Issues in Satellite Packet Video Communication.

Abstract

Recent advances in packet communication over satellite links make it now possible, for the first time, to seriously consider the application of this technology to real-time video transmission. Unfortunately, packet communication over satellite links poses several severe problems for real-time video applications: The data rate available on packet satellite links is usually below what is required for real-time video applications; this data rate is shared dynamically with many other users with unpredictable demands; the delay associated with any use of a geosynchronous satellite is very large; and the error characteristics vary as a result of many uncontrollable external factors. This paper discusses the problems, suggests several techniques to cope with them, and describes the application of these techniques in a real-time packet video communication system being implemented at ISI.
