  The operation input unit 7 includes, for example, a touch panel integrated with the liquid crystal display of the display device 6 or a button adjacent to the liquid crystal display.

Next, the operation of the broadcast receiving system 100 will be described with reference to the flowchart of FIG. 2, focusing on the operation of creating the second list and the third list and presenting them to the user.
First, in step ST1, the operation input unit 7 receives an input of an operation for setting a destination. The route search unit 31 acquires map data from the map data storage unit 41 and searches for a travel route from the current position of the vehicle to the destination.

  Next, in step ST <b> 2, the list creation unit 32 instructs the tuner control unit 33 to search for a broadcast station that can receive broadcast waves with the broadcast wave receiver 2. The list creation unit 32 obtains the value of the field intensity of the broadcast wave of each broadcast station from the reception status acquisition unit 34 and creates a first list including broadcast stations that can receive the broadcast wave by the broadcast wave receiver 2. .

  At this time, the list creation unit 32 acquires program information included in the broadcast wave of each broadcast station decoded by the decoder unit 22. The reception status prediction unit 35 acquires position information indicating the positions of broadcast stations and relay stations included in the broadcast wave of each broadcast station decoded by the decoder unit 22.

  Next, in step ST <b> 3, the history information transmitting / receiving unit 51 receives other vehicle history information from the cloud server 9. The reception status prediction unit 35 uses the position information acquired in step ST2, the own vehicle history information stored in the history information storage unit 42, and the other vehicle history information received by the history information transmission / reception unit 51, for each broadcast. The broadcast area information of the station and the decrease point data indicating the point where the electric field intensity of the broadcast wave of each broadcast station decreases below the threshold on the route searched by the route search unit 31 are created.

  Next, in step ST4, the reception status prediction unit 35 searches the route search unit 31 by associating the broadcast area information and the lowered point data created in step ST3 with the map data acquired from the map data storage unit 41. Reception status prediction information indicating prediction of broadcast wave reception status of each broadcasting station at each time while traveling on the route is created.

  Next, in step ST5, the list creation unit 32 uses the program information acquired in step ST2 and the reception status prediction information generated by the reception status prediction unit 35 in step ST4, so that the first list created in step ST3 In addition, it is determined whether or not a priority broadcast station with a good reception condition of the broadcast wave is included until the program ends.

  In step ST5, the list creating unit 32 is a broadcast station that is predicted to have a good reception condition of broadcast waves until the vehicle arrives at the destination among the programs that do not end before the vehicle arrives at the destination. May be included in the priority broadcast station.

  If at least one priority broadcast station is included in the first list (step ST5 “YES”), then in step ST6, the list creation unit 32 selects the priority broadcast from the broadcast stations included in the first list. A second list is created by rearranging stations higher than the remaining broadcasting stations.

  On the other hand, if no first priority broadcast station is included in the first list (step ST5 “NO”), then, in step ST6a, the list creation unit 32 and the home broadcast A third list including broadcast stations capable of receiving broadcast waves by the receiving device 11 is created.

  Next, in step ST7, the display device 6 displays the second list created by the list creation unit 32 in step ST6 or the third list created in step ST6a. Alternatively, the display device 6 outputs the second list created by the list creation unit 32 in step ST6 or the third list created in step ST6a as sound.

  Next, in step ST8, the operation input unit 7 accepts an operation of selecting one of the broadcasting stations and the distribution stations included in the second list or the third list. When the display device 6 displays the second list, the tuner control unit 33 switches the tuning of the tuner unit 21 according to the operation input to the operation input unit 7. The display device 6 outputs the video / audio data output from the decoder unit 22 as video and audio. In addition, when the display device 6 displays the third list, the display device 6 transmits the audio data received from the radio distribution server 10 by the Internet program receiving unit 52 according to the operation input to the operation input unit 7. Or the video / audio data received by the home program receiver 53 from the home broadcast receiver 11 is output as video and audio.

  In general, when the travel route includes a tunnel, the broadcast wave receiver 2 cannot receive broadcast waves, while the Internet module 5 may be able to communicate via the Internet line network 8. If the first list does not include any priority broadcast stations, the third list including broadcast stations that can receive broadcast waves at the Internet radio distribution station or the home broadcast receiving device 11 is displayed. Even on a travel route where there is no broadcasting station capable of stably receiving waves, it is possible to preferentially select programs that can be viewed without interruption within a range where Internet communication is possible.

  The display device 6 continues to output video and audio until the broadcast program of the broadcast station selected in step ST8 or the distribution program of the distribution station is completed. When the program ends (step ST9 “YES”), then, in step ST10, the reception status acquisition unit 34 sets the value of the electric field strength of the broadcast wave of the broadcasting station that was watching the program during steps ST8 to ST9. Then, it is stored in the history information storage unit 42 as own vehicle history information. The history information transmission / reception unit 51 transmits the host vehicle history information stored in the history information storage unit 42 to the cloud server 9.

  If the third list is displayed in step ST7 and a broadcast station capable of receiving broadcast waves is selected in step ST8 by the Internet radio program distribution station or the home broadcast receiver 11, the process in step ST10 is skipped. .

  When the broadcast wave receiver 2 and the navigation system 3 are not turned off even after the program ends (step ST11 “NO”), the broadcast receiving system 100 returns to the process of step ST2, and the list creation unit 32 again performs the first operation. Create a list. On the other hand, when the broadcast wave receiver 2 or the navigation system 3 is turned off ("YES" in step ST11), the broadcast receiving system 100 ends the process.

  While the display device 6 outputs the video and audio of the program in steps ST8 to ST9, the broadcast wave receiver 2 and the navigation system 3 perform a search for the broadcast wave in the background, and the broadcast reception system 100 performs the step. The processing of ST2 to ST6 and ST6a may be repeated at a predetermined time interval. The broadcast receiving system 100 updates the second list and the third list during the broadcast of the program, so that the time lag from when the program ends to when the second list and the third list are displayed on the display device 6 is shortened. can do. At the end of the program being viewed, the user can immediately select the broadcast station or distribution station to view the program next from the second list or the third list.

  In step ST9, even if the program has not ended, when the vehicle arrives at the destination and when the broadcasting station is switched by the user's operation, the broadcast receiving system 100 performs the processing in step ST10. It may be something that goes on.

  If no priority broadcast station is included in the first list in step ST5 and internet communication is not possible in step ST6a, the list creation unit 32 displays the first list as an exception in step ST7. It may be displayed on the device 6.

Next, an example of the second list created by the broadcast receiving system 100 will be described with reference to FIG.
In FIG. 3A, an arrow R connecting the starting point S and the destination G indicates the travel route of the vehicle M searched by the route search unit 31. An ellipse I indicates the broadcast area of the broadcast station A, and an ellipse II indicates the broadcast area of the broadcast station B. As shown in FIG. 3A, the entire travel route is included in the broadcast area of the broadcasting station A, but a part of the travel route near the destination G is out of the broadcast area of the broadcast station B.

  FIG. 3B shows the time change of the electric field intensity of the broadcast waves of the broadcasting stations A and B in the situation shown in FIG. The vehicle M stops at the departure point S at time t0. At this time, since the values of the electric field strengths Ea and Eb of the broadcast waves of the broadcast stations A and B both exceed the threshold Eth, the list creation unit 32 creates a first list including both the broadcast stations A and B. .

  Thereafter, from time t1 to t2, the electric field intensity Ea of the broadcasting station A temporarily falls below the threshold Eth due to the influence of buildings around the traveling route. From time t4 to time t5 when the vehicle arrives at the destination G, the travel route deviates from the broadcast area of the broadcast station B, so the electric field strength Eb of the broadcast station B fluctuates and becomes intermittently below the threshold Eth.

  That is, when the broadcast programs of the broadcast stations A and B are both switched at time t3, only the broadcast station B has priority among the broadcast stations A and B included in the first list in the time period from time t0 to time t3. Become a broadcasting station. On the other hand, in the time period from time t3 to time t5, only the broadcasting station A among the broadcasting stations A and B is the priority broadcasting station.

  Therefore, the list created by the list creation unit 32 at the time t0 at the time of route search is the second list in which the broadcasting station B is rearranged higher than the broadcasting station A as shown in FIG. On the other hand, at time t3, the list created by the list creating unit 32 at the end of the program is a second list in which the broadcasting station A is rearranged higher than the broadcasting station B as shown in FIG.

Next, an example of the third list created by the broadcast receiving system 100 will be described with reference to FIG.
In FIG. 4A, an ellipse II indicates the broadcasting area of the broadcasting station B as in FIG. 3A, and an ellipse III indicates the broadcasting area of the broadcasting station C. As shown in FIG. 4A, a part of the travel route near the destination G is out of the broadcast area of the broadcast station B and the broadcast station C.

  FIG. 4B shows a change over time of the electric field strength of the broadcast waves of the broadcasting stations B and C in the situation shown in FIG. The vehicle M stops at the departure point S at time t0. At this time, since the values of the electric field strengths Eb and Ec of the broadcast waves of the broadcasting stations B and C both exceed the threshold Eth, the list creation unit 32 creates a first list including both the broadcasting stations B and C. .

  From time t0 to time t3, the values of the electric field strengths Eb and Ec of the broadcast waves of the broadcasting stations B and C always exceed the threshold Eth. Therefore, at time t0, the list created by the list creation unit 32 at the time of route search is the second list in which the broadcasting stations B and C are rearranged higher than the remaining broadcasting stations as shown in FIG. .

  On the other hand, from time t4 to time t5, since the travel route is out of the broadcasting areas of both broadcasting stations B and C, the values of the electric field strengths Eb and Ec of the broadcasting stations B and C fluctuate and intermittently fall below the threshold Eth. Become. Therefore, at time t3 when both programs are switched, the list created by the list creation unit 32 at the end of the program is broadcasted by the Internet radio program distribution station D and the home broadcast receiver 11 as shown in FIG. The third list includes the receivable broadcasting station E.

  In addition, the mobile body carrying the broadcast receiving system 100 is not limited to a vehicle. It is good also as what is mounted in arbitrary moving bodies including a railroad, a ship, an aircraft, etc.

  The broadcast wave receiver 2 may receive only one of the broadcast waves of the television and the radio.

  The Internet module 5 may have only one of the Internet program receiving unit 52 and the home program receiving unit 53.

  Further, the Internet program receiving unit 52 may communicate with a moving image distribution server that distributes a moving image of a program instead of or in addition to the radio distribution server 10. In this case, the Internet program receiving unit 52 receives video / audio data and program information of a program distributed by the moving image distribution server from the moving image distribution server. The list creation unit 32 creates a third list including a moving image distribution station. The display device 6 outputs the video / audio data of the video received from the video distribution server as video and audio.

  The home program receiving unit 53 may communicate with a home broadcast recording device such as a television recorder installed at the user's home instead of the home broadcast receiving device 11. Alternatively, the home program receiving unit 53 may communicate with both the home broadcast receiving device 11 and the home broadcast recording device. In this case, the list creation unit 32 creates a third list including broadcast stations on which programs are recorded on the home broadcast recording device. The display device 6 outputs video and audio data of a recorded program received by the home program receiving unit 53 from the home broadcast recording device as video and audio.

  Moreover, the broadcast receiving apparatus with which the home program receiving part 53 communicates is not limited to the home broadcast receiving apparatus 11 installed in the user's home. As long as the video / audio data and program information included in the received broadcast wave are transmitted to the broadcast receiving system 100 via the Internet line network 8, it may be installed at any location outside the moving body.

  Similarly, the broadcast recording apparatus with which the home program receiving unit 53 communicates is not limited to the home broadcast recording apparatus installed at the user's home. As long as the video / audio data and program information of the recorded program are transmitted to the broadcast receiving system 100 via the Internet line network 8, the program may be installed at any place outside the moving body.

And a list creation unit 32 for creating a third list including possible program distribution stations.
If there is no priority broadcast station included in the first list, the third list including broadcast stations capable of receiving broadcast waves by the Internet radio distribution station or the home broadcast receiving device 11 is broadcasted. Even on a travel route where there is no broadcasting station capable of stably receiving waves, it is possible to preferentially select programs that can be viewed without interruption within a range where Internet communication is possible. In other words, even when there is no broadcasting station whose reception state is stable until the broadcast end time of the program, the user can preferentially select a program that is highly likely to be viewed stably until the broadcast end time.

  In addition, the list creating unit 32 broadcasts the received broadcast wave program to the broadcast receiving system 100 via the Internet line network 8 when the priority broadcast station is not included in the first list. A third list including a broadcasting station that can receive waves or a broadcasting station that has recorded a program with a broadcast recording apparatus outside the moving body that transmits a recorded program to the broadcast receiving system 100 via the Internet network 8 is created. By increasing the types of programs included in the third list, it is possible to increase user options.
