Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a broadcast receiving apparatus, and more particularly to a broadcast receiving apparatus mounted on a mobile body and acquiring broadcast contents while moving. The broadcast content (content) is, for example, the entire program or a part of the program. INDUSTRIAL APPLICABILITY The present invention is preferably applied to a digital broadcast receiving device having a program sequence information receiving function.

[0002]

2. Description of the Related Art As digital broadcasting, satellite broadcasting, terrestrial television broadcasting and terrestrial radio broadcasting are known. By mounting the broadcast receiving device on a moving body, a user can enjoy broadcasting and obtain useful information while moving. Development of mobile digital music broadcasting for practical use is progressing.

[0003]

[Problems to be Solved by the Invention] Here, "moving body"
The conventional problem will be described by taking "vehicle" as "" and "program" as "broadcast content (content)".

When a vehicle receives a broadcast program, a situation may occur in which the vehicle arrives at the destination but the program is not yet finished, that is, the program reception is not completed while the vehicle is moving. The reason why such a situation occurs is that the user is not provided with a clue to select a program that ends before reaching the destination.

Of course, if the user diligently checks the program information and the moving schedule, it is possible to find a program that can be viewed to the end with a certain probability. However, it is very troublesome for the user of the vehicle to check the program during driving at each driving and match it with his / her moving schedule.

For daily commuting, the user can select a program that ends during commuting. However, this is just a special case of watching a fixed program at a fixed time every day.

As a result of the situation where the program reception is not completed while moving as described above, the user cannot enjoy the program to the end or cannot obtain necessary information. Or you will have to spend time wasting your time glued to the car to watch the show to the end. Particularly in digital broadcasting, it is possible to download data such as music and programs toward a receiving device during a program. In such programs, it is desirable to avoid the situation where reception cannot be completed.

The present invention has been made in view of the above problems, and one of the main objects thereof is to be able to select the broadcast contents which can be received completely while moving.

[0009]

To achieve the above object, a mobile broadcast receiving apparatus of the present invention comprises a receiving means for receiving broadcast contents and incidental information indicating a broadcast end time of the broadcast contents, The navigation device is used as the planned travel time of the mobile unit.
Scheduled travel time acquisition means for acquiring the estimated arrival time estimated by the device, the broadcast end time and the estimated arrival time
A determination means for determining whether or not the reception of the broadcast contents can be completed while moving, and a broadcast for which the reception can be completed.
Judgment by the judgment means in order to facilitate reception of contents
And reception completion promoting means for notifying the user of the result of the above .

Here, "broadcast content (content)" is
Video and audio of TV programs, audio of radio broadcasts, music of music broadcasts, etc. The broadcast content is, for example, the entire broadcast program or a part of the broadcast program (each song of a music program, etc.). The “additional information” sent together with the broadcast contents is, for example, program arrangement information of digital broadcasting. The “planned travel time” is estimated according to the travel time estimation technique of the navigation device, for example.

As described above, according to the present invention, it is determined whether or not the reception of the broadcast content can be completed, and the reception of the broadcast that can be completed is promoted based on the result of the determination. It is possible to receive a program that can be completed and complete the reception before the end of the movement.

The appropriate reception completion promoting means notifies the user of the result of the determination made by the determining means, for example. Further, for example, the selection of the broadcast contents whose reception cannot be completed is suppressed based on the result of the judgment by the judgment means. It may have both functions.

Record in the recording means. With this, the broadcast contents can be obtained to the end.

[0019] Preferably, the broadcast receiving apparatus of the present invention includes a recordable determination unit, and the recordable determination unit, even when the scheduled movement end time, which is the elapsed time of the scheduled movement time, is before the broadcast end time, It is determined whether or not a predetermined recordable condition for recording broadcast contents from the end of movement to the end of broadcasting is satisfied. Then, the user may be notified of information indicating that reception of the broadcast content satisfying the recordable condition can be completed . Further, the broadcast content satisfying the recordable condition may be treated as the broadcast content capable of completing reception. According to the present invention, it is possible to include broadcast contents that do not end while moving within an allowable range as reception targets or candidates. More broadcast contents are targeted for reception within a reasonable range, and the broadcast receiving device becomes convenient.

For example, the predetermined recordable condition is satisfied when the time from the scheduled movement end time to the broadcast end time is less than or equal to the predetermined threshold time. In addition, for example, when the expected data amount of the broadcast content from the end of the movement to the end of the broadcast is less than the allowable recording capacity of the broadcast recording means. Further, for example, it is estimated that a predetermined battery charge state is secured after recording the broadcast content from the end of movement to the end of broadcasting.

Preferably, the broadcast contents from the end of movement to the end of broadcast are recorded even when the power-off operation is performed by the user. For example, the moving body is a vehicle, and the power-off operation is an operation of turning off the ignition switch.

Preferably, the receiving apparatus of the present invention includes an alternative broadcast content search means. The alternative broadcast content search means searches for an alternative broadcast content to be broadcast at another time when the reception of the broadcast content selected by the user cannot be completed. Preferably, the alternative broadcast content is presented to the user. The alternative broadcast content is preferably the same as the broadcast content selected by the user. Alternatively, the alternative broadcast content may be broadcast content similar to the broadcast content selected by the user (related broadcast content, for example, broadcast content of the same type or broadcast content of the same genre).

According to the present invention, even when reception of the broadcast content selected by the user cannot be completed, the user's wishes can be satisfied by searching the alternative broadcast content, and the broadcast receiving apparatus becomes convenient.

[0024] Preferably, the alternative broadcast content search means searches for the alternative broadcast content when there is a shift from the reception completion possible to the reception completion impossible due to the change in the scheduled travel time. It is possible to appropriately receive the broadcast content that can be completed in response to the change in the situation.

Preferably, when the reception of the broadcast content selected by the user for the reception reservation cannot be completed, the alternative broadcast content is reserved for reception. In the present invention, the reception reservation includes a reservation (record reservation) for receiving and recording.
It is preferable to replace the reservation target with the alternative broadcast content when the scheduled travel time changes during the standby due to the reception reservation, and it is possible to take appropriate measures to complete the broadcast reception.

Preferably, the end time of the broadcast contents is obtained from the program arrangement information of the digital broadcast as the supplementary information. Further, preferably, the planned travel time is a time estimated based on traffic congestion information obtained from outside the vehicle by communication, for example, VICS information. It is possible to obtain accurate information for determining whether reception can be completed.

As explained above, according to the present invention,

By making good use of this program arrangement information effectively, the characteristic processing of this embodiment is performed.

Returning to FIG. 1, the receiver control section 7 has a planned moving time acquisition section 31, a reception completion availability determination section 33, a determination result notification section 35, and a program recording control section 37 as a configuration related to the present invention. .

The planned travel time acquisition unit 31 acquires the planned travel time of the vehicle from the navigation device 21. In this embodiment, the estimated arrival time at the destination is acquired as the planned travel time. In the navigation device 21, the route search unit 23 searches for an appropriate route to a destination designated by the user using map data by the Dijkstra method or the like. The VICS information acquisition unit 25 uses the VICS (Vehicl
e Information and Comunication System), which obtains road information such as traffic congestion from external information centers by communication. The estimated travel time estimation unit 27 uses VI
By referring to the CS information, the required time along the route to the destination is obtained, and the estimated arrival time is estimated. Vehicle position and VI
The CS information is monitored to constantly correct the estimated arrival time.

The reception completion availability determination unit 33 compares the program end time Te obtained from the program arrangement information with the estimated arrival time Td (that is, the movement end time) obtained from the navigation device 21. Information about the program selected by the user may be processed. Information of multiple programs that are on air or scheduled to air may be processed. Based on the comparison result, if the program end time Te is before the estimated arrival time Td, it is determined that the reception can be completed. Otherwise, it is determined that reception cannot be completed.

The judgment result notifying section 35 notifies the user of the judgment result by the reception completion possibility judging section 33 by appropriately using the speaker 13 and the display 15. Preferably, the determination result is reflected on the screen showing the program arrangement information. At least one of the broadcasting station, the channel, and the program name, or the display portion of other information shows the result of the reception completion determination. Details will be described later.

The program recording control section 37 controls recording of program contents in the program recording device 9. In this embodiment,
In particular, when the reception cannot be completed, the processing for recording the remaining program content portion is performed.

Next, with reference to FIG. 3, characteristic processing by the receiver control unit 7 of the broadcast receiving apparatus 1 will be described. The process of FIG. 3 starts when the user selects a program to receive. In S10, the end time Te of the program selected by the user is obtained from the program arrangement information. When the user selects a broadcasting station or channel, it is considered that the program currently being broadcast by the broadcasting station or channel has been selected.

At S12, the estimated arrival time Td at the destination is acquired from the navigation device 21. And T
If d> Te, it is determined in S14 that the reception can be completed. At this time, the user may be notified on the display 15 that the reception can be completed. Then, in S24, the program content is reproduced on the speaker 13 and the display 15.

On the other hand, if Td> Te in S14, S
In 18, it is determined that the reception cannot be completed. In this case, S2
0 indicates that reception cannot be completed.
Notify the user with. At this time, the user is inquired whether or not to force the reception. When the user instructs the forced reception, YES is determined in S22, and the content is received and reproduced in S24. On the other hand, if the user does not instruct the reception enforcement, the program selected by the user is not received. Then, selection of another program or broadcasting station is prompted.

Next, FIG. 4 shows another example of characteristic processing by the receiver controller 7. In FIG. 3 above, the processing for the program selected by the user is performed. On the other hand, in FIG. 4, processing is performed for all programs that satisfy appropriate conditions. All programs may be all programs that are being broadcast or are scheduled to be broadcast by all broadcast stations or channels, which are obtained from the sequence information. Further, all programs included in a range in which a period, a broadcasting station, or a channel is appropriately limited may be used.

The process of FIG. 4 starts when the user gives an instruction to display information regarding the program list. First, the program end time Te is obtained for each of all the programs to be processed (S30). Next, the estimated arrival time Td at the destination is acquired as in FIG. 3 (S32). The initial value of N is set to 1 (S34).

Then, the program end time Te of the Nth program
(N) is acquired (S36), and Td and Te (N) are compared (S38). If Td> Te (N), the N-th program is added to the reception completion possible programs (S40). Td> T
If it is not e (N), the N-th program is added to the reception impossible programs (S42). It is determined whether or not the determination process for all programs has been completed (S44). If not completed, N = N + 1 is set (S46), and the process returns to S36. In this way, all programs can be judged whether reception can be completed,
The programs that can be received completely and those that cannot be received are sorted and distributed.

When the determination of all programs is completed in S44, S4
8, the program list information is presented on the display 15. At this time, display based on the above determination result is performed.

Preferably, the user is presented with information about the program (broadcast content) that can be received, and the user is suppressed from being presented with information about the program (broadcast content) that cannot be received. In short, only the programs registered as the reception completion possible programs in S40 are displayed as a list. The program selected by the user from the program list is received and reproduced using the display 15 and the speaker 13.

Alternatively, in another preferable display form, information about a program (broadcast content) that can be received and a program (broadcast content) that cannot be received may be presented to the user in different forms. For example, color-coded display is performed. In short, the program registered as the reception completion possible program in S40 and the S
The program registered as the program whose reception cannot be completed in 42 is displayed in a different color. Besides the color coding, the brightness may be different. It suffices to display an arbitrary display that allows the user to determine whether or not the reception is completed. Particularly preferably, the programs for which reception can be completed are displayed more emphasized than the programs for which reception cannot be completed.

The above is the processing of FIG. The program list was displayed here. As a modification, a list of broadcasting stations or channels may be displayed. At this time, whether or not to display is determined depending on whether or not reception of the program being broadcast by each broadcasting station or channel can be completed. Alternatively, the display form is changed.

Further, the processing of FIG. 4 can be applied to other than the list display. For example, when sequentially displaying the related information of a plurality of programs (or broadcasting stations and channels), the related information of the programs for which reception cannot be completed is not displayed and skipped. Alternatively, the display color of the related information is changed depending on whether the reception can be completed.

The present embodiment has been described above. According to this embodiment, it is determined whether the reception of the broadcast can be completed based on the program end time obtained from the program arrangement information and the planned travel time obtained by the navigation technique. Then, the user is notified of information about the determination result. Therefore, the user receives the content whose reception can be completed, and completes the reception of the content before the movement ends. It is possible to prevent selection of content that cannot be completely received.
Then, the complete reproduction of the program selected in the vehicle can be guaranteed, and the user can select the content with confidence.

As an advantage of the present embodiment, since the above notification is performed, the user does not have to match the movement schedule and the program schedule by himself / herself, and the program that can be completed in reception can be selected easily, easily and at ease. The points are raised. In particular, considering that the above-mentioned matching work is very complicated for the user of the mobile body, the notification of the present embodiment is useful, and the convenience of the broadcast receiving apparatus is improved.

According to this embodiment, it is possible to avoid a situation in which the movement ends in the middle of the program.
As a result, the user can enjoy the program to the end,
Or you can avoid missing the necessary information. Furthermore, it is possible to avoid a situation in which the user is restrained on the spot even though he / she has finished moving because he / she wants to receive the program to the end.

Particularly in digital broadcasting, it is possible to download data in a program or the like. The data to be downloaded is, for example, music data, and is, for example, some program. It is also possible to charge and download music data and the like. In such a case, for example, when it is expected that the download cannot be completed, the program with the download is not displayed. In this way, the present embodiment makes it possible to determine whether or not the download is completed.
Be beneficial.

Further, in this embodiment, some notification forms are exemplified. In the process of FIG. 3, the user is notified that the reception of the program selected by the user cannot be completed. In this case, the user can easily know the reception completion availability status of the desired program.

In the process of FIG. 4, as the first notification form, the information about the programs that can be received is presented to the user and the information about the programs that cannot be received is suppressed from being presented to the user. Is proposing that. In this mode, since only the programs that can be received are presented,
The user can easily select a program whose reception can be completed. It is possible to effectively prevent selection of programs for which reception cannot be completed.

In the processing of FIG. 4, as another notification form, when information about a plurality of programs is presented to the user, the programs that can be received and the programs that cannot be received are displayed to the user in different forms. Presenting. The user can easily understand whether or not reception of each program can be completed. Such a program may be selected by knowing that reception cannot be completed.

More preferably, when the presentation form is divided according to whether or not reception can be completed, the programs that can be received are highlighted more than the programs that cannot be received. Use prominent colors and brightness. The user can more easily select a program whose reception can be completed.

The "presentation of information about a program" described here includes presentation of a corresponding broadcasting station or a corresponding channel. In addition to the above-mentioned display, a speaker or an indicator (not shown) may be used for presentation and notification.

Further, in the present embodiment, whether or not the reception can be completed is determined based on the estimated arrival time obtained by using the VICS information obtained by the navigation function. By properly combining VICS information and program arrangement information, accurate judgment can be realized.

[Selection Suppression Processing] In the above embodiment, the judgment result notifying section 35 functions as a notification means for notifying the user of the judgment result of whether reception completion is possible or not. This notification means
It is one form of the reception completion promoting means of the present invention for promoting the reception of the broadcast content that can be received. However, the reception completion promoting means is not limited to the notifying means. Other configurations may be applied that facilitate the reception of broadcast content that is ready to be received. For example, a selection processing unit that suppresses selection of broadcast contents that cannot be completely received may be provided. It is possible to prevent the user from accepting the selection of the broadcast content that cannot be completely received. As a result, it is possible to effectively prevent the selection of broadcast contents for which reception cannot be completed.

[Reservation Process] In the above embodiment, the process mainly when the user selects a program to be received in real time has been described. However, similar processing is performed when a program is selected for reservation of reception. The reception reservation includes a reservation (record reservation) for receiving and recording. Further, this point is the same in the following embodiments.

[Recording Process] In the above embodiment, whether or not the reception can be completed is determined based on the expected result of the traveling time of the vehicle. However, it is possible that the actual movement end time is before the scheduled movement time has elapsed. In this case, reception may not be completed as a result.

In view of this situation, the receiving apparatus of this embodiment is
When the broadcast reception is not completed because the actual movement end time is before the scheduled movement time has elapsed, the broadcast content from the movement end time to the broadcast end time is recorded in the program recording device 9. This process is performed by the program recording control unit 37 of the receiver control unit 7.
Done by

FIG. 5 shows a specific example of the above recording process. From the navigation device 21, the estimated arrival time T
d is available. Since Td is after the program end time Te, it is determined that the target program can be received. However, it is assumed that the vehicle arrives at the destination at time TdR early for some reason. Some reason is, for example, the elimination of unexpected traffic congestion.

In this case, the program recording control unit 37 causes the program recording device 9 to record the program content from the actual arrival time TdR to the program end time Te. This recording is performed regardless of whether or not the ignition switch of the vehicle is turned off by the user. For this recording, even if the ignition switch is turned off, power can be supplied from a battery (not shown) under the control of the receiver controller 7.
A power-related circuit is configured.

As described above, in the present embodiment, even when the movement ends unexpectedly early, the program content from the movement end to the broadcast end can be obtained. It is possible to avoid such a situation that the user has to stay in the vehicle even though the user arrives at the destination early. The user may play the rest of the recorded program content during the next move, for example.

[Correction of Receiving Completion Judgment] In addition, the planned travel time estimation unit 27 of the navigation device 21 always
The estimated arrival time Td is monitored. Changes in road conditions,
The estimated arrival time Td constantly changes according to the progress of the movement of the vehicle. When the estimated arrival time Td changes, it is preferable to send the new time Td to the planned travel time acquisition unit 31. As a result, the receiver control unit 7 makes a real-time determination as to whether or not reception of the program currently being received can be completed, presents the result to the user, and promotes reception of other programs that can be received. Then, the recording process due to the unexpected result can be avoided as much as possible.

<Embodiment 2>> Next, a preferred second embodiment of the present invention will be described.

FIG. 6 shows the broadcast receiving apparatus 41 of this embodiment. A recordable determination unit 43 and a charge state acquisition unit 45 of the receiver control unit 7 are added to the device of FIG.

The recordability judging section 43 functions when the reception completion possibility judging section 33 judges that the reception of the program cannot be completed. The recordable determination unit 43 determines whether or not a predetermined recordable condition for recording the program portion from the movement end to the broadcast end is satisfied even when the estimated movement end time is before the broadcast end time. .

Referring to FIG. 7, it is assumed that the estimated arrival time Td (movement end time) of a certain program is after the program end time Te. In this case, it is determined that the reception cannot be completed, as described above. The recordable determination unit 43 is T
It is determined whether or not a recordable condition for recording the program content from d to Te (hereinafter, the remaining content) is satisfied.

The recordable condition is a condition under which it can be determined that there is no problem even if the remaining content is recorded. In this embodiment, three recordable conditions are disclosed as an example.

(1) The time from the end of movement to the end of broadcasting must be less than or equal to a predetermined threshold time. The threshold time is set appropriately. For example, a few minutes to a sufficient level. It is set in consideration of the capacity of the recording device and the battery capacity.

(2) The expected data amount of the remaining content is within the allowable recording capacity of the program recording device 9. This is to avoid over recording capacity. It is preferable to make the determination based on the recording status at the time of the determination.

(3) It is presumed that a predetermined battery charge state is secured after recording broadcast contents from the end of movement to the end of broadcasting. Consider the state of charge at the end of movement expected from the state of charge at the time of determination. For example, it may be determined that the recordable condition is satisfied when the current charge state is equal to or higher than a predetermined value. In detail, various parameters may be considered. Consider the planned travel time. It is considered that a sufficient amount of charge is recovered and secured if the current amount of charge is at least the traveling time is long.

The current charging state is obtained from the outside by the charging state acquisition unit 45. Preferably, the ECU having a battery management function sends charge state information detected by using parameters such as a voltage value, a current value, and a temperature as needed. The charge state acquisition unit 45 may directly process the signal from the sensor.

The recordable determination section 43 is configured to perform the above (1) to
It may be configured to determine only one of (3).
Also, it may be configured to determine a plurality of conditions.
In the latter case, if it is determined that recording is possible when a plurality of conditions are satisfied at the same time, a more reliable determination can be made.

FIG. 8 shows the characteristic processing of this embodiment including the above-mentioned recordable determination. The process of FIG. 8 is the same as that of FIG.
This is a modification of the process of. The common steps will be denoted by the same reference numerals, and description thereof will be omitted as appropriate.

3 to 8 are common to S10 to S14. The end time Te of the selected program is obtained from the program arrangement information in S10, and the estimated arrival time Td is acquired in S12. If Td> Te, it is determined in S14 that the reception can be completed. If the reception can be completed, the selected program is received and reproduced in S24.

On the other hand, if Td> Te in S14, S
In 18, it is determined that the reception cannot be completed. Here, the recordable determination processing characteristic of the present embodiment is performed. That is,
In S50, as described above, the recordability determination unit 43
It is determined whether or not the recordable condition is satisfied for the remaining contents from the end of movement to the end of broadcasting.

If S50 is NO, the process proceeds to S20, and the determination result notifying section 35 notifies the user that the reception cannot be completed. The user is inquired as to whether or not to enforce the reception (S22). If the forced instruction is given, the process proceeds to S24 and the target program is received.

If S50 is YES, the user is informed in some display form that the reception of the program can be completed under the condition of partial recording (S52). This processing is performed by the determination result notifying unit 35. Further, the user is inquired whether or not to receive the target program (S54). If the user indicates reception, the process proceeds to S24 to receive and reproduce the target program. If the user does not instruct the reception, the process is terminated and the selection of another program is prompted.

Next, FIG. 9 shows another example of the preferred processing of this embodiment. The determination of the satisfaction of the recordable condition in S50 is the same in FIGS. 8 and 9. In the subsequent processing, S52 and S54 of FIG. 8 are eliminated. When it is determined in S50 that the recordable condition is satisfied, the target program is considered to be the reception completion program (S60). After that, the target program is treated as a program whose reception can be completed. That is, the process proceeds to S24 and S1
The program is received and reproduced in the same manner as the reception completion possible program determined to be YES in 4.

As a modification of FIG. 9, it may be possible to determine in S14 whether or not the program satisfies the recordable condition. For example, it is determined that the programs can be received, except for programs that end after a threshold time or more from the estimated arrival time Td (Td + threshold time Ta> Te is determined).

The present embodiment has been described above. As described above, according to the present embodiment, it is possible to include a program that does not end while moving within an allowable range as a reception target or a candidate. More broadcast contents are targeted for reception within a reasonable range, and the broadcast receiving device becomes convenient.

For the user, even if the end of reception is a little later than the end of movement, the user can select a program that he or she likes. Actually, even if the reception cannot be completed during the movement, the recorded remaining content may be reproduced later, so that the harmful effect is small. When the traveling time is prolonged, the reception of the entire program can be completed.

In this embodiment, two processes (FIGS. 8 and 9) when the recordable condition is satisfied are disclosed. In the process of FIG. 8, the user is notified that the reception can be completed under the condition of partial recording. As a result, the user can start receiving after knowing that it is impossible to complete the reception from the beginning and a part depends on the recording function. You can select programs with confidence.

In the process of FIG. 9, the program satisfying the recordable condition is treated in the same manner as the program whose reception can be completed. The user is not notified that partial recording is required. In this case, the desired result may not be obtained for the user who absolutely wants to avoid relying on the recording. However, if we originally envisioned a program that would only stick out a little from the end of the move, there would be no major problems. Rather, there is an advantage that it is possible to prevent the user from wondering whether or not to receive the signal.

In this embodiment, the process relating to the recordable condition is applied to the process of determining whether or not the reception completion of the selected program is possible. However, the present embodiment can be similarly applied to the processing (see FIG. 5) of determining whether or not reception is completed for a plurality of programs. For example, a program for which a recordable condition is satisfied is displayed in the program list display.

Further, as described above, the processing of this embodiment is similarly applied when the user makes a reception reservation operation.

As a result of reception according to the present embodiment, when the movement ends before the end of broadcasting, the actual remaining contents are recorded in the program recording device 9 under the control of the program recording control unit 37. At this time, the recording process is performed regardless of whether the ignition switch is off.

In addition, in the above-described first embodiment, the process of recording the remaining contents when the actual arrival of the destination is unexpectedly early has been described. Also in this case, the recordable condition may be determined upon arrival and recording may be performed only when the condition is satisfied.

<Third Embodiment>> Next, a preferred third embodiment of the present invention will be described.

FIG. 10 shows a broadcast receiving apparatus 51 of this embodiment.
Is shown. An alternative program search unit 53 and a reservation processing unit 55 of the receiver control unit 7 are added to the device of FIG.

The alternative program search unit 53 functions when the reception completion availability determination unit 33 determines that the reception of the program cannot be completed, and searches for an alternative program (alternative broadcast content). The alternative program is a program that is broadcast at a different time (some duplication is allowed) from the original program. The alternative program is preferably identical in content to the original program. Alternatively, the alternative program may be a program similar to the original program, that is, a program related to the program selected by the user, for example, a program of the same type or a program of the same genre.

The search for the alternative program is performed using the program arrangement information. As described above, the program arrangement information includes the information corresponding to the program section of the newspaper. Therefore, a program having the same content or similar content can be obtained from the program arrangement information. The reservation processing unit 55 performs reception reservation processing using the search result of the alternative program. The reception reservation includes a reservation (record reservation) for receiving and recording.

FIG. 11 shows the processing of this embodiment including the alternative program search. Here, the present embodiment is applied to a process in which a user selects a program and reserves reception.

When the user selects the reserved program (S7
0), the end time Te of the selected program is acquired (S7
2) Further, the estimated arrival time Td to the destination is acquired (S74). Then, it is determined whether Td> Te, that is, whether reception can be completed (S76). S72 to S76 are the same as S10 to S14 in FIG.

If Td> Te, the reception can be completed, so the reservation process is performed (S77) and the reception standby state is entered (S78). This processing is performed by the reservation processing unit 55.

On the other hand, if Td> Te is not satisfied, that is, if reception cannot be completed, the process proceeds to S80 to search for an alternative program. If there is an alternative program in S81, the end time T of the alternative program
e1 is acquired (S82), and it is determined whether Td> Te1 (S84). If Td> Te1, it is possible to complete the reception of the alternative program. Therefore, the user is inquired whether or not to reserve the alternative program (S86). As a result of the inquiry, if it is determined in S88 that the reservation should be made, S
Proceeding to 77, reservation processing is performed, and in S78, the reception standby state is entered.

If there are a plurality of alternative programs,
For each alternative program, it is determined whether or not the reception is completed. When a plurality of alternative programs can be received, one of them may be selected according to an appropriate priority criterion. Alternatively, multiple alternative programs may be presented to the user. The user can select the desired alternative program.

On the other hand, if there is no alternative program in S81, or if the reception of the alternative program cannot be completed in S84, then again in S8.
When the reservation is not instructed in 8, the process proceeds to S90 and notifies that the reception of the selected program cannot be completed.

After the reservation waiting state is set in S78, it is monitored whether the estimated arrival time Td has changed (S92). When the estimated arrival time Td changes, the navigation device 21 sends a new estimated arrival time Td to the receiver controller 7. At this time, S78 becomes YES and S78
Return to 76. Therefore, the reception completion availability determination is performed based on the new estimated arrival time Td after correction. When the determination result changes from the reception completion possible to the reception completion impossible, the alternative program is searched. If the reception completion possibility determination is maintained, the reception standby state is continued.

The present embodiment has been described above. According to the present embodiment, even when reception of the program selected by the user cannot be completed, by searching for the alternative program, the user's wishes can be satisfied and the broadcast receiving apparatus becomes convenient.

Further, in the present embodiment, as shown in S92 in FIG. 11, when the scheduled movement time changes, it is detected that there is a transition from the reception completion possible to the reception completion impossible, and the alternative program is changed. To be searched. It is possible to complete the reception of the desired broadcast content in response to changes in the situation.

Further, in the present embodiment, when the reception of the program selected for reception reservation cannot be completed, the substitute program is reserved for reception. In particular, when the scheduled travel time changes during the standby due to the reception reservation, the reservation target is replaced with the alternative program, and appropriate measures for completing the broadcast reception can be taken.

Also, as described above, the alternative program may be limited to the same program as the original program. Alternatively, another similar program having a genre-related relationship with the original program may be searched as an alternative program. The latter process has the advantage that more programs can be presented to the user.

Further, in FIG. 11, the reservation process is performed. However, the present embodiment can be applied to a process of selecting a program to be received in real time. That is, when the reception of the selected program cannot be completed, the alternative program may be presented.

Various embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiment, and those skilled in the art can arbitrarily modify the present embodiment within the scope of the present invention.

For example, in this embodiment, the present invention is MPE.
Although applied to a G2 compliant receiver, the invention is not so limited. The present invention may be applied to analog broadcasting as well as other types of digital broadcasting as long as it is possible to receive appropriate incidental information indicating the end time of the content.

Further, in the present embodiment, one program of television broadcasting is assumed as one unit of content (broadcast content).
On the other hand, a part of the program may be one content.
The unit of content may be a set of a plurality of programs.

It goes without saying that the content is not limited to television broadcasting. The present invention can be similarly applied to broadcasting of other genres. The present invention can be similarly applied to radio broadcasting and music broadcasting. Also in this case, the content unit may be a program, a part thereof, or a set of a plurality of programs. Further, the content may be a program (download program) transmitted to a broadcast receiving device as a terminal by broadcasting. In short, any chunk of data within the broadcast itself is content.

In addition, the present invention may be implemented in a method aspect and a recording medium aspect in addition to the apparatus aspect. In the aspect of the recording medium, a program that causes a computer to perform the processing of the present invention is recorded in the recording medium. A program for realizing the processing of the present invention may be incorporated in the program for processing the digital broadcast signal in the form of a module or the like.
