  The operation unit 8 is a collection unit such as the buttons 8a to 8g provided on the apparatus main body side (housing 2) shown in FIGS. 1 and 2, and the buttons constituting the operation unit 8 are operated by the user. An operation signal assigned to the button is transmitted to the control unit 20. In addition, the ROM 31 stores in advance a program for the control unit 20, menu image data for OSD, a threshold value for determination processing, a reference value, and the like. The content (data) processed by the control unit 20 is temporarily recorded in the RAM 32. Further, the B-cas card reading unit 33 reads the recorded content of the B-cas card inserted into the slot unit 10 shown in FIG. 2 and sends the read content to the control unit 20.

  Next, the operation mode of the recording apparatus 1 based on the control process of the control unit 20 will be described. First, when data is moved (including copying) between each recording medium or between the recording medium and an external device as the dubbing process, the control unit 20 displays the first menu image 50 shown in FIG. Control is performed to output the data for use from the external output unit 24 (see FIG. 4), and the first menu image 50 is displayed on the screen of a television device (not shown) connected to the recording device 1. When the first menu image 50 is displayed, the user operates the remote controller 40 to select a dubbing source from items such as “HDD”, “BD”, “DVD”, and “IEEE1394”. Upon receiving an operation signal related to an instruction to select a dubbing source from the remote control light receiving unit 7, the control unit 20 next performs a process of displaying a menu image for accepting designation of a dubbing destination.

  FIG. 7A shows the second menu image 51 displayed when “HDD” is selected as the dubbing source. When the second menu image 51 is displayed, the user performs an operation of selecting a dubbing destination from “BD”, “DVD”, “IEEE1394”, and “automatic” using the remote control device 40. When the control unit 20 receives an operation signal related to an instruction to select a dubbing destination from the remote control light receiving unit 7, the user selects data to be dubbed from data recorded in the dubbing source hard disk device 17. Accordingly, dubbing processing related to data movement is started.

  When “automatic” is selected in the second menu image 51, the control unit 20 specifies the optimum dubbing destination for the data selected by the user as the dubbing target, and performs dubbing processing of the data to the specified dubbing destination. Do. The process of specifying the dubbing destination by the control unit 20 is performed based on the detection result of the data type, the data amount, etc. For example, when the data amount to be dubbed exceeds the recording capacity of “DVD”, the dubbing destination is “ “BD” is specified, and if the type of data is recorded high-definition broadcast, since the number of times of movement is one, “BD” is specified as the dubbing destination so that dubbing can be performed reliably. Further, when the data type is recorded analog broadcast and the data amount is within the recording capacity of “DVD”, “DVD” is specified as the dubbing destination.

  FIG. 7B shows a third menu image 52 displayed when “BD” is selected as the dubbing source. When the third menu image 52 is displayed, the user uses the remote control device 40. To select a dubbing destination from “HDD”, “DVD”, and “IEEE1394”. After selecting the dubbing destination, the dubbing process is started by selecting the data to be dubbed, as in the case of “HDD”.

  FIG. 7C shows a fourth menu image 53 displayed when “DVD” is selected as the dubbing source. When the fourth menu image 53 is displayed, the user uses the remote control device 40. To select the dubbing destination from “HDD”, “BD”, and “IEEE1394”. Further, FIG. 7D shows a fifth menu image 54 displayed when “IEEE1394” is selected as the dubbing source. When the fifth menu image 54 is displayed, the user uses the remote control device 40. To select a dubbing destination from “HDD”, “BD”, and “DVD”. Even when “DVD” and “IEEE 1394” are dubbing sources, after selecting a dubbing destination, data is selected and dubbing is performed in the same manner as described above.

  When the control unit 20 performs the control as described above for the dubbing process, the recording apparatus 1 of the present embodiment has “BD”, “DVD”, “HDD (hard disk device 17)”, and “IEEE1394 (IEEE1394 terminal unit 9). ) "In both directions, and as a result, recording in a total of 12 directions is realized. When “BD” and “DVD” are selected as the dubbing source and the dubbing destination, the control unit 20 uses the first optical pickup unit 13 of the BD drive unit 28 and the second optical pickup unit 15 of the DVD drive unit 29 to perform BD. , It is detected whether the DVD is placed on each tray 11, 12. When it is detected that the DVD is not placed, a caution image with a content such as “Please set disc” is connected. The data is displayed on a display device (not shown).

  In the dubbing process related to “IEEE1394” related to the external device, the pattern in which the dubbing source is “IEEE1394” and the dubbing destination is “BD” and “HDD” is BD and HDD (hard disk device 17 ) Is a recording medium having a large recording capacity, and is suitable for dubbing a large amount of data from an external device. Further, when the dubbing source is “HDD” and the dubbing destination is “IEEE1394”, various data recorded by the recording device 1 is recorded on the HDD (hard disk device 17). It becomes important in the point utilized in the equipment of.

  FIG. 8 shows a sixth menu image 55 that is displayed when the recording apparatus 1 performs the reservation recording process under the control of the control unit 20. When performing scheduled recording, the sixth menu image 55 is displayed after a program to be recorded is selected using an electronic program guide recorded in the hard disk device 17 or the like in advance, and “HDD”, “ The user selects an item desired by the user from among the items "BD", "DVD", "IEEE1394", "Automatic", and "Continuous", and the control unit 20 generates an operation signal for instructing the selected item. It is received from the remote control light receiving unit 7 or the operation unit 8. After that, when the recording mode or the like is selected by the user and the reservation is completed, the control unit 20 receives at any one of the tuner units 21 to 23 in accordance with the broadcast time of the reserved program, and at the selected recording destination. Record the received content data.

  In the normal recording process, the user can select the recording destination according to the sixth menu image 55. However, when “HDD”, “BD”, and “DVD” are selected as the recording destination, FIG. Selection instructions can be given to the control unit 20 by operating the changeover switches 8c to 8e shown or the changeover buttons 41 to 43 of the remote control device 40 shown in FIG. Further, when “BD” or “DVD” is selected as the recording destination, data is directly recorded on a BD or DVD which is a removable recording medium suitable for data storage. Compared to recording, it is preferable to omit the dubbing process.

  When “automatic” is selected in the sixth menu image 55 of FIG. 8, the control unit 20 specifies “BD” or “DVD” as a recording destination in accordance with a preselected recording target program. Specifically, the control unit 20 specifies the recording destination according to the data amount of the content data related to the program received by each tuner unit 21 to 23, the type of the program, the recording mode, and the like. If the program is a digital high-definition broadcast, “BD” is specified as the recording destination, and if the program to be recorded is an analog broadcast and the digital broadcast with a small amount of data is specified, “DVD” is specified as the recording destination. Further, when the program to be recorded exceeds the recording capacity of “DVD” for a very long time, the control unit 20 specifies “BD”, and when the program to be recorded is not a long time, it is a general recording mode. When the recording mode is long (SP mode) or when the recording mode is for a long time (LP or EP mode), the control unit 20 specifies “DVD” as the recording destination. Whether the recording time is long or not is determined by the control unit 20 based on the threshold value recorded in the ROM 31.

  As described above, when “automatic” is selected in the sixth menu image 55, either BD or DVD as a detachable recording medium is selected according to the recording contents, and this case is also suitable for storage. By recording directly on the recording medium, unnecessary dubbing processing can be eliminated.

  Furthermore, when “continuous” is selected in the sixth menu image 55 of FIG. 8, the control unit 20 continuously records in the order of BD (BD drive unit 28), hard disk device 17, and DVD (DVD drive unit 29). Process. The switching of the recording process is performed based on the free space of the BD and the DVD, the detection of the BD and the DVD, and the detection of whether or not the content data to be recorded is commercial. Specifically, when the BD drive unit 28 is recording on a BD, the control unit 20 detects whether or not the content data to be recorded is being commercialized using a data identifier, and detects that the content is being commercialized Detects the free capacity of the BD, and when the free capacity falls below the reference value recorded in the ROM 31, the recording destination is switched to the hard disk device 17 (HDD).

  Further, when the recording is switched to the hard disk device 17, if the DVD drive unit 29 completes the DVD recording preparation, the control unit 20 performs a process of switching the recording process to the DVD drive unit 29. Further, during the recording process to the DVD, it is detected whether or not the recording target is in the commercial state in the same manner as described above. If it is in the commercial state, the free space of the DVD is detected, and the free space is recorded in the ROM 31 as a reference value. If the value is less than, processing for switching the recording destination to the hard disk device 17 is performed. Furthermore, when the recording is switched to the hard disk device 17, when the BD drive unit 28 completes the preparation for recording the BD, the control unit 20 performs a process of switching the recording process to the BD drive unit 28. The above process is repeated until the process ends.

  In the above processing, when recording is switched to the hard disk device 17 due to a lack of free space, the recorded BD or DVD is taken out from the respective trays 11 and 12 by a user operation and replaced with a new one. Shall. In addition, when switching to the hard disk device 17, the switching time is recorded on the BD and DVD as a time stamp signal, and when the recording is switched from the hard disk device 17, the switching time is BD, The control unit 20 performs control so as to be recorded on the DVD. By recording the time stamp signal in this way, it becomes possible to distinguish the order of BD and DVD at the time of reproduction, and when an incorrect disc is set, the time stamp signal corresponding to the order is recorded. A process of notifying the user by the OSD so as to set things is performed.

The flowchart shown in FIG. 9 summarizes the processing procedure of the recording apparatus 1 when “continuous” is selected in the sixth menu image 55 of FIG. 8 described above. The flow of processing will be organized and explained. In this process, it is assumed that the program to be recorded and the recording mode have already been selected.
First, the recording apparatus 1 determines whether or not “continuous” is selected in the sixth menu image 55 and continuous recording is instructed (S1). If continuous recording has not been instructed (S1: NO), the instruction waits, and if continuous recording has been instructed (S1: YES), then the BD and DVD discs are set or the optical pickups 13 and 15 are used. Detection is performed (S2). When it is not possible to detect that each disk is set (S2: NO), the control unit 20 notifies the user that there is no disk (S3), and returns to the disk detection stage (S2). The notification to the user is continued until it is detected.

  On the other hand, when a set of each disk is detected (S2: YES), the recording device 1 starts the process of recording the received broadcast program content data on the BD when the program to be recorded is broadcast by the BD drive unit 28. (S4). During the reception of the broadcast, the control unit 20 of the recording device 1 determines whether or not the broadcast content is currently being commercial based on the identifier of the content data (S5). If it is determined that the commercial is not in progress (S5: NO), it is determined whether or not the program broadcast to be recorded ends and the recording ends (S6). When it is determined that the recording is not finished (S6: NO), the process returns to the determination step (S5) of whether or not the commercial is being performed.

  When it is determined that the commercial is being performed (S5: YES), the control unit 20 detects whether or not the free capacity of the BD is equal to or less than the reference value by the first optical pickup unit 13 (S7). If the free space is not less than the reference value (S7: NO), the process returns to the step of determining whether commercial is in progress (S5). If the free space is less than the reference value (S7: YES), the time according to the current time After the stamp signal is written to the BD, the recording is switched to the hard disk device (HDD) 17 (S8).

  Further, the control unit 20 detects whether or not the DVD drive unit 29 has completed the recording preparation for the DVD by the second optical pickup unit 13 (S9), and the preparation is not completed (S9: NO). Then, it is determined whether or not the recording is to be ended (S10). When it is determined that the recording is not to be ended (S10: NO), the process returns to the preparation completion detection stage (S9). The detection (S9) and the recording end determination (S10) are repeated. When the completion of the DVD recording preparation is detected (S9: YES), the recording process is switched to the DVD drive unit 29 and the time stamp signal related to the time of switching to the DVD is written to continue the recording (S11).

  Subsequently, the control unit 20 determines whether or not the broadcast content is currently being commercialized based on the identifier of the content data (S12). If it is determined that the broadcast content is not being commercialized (S12: NO), whether or not the recording is ended. Is determined (S13), and if it is determined that the recording is not finished (S13: NO), the process returns to the determination stage (S12) of whether or not the commercial is being performed. If it is determined that the commercial is being performed (S12: YES), the control unit 20 detects whether or not the free space of the DVD is equal to or less than the reference value by the second optical pickup unit 15 (S14). If it is not less than the reference value (S14: NO), the process returns to the step of determining whether commercial is in progress (S12). If the free space is less than the reference value (S14: YES), the time stamp signal relating to the current time is DVD Is switched to recording on the hard disk device (HDD) 17 (S15).

  Then, the control unit 20 detects whether or not the recording preparation for the BD is completed in the BD drive unit 28 (S16), and if the preparation is not completed (S16: NO), It is determined whether or not the recording is to be ended (S17), and when it is determined that the recording is not to be ended (S17: NO), the process returns to the preparation completion detection stage (S16), and the preparation completion is detected until the preparation is completed. (S16) and determination of recording end (S17) are repeated. Further, when the BD recording preparation completion is detected (S16: YES), whether or not the recording process is switched to the BD drive unit 28 and the time stamp signal related to the switching time is written to the BD to continue the recording. Returning to the determination step (S5), the above-described processing is repeated thereafter. Finally, when the control unit 20 determines that the recording is ended in any of the above-described determination steps (S6, 10, 13, 17) as to whether or not the recording is ended (S6, 10, 13, 17). : YES), all the recording processes are ended.

  The recording apparatus 1 performs continuous recording as described above, so that even a very long broadcast program can be recorded continuously on a plurality of BDs and DVDs, and recording switching between BDs and DVDs can be performed. Since the recording is basically performed during commercials, recording is directly performed on BD and DVD, which are recording media suitable for storage, without damaging substantial contents. Even when switching is not performed during a commercial, since the hard disk device 17 records the content at the time of switching in a buffer manner, the broadcast content is always recorded on the BD, DVD, or hard disk device 17. In addition, since time stamp signals are recorded on BDs and DVDs that have been recorded continuously, each disc is set in order according to the time sequence indicated by the time stamp signal, so that it can be played back in accordance with the contents of the broadcast program. Can be done.

  As described above, the recording apparatus 1 according to the embodiment of the present invention realizes various dubbing forms by making use of the characteristics of a BD having a large recording capacity, and a program with a large amount of data such as digital high-definition broadcasting and a long-time program. Can also be recorded directly on the BD, and can also be recorded in cooperation with other recording media such as DVD and HDD (hard disk device 17), so that various recording formats can be supported. . The recording apparatus 1 of the present invention is not limited to the above-described embodiment, and various modifications can be applied.

  For example, in the continuous recording process shown in the flowchart of FIG. 9, the DVD drive unit 29 can be changed to perform recording in the order of the hard disk device 17 and then the BD drive unit 28. In addition, the determination of the switching process is performed by detecting whether the scene of the broadcast content has been changed or the sound has become a stereo broadcast instead of whether the commercial is being performed or not. Also good.

  Further, as shown in the recording device 60 of the modified example of FIG. 10, a back surface portion 62b exposed by opening the panel 63 on the front surface 62a side of the housing 62 is not provided for receiving BD and DVD, but a tray. Alternatively, the slots 62c and 62e for inserting BD and DVD may be opened, and the shutters 62d and 62f may be provided in the slots 62c and 62e. In this case, it is necessary to provide a guide / leading mechanism for BD and DVD inside the slots 62c and 62e. With the configuration related to the slots 62c and 62e described above, the tray and the tray drive mechanism can be omitted, and the apparatus can be easily downsized.

  Further, as shown in another recording apparatus 70 in FIGS. 11A and 11B, openings 72b and 72c are formed on the upper surface 72a of the housing 72 instead of the tray, and the openings 72b and 72c are formed. Opening and closing type lid parts 73 and 74 are provided to be closed, and the optical pickup parts 77a and 78a and motor parts 77b and 78b are provided in the recesses 72d and 72e in the openings 72b and 72c in which the lid parts 73 and 73 are opened. An arranged configuration may be used. Note that the recording device 70 of the modified example is for the BD on the right side and for the DVD on the left side, and the lids 73 and 74 are opened by pressing the eject buttons 75 and 76 near the openings 72b and 73c. Yes. In the recording apparatus 70 of this modified example, it is not necessary to provide a mechanism for receiving BD and DVD inside the casing 72, and the components related to BD and DVD can be centrally arranged on the upper portion. It is preferable in that the space can be used efficiently.

  Further, FIGS. 12A and 12B show a recording apparatus 80 according to another modification. The recording apparatus 80 is characterized in that a vertical rectangular parallelepiped casing 82 having a height dimension larger than that in the horizontal direction is used, and receiving portions for BD and DVD are arranged in the vertical direction. Specifically, openings 82c and 82e provided with openable and closable shutters 82d and 82f are formed at the upper and lower portions of the front surface 82a of the housing 82, and a display unit 83 is disposed in the middle part, and the side of each opening 82a and 82e. Eject buttons 84 and 85 are provided. When the eject buttons 84 and 85 are pressed, the first tray 86 for BD and the second tray 87 for DVD are pulled out from the openings 82c and 82e. Since the recording device 80 having such a configuration has a smaller size in the horizontal direction (horizontal direction) than the other recording storage units 1, 60, 70, it is suitable when the installation space is limited. In the vertical recording apparatus 80, a configuration in which slots for inserting a BD and a DVD shown in FIG. 10 are provided instead of the trays 86 and 87 can be applied.

  Further, in the above-described embodiment and each modification, the example in which the BD is used as the first recording medium has been described. However, an HDDVD can be used instead of the BD. In this case, it is necessary to change the configuration of the BD drive unit 28 to a configuration that matches the data processing for the HDDVD.

  Furthermore, in the above-described embodiments and modifications, the second recording medium can also be a removable recording medium other than DVD, such as various magnetic tapes, optical disks other than DVD, semiconductor memory, and removable A type of hard disk drive or the like can be applied as the second recording medium. When the second recording medium is changed to the above-described removable recording medium other than the DVD as described above, the configuration of the DVD drive unit 29 can be replaced with a drive unit having a configuration that matches the data processing for the recording medium to be changed. is necessary.

  Of course, BD and HDDVD are also included in optical disks other than DVD that can be applied to the second recording medium. When BD is applied to the first recording medium and the second recording medium, respectively, two BDs are used. The recording capacity can be secured, which is more suitable for recording digital high-definition broadcasting. In addition, when BD or HDDVD is applied to the first recording medium and HDDVD or BD is applied to the second recording medium, data processing can be performed on two types of recording media having large recording capacities with different recording methods. It is possible to secure an apparatus configuration that can freely use data recorded on each recording medium without being restricted by a recording method.

  Furthermore, in the above-described embodiments and modifications, the third recording medium is not limited to the hard disk device 17, and other types of recording media can be applied to the third recording medium. As the recording medium applicable as the third recording medium, various types of removable recording media applicable as the first recording medium and the second recording medium can be used in addition to the type attached in the apparatus, and the hard disk device 17 can be used. When a removable recording medium is applied instead, the hard disk device 17 and the connection interface unit 30 are replaced with a drive unit that matches the recording medium to be applied.

  In the above-described embodiments and modifications, the configuration using three recording media has been described. However, a data processing unit that can handle three or more recording media, such as a fourth recording medium and a fifth recording medium, is further provided. Is also possible. As the types of recording media that can be handled by the newly provided data processing unit, the types that can be applied as the first recording medium, the second recording medium, and the third recording medium described above can be used. It is necessary to provide a drive unit corresponding to the type of recording medium inside the apparatus as a data processing unit. By making it possible to support three or more recording media in this way, it is possible to realize further multi-directional dubbing processing and further improve the usability of data held by the user.

  As described above, when a recording medium other than a DVD is used as the second recording medium, the data processing for the second recording medium can be read-only. In such a case, the second recording medium The dubbing process with dubbing destination is omitted. Also, when a recording medium other than the hard disk device 17 is used as the third recording medium, the data processing for the third recording medium can be read-only, and in this case, the dubbing process with the third recording medium as the dubbing destination is omitted. In this way, the data processing for the second recording medium and the third recording medium is made read-only, so that the apparatus configuration can be simplified and the apparatus cost can be reduced. In addition, when data transmission / reception with an external device is unnecessary, the IEEE 1394 terminal unit 9 can be omitted, and in this case, the device configuration can be further simplified.
