Paper Abstract:
|
In order to manage and utilize distributed campus network environment efficiently, a video transmission scheme has been
designed for simultaneous communication among multiple areas. The scheme is organized with DVTS (Digital Video
Transmission System)-based functional unit, which consists of a specified server, a digital video encoder, client devices
and so on. This paper introduces design of our video transmission scheme, formulation procedure for its performance
evaluation and demonstration of quantitative evaluation for its application to network conference in a real distributed
network environment. Design concept of the video transmission scheme is scalability form one-to-one communication to
the more multipoint one. Formulation is described for a case that each system for video transmission is located on the
different IP segment and communicates each other and/or one another simultaneously. Experiment for our systems on a
real distributed campus network environment are carried out in order to achieve practical communication based on video
transmission. And our paper also illustrates a summary of the above performance evaluation and an attempt of problem
solving which has happened on such a real experiment. |
