An approach for stream transmission over HLA-RTI in Distributed Virtual Environments
Hui Zhao, N.D. Georganas · 2003
The HLA-RTI provides a general-purpose network communications mechanism for Distributed Virtual Environments (DVE) but does not provide a stream transmission mechanism directly. This paper introduces a solution for stream transmission over RTI. This solution uses RTI-APIs sendInteraction() and receiveInteraction() to transfer stream data and uses the operating system interval timer to control schedule. An audio retrieve application is illustrated as an experiment with performance analysis. Finally, as a discussion, an architecture of videoconference federates based on this approach is introduced.
