The playback engine module 214 provides a corresponding sound scene state machine 2142 according to the playback process of the sound slot method and the navigation module 2122, wherein the played file has at least a sound format file, and the user can independently control the file containing the sound format. . In addition, the playback engine module 214 can also provide a corresponding video scene state machine 2144 according to the playback process of the video file navigation module 2124. The played file includes at least a video format file, so that the user can independently control the video format file. . In addition to the above two scene state machines, the video and audio alternate format slot will be played back by the regular scene state machine 2146. In addition, according to the user's playback control, the playback engine module 214 generates a corresponding job request information (job request) to be loaded into the load management module (1〇ader_age; module) 206. The loading management module 2G6 generates corresponding job information (job) based on the job request information. The job information includes the file to be played, the start and end addresses (Logical Block Addressing, LBA) loaded in the storage medium 400, and the execution 顺$. The execution order further includes a usage state (state), a priority value jprionty, and an exit functi (n). And the generations can be divided into emergency, towel, etc., full load status. It should be noted that the priority order of execution of the ϋΐ ϋΐ 系 系 系 系 系 系 优先 优先 优先 优先 优先 优先 优先 优先 优先 优先 优先 优先 优先 优先 优先 优先 优先 优先 优先 优先In general, the information is not ranked as the highest priority, and the rest is returned as the second priority. In addition, with the status of the backhaul code ( ίί ϊΐϊϋ (emergency, medium, full load), J edge rises k first handle value. Since the file system module 2〇8 is responsible for 1290299 managing the file directory and the location of the file in the storage medium 400, it is also a logical block address (LBA). According to the user's play control, the file navigation module 2120 will attach the file to be played by the user stored in the file system module 208 to the file to be played. When the play engine module 214 generates work request information, the load management module 206 generates corresponding work information according to the work request information and integrates them into a work list (sequentially arranged according to the priority value), and transmits the load mode. Group 204 reads a particular address of storage medium 400. The data to be played by the user is transmitted to the executable storage area 218 via the load module 204. Then, the data to be played is then transmitted to the de-editing module 216 by the obsolete temporary storage area 218, and finally transmitted to the audio stream temporary storage area 2202 and the video stream temporary storage area 2204 in the streaming temporary storage area 220. According to the architecture of the hybrid multimedia player, a preferred embodiment of the present invention provides a method for checking job information in a multimedia player to determine a loading candidate. Referring to the second figure, the checking method is performed in sequence. The following steps: First, a work information form is created (step 100). The work information form (refer to the third figure at the same time) has a block ranked according to the priority value, and the usage status of each work letter of the work information form is preset to a "waiting" state, the work information form The requesting unit such as the file system module 208, the play management module 212, and the play engine module 214 requests the load management module 206 to make a request, and the target information is used in addition to the priority value and the use status. The selective backhaul code and the logical block location (such as the storage medium is the disc, the address data refers to the light) on the slice of the logical block (LQgieal Β1 (χ± tonaga, 1290299 LBA) Next, the load management module 206 sequentially sorts the work request according to the priority value provided by the request unit into the corresponding block of the work information form (step 102). When one work information block is used, The next applicant can block an unused job information after the job information is blocked, and the corresponding work information usage status is changed to "waiting". With the ^, the entry management module 206 checks The work on the i-th work information block (step 104). It should be noted that when the load check is performed for the first time, it is recognized that the load management module has priority to execute the work information. The highest priority value of the job information block, in addition, each complete cycle (check the complete work letter A form-side i side position according to the priority value of the priority value), and the person's work ^ is re-s Han i = ; [, to determine the next-to-be-loaded job information. Next, check if the usage status of the job information block is "中i"-like J main (f-strict). When the work information field If ^ is 4 in the middle, otherwise check the next job information block (i=i+ step,); if it is, check whether the read message has a return code (step yo). The right cylinder has a return code. 'Set the current view confidence field as the next tentative person to manage the mansaki to be manned, and set i = i + 1 (step 112) after j 4 followed = line.
