Description of the Invention: [Technical Field] The present invention relates to digital broadcasting, and more particularly to a method for continuously playing a plurality of digital audio and video files on a playback device t. [Prior Art] Currently, digital playback devices, such as digital cameras, are often provided with playback functions for still images, sounds, and dynamic video. However, for continuous playback, that is, to play in a slideshow, it is limited to still images and sounds. Therefore, when the user wants to browse the contents of multiple digital audio and video files (such as AVI, MPEG, ASF, etc.) at a time, it is necessary to operate one file separately, which is very inconvenient for the user. SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a method for continuously playing a plurality of digital video files in a playback device to improve the usability of the playback device. Another object of the present invention is to provide a method for continuously playing a plurality of digital audio and video files in a playback device, which can make the playback process smoother, without the occurrence of a medium-long phenomenon, and to force the placement (four) continuously. Playback function. To achieve the foregoing objective, the method for continuously playing a plurality of digital video files of the present invention has the following steps: selecting a plurality of digital audio and video files stored in the playback device via a user interface; and analyzing the digital audio and video files 'To obtain one of the corresponding digital audio and video files, one of the 1248552 can be played, decode according to a playback order (also (7) also) and play the digital audio and video files, and update one of the corresponding digital audio and video files in the process of playing. Remaining playing time, wherein the digital video files include a first and a second video playing, the second scene sound file is immediately after the first video sounding in the playing sequence; and when the first video file is When the remaining play time reaches a predetermined time, decoding of the second video file is started. In order to further describe the contents of the present invention, the embodiments of the present invention will be described in detail with reference to the drawings. [Embodiment] FIG. 1 is a preferred implementation ship chart of a method for continuously playing a plurality of digital video files of the present invention. In this implementation, the method is gamuted to a digital playback device, such as a touch field. The age reading here can be a variety of viewing formats supported by the digital playback device. As shown in FIG. 3, the method includes the following steps: Step 11: Select a plurality of digital video files stored in the playback device via a user interface; Step 12: Analyze the video files, to obtain each One of the digital audio and video rights corresponding to the playable time; Step 13: Decoding and playing the digital video and audio symbols according to the play sequence, and updating the remaining play time corresponding to each of the digital audio and video files during the playing process; 14: judging whether the remaining playing time of the currently played video file reaches the predetermined time, if the reward jumps back to step 13, if yes, continue to the step 1248552 step; Step 15: determine whether the currently played video file is the last in the playing order a video file, if yes, skip to step 17, if otherwise continue the column step; step 16: start decoding the next audio and video file to be played, and jump back to step 13; and step 17: continue to play the last video file, End the process. In step 11, the user interface is provided by the playback device, and the user can operate the playback device. Figure 2 is a schematic diagram of one embodiment of a user interface of a playback device. The three large boxes in Figure 2 represent the playback device and show the county. In operation, the money passes through, and even the operation menu of the video player, select 丨 (select video files) or 2 (play all). If you choose! , then enter the child age menu, the list of all digital audio and video lions. After the selection of the ~~ slot is completed, playback starts (ie, step 13). The time displayed in the upper left corner of the ^ is the time when the video lion currently playing can be played (= step 12), the time in the upper right corner represents the playback time of the current playback (updated by step 13), and the lower right corner is displayed. Face, ^ a little video file, and currently play to the first few. In addition, if you select 2 in the operation menu of the continuous thief, you can directly play it, as shown in Figure 2. The playback order is determined to be randomly selected in another embodiment according to the order of selection of the numbers β 步骤 in step 11. In another embodiment, the play sequence I248552 is determined based on the file name (e.g., in alphabetical or numbered order) or the file format (e.g., which format is first broadcast) of the digital video files. In addition, in step 13, the remaining playback time of each digit & file is updated in real time during playback as a basis for judging when to start pre-solving the next video file (i.e., step 14). In another embodiment, the instant update during playback is the played temple between the digital audio and video files, and the remaining playback time of each digital audio and video file is the difference between the playable time and the played time. The mechanisms provided in steps 14 through 17 are to ensure that the playback device maintains smooth playback without being interrupted for too long when moving from a video file to a down-picture channel. The method is that if the currently playing scene file is not the last video file in the order of broadcasting (determined by step 15), then according to the remaining playing time updated in step 13 immediately, the currently playing video file is broadcasted. Before the end (that is, when there is a predetermined time left) (determined by the step Μ), the next year starts the decoding of the next to-be-played video file (ie, step (6). So when the currently playing video file ends, the next The opening and closing of an audio-visual slot has also been decoded, so it can be played immediately, greatly shortening the playback interval between the video files. - Step 14 towel, the length of the predetermined time can be based on the processing capability of the playback device (ie, how much time is required to decode the audio and video files), the format of the audio and video (the same as the format required), and the user's visual needs (acceptable spacing bars) are determined by factors such as The best example process, this post can play multiple health video files continuously in the playback split to improve the convenience of use, and make the 1248552 playback process smoother, without causing interruption for too long, to enhance playback 裴The continuous play function is described in detail above with reference to the preferred embodiments, and is not intended to limit the scope of the present invention. Those skilled in the art will be able to understand the details and make minor changes and adjustments. Without departing from the spirit and scope of the present invention, the specificity of the implementation of the present invention has been met with the requirements of the invention patents stipulated in the Patent Law.
