Description

  The present invention relates to a recording apparatus for recording / reproducing video / audio data, an optical disk apparatus for recording / reproducing video / audio data to / from an optical disk, and a magnetic tape apparatus for performing recording / reproduction processing on a magnetic tape. The present invention relates to a recording / reproducing apparatus and a method for controlling the recording / reproducing apparatus.

  Recently, with the spread of digital devices, broadcast receiving apparatuses such as hard disk (HDD) / DVD (Digital Versatile Disc) recorders are becoming common. However, for users who have used a VTR (Video Tape Recorder), a recording / reproducing apparatus combining an HDD / DVD recorder and a VTR has been put on the market.

  By the way, when the video / audio data is copied between the HDD and the DVD, if the re-encoding process is not required for the video / audio data, the video / audio data may be copied as it is. In this case, the DVD recording / reproducing speed can be maximized (the rotation speed of the DVD medium is maximized). However, when the DVD recording / reproducing speed is maximized, vibration occurs.

  It is known that when recording or reproduction processing is performed in a VTR, a signal to be recorded / reproduced deteriorates if the VTR vibrates. In the HDD / DVD / VTR composite apparatus described above, if the vibration of the DVD is large, the vibration is transmitted to the VTR and the recording / reproducing signal may deteriorate, and the recording / reproducing performance of the VTR may deteriorate.

In Patent Document 1, when recording processing to a disk medium is started, it is determined whether the shooting state at that time is ON or OFF, and a recording mode with less noise and vibration generated by the recording / playback unit is set during shooting. The technology to do is described.

  An embodiment of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram showing a schematic configuration of an HDD / DVD / VTR integrated recording / playback system according to an embodiment of the present invention.

  As shown in FIG. 1, the HDD / DVD / VTR integrated recording / playback system 100 of this embodiment plays back video / audio data recorded on a magnetic tape (magnetic tape) T and records video / audio input data. A tape drive unit (magnetic tape device) 11; a digital recording / reproducing unit 20 that compresses and encodes video / audio input data and records it on a recording medium D or HDD such as a DVD-RAM; and a VTR unit 10 and a digital recording / reproducing unit A control unit 101 that controls the system 20, a user interface unit 102, and a tuner 110.

  The tuner receives a broadcast signal and outputs a video / audio signal obtained by demodulating the received broadcast signal to the VTR unit 10 and the digital recording / playback unit 20.

  The VTR unit 10 includes a VTR control unit 12 and a tape drive unit 11. In the VTR unit 10, the tape drive unit records the video / audio signal supplied from the tuner 110 on the magnetic tape T, and reproduces the recorded signal to generate video / audio data. The VTR control unit 12 controls the entire VTR unit 10 while exchanging control signals via the system control unit 101, the control unit 27 of the digital recording / playback unit 20, and the control signal line. The VTR control unit 12 includes a reserved recording setting storage unit 12b that stores a reserved recording setting registered by the user, and a VTR reserved recording time search unit 12a that searches for a setting stored in the reserved recording setting storage unit 12b.

  The digital recording / playback unit 20 includes an A / D conversion unit 21 that converts analog video / audio data supplied from the tuner 110 into a digital signal, a digital processing unit 22, an HDD drive unit (recording device) 23, and a disk drive unit. (Optical disk device) 24, D / A converter 25, selector 26, and HDD / DVD controller 27.

  In the digital recording / playback unit 20, the HDD / DVD control unit 27 controls the entire digital recording / playback unit 20 while exchanging control signals via the system control unit 101, the VTR control unit 12, and control signal lines. The HDD / DVD control unit 27 also supports a DVD type D, a disc type discriminating unit 27a that discriminates the type of DVD media D in the disc drive unit 24 (DVD-RAM, DVD-RW, DVD-R, DVD + R, etc.) Dubbing is completed when the dubbing process from the HDD drive unit 23 to the disk drive unit 24 or the dubbing process from the disk drive unit 24 to the HDD drive unit 23 is completed. A dubbing end time prediction unit 27c for predicting the time to be performed.

  The A / D converter 21 receives the analog video / audio signal output from the tuner 110 and digitally converts it. The encoder unit 22 b of the digital processing unit 22 compresses and encodes the video / audio data converted by the A / D conversion unit 21. The compression-coded video / audio data is supplied to the HDD drive unit 23 or the disk drive unit 24 through the data processing unit 22a.

  Then, the video / audio data after compression encoding received from the HDD drive unit 23 or the disk drive unit 24 is recorded on a recording medium D such as a DVD-RAM. The video / audio data recorded on the recording medium D is compressed and decoded by the decoder unit 22c via the data processing unit 22a of the digital processing unit 22, and is passed from the D / A conversion unit 25 to the selector 26. The selector 26 selects one of the video / audio data from the tape drive unit 11 and the video / audio data compressed and decoded by the decoder unit 22c and outputs the selected data to an AV television or the like.

  When the recording / playback system 100 is operated to shift to an initial setting mode for setting initial settings, the control unit outputs a setting screen shown in FIG.

  When “DVD dubbing speed” is selected on the setting screen shown in FIG. 2, either “high speed” or “low speed (silent)” can be selected.

  When “High speed” is selected, the low speed (silent) mode ON / OFF setting is set to OFF, and the dubbing between HDD / DVD is performed at the maximum recording speed (maximum playback speed) that the DVD media and the HDD drive unit 23 support. Perform dubbing. When “low speed (silent)” is selected, the low speed (silent) mode ON / OFF setting is set to ON, and dubbing is performed at a reduced double speed when dubbing between HDD / DVD. When the low-speed (silent) mode ON / OFF setting is ON, dubbing is performed by limiting the rotation speed of the DVD medium regardless of the maximum recording speed (maximum reproduction speed) supported by the DVD medium and the HDD drive unit 23.

  When VTR recording / playback and HDD / DVD high-speed dubbing are performed simultaneously, even if the low-speed (silent) mode ON / OFF setting is turned off, the low-speed (silent) mode ON / OFF setting is automatically set when certain conditions are met. Is turned on, the double speed of HDD and DVD is lowered, and HDD and DVD are dubbed.

(Dubbing between HDD / DVD)
Next, when simultaneously performing high-speed dubbing of HDD and DVD during VTR recording or playback, the type of DVD recording medium (DVD-RAM, DVD-RW, DVD-R, DVD + R, etc.) is identified and limited When using DVD media (DVD-R), the operation is shown in the flowchart of FIG.

  In the following description, the term dubbing between HDDs / DVDs is used, but the process of copying the video / audio data stored in the HDD drive unit 23 to the DVD medium D in the disk drive unit 24, and the disk drive unit 24 The process of copying the video / audio data stored in the DVD medium D to the HDD drive unit 23 is shown.

  When the user instructs high-speed dubbing processing between the HDD and the DVD using a remote controller or the like during VTR recording or playback, the user interface unit 102 accepts a high-speed dubbing processing command. The user interface unit 102 notifies the system control unit that a dubbing processing command has been issued.

  The system control unit 101 instructs the HDD / DVD control unit 27 to perform dubbing processing. The HDD / DVD control unit 27 determines whether or not the low-speed (silent) mode ON / OFF setting is ON (step S11). When the low speed (silent) mode ON / OFF setting is on (No in step S11), the HDD / DVD control unit 27 determines whether the tape drive unit 11 is performing a recording process or a reproduction process (step S12). ).

  When it is determined that the recording process or the reproduction process is not performed in the tape drive unit 11 (No in step S12), the HDD / DVD control unit 27 inquires of the VTR control unit 12 whether there is a reserved recording program. In response to an inquiry from the HDD / DVD control unit 27, the VTR reserved recording time search unit 12a searches the contents stored in the reserved recording setting storage unit 12b and informs the HDD / DVD control unit 27 whether there is a reserved recording program. Answer. The HDD / DVD control unit 27 determines whether or not there is a scheduled recording program according to the answer result from the scheduled recording setting storage unit 12b (step S17).

  When it is determined that there is a reserved recording program (Yes in step S17), the HDD / DVD control unit 27 inquires the VTR control unit 12 about the recording start time of the latest reserved recording program. In response to the inquiry from the HDD / DVD control unit 27, the VTR reserved recording time search unit 12a detects the recording start time of the most recent reserved recording program and responds to the HDD / DVD control unit 27 (step S18). The dubbing end time prediction unit 27c predicts the dubbing end time from the video / audio data amount and the transfer rate (step S19).

  The HDD / DVD control unit 27 compares the recording start time detected by the process of step S19 with the dubbing end time predicted by the process of step S19, and determines whether or not the reserved recording and the dubbing are simultaneously performed. (Step S20).

  When it is determined that the tape drive unit is performing the recording process or the reproduction process by the process at step S12 (Yes at step S12), or when it is determined that the reserved recording and the dubbing are simultaneously performed in the process at step S20 (step In S20 (Yes), the disc type discriminating unit discriminates the type of the DVD medium D inserted in the disc drive (step S13). The type of DVD medium to be discriminated here is a type according to the structure of the optical disc, and is a type of so-called DVD-RAM, DVD-RW, DVD-R, DVD + R or the like.

  The HDD / DVD control unit 27 determines whether or not the type determined by the disk type determination unit 27a is DVD-R (step S14).

  If it is determined in step S14 that the DVD-R is not used (No in step S14), if it is determined in step S17 that there is no reserved recording program (No in step S17), or a reservation is made in step S20. When it is determined that the recording and the dubbing do not operate simultaneously (No in step S20), the HDD / DVD control unit 27 displays the “high-speed mode operation” on the screen (step S15), and HDD / DVD high-speed dubbing processing Is started (step S16).

  If it is determined in step S11 that the low speed (silent) mode ON / OFF setting is not ON (No in step S11), if it is determined in step S14 that it is a DVD-R (Yes in step S14), Alternatively, the HDD / DVD controller 27 sets the low speed (silent) mode regardless of the low speed (silent) mode ON / OFF setting (step S21). The HDD / DVD control unit 27 displays the “low speed mode operation” on the screen (step S22) and starts the HDD / DVD low speed dubbing process (step S23).

  With the above processing, when dubbing between HDDs / DVDs is performed, if the dubbing and recording processing or playback processing by the tape drive unit 11 may be performed at the same time, the type of the DVD medium is determined, and the determined type When DVD is a DVD-R, regardless of the low-speed (silent) mode ON / OFF setting, the low-speed (silent) mode is set to limit the rotation speed of the DVD medium D, and the vibration of the disk drive unit 24 is affected by the tape. Transmission to the drive unit 11 can be suppressed. As a result, the signal recorded / reproduced by the tape drive unit 11 does not deteriorate, and the recording / reproduction performance of the VTR does not deteriorate.

  The vibration of the disk drive unit is transmitted to the tape drive unit when the DVD medium D supports high-speed, but the DVD-R is generally used as the high-speed compatible medium. Accordingly, when the DVD medium D built in the disk drive unit 24 is other than DVD-R, the vibration is not transmitted to the tape drive unit 11. Therefore, in the case of DVD-R, the low speed (silent) mode is set. Dubbing should be done.

  If a DVD medium compatible with high speed appears and the disk drive unit 24 supports DVD media, the type of the DVD medium that has appeared can be set to low speed regardless of the low speed (silent) mode ON / OFF setting. (Silent) mode may be set.

(Recording / playback processing of magnetic tape)
Next, a procedure of processing when the user instructs recording processing (reproduction processing) of the magnetic tape T will be described with reference to FIG.

  When a user instructs recording or playback processing of a VTR using a remote controller or the like, the user interface unit 102 receives a playback command (or recording command). The user interface unit 102 notifies the system control unit 101 that there has been a reproduction command (or a recording command).

  The system control unit 101 notifies the VTR control unit 12 and the HDD / DVD control unit 27 that a reproduction command (or recording command) has been issued. The HDD / DVD control unit 27 determines whether or not the HDD / DVD dubbing process is performed in the digital recording / playback unit 20 (step S31).

  When the dubbing process is being performed, the HDD / DVD control unit 27 determines whether or not the low speed (silent) mode ON / OFF setting is OFF (step S32).

  When the low speed (silent) mode ON / OFF setting is OFF (No in step S32), the HDD / DVD control unit 27 determines the type of the DVD medium D inserted in the disk drive unit 24 (step). S33). The HDD / DVD control unit 27 determines whether or not the determined type of the DVD medium D is DVD-R (step S34).

  When the discriminated type of the DVD disk D is DVD-R (Yes in step S34), the HDD / DVD control unit 27 switches the dubbing process to the low speed (silent) mode (step S35) and displays “low speed mode operation” on the screen. "Is displayed on the OSD (Over Screen Display) (step S36).

  If it is determined in step S31 that the HDD / DVD dubbing process is not being performed, or if it is determined in step S32 that dubbing is being performed in the low speed (silent) mode (Yes in step S32), the optical disk is determined in step S34. If the type is not DVD-R (No in step S34), or after performing the processing in step S36, the HDD / DVD control unit 27 enables the tape drive unit operation permission signal, and the tape drive unit 11 is permitted (step S37). When the permission signal is enabled, the VTR control unit 12 drives the tape drive unit 11 to perform reproduction processing (or recording processing) of the magnetic tape T.

  With the above processing, when the user instructs the recording process or the reproduction process by the tape drive unit 11, the dubbing between the HDD / DVD and the recording process (reproduction process) may be performed at the same time. When the discriminated type is DVD-R, the rotational speed of the DVD medium D is limited by setting the low-speed (silent) mode regardless of the low-speed (silent) mode ON / OFF setting, It is possible to suppress the vibration of the disk drive unit 24 from being transmitted to the tape drive unit 11. As a result, the signal recorded / reproduced by the tape drive unit 11 does not deteriorate, and the recording / reproduction performance of the VTR does not deteriorate.

(Corresponding recording speed (playback speed) discrimination)
In the following description, when high-speed dubbing is performed between the HDD drive unit 23 and the disk drive unit 24 during recording or reproduction of the magnetic tape T, the DVD medium is a high-speed disc (× 2, × 4, × 8 times, etc.). In the case where a disc corresponding to a specific double speed is used, an example in which dubbing is performed by reducing the double speed of the HDD and DVD will be described. In the present embodiment, the procedure of an example of the case where the recording speed is “8 × or higher” will be described with reference to the flowchart of FIG.

  When the user instructs a dubbing process between the HDD and the DVD using the remote controller or the like during recording or reproduction of the magnetic tape T by the tape drive unit 11, the user interface unit 102 receives a dubbing process command from the user. The user interface unit 102 notifies the system control unit 101 that a dubbing processing command has been issued.

  The system control unit 101 determines whether or not the low-speed (silent) mode ON / OFF setting is ON (step S41). When the low-speed (silent) mode ON / OFF setting is ON (No in step S41), the system control unit 101 determines whether the recording process or the reproduction process is being performed in the tape drive unit 11 (step S42). .

  When it is determined that the recording process or the reproduction process is not performed in the tape drive unit 11 (No in step S12), the HDD / DVD control unit 27 inquires of the VTR control unit 12 whether there is a reserved recording program. In response to an inquiry from the HDD / DVD control unit 27, the VTR reserved recording time search unit 12a searches the contents stored in the reserved recording setting storage unit 12b and informs the HDD / DVD control unit 27 whether there is a reserved recording program. Answer. The HDD / DVD control unit 27 determines whether or not there is a scheduled recording program according to the answer result from the scheduled recording setting storage unit 12b (step S47).

  When it is determined that there is a reserved recording program (Yes in step S47), the HDD / DVD control unit 27 inquires of the VTR control unit 12 about the recording start time of the latest reserved recording program. In response to the inquiry from the HDD / DVD control unit 27, the VTR reserved recording time search unit 12a detects the recording start time of the latest reserved recording program, and replies to the HDD / DVD control unit 27 (step S48). The dubbing end time predicting unit 27c predicts the dubbing ending time from the data amount and transfer rate of the video / audio data to be dubbed (step S49).

  The HDD / DVD control unit compares the recording start time detected by the process of step S49 with the dubbing end time predicted by the process of step S49, and determines whether or not the scheduled recording and the dubbing are simultaneously performed. (Step S50).

  When it is determined in the process of step S42 that the tape drive unit is performing the recording process or the playback process (Yes in step S42), or in the process of step S50, it is determined that the reserved recording and the dubbing are simultaneously performed (step S42). The maximum corresponding double speed discriminating unit 27b detects the recording / reproducing speed of the DVD medium D inserted in the disc drive unit 24 (step S43).

  The HDD / DVD control unit 27 determines whether or not the DVD medium D is compatible with a recording / reproducing speed of 8 × speed or more from the detection result of the maximum corresponding double speed determination unit 27b (step S44).

  When it is determined in the process of step S44 that the recording / playback speed of 8 × speed or higher is not supported (No in step S44), or in the process of step S47, it is determined that there is no reserved recording program (No in step S47). Alternatively, when it is determined in the process of step S50 that the scheduled recording and the dubbing do not operate simultaneously (No in step S50), the HDD / DVD control unit 27 OSD displays “high speed mode operation” on the screen (step S45). ), HDD / DVD high-speed dubbing processing is started (step S46).

  If it is determined in step S41 that the low speed (silent) mode ON / OFF setting is not ON (No in step S41), or it is determined in step S44 that the recording / reproducing speed is 8 × or higher. If so (Yes in step S44), the HDD / DVD control unit sets the low speed (silent) mode (step S51).

  The HDD / DVD control unit displays “low speed mode operation” on the screen (step S52) and starts HDD / DVD low speed dubbing processing (step S53).

  With the above processing, when dubbing between HDD / DVD is performed, the recording (playback) speed corresponding to the DVD medium is determined when the dubbing and the recording process or the playback process by the tape drive unit 11 may be performed at the same time. However, when the corresponding recording (playback) speed is 8 times or higher, the rotational speed of the DVD media D is limited by setting the low speed (silent) mode regardless of the low speed (silent) mode ON / OFF setting. Thus, the vibration of the disk drive unit 24 can be prevented from being transmitted to the tape drive unit 11. As a result, the signal recorded / reproduced by the tape drive unit 11 does not deteriorate, and the recording / reproduction performance of the VTR does not deteriorate.

  In the above embodiment, the type of the DVD medium D is determined and the low speed (silent) mode is set according to the type. However, the low speed (silent) mode is set regardless of the type of the DVD medium D. Also good.

  If the DVD media D is compatible with 8 × speed or higher, the processing of step S51 is performed at low speed by performing the processing of steps S44 and 45 instead of the processing of steps S33 and 34 described with reference to the flowchart of FIG. (Silent) mode may be set.

  In the above example, in the case of a DVD medium that supports 8 × speed or higher, the low speed (silent) mode is set regardless of the low speed (silent) mode ON / OFF setting. However, the vibration of the disk drive unit 24 is affected by the tape drive. If it is not transmitted to the part, you may set a higher speed. Conversely, if the vibration of the disk drive unit 24 is transmitted to the tape drive unit, a higher speed may be set. That is, the set speed may be selected in accordance with the degree to which the vibration of the disk drive unit 24 is transmitted to the tape drive unit.

  In the above embodiment, an example of a DVD as an optical disk has been described. However, an HD DVD (High Definition Digital Versatile Disc) standard or Blu-ray standard optical disk may be used.

  In addition, since the vibration in the disk drive unit is transmitted to the tape drive unit, the reproduction of the video / audio data recorded on the DVD medium and the recording process or reproduction process of the tape drive unit are performed simultaneously. You may make it set to low speed (silent) mode. Further, it may be set regardless of the type of DVD media, or may be set according to the type of DVD media.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment.
