Abstract: A digital rights management (DRM) server receives data associated with a device security profile (DSP) from a content owner device. The DSP specifies requirements for client devices to access content items associated with a content owner. The requirements differ based on a resolution level of the accessed content items. The DRM server stores the DSP and an indication of the content owner. The DRM server receives, from a content server storing the content items associated with the content owner, a pull request for DSP updates. The DRM server transmits the DSP to the content server in response to the pull request. The DSP causes the content server to limit client devices that access the content items according to the DSP.

Abstract: According to an aspect, a computing device may include a media content handler to obtain media content, a group license manager to determine whether or not the media content is part of a license group, and when the media content is determined as part of the license group, the group license manager may determine whether a master key for the license group was previously received. The group license manager may send, over a network, a license request to a license manager when the master key was not previously received. The group license manager may receive, over the network, a license to permit access to the media content, where the license includes the master key. The computing device may include a key generator to derive a content key based on the master key, and a decryption unit to decrypt the media content using the derived content key.

Abstract: A system and method are directed towards including buffer packets into an unencrypted content stream at a same location as encryption related information such as an ECM, an EMM message, or the like, would be in a corresponding encrypted content stream. The buffer packets may comprise virtually any information, including a null packet, an ECM message. By inserting buffer packets in the same location, an overall file size, and frame locationing may be made to match the file size, and frame locationing of the encrypted content stream. The modified unencrypted content stream may be employed to generate trick play files, such as a fast forward file, fast reverse file, and so forth, as well as a corresponding index file that indicates locations of relevant content frames in the unencrypted content stream and the trick play files.

Abstract: A strong but lightweight garment hanger includes a unitary body that can be made of Aluminum or plastic. A hook support member depends down from the hook of the hanger, and first and second arm members extend down from the hook support member. For strength, each arm member includes an inner arm and an outer arm connected to the inner arm by connector segments. A lower support member extends between the arm members and includes upper and lower elements and a strengthening web between the lower and upper elements.
