Part III
The Media Plane in the IMS
Part III deals with the IMS media plane. We tackle several media types, although our focus is set on audio and video, especially in Chapter 15, where we describe how to represent audio and video signals in digital format using audio and video codecs. Chapter 16 describes how to transport encoded media in an IP network.
We follow a similar approach that we chose for Part II: we first introduce the technology and then explain how it is used in the IMS.
