The present invention relates to a composite video device in which a first video device such as a video cassette recorder (VCR) and a second video device such as a disc recorder or a disc player are integrally formed. A dubbing recording control apparatus and method are disclosed.

Recently, a first video device such as a VCR capable of reproducing or recording and storing video and audio signals recorded on a videotape, a recordable DVD (eg, DVD-R, DVD-RW), A second video device such as a disc recorder capable of recording, storing, or reading and reproducing MPEG-type video and audio data on the same optical disc has been developed and commercialized by introducing a composite video device in which one is integrated.

As shown in FIG. 1, the tape deck 10, the VCR system 11, the first microcomputer 12, and the OSD generation unit 13 are provided in a VCR part of the composite video device. The disc recorder part includes an optical disc 20, an optical pickup 21, a second microcomputer 22, a VDR (Video Disc Recorder) system 23, and an external connection device such as a television. The output part 24 which is connected and may be integrated.

The first microcomputer 12 receives a user's key input. For example, the user requests a dubbing operation of simultaneously recording and operating a V-Cal while playing a disc recorder. In this case, the first microcomputer 12 operates the VCR system 11 and controls the VDR system 23 through an interface with the second microcomputer 22 to control the optical disc 20. The A / V data stream read out and reproduced from the C1) is converted into an A / V signal, signal processed, and recorded on the video tape. This will be described in detail below.

FIG. 2 is a flowchart illustrating a method of controlling dubbing recording in a general composite video apparatus. For example, when a user requests to dub the A / V data stream recorded on an optical disc onto a video tape, In the first microcomputer 12, a dubbing recording mode (Disc to Tape) corresponding thereto is set (S10).

The first microcomputer 12 controls the VDR system 23 through an interface with the second microcomputer 22 to perform a reproduction operation of the optical disc, and the VCR system 11. ), The recording operation of the video tape is performed (S11).

In other words, the VDR system 23 reads and reproduces the A / V data stream recorded on the optical disc, and the VCR system 11 receives the A / V data stream and converts it into an analog A / V signal. After the conversion and signal processing, a series of dubbing operations to write to the videotape is performed.

On the other hand, during the above dubbing operation, for example, the user stops the optical disc (eg DVD) playback operation (S12), or the A / V signal is pulled to the entire video tape. If it is recorded (S13) or if the user inputs a dubbing stop key (Stop) (S14), the first microcomputer 12 stops the recording operation of the VCR system 11 and at the same time, the first key. 2 The reproduction operation of the VDR system 23 is stopped through the interface with the microcomputer 22, so that the dubbing operation is stopped (S17).

On the other hand, when the user inputs a pause key (Pause Key) (S15), after temporarily stopping the dubbing operation (S16), more than a predetermined time has elapsed, or the pause is released by the user. If so, the dubbing operation is resumed from that point.

However, in general composite video equipment, the dubbing operation is continuously or automatically stopped depending on a key input or a full recording state of a videotape selected by a user, and whether or not the optical disc is basically played or stopped. For example, while the reproduction mode of the optical disc is maintained even while the defect area of the optical disc is repeatedly played, there is a problem in that a dubbing operation is continued to generate a noise recording section on the video tape. .

Further, when performing a Title Playback mode for reading out and reproducing the A / V data stream of the Title recorded on the optical disc, and switching to the Menu Mode at the request of the user, Since the second microcomputer 22 continuously recognizes the current operation mode as a play mode, the dubbing operation is continuously performed, which causes a problem that a menu image is unnecessarily recorded on the video tape.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and includes an optical disc in a composite video device in which a first video device such as a VCR and a second video device such as a disc recorder or a disc player are integrally formed. During the dubbing recording operation of reading and playing back the A / V data stream recorded on the video tape and recording it as an A / V signal on the video tape, playback time information such as a presentation time stamp (PTS) read from the optical disc is read. Dubbing recording control apparatus in a composite video apparatus for discontinuity or to automatically stop the recording operation for recording A / V signals on the videotape when switching from the title playback mode of the optical disc to the menu mode. And to provide a method, which has a purpose.

In order to achieve the above object, a dubbing recording control method in a composite video apparatus according to the present invention includes A / V data stream read / reproduced from an optical disc when a dubbing recording operation is performed in the composite video apparatus, Recording in a V signal; And stopping the recording of the A / V signal on the videotape when the reproduction time information read out from the optical disc has a discontinuity or is switched from the title reproduction mode to the menu mode. ,

In addition, the dubbing recording control apparatus in the composite image device according to the present invention, when performing a dubbing recording operation, the first image device for recording the A / V signal to the video tape and through the interface with the first image device And information detecting means for detecting reproduction time information of the A / V data stream read from the optical disc, comprising a second video device for reading out and reproducing the A / V data stream recorded on the optical disc; Mode detection means for detecting a reproduction standby mode among the operation modes of the second video device; And control means for stopping the recording operation of the videotape through the interface with the first video device when the playback time information has a discontinuity or the second video device is in a playback standby mode. It is characterized by.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, preferred embodiments of a dubbing recording control apparatus and method in a composite imaging apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

Fig. 3 shows a configuration of a composite video device to which the present invention is applied, which includes a VCR as a first video device and a disc recorder (or disc player) as a second video device. The VCR part may include a tape deck 10, a VCR system 11, a first microcomputer 12, and an OS D generation unit 13. The disc recorder part includes an optical disc 20, an optical pickup 21, a second microcomputer 22, a VDR system 23, and an output unit 24 connected to an external connection device such as a television. It can be configured as.

The disc recorder part further includes a PTS detector 30 and a mode detector 31. The PTS detector and mode detector are included in the VDR system 23 or the second microcomputer 22. It may be included as hardware (Hardware) or software (Software), or may be installed as a separate configuration means respectively.

On the other hand, the PTS detection unit 30, as shown in Fig. 4, as playback time information for controlling the presentation of the A / V data stream read out from the optical disc 20, PES (Program Elementary) A Presentation Time Stamp (PTS) value recorded in a header of a packet is detected.

Then, it is detected whether the PTS value increases with continuity as the reproduction operation of the optical disc is performed. For example, as shown in FIG. 4, the PTS value is changed from the inner circumference to the outer circumference of the optical disc. If there is a defect area due to scratches or foreign substances during the reproducing operation, since the normal data cannot be read in the defect area, the PTS value is detected with discontinuity. In operation 30, a corresponding detection signal is output, and the second microcomputer 22 receiving the signal detects that the current defect area is being reproduced.

The second microcomputer 22 also pauses (VCR_Pauses) the recording operation of the VCR system 11 through the interface with the first microcomputer 12, thereby reproducing the defect area of the optical disc. The generated noise signal is prevented from being recorded on the video tape.

As shown in FIG. 5, the mode detection unit 31 performs a current operation when switching to a menu mode according to a user's request, etc. while performing a title playback mode. The mode is detected as a playback standby mode, and a corresponding detection signal is output, and the second microcomputer 22 receiving the mode recognizes that the current operation mode is a playback standby mode, not a normal playback mode. Done.

That is, as described above with reference to FIGS. 1 and 2, in the second microcomputer of the general composite video apparatus, even if the title playback mode is switched from the menu playback mode to the menu mode, the current operation mode is reproduced. In the second microcomputer to which the present invention is applied, the mode detection unit 31 recognizes that the current operation mode is the reproduction standby mode, not the normal reproduction mode.

Further, in the second microcomputer 22, the recording operation of the VCR system 11 is temporarily suspended (VCR_Pause) through the interface with the first microcomputer 12, while the menu image of the optical disc is displayed. This prevents the menu image from being continuously recorded on the videotape.

On the other hand, when the menu mode is released and the title reproduction mode is resumed, the mode detector 31 outputs a detection signal corresponding thereto, and the second microcomputer 22 receiving the menu mode receives the VDR system ( 23) to read and reproduce the A / V data stream of the optical disc, and to control the VCR system 11 via the interface with the first microcomputer 12 to record the video tape. Will be run again.

On the other hand, when the user selects any other operation mode other than the reproduction operation, the operation is performed while the reproduction operation is stopped, which will be described in detail below.

Fig. 6 shows an operation flowchart of a dubbing recording control method in the composite video device according to the present invention, for example, requesting a user to dub the A / V data stream recorded on an optical disc onto a video tape. In this case, the first microcomputer 12 sets a dubbing recording mode (Disc to Tape) corresponding thereto (S20).

In addition, the first micom 12 controls the VDR system 23 through an interface with the second micom 22 to perform a reproduction operation of an optical disc (eg, a DVD), Operation of the VCR system 11 is performed so that a recording operation of the video tape is performed (S21).

In other words, the VDR system 23 reads and reproduces the A / V data stream recorded on the optical disc, and the VCR system 11 receives the A / V data stream and converts it into an analog A / V signal. After the conversion and signal processing, a series of dubbing operations to write to the videotape is performed.

On the other hand, while performing the above dubbing operation, for example, the user stops the optical disc (eg DVD) playback operation (S22), or the A / V signal is recorded in the entire video tape as full. (S23) Or, if the user inputs a dubbing stop key (Stop Key) (S24), the first microcomputer 12 stops the recording operation of the VCR system 11 and at the same time, the second microcomputer The playback operation of the VDR system 23 is stopped through the interface with the operation 22 to stop the dubbing operation (S29).

On the other hand, as described above with reference to FIG. 4, in the VDR system 23, as the defect area of the optical disc is reproduced, the PTS value is detected with discontinuity in the PTS detection unit 30 ( S25), or as the VDR system 23 switches to the menu mode while performing the title playback mode, the mode detector 31 detects the current operation mode as the playback standby mode (S26), or the user. When the dubbing pause key is input (S27), after temporarily stopping the dubbing operation (S28), if a lapse of more than a predetermined time has elapsed or if the pause is canceled by the user, The dubbing operation will be resumed from this point.

In addition, when the dubbing operation is paused, when it exits the defect area or when the current reproduction standby mode is switched to the title reproduction mode, the second microcomputer 22 performs the VDR system 23. By controlling the operation of the optical disk, and reproducing the recording operation of the optical disk, and controlling the VCR system 11 through the interface with the first microcomputer 12 to perform the recording operation of the video tape normally. Let's go.

Or more, preferred embodiments of the present invention described above, for the purpose of illustration, those skilled in the art, within the technical spirit and the technical scope of the present invention disclosed in the appended claims below, to further improve various other embodiments Changes, substitutions or additions will be possible.
