Title: Network Delay Estimation in Reverse Genlock Synchronized Display Walls
Language (ISO): en
Abstract: A tiled display wall is a combined screen composed of multiple individual displays. Without compromising display resolution, a scalable solution for building tiled display walls is proposed. Herein, each display node is solely equipped with an Internet protocol (IP) connection. As display nodes are independently free running, synchronization is required at the display refresh level and regarding the content. In this paper, we focus on the aspect of network forwarding delay estimation, which ultimately determines the accuracy of display phase synchronization of a tiled display wall following the Reverse Genlock paradigm as proposed by the authors earlier. We show that in both switched and shared medium networks, forwarding delay may be estimated with microsecond accuracy.
