Abstract
This paper proposes a general solution for the multi-source high resolution real-time monitoring system. Our proposed system is realized on a PCI bus-based real-time image processing board, based on H.264 video compression standards. The main function of the system includes video decompression, image scaling, image stitching, as well as multi-mode real-time display in PC software. Unlike traditional multi-board based multi-source surveillance system, our solution focuses on single board system with synchronously processing and independently display of multi-source video, which is more resource-saving The main contributions of this paper are twofold: firstly, we propose a new logical control method of multi-thread to overcome the limitation of single-board bandwidth, and secondly we give a DirectDraw based display solution to avoid screen flicker caused by different frame rates of multi-source. In addition, we elaborate an approach on multi-thread control and synchronization to reduce CPU utility and monitor abnormal system condition.
