Hereinafter, embodiments of the present invention will be described with reference to the drawings.
A. Constitution
FIG. 1 is a block diagram showing an overall configuration of a navigation apparatus 10 according to an embodiment of the present invention. In this figure, the CPU 100 controls each part of the apparatus according to an operation event supplied from the operation unit 103. A characteristic processing operation of the CPU 100 according to the gist of the present invention will be described later. The ROM 101 stores various program data executed by the CPU 100. The various programs referred to here include broadcast recording processing and icon operation processing described later.

The RAM 102 includes a work area and a recording area. In the work area of the RAM 102, various registers and flag data used for the calculation of the CPU 100 are temporarily stored, as well as position information generated by the GPS signal receiving unit 105 to be described later, and text broadcasting of the program being recorded as will be described later. The address data extracted from is temporarily stored.

In the recording area of the RAM 102, under the control of the CPU 100, the broadcast data output from the digital broadcast receiving unit 106 is recorded in association with the recording attribute data representing the recording attribute. As shown in FIG. 2, the recording attribute data includes “reception channel”, “recording start date / time”, “recording time”, “title”, and “recording code”.

The title represents the program name extracted from the teletext of the recorded program, and the recording code represents the recording start address of the broadcast data in the recording area. In addition, a time code may be used instead of the recording start address. In short, the recording code may be of any type as long as it is information that can specify the recorded broadcast data.

The operation unit 103 includes a touch panel disposed on the display screen of the display unit 104 and various operation switches disposed on an operation panel (not shown), and generates an operation event corresponding to the touch operation or the switch operation. To supply to the CPU 100. For example, when a touch operation is performed on a touch panel corresponding to an icon displayed on the screen of the display unit 104, the CPU 100 executes a function assigned to the icon based on the touch operation event.

The display unit 104 displays the current position on the map according to the display control signal supplied from the CPU 100, and displays the result of route search as a guide. The GPS signal receiving unit 105 receives positioning radio waves from GPS satellites according to instructions from the CPU 100, and generates position information including at least the latitude and longitude of the current location. This position information is stored in the work area of the RAM 102.

  The digital broadcast receiving unit 106 outputs to the CPU 100 broadcast data obtained by receiving and demodulating a television broadcast signal of a reception channel in accordance with a channel selection instruction given from the CPU 100. Broadcast data includes teletext data. When a program recording is instructed by a user operation, the CPU 100 records the above-described recording attribute data in the recording area of the RAM 102 in association with the broadcast data output from the digital broadcast receiving unit 106.

  The route search destination storage unit 107 is extracted from addresses of main landmarks (for example, amusement parks and hotels) used as a destination for route search, and text broadcasts of recorded programs. The destination information indicating the address of the famous place or shop introduced in is stored. As shown in FIG. 3, the destination information includes “icon type”, “name”, “address”, and “attribute”.

In the destination information extracted from the recorded program, the above-described recording code is assigned as the attribute. By doing so, the destination information extracted from the recorded program is linked to the recorded broadcast data. The map database 108 stores and manages map data expressed in a vector format by dividing it into rectangular areas called meshes. Under the control of the CPU 100, the audio output unit 109 outputs guidance audio during navigation and outputs playback audio during recording and reproduction.

B. Operation Next, the operation of the navigation device 10 configured as described above will be described with reference to FIGS. Below, each operation | movement of the broadcast recording process and icon operation process which CPU100 performs is described.

(1) Operation of Broadcast Recording Process The operation of the broadcast recording process will be described with reference to FIG. FIG. 4 is a flowchart showing the operation of the broadcast recording process executed by the CPU 100. The reception channel to be recorded, the recording start date and time, and the recording time are set in advance by the user. When the set recording start date and time is reached, the CPU 100 proceeds to step SA1 shown in FIG. 4 and starts program recording. That is, the broadcast data output by receiving and demodulating by the digital broadcast receiving unit 106 is recorded in the recording area of the RAM 102 in association with the recording attribute data (reception channel set by the user, recording start date and time and recording time).

  Next, in step SA2, it is determined whether or not the program has ended. If the program is being broadcast, the determination result is “NO”, and the process proceeds to step SA3 to determine whether address data is included in the text broadcast of the program being recorded. If the address data is not included, the determination result is “NO”, and the process returns to step SA2. Thereafter, it is determined whether address data is included in the text broadcast until the program ends.

In this embodiment, the address data is extracted from the text broadcast of the program to be recorded. However, the present invention is not limited to this, and a mode in which a telephone number is extracted and converted into address data may be used. In addition, it is possible to adopt a mode in which address data is converted by extracting proper nouns representing place names.

  On the other hand, when it is detected that the address data is included in the teletext of the program being recorded, the determination result in step SA3 is “YES”, and the process proceeds to step SA4, where the address data is extracted from the teletext and the work in the RAM 102 is performed. After temporarily storing in the area, the process returns to step SA2.

When the program ends, the determination result in step SA2 is “YES”, and the process proceeds to step SA5, where the program name extracted from the text broadcast of the recorded program is used as the title in the recording attribute data and broadcast in the recording area of the RAM 102. The data recording start address is set for each recording code in the recording attribute data, and the recording ends.

  Next, in step SA6, the “icon type” indicating that the program is a recorded program, the title (program name) in the recording attribute data is “name”, and the address data extracted from the text broadcast of the recorded program is “address”. The destination information is registered in the route search destination storage unit 107. For example, when a program titled “Gourmet Trip” is recorded and address data is extracted from the teletext, the icon type is “Program” and the name is “Gourmet Trip” as shown in FIG. , ”The destination information of the address data“ Niwano-machi, Kamiina-gun, Nagano Prefecture ”extracted from the address is registered in the route search destination storage unit 107.

  When destination information including “icon type”, “name”, and “address” is registered in the route search destination storage unit 107 in this way, the process proceeds to step SA7, where “attribute” of the registered destination information is set. The “recording code 1” in the above-mentioned recording attribute data is assigned, thereby linking the destination information and the recorded broadcast data specified by the recording attribute data, and the process is finished.

  Thus, in the broadcast recording process, broadcast data of a program output from the digital broadcast receiving unit 106 is recorded, and address data is extracted from the character broadcast of the program. When the recording is completed, the program name extracted from the teletext is set as the title in the recording attribute data, and the recording start address of the broadcasting data in the recording area of the RAM 102 is set as the recording code in the recording attribute data. Then, the address data extracted from the teletext of the recorded program, the title (program name) in the recording attribute data, and the recording code are registered in the route search destination storage unit 107 as destination information.

(2) Operation of Icon Operation Processing Next, the operation of icon operation processing will be described with reference to FIG. FIG. 5 is a flowchart showing icon operation processing performed by the CPU 100. First, in step SB1, map data including position information (current position) generated by the GPS signal receiving unit 105 is searched from the map database 108, and a map including the current position is displayed on the display unit 104 based on the corresponding map data. .

  Next, in step SB2, a “route search destination icon” is displayed. The “route search destination icon” is an icon corresponding to each destination information registered in the route search destination storage unit 107. Therefore, a “route search destination icon” is displayed on the map displayed with reference to the address data in the destination information. The “route search destination icon” displays a menu icon for selecting either “recording / playback” or “route search” in response to a touch operation.

  Therefore, for example, after touching the “route search destination icon” of the destination information obtained from the recorded program to display a menu icon for selecting either “recording playback” or “route search”, the “route It is assumed that “Search” is touched. If it does so, it will progress to step SB4, will perform the route search process which searches the path | route from the present position to the destination with reference to the address in destination information, and in subsequent step SB5, from the present position obtained by the route search process. The route to the destination is displayed as a map and the process is finished.

  On the other hand, after touching the “Route Search Destination Icon” in the destination information obtained from the recorded program to display a menu icon for selecting either “Recording Playback” or “Route Search”, “Recording Playback” ”Is read out from the route search destination storage unit 107, the attribute“ recording code ”of the corresponding destination information is read, and the recording start address in the recording area of the RAM 102 represented by the read“ recording code ” Then, the recording / reproducing process for reproducing the recorded broadcast data is executed and the present process is completed.

  As described above, in this embodiment, broadcast data of a program output from the digital broadcast receiving unit 106 is recorded, and address data is extracted from the character broadcast of the program. When the recording is completed, the program name extracted from the teletext is set as the title in the recording attribute data, and the recording start address of the broadcasting data in the recording area of the RAM 102 is set as the recording code in the recording attribute data. The address data extracted from the teletext of the recorded program, the title (program name) in the recording attribute data, and the recording code are registered in the route search destination storage unit 107 as destination information.

  Then, a “route search destination icon” indicating the destination information registered in the route search destination storage unit 107 is displayed on the map, and the “route search destination icon” is touch-operated to perform “recording”. When a menu icon for selecting either “playback” or “route search” is displayed and then “recording playback” is touched, the attribute “recording code” of the corresponding destination information from the route search destination storage unit 107 is displayed. Since the recorded broadcast data is reproduced from the recording start address in the recording area of the RAM 102 represented by the read “recording code”, it is obtained from the broadcast program that was forgotten or missed and could not be viewed. You can see what the destination is.
