Abstract

A video monitoring system includes a video monitor configured to receive a video image from a video source such as a video camera, decompress the video image, and display the video image on a display screen according to a display format. The video monitor may be used to adjust one or more video parameters of the video image. The video monitor may be configured to transmit the video image to a remote video device such as a remote video monitor (42) or video recorder. The video monitor (12) may also be configured to retrieve video parameter values from the remote video device(s) and modify the video parameters of the video image based thereon.
