By matching the data packets in the collection points, these embodiments can evaluate the distribution situation of the time delay in the video service in each network segment, and precisely locate the network segment or network element in which the time delay occurs.05-16-2013
20120019718MULTIMEDIA DEVICE CAPABLE OF DETECTING CONNECTION STATUS OF EXTERNAL DISPLAY DEVICES - A multimedia device generates and outputs video signals to a display component and an external display device, and includes a video output circuit and a load detection circuit. The load detection circuit isolates and buffers the video output circuit and the load detection circuit, and retrieves horizontal sync signals from the video signals. The load detection circuit further amplifies and integrates the retrieved horizontal sync signals to output direct current signals, and finally compares the direct current signals with a predetermined voltage to output a control signal indicating a connection between the video output circuit and the external display device. The multimedia device turns off the display component according to the control signal indicating that the video output circuit has been connected to the external display device.01-26-2012
