The present invention relates to a video recording and reproducing system, and more particularly to an optical disc title copying method in a combo type system.

Video recording / reproducing apparatus capable of recording a broadcast signal on a recording medium or reproducing the recorded broadcast signal has been expanded as a function of digitalization and compression of broadcast signals. Such video recording / reproducing devices are being developed to support the use of various video sources such as satellite broadcast signals, cable broadcasts, and network broadcasts over the Internet. Data storage on the same optical media medium has been reached. Such an optical media medium has almost no deterioration in image quality according to the usage period, and is rapidly replacing conventional analog image recording media because it can store high quality images and multi-channel audio data. As such, an optical media medium such as a DVD title that stores image data and audio data can store data of hundreds of Mbytes to several Gbytes, and thus a mass storage device has recently been used in a video recording / reproducing apparatus having a function of simply recording / playing back. It employs many functions that make it easy to store or read a huge amount of data by adopting an in-hard disk drive. The video recording / reproducing apparatus has a function capable of reproducing A / V signals and is configured to each perform an independent function. As a representative example of a DVD / HDD video recording / reproducing apparatus, a DVD ROM for reproducing data recorded on a disc and a hard disk drive for recording and reproducing data are combined in one case. At this time, the DVD ROM and the HDD each have an interface capable of transmitting and receiving data while performing independent functions. Generally, a DVD ROM plays back each data recorded on an optical disc recording medium such as a DVD, an audio CD, a video CD and an MP3 CD.

The DVD / HDD video recording / reproducing apparatus may receive a broadcast signal from an external source to record data on the HDD or output the data externally, or may record data reproduced from a DVD ROM to the HDD.

Here, the method of recording data reproduced on a DVD ROM onto a HDD has a problem in that titles stored on the DVD ROM cannot be copied in the order desired by the user because the titles recorded on the DVD ROM are sequentially reproduced and recorded on the HDD.

In addition, since a DVD ROM is sequentially played and recorded on the HDD, the user cannot copy only a desired title to the HDD.

SUMMARY OF THE INVENTION An object of the present invention is to solve such a problem of the prior art, and to set the playback order of titles stored on the optical disc, and to reproduce the optical disc based on the playback order, and to store the optical disc in the hard disk drive. It is to provide a method of copying a disc title.

In order to achieve the above object, the present invention provides an optical disc title copying method of a combo-type video recording and reproducing apparatus in which an optical media player and a hard disk drive are built in. Receiving an input of a copy key, reading at least one title information stored on an optical disc from the optical media player according to the copy key input, and setting an order of playing the read title information. And reproducing a title in the optical disc based on the reproduction order set through the interface, and storing the title in the optical disc in the hard disk drive.

Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings.

1 is a block diagram schematically illustrating a DVD / HDD combo system having a DVD player and a hard disk drive for explaining a DVD title copying method according to a preferred embodiment of the present invention.

Referring to FIG. 1, the combo system includes a switching unit 100, an MPEG encoder unit 110, a hard disk drive 120, a flash ROM 130, a controller 140, a digital signal processor 150, and an optical media player. 160.

The switching unit 100 receives various image data / audio data sources from the outside or outputs the image data source output from the digital signal processing unit 160 to the outside (for example, a monitor screen) and outputs from the control unit 140. Outputs the OSD screen to the outside.

In addition, the switching unit 100 receives external signal sources such as components and composites applied from broadcast signals and video (not shown) and selectively connects them to functional blocks in the combo system. For example, when an external signal source applied from an external device such as video is a component or a composite signal, it is applied to the MPEG encoder unit 110.

The MPEG encoder 110 converts an analog form of an image data source applied from the switching unit 100 into an analog form and then compresses it into an MPEG format. In general, the MPEG format image data has a compressed form in order to reduce the amount of space stored when the image data is stored in a storage medium such as the hard disk drive 120.

The hard disk drive 120 records video / audio data having an MPEG format in the form of a file.

The flash ROM 130 stores an operating system (OS) and an application program for operating the optical media player 170. The flash ROM 130 stores image / audio data stored in the form of a file on the hard disk drive 120, and the corresponding application. Displays information (icon, title name, recording time, file size, etc.) on the screen through an OSD screen-type menu and sets the playback order of the titles stored on the DVD disc when copying the DVD title to the hard disk drive 120. And an application program for displaying an OSD screen.

The controller 140 stores the MPEG data output from the MPEG encoder unit 110 to the hard disk drive 120 or the video / audio stored in the DVD disk loaded in the hard disk drive 120 or the optical media player 160. The data is applied to the digital signal processor 150 to read the data, or the data is received from the DVD disk loaded in the optical media player 160 and stored in the hard disk drive 120.

In addition, the controller 140 may play back the titles stored on the DVD disc and execute an application program stored in the flash ROM 130 to copy the titles stored on the DVD disc to set the playback order of the titles stored on the DVD. Outputs the screen to an external display device such as a monitor.

The digital signal processor 150 receives the MPEG format image data stored in the hard disk drive 120 through the control unit 140 to decode it and converts the image data into a video format (for example, NTSC / PAL). The converted signal can be reproduced in an image display device such as a monitor.

The optical media flare 160 reads out image data and audio data from the DVD disc and applies the same to the controller 140. Image and audio data applied to the controller 140 is stored in the hard disk drive 120 or is applied to the digital signal processor 150 to be reproduced.

A process of copying a title stored in the optical disc to the hard disk drive 120 by the combo system having the above configuration will be described with reference to FIG. 2.

2 is a flowchart illustrating a DVD title copy process according to a preferred embodiment of the present invention.

2, after the DVD disc is loaded into the optical media player 160 (S200), if there is a request to copy at least one or more titles stored in the DVD disc to the hard disk drive 120 (S202), the controller 140 searches for title information in the DVD disc loaded in the optical media player 160 (S204).

Then, the controller 140 configures an OSD screen for setting the playback order of the retrieved title information using the program stored in the flash ROM 130 and then displays it on the device (S206).

Subsequently, the controller 140 receives data from the optical media player 160 based on the set playback order, provides the data to the digital signal processor 150, and receives the data from the optical media player 160 on the hard disk drive 120. The data is stored (S208).

That is, the controller 140 controls the optical media player 160 to read data from the DVD disc based on the playback order, thereby providing the digital signal processor 150 with data output from the optical media player 160. In addition, it is stored in the hard disk drive 120. The digital signal processor 150 decodes data applied from the controller 140 and converts the data into a video format (eg, NTSC / PAL). The converted signal may be reproduced in an image display apparatus such as a monitor through the switching unit 100.

According to the present invention, by setting the playback order when copying the titles stored in the DVD disc to the hard disk drive in addition to the playback, by playing the DVD disc and copying it to the hard disk drive according to the playback order, Not only can you play back titles on DVD discs in order, you can also copy them to a hard disk drive.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

As described above, the present invention sets the playback order when copying titles stored in the optical disc to the hard disk drive in addition to the playback, and reproduces the optical disc and copies it to the hard disk drive based on the playback order. In addition, the user's convenience can be enhanced by providing the user with an interface for copying the titles in the optical disc in the desired order as well as copying it to the hard disk drive.
