This application claims the benefit of Korean Patent Application Nos. 2003-69023 filed on Oct. 4, 2003, and 2004-16103 filed on Mar. 10, 2004, in the Korean Intellectual Property Office, the disclosures of which are incorporated herein by reference in their entirety.
Referring to FIG. 1, a text based subtitle file 100 includes dialog information 110, presentation information 120, and meta data 130 a and 130 b. The dialog information 110 includes script text, the output start time of the text, the output end time, stylegroup or style information to be used to render text, text change effect information such as fade-in/fade-out, and a formatting code for text.
The meta data 130 a and 130 b is additional information regarding moving pictures, and includes information required to perform additional functions other than outputting a subtitle.
Output region information (l, t, w, h) 210 indicates a region in which text is to be output, and indicates that the region has coordinates (l, t) as a start position, with a width w and a height h. Output start position information (x, y) 221 indicates a reference point when text is output on the screen, and indicates that the reference point should be within region (l, t, w, h). Text alignment information 222 specifies the alignment method of the text. The text may be left-justified, center-justified or right-justified. When the text is left-justified, it extends rightward from the output start position (x,y). When the text is center-justified, it is centered around the output start position (x,y). When the text is right-justified, it extends leftward from the output start position (x,y). In FIG. 2, an example is shown in which the text is output in a left-justified manner.
A formatting code 280 and character data 290 are included in the dialog information 110. The formatting code 280 may include code for line changes, bolding, Italicizing, and underlining text, and the character data 290 is script text information to be displayed as the subtitle. The output direction of text may be defined as (left→right, top→bottom) or (top→bottom, right→left). In FIG. 2, the output direction is (left→right, top→bottom). The various information described above, excluding the formatting code 280 and the character data 290, is included in the presentation information 120.
There are a variety of methods of forming a style and a stylegroup to indicate style information to be used to render and display each script sentence included in the dialog information 110.
FIG. 5A illustrates an example of a markup tag used to display a subtitle in accordance with an embodiment of the present invention. A <text> tag is used as a unit to classify scripts to be output on the screen. Attribute information included in the <text> tag includes “start,” which indicates a time when the output of text starts, and “end,” which indicates a time when output ends, as time information for screen output, “effect,” which indicates change effects to be applied to text such as fade-in/fade-out, and “stylegroup”, which indicates style information to be used to render script text. Also, a script to be output on the screen is recorded in the <text> tag.
FIG. 5B illustrates another example of a markup language tag used to display a subtitle in accordance with an embodiment of the present invention. Referring to FIG. 5B, a <text> tag specifies a style instead of a stylegroup to be used to render script text. In this case, the script text included in the <text> tag is rendered using a default style “Script” among a plurality of styles included in a stylegroup specified by the user.
In a process of forming style information to be used for rendering the script “Text 2”, since the script “Text 2” indicates the stylegroup “Script”, information to render text included in the stylegroup “Script” is selected. If the style “Large” is selected by the user, selection information that is included in the style “Large” is selected. Then, the selectable information of the style “Large” of the stylegroup “Script” is applied to the information to render text of the stylegroup “Script” to form a complete set of style information.
FIG. 9 is a block diagram of a text based subtitle processing apparatus according to an embodiment of the present invention. The text based subtitle processing apparatus includes a text subtitle processing unit 920 to render text as needed. The text subtitle processing unit 920 includes a text subtitle parser 921 to extract presentation information and dialog information from a subtitle, and a text layout/font renderer 922 to generate an image to be output by rendering text according to the extracted presentation information.
After text based subtitle information and font information are read from a disc 900 and stored in a buffer 910, the subtitle information is transmitted to the text subtitle parser 921 of the subtitle processing unit 920, where presentation information and dialog information are extracted, and the font information is transmitted to the text layout/font renderer 922. The extracted information is transmitted to the text layout/font renderer 922 and a composition buffer 933 of a presentation engine 930. The text layout/font renderer 922 generates an image to be displayed on a display apparatus by rendering text using the transmitted style information and font information, and transmits the image to an object buffer 934 included in the presentation engine 930.
The subtitle in the form of a bitmap image is read from the disc 900, input to a coded data buffer 931, processed by a graphic processing unit 932, and transmitted to the composition buffer 933 and the object buffer 934. The composition buffer 933 receives the object composition information transmitted by the text subtitle parser 921 and the bitmap subtitle data processed by the graphic processing unit 932, and transmits control information for screen output to the graphic control unit 935. The object buffer 934 combines the bitmap subtitle data processed by the graphic processing unit 932 and the rendered text subtitle object received from the text layout/font renderer 922, generates a graphic plane 940, and outputs the graphic plane 940 to the display apparatus by referring to a color lookup table (CLUT) 950.
