Adaptive home surveillance system using HTTP streaming

Abstract

In this paper, we investigate the use of HTTP streaming in home surveillance system. First, we propose a dynamic resource allocation framework among the cameras. Under a set of constraints, e.g. link bandwidth and delay, our resource allocation solution decides which video versions will be requested from which cameras in order to maximize the weighted sum of utility for all cameras. The optimization, which is performed at the client, is based on a utility model for each video stream that takes into account not only perceptual quality but also the delay of a video stream. Video content is obtained through HTTP request/response transaction between the client and the cameras. The experiment results show that the proposed method is able to effectively improve the overall utility while still supporting low end-to-end delay and good perceptual quality for important cameras.
