Introduction

The principles described in this Annex should facilitate the development of effective conditionalaccess systems for digital broadcasting that are convenient for both subscribers and service providers, assuring reliable protection of information from unauthorized access.

The principles apply generally to the delivery of digital television services, sound services as well as multimedia and data broadcasting services. These principles apply to both Recommendation ITU-T H.220.0 transport stream packet and MMTP packet delivery to consumers over different media, such as digital terrestrial, digital cable, digital satellite and IP (Internet Protocol) broadcasting.
