting station, and the reception status is displayed on the display 124.

  While receiving a small broadcast station, as shown in FIG. 10E, the display 123 shows the channel of the set small broadcast station, and the display 124 shows the reception status. Is displayed. In addition, the search tuner 44 performs a scanning process, and the display 125 and the display 126 are displays indicating that scanning is in progress.
