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. |
