摘要
A new container format, a DRM method using the same, a system thereof, an advertisement providing method, and a system thereof are provided to divide contents into data for distribution and data for storage, thereby preventing pirate usage of the contents. Data for storage(303) includes a content ID of contents(302), index information, and a first image block or a first voice block. Data(304) for distribution includes a content ID, and a second image block or a second voice block. The first image block includes a pre-selected number of image blocks among the entire image blocks of the contents. The second image block includes the rest image blocks except the first image block among the entire image blocks.
