This thesis examines the perceived effectiveness of Internet's Multicast Backbone (MBONE) compressed-motion video-teleconferencing system and analyzes its capabilities and limitations. The analysis follows the media richness model of media choice and discusses seven influences on a managers' media selection. This study expands the video-teleconferencing branch of the continuum of communication media to include compressed-motion video-teleconferencing and the distinguishing factors between systems. The study uses data gathered from the Monterey Bay Aquarium Research Institute's (MBARI) Internet conference experiment to compare MBONE versus face-to-face viewer perceptions of the different communication media and to support the theoretical analysis. The survey instrument used to gather data is presented in this thesis. Research results showed that the compressed-motion video image of MBONE filtered and restricted the conveyance of some non-verbal cues and that feedback could be delayed in one-to-many situations. MBONE is found to be more effective for reducing uncertainty than resolving equivocal communication situations. This framework for analysis will enable those responsible for the selection of communication media within the Department of Defense (DoD) to have a basis for distinguishing between choices of video-teleconferencing systems CD-ROMCD-RSystem Development Life Cycle.
