摘要

With the advent of various many multimedia applications, efficient advertisement becomes important so that it could offer a good service model promoting the consumption of the charged contents and distributing them widely. In the service model, the advertisement is needed to be harmonized and represented with the main resources according to a business policy. In this paper, the effective advertisement insertion method is proposed to meet the aforementioned requirements in the service. The proposed method adopts MPEG-4 file format to encapsulate multimedia resources together and utilizes MPEG-21 DID to deliver rights and protection information of the embedded resources. To demonstrate the proposed method, this paper shows a unified file format to deliver advertisement as well as various multimedia resources. The various cases on content consumption by right management between advertisement and the main resources are also described.
