適用范圍：This International Standard specifies the terminal for a service purchase and protectionsystem for digital broadcasts, called the 18Crypt system. It is applicable in all countries andregions with suitably compliant broadcasting and multimedia distribution systems. Guidelinesfor compatible broadcast services are given in this standard. The service purchase andprotection functions operate in a pure broadcast environment that may be combined with a bidirectionalinteractivity channel.This standard is applicable to the following broadcast systems.a) IP datacast over DVB-H systemsIP datacast over DVB-H is an end-to-end broadcast system for delivery of any type of digitalcontent and services using IP-based mechanisms optimized for devices with limitations oncomputational resources and battery. An inherent part of the IP datacast system is that itcomprises a unidirectional DVB broadcast path that may be combined with a bi-directionalmobile/cellular interactivity path. IP datacast is thus a platform that can be used for enablingthe convergence of services from broadcast/media and telecommunications domains (forexample, mobile/cellular). This standard specifies service purchase and protection for IPdatacast over DVB-H systems (see Table B.6 for an overview of references to one suchsystem).b) DVB T/C/S systemsDVB T/C/S systems are end-to-end broadcast systems for audio/video data that employ anMPEG2 transport stream and use terrestrial, cable or satellite broadcast networks. Thisstandard specifies a system for the protection of these broadcasts in a pure broadcastenvironment. In addition, this standard specifies how purchasing, key management andregistration may be carried out over an optional interactivity channel. The protectiontechnologies offered by this standard are designed to operate within an existing DVBSimulCrypt environment (see Table B.6 for an overview of references).c) MPEG2 TS-based IP systemsMPEG2 TS-based IP systems employ bi-directional IP networks for the (broadcast) delivery ofMPEG2 transport streams. This standard specifies a system for the purchase and protectionof services and content delivered via these networks. This standard is applicable to, forexample, DVB-IPI systems (see Table B.6 for an overview of references).d) Non-MPEG2 TS-based IP systemsNon-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 transportstream. This standard specifies a system for the purchase and protection of services andcontent delivered via these networks (see Table B.6 for an overview of references).
