Low power surveillance video coding system

In this demo, a low power H.264/AVC video encoding system is demonstrated for surveillance video compression, which is based on our proposed algorithms as difference detection and Hilbert transform based workload estimation. Two surveillance video coding schemes (with and without our proposed methods, respectively) are implemented on multi-core embedded platform and compared side by side. The power consumption of each encoding scheme is measured during video encoding and displayed explicitly to show a more than 60% power reduction introduced by the proposed methods. The reconstructed video is also synchronized and displayed as the video is encoded to present a maximum of 50 times higher encoding speed.
