This International Standard specifies the terminal for a service purchase and protection
system for digital broadcasts, called the 18Crypt system. It is applicable in all countries and
regions with suitably compliant broadcasting and multimedia distribution systems. Guidelines
for compatible broadcast services are given in this standard. The service purchase and
protection functions operate in a pure broadcast environment that may be combined with a bi-
directional interactivity channel.
This standard is applicable to the following broadcast systems.
a) IPDC over DVB-H systems ~/
IP datacast over DVB-H is an end-to-end broadcast system for delivery of any type of digital
content and services using IP-based mechanisms optimized for devices with limitations on
computational resources and battery. An inherent part of the IP datacast system is that it
comprises a unidirectional DVB broadcast path that may be combined with a bi-directional
mobile/cellular interactivity path. IP datacast is thus a platform that can be used for enabling
the convergence of services from broadcast/media and telecommunications domains (for
example, mobile/cellular). This standard specifies service purchase and protection for IP
datacast over DVB-H systems (see B.10.3 for an overview of references).
b) DVB T/CIS systems
DVB T/CIS systems are end-to-end broadcast systems for audio/video data that employ an
MPEG2 transport stream and use terrestrial, cable or satellite broadcast networks. This
standard specifies a system for the protection of these broadcasts in a pure broadcast
environment. In addition, this standard specifies how purchasing, key management and
registration may be carried out over an optional interactivity channel. The protection
technologies offered by this standard are designed to operate within an existing DVB
SimulCrypt environment (see B.10.2 for an overview of references).
c) MPEG2 TS-based IP systems
MPEG2 TS-based IP systems employ bi-directional IP networks for the (broadcast) delivery of
MPEG2 transport streams. This standard specifies a system for the purchase and protection
of services and content delivered via these networks. This standard is applicable to, for
example, DVB-IPI systems (see B.10.4 for an overview of references).
d) Non-MPEG2 TS-based IP systems
Non-MPEG2 TS-based IP systems employ bi-directional IP networks for the (broadcast)
delivery of audio/video or other data using IP protocols instead of an MPEG2 transport
stream. This standard specifies a system for the purchase and protection of services and
content delivered via these networks (see B.10.4 for an overview of references).
