A Taxonomy of Semantics and Mechanisms for
Real-Time Transport Protocol (RTP) Sources
Abstract
The terminology about, and associations among, Real-time Transport
Protocol (RTP) sources can be complex and somewhat opaque. This
document describes a number of existing and proposed properties and
relationships among RTP sources and defines common terminology for
discussing protocol entities and their relationships.
