Abstract
Systems and methods for providing access to various resolutions of a video. In one instance, a selection is received of a video resolution from a plurality of video resolutions, wherein the plurality of video resolutions are associated with the video. A determination is then made as to whether to authorize access to the selected video resolution based on a digital right associated with the video resolution. Depending on the determination, the video is displayed at the selected video resolution. In addition, the video may include one or more video layers, and each video layer may correspond to a particular video resolution. Further still, one or more of the video layers may be encrypted and protected by a digital right. Moreover, the encryption technique used to encrypt the video layers of the video may be different for each of the video layers.
