See full text

Techniques for generating an encrypted video bitstream include encrypting media data using a plurality of encryption keys and generating metadata associated with the encrypted media data. The metadata includes a first list based on the plurality of encryption keys and a second list based on initialization vector/feedback vector (IV/FV) information to facilitate independent decryption of at least one encrypted video frame included in the encrypted media data.
