``EDIG is securely getting content on board NOW, aren`t they? So how is it they have no involvement in that realm (assuming that is the realm you`re referring to)?``
e.Digital is very much involved in the movement of the content to the DigE. That content is moving post production secured...through a specialized I/O authentication process...into yet a second secured environment. That second environment will keep the technicians working within the content management scheme from stealing.
Where in the TDL scheme the post production content files are decrypted before moving them forward into the final device.
IMO... for a completely closed system...the post production process at some point will evolve into the same process as the DigE....for carrying the data forward.
