1. A method of multicasting a multimedia stream, comprising the steps of:
- receiving a request to perform a multicast;
assigning a plurality of distribution nodes to provide said multicast to a plurality of receivers, an assignment of at least one of said nodes based upon transformation capability of said node;
performing said multicast;
performing a transformation of said multicast at said node;
distributing said transformed multicast to at least one receiver which is suitable for receiving said transformed multicast.

Abstract
A multimedia stream is multicasted. A request to perform the multicast is received. A plurality of distribution nodes are assigned to provide the multicast to a plurality of receivers. The assignment of a node is based on the transformation capabilities of that node. The multicast is then performed and the assigned node performs its transformation. The transformed multicast is distributed to a receiver which is suitable for receiving the transformed multicast.
