Abstract: The invention provides an FEC (Forward error correction) mechanism based on media content. The mechanism classifies the media content, and endows it with different importance, and then changes the coding scheme according to the packets belonging to frames of different importance in combination with channel conditions and user experience, to conduct protection according to the importance of corresponding frames. By using the technical scheme of the invention, for the data congestion caused by excessive coding in the current FEC system, the media content is able to be classified and endowed with different importance, and controlled by signaling and indicating bit; different FEC coding strengths is able to be adopted; the duplication-expanding window fountain code with the unequal error protection performance is able to be further adopted, to achieve the maximum guarantee of media content quality and reduce the large amount of data caused by FEC.

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.
