Implemental method and application of personalized presentation of associated multimedia content

An implementation method of multimedia content classification technology, comprising steps of:

• cutting a multimedia file into multiple Media Processing Unit (MPU) segments, wherein each MPU segment has a different mark field therein;
• classifying all of the MPU segments into different levels according to an importance of multimedia content, so that a user is able to selectively play the multimedia content according to the levels, instead of selecting blindly and randomly, and the MPU segments of same level form one version of content;
• and defining a new Media Unit Relationship (MUR) information file for describing corresponding relationships between the multimedia file and different versions of content, mpu_seq_number and level list, wherein:
• each mpu_seq_number is the mark field in each MPU segment;
• each level list represents a set of mpu_seq_number;
• correspondence rules between a level_list array and the different versions of the content are different and are able to be divided into two types, wherein:
• in Type 1, a one-to-one correspondence exists between each version of the content and the corresponding level list in the level list array;
• and in Type 2, the different versions of the content are combinations of the different level_list;
• and a differential transmission of the multimedia file is preformed according to content of the MUR information file in the Type 1 and the Type 2.
