Brief Patent Description - Full Patent Description - Patent Application Claims
[0001] This application is a continuation of U.S. patent application Ser. No. 10/911,731 filed on Aug. 5, 2004, the entirety of which hereby is incorporated herein by reference. [0002] This application claims the benefit of Korean Patent Application No. 10-2004-0000633, filed on Jan. 6, 2004, which is hereby incorporated by reference. BACKGROUND OF THE INVENTION [0003] 1. Field of the Invention [0004] The present invention relates to a recording medium having at least one text subtitle stream for reproduction of images recorded thereon as well as methods and apparatuses for reproduction and recording. [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 optical recording medium (HD-DVD), such as the Blu-ray Disc (hereafter referred to as "BD"), is under development for writing and storing high definition video and audio data for a long period of time. [0007] Currently, global standard technical specifications of the Blu-ray Disc (BD), which is 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. 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. [0008] Most particularly, in order to effectively reproduce the data from the Blu-ray Disc (BD), not only information on a structural data file of the data recorded in the Blu-ray Disc (BD), but also information for effectively forming and managing the data file should be systemized and provided. However, in the present Blu-ray Disc (BD) standards, since the standards of the auxiliary 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 reproducing the data stream and providing the data stream to the user. SUMMARY OF THE INVENTION [0009] The present invention relates to a recording medium storing a data structure. [0010] In one embodiment, the data structure includes at least one text subtitle stream including text data for a text subtitle and style information containing user selectable style information. The style information includes at least one set of display properties of the text subtitle and the user selectable style information specifies which of the display properties are allowed to be changed. [0011] Another embodiment of the present invention relates to a method of generating text subtitle streams. [0012] In one embodiment, the method includes generating at least one text subtitle stream. Each text subtitle stream includes text data for a text subtitle and style information containing user selectable style information. The style information includes at least one set of display properties of the text subtitle and the user selectable style information specifies which of the display properties are allowed to be changed [0013] A still further embodiment relates to an apparatus for reproducing text subtitle streams. [0014] In one embodiment, the apparatus includes a driver configured to read data. The data includes at least one text subtitle stream. Each text subtitle stream includes text data for a text subtitle and style information containing user selectable style information. The style information includes at least one set of display properties of the text subtitle and the user selectable style information specifies which of the display properties are allowed to be changed. [0015] The present invention relates to additional embodiments of the recording medium and method and apparatus of reproducing the recording medium. [0016] Furthermore the present invention relates to methods and apparatuses for generating or creating test subtitle streams, and/or recording test subtitle streams. 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 embodiments of the invention and together with the description serve to explain the principle of the invention.
