This application is a continuation of application Ser. No. 10/797,563, filed on Mar. 11, 2004, now abandoned, which claims the benefit of Korean Patent Application Nos. 2003-15859, filed on Mar. 13, 2003, 2003-19963 filed on Mar. 31, 2003, 2003-69719 filed on Oct. 7, 2003, and 2004-6977 filed on Feb. 3, 2004, in the Korean Intellectual Property Office, and U.S. Provisional Application No. 60/511,100 filed on Oct. 15, 2003, now expired, the disclosures of which are incorporated herein by reference in their entireties.
Video titles are composed of AV data which is recorded on a Digital Video Disc (DVD)-Video disc. Additionally, navigation data which enables a user to select superimposed dialogues or search for scenes while reproducing the video titles is also recorded on the DVD-Video disc.
FIG. 5B is a diagram illustrating a data structure of a hidden title #j which is unit information of the title information according to the present invention.
Referring to FIG. 1A, core mode data 1 and index information 2 are stored on the disc 100. The core mode data 1 comprises audio/video (AV) data that includes a plurality of titles and navigation data which has a plurality of navigation commands for navigating the AV data, similar to a conventional digital video disc,(DVD)-Video disc. The structure of the core mode data 1 meets the requirements of the DVD-Video standard.
For example, the AV data shown in FIGS. 1A, 1B, and 1C is recorded as an AV stream file that is encoded using a Moving Picture Experts Group (MPEG)-2 encoding method. A continuous AV stream file is called a clip stream file. A clip information file corresponds to each clip stream file. Reproduction control information regarding the clip stream file, for example, mapping information which maps a reproduction time and a recording position, is stored in the clip information file. The clip information file that corresponds to the clip stream file is referred to as a clip.
Referring to FIG. 3B, the buffer 20 includes a browsing data buffer 21 which buffers the browsing data, a program data buffer 22 which buffers the program data, a navigation data buffer 23 which buffers the navigation data, an AV data buffer 24 which buffers the AV data, and an index information buffer 25 which buffers the index information.
For example, if the user selects a first title #1, the first title #1 includes title information that designates a first navigation object #1, thereby executing the first navigation object #1. The first navigation object #1 includes a navigation command. When the navigation command is executed, a predetermined playlist is reproduced. After the playlist is reproduced according to the first navigation object #1, the first navigation object #1 indicates a first hidden title #1, and a third navigation object #3 designated by the first hidden title #1 is executed. Here, a hidden title is not directly selected by the user to be reproduced. The hidden title is only reproduced in the order predetermined by the disc manufacturer. For example, a moving picture including an official announcement about a copyright, a moving picture of a trailer broadcasted after a movie ends, etc., can be a hidden title. Because these moving pictures are searched by the user operation and need little be reproduced separately, these moving pictures are set to hidden titles and are reproduced only in the order determined by the navigation command.
After the disc 100 of FIG. 1C is loaded, the reader 10 of the reproducing apparatus reads the index information 2 and transmits the read index information 2 to the application manager 35. The application manager 35 provides instructions from the start up information to indicate a title which is to be initially reproduced. Alternatively, if the user calls a menu and selects a title among the titles shown in the menu, the application manager refers to an entry point of the selected title and transmits an object designated by the selected title to the engine corresponding to the selected title. According to an embodiment of the present invention, because the initial title to be reproduced as instructed by the start up information is a navigation object, in operation 1, an entry point of the navigation object is transmitted to the navigation engine 33. The navigation engine 33 commences the reproduction of the core mode data by transmitting a navigation command contained in the navigation object to the presentation engine 34. In operation 2, another navigation object designated by a first title #1 is reproduced after the navigation object is first executed in the core mode. The navigation object reproduced in operation 2 may be reproduced in operation 3 through a title search. In the same manner, second and third titles #2 and #3 are respectively connected to the browsing object and the program object in operations 4 and 5, and the titles can be reproduced when the user provides a command to reproduce them.
In operation 6, the navigation object designated by the first title #1 is connected to a browsing object via a first hidden title #1. In other words, the mode conversion is performed with reference to the first hidden title #1. In this case, the navigation engine 33 transfers control to the application manager 35. The application manager 35 provides instructions to the browsing engine 31 to reproduce the browsing object designated by the first hidden title #1. In this way, the hidden title cannot be directly accessed by the user. Because a title can include data in a variety of modes through the mode conversion with reference to the hidden title, the user can reproduce the title without regard to the mode conversion.
FIG. 5B is a diagram illustrating a data structure of a hidden title #j according to an embodiment of the present invention.
Referring to FIG. 5B, the hidden title #j also includes access type information that acts as attribute information, and indicates an entry point of a title. The access type information indicates whether the user can directly control the title to be reproduced. Because the hidden title #j prohibits the user's direct access, the access type information represents the title #j as “hidden”. The access type information further contains information that indicates whether a title number of the “hidden” title is displayed to the user. That is, the access type information displays the title number when the title number is allotted to the hidden title and does not display the title number when the title number is not allotted to the hidden title.
