DLNA, DVB-CA and DVB-CPCM integration for commercial content management

DLNA can be considered as a good candidate for sharing user-generated contents among household networked consumer electronics. However, commercial content sharing requires a high degree of device protection that DLNA does not provides. We propose a solution supporting acquisition and post acquisition content protection by the integration of DLNA with DVB Conditional Access and DVB Content Protection & Copy Management. This article shows the design and implementation of a solution to improve commercial content management over DLNA.
