Generally, an optical disc capable of recording and storing high quality video data and high quality audio data for a long time, for example, an optical disc such as a rewritable DVD-RW, and the like, and record MPEG video and audio data on the optical disc. Disc recorders (Disc-Recorders) that can be stored or read and reproduced are widely used and commercialized.

Meanwhile, as shown in FIG. 1, a lead-in area, a data area, and a lead-out area are separately allocated to the optical disc. For example, up to 99 titles (Title # 1 to # 99) can be recorded in the data area, and title information (Title # 1_Info to Title # 99_Info) for controlling playback of each title in the lead-in area. Can be recorded and managed as navigation information.

Each title information includes a title start address (Title_SA) and end address (Title_EA), a title name (Title_name), video and audio attribute information (Attribute), and the like.

In the disc recorder, the title name (Title_Name) included in the title information is displayed on the menu screen of the Play List that can be used as a user interface at the user's request. Selects and designates an arbitrary title name, a series of reproducing operations for reproducing the title are performed by searching and referring to the start address, the end address, and the attribute information of the title.

The menu screen of the image is displayed on the screen of an external connected device such as a television. For example, as shown in FIG. 4, the menu screen of the virtual title group (Virtual_Title_Group) editing mode is displayed. do.

In addition, for example, a title name input field ('Title Name') for inputting an arbitrary title name that the user wants to group is displayed on the menu screen of the virtual title group editing mode. Title names of a plurality of titles recorded on the optical disc 10 may be displayed in a list form, and program names for each broadcasting channel may be displayed in a list form using EPG information provided through digital broadcasting. have.

On the other hand, in the microcomputer 13, one of a title name or a broadcast program name displayed in the list form is selected and specified, or the user inputs any title name in the title name input field. For example, when selecting or specifying a title name of 'Drama', as shown in FIG. 5, a plurality of titles (eg, Title # 1, # 4, # 6 .. ) Is grouped into one virtual title group.

In addition, virtual title information (for example, Virtual_Title # 1_Info) corresponding to the virtual title group is generated and recorded and managed in the lead-in area of the optical disc and / or the memory 16 in the apparatus. Index information (eg, Title # 1_Info_ Index, Title # 4_Info_Index, Title # 6_Info_Index ..) for linking with title information corresponding to the plurality of titles may be simply recorded.

For reference, although each title information for controlling reproduction of the plurality of titles may be recorded and managed in the virtual title information, in this case, since the recording capacity of the management information is greatly increased, as described above, each title information It is desirable to record and manage only index information for linkage with the virtual title information.

FIG. 6 is a flowchart illustrating operations of a plurality of title group editing methods according to the present invention.

The menu screen of the image is output and displayed through an external connection device such as a television (S10).

On the other hand, the microcomputer 13 selects and designates either a title name or a broadcast program name displayed in a list form in the menu screen, or the user selects a title name (eg, Drama) in the title name input field. ), The title name recorded in each title information (e.g., Title # 1_Info to Title # 99_Info) is compared with an arbitrary title name selected and input by the user. A plurality of titles having the same title name (eg, Title # 1, # 4, # 6 ... # 99) are selectively searched for (S12).

In addition, the microcomputer 13 sets the searched plurality of titles as one virtual title group, generates virtual title information (Virtual_Title_Info) corresponding to the virtual title group, and generates an optical disc ( The recording management is performed in the lead-in area of the apparatus 10 or the memory 16 in the apparatus. As described above, the virtual title information includes index information for linking with title information corresponding to the plurality of titles. Example: Title # 1_Info_ Index, Title # 4_Info_Index, Title # 6_Info_Index ..) are simply recorded and managed.

Then, when the microcomputer 13 records a new title (S14), for example, a reserved recording operation is performed, the new recorded title name is the title name of 'Drama' set as the virtual title group. If it matches (S15), the newly recorded title is included in one virtual title group, and the title information corresponding to the newly recorded title is stored in previously stored virtual title information (for example, Virtual Title # 1_Info). An update write operation is performed to further include index information for linkage with (S16).

On the other hand, the microcomputer 13, in response to the user's request, the operation of the OS generating unit 14 to display a menu screen of the play list, for example, as shown in FIG.
