BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates to information technology (IT), and more particularly, to a video program subtitle text recording method and system, which is designed for use in conjunction with a video playback platform, such as a digital TV, a multimedia player, a desktop computer, a notebook computer, and so on, for providing a video program subtitle text recording function that allows the user to record the subtitle text embedded in a video program displayed on the video playback platform into an electronic text file, so that the user can later retrieve the electronic text file and view the recorded subtitle text through a computer platform, such as a desktop computer, a notebook computer, a tablet PC, a PDA (Personal Digital Assistant), an intelligent mobile phone, and the like. [0003] 2. Description of Related Art [0004] Digital TV is a new video broadcast technology that can reproduce a digital video stream and display it on a digital display, such as an LCD (Liquid Crystal Display) for viewing by the user. In practical use, a digital TV is typically connected to an external or built-in video source, such as a wireless set-top-box (STB), a cable TV receiver, a DVD (Digital Versatile Disc) player, or the like. [0005] Typically, most video programs are embedded with subtitles that represents a written form of the speeches in the video program or shows related messages about the video program. For example, in the case of an English-speaking video program, such as an English-teaching program, is broadcast in a Chinese-speaking country, the video program is typically embedded with Chinese-translated subtitles; in the case of a video program that teaches cooking, the video program is typically embedded with a written form of the recipes; and in the case of a music-related video program, the video program typically uses subtitles to show the lyrics of the songs. [0006] In the use of digital TV, there exists a need for the user to record the text contents the subtitles in the video program, so that the user can keep the subtitle text contents as a reference without having to view it again by turning on the TV. Traditionally, the user can do this only by shorthand writing. However, since the subtitles typically run very quickly, it would be highly difficult or next to impossible for the user to record all the subtitle contents by shorthand writing. SUMMARY OF THE INVENTION [0007] It is therefore an objective of this invention to provide a video program subtitle text recording method and system, which is capable of automatically recording all the subtitle text embedded in a video program into an electronic text file, so that the user can later view the subtitle text through a PC or any PC-compliant electronic devices, without requiring the user to do shorthand writing. [0008] The video program subtitle text recording method and system according to the invention is designed for use in conjunction with a video playback platform, such as a digital TV, a multimedia player, a desktop computer, a notebook computer, and so on, for providing a video program subtitle text recording function that allows the user to record the subtitle text embedded in a video program displayed on the video playback platform into an electronic text file, so that the user can later retrieve the electronic text file and view the recorded subtitle text through a computer platform, such as a desktop computer, a notebook computer, a tablet PC, a PDA (Personal Digital Assistant), an intelligent mobile phone, and the like. [0009] The video program subtitle text recording method and system according to the invention is advantageous to use in that it allows the user to automatically record all the subtitle text in a video program into an electronic text file without requiring the user to do shorthand writing. BRIEF DESCRIPTION OF DRAWINGS [0010] The invention can be more fully understood by reading the following detailed description of the preferred embodiments, with reference made to the accompanying drawings, wherein: [0011] FIG. 1 is a schematic diagram showing the application architecture and modularized component model of the video program subtitle text recording system according to the invention; [0012] FIG. 2A is a schematic diagram showing an example of a block of subtitle text embedded in a video program; [0013] FIG. 2B is a schematic diagram showing an example of the contents of an electronic text file that records the subtitle text shown in FIG. 2A; [0014] FIG. 3A is a schematic diagram showing an example of a line of English subtitle text embedded in a video program; and [0015] FIG. 3B is a schematic diagram showing an example of the contents of an electronic text file that records the English subtitle text shown in FIG. 3A along with a line of Chinese-translated text. DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS [0016] The video program subtitle text recording method and system according to the invention is disclosed in full details by way of preferred embodiments in the following with reference to the accompanying drawings. [0017] FIG. 1 is a schematic diagram showing the application architecture and modularized component model of the video program subtitle text recording system according to the invention (as the part enclosed in the dotted box indicated by the reference numeral 100). As shown, the video program subtitle text recording system of the invention 100 is designed for use with in conjunction with a video playback platform 10, such as a digital TV unit, a multimedia player, a desktop computer, a notebook computer, and so on, for providing a video program subtitle text recording function that allows the user to record the subtitle text embedded in a video program displayed on the video playback platform 10 into an electronic text file 300, so that the user can later view the subtitle text through a computer platform 30, such as a desktop computer, a notebook computer, a tablet PC, a PDA (Personal Digital Assistant), an intelligent mobile phone, and the like. [0018] In practical application, the video playback platform 10 is connected to an external or built-in video source 20, such as a wireless set-top-box, a cable TV receiver, a DVD (Digital Versatile Disc) player, or the like, which is capable of outputting a video stream 21 to the video playback platform 10 for the video playback platform 10 to display the contents of the video stream 21 on the screen 11 thereof. [0019] As shown in FIG. 1, the modularized component model of the video program subtitle text recording system of the invention 100 comprises: (a) a video stream fetching module 110; (b) a subtitle text extracting module 120; (c) a text format conversion module 130; and (d) a file building module 140; and can further optionally include a date/time insertion module 210 and a translation module 220. [0020] The video stream fetching module 110 is capable of fetching a bifurcated part of the video stream 21 that is being inputted to the video playback platform 10 from the video source 20 for processing by the video program subtitle text recording system of the invention 100.
