The metadata block stores the characteristics of the block and the multimedia data. Metadata. The multimedia here; = the yuan poor block is, for example, the first memory in the memory, and then write more people's = 'S650), and when writing, the metadata block is placed in the multimedia resource ^, worth - mention The types of multimedia materials mentioned above include but not video, audio and subtitles (4), and (4) multimedia data that should not be recorded. The generated metadata blocks also record different multimedia = data characteristics. The metadata corresponding to the video data records, for example, the number of video channels, the number of video frames, the type of video frame, the time, size and length of each video frame, and the metadata corresponding to the audio data. For example, the number of audio tracks of the audio data, the time, size and length of each audio frame of the audio frame are recorded; and the data corresponding to the subtitle data records the number of subtitle tracks, the number of subtitles, and the subtitles of the subtitle data. Information such as time, size and length. In step S650, each time a set of multimedia data blocks and metadata blocks are written into the multimedia file, a record of a set of multimedia materials is completed. However, 'actually in the production of multimedia files, it usually includes recording multiple multimedia materials' and these multimedia materials are usually stored in video data, the audio 16 1334308 24091twf.doc/p data and the subtitle data are interleaved. In the multimedia file. Therefore, after each record of the multimedia data block and the metadata block is completed, the method further includes determining whether another multimedia data block is to be written into the multimedia file (step S660), and if there are still other multimedia data blocks to be written, Going back to step S620, and repeating steps § 620 to S650 above, other metadata blocks and other multimedia data blocks are generated in the multimedia file. Finally, when all the multimedia data blocks are written into the multimedia file, the present invention also includes the data for recording the mutual relationship of the multimedia materials in the multimedia standard file for the purpose of making the multimedia file common to various multimedia players. The establishment of the Xie Cong multimedia trough case and the reading of the metadata block to obtain the interrelationship data of the multimedia data, and the index table for generating the interrelationship of the recorded multimedia data in the multimedia building case (step S670) ). In one aspect, if the multimedia file is in the ISO-MP4 format, for each multimedia material in the multimedia file, a time to sample table and a sample pair data block table (sample) are created. To chunk table), sample size table (sampie size table), sync sample table (sync sample table) and chunk offset table (funk offset table) 5 index tables. Therefore, if the multimedia file includes a total of n (n is a positive integer) multimedia material, 5n index tables are generated correspondingly, wherein the index tables are in the header. In another aspect, if the multimedia file is, for example, in the AVI format, only an index table is created to record the interrelationship of the plurality of multimedia materials in the multimedia file, wherein the index table is located after the multimedia material area. 17 1334308 24091twf.doc/p It is worth noting that, in an embodiment, the above-mentioned cable is based on the metadata in the multimedia file after all the media data blocks are written into the multimedia file. Block build. However, in another embodiment, the index table may also be used to scan a multimedia data block for each metadata block and multimedia data block to the multimedia file. Stored in memory. Finally, when all the multimedia data blocks are written into the multimedia project, the index table stored in the memory is updated and ^^

Media file. After Ma Xi added the above index table to the multimedia file, the entire multimedia file generation process is completed, and the multimedia file can be recorded in the recording medium readable by a multimedia player such as a hard disk such as a hard disk.
