Design of video players system for multi-projector tiled display wall

Abstract

Recent interests in large displays has led to the rapid development of multi-projector tiled display wall systems, which comprises of an array of individual projectors, and usually driven by a cluster of PCs. Here we design a video players system for playing video streams on tiled display wall systems. The video players system includes two components, server and a set of client players. The server decodes and divides the video streams selected by users, and then broadcasts the video segments to each client players according to their positions. Each client players renders the video segments sent by the server, and deals with geometry calibration and color calibration problems based on preset calibration matrix. Test results show that the above players system can play multiple types of video with high quality and high performance.
