Abstract

An apparatus and method can test multiple signal channels of a digital video recorder (DVR). Image data are obtained from a storage device and converted the image data to a video signal. The DVR sends the video signal to an image distributor, and generates a selection command to a controller for controlling the image distributor to select a signal channel to be tested. After the video signal is received from the DVR, the image distributor sends the video signal to the selected signal channel. An ID number of the selected signal channel is displayed on a display device when the DVR does not receive the video signal from the selected video channel.
