Abstract
A method and system for playing movies with object-based sound complying with industry security standards using less processing power than the prior art, comprises an integrated media block in which, in non-real-time, encrypted audio files are decrypted. The object-based and channel-based audio data is then rendered to theater specific channels in non-real time. After the audio objects are rendered, the rendered audio is re-encrypted and stored for use at a later time. When the rendered movie is to be played in real time, the encrypted video and rendered encrypted audio files are streamed from the server, decrypted, forensically marked and played. Using the present invention, movies also can be downloaded and pre-processed while another movie is playing.
