Abstract
Methods, systems, computer-readable media, and apparatuses for providing policy-based copyright enforcement of media content items streamed to client devices are described. Various aspects discussed herein relate to managing content access rights in an adaptive bitrate environment (e.g., where an asset may be encoded and delivered at multiple different bitrates). The system discussed herein permits differentiated access to the same video, or portions of the same video, where any DRM-type client may read a manifest file including content verification data, which may be video authentication information that is specific to the video. Additional aspects discussed herein provide DRM metadata specific to each frame of a multi-bitrate video to enable the client device to verify the multi-bitrate video on a frame-by-frame basis.
