Abstract

This paper describes the requirements for a graphical format on which to base a graphical on-line communication protocol. It is argued that on-line graphical communication is similar to graphical session capture, and thus we propose an Interactive Graphical Communication Format using the GKSM session metafile.

ABSTRACT

This paper describes the requirements for a graphical format on which to base a graphical on-line communication protocol. It is argued that on-line graphical communication is similar to graphical session capture, and thus we propose an Interactive Graphical Communication Format using the GKSM session metafile.

We discuss the items that we believe complement the GKSM metafile as a format for on-line interactive exchanges. One key application area of such a format is multi-media on-line conferencing; therefore, we present a conferencing software architecture for processing the proposed format. We make this format specification available to those planning multi-media conferencing systems as a contribution toward the development of a graphical communication protocol that will permit the interoperation of these systems.

We hope this contribution will encourage the discussion of multimedia data exchange and the proposal of solutions. At SRI, we stay open to the exploration of alternatives and we will continue our research and development work in this problem area.

ACKNOWLEDGEMENTS

The author wants to thank Andy Poggio of SRI who made many insightful and valuable suggestions that trimmed and improved level U. His expertise in multi-media communication systems and his encouragement were a most positive input to the creation of this IGCF. Dave Worthington of SRI also participated in the project discussions involving this IGCF. Thanks are also due to Tom Powers, chairman of ANSI X3H33, who opened this forum to the presentation of an earlier version of this paper, thereby providing an opportunity for the invaluable feedback of the X3H33 members. Jon Postel of ISI recommended a number of changes that made this paper more coherent and accessible.

I. INTRODUCTION

A. Use of a Graphical Communication Protocol

In the field of computer communications, a protocol is a procedure executed by two cooperating processes in order to attain a meaningful exchange of information. A graphical communication protocol is needed to exchange interactive vector graphics information, possibly in conjunction with other information media like voice, text, and video. Within this multi-me...
