Received changes through RFC Editor sync (changed abstract to 'The MPEG-2 standard defined by ISO 13818-1 supports a range of transmission methods for a variety of services. This document provides a threat analysis and derives the security requirements when using the Transport Stream, TS, to support an Internet network-layer using Unidirectional Lightweight Encapsulation (ULE) defined in RFC 4326. The document also provides the motivation for link-layer security for a ULE Stream. A ULE Stream may be used to send IPv4 packets, IPv6 packets, and other Protocol Data Units (PDUs) to an arbitrarily large number of Receivers supporting unicast and/or multicast transmission.

The analysis also describes applicability to the Generic Stream Encapsulation (GSE) defined by the Digital Video Broadcasting (DVB) Project. This memo provides information for the Internet community.')
