Abstract
A digital video management device enables controllably viewing digital video streams captured by remote surveillance cameras on a display device, such as a mobile display device. The device is coupled to a packet-switched network to receive a digital video stream captured by a remote surveillance camera. The device buffers packets of the digital video stream and then controls a packet output flow rate of the buffer between a zero output rate and a faster-than-real-time output rate. For example, the packet output flow rate can be set to the zero output rate at a first time and the faster-than-real-time output rate at a second time subsequent to the first time.
