Description of the Invention: [Technical Field] The present invention relates to a subtitle processing technique, and more particularly to a method of displaying subtitles. [Prior Art] Subtitle is a technology widely used in the field of audio and video broadcasting such as television and movies. The appearance of subtitles makes it easier for viewers to understand the audio and video content being played. In the audio and video program playback, the spoken content in the program, or any other additional information related to the content of the program, is displayed by text. For example, a typical TV series will simultaneously display the words that the characters in the TV series are saying in the form of subtitles, and the music programs usually display the lyrics in the form of subtitles. : Often in the data flow of the release source, the predetermined subtitle data M is reduced to the video stream by means of codec, and when the end user is reached, the subtitles can be displayed synchronously when the video stream is played. With the advent of Internet @ and the development of P2P technology, it is not only possible to watch TV signals on TV or watch movies in cinemas. At present, it is possible to convert various audio and video signals, such as television signals, movie signals, and radio broadcast signals, into "received, and then transmit them to a personal computer (PC) through P2P technology, and finally watch TV, movies, etc. directly on the PC. Video content or listening to the radio broadcast temple instant audio content. Figure 1 is a schematic diagram showing the display of subtitle data in the prior art. Figure i can be used by the second sender to compress and mix the subtitle data and the video stream to form data, After that, the data flow is sent to the PC through the Internet and other media, and after 5, 2008,997, the data flow is parsed by the PC, and the video stream and the subtitle data are played. It can be seen that the subtitles are mixed in the prior art. In the video stream, when the subtitle data is displayed, the user can only passively watch the subtitle of the video ^, and cannot interact with the subtitle. '11 Often, the desire of the PC user to perform interaction will be compared. Strongly, they have been accustomed to using a mouse, keyboard and other computers (four) to carry out various interactive operations, so the user can watch or listen to the program on the PC. You may also want to interact with subtitles through computer peripherals such as mouse and keyboard. For example, when playing a program on a PC, the user may be very interested in a certain protagonist in the program, and would like to know k. Basic information of the 7L protagonist'' However, in the current technology, the user can only passively watch the subtitles on the video, but cannot use the subtitles to implement the user interaction function, and thus can not directly use the subtitles to obtain relevant information about the protagonist. Therefore 1 The subtitle display method of the prior art brings great inconvenience to the user. [Invention] The main object of the present invention is to propose a method for displaying subtitles so that the user can interact with the subtitles. To achieve the above objective, the technical solution of the present invention is implemented as follows: A method for displaying no subtitles, the method comprising: adding a window on a visual display interface, and superimposing the window on the video display interface; Β, the subtitles are displayed in the superimposed window. As can be seen from the above technical solution, in the present invention, the first I is displayed in the video. A new window is added on the surface, and the window is superimposed on the video display interface; after 6200849997, the subtitles are displayed in the superimposed window. It can be seen that after applying the present invention, since the video stream is no longer parsed Display subtitles, but add a window and display subtitles in the window: so the subtitles of the present invention are independent of the video data, and the user no longer passively receives the subtitles, but can interact with the subtitles to trigger various operations. In addition, since there are many mature operation commands for the window, the present invention is also very convenient to perform interaction. p [Embodiment] In order to make the object, technical solution and advantages of the present invention more clearly, the following The present invention will be further described in detail with reference to the accompanying drawings and specific embodiments. The main idea of the present invention is: firstly, adding a window to the video display interface, and superimposing the window on the video display interface; Subtitles are displayed in the superimposed window. Therefore, the present invention displays subtitles by displaying subtitles in the window instead of parsing the video stream. Therefore, the subtitles of the present invention are independent of the video data, and the U user no longer passively receives the subtitles, but can interact with the subtitles. To trigger various operations. Moreover, the implementation of the present invention is also very convenient due to the many mature operational commands for the window. 2 is a flow chart of an exemplary method of displaying subtitles in accordance with the present invention. As shown in FIG. 2, the method includes: γ step 2 01 · adding a window on the video display interface, and superimposing the window on the video display interface; Step 202: displaying the subtitle in the superimposed window. Here, it is preferable to predetermine the superposition of the window on the video display interface 7 200849997 and then superimpose the window at the predetermined superimposed position on the video display interface. More preferably, the predetermined superimposed position may be located in the video display interface. The bottom: the top, the top, or the bottom right corner. The body also depends on the position of the display screen. The position on the display interface is determined by four values: left (left), upper (but 0), width (Width), and height (Height). In the same time, you can use the arithmetic expression to represent the position of the window. In the calculation formula, you can use scr-width to represent the video width and scr-height to represent the video height. In this case, you can implement any video display interface. Subtitles are displayed at the location. For example, if you want to display a subtitle from the right side of the video, and the display width is 150, a subtitle is displayed at the upper boundary of the video and the height is 12〇. You can set the left: scr-Width_2〇〇: 1 〇 width: 15 〇 high: 12 〇 to achieve. Here, the video can be either a video based on an instant stream or a normal video file stored locally. When the video is a video stream based on the instant data stream, the user terminal of the video display interface receives the control stream from the remote end, and the control stream includes the overlay window command and the subtitle; and then the user terminal according to the overlay window command. Adding a window to the video display interface and superimposing the window on the video display interface, thereby using the most recent window to display the subtitles included in the control stream. The overlay window finger 8 may specifically include a CreateWindow command and information indicating a position of the window overlay. The CreateWindow command is a standard command to open a new window, indicating the view, and the information of the location is used to indicate the superimposed position of the window on the video display interface. The control flow including the overlay window command and the subtitle can be transmitted to the client at the same time as the instant view, or can be transmitted to the client at the same time. When the subtitle content is directly related to the video content, for example, when the subtitle is the translation of the video content, the video content and the subtitle need to be synchronized during playback. At this time, a timer can be set to control the synchronization of the video playback time and the subtitle display time. When the content of the subtitle is not directly related to the video content, such as when the subtitles play the introduction information of the protagonist, or the instant news information, the subtitles may be out of sync with the video content. When the video is stored in the local video file, an overlay window command can be created locally on the video player, and the overlay window command and the video file are associated. The overlay window command also preferably includes a CreateWind〇w command and a message indicating the position of the window overlay, wherein the CreateWindow command is a standard command to open a new window, and the information indicating the position of the window overlay is used to indicate the superimposed position of the window on the video display interface. When the video file is played, the associated overlay window command is executed at the same time, a new window pops up, and the window is superimposed on the video display interface to display the subtitles in the window. At this time, the subtitle can be either a subtitle transmitted from the server by the remote end or a subtitle saved locally. Whether the video is based on the instant data stream or the local video file, the present invention can be utilized based on the window to display the subtitle in the superimposed window instead of passively parsing the subtitle data from the data flow. Various interactive operations of subtitles. For example, you can open a new window, open a new browser interface, open a new application, close a running application, close an existing browser interface, close an existing window, close an existing window, etc. Etc., so that users can interact richly with subtitles. 9 200849997 In the above process, whether it is based on the video of the instant data stream or the local normal video file, the present invention can display the subtitles in the superimposed window in various ways. For example, the text can be first drawn by the GDI in the superimposed window, and then the scrolling effect of the displayed text and words can be realized by changing the display position of the drawn text in the window. Here, you can use a variety of GDI to draw text, such as 訏 (10) "乜 API, or TextOut API, etc. 〇 The following uses the DrawText API as an example to explain how to use GDI to draw text. Those skilled in the art can be aware As such, this is merely exemplary, and is not intended to limit the manner in which text is rendered using GDI. Figure 3 is a schematic diagram showing the display of subtitles in a superimposed manner using the DrawText API, in accordance with an exemplary embodiment of the present invention. The subtitles are displayed in the window. When using the DrawText API, first use DrawText Αρι to place the text on the coordinates (\, 乂) at the window, and set a timer through SetTlraeq. When the timer dies (four), the X is reduced accordingly. Small 'repaint the window' to achieve the effect of subtitle scrolling to the left. Similarly, if you increase the number of * 〜 丹 丹 丹 丹 丹 丹 丹 丹 丹 丹 丹 字幕 字幕 字幕 字幕 字幕 字幕 字幕 字幕 字幕 字幕 字幕 字幕 字幕 字幕 字幕 字幕 字幕 字幕 字幕 字幕 字幕 字幕 字幕Throughout the subtitle scrolling in other directions, you can increase or decrease the X or y value accordingly. In the message loop of the 4 windows, respond to the Li-LBUHONUP message. If this is obtained from the moon, it means that the user clicks on the word, and the bell can be used to perform the related actions through the demand. The text is displayed by GDI to display the subtitles. It is very clean and takes up a small amount of system resources, but it is difficult to achieve subtitles and texts. Preferably, it is also possible to create a displacement control item in the superimposed window, and then use the row 200849997 The version of the interactive y engine control item displays the subtitles. The following uses the HtmlView control item as an example to explain how to display the subtitles by using typographic interaction. Those skilled in the art can realize that 疋 is not consuming, and is not used for utilization. The typographical interactive engine controls any restrictions on how the subtitles are displayed. Ο L)
