In this case, the remote recording reservation icon is not displayed (step S4A).

When the remote recording reservation icon is displayed, the control unit 100 waits for a remote recording reservation request from the user (step S5A). When the user operates the remote recording reservation icon via the operation unit (step S6A: YES), the control unit 100 is notified as a remote recording reservation request, and the control unit 100 performs the recording reservation management selected by the user in the initial setting. In order to connect to the server 31, the process proceeds to step S7A.
On the other hand, when the data communication card 52 is not operating normally (step S7A: NO), the control unit 100 performs a user notification process that displays “Please retry after checking the data communication card” ( Step S31A), the WEB browser is closed, and the process proceeds to Step S5A. Further, in the case of communication connection NG (step S9A: NG), the control unit 100 performs a user notification process for displaying “Currently unable to connect to the recording reservation management server” (step S32A), closes the WEB browser, and performs step The process proceeds to S5A.

If it is determined in step S7A that the data communication card 52 is operating normally (step S7A: YES), the control unit 100 activates a WEB browser and the URL of the recording reservation management server 31 acquired by the initial setting ( Remote communication reservation URL) is used for communication connection (step S8A), and if the communication connection is OK (step S9A: OK), the login screen is connected, so the ID and password are set by the autocomplete (automatic input) function. Is automatically input and focused on the login button (step S10A).
In this manner, when the remote recording reservation icon is operated, a login screen for remote recording reservation is guided, and when the user operates the login button via the operation unit 64, the user can easily log in. For this reason, the user can perform recording settings in the recording reservation management server 31 via the in-vehicle broadcast receiving device 50 and perform recording settings for the recording device 21 owned at home.
When the user logs out after setting the recording (step S11A) and closes the WEB browser, the control unit 100 automatically returns to the original display screen (the screen on which the original TV program or electronic program that was viewed was displayed) ( Step S12A), waiting for reception of a reservation result confirmation mail (step S13A).

The reservation result confirmation e-mail is an e-mail that describes information such as whether or not the reservation is successful and information such as the reservation contents to the destination registered in advance when the recording reservation management server 31 is set to record. It is. In the recording reservation management server 31, the mail is sent to the in-vehicle broadcast receiving device 50 in advance, so that the mail is sent to the in-vehicle broadcast receiving device 50.
In the in-vehicle broadcast receiving device 50, the control unit 100 receives the reservation result confirmation mail (step S14A), analyzes the mail content (step S15A), and determines whether the recording reservation is successful or unsuccessful by voice synthesis processing. A notification process for notifying the user by output or video output is performed.
Specifically, if the result of analyzing the mail content is that the reservation is successful (step S16A: YES), the control unit 100 notifies the user of the success by audio output or video output (step S17A), and makes a reservation. If unsuccessful (step S16A: NO), the user is notified of the failure by audio output or video output (step S33A).

If the reservation is successful, the control unit 100 creates and stores a recording reservation list describing the reservation contents. Specifically, the control unit 100 determines whether or not reservation content information (for example, a recorded program channel, broadcast date and time, program name, etc.) is described in the reservation result confirmation email (step S18A). If it is described (step S18A: YES), the reservation content information in the mail is added to the pre-defined recording reservation list (step S19A). If not described (step S18A: NO), the control unit The reservation contents (in this embodiment, reservation date and time) within a range that 100 can be acquired are added to the recording reservation list (step S34A).
This recording reservation list can be read out by the control unit 100 in accordance with a user instruction and displayed on the display 67, whereby the user can check a list of recording reservations.
It should be noted that after execution of the processes in steps S19A, 34A, and 33A, the process shifts to the standby state of the remote recording reservation request in step S5A. The above is the operation of the remote recording reservation function (normal time). According to this, the user can easily make a remote recording reservation for the recording device 21 at home when there is a program that he / she wants to record in the car while he is out.

Next, the remote recording reservation function (during printing) processing (remote recording reservation process during printing) of the in-vehicle broadcast receiver 50 will be described.
This process includes a print-permitted content monitoring process that starts a print-recording reservation task when there is print-permitted content during digital broadcast data broadcast playback, and a print-recording reservation task process that is started by the print-permitted content monitoring process There is. These processes are executed when the remote recording reservation function (during printing) is “ON”, and the remote recording reservation function (during printing) is set to “ON”.
FIG. 9 is a flowchart showing the flow of print permission content monitoring processing.
This print-permitted content monitoring process is executed when the user selects a channel via the operation unit 64 during the reproduction of digital broadcast program data (when the user is watching the program) or when the next program is started. The
First, the control unit 100 acquires data of the data broadcast at the time of channel selection or transition to the next program (step S1C), and the user starts (reproduces) the data broadcast via the operation unit 64 (so-called “d”). If there is a button operation (step S2C), the BML browser is activated (step S3C), and the BML browser executes an ECMA script describing the browser operation in the acquired data in accordance with the user's instruction. Control is executed according to the flow of control statements described in the script.

The control unit 100 determines whether or not the in-vehicle broadcast receiving device (receiver) 50 has received an inquiry to investigate the presence or absence of the printing function during the execution of the control of the BML browser (step S5C). More specifically, it is confirmed whether or not the ECMA script includes the following function call for investigating the function incorporated in the browser (receiver).
Function: getBrowserSupport (sProvider, functionname, additionalinfo)
Argument specification: functionname = APIGroup, additionalinfo = Print. Basic
The above argument designation asks whether the browser (receiver) supports the extended function, and checks whether the print function is supported. If there is a call to the function, the process proceeds to the subsequent step S6C. If there is no call, the process proceeds to a process in step S4C.

In step S6C, since the in-vehicle broadcast receiving device 50 does not support the print function, the control unit 100 returns that fact to the BML browser. In this case, according to the ARIB convention, “1” is returned when the print function is supported, and “0” is returned when the print function is not supported. Therefore, “0” is returned. .
Further, it is understood that the print broadcast content is included in the data broadcast because of an inquiry for checking the presence of the print function, and the control unit 100 notifies the control unit 100 to that effect from the BML browser. , It is possible to detect that print permission content is included. As a result, the control unit 100 functions as a monitoring unit that monitors whether print permitted content is included.

In this case, since the return value of the BML browser is “0” (not compatible with the print function), the print button is not displayed according to the control statement of the ECMA script, or the fact that the print is not supported is displayed on the browser screen, and the ECMA The subsequent control is executed according to the script (step S7C).
The control unit 100 confirms the initial setting (setting information) of the remote recording reservation function (during printing) (step S8C). If the remote recording reservation function (during printing) is “ON” (step S9C: ON), The recording reservation task for printing is activated (step S10C).
On the other hand, if the remote recording reservation function (during printing) is “OFF” (step S9C: OFF), the control unit 100 does not activate the recording reservation task for printing (step S11C).

FIG. 10 and FIG. 11 are flowcharts showing the flow after the start of the print recording reservation task.
As shown in this figure, the control unit 100 first displays a remote recording reservation (print) icon (hereinafter referred to as a print icon as appropriate) on the screen task tray (step S1D), and remote recording reservation (printing) from the user. ) Wait for the request (step S2D). When the user operates the print icon via the operation unit (step S3D: YES), the control unit 100 is notified as a remote recording reservation (printing) request, and the control unit 100 selects the recording reservation selected by the user in the initial setting. In order to connect to the management server, the process proceeds to step S10D.
Here, when the user does not operate the print icon (step S3D: NO), the control unit 100 proceeds to the process of step S2D if the currently received program is before the end (step S4D: NO), If the currently received program ends (step S4D: YES), the print icon is hidden and the recording reservation task for printing ends.

  Further, when the data communication card 52 is not operating normally (step S10D: NO), the control unit 100 performs a user notification process for displaying “Please retry after checking the data communication card” ( In step S31D, the WEB browser is closed and the process proceeds to step S2A. In addition, in the case of communication connection NG (step S12D: NG), a user notification process that displays “currently unable to connect to the recording reservation management server” is performed. (Step S32A), the WEB browser is closed, and the process proceeds to step S5A.

In the process of step S10D, the control unit 100 determines whether or not the data communication card 52 is operating normally. If the data communication card 52 is operating normally (step S10D: YES), the control unit 100 starts the WEB browser and performs initial setting. Communication connection is performed using the site URL of the recording reservation management server 31 specified in (Step S11D). If the communication connection is OK (Step S12D: OK), the login screen is connected, so autocomplete (automatic input) ) The function automatically inputs the ID and password and focuses on the login button (step S13D).
In this case, the control unit 100 displays “Connect to the remote recording reservation service site. If connection is established, log in and make a recording reservation” to prompt the user to log in. In this way, when the print icon is operated, the login screen for remote recording reservation is guided, and when the user operates the login button via the operation unit 64, the user can log in easily.

When logged in, the control unit 100 identifies the program being viewed on the receiving device 50 based on the status information holding the operation state information of the in-vehicle broadcast receiving device 50, and the recording reservation management server 31 using the WEB browser. On the other hand, for the recorded program selection item, the currently viewed program is auto-selected from the program table, and for the recording mode selection item, the TS recording mode is auto-selected, and the recording reservation execution button is focused (step S14D).
Subsequently, after the user operates the recording reservation execution button, when the recording reservation management server 31 accepts the recording reservation job, the logout button is focused by the WEB browser (step S15D), and the logout button is operated by the user. The control unit 100 closes the WEB browser, automatically returns to the original display screen (screen displaying the TV program or electronic program that was being viewed) (step S16D), and waits for reception of the reservation result confirmation mail (step S17D). ).

Then, when receiving the reservation result confirmation mail (step S18D), the control unit 100 analyzes the mail contents (step S19D), and determines whether the recording reservation is successful or not by voice output or video output by voice synthesis processing. A notification process for notifying the user is performed.
Specifically, if the result of analyzing the mail content is that the reservation is successful (step S20D: YES), the control unit 100 notifies the user of the success by audio output or video output (step S21D), and makes a reservation. If unsuccessful (step S20D: NO), the user is notified of the failure through audio output or video output (step S33D).

  If the reservation is successful, the control unit 100 performs processing for adding the reservation content to the remote recording reservation list (step S22D). This process is the same as the process of steps S18A, S19A, and S34A described above. That is, the control unit 100 stores information on reservation contents (for example, recorded program channel, broadcast date and time, program name, etc.) in the reservation result confirmation mail. ) Is described (step S18A), and if it is described, the reservation content information in the mail is added to the pre-defined recording reservation list (step S19A) and must be described. For example, reservation contents within the range that can be acquired by the control unit 100 (in this embodiment, reservation date and time) are added to the recording reservation list (step S34A).

Further, the control unit 100 hides the print icon displayed on the screen task tray, and switches to the home recording operation icon so as to notify the user that recording is being performed at home (home recording operation is being performed). (Step S23D).
When broadcast of the reserved program ends, the control unit 100 hides the home recording operation icon and displays the home recording end icon to notify the user that home recording has ended (home recording has ended). The display is switched, and the home recording end icon is hidden when a predetermined time elapses. The above is the operation after starting the recording reservation task for printing. That is, in the present embodiment, the remote recording control unit that performs the recording setting of the recording device 21 installed outside the vehicle is configured by the cooperative operation of the components such as the control unit 100 and the data communication card 52.

  As described above, the in-vehicle broadcast receiving device 50 according to the present embodiment monitors whether or not print permitted content is included during reproduction of a digital broadcast data broadcast. Since the recording apparatus 21 is guided to the remote recording reservation, the program including the print permitted content can be remotely recorded. Therefore, the user can print out from the printer 25 by playing back the program recorded by the remote recording device 21 to start data broadcasting and operating the print button on the browser screen. Therefore, it is possible to eliminate the inconvenience of the user in the vehicle that cannot be printed on the spot when there is a print permission content in the data broadcast.

Moreover, in the present embodiment, the program including the print-permitted content and the recording mode (TS recording mode) are automatically set at the time of remote recording, so that the print-permitted content can be surely recorded so as to be printable.
In addition, the in-vehicle broadcast receiving device 50 displays a remote recording reservation (print) icon and allows the user to select whether or not to perform recording when print permission content is included, so that the program desired by the user can be accurately selected. It is possible to record and appropriately reflect the user's will.
The in-vehicle broadcast receiving apparatus 50 stores setting information describing whether the function for recording data broadcasts including print-permitted content is ON (valid) or OFF (invalid), and only when the function is ON (valid). Since the recording setting of the data broadcast including the print permitted content is performed, the function can be turned ON / OFF.

Furthermore, since the in-vehicle broadcast receiving apparatus 50 performs data communication with the recording reservation management server 31 and sets recording in the recording apparatus 21, recording is performed using the existing remote recording compatible recording apparatus 21 and recording reservation management server 31. can do.
The in-vehicle broadcast receiving apparatus 50 receives the reservation result confirmation mail transmitted from the recording reservation management server 31 and analyzes the reservation result confirmation mail to notify whether or not the recording can be set by audio output or video output. Therefore, it can be easily known whether or not the user can set the recording. In this case, under the control of the control unit 100, a configuration for performing voice notification through the speaker 92 and a configuration for performing video notification through the display 67 function as the notification unit.

Second Embodiment
In the second embodiment, print permission content monitoring processing is different. In this print-permitted content monitoring process, when digital broadcast program data is being reproduced, whether or not print-permitted content is included in the data broadcast is prefetched.
FIG. 12 is a flowchart showing the flow of print permission content monitoring processing.
This print-permitted content monitoring process is executed when the user selects the digital television mode, receives the terrestrial digital broadcast with the in-vehicle broadcast receiving device 50, and starts reproducing the program data.
First, the control unit 100 acquires data of data broadcast at the time of channel selection or transition to the next program (step S1E), and when the data broadcast is not started during program data reproduction, the BML browser is set to the data broadcast. Is started in a pre-reading mode (back mode) for analyzing (step S2E), and pre-reading of data broadcasting (data analysis of ECMA script or the like) is performed while program data is being reproduced (step S3E).

When acquiring the analysis result of the BML browser (step S4E), the control unit 100 ends the prefetch mode of the BML browser (step S5E), decodes the analysis result (step S6E), and the print permission content is included in the data broadcast. It is determined whether or not (step S7E).
Next, when the data broadcast includes print-permitted content (step S7E: YES), the control unit 100 checks the initial setting (setting information) of the remote recording reservation function (during printing) (step S8E), and the remote If the recording reservation function (during printing) is “ON” (step S9E: ON), the recording reservation task for printing is activated (step S10E).
On the other hand, when the print permission content is not included in the data broadcast (step S7E: NO) and the remote recording reservation function (during printing) is “OFF” (step S9E: OFF), the control unit 100 The recording reservation task for printing is not activated (step S11E). The print permission content monitoring process is as described above, and the recording reservation task for printing is the same as in the first embodiment.

According to the present embodiment, when program data is being reproduced, it is determined whether or not there is a print-permitted content by prefetching the data broadcast. Users can be notified immediately when content is available. For this reason, the time from the notification start to the user (that is, the display start of the print icon) to the end of the program can be increased, and the grace period for the remote recording reservation to be given to the user can be lengthened. The probability of failure can be lowered.
In addition, when this pre-read notification method is used, the remote recording reservation (print) icon can be displayed to notify the user viewing the program that there is print-permitted content. You can encourage them to view the broadcast.

  Each of the above-described embodiments is merely one aspect of the present invention, and can be arbitrarily modified within the scope of the present invention. For example, in each of the above-described embodiments, the present invention is applied to the in-vehicle broadcast receiving device 50. However, the present invention is widely applied to non-printable data broadcast receiving devices such as an in-vehicle device such as a car navigation device having a TV function. Also good.
