RTP Payload Format for V-DMC

This memo outlines RTP payload formats for the Video-based Dynamic Mesh Coding (V-DMC), which comprises several types of components, such as a basemesh, AC-based displacements, 2D representations of attributes, and an atlas. This document focuses on describing the basemesh and displacement, while the RTP payload formats for the atlas and attributes are addressed in other documents. The RTP payload header formats enable the packetization of a basemesh or displacement Network Abstraction Layer (NAL) unit in an RTP packet payload as well as fragmentation of a NAL unit into multiple RTP packets.
