The thesis gives the frame design from the perspective of the content integrity and security about the transmission of streaming media resources in the network, next to it, system requirements, functional structure, information structure, the overall structure and hierarchical structure are introduced..And then, thesis design the key modules of DRM system based on digital rights protecting technology.
