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.
