There is provided a method including receiving a playback system identifier corresponding to a playback system, generating a blockchain corresponding to a content identifier identifying a content, wherein the blockchain is uniquely associated with the content identifier, establishing, in the blockchain, a block corresponding to the playback system identifier, sending an encrypted version of the content to the playback system, and in response to one or more updates to the blockchain by the playback system, providing a content encryption key to the playback system for decrypting the encrypted version of the content.

Blockchain configuration for secure content delivery

A process receives, from a registration server associated with a content playback environment, a playback system identifier and a public key. The playback system identifier and the public key correspond to a playback system. Further, the process generates a blockchain corresponding to a content identifier such that a block is established to correspond to the playback system identifier. In addition, the process encrypts, with the processor according to a content encryption key, content associated with the content identifier. The process also encrypts, with the public key, the content encryption key.

A process receives, from a media content server, media content. Further, the process performs a first playback, with a processor at a media playback device, of one or more sample files corresponding to the media content. The one or more sample files each corresponds to a distinct codec format. In addition, the process determines, with the processor at the media playback device, a confidence score for each of the one or more sample files. The confidence score is associated with one or more factors indicative of the distinct codec format being software-based or hardware-based. Finally, the process performs a second playback, with the processor at the media playback device, of at least a substantial portion of the media content according to the distinct codec format that is hardware-based.
