PRIORITY INFORMATION [0001] This is a continuation application of application Ser. No. 11/033,494 filed Jan. 12, 2005, the entire contents of which are hereby incorporated by reference. [0002] This application claims the benefit of U.S. Provisional Application No. 60/542,850, filed on Feb. 10, 2004; U.S. Provisional Application No. 60/542,852, filed on Feb. 10, 2004; and U.S. Provisional Application No. 60/543,328, filed on Feb. 11, 2004, the entire contents of which are hereby incorporated by reference. This application also claims the benefit of Korean Patent Application No. 10-2004-0017935, filed on Mar. 17, 2004, which is hereby incorporated by reference as if fully set forth herein. BACKGROUND OF THE INVENTION [0003] 1. Field of the Invention [0004] The present invention relates to a recording medium and a method and apparatus for decoding a text subtitle stream recorded on a recording medium. [0005] 2. Discussion of the Related Art [0006] Optical discs are widely used as an optical recording medium for recording mass data. Presently, among a wide range of optical discs, a new high-density digital video disc (hereinafter referred to as "HD-DVD"), such as a Blu-ray Disc (hereafter referred to as "BD"), is under development for recording high definition video and audio data. Currently, global standard technical specifications of BDs, which are known to be the next generation HD-DVD technology, are under establishment as a next generation optical recording solution that is able to have data significantly surpassing the conventional DVD, along with many other digital apparatuses. [0007] Accordingly, optical reproducing apparatuses having the Blu-ray Disc (BD) standards applied thereto are also being developed. However, since the Blu-ray Disc (BD) standards are yet to be completed, there have been many difficulties in developing a complete optical reproducing apparatus. Particularly, in order to effectively reproduce the data from the Blu-ray Disc (BD), not only should the main AV data as well as various data required for a user's convenience, such as subtitle information as the supplementary data related to the main AV data, be provided, but also managing information for reproducing the main data and the subtitle data recorded in the optical disc should be systemized and provided. [0008] However, in the present Blu-ray Disc (BD) standards, since the standards of the supplementary data, particularly the subtitle information, are not completely consolidated, there are many restrictions in the full-scale development of a Blu-ray Disc (BD) basis optical reproducing apparatus. And, such restrictions cause problems in providing the supplementary data such as subtitles to the user. SUMMARY OF THE INVENTION [0009] Accordingly, the present invention is directed to a text subtitle decoder and a method for decoding text subtitle streams recorded on a recording medium that substantially obviates one or more problems due to limitations and disadvantages of the related art. [0010] An object of the present invention is to provide a recording medium including a dialog style segment defining a set of user control styles, each of which is able to change at least one of region presentation properties specified by a region style. [0011] Another object of the present invention is to provide a method and an apparatus for decoding a text subtitle stream by using a user control style which changes at least one of the region presentation properties specified by a region style. [0012] Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings. [0013] To achieve these objects and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, a recording medium includes a data area storing at least one text subtitle stream, each of which includes a dialog style segment defining a set of region styles to be applied to at least one region of dialog text. Each text subtitle stream may further include at least one dialog presentation segment, each of which contains at least one region of dialog text and is linked to at least one of the set of region styles. The dialog style segment further defines a set of user control styles for each region style, where each user control style is selectable and is configured to change at least one of region presentation properties specified by a corresponding region style. For example, each user control style may specify a direction and a magnitude of a change in at least one of a region horizontal position, a region vertical position, a text horizontal position, a text vertical position, a line space, and a font size, all which are specified in the corresponding region style. [0014] In another aspect of the present invention, a method and an apparatus for decoding a text subtitle stream recorded on a recording medium are provided. A subtitle loading buffer loads the text subtitle stream, which includes a dialog style segment defining a set of region styles and at least on dialog presentation segment. Each dialog presentation contains at least one region of dialog text and is linked to at least one of the set of region styles. The dialog style segment further defines a set of user control styles for each region, where each user control style is selectable and is configured to change at least one of region presentation properties specified by a corresponding region style. A text subtitle decoder is able to decode each dialog presentation segment using the linked region style and one of the set of user control styles defined in the dialog presentation segment. [0015] Each user control style may specify a direction and a magnitude of a change in the region presentation properties specified by the corresponding region style. The region presentation properties include at least one of a region horizontal position, a region vertical position, a text horizontal position, a text vertical position, a line space, and a font size, which are specified in the corresponding region style. [0016] It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. BRIEF DESCRIPTION OF THE DRAWINGS [0017] The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the principle of the invention. In the drawings; [0018] FIG. 1 illustrates a file structure of data files recorded on an optical disc according to an example of the present invention; [0019] FIG. 2 illustrates data storage areas of an optical disc according to an example of the present invention; [0020] FIG. 3 illustrates a text subtitle and a main image presented on a display screen when a text subtitle stream and a main AV stream are reproduced; Continue reading about Recording medium and method and apparatus for decoding text subtitle streams...
