| Abstract: | Digital Video Recording (DVR) systems have been popular these years following the rapid development of digital video devices and video coding techniques. A DVR is a computerized surveillance system that supports all the features of traditional videotape system by using digital cameras, motion detector, pan & tilt controls, capture cards and a computer. It can save the captured frames as harddisk files, which can be playbacked later. Another advantage of DVR is that it supports real-time remote display of the captured video frames while the digital recording is working at the same time. In this paper, we present the research on the real-time remote display of a DVR system, especially the congestion control algorithm for the multi-channel transmission case. Our proposed congestion control algorithm can achieve efficient and stable real-time transmission of multi-channel captured video sequences for a wide range of bandwidth capacity. The algorithm is also TCP-friendly as it follows the Additive Increase Multiplicative Decrease (AIMD) scheme. Several trade-offs are made to fit for the special purpose of remote surveillance. | ||
