Abstract

In this paper, we want to point out similarities and differences between digital Pay-TV, which uses MPEG-2 transport streams, and its future analogue for IP based services, which we call Pay-Streaming. After an introduction to encryption, re-keying and key management in the European DVB model for Pay-TV, we consider existing (IPSec, IP multicast) and missing (key management) building blocks for Pay-Streaming in the Internet. We conclude with a discussion of some practical aspects related to the standard PC architecture.
