  The reproduction processing unit 12 executes processing necessary for reproducing music and video according to the program table created by the program table creating unit 11. The route search unit 13 uses the map data stored in the map data storage unit 15 to perform a route search for searching for a travel guide route indicating a route to the destination according to the operation data 6d, and indicates the searched travel guide route. Route data is stored in the route data storage unit 14 to be described later.

  The data storage unit 3 includes an HDD (Hard Disk Drive), and includes a route data storage unit 14, a map data storage unit 15, a reproduction data storage unit 16, and a preference data storage unit 17.

  The route data storage unit 14 stores route data indicating the travel guide route searched by the route search unit 13 and current location data indicating the position of the vehicle on the travel guide route.

  The map data storage unit 15 stores map data. This map data is used for route search by the route search unit 13 and used when displaying a map on the display device 4.

  The reproduction data storage unit 16 is obtained by recording a radio broadcast or a television broadcast. The reproduction data storage unit 16 reproduces reproduction data for reproducing music or video or reproduction for reproducing music or video read from a recording medium D described later. Data is stored. The preference data storage unit 17 stores preference data indicating user preferences.

  The display device 4 includes a liquid crystal display panel, and displays a map, a travel guide route, a program guide, and the like. The display device 4 displays a message for prompting the user to perform an input operation and a message for explaining the content of the input operation.

  The broadcast receiving unit 5 selects and receives a desired broadcast wave from the broadcast waves captured by the antenna 5a, and extracts and outputs a broadcast signal 5d from the received broadcast wave. For example, the broadcast receiver 5 selects and receives AM and FM radio broadcasts and television broadcast waves.

  The input operation unit 6 has a plurality of operation buttons, and inputs operation data 6d to the ECU 2 when an input operation using the plurality of operation buttons is performed. The disk drive 7 reads recorded digital data from a recording medium D (for example, a CD (Compact Disc), an MD (Mini Disc), a DVD (Digital Versatile Disk), etc.) and reproduces music and video. Playback data 7d is output.

  Then, the operation | movement content of the program guide preparation apparatus 1 for vehicles which has the above structures is explained in full detail.

  In a vehicle in which the vehicle program guide creation device 1 is mounted, when the user designates reproduction from route guidance, the vehicle program guide creation device 1 operates according to the flowchart shown in FIG. Here, the reproduction from the route guidance is a program using EPG information obtained from broadcast waves that can be received in each area (scheduled running area) on the searched driving guidance route when the user instructs a route search. This means that a table is created and music and video are played according to the program table. FIG. 2 is a flowchart showing an operation procedure of reproduction processing from route guidance.

  When the vehicle program guide creation device 1 starts the reproduction process from the route guidance, in S1, the ECU 2 first displays a message for prompting the keyword input on the display device 4 to allow the user to input the keyword. The user operates the input operation unit 6 to input a desired keyword. Then, operation data 6 d (hereinafter referred to as “keyword data”) indicating the input keyword is input to the ECU 2. For example, the user can input a band name or a singer name for specifying the music to be listened to, and can also input a keyword (enka, rock, etc.) for specifying the genre of the music to be listened to. The keyword data 6d is stored in the preference data storage unit 17 as preference data indicating the user's preference.

  In subsequent S <b> 2, the ECU 2 acquires route data indicating the travel guide route searched by the route search unit 13 from the route data storage unit 14. Next, the ECU 2 proceeds to S3, and acquires EPG information corresponding to the keyword data 6d stored in the preference data storage unit 17 from the broadcast signal 5d obtained from the broadcast receiving unit 5. In continuing S4, the program schedule preparation part 11 of ECU2 act | operates, and produces a program schedule using the EPG information acquired by S4.

  Then, when the ECU 2 proceeds to S5, the ECU 2 performs an operation as a determination means, and determines whether or not there is a vacant time zone (referred to as a blank time zone, also referred to as a blank) in the program table created in S4 without a program being incorporated. If there is a blank time zone, the operation proceeds to S6, and if not, the operation proceeds to S8.

  The ECU 2 can determine the area on the travel guide route from the route data. Each area can be divided into a receivable area where the broadcast receiving unit 5 can receive broadcast waves or a non-receivable area where the broadcast receiving unit 5 cannot receive broadcast waves. Further, if the departure time is known, the time zone scheduled to travel in each area can be obtained. Of the obtained time zones, programs using EPG information are incorporated in the time zones corresponding to the receivable areas, but programs using EPG information are incorporated in the time zones corresponding to the incapable areas. Because it is not possible, it is a blank time zone.

  When the operation proceeds to S6, the program guide creation unit 11 of the ECU 2 operates, and the reproduction data corresponding to the keyword data 6d is acquired from the data storage unit 3 or the disk drive 7. In subsequent S7, the ECU 2 performs the operation as the program guide creation unit 11, and incorporates the program reproduced using the reproduction data acquired in S6 into the blank time zone as a reproduced program. In the present embodiment, a program guide in which a reproduction program is incorporated is referred to as an embedded program guide.

  In step S8, the ECU 2 performs an operation as the reproduction processing unit 12, reproduces music and video according to the created program guide, and then terminates reproduction processing from the route guidance.

  In the prior art, if there is an unreceivable area in the planned travel area, a blank is generated in the program guide. However, when there is an unreceivable area in the planned travel area, the vehicle program guide creation device 1 according to the present embodiment creates a built-in program guide in which a reproduction program is incorporated in a blank, so the program guide to be created Does not create a blank. Therefore, the vehicular program guide creation device 1 can continuously reproduce music and video based on the created program guide. Therefore, the user can enjoy music and video continuously without checking programs and switching the recording medium D. Since the reproduction program is incorporated only when there is an unreceivable area, real-time reproduction by reception of broadcast waves can be given priority over reproduction by reproduction data.

  In addition, since the reproduction program incorporated in the program guide corresponds to the keyword data 6d, the vehicle program guide creation device 1 creates a program guide that suits the user's preference even when the reproduction program is incorporated. Can do.

  The reproduction process from the route guidance can also be executed according to the flowchart shown in S3.

  The flowchart shown in FIG. 3 is different from the flowchart shown in FIG. 2 in that S10, S11, and S12 are included.

  Then, the ECU 2 proceeds to S10 following S2, and determines whether or not there is data corresponding to the keyword data 6d in the broadcast signal. When such data is present, the operation proceeds to S3 and S3 to S8 in FIG. If not, the operation proceeds to S11. In S11, reproduction data corresponding to the keyword data 6d is acquired from the data storage unit 3 or the disk drive 7, and in S12, the reproduction processing unit 12 reproduces a song or video using the acquired reproduction data, and then routes The reproduction process from the guide ends.

  Even in this case, as in the case of FIG. 2, the created program table has no blank space, so that music and video can be reproduced continuously. In the case of FIG. 3, if there is no data corresponding to the keyword data 6d in the broadcast signal 5d, the music or video is reproduced using the reproduction data. Therefore, even if the broadcast wave can be received in the planned travel area, if the broadcast signal 5d does not meet the user's preference, reproduction using the reproduction data is performed, so that music or video that matches the user's preference is reproduced. It can be done.

  The above description is the description of the embodiment of the present invention, and does not limit the apparatus and method of the present invention, and various modifications can be easily implemented. In addition, an apparatus or method configured by appropriately combining components, functions, features, or method steps in each embodiment is also included in the present invention.
