Description

Information processing apparatus and information processing program

Technical field

[0001] The present application belongs to the technical field of an information processing apparatus and an information processing program. More specifically, for example, the present application performs information processing such as recording on broadcast information transmitted via broadcast radio waves and the like. It belongs to the technical field of an information processing apparatus that performs necessary information processing on already acquired information and an information processing program used for the information processing. Background art

[0002] In recent years, broadcast information such as programs broadcast via broadcast radio waves has been received, and this is received as a DVD.

An information recording apparatus such as a so-called hard disk recorder for recording on a recording medium such as a (Digital Versatile Disc) or a hard disk is becoming popular.

[0003] On the other hand, in the hard disk recorder, it is often possible to copy information between different recording media (so-called dubbing processing, ripping processing, etc.).

[0004] Here, in the broadcast information reception process described above, the schedule is determined based on the broadcast schedule at an external broadcasting station. As a user who receives the schedule, for example, the broadcast start time It is necessary to make a reservation for the scheduled recording process including settings such as (= recording start time), receive the broadcast information by reservation, and record it.

[0005] On the other hand, in the above information copying process, a certain amount of time is often required depending on the transfer rate.

[0006] When the broadcast information reception process and the information copy process are performed using a single hard disk recorder, the time required for the broadcast information reception process and the time required for the information copy process overlap. There may be cases.

[0007] With regard to this point, conventionally, in many cases, the copying process of information set by the user himself / herself is prioritized over the broadcast information receiving process. In many cases, the broadcast information reception process is not started unless the process is completed. [0008] In addition, as described in Patent Document 1 below, as another prior art, when the time required for the broadcast information reception processing and the time required for the information copy processing overlap, the user is notified. It is configured to issue a warning to the user and select which process to execute.

[0009] Further, as another conventional technique described in Patent Document 2 below, two hard disk recorders are connected using a network, and the time required for receiving broadcast information and the time required for copying information In such a case, one hard disk recorder performs broadcast information reception processing, and the other hard disk recorder performs information copying processing.

Disclosure of the invention

Problems to be solved by the invention

[0010] However, in the conventional techniques other than Patent Document 1 and Patent Document 2 described above and the technique described in Patent Document 1, the time required for receiving broadcast information and the time required for copying information overlap. However, there is no change in that only one of the processes can be executed.

[0011] In addition, the technique described in Patent Document 2 requires at least two hard disk recorders, which has a problem in that the cost, installation space, and operation become complicated.

[0012] Therefore, the present application has been made in view of the above-described problems, and an example of the problem is a scheduled execution time for receiving processing of broadcast information or the like with a simple configuration and reducing costs. The present invention provides an information processing apparatus and an information processing program that can be executed in a balanced manner even when the execution time of a copy process or the like overlaps.

BEST MODE FOR CARRYING OUT THE INVENTION

Next, the best mode for carrying out the present application will be described with reference to the drawings. In the embodiment described below, broadcast information (specifically, image information or audio information) broadcasted via a television broadcast radio wave is stored (reserved) in advance and received. The present application is applied to an information recording apparatus capable of both a scheduled recording process for recording and a so-called dubbing process in which recorded information is copied from an external or other recording medium provided in the same apparatus. This is an embodiment when applied.

[0018] (D i m

First, a first embodiment according to the present application will be described with reference to FIGS.

FIG. 1 is a block diagram showing a schematic configuration of the information recording apparatus according to the first embodiment, FIG. 2 is a flowchart showing the operation of the information recording apparatus, and FIG. FIG.

As shown in FIG. 1, the information recording apparatus S according to the first embodiment includes a pickup 2, an A / D (analog / digital) converter 3, and an MPEG (Moving Picture Expert Group) as a processing means. Encoder 4, recording encoder 6 as processing means, recording circuit 7, MPEG decoder 11, DZA converter 13, spindle motor 16, overlap detection means, scheduled end time detection means and CPU 17 as control means And a servo circuit 18, a display unit 19 as a notification unit, and an operation unit 20 as an externally dependent processing time setting unit.

Next, the general operation of each component will be described with reference to FIG.

First, as the reservation recording process according to the first embodiment, the broadcast information received via a broadcast radio wave (not shown) such as an externally connected V, television tuner, etc. Specifically, as described above, both image information and audio information are included) will be described in the case of recording on the optical disc 1 as a recording medium.

[0022] First, on the premise that the reserved recording process is performed, the operation unit 20 records the broadcast start time and the broadcast end time of the broadcast information, the broadcast channel, and the optical disc 1 as the target of the reserved recording process. Recording rate (in other words, the image at the time of recording) And the like are input to the CPU 17 as the instruction signal Sc. Then, the CPU 17 stores information indicating the broadcast start time in a nonvolatile manner, and when the broadcast start time approaches, the initialization process set in advance for recording on the optical disc 1 is performed. Each constituent member is controlled so that the above-described constituent members are executed.

[0023] Then, when the operation for the reservation recording process described above is completed and the broadcast start time has arrived, the information signal Sin corresponding to the broadcast information is input by the television tuner or the like (not shown). First, the AZD converter 3 digitizes the information signal Sin, generates a digital signal Sd, and outputs it to the MPEG encoder 4.

Then, the MPEG encoder 4 is based on the control signal S output from the CPU 17.

7, the input digital signal Sd is compressed by, for example, the MPEG2 system, and the compressed signal Se is generated and output to the recording encoder 6 and the MPEG decoder 11.

Thus, the recording encoder 6 is based on the control signal S output from the CPU 17.

Three

The input compressed signal Se is subjected to a so-called formatting process for converting the current format of the compressed signal Se into a format for recording on the optical disc 1 to generate a recording encoded signal Sre to generate a recording circuit 7 Output to.

In parallel with this, the recording encoder 6 is based on the control signal S, and if necessary,

Three

A recording address signal Sra indicating a position on the optical disk 1 of a recording signal Sr to be recorded later (that is, a position on the optical disk 1 on which the information to be recorded is recorded) to be recorded based on the generated recording encoding signal Sre. Is output to CPU 17.

Next, the recording circuit 7 is input based on the control signal S output from the CPU 17.

2

The incoming recording encode signal Sre is converted into a recording signal Sr for recording and output to pickup 2. At this time, in the recording circuit 7, so-called write strategy processing or the like is performed on the recording encode signal Sre that forms a pit having a shape accurately corresponding to the information to be recorded on the optical disk 1 described later.

Thereafter, the pickup 2 drives a light source such as a semiconductor laser (not shown) in the pickup 2 based on the recording signal Sr output from the recording circuit 7 to generate a light beam B such as a laser beam. Irradiate the information recording surface of optical disc 1 and respond to the recording signal Sr The recording signal Sr is recorded on the optical disk 1 by forming pits to be recorded.

At this time, the optical disc 1 is rotated at a predetermined rotational speed by a spindle motor 16 driven based on a spindle control signal Ssm described later. On the optical disk 1, for example, pits corresponding to the recording signal Sr are formed by the phase change method, and the recording signal Sr is recorded.

On the other hand, the MPEG decoder 11 is based on the control signal S output from the CPU 17.

9

The compressed signal Se that has been input is expanded by the MPEG2 method and output to the DZA converter 13 as a decoded signal Sdc.

[0031] Next, the DZA converter 13 analogizes the decoded signal Sdc, generates an output signal Sout corresponding to the information signal Sin, and outputs the output signal Sout to an external monitor (not shown) or a speech force (not shown).

At this time, the CPU 17 should execute the reserved recording process based on the broadcast start time and broadcast end time of the stored broadcast information, the broadcast channel, the recording rate, the recording address signal Sra, and the like. The above control signals S, S, S and S are generated.

2 3 7 9

Then, each operation for recording is controlled by outputting to each of the constituent members.

[0033] By the series of information recording operations described above, an image or sound corresponding to the currently recorded recording signal Sr can be recorded while monitoring in real time.

[0034] Next, as the dubbing process according to the first embodiment, information externally connected and input from another information reproducing device (not shown) or other recording (not shown) in the information recording device S The processing in the case of recording information on the optical disk 1 recorded on a medium (for example, a hard disk on which information is recorded using magnetism) will be described.

Note that information from the other information reproducing apparatus or the other recording medium is input to the AZD converter 3 as the information signal Sin.

When a dubbing start button (not shown) is operated on the operation unit 20 when starting the dubbing process, the AZD converter 3, MPEG encoder 4, recording encoder 6, recording circuit 7, The pickup 2, the MPEG decoder 11 and the DZA converter 13 perform the same operation as in the above-described reservation recording process, and record the recording signal Sr corresponding to the information signal Sin to be dubbed on the optical disc 1 on the optical disc 1. And currently recorded An image or sound corresponding to the recording signal Sr is output as an output signal Sout to an external monitor (not shown) or a speaker (not shown).

At this time, the CPU 17 generates the control signals S, S, S, and S to execute the dubbing process based on the recording address signal Sra and the like, and outputs the control signals S to the constituent members.

2 3 7 9

Thus, each operation for recording described above is controlled.

[0038] In parallel with each operation of the reservation recording process or dubbing process, the CPU 17 generates a control signal Ss for servo-controlling the spindle motor 16 and the pickup 2 and outputs the control signal Ss to the servo circuit 18. The servo circuit 18 generates the spindle control signal Ssm for controlling the rotation of the spindle motor 16 based on the control signal Ss and outputs the spindle control signal Ssm to the spindle motor 16. A pickup control signal Ssp for focus servo control is generated and output to the pickup 2 concerned. The pickup 2 records the recording signal Sr while performing tracking servo control and focus servo control on the light beam B based on the pickup control signal Ssp.

Note that information necessary for the user to control the operation of the information recording apparatus S described above is displayed on the display unit 19 based on the display signal Sdp from the CPU 17.

[0040] In the dubbing process described above, the operation of each component for the dubbing process accompanied by the formatting process in the MPEG encoder 4 has been described. As the dubbing process according to the first embodiment, In addition to the above, the MPEG encoder 4 and the recording encoder 6 are not used (that is, the format in the information to be dubbed inputted as the information signal Sin is used when information is already recorded on the optical disc 1. There is a dubbing process that is in line with the recording format to be recorded, and it is necessary to convert the data rate for the recording process. . When this dubbing process is executed, the digital signal Sd digitized by the AZD converter 3 passes through the MPEG encoder 4 and the recording encoder 6 and is output to the recording circuit 7 as it is.

[0041] It should be noted that the dubbing process without using the MPEG encoder 4 and the recording encoder 6 In this case, even when the MPEG encoder 4 and the recording encoder 6 are used in the reservation recording process, the reservation recording process and the dubbing process can be simultaneously performed in parallel. In this case, in the recording circuit 7 and the pickup 2, the reserved recording process and the dubbing process are executed in a time division manner.

[0042] Next, the dubbing process and the reserved recording process according to the first embodiment, which are executed in the information recording apparatus S having the above-described configuration, are specifically shown in FIGS. Will be described. In the operation described below, an information recording apparatus S including a plurality of sets of MPEG encoders 4 and recording encoders 6 and only one set of them is described. Also, various information indicating the broadcast start time and broadcast end time, broadcast channel, and recording rate at the time of recording on the optical disc 1 necessary for the reservation recording process are already stored in the CPU 17 in a nonvolatile manner by a known method. It shall be.

[0043] As shown in FIG. 2, when the operation unit 20 instructs the start of the dubbing process according to the first embodiment in a state where the above-described various information necessary for the reservation recording process is stored in the CPU 17 (Step S1). ), It is determined whether or not the dubbing process requires a coding process by the MPEG encoder 4 and the recording encoder 6 (step S2). The determination in step S2 is whether the recording rate specified by the user is different from the data rate as the information signal Sin, or whether the remaining recordable capacity on the optical disc 1 and the information signal Sin to be recorded are Based on the relationship with the total amount of information, etc., the CPU 17 determines.

[0044] When the dubbing process to be executed is a dubbing process that does not use the MPEG encoder 11 and the recording encoder 6 in the determination in step S2 (step S2; NO), it is necessary to use the recording circuit 7 as it is. Start a dubbing process (step S9).

[0045] Then, during the execution of the dubbing process !, it is always confirmed whether or not all the necessary dubbing processes have been completed (step S10). (Step S10; YES) If the operation according to the first embodiment is finished as it is, but all the necessary dubbing processes have not been completed yet (Step S10; NO), the process returns to Step S9 to perform the necessary dubbing process. Continue.

On the other hand, when the dubbing process to be executed is a dubbing process that requires the use of the MPEG encoder 11 and the recording encoder 6 in the determination in step S2, ( (Step S2; YES) Next, a time for performing the dubbing process instructed in Step SI (hereinafter, simply referred to as dubbing time) is calculated, and at least a part of the calculated dubbing time is calculated. At least a part of the time at which the above-described reserved recording process is executed (that is, the time from the broadcast start time to the broadcast end time stored in the CPU 17; hereinafter, the time is simply referred to as a reserved recording time) (Steps S3 and S4).

[0047] If there is no overlap (step S4; NO), it is not necessary to use the MPEG encoder 6 and the recording encoder 7 redundantly. Even if the dubbing process is started immediately, the scheduled recording process is affected. Therefore, the necessary dubbing process is started using the recording circuit 7 or the like as it is (step S9), and the operation proceeds to step S10 described above.

[0048] On the other hand, if there is at least some overlap between the scheduled recording time and the dubbing time in the determination in step S4 (step S4; YES), this is displayed on the display unit 19. If the dubbing process is started after the scheduled recording process is completed, the scheduled end time of the dubbing process is calculated and displayed, and the dubbing process is performed after the scheduled recording process is completed. Is displayed (step S5).

[0049] Then, the display contents, that is, whether or not an operation indicating that the user has accepted that the dubbing process starts after the reserved recording process is completed is confirmed in the operation unit 20 ( Step S6) When the operation is executed (Step S6; YES), first, the scheduled recording process is executed based on the broadcast start time stored in the CPU 17 (Step S11), After that, the process proceeds to step S9 to execute the dubbing process (step S9), and further proceeds to the operation of step S10 described above.

[0050] On the other hand, in the determination in step S6, when an operation indicating that the user does not accept that the dubbing process is started after the reserved recording process is completed is performed on the operation unit 20 (step S6; NO) Therefore, it is determined that it is not necessary to execute part of the scheduled recording process due to the execution of the dubbing process, and then confirms with the user whether or not the user can immediately start the dubbing process (step S7). . Then, when an operation to the effect that the user has approved to start the dubbing process immediately is executed on the operation unit 20 (step S 8; YES), the desired dubbing process is immediately performed (step S9), and after the completion, the process proceeds to step S10.

On the other hand, when it is determined in step S8 that the operation unit 20 is instructed not to start the dubbing process immediately (step S8; NO), the process proceeds to step S10 as it is.

Next, the execution mode of the dubbing process and the reserved recording process according to the first embodiment shown in FIGS. 1 and 2 will be specifically described with reference to FIG.

First, in FIG. 3, the scheduled recording time P is from the broadcast start time T to the broadcast end time T.

On the other hand, dubbing time P is dubbing end time from dubbing start time T

E D DS

Suppose it is up to T. And both are the end of the dubbing time P and the scheduled recording time.

DE D

Suppose that the beginning of P overlaps by time D.

[0054] When the dubbing process and the scheduled recording process according to the first embodiment are executed in such a state, if it is "YES" in the determination of step S6, the bottom part of FIG. Thus, after all the reserved recording processes are completed, the dubbing process is started immediately and the necessary dubbing process is executed.

[0055] As described above, according to the operation of the information recording apparatus S according to the first embodiment, there is a time interval between at least a part of the reserved recording time and at least a part of the dubbing time. When there is an overlap, control is performed so that the dubbing process is executed at times other than the scheduled recording time, so that a simple configuration using a single information recording device S can be performed without any user intervention. The recording process and the dubbing process can be executed at the same time.

[0056] Therefore, it is possible to execute both of the scheduled recording time and the dubbing time in a simple operation and configuration while reducing costs and the like even when the reserved recording time and the dubbing time overlap.

[0057] Furthermore, since the scheduled end time of the dubbing process is notified, the convenience can be further improved.

[0058] (II) Second Embodiment

Next, a second embodiment, which is another embodiment according to the present application, will be described with reference to FIGS. FIG. 4 is a flowchart showing the operation of the information recording apparatus according to the second embodiment, and FIG. 5 is a conceptual diagram specifically explaining the operation. [0059] In the first embodiment described above, when there is at least some overlap between the scheduled recording time and the dubbing time, the scheduled recording process is executed first, and the dubbing is performed after the completion. In the second embodiment described below, when the dubbing process is started earlier than the scheduled recording process and there is an overlap, the dubbing process is started as scheduled. After that, the time required to start the reserved recording process from the start time of the scheduled recording process (that is, the broadcast start time stored in the CPU 17) (hereinafter referred to as the preparation time) The dubbing process is temporarily interrupted at the timing just before (time), and then the scheduled recording process is executed after the preparatory process. Interrupted timing power resumes of its a ring processing.

[0060] Further, since the information recording apparatus according to the second embodiment has the same configuration as that of the information recording apparatus S according to the first embodiment shown in FIG.

Next, the dubbing process and the reserved recording process according to the second embodiment will be specifically described with reference to FIGS. 4 and 5. FIG. In the operation described below, as in the case of the first embodiment, the broadcast start time and broadcast end time, the broadcast channel, and the recording rate at the time of recording on the optical disc 1 are shown. It is assumed that various information is already stored in the CPU 17 in a nonvolatile manner by a known method. In the flowchart shown in FIG. 4, the same steps as those in the dubbing process and the scheduled recording process according to the first embodiment shown in FIG.

[0062] As shown in FIG. 4, when the operation unit 20 is instructed to start the dubbing process according to the second embodiment in a state where the above-described various information necessary for the reservation recording process is stored in the CPU 17 (step S1 Thereafter, the same processing as steps S2 to S4 shown in FIG. 2 is executed.

[0063] If it is determined in step S4 that there is at least a part of overlap between the reserved recording time and the dubbing time (step S4; YES), next, the second embodiment will be described.

Of the information signal Sin, the portion of the information signal Sin that can complete the dubbing process from the broadcast start time, which is the start time of execution of the reserved recording process, to the timing before the preparation time is calculated (step S15). ). [0064] After that, as processing similar to step S5 shown in FIG. 2, it is displayed that there is at least a part of overlap between the reserved recording time and the dubbing time, and the dubbing processing is temporarily interrupted to make a reservation. Displays that the remaining dubbing process is to be resumed after executing the recording process, and further performs the dubbing process up to the part calculated in step S15 before executing the scheduled recording process, and then temporarily stops the dubbing process. The scheduled recording process is executed, and then the dubbing process that has been temporarily suspended is calculated and displayed when the position of the information signal Sin that has been temporarily resumed is resumed (step S5). Then, the user acknowledges that the displayed content, that is, the dubbing process is temporarily suspended and the remaining dubbing process is resumed after executing the reserved recording process. It is confirmed whether or not the operation has been executed in the operation unit 20 (step S6). When the operation is not executed (step S6; NO), the processing of steps S7 to S10 shown in FIG. 2 is subsequently executed. .

[0065] On the other hand, in the determination in step S6, the operation indicating that the user has accepted that the dubbing process is temporarily suspended and the remaining recording process is started after executing the reserved recording process is performed on the operation unit. If executed in step 20 (step S6; YES), the dubbing process is started from the scheduled start time of the dubbing process (step S16), and after the start, in step S15 above. It is monitored whether or not the dubbing process has been completed up to the calculated information signal Sin (step S17). Then, the dubbing process up to the relevant part (that is, the part where the dubbing process is scheduled to be interrupted) is completed. If not (step S17; NO), the process returns to step SI6 and the dubbing process is continued up to the part scheduled for interruption. On the other hand, when the dubbing process is completed up to the scheduled interruption part (step S17; YES), the reserved recording operation is started from the broadcast start time (step S13).

[0066] After the reservation recording process is started, it is monitored whether or not the reservation recording process has been completed (step S18). If the scheduled recording process has not been completed (step S18; NO), the process returns to step S17 to continue the scheduled recording process. On the other hand, if the scheduled recording process has been completed (step S18; YES) Then, the process of step S17 is temporarily interrupted and the rest of the dubbing process is resumed, and the entire dubbing process is completed (step S19). Thereafter, the process proceeds to step S10. Next, the execution mode of the dubbing process and the scheduled recording process according to the second embodiment shown in FIG. 4 will be specifically described with reference to FIG.

[0070] After the interruption of the dubbing process, the preparation process necessary for starting the reservation recording process is executed during the preparation time, and the reservation recording process is started. Then, after all the scheduled recording processes are completed, the rest of the dubbing process (the required time is the dubbing time P shown in Fig. 5) is resumed and all necessary dubbing processes are executed. .

D2

[0071] As described above, even in the case of the operation of the information recording apparatus according to the second embodiment, there is a temporal difference between at least a part of the reserved recording time and at least a part of the dubbing time. When there is an overlap, control is performed so that the dubbing process is executed at a time other than the scheduled recording time, so the scheduled recording process and the simple configuration using one information recording device can be performed without any user intervention. The dubbing process can be executed at the same time, and it is possible to execute both the scheduled recording time and the dubbing time at the same time while reducing the cost and the like with a simple operation and configuration and reducing the cost. it can.

[0072] Further, since the scheduled end time of the dubbing process is notified, the convenience can be further improved.

[0073] Furthermore, when there is the overlap, the execution of the dubbing process is temporarily interrupted by the time when the reservation recording process is started, and the execution of the interrupted dubbing process is resumed after the reservation recording process ends.

In the operation described below, as in the case of the first and second embodiments, the broadcast start time and broadcast end time, the broadcast channel, and the recording rate for recording on the optical disc 1 necessary for the above-described reservation recording process Indicate It is assumed that the various information is already stored in the CPU 17 in a nonvolatile manner by a known method. Also, in the flowchart shown in FIG. 6, the same step numbers are assigned to the same processes as the dubbing process and the scheduled recording process according to the first embodiment shown in FIG. Is omitted.

[0079] As shown in FIG. 6, when the start of the dubbing process according to the third embodiment is instructed in the operation unit 20 in a state where the various information necessary for the reservation recording process is stored in the CPU 17 (step S1 Thereafter, the same processing as steps S2 to S4 shown in FIG. 2 is executed.

[0080] Then, in the determination in step S4, if there is at least a part of overlap between the reserved recording time and the dubbing time (step S4; YES), next, the third embodiment relates.

In the information signal Sin, the time before the start of the preparatory time B from the broadcast start time T, which is the execution start time of the scheduled recording process, is

RS 1

A portion corresponding to the last unit information (for example, a chapter) in the information signal Sin that can complete the bing process is calculated (step S20).

[0081] After that, as processing similar to step S5 shown in FIG. 2, it is displayed that there is at least a part of overlap between the reserved recording time and the dubbing time, and the dubbing processing is temporarily suspended to make a reservation. Displays that the remaining dubbing process will be resumed after executing the recording process, and further performs the dubbing process up to the part calculated in step S20 before executing the scheduled recording process, temporarily suspends the dubbing process, and then reserves The recording process is executed, and then the dubbing process that has been temporarily suspended is calculated and displayed when the position force of the temporarily interrupted information signal Sin is resumed (step S5).

[0082] Then, the operation unit 20 performs an operation indicating that the display content, that is, the user's consent to resume the remaining dubbing process after the dubbing process is temporarily suspended and the reserved recording process is performed. If the operation is not executed (step S6; NO), the processing of steps S7 to S10 shown in FIG. 2 is executed thereafter.

[0083] On the other hand, in the determination in step S6, the operation indicating that the user has accepted that the dubbing process is temporarily suspended and the remaining dubbing process is started after executing the reserved recording process. Is executed at the operation unit 20 (step S6; YES), the dubbing process is started from the scheduled start time of the dubbing process (step S16), and the calculation is performed in step S20 after the start. It is monitored whether or not the dubbing process is completed until the last unit information portion in the information signal Sin (step S17). If the dubbing process up to the relevant part (that is, the part where the dubbing process is scheduled to be interrupted) should be completed (step S17; NO), return to step S16 and continue the dubbing process up to the part to be interrupted. On the other hand, when the dubbing process is completed up to the scheduled interruption portion (step S17; YES), the broadcast start time T is then started for the reserved recording operation (step S13).

RS

[0084] After the reservation recording process is started, it is monitored whether or not the reservation recording process has been completed (step S18). If the scheduled recording process has not been completed (step S18; NO), the process returns to step S17 to continue the scheduled recording process. On the other hand, if the scheduled recording process has been completed (step S18; YES) Then, the process of step S17 is temporarily interrupted and the rest of the dubbing process is resumed, and the entire dubbing process is completed (step S19). Thereafter, the process proceeds to step S10.

Next, the execution mode of the dubbing process and the scheduled recording process according to the third embodiment shown in FIG. 6 will be specifically described with reference to FIG.

It will be awkward to be executed.

[0089] As described above, even in the case of the operation of the information recording apparatus according to the third embodiment, there is a temporal difference between at least a part of the reserved recording time and at least a part of the dubbing time. When there is an overlap, control is performed so that the dubbing process is executed at a time other than the scheduled recording time, so the scheduled recording process and the simple configuration using one information recording device can be performed without any user intervention. The dubbing process can be executed at the same time, and it is possible to execute both the recording time and the dubbing time at the same time while reducing the cost and the like with a simple operation and configuration and reducing the cost. it can.

[0090] Furthermore, since the scheduled end time of the dubbing process is notified, the convenience can be further improved.

[0091] Further, when there is an overlap, the execution of the dubbing process is temporarily interrupted by the time when the reserved recording process is started, and the interrupted dubbing process is resumed after the reserved recording process is completed. Scheduled recording processing and dubbing processing can be executed in a balanced manner.

[0092] Furthermore, since the dubbing process is interrupted after the unit information as a unit of information to be dubbed is completed, and the dubbing process is resumed from the next unit information of the unit information after the reserved recording process is completed. The scheduled recording process and the dubbing process can be made compatible without unnaturally ending the dubbing process for the information to be dubbed.

Using the result, among the information signals Sin that will be the target of the dubbing process according to the fourth embodiment next, from the timing that is earlier than the broadcast start time T by the interruption time B. A portion corresponding to the last unit information (for example, chapter) in the information signal Sin that can complete the dubbing process before is calculated (step S20).

[0099] After that, the same processing as step S5 according to the third embodiment shown in FIG. 6 is performed, and the display content, that is, the dubbing process is temporarily interrupted and the reserved recording process is executed, and then the remaining dubbing process is resumed. Confirm that the operation that indicates that the user has accepted is performed in the operation unit 20 (step S6) .If the operation is not performed (step S6; NO), the dubbing process is performed. The dubbing process currently in progress is continued because it is not permitted to interrupt the process, and then the process of step S10 shown in FIG. 2 is executed.

[0100] On the other hand, in the determination of step S6, an operation indicating that the user has accepted that the dubbing process is temporarily suspended and the remaining recording process is started after executing the reserved recording process is performed on the operation unit 20. (Step S6; YES), continue the current dubbing process (Step S32), and after the start, the operations of Steps S17, S13, SI 8 and SI 9 shown in Fig. 6 After that, the process proceeds to step S10.

Next, the execution mode of the dubbing process and the scheduled recording process according to the fourth embodiment shown in FIG. 8 will be specifically described with reference to FIG.

[0105] As described above, even in the case of the operation of the information recording apparatus according to the fourth embodiment, there is a temporal difference between at least a part of the reserved recording time and at least a part of the dubbing time. When there is an overlap, control is performed so that the dubbing process is executed at a time other than the scheduled recording time, so the scheduled recording process and the simple configuration using one information recording device can be performed without any user intervention. The dubbing process can be executed at the same time, and it is possible to execute both the recording time and the dubbing time at the same time while reducing the cost and the like with a simple operation and configuration and reducing the cost. it can.

[0106] Further, since the scheduled end time of the dubbing process is notified, the convenience can be further improved.

[0107] Further, when there is the overlap, the execution of the dubbing process is temporarily interrupted by the time when the reservation recording process is started, and the execution of the interrupted dubbing process is resumed after the reservation recording process ends. Scheduled recording processing and dubbing processing can be executed in a balanced manner.

[0108] Furthermore, since the dubbing process is interrupted after the unit information as a unit of information to be dubbed is completed, and the dubbing process is resumed from the next unit information of the unit information after the reserved recording process is completed. The scheduled recording process and the dubbing process can be made compatible without unnaturally ending the dubbing process for the information to be dubbed.

[0109] Further, even when the necessity of the reserved recording process occurs after the start of the dubbing process, both can be surely made compatible.

Note that, as a dubbing process interruption method according to the fourth embodiment, it is needless to say that the dubbing process interruption method according to the second embodiment considering only the preparation time B can be used. [0111] Further, in each of the embodiments described above, the power described for each of the cases in which the scheduled recording process and the dubbing process overlap in time, other than this, the reserved recording process and so-called rubbing process (music information It is also possible to apply the present application when the target dubbing process) overlaps in time.

Furthermore, as the dubbing process according to the present application, the dubbing process according to each of the above-described embodiments is performed.
