Given the seemingly insatiable desire for low-cost and highly capable mobile computing devices in the form of personal digital assistants (PDAs), and the increasing popularity and deployment of wireless networks it was inevitable that video services would be a target for network deployment. Unfortunately wireless networks currently available rarely support data rates approaching those necessary for full motion video. At The Network-Centric Applied Research Team (N-CART), we are attempting to introduce workable service architectures dealing with this reality. We have developed a prototype service delivery model allowing both low-bandwidth video to be generated for and displayed on a PDA as well as allowing real-time control of the video source–in our case a robot. We have applied this model to our MAX teleoperation project.
