TMO structuring of a networked system for seamless streaming and tiled display of high-definition movies

Abstract

This paper presents a global-time based approach for realizing highdefinition video streaming and highly synchronous tiled display on multiple PC-oriented display nodes. The challenge is to minimize distortion of the temporal relationship among the fragments of video frames played across the display devices. The distortion arises due to the jitter in message transmission delay and the considerably autonomous operations of display nodes. The global-time based coordination approach looked promising as a cost-effective approach for facilitating highly synchronous tiled display and minimizing the collisions between data transmission activities and tile preparation and display activities. The Time-triggered Message-triggered Object (TMO) programming tool-kit, which enables construction of scalable distributed real-time computing programs in the form of networks of high-level, easily analyzable, real-time objects was used because it facilitates efficient practice of the global-time based approach. The results of an experimentation of the approach are also presented. © TFIP International Federation for Information Processing 2007.
