Abstract

An implementation method and an application of a personalized presentation of associated multimedia content are provided. The method includes steps of: by a multimedia content provider, uniformly completing full file content when producing a multimedia file, and classifying segments of the content through a marking method according to an importance and/or an association degree of the content, so as to produce different versions of the multimedia file; and selectively previewing and/or playing by a user according to the different versions. The present invention is a flexible and efficient method for scalable organization, storage and transmission in an Internet on-demand system, thereby adding a flexible organization mechanism for the media content that an existing multimedia protocol lacks, and solving problems of an existing multimedia system, such as low transmission efficiency, waste of storage resources and poor user experience.

First claim

What is claimed is:

1. 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 .

2. The implementation method of the multimedia content classification technology, as recited in claim 1 , wherein in the Type 1 , each level_list is composed of different MPU segments, and has a one-to-one correspondence with corresponding version of the content; when the user needs more segments, a server only needs to transmit missing MPU segments to the user; and in the Type 2 , each level list is composed of different MPU segments, and no overlapping MPU segment exists between each level_list; the different versions of content are composed of different level_list; when the users want to view a full version after viewing a clipped version, only MPU segments contained in the specific level list are required to be transmitted differentially.

3. The implementation method of the multimedia content classification technology, as recited in claim 2 , wherein MUR information is added to signaling information through adding the MUR information to an existing Composition Information (CI) the, through adding an MUR the that describes the MUR information to the signaling information, through adding a descriptor that describes the MUR information, wherein the descriptor is descriptive information for defining some fields or functions in a signaling part of an MPEG Media Transport (MMT) protocol, or through adding a signaling table that describes the MUR information.
