The play management module 212 further includes a file navigation module 2120. In a preferred embodiment of the present invention, the slot system module 208 is responsible for managing a plurality of different format file names and file locations (also referred to as Logical Block Addressing (LBA)) in the storage medium 400. The management module 212 enables the playback control interface 210 to allow the user to perform a list of files in the sound format and a list of information in the video format according to the name of the file to be played. The play management module 212 is divided into a sound format, a video format, and an audio and audio interleave format according to the play settings from the user, to separately provide a sound format data list, a video format data list, and The sound and video alternate format M data list, and the data list according to the sound, video, and sound and video formats are respectively provided to the audio file navigation module 2122 in the file navigation module 2120, and the video file navigation mode. A video file navigation module 2124 and a normal file navigation module 2126 are used to control the play order. The file navigation module 2120 can be configured for the sound format stored in the play management module 212. The video format and the audio and video alternate format data list are used to set the playback process as a basis for subsequent playback. The playback engine module 214 includes a sound scene state machine 2142, a video scene state machine 2144, and a regular scene state machine 2146. The module 214 is based on the sound file guide navigation module 2122 The playback process provides a corresponding sound scene state machine 2142, wherein the played file contains a sound format file, so that the user can have a sound format file 1296756 ϊίί. In addition, the playback process of the navigation module 2124 of the navigation module 2124 provides a corresponding camera 2144. The towel is at least included in the video format file so that the user can independently control the video format file. In addition to the above = landscape state machine sound and video alternate format file will be controlled by the regular scene 2 / play. It should be noted that the sound scene state state machine 2144 has a sound format and a video format asset h early playback process, so the two can exist at the same time, that is, the sound and video files can be played independently at the same time, without mutual influences. At the same time, when the video file is interrupted, if the sound file is interrupted, the video field will not be affected by the sound file. It will continue to play. This is because the regular % state machine 2146 has no sound and video alternates. The format data list playback process, so the regular scene state machine 2146 exists separately. In addition, when the file to be played only contains the sound file, the sound, state machine 2142 provides the sound file navigation module to play the sound block "play" (st〇p) . m (pause) ^ - ΪiLr!!10US), fast forward (next) and other playback state control; when waiting, the case only contains the video file, the video scene state machine 2144 will report Navigation module Μ 24 auxiliary video playback required for the opening of the Γ it it stop:, fast-rotation and other state control; when the broadcast is to provide the age of this alternate broadcast required (10) start, stop reverse, Fast-rotation and other state control. In accordance with the architecture of the hybrid multimedia player described above, the embodiment of the present invention provides a hybrid multimedia playback to prevent sound: Ge 1296756 video playback is interfered with by one of the sound or the video, and the video is broken or broken. The method 'first explains the part of the continuous sound. Please refer to the second and third figures. First, a video free space 22042 is provided in the video data stream temporary storage area 2204 (step 100). Next, it is checked whether the video effective space 22042 is sufficient (step 1〇2), wherein the loading management module 206 checks the video effective space 22042 according to the current working information check procedure to ensure that the video effective space 22042 is at least greater than the temporary The amount of video data in the storage area 218 and the sum of the maximum amount of data that can be processed by the de-editing module 216. When the video effective space 22〇42 is insufficient, the load management module 206 will stop loading the work information about the video (step 104), and at the same time, the check program is set to the full state (fuu) state, and the management mode is loaded. Group 206 can then load the next piece of work information about the sound. On the other hand, if the video effective space 22 〇 42 is displayed as sufficient, when the video playback is suspended or stopped, the de-editing module 216 loads the video data currently being processed and the video data in the track temporary storage area 218 into the video. Space 22042 (steps 1〇6). In this step, the de-editing module 216 first stores the video data to be decoded in the original processing into the video data effective space=042, and then the video data in the temporary storage area 218 is also processed by the de-editing module 216. And storing the video effective space 22〇42 in sequence, and then re-working the space of the temporary storage area 218, so that the loading management module 206 can continue to load the working information about the sound in the temporary storage area; Then, the data of the subsequent de-editing module 216 is moved, so that the sound data can be sequentially decoded and played to ensure continuous sound. A third figure is a representation of a preferred embodiment of the continuous sound according to the present invention. A valid space is provided in the audio stream temporary storage area 2202 and the video stream temporary storage area 2204 1296756, which is a sound effective space 22022 and a video effective space 22042. When playing sound, it is assumed that video playback is currently in progress, while V!, V2, Vs are the video data to be decoded, A is the sound data to be decoded, and each data (including the size of Vi, V2', V3, etc. All are 16KB (Bytes), where % and a belong to the video and audio data to be moved, and V2 and Vs are the video data stored in the track temporary storage area 218. At this time, if the user sets to pause or stop the video playback. In the case of the full-load mode storage capacity of the video effective space 22024, it must be greater than 48 KB (V1 +% = 48 KB), so that all video data is completely loaded into the video effective space 22〇42, ^ vacated The space of the track temporary storage area 218 allows the sound data a to be played to enter the temporary storage area 218, and then the de-editing module 216 converts the sound to be decoded to the voice of the person to be successfully sold 22G22 for subsequent decoding.
