Therefore, the concept of digital rights management has been proposed to manage the right of using digital media contents. However, due to DRM mechanisms still can’t prevent piracy completely, it cause inconvenience to legitimate users and the development of DRM is also been hindered. In this paper, we propose a new method. We use the video quality control with DRM. It can achieve the purpose of commercial protection without affecting paid users. Therefore, we present a layered video DRM mechanism by Multiple Description Coding based on H.264/AVC. This method provides not only high quality for paid movies but low quality for free movies to create a situation that conducive to manufacturers, consumers and general publics.
