A global-time-based approach for high-quality real-time video streaming services

This paper presents a global-time based approach for realizing high-quality real-time video streaming over networks. The application goal is to play the video streams at a remote site with minimal distortion of the temporal relationship among the video data units. The time-triggered message-triggered object (TMO) programming tool-kit, which enables construction of distributed real-time computing programs in the form of networks of high-level, easily analyzable, real-time objects, facilitates efficient practice of this approach. The experimental results of a feasibility evaluation of this global time based approach for real-time video streaming are also presented.
