Abstract

A technique for distributing in a multicasting network media content via two or more media layers is described. The media layers are hierarchically arranged in accordance with a scalable coding protocol such as the Scalable Video Coding (SVC) protocol. In a method implementation of this technique, in a first step a first number of media recipients for a first media layer that is transmitted via a first bearer of the multicasting network is determined. Then, a second bearer of the multicasting network for at least one second media layer is selected taking into account the first number and a hierarchical relationship between the first media layer and the second media layer.
