Abstract
Digital TV broadcasting needs new cryptological tools for conditional access, copyright protection and image authentication. The aim of this paper is to overview the corresponding systems´ features. The description of a conditional access system is given. It is shown that equitable systems need the use of a trusted third party. The design of efficient copyright protection by watermarking images and image authentication by signatures are also briefly discussed
