As shown in the block diagram of FIG. 1, the in-vehicle receiving apparatus 100 of the present invention is based on the premise that one tuner is used for both viewing multimedia broadcasts and receiving VICS information.

  The in-vehicle receiving device 100 can connect the diversity antenna 1 as an external device. The on-vehicle receiving device 100 includes at least a tuner 11 (= broadcast receiving unit), a demodulating unit 12 (= broadcast receiving unit), an HDD 13 (= recording unit), a CPU 14, a RAM 15, a ROM 16, an audio filter 17, an audio decoder 18, and a video. A filter 19, a video decoder 20, a data filter 21, a data decoder 22, an output unit 23, an accumulated data filter 24 (= VICS receiving unit), and an operation input unit 25 are provided.

  The tuner 11 receives a terrestrial digital broadcast signal from the diversity antenna 1 and selects a channel on a desired physical channel (= frequency band). Further, the tuner 11 monitors whether or not broadcast waves can be received on the selected physical channel. Specifically, for example, when a vehicle equipped with the in-vehicle receiving device 100 straddles a reception area or the like and the electric field intensity of the broadcast wave received so far falls below a predetermined threshold, it is considered that reception is impossible. .

  The demodulator 12 demodulates and error-corrects the selected signal input from the tuner 11 and outputs respective TSs of one segment and 12 segments. The TS demodulated by the demodulator 12 is given to an audio filter 17, a video filter 19, a data filter 21, and a stored data filter 24 described later.

  The RAM 15 is a readable / writable recording medium used for a work memory of the CPU 14.

  The ROM 16 is a read-only recording medium that stores a control program executed by the CPU 14.

  The audio filter 17 extracts only audio data from the TS output from the demodulator 12. The audio decoder 18 decodes the extracted audio data to generate a digital audio signal, and provides it to the output unit 23 described later.

  The video filter 19 extracts only video data from the TS output from the demodulator 12. The video decoder 20 decodes the extracted video data to generate a digital image signal, and provides it to the output unit 23 described later.

  The data filter 21 extracts data such as transmission parameters, NIT (Network Information Table), program information, and the like from the TS output from the demodulator 12. The data decoder 22 decodes the extracted data. The decrypted data is recorded in the HDD 13, RAM 15 or the like.

<2. About the configuration of the function section>
Here, the relationship among the functional units for performing the storage process and the reproduction control process according to the embodiment of the present invention will be described with reference to the functional block diagram of FIG. In FIG. 2, the functional blocks illustrated inside the CPU 14 represent functional units realized by the CPU 14 executing a predetermined program.

  As shown in FIG. 2, the accumulation process and the reproduction control process of the present embodiment are performed by the search unit 14a, the navigation unit 14b, and the VICS control unit 14c.

  The search unit 14a performs a search process for trying to receive a predetermined broadcast wave. The search unit 14a analyzes the receivable frequency band and uses the broadcast station information table (= related information) shown in FIG. 3 to determine the broadcast wave that the software provider instructed by the user distributes information. Attempt to receive.

  When reception is successful, reception of this broadcast wave is started. If reception fails, the search unit 14a attempts to receive a broadcast wave using an unchecked search frequency included in the broadcast station information table.

  FIG. 3 is a table showing an example of the broadcast station information table referred to by the search unit 14a. The broadcast station information table is a table in which search frequencies to be searched for each software provider are associated with each other. In the example of FIG. 3, it is assumed that the software provider is uniquely determined by the value of service_id and that the service_id can be received in the current region.

  However, a form may be used in which only a search target frequency is managed without having service_id. The search frequency is acquired from the NIT of the broadcast wave, but may be acquired through communication if it can be acquired through wireless communication or the like.

  In V-Low multimedia broadcasting, it is possible to distinguish between a real-time broadcasting service and a storage broadcasting service for each service_id from the value of service_id, NIT, and the like. For this reason, in such a broadcast form, information indicating whether or not the service is a storage type service may be included in the frequency information management table.

  For example, when the search unit 14a detects that the broadcast station information table is in the state shown in FIG. 3 and the software provider with the service ID = 0x2400 is selected by the user, the search frequency is 92.00 MHz or 98.00 MHz. Perform a search using.

  When reception is successful by the search, reception of this broadcast wave is started. If reception fails, the search unit 14a attempts to receive a broadcast wave using an unchecked frequency band included in the channel selection candidate table.

  The navigation unit 14b acquires position information indicating the current position, traveling direction, and the like of the in-vehicle receiving device 100 from a GPS device (not shown) and the like, and an image signal for displaying a map image showing the periphery of the in-vehicle receiving device 100 And output from the output unit 23.

  The navigation unit 14b receives designation of a destination from the user, and displays various information for route guidance on the map image. For example, an arrow indicating the guidance direction is displayed, or highlighting is performed to change the color of the guidance route. The navigation unit 14b displays such information using image information recorded in advance in the HDD 13 or the like and VICS information obtained from the stored data filter 24.

The VICS control unit 14c determines a frequency band in which the VICS information can be received when a predetermined operation is instructed to the navigation unit 14b during multimedia broadcast reception, for example, when a display of a navigation screen is instructed. To do. Then, the demodulation unit 12 and the search unit 14a are controlled so as to receive the VICS information in the determined frequency band. Details of processing performed by the VICS control unit 14c will be described later.
<3. Reception control processing>
Here, the processing flow of the reception control processing performed by the in-vehicle receiving device 100 according to the embodiment of the present invention will be described with reference to the flowchart of FIG.

  The processing flow of this embodiment is started when the navigation function provided in the navigation unit 14b becomes the foreground. For example, when the navigation function operates in the background of the in-vehicle receiving apparatus 100 and multimedia broadcasting is received in the foreground, the process is started when the navigation screen is changed.

  As the timing when the navigation function becomes the foreground, for example, when a navigation screen display instruction by a user operation is detected, or when a vehicle on which the in-vehicle receiving device 100 is mounted reaches an intersection or the like, route guidance This may be the case when the need arises.

  In the present embodiment, the following description will be given by taking as an example a case where an instruction to display a navigation screen by a user operation is detected.

  After the start of this process, in step S110, the VICS control unit 14c determines whether the VICS information can be received in the receiving frequency band. When the VICS information can be received at the receiving frequency, the navigation unit 14b is instructed to continue the reception of the multimedia broadcast and display the navigation screen reflecting the VICS information, and the process is terminated.

  When the VICS information cannot be received in the receiving frequency band, the VICS control unit 14c generates save information indicating the receiving frequency band and service_id in step S120, and records it in the RAM 15 or the like. The evacuation information is used to return to the original frequency band when the navigation screen transitions again to the multimedia broadcast screen, or when reception of VICS information fails.

  Next, in step S130, the VICS control unit 14c refers to the broadcast station information table of FIG. 3 and determines whether there is an unsearched frequency band.

  If there is no unsearched frequency band, in step S131, the VICS control unit 14c returns the received frequency band and service_id to those before the change by referring to the save information, and then ends this process. In this case, it is assumed that the VICS information cannot be received in the current region, and the navigation unit 14b is instructed to display the navigation screen without the VICS information.

  If there is an unsearched frequency band, in step S140, the VICS control unit 14c determines the frequency band to be searched from the broadcast station information table, and instructs the search unit 14a to perform the search. In this case, when a frequency band with a track record of receiving VICS information in the past is known, an embodiment in which the frequency band is preferentially searched may be used.

  Next, in step S150, the VICS control unit 14c determines whether the VICS information has been successfully received in the searched frequency band. If unsuccessful, the process again proceeds to step S130, and the search is continued.

If the reception of the VICS information is successful, the navigation unit 14b is instructed to display the navigation screen reflecting the received VICS information, and this process is terminated.
<4. Reception control processing during recording / recording / storage>
Here, a processing flow of reception control processing during recording / recording / accumulation performed by the in-vehicle receiving device 100 according to the embodiment of the present invention will be described with reference to the flowchart of FIG.

  The processing flow of FIG. 4 described above is a control flow of performing a search when VICS information cannot be received in the receiving frequency band when a navigation screen display instruction is detected.

  However, when the navigation screen is displayed during recording / recording / accumulating, it may be desired to prioritize recording / recording / accumulating over reception of VICS information. Therefore, when an instruction to display the navigation screen is detected during recording / recording / accumulation, first, the control flow of FIG. 5 is performed. That is, FIG. 5 is positioned as the pre-processing of FIG.

  The reception control process shown in FIG. 5 is started when the navigation function of the navigation unit 14b becomes the foreground during the reception of the multimedia broadcast.

  In step S210, the VICS control unit 14c determines whether the recording / recording / accumulation process by the demodulation unit 12 and the accumulation data filter 24 is being performed. If not, the process proceeds to the search process shown in FIG.

  If it is in progress, the VICS control unit 14c notifies that recording / recording / accumulation processing is being performed in step S220 by displaying a predetermined notification screen. For example, notification is performed by displaying a notification screen 90 shown in FIG. The notification screen 90 includes a cursor 91. The user can select whether to interrupt the recording / recording / accumulating process by operating the cursor 91 by operating the operation input unit 25. When the interruption is instructed, the process proceeds to the search process shown in FIG.

  Further, when displaying the notification screen 90, the VICS control unit 14c investigates the rebroadcast date and time of the multimedia broadcast program (= content) being recorded / recorded / accumulated, and displays it on the notification screen 90.

  The rebroadcast date and time is obtained from an EIT (Event Information Table) or the like. Alternatively, in the case where acquisition is possible through wireless communication or the like, an embodiment in which the rebroadcast date and time is acquired through wireless communication may be used. Further, when the rebroadcast date and time of the same program is notified in advance as in the case of V-Low multimedia broadcast, the rebroadcast date and time may be recorded in advance in a rebroadcast management table (not shown).

  Next, in step S230, the VICS control unit 14c branches the process depending on whether or not there is a rebroadcast schedule. When there is no rebroadcast schedule, the recording / recording / accumulation process is continued, and therefore the acquisition of VICS information is not attempted, and thus this process is terminated.

  If there is a rebroadcast schedule, the recording / recording / accumulation process is interrupted and the process proceeds to the search process shown in FIG. At this time, the user may select whether or not to make a recording / recording / accumulation reservation at the rebroadcast date and time.

  According to the present embodiment described above, when the navigation function is switched to the foreground during reception of the multimedia broadcast, the frequency band in which the VICS information is transmitted is searched to try to receive the VICS information. For this reason, for example, when switching from a display screen of a broadcast program to a navigation screen, it is possible to automatically acquire VICS information and reflect it on the navigation screen without requiring a user operation.

Also, when the navigation function is switched to the foreground during the recording / recording / accumulation process, the rebroadcast date and time of the program being recorded / recorded / accumulated is searched, and only when the rebroadcast is scheduled Attempt to receive VICS information. For this reason, even if the recording / recording / accumulation process is interrupted due to the reception of VICS information, the recording / recording / accumulation process can be performed using rebroadcast, so that the convenience of the user can be improved.
