ITU-T.120 and It's Implementation for Real Time Collaboration

Abstract

The purpose of this thesis is to describe the design and implementation ol' :t multiplatform, desktop videoconferencing system lor the Intern et. First, the technologies and standards utilized currently lor the multimedia, real-time. co llaborative applications arc briefly described. Then, existing vidcoconferencing products arc presented and analyzed, identifying disadvantages and possible modifications. Based on the analysis, the objectives of the vid eocon l"erenci ng S) stem offering the basic functionality are formulated. At that point, the design that is most suitable for the assumed objectives is proposed, addressing the particu larly important issues of platfo rm independence and fl ex ibility. The implementation of this design on two most popular multimedia platforms is described in detai l, dealing with the encountered problems and pl atform specific· solutions. This part includes the presentation of the system components and th eir interactions, focus ing on standard compliance and interoperability. To prove the s: stem flexi bility in adapting to modern envi ronments, the integration with a Weh collaborative application is discussed. Summary of the system chnracteristics and the achieved goals concludes the thesis.
