If there is a recording medium having the remaining recordable time (in the case of YES), the recording medium is selected and the program is recorded (step S17). In step S14, if there is no recording medium having the same remaining recordable time as the program that the user intends to record (NO), the controller 16 records the recording time of the program that the user intends to record. If there is a recording medium whose remaining recordable time is longer than that of the recording medium and the time difference is the smallest (step S15), if there is a corresponding recording medium (in the case of YES), the process proceeds to step S17. Then, the recording medium is selected to record the program. If there is no corresponding recording medium in step S15 (NO), the recording medium having the longest remaining recordable time is selected to record the program (steps S16 and S17).

  Next, the controller 16 determines whether or not the remaining recordable time of the recording medium has become zero when the program is recorded on the selected recording medium (step S18). When the remaining recordable time of the recording medium becomes zero (in the case of YES), a command is transmitted from the recording medium to notify that the remaining recordable time has become zero, and the controller 16 that has received the command again returns to the home The remaining recording time is inquired to a plurality of recording media existing therein (step 19), and the process returns to step S14 to repeat the process. In step S18, if the remaining recordable time of the selected recording medium does not become zero (in the case of NO), the program is continuously recorded and the process is terminated.

  According to these embodiments, a controller that receives a program recording command from a user while receiving stream information of a plurality of programs at the same time using a plurality of tuners existing in the home is provided with a plurality of tuners. And the address of the recording medium, the recording time of the program to be recorded, the remaining recordable time of the recording medium, and the combination that can record the program most efficiently among the combinations of multiple tuners and recording media You can select and record a program.

  As a procedure for recording a program, a recording reservation for a program with a new broadcast time zone may be made, and then a recording reservation for a program with an old broadcast time zone may be made. For example, in the case of making a recording reservation for a program broadcast on October 2nd on October 2nd, and making a recording reservation for a program broadcasted on October 10th on October 3rd of the next day, etc. is there. In order to record programs most efficiently by combining multiple tuners and recording media that exist in the home, it is necessary to consider the time zone during which the program is actually broadcast, and after adjusting the order, It is necessary to select a recording medium.

S25). Further, the controller 16 compares the remaining recordable time of the recording medium, selects the recording medium having the longest remaining recordable time (step S26), and records the program reserved for recording by the user (step S27). At this time, if there are a plurality of recording media having the same remaining recordable time, the recording medium to be selected is determined by referring to the address assigned to the device.

  Next, the controller 16 determines whether or not the remaining recordable time of the recording medium has become zero when the program is recorded on the selected recording medium (step S28). When the remaining recordable time of the recording medium becomes zero (in the case of YES), a command is transmitted from the recording medium to notify that the remaining recordable time has become zero, and the controller 16 that has received the command again returns to the home The remaining recordable time is inquired to a plurality of recording media existing therein (step 29), the process returns to step S26, the recording medium having the longest remaining recordable time at that time is selected again, and the program recording is continued. In step S28, if the remaining recordable time of the selected recording medium does not become zero (in the case of NO), the program recording is continued as it is, and the process ends.

  FIG. 9 is a flowchart for explaining another example of the recording control process of the digital broadcast receiving system according to the third embodiment. Similarly to the processing flow shown in FIG. 8, first, the controller 16 accepts a recording reservation from the user (step S31), and the recording start time information of the program that the user intends to record and has been registered by the user in the past. The start time information of recording reservations that have not been executed is compared (step S32). When the recording start time of the program to be recorded is older than the recording reservation start time registered in the past (in the case of NO), the controller 16 sets the recording reservation according to the start time at which the program is actually broadcast. Are rearranged (step S33). In step S32, when the recording start time of the program to be recorded is newer than the recording reservation start time registered in the past (in the case of YES), the process proceeds to step S34.

  Next, the controller 16 acquires the recording time of the program that the user is going to record (step S34), and further acquires the remaining recordable time at the present time from a plurality of recording media existing in the home (step S34). S35). Further, the controller 16 compares the recording time of the program to be recorded by the user with the remaining recordable time of the acquired plurality of recording media (step S36), and is the same as the recording time of the program to be recorded. If there is a recording medium having the remaining recordable time (in the case of YES), the recording medium is selected and the program is recorded (step S39). In step S36, when there is no recording medium having the same recordable time as the program to be recorded (in the case of NO), the remaining recordable time is larger than the recording time of the program to be recorded and It is determined whether or not there is a recording medium having the smallest time difference (step S37). If the corresponding recording medium exists (in the case of YES), the process proceeds to step S39 to select the recording medium and select the program. Record. In step S37, if there is no corresponding recording medium (NO), the recording medium having the longest remaining recordable time is selected to record the program (steps S38 and S39).

  Next, the controller 16 determines whether or not the remaining recordable time of the recording medium has become zero when the program is recorded on the selected recording medium (step S40). When the remaining recordable time of the recording medium becomes zero (in the case of YES), a command is transmitted from the recording medium to notify that the remaining recordable time has become zero, and the controller 16 that has received the command again returns to the home The remaining recording time is inquired to a plurality of recording media existing therein (step 41), and the process returns to step S36 to repeat the process. In step S40, if the remaining recordable time of the selected recording medium does not become zero (in the case of NO), the program is continuously recorded and the process is terminated.

  According to this embodiment, a controller that has received a recording reservation from a user when simultaneously receiving stream information of a program using a plurality of tuners existing in the home can record recordings registered by the user in the past. By comparing the reservation information with the recording reservation information to be registered at present, the optimum tuner / recording medium combination is selected and the program is recorded in accordance with the time zone when the program is actually broadcast. Can do.

  Furthermore, as a procedure for recording a program using a plurality of tuners, there is a case where a time period for recording a program is covered, or recording of another program is started while a certain program is being recorded. For example, while recording a 4-hour program using a tuner at 7 o'clock, a 2-hour program is recorded using another tuner at 8 o'clock, and another tuner is used at 10 o'clock. For example, when a one-hour program is recorded. In order to record a program most efficiently by combining multiple tuners and recording media that exist in the home, it is determined whether the selected recording medium is currently in use, and the recording medium is used. In such a case, it is necessary to control the recording method so that programs of a plurality of tuners can be recorded on one recording medium at the same time, thereby recording the program.

(Fourth embodiment)
A fourth embodiment of the present invention will be described with reference to FIG. A controller 16 that receives a program recording command from a user when receiving stream information of a plurality of programs simultaneously using a plurality of tuners (tuners 11, 21, 31) present in the home is The recording time of the program to be recorded is acquired, and a command for inquiring the remaining recordable time at the present time is transmitted to a plurality of recording media (HDDs 12, 22, and 32). The recording medium that has received the command confirms the remaining recordable time at the present time, returns it to the controller 16, and if recording is currently being performed, , Send a command that it is in use at the same time.

  When a combination of a plurality of tuners and recording media existing in the home is selected to select a combination that can record a program most efficiently, if the recording medium to be selected is already in use, the controller 16 The recording method of the recording medium can be changed so that stream information of a plurality of tuners can be recorded on one recording medium at the same time. A method for selecting an optimum combination among the combinations of the tuner and the recording medium can be performed by the methods shown in the first embodiment and the second embodiment.

  FIG. 10 is a flowchart for explaining an example of the recording control process of the digital broadcast receiving system according to the fourth embodiment. First, the controller 16 receives a program recording command from the user (step S51), and acquires the recording time of the program that the user intends to record (step S52). Further, the controller 16 transmits a command for inquiring the remaining recordable time to a plurality of recording media existing in the home. The recording medium that has received the command confirms the remaining recordable time at the present time and whether or not recording is currently being performed, and returns the command as a command. The remaining recordable time and the usage state at the present time are acquired (step S53).

  Next, the controller 16 compares the remaining recordable times of the acquired plurality of recording media, selects the recording medium with the longest remaining recordable time (step S54), and the selected recording medium is recording. It is determined whether or not the recording is in progress (step S55). If recording is in progress (YES), the recording method is changed so that the recorded program and the program to be recorded can be recorded simultaneously on the selected recording medium. The program is recorded (step S56). If the selected recording medium is not recording in step S55 (NO), the program is recorded as usual (step S57).

  Next, the controller 16 determines whether or not the remaining recordable time of the recording medium has become zero when the program is recorded on the selected recording medium (step S58). When the remaining recordable time of the recording medium becomes zero (in the case of YES), a command is transmitted from the recording medium to notify that the remaining recordable time has become zero, and the controller 16 that has received the command again returns to the home The remaining recordable time is inquired to a plurality of existing recording media (step 59), the process returns to step S54, the recording medium having the longest remaining recordable time at that time is selected again, and the recording of the program is continued. In step S58, if the remaining recordable time of the selected recording medium does not become zero (in the case of NO), the program recording is continued as it is, and the process ends.

  FIG. 11 is a flowchart for explaining another example of the recording control process of the digital broadcast receiving system according to the fourth embodiment. First, the controller 16 receives a program recording command from the user (step S61), and acquires the recording time of the program that the user intends to record (step S62). Further, the controller 16 transmits a command for inquiring the remaining recordable time to a plurality of recording media existing in the home. The recording medium that has received the command confirms the remaining recordable time at the present time and whether or not recording is currently being performed, and returns the command as a command. The remaining recordable time and usage status at the present time are acquired (step S63).

  Next, the controller 16 compares the recording time of the program to be recorded with the remaining recordable time of the acquired plurality of recording media (step S64), and the remaining recording time equal to the recording time of the program to be recorded. If there is a recording medium having a possible time (in the case of YES), the recording medium is selected and the process proceeds to step S67. In step S64, if there is no recording medium having the same recordable time as the program that the user intends to record (in the case of NO), the remaining recording medium is longer than the recording time of the program to be recorded. It is determined whether or not there is a recording medium with a long recordable time and the time difference is minimum (step S65). If there is a corresponding recording medium (in the case of YES), the recording medium is selected and the process proceeds to step S67. To do. If there is no corresponding recording medium in step S65 (NO), the recording medium having the longest remaining recordable time is selected (step S66).

  Further, the controller 16 determines whether or not the selected recording medium is being recorded (step S67). If recording is in progress (in the case of YES), the controller 16 intends to record the recorded program. The program is recorded by changing the recording method so that the program can be recorded simultaneously on the selected recording medium (step S68). If the selected recording medium is not recording in step S67 (NO), the program is recorded as usual (step S69).

  Next, the controller 16 determines whether or not the remaining recordable time of the recording medium has become zero when the program is recorded on the selected recording medium (step S70). When the remaining recordable time of the recording medium becomes zero (in the case of YES), a command is transmitted from the recording medium to notify that the remaining recordable time has become zero, and the controller 16 that has received the command again returns to the home The remaining recording time is inquired to a plurality of recording media existing therein (step 71), and the process returns to step S64 to repeat the process. In step S70, if the remaining recordable time of the selected recording medium does not become zero (in the case of NO), the program is continuously recorded and the process is terminated.

  According to the present embodiment, when a plurality of tuners existing in the home are used to simultaneously receive program stream information, a controller that receives a program recording command from a user can receive a plurality of controllers existing in the home. When recording a program with the most efficient tuner and recording medium, it is determined whether the selected recording medium is currently being recorded, and if recording is in progress, The recording method can be changed so that programs of a plurality of tuners can be recorded simultaneously on the selected recording medium, and the program can be recorded. The technique for recording a program of a plurality of tuners on one recording medium at the same time is a known technique, and thus detailed description thereof is omitted here.

  By the way, as in the above embodiment, when a program is recorded by combining a plurality of tuners and recording media existing in the home, and the remaining recordable time of the recording medium becomes zero, a plurality of recordings are performed again. If the remaining recordable time of the medium is re-acquired, and the recording medium that can be recorded most efficiently at that time is selected again and recording of the program is continued, The controller needs to recognize from which time on the recording medium the continuation of the program has been recorded. For example, when recording on the recording medium at address 001, the remaining recordable time becomes 0, and when the recording medium is selected again and recording of the program is continued on the recording medium at address 003. The controller recognizes that the continuation of the program will be reproduced from the position 30 minutes from the start of the recording medium at address 003 after the reproduction of the recording medium at address 001, smoothly switches the recording medium, and reproduces the program. It becomes necessary to do.

(Fifth embodiment)
A fifth embodiment of the present invention will be described with reference to FIG. When receiving the stream information of a plurality of programs simultaneously using a plurality of tuners existing in the home, the controller that receives the program recording command from the user records the recording time of the program that the user wants to record, The remaining recordable time of the plurality of recording media is acquired, and the combination of the tuner and the recording medium that can record most efficiently is selected from the combinations of the plurality of tuners and recording media, and the program is recorded.

  At this time, if the remaining recordable time of the recording medium becomes 0 when a program is recorded on the selected recording medium, the recording medium notifies the controller that the remaining recordable time has become 0. The command is transmitted, and the controller again acquires the remaining possible time of the plurality of recording media, and selects the tuner and the recording media. At that time, the controller displays the address of the newly selected recording medium and information indicating how many minutes after the start of the newly selected recording medium the program recording is continued, and the remaining recordable time is 0. It can be transmitted as a command to the recording medium.

  The recording medium whose remaining recordable time is 0 receives the command and stores the contents in the storage area, so that when the playback of the recording medium ends, the continuation of the program has which address. Information indicating how many minutes after the start of the recording medium is continued can be transmitted to the controller. When the controller receives / holds this command, it can smoothly reproduce the program by selecting the recording medium having the corresponding address from the recording media in the home and switching the recording media.

  FIG. 12 is a diagram illustrating an example of a format of data transmitted and received between a controller, a tuner, and a recording medium connected via a home network. As shown in FIG. 12A, data used for recording a program on a recording medium includes an address, a recording time of a program that the user wants to record, a remaining recording time of the recording medium, and a remaining recording time of the recording medium. Data indicating that the recording medium has become 0, data indicating the current usage state of the recording medium, and the like. In the figure, the unused portion on the data format is described as NULL.

  In FIG. 12A, an address is a unique address assigned to each device connected to the home network. For example, a controller (address: 1.233.251.00,...), A tuner (address: 1.233.251.02,...), A recording medium (address: 1.233.251.05, 1.233.251.07,...). The recording time of the program that the user wants to record is inquired about the recording time of the program from the controller to the tuner (Ask), and the tuner informs the controller of the recording time of the program that the user wants to record (Answer 2 hours). For the remaining recordable time, the controller inquires of the recording medium about the remaining remaining recordable time (Ask), and the recording medium informs the controller about the remaining remaining recordable time (Answer 4 hours). ) And the like. In addition, information indicating that the remaining recordable time of the recording medium has become zero and information indicating the current usage state are transmitted from the recording medium to the controller when the recording medium is in that state. Information. Hereinafter, an example of each piece of information illustrated in FIG.

(A tuner 31) and a digital broadcast receiving apparatus 3 having an HDD 32 are installed. Here, for example, recording a program
10/1, tuner 11 (address 001): 10/5 broadcast program for 4 hours, 10/2, tuner 21 (address 002): 10/15 broadcast program for 1 hour, 10/3, Tuner 31 (address 003): A 10/10 broadcast program is performed for 3 hours, and the remaining recordable time of each HDD at that time is HDD 12 (address 004): 6 hours, HDD 22 (address 005): 3 Time, HDD 32 (address 006): 2 hours.

  In the first embodiment and the third embodiment described above, 10/1: 10/5 program reservation is performed by selecting the HDD 12 having the longest remaining recordable time. At this time, the remaining recordable time of each HDD is HDD 12 (address 004): 2 (6 hours-4 hours), HDD 22 (address 005): 3 hours, and HDD 32 (address 006): 2 hours.

  Next, 10/2: 10/15 program reservation is performed by selecting the HDD 22 having the longest remaining recordable time. At this time, the remaining recordable time of each HDD is HDD 12 (address 004): 2 hours, HDD 22 (address 005): 2 (3 hours-1 hour), and HDD 32 (address 006): 2 hours.

  Here, since the 10/3: 10/10 program reservation has been made, the 10/2 reservation is canceled once. Therefore, the remaining recordable time of each HDD returns to HDD 12 (address 004): 2 hours, HDD 22 (address 005): 3 hours, and HDD 32 (address 006): 2 hours.

  Next, the order is rearranged, and the 10/3: 10/10 program reservation is performed by selecting the HDD 22 having the longest remaining recordable time. At this time, the remaining recordable time of each HDD is HDD 12 (address 004): 2 hours, HDD 22 (address 005): 0 (3 hours-3 hours), and HDD 32 (address 006): 2 hours.

  Then, the program reservation of 10/2: 10/15 is performed again by selecting the HDD 12 having the longest remaining recordable time and the smallest address. At this time, the remaining recordable time of each HDD is HDD12 (address 004): 1 (2 hours-1 hour), HDD22 (address 005): 0 hour, HDD32 (address 006): 2 hours.

  Similarly, in the above-described second embodiment and third embodiment, the program reservation of 10/1: 10/5 is set so that the remaining recordable time is the same as the recording time or larger than the desired recording time. This is performed by selecting the HDD 12 having the smallest time difference. At this time, if there is no HDD whose remaining recording time is longer than the desired recording time, the HDD having the longest remaining recording time is selected. At this time, the remaining recordable time of each HDD is HDD 12 (address 004): 2 (6 hours-4 hours), HDD 22 (address 005): 3 hours, and HDD 32 (address 006): 2 hours.

  Next, 10/2: 10/15 program reservation is performed by selecting the HDD 12 having the same condition and a small address. At this time, the remaining recordable time of each HDD is HDD 12 (address 004): 1 (2 hours-1 hour), HDD 22 (address 005): 3 hours, and HDD 32 (address 006): 2 hours.

  Here, since the 10/3: 10/10 program reservation has been made, the 10/2 reservation is canceled once. Therefore, the remaining recordable time of each HDD returns to HDD 12 (address 004): 2 hours, HDD 22 (address 005): 3 hours, and HDD 32 (address 006): 2 hours.

  Next, the order is rearranged, and the 10/3: 10/10 program reservation is performed by selecting the HDD 22 from the same conditions. At this time, the remaining recordable time of each HDD is HDD 12 (address 004): 2 hours, HDD 22 (address 005): 0 (3 hours-3 hours), and HDD 32 (address 006): 2 hours.

  Then, the program reservation of 10/2: 10/15 is performed again by selecting the HDD 12 having the same condition and a small address. At this time, the remaining recordable time of each HDD is HDD12 (address 004): 1 (2 hours-1 hour), HDD22 (address 005): 0 hour, HDD32 (address 006): 2 hours.

  Similarly, in the above-described fourth embodiment, it is assumed that the reserved recording time zone is covered, and the recording reservation is performed while the program is being recorded. Here, in the other embodiments, An example of notifying the tuner when the remaining recordable time of the HDD becomes 0 will be described with reference to FIG.

In FIG. 5, the recording reservation of a program is, for example,
The tuner 11 (address 001): 4 hours, 8 o'clock, the tuner 21 (address 002): 2 hours, 10 o'clock, the tuner 31 (address 003): 1 hour. That is, from 7 o'clock, while the tuner 11 is recording a 4-hour program, the tuner 21 makes a recording reservation for 2 hours. Further, while the tuners 11 and 21 are recording a program, the tuner 31 makes a recording reservation for one hour. The remaining recordable time of each HDD at that time is HDD 12 (address 004): 5 hours, HDD 22 (address 005): 2 hours, and HDD 32 (address 006): 3 hours.

If the HDD selection condition is to select the HDD with the longest remaining recordable time, the program reservation at 7:00 is performed by selecting the HDD 12 with the longest remaining recordable time. When recording of the tuner 21 is started at 8:00, the following information is transmitted to the controller 16.
HDD 12 (address 004): * In use (remaining recording time: 4 hours)
HDD 22 (address 005): 2 hours HDD 32 (address 006): 3 hours Here, since the HDD 12 has recorded for 1 hour with the tuner 11, the remaining recordable time is 4 hours.

  The controller 16 selects the HDD 12 with the longest remaining recordable time from the transmitted remaining recordable time, HDD12 (address 004): 4 hours, HDD22 (address 005): 2 hours, HDD32 (address 006): 3 hours. And record. That is, programs of the tuner 11 (3 hours out of 4 hours) and the tuner 21 (2 hours) are simultaneously written in the HDD 12.

  Next, at 10 o'clock, the remaining recordable time of the HDD 12 written simultaneously by the tuner 11 and the tuner 21 becomes zero. The HDD 12 transmits information for notifying the controller 16 that the remaining recordable time has become zero. The controller 16 that has received the transmission again acquires the remaining recordable time of all HDDs. The state of each tuner and each HDD at this time is shown below.

Tuner 11 (address 001): 1 hour (3 hours out of 4 hours recorded)
Tuner 21 (address 002): 0 hour (2 hours recorded)
Tuner 31 (address 003): 1 hour (unrecorded)
HDD 12 (address 004): 0 (5 hours-3 hours-2 hours) HDD 22 (address 005): 2 hours HDD 32 (address 006): 3 hours

From such a state, the controller 16 selects the HDD 32 having the longest remaining recordable time and performs recording. At the same time, when the recording of the tuner 31 is started, the following information is transmitted to the controller 16.
HDD 12 (address 004): 0 hour HDD 22 (address 005): 2 hours HDD 32 (address 006): * In use (remaining recordable time: 3 hours)

  The controller 16 selects and records the HDD 32 having the longest remaining recordable time. That is, the programs of the tuner 11 (1 hour remaining) and the tuner 31 (1 hour) are simultaneously written in the HDD 32. Finally, when all the recordings are finished, the state of each HDD is as follows: HDD 12 (address 004): 0 hour, HDD 22 (address 005): 2 hours, HDD 32 (address 006): 1 (3 hours-1 hour) -1 hour) hours.

  Now, when recording a program at home, a combination of a plurality of existing tuners and recording media, selecting a combination that can record the program most efficiently, and recording the program, the user can further program If the remaining recordable time of all recording media in the home becomes zero, the program cannot be recorded any more.
