Abstract
Devices, systems and methods for distribution of digital content are provided. At least a security manager of a media block is located within a tamper-responsive enclosure, the security manager and/or the media block bonded to a transcoder in a security marriage based on a cryptographic certificate associated with at least the media block. The media block provides, to the transcoder via a data bridge, encrypted output generated from digital content and based on a first cryptographic key. The transcoder generates respective transcoded outputs associated with one or more tokens used for playback of the respective transcoded outputs at respective end-user devices, the respective transcoded outputs generated from the encrypted output decrypted using a second cryptographic key associated with the first cryptographic key. The respective transcoded outputs are output to the respective end-user devices associated with respective tokens.
