  As described above, the present invention can always automatically receive a program that matches the user's preference even when the automobile 2 equipped with the program receiving device 10 moves, so that it is possible to realize program reception suitable for a mobile object. The present invention is not limited to the above-described embodiment, and various modifications can be applied. For example, the program receiving apparatus 10 includes a terrestrial digital TV broadcast, a satellite digital TV broadcast, a VHF TV broadcast, a UHF TV broadcast, a satellite analog TV broadcast, an Internet TV broadcast, a terrestrial digital radio broadcast, a satellite digital radio broadcast, an AM shortwave radio broadcast, Any of AM medium wave radio broadcast, FM radio broadcast, satellite analog radio broadcast, and Internet radio broadcast may be received, and it is particularly preferable to be able to receive a plurality of broadcasts from the viewpoint of expanding the reception target. is there. Further, in response to the detection of the program reception status, the program receiving device 10 detects the intensity of the broadcast radio wave received by the broadcast receiving unit 11 or the intensity related to the reception of the communication unit 12, and sets the detected intensity to a certain threshold. If the current position is lower, it is possible to adopt a configuration in which it is determined that the current position is out of the program reception area.

  In addition, various wireless communication methods such as PHS, wireless LAN, and Bluetooth can be applied to the communication unit 12, and the relay base stations 6a to 6n with which the communication unit 12 communicates are specified, so that the program receiving device 10 A configuration for detecting the position can also be applied, and in such a configuration, the GPS receiver 16 can be omitted. In addition, the program management server 7 detects the position of the relay base stations 6a to 6n that communicate with the program receiving apparatus 10, so that the position of the automobile 2 (program receiving apparatus 10) is detected on the program management server 7 side. It may be. Moreover, you may utilize DSRC (Dedicated Short Range Communication) for the position detection of the motor vehicle 2 (program receiving device 10). Further, the program receiving apparatus 10 stores the input keyword, the received broadcast type, and the like in the recording unit 15, and specifies the keyword that is frequently used for search and the broadcast station that is frequently received for the search. In addition, it is possible to apply a configuration that automatically searches based on the search conditions of the broadcasting station and reduces the user's operation burden related to the search.

  Furthermore, the program receiving device 10 transmits only the position data related to the position detected by the GPS receiving unit 16 to the program management server 7, and the program management server 7 receives the latitude and longitude related to the transmitted position data. It is also possible to apply a configuration in which possible program guide data is created and transmitted. In this case, the program receiving apparatus 10 can acquire program guide data relating to all programs that can be received at the current position, create a program guide database from the program guide data, and perform a search using the input keywords and search conditions. become. Further, the program management server 7 only needs to create program guide data corresponding to the reception area, and processing for searching for a program corresponding to the search key becomes unnecessary, so the processing load is reduced.

  FIG. 9 is a third flowchart showing a processing procedure of a program receiving method according to a modification of the present invention. In the program receiving method according to this modification, the keyword and position are not transmitted from the program receiving device 10 installed in the automobile 2 shown in FIG. Program list data having information relating to a broadcast program is transmitted to the program receiving device 10, and the program receiving device 10 creates a program list database based on the transmitted program list data and searches the program list database. Do.

  Therefore, the program management server 7 of the modified example is a program that includes information relating to television broadcasts, AM radio broadcasts, FM radio broadcasts, and the like recorded on the hard disk 7b shown in FIG. Based on the data, program list data relating to all broadcasts for a required time of 6 hours and 1 day is created, and the program list data is appropriately transmitted to the outside. Further, in the program receiving apparatus 10 of the modified example, program list data is appropriately received by the communication unit 12 shown in FIG. 3, and a program list database corresponding to the search is created and recorded from the program list data received by the system control unit 14. The data is recorded in the part 15. When the keyword and the search condition are input and the position is detected by the GPS receiving unit 16, the system control unit 14 receives the program corresponding to the keyword from the program list database that can be received at the current position. The broadcast receiving unit 11 or the communication unit 12 receives the program corresponding to the search.

  Therefore, in the configuration of such a modified example, as shown in the third flowchart of FIG. 9, the program management server 7 transmits the program list data (S30), and the program receiving apparatus 10 creates the program list database (S31). ), Accepts keywords and search conditions (S32), detects the current position (S33), and searches the program list database for programs that match the user's preference and can be received at the current position (S33). S34). The processing after the search is basically the same processing procedure as that of the second flowchart of FIG. 8, but the following three points can be cited as different processing contents. In other words, after the display of not applicable (S12), the system waits for input of a new keyword. When a new keyword is received (S16: YES), a search is performed with a new keyword, and the current position is received. Searching for a receivable program at a new position when it is not within the possible area (S20: NO) is different from the process of the second flowchart.

  In the above-described modification, since no data is sent from the program receiving device 10 to the program management server 7, the program management server 7 is configured to transmit the program list data on the broadcast wave from the broadcasting device of the broadcasting station. It is also possible to do.

  In addition, as another program receiving method, the radio broadcast and satellite radio broadcast corresponding to the radio to be watched are used by adding the current song title, the next song title, etc. to the broadcast radio wave and transmitting it. It is also possible to search for programs that suit your preferences. In this modification, the program receiving apparatus 10 needs to newly provide a processing unit that converts the contents related to the characters of the broadcast radio wave received by the broadcast receiving unit 11 into searchable data. Also, in the process of this modification, a search is performed with the keyword input for the data converted by this processing unit, and if the search is applicable, the program is continuously received, and if not, the data can be received. Another broadcast program is received and searched. Therefore, in this modification, the program management server 7 can be dispensed with and the configuration of the entire system can be simplified.
