Digital Video Broadcasting Conditional Access Architecture

چکیده
Digital Video Broadcasting (DVB) is a standard defining a one-to-many unidirectional data network for sending digital TV programs over satellite, cable, and other topologies. The standard enables the broadcasting industry to offer hundreds of pay-TV channels to consumers. The expanded capacities make the broadcast signals more valuable and attractive to signal thefts [1]. To protect a DVB data-network, the DVB standard integrates into its broadcasting infrastructure an access control mechanism, commonly known as Conditional Access, or CA for short [3].

An Efficient Hierarchical Modulation based Orthogonal Frequency Division Multiplexing Transmission Scheme for Digital Video Broadcasting
Due to the increase of users the efficient usage of spectrum plays an important role in digital terrestrial television networks. In digital video broadcasting, local and global content are transmitted by single frequency network and multifrequency network respectively. Multifrequency network support transmission of global content and it consumes large spectrum. Similarly local content are well ...

We describe a concept to employ Trusted Computing technology to secure Conditional Access Systems (CAS) for DVB. Central is the embedding of a trust anchor, e.g. a trusted platform module (TPM) into the set-top box or Conditional Access Module. Various deployment scenarios exhibit possibilities of charging co-operation with mobile network operators (MNO) via trusted mobile devices, or with othe...

Geostationary satellite networks are currently considered as one of the most promising broadband access network technology for narrowing the digital divide. Though technically attractive and cost effective, the provisioning of endto-end QoS services in satellite access remains largely undefined. In order to bridge this gap, the European SATIP6 project defines a complete QoS architecture involvi...
