RTP/I Payload Type Definition for Telepointers

This document specifies an application-level protocol (i.e., payload type) for telepointers using the Real Time Protocol for Distributed Interactive Media (RTP/I). RTP/I defines a standardized framing for the transmission of application data and provides protocol mechanisms that are universally needed for the class of distributed interactive media. A telepointer creates a common point of reference in distributed (i.e., multi-user) applications by visualizing mouse movements of remote session participants. Telepointers are used in conjunction with other distributed interactive media such as shared whiteboards and distributed virtual environments. This documents specifies how to employ two-dimensional telepointers with RTP/I and defines application data units (ADUs) for telepointer operations. This protocol definition allows standardized collaboration between different telepointer implementations
