Description

  The present invention relates to a composite recording apparatus, and in particular, a video cassette recorder is applied to a device or the like.

  A large number of composite recording devices that combine a plurality of electronic devices, such as a composite device of a DVD recording device and a video cassette recording device (hereinafter referred to as a VCR recording device), have appeared on the market. A typical example of such a composite recording apparatus is a composite of a DVD recording device and a VCR recording device, which enables bidirectional recording.

  When trying to create a copy using such a composite recording device, it is necessary not to make a copy of a copy-prohibited device such as commercially available software.

  In the case of DVD software, it is immediately determined whether the copy is prohibited by the TOC portion to be read first, and it is possible to control not to perform the copy operation, but in the case of the video cassette, the tape is not run to some extent. Whether or not a copy prohibition signal is included cannot be determined. Moreover, in the case of a tape, since there is a non-recorded portion at the beginning, it takes time to determine.

For this reason, in the case of dubbing from a conventional VCR recording device to a DVD recording device, the dubbing operation is started first, and the recording is stopped when the copy signal is detected, or the information on the full screen black is recorded at that time. I am doing so.

  According to the composite recording apparatus of the present invention, when dubbing from a video cassette to another recording medium, the video cassette is first run to determine whether copying is possible, and when copying is possible, dubbing is performed. Therefore, the dubbing destination medium is not wasted.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing an outline of the configuration and functions related to the dubbing operation of the composite recording apparatus according to the present invention.

  The operation unit 1 represents, for example, a key provided on a panel surface of a DVD recording apparatus and a receiving unit of a remote controller. The most frequently used is a remote controller using an infrared signal, and the operation unit 1 receives a key input from a key provided on the front panel surface of the apparatus or receives a remote control signal, and a key detection unit in the control unit 10 11 The control unit 10 surrounded by a broken line in FIG. 1 is realized as a microcomputer function.

  The key detection unit 11 translates or interprets the signal received from the operation unit 1 to detect which operation signal it is and sends it to the user operation management unit 12.

  The user operation management unit 12 calls a necessary operation processing unit in accordance with the received operation signal.

Here, a dubbing start instruction / dubbing end instruction is given to the dubbing operation processing unit 20 that manages and processes the dubbing operation. The dubbing operation processing unit 20 described below represents the function or program content performed in the control unit 10 as a block.

  The dubbing operation processing unit 20 controls the drive and signal input / output of the video cassette 32 via the VCR unit 31, and the DVD control unit controls the drive and signal input / output of the DVD 38 via the DVD drive 37. 14 and an OSD (On Screen Display) 15 that displays various message information on the monitor 41 via the video output circuit 39 is controlled.

Hereinafter, the operation of the composite recording apparatus according to the present invention will be described in detail, taking as an example the case of dubbing from a video cassette to a DVD.

  The VCR unit 31 is a recording / reproducing type here, but since the present invention relates to dubbing from a video cassette to another medium, it may be a reproduction-only type.

  Based on a signal from the VCR unit 31, the VCR control unit 13 detects whether or not the video cassette 32 is inserted, the presence of a recording prohibition control claw, and controls the video cassette recording and playback, and driving such as running and stopping.

  On the other hand, the DVD control unit 14 obtains information such as the presence / absence of a DVD disk, the type of DVD, the possibility of recording (presence / absence of finalization), the remaining amount, etc. from the signal from the DVD drive 37, and the recording / playback, rotation, and stop. Control the drive.

  The media discriminating unit 21 receives signals from the VCR control unit 13 and the DVD control unit 14 to determine whether the media set at the dubbing source and the dubbing destination are suitable for dubbing, and can be dubbed. Is set, a “media OK” signal is sent to the copy information determination unit 22.

  The copy information discriminating unit 22 first instructs the VCR control unit 13 to drive the tape in order to determine whether or not the copy prohibition signal is included in the dubbing source video cassette 32, and the VCR unit. The video signal read at 31 is processed by the VCR playback video signal processing unit 33. At this time, the recorded part is reproduced after the non-recorded part. If the video signal (reproduced signal) includes a copy management signal such as Macrovision (R) (Macrovision) or CGMS, these are The extracted copy management signal is sent to the execution control unit 24 together with the copy information determination unit 22. The copy management signal is usually superimposed on the vertical synchronization signal blanking interval (VBI) of the video signal.

  When the copy information determination unit 22 determines that the copy management signal can be copied, this “copy OK” signal is sent to the unit preparation unit 23.

  The unit preparation unit 23 instructs the VCR control unit 13 and the DVD control unit 14 to prepare for dubbing. This preparation includes stopping and rewinding the video cassette described later. When the preparation in the unit preparation unit 23 is completed, a completion signal is sent to the execution control unit 24.

  The execution control unit 24 instructs the VCR control unit 13 and the DVD control unit 14 to start dubbing, and performs control during execution of the dubbing. That is, the VCR control unit 13 instructs the VCR unit 31 to perform a reproduction operation, and the DVD control unit 14 instructs the DVD drive 37 to perform a recording operation, and controls display of a guide on the OSD.

The dubbing control unit in claims 1 and 3 corresponds to the unit preparation unit 23, the execution control unit 24, and the end control unit 25 in the dubbing operation processing unit.
The video signal V and the audio signal A output from the VCR unit 31 when the execution of dubbing is instructed are processed by the VCR playback video signal processing unit 33 and the VCR playback audio signal processing unit 34, respectively, and then recorded on the DVD recording video. The signal processing unit 35 and the DVD recording audio signal processing unit 36 supply the DVD drive 37 as a bit stream signal for recording.

  During this recording operation, output signals from the VCR playback video signal processing unit 33 and the VCR playback audio signal processing unit 34 are displayed on the monitor 41 via the video signal output processing unit 39 and the audio signal output processing unit 40, respectively. In addition, various messages output from the dubbing operation processing unit, for example, messages such as “Media not set” and “Copy prohibited” are processed by the OSD processing unit 15 into video signals for display, and video signal processing is performed. It is displayed on the monitor 41 via the unit 39.

  When the recording on the DVD disc is completed, or when the tape of the video cassette is stopped due to a normal or abnormal cause, when the dubbing end signal is given from the execution control unit 24 to the end control unit 25, the end control unit 25 Sends an end signal to the VCR control unit 13 and the DVD control unit 14, and the VCR unit 31 and the DVD drive 37 are stopped. Further, when the copy management information is determined to be a copy prohibition signal by the copy information determination unit 22 and when the media determination unit 21 determines that the medium is not suitable for dubbing, the end control unit 25 receives these prohibition signals. Then, an end signal is sent from the end control unit 25 to the VCR control unit 13 and the DVD control unit 14, and the VCR unit 31 and the DVD drive 37 are stopped.

  FIG. 2 is a flowchart showing the procedure of dubbing control in the composite recording apparatus described above.

  Here, it is assumed that the dubbing source video cassette 31 and the dubbing destination DVD medium are set.

  First, when the dubbing key is pressed and a dubbing from the VCR to the DVD is instructed (step S101), the medium is determined (step S102).

  When the media is normal at both the dubbing source and the dubbing destination, the video cassette is played back (step S103). After reaching the recording portion, the reproduction signal is sent to the copy information determination unit 22 as copy management information by the VCR reproduction video signal processing unit 33, and it is determined whether or not a copy prohibition signal such as macrovision (R) is included. (Step S104).

  If copying is not prohibited, the unit preparation unit 23 instructs the VCR control unit 13 to temporarily stop running the video cassette (step S105), and the DVD control unit 14 prepares for DVD recording. An instruction is given (step S107).

  When the above preparation is completed, the execution control unit 24 gives an instruction to start dubbing to the VCR control unit 13 and the DVD control unit 14, and dubbing is started (step S109).

  On the other hand, when the copy prohibition signal is detected by the copy information determination unit 22 (NG in step S104), the OSD processing unit 15 displays a warning display indicating illegal copying on the monitor 41 (step S111). The running of the VCR is stopped (step S113), and the dubbing operation is ended (step S115).

  If the medium is not recordable in step S102, a warning display indicating that the medium is not ready is displayed (step S121), and the operation is terminated (step S115).

  FIG. 3 is a flowchart showing the procedure of another embodiment of the dubbing control in the composite recording apparatus. This flowchart is similar to FIG. 2, and the same steps are assigned the same step numbers.

  The difference from FIG. 2 is that, when copying is not prohibited in step S104, the playback of the video cassette is rewound (step S106) after the running of the video cassette is paused (step S105). Also, when a copy prohibition signal is detected (step S104), the video cassette is rewound by the amount of playback after the warning display (step S111) (step S112).

  Such rewinding is to return to the dubbing start position, and usually within 5 seconds, preferably about 2 seconds is sufficient, but it may be possible to rewind to the start end of the tape.

  In the embodiment shown in FIG. 2, dubbing is performed from the position where the traveling has progressed in order to detect the copy prohibition signal, and it is inevitable that a part of the recording signal is missing. Does not occur.

  If the video cassette is copy-prohibited, the dubbing operation is not performed, so it is not always necessary to perform rewinding for playback.

  In the above embodiment, dubbing from a video cassette to a DVD is assumed. However, if the dubbing destination is a digital recording device in a composite recording apparatus, the present invention can be applied regardless of the media. That is, the present invention can be applied to an optical disk such as a CD-R, a CD-R / W, a DVD ± R, a DVD ± R / W, and a Blu-ray DVD, a magnetic disk such as a hard disk, and a medium using various media such as a memory module.

It is a block diagram which shows the structure of one Example of the composite video recording apparatus concerning this invention. It is a flowchart which shows an example of the control of dubbing in FIG. 6 is a flowchart illustrating another example of dubbing control in FIG. 1.
