Abstract

A method for assigning video signals includes receiving a plurality of video signals from a plurality of cameras located at one or more remote sites, the plurality of video signals for display on a plurality of monitors at a local site. The method includes determining an optimal monitor for displaying a first video signal associated with a first camera based on the location and alignment of the first camera in relation to one or more of the plurality of cameras. The method includes calculating a respective difference between a number of video signals assigned to the optimal monitor and a respective number of video signals assigned to each respective monitor of the plurality of monitors. The method further includes assigning the first video signal to the optimal monitor if the respective difference is not greater than a threshold value with respect to each of the plurality of monitors.

wherein the one or more other video signals are associated with one or more other cameras of the plurality of cameras;

wherein the first position is determined based on;

the location and alignment of the first camera relative to the one or more other cameras; and

a number of the plurality of video signals relative to a number of the plurality of monitors; and

display the first video signal at the first position on one of the plurality of monitors.

7. The system of claim 6:

wherein the interface is operable to receive a new video signal from a new camera located at a remote site; and

wherein the one or more processors are operable to;

in response to receiving the new video signal, determine a new position for displaying on one of the plurality of monitors the first video signal;

wherein the new position is determined based on;

the location and alignment of the first camera relative to the one or more other cameras and the new camera; and

a number of the plurality of video signals and the new video signal relative to the number of the plurality of monitors; and

display the first video signal at the new position on one of the plurality of monitors.
