This document describes a Real-Time Transport Protocol (RTP) payload format for transporting phoneme and facial animation parameter (PFAP) streams over the Internet according to the TtsFAPInterface that is defined as an internal interface of an MPEG-4 client in ISO/IEC 14496-3 (MPEG-4 Audio, Subpart 6: Text-to-Speech Interface, TtsFAPInterface) [2]. A recovery strategy for loss-tolerant transmission of such streams is described.
